A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2099-2101; Curr Opin Oncol 1998 Jan;10(1):43-51)
A cell line derived from cultured tumor cells.
A benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. Histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. The tumor may present clinically with HORNER SYNDROME or diarrhea due to ectopic production of vasoactive intestinal peptide.

Family of retrovirus-associated DNA sequences (myc) originally isolated from an avian myelocytomatosis virus. The proto-oncogene myc (c-myc) codes for a nuclear protein which is involved in nucleic acid metabolism and in mediating the cellular response to growth factors. Truncation of the first exon, which appears to regulate c-myc expression, is crucial for tumorigenicity. The human c-myc gene is located at 8q24 on the long arm of chromosome 8.
A moderately malignant neoplasm composed of primitive neuroectodermal cells dispersed in myxomatous or fibrous stroma intermixed with mature ganglion cells. It may undergo transformation into a neuroblastoma. It arises from the sympathetic trunk or less frequently from the adrenal medulla, cerebral cortex, and other locations. Cervical ganglioneuroblastomas may be associated with HORNER SYNDROME and the tumor may occasionally secrete vasoactive intestinal peptide, resulting in chronic diarrhea.
A malignant olfactory neuroblastoma arising from the olfactory epithelium of the superior nasal cavity and cribriform plate. It is uncommon (3% of nasal tumors) and rarely is associated with the production of excess hormones (e.g., SIADH, Cushing Syndrome). It has a high propensity for multiple local recurrences and bony metastases. (From Holland et al., Cancer Medicine, 3rd ed, p1245; J Laryngol Otol 1998 Jul;112(7):628-33)
A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.
Benign and malignant neoplastic processes arising from or involving components of the central, peripheral, and autonomic nervous systems, cranial nerves, and meninges. Included in this category are primary and metastatic nervous system neoplasms.
A subclass of ACIDIC GLYCOSPHINGOLIPIDS. They contain one or more sialic acid (N-ACETYLNEURAMINIC ACID) residues. Using the Svennerholm system of abbrevations, gangliosides are designated G for ganglioside, plus subscript M, D, or T for mono-, di-, or trisialo, respectively, the subscript letter being followed by a subscript arabic numeral to indicated sequence of migration in thin-layer chromatograms. (From Oxford Dictionary of Biochemistry and Molecular Biology, 1997)
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in neoplastic tissue.
Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as MULTIPLE MYELOMA. Most bone marrow neoplasms are metastatic.

"Neurite" may refer to any filamentous or pointed outgrowth of an embryonal or tissue-culture neural cell.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Glycopeptides from the surgace of human neuroblastoma cells. (1/5127)

Glycopeptides suggesting a complex oligosaccharide composition are present on the surface of cells from human neuroblastoma tumors and several cell lines derived from the tumors. The glycopeptides, labeled with radioactive L-fucose, were removed from the cell surface with trypsin, digested with Pronase, and examined by chromatography on Sephadex G-50. Human skin fibroblasts, brain cells, and a fibroblast line derived from neuroblastoma tumor tissue show less complex glycopeptides. Although some differences exist between the cell lines and the primary tumor cells, the similarities between these human tumors and animal tumors examined previously are striking.  (+info)

Expression of the naturally occurring truncated trkB neurotrophin receptor induces outgrowth of filopodia and processes in neuroblastoma cells. (2/5127)

We have investigated the effects of the truncated trkB receptor isoform T1 (trkB.T1) by transient transfection into mouse N2a neuroblastoma cells. We observed that expression of trkB.T1 leads to a striking change in cell morphology characterized by outgrowth of filopodia and processes. A similar morphological response was also observed in SH-SY5Y human neuroblastoma cells and NIH3T3 fibroblasts transfected with trkB.T1. N2a cells lack endogenous expression of trkB isoforms, but express barely detectable amounts of its ligands, brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT-4). The morphological change was ligand-independent, since addition of exogenous BDNF or NT-4 or blockade of endogenous trkB ligands did not influence this response. Filopodia and process outgrowth was significantly suppressed when full-length trkB.TK+ was cotransfected together with trkB.T1 and this inhibitory effect was blocked by tyrosine kinase inhibitor K252a. Transfection of trkB.T1 deletion mutants showed that the morphological response is dependent on the extracellular, but not the intracellular domain of the receptor. Our results suggest a novel ligand-independent role for truncated trkB in the regulation of cellular morphology.  (+info)

p73 at chromosome 1p36.3 is lost in advanced stage neuroblastoma but its mutation is infrequent. (3/5127)

p73, a novel p53 family member, is a recently identified candidate neuroblastoma (NBL) suppressor gene mapped at chromosome 1p36.33 and was found to inhibit growth and induce apoptosis in cell lines. To test the hypothesis that p73 is a NBL suppressor gene, we analysed the p73 gene in primary human NBLs. Loss of heterozygosity (LOH) for p73 was observed in 19% (28/151) of informative cases which included 92 mass-screening (MS) tumors. The high frequency of p73 LOH was significantly associated with sporadic NBLs (9% vs 34%, P<0.001), N-myc amplification (10% vs 71%, P<0.001), and advanced stage (14% vs 28%, P<0.05). Both p73alpha and p73beta transcripts were detectable in only 46 of 134 (34%) NBLs at low levels by RT-PCR methods, while they were easily detectable in most breast cancers and colorectal cancers under the same conditions. They found no correlation between p73 LOH and its expression levels (P>0.1). We found two mutations out of 140 NBLs, one somatic and one germline, which result in amino acid substitutions in the C-terminal region of p73 which may affect transactivation functions, though, in the same tumor samples, no mutation of the p53 gene was observed as reported previously. These results suggest that allelic loss of the p73 gene may be a later event in NBL tumorigenesis. However, p73 is infrequently mutated in primary NBLs and may hardly function as a tumor suppressor in a classic Knudson's manner.  (+info)

Cadmium-mediated activation of the metal response element in human neuroblastoma cells lacking functional metal response element-binding transcription factor-1. (4/5127)

Metal response element-binding transcription factor-1 (MTF-1) binds specifically to metal response elements (MREs) and transactivates metallothionein (MT) gene expression in response to zinc and cadmium. This investigation contrasts the mechanism of mouse MT gene (mMT-I) promoter activation by cadmium and zinc in IMR-32 human neuroblastoma cells to determine whether MTF-1 binding to the MRE is necessary for activation by these metals. Cadmium activated a mMT-1 promoter (-150 base pairs) luciferase reporter 20-25-fold through a MRE-dependent mechanism. In contrast, zinc had little effect on the mMT-1 luciferase reporter. IMR-32 cells lacked MRE binding activity, and treatment with zinc in vitro or in vivo did not generate a MTF-1. MRE complex, suggesting that IMR-32 cells lack functional MTF-1. Overexpression of mMTF-1 regenerated a zinc-mediated induction of the MRE without affecting cadmium activation. Because no other transition metals tested activated the MRE, this effect appeared to be cadmium-specific. These data demonstrate that in IMR-32 human neuroblastoma cells, zinc and cadmium can use independent mechanisms for activation of the mMT-I promoter and cadmium-mediated MRE activation is independent of MTF-1 and zinc.  (+info)

Inhibition of angiogenesis induces chromaffin differentiation and apoptosis in neuroblastoma. (5/5127)

Inhibition of angiogenesis has been shown to reduce tumor growth, metastasis, and tumor microvascular density in experimental models. To these effects we would now like to add induction of differentiation, based on biological analysis of xenografted human neuroblastoma (SH-SY5Y, WAG rnu/rnu) treated with the angiogenesis inhibitor TNP-470. Treatment with TNP-470 (10 mg/kg s.c., n = 15) reduced the tumor growth by 66% and stereological vascular parameters (Lv, Vv, Sv) by 36-45%. The tumor cell apoptotic fraction increased more than threefold, resulting in a decrease in viable tumor cells by 33%. In contrast, the mean vascular diameter (29 microm) and the mean tumor cell proliferative index (49%) were unaffected. TNP-470-treated tumors exhibited striking chromaffin differentiation of neuroblastoma cells, observed as increased expression of insulin-like growth factor II gene (+88%), tyrosine hydroxylase (+96%), chromogranin A, and cellular processes. Statistical analysis revealed an inverse correlation between differentiation and angiogenesis. It is suggested that by inhibiting angiogenesis, TNP-470 induces metabolic stress, resulting in chromaffin differentiation and apoptosis in neuroblastoma. Such agonal differentiation may be the link between angiostatic therapy and tumor cell apoptosis.  (+info)

Binding partners for the myelin-associated glycoprotein of N2A neuroblastoma cells. (6/5127)

The myelin-associated glycoprotein (MAG) has been proposed to be important for the integrity of myelinated axons. For a better understanding of the interactions involved in the binding of MAG to neuronal axons, we performed this study to identify the binding partners for MAG on neuronal cells. Experiments with glycosylation inhibitors revealed that sialylated N-glycans of glycoproteins represent the major binding sites for MAG on the neuroblastoma cell line N2A. From extracts of [3H]glucosamine-labelled N2A cells several glycoproteins with molecular weights between 20 and 230 kDa were affinity-precipitated using immobilised MAG. The interactions of these proteins with MAG were sialic acid-dependent and specific for MAG.  (+info)

Comparison of two in vitro activation systems for protoxicant organophosphorous esterase inhibitors. (7/5127)

In order to perform in vitro testing of esterase inhibition caused by organophosphorous (OP) protoxicants, simple, reliable methods are needed to convert protoxicants to their esterase-inhibiting forms. Incubation of parathion or chlorpyrifos with 0.05% bromine solution or uninduced rat liver microsomes (RLM) resulted in production of the corresponding oxygen analogs of these OP compounds and markedly increased esterase inhibition in SH-SY5Y human neuroblastoma cells. Neither activation system affected cell viability or the activity of AChE or NTE in the absence of OP compounds. Although parathion and chlorpyrifos were activated by RLM, bromine activation required fewer steps and produced more esterase inhibition for a given concentration of chlorpyrifos. However, RLM activation of OP protoxicants produced metabolites other than oxygen analogs and may, therefore, be more relevant as a surrogate for OP biotransformation in vivo. This methodology makes the use of intact cells for in vitro testing of esterase inhibition caused by protoxicant organophosphate compounds a viable alternative to in vivo tests.  (+info)

MycN sensitizes neuroblastoma cells for drug-induced apoptosis. (8/5127)

Amplification of the MYCN gene is found in a large proportion of neuroblastoma and considered as an adverse prognostic factor. To investigate the effect of ectopic MycN expression on the susceptibility of neuroblastoma cells to cytotoxic drugs we used a human neuroblastoma cell line harboring tetracycline-controlled expression of MycN. Neither conditional expression of MycN alone nor low drug concentrations triggered apoptosis. However, when acting in concert, MycN and cytotoxic drugs efficiently induced cell death. Apoptosis depended on mitochondrial permeability transition and activation of caspases, since the mitochondrion-specific inhibitor bongkrekic acid and the caspase inhibitor zVAD-fmk almost completely abrogated apoptosis. Loss of mitochondrial transmembrane potential and release of cytochrome c from mitochondria preceded activation of caspase-8 and caspase-3 and cleavage of PARP. CD95 expression was upregulated by treatment with cytotoxic drugs, while MycN cooperated with cytotoxic drugs to increase sensitivity to CD95-induced apoptosis and enhancing CD95-L expression. MycN overexpression and cytotoxic drugs also synergized to induce p53 and Bax protein expression, while Bcl-2 and Bcl-X(L) protein levels remained unchanged. Since amplification of MYCN is usually associated with a poor prognosis, these findings suggest that dysfunctions in apoptosis pathways may be a mechanism by which MycN-induced apoptosis of neuroblastoma cells is inhibited.  (+info)

Neuroblastoma is the most common extracranial solid tumor in infants and children. Our lab and others have shown trophic actions of gastrin-releasing peptide (GRP), and its analogue bombesin (BBS), in neuroblastomas. Our lab also found that undifferentiated neuroblastomas express increased levels of GRP receptor (GRPR). Activation of the phosphatidylinositol-3-kinase (PI3K)/Akt pathway, a crucial regulator of cell survival, is associated with poor outcome in neuroblastomas and our lab¡¦s previous work has shown that GRPR regulates the expression of PI3K/Akt pathway components. However, the signaling mechanisms involved in this process are not clearly defined. Therefore, the objective of this project was to determine how GRP/GRPR, by way of PI3K pathway, regulates neuroblastoma growth. \r\n\r\nGRP/BBS treatment rapidly increased phosphorylation of both Akt and GSK-3ƒÒ in neuroblastoma cells. Antagonism or silencing of GRPR attenuated BBS-induced phosphorylation of Akt. PI3K inhibition also ...
Neuroblastoma is the most frequently diagnosed extracranial solid tumour in childhood. While a subset of tumours show spontaneous regression or complete remission following conventional treatment, a substantial number remain resistant to intensive multimodal therapies. Survival rates approaching 40% place high-risk neuroblastoma as one of the greatest challenges in paediatric oncology. This contemporary review provides an update on the diagnosis, risk stratification and management for this enigmatic tumour.. Neuroblastoma is the most common extracranial solid tumour in childhood and the most frequently diagnosed neoplasm during infancy.1 This malignant tumour consists of undifferentiated and/or differentiating cells originating from neural crest-derived sympathoadrenal precursors. Neuroblastoma is often described as enigmatic and unpredictable because of the broad spectrum of clinical behaviour ranging from life-threatening progression despite intensive treatment to complete spontaneous ...

N2 - Retinoic acid (RA) can induce growth arrest and neuronal differentiation of neuroblastoma cells and has been used in clinic for treatment of neuroblastoma. It has been reported that RA induces the expression of several HOXD genes in human neuroblastoma cell lines, but their roles in RA action are largely unknown. The HOXD cluster contains nine genes (HOXD1, HOXD3, HOXD4, and HOXD8-13) that are positioned sequentially from 3′ to 5′, with HOXD1 at the 3′ end and HOXD13 the 5′ end. Here we show that all HOXD genes are induced by RA in the human neuroblastoma BE(2)-C cells, with the genes located at the 3′ end being activated generally earlier than those positioned more ...
eng] Stage 4S neuroblastoma (NB) is a special type of NB found in infants with metastases at diagnosis and is associated with an excellent outcome due to its remarkable capacity to undergo spontaneous regression. As genomics have not been able to explain this intriguing clinical presentation, we here aimed at profiling the DNA methylome of stage 4S NB to better understand this phenomenon. To this purpose, differential methylation analyses between International Neuroblastoma Staging System (INSS) stage 4S, stage 4 and stage 1/2 were performed, using methyl-CpG-binding domain (MBD) sequencing data of 14 stage 4S, 14 stage 4, and 13 stage 1/2 primary NB tumors (all MYCN non-amplified in order not to confound results). Stage 4S-specific hyper- and hypomethylated promoters were determined and further characterized for genomic localization and function by cytogenetic band enrichment, gene set enrichment, transcription factor target enrichment and differential RNA expression analyses. We show that ...

Immunohistochemical double-staining techniques documented that the NSE-positive neoplastic cells also reacted with antibodies to chromogranin and synaptophysin. Notably, ...
TY - JOUR. T1 - IGF-I receptor inhibition combined with rapamycin or temsirolimus inhibits neuroblastoma cell growth. AU - Coulter, Don W.. AU - Blatt, Julie. AU - DErcole, A. Joseph. AU - Moats-Staats, Billie M.. PY - 2008/5/1. Y1 - 2008/5/1. N2 - Background: Neuroblastoma is the third most common solid tumor in children. Treatment continues to be challenging. The pathogenesis of neuroblastoma has been related to expression of the type 1 insulin-like growth factor receptor (IGF1R) and to transcription factor MYC-N amplification. Previous studies have shown that MYC-N expression is disrupted by blockade of the IGF1R with a specific monoclonal antibody, αIR3. Inhibition of IGF1R signaling can be accomplished by other agents, including rapamycin or temsirolimus, which target mTOR (mammalian target of rapamycin). Materials and Methods: BE-2(c) and IMR-32 neuroblastoma cell lines were treated with varying concentrations of αIR3, rapamycin and temsirolimus alone or in combination and the viable ...
A murine monoclonal antibody (monoclonal antibody 126) produced against cultured human neuroblastoma cells (LAN-1) was found to be specifically directed to a disialoganglioside (GD2) antigen preferentially expressed on both cell lines and tissues derived from melanoma and neuroblastoma. In enzyme-linked immunosorbent assays, monoclonal antibody 126 failed to react with leukemic and lymphoblastoid cells as well as with a variety of carcinoma and sarcoma cell lines. Immunohistological analysis by the immunoperoxidase technique revealed strong reactivity of monoclonal antibody 126 with frozen and formaldehyde-fixed neuroblastoma and melanoma tissues. Tissues from patients with glioma or with small cell cancer of the lung showed faint staining, whereas those from individuals with sarcoma, lymphoma, and a variety of other neoplasms proved to be negative. Sera of neuroblastoma patients showed significantly elevated GD2 levels compared to normal children (p , 0.001) and children with other tumors (p , ...
Abstract. Neuroblastoma (NBL) is the most common extracranial solid tumor of childhood, with about 700 new cases of neuroblastoma seen each year in the United States. The 5-year survival rate for children with high-risk NBL is only 50-60%, and this survival rate has not improved over the last 10 years. High-risk patients receive multimodality treatment, including chemotherapy, surgery, radiation therapy, biologic therapy and immunotherapy, all of which are associated with significant morbidity. Recent years have seen many advances in treatment of neuroblastoma, including therapeutic MIBG, immunotherapy, and personalized targeted therapy based on the genetic alterations seen in the tumor. The primary objective of this book is to provide the readers with a comprehensive review of neuroblastoma, from clinical aspects and the currently available treatment to recent advancements and future directions in the field of NBL treatment. The topics and chapters have been compiled keeping in mind a diverse ...
Neuroblastoma is the most common extracranial solid tumor of infancy. It is an embryonal malignancy of the sympathetic nervous system arising from neuroblasts (pluripotent sympathetic cells).
Melphalan could prolong the survival of children with advanced neuroblastoma and is currently used in many high-dose protocols for this patient group (20). The present study shows for the first time that J1, a prodrug of melphalan, is highly active against human neuroblastoma cell lines in vitro and in vivo. The cytotoxic activity of J1 in vitro was found to be superior compared with melphalan, and statistical comparisons also favored J1 in terms of antiproliferative, proapoptotic, and antiangiogenic activity in vivo. These findings are particularly interesting in view of the demonstrated clinical activity of Peptichemio in neuroblastoma (4, 5).. Despite different levels of absolute sensitivity, the seven human neuroblastoma cell lines displayed a similar pattern of sensitivity against the tested drugs (Pearson correlation of log IC50, 0.85-0.99), reflecting the importance of a common cytopathologic origin. The in vitro activity of J1 was, on average, 270-fold that of melphalan, with a range ...
VACCINE DOSING: Vaccine components SJNB-JF-IL2 and SJNB-JF-Lptn will each be dosed at 1x10e7 cells/m2. This will be given in conjunction with an escalating dose of SKNLP vaccine in the phase I portion of this study. In the phase II portion of this study, the same dose of SJNB-JF-IL2 and SJNB-JF-Lptn will be given in conjunction with the highest dose of SKNLP determined in the phase I portion. Vaccination will be administered on an inpatient or outpatient basis. Patient will be notified of which dose of vaccine cells they will receive if enrolled in the study.. Phase I Dose Escalation Component: While the investigators do not suspect that addition of a second irradiated, unmodified neuroblastoma tumor cell line to the previously tested SJNB-JF gene modified cell line will affect the safety profile of the vaccine, as the SKNLP has not been tested previously in vaccine studies, the investigators will perform an abbreviated dose escalation study of the combined vaccine to assess safety. The ...

The neurotrophic actions of pituitary adenylate cyclase-activating polypeptide (PACAP)-38 and leukemia inhibitory factor (LIF) were investigated in human neuroblastoma SH-SY5Y cells. Effects on differentiation were assessed through monitoring morphological changes and Western blot analysis of the expression of neuronal marker proteins. In contrast to PACAP-38, which induced a 5.5-fold increase in the number of neurite-bearing cells, LIF had no significant effect on cell morphology compared to control cells over the 4-day time course. Cells co-treated with PACAP-38+LIF showed a similar increase in neurite-bearing cells compared to those treated with PACAP-38 alone. Cell morphology was similar for PACAP-38-treated and PACAP-38+LIF-co-treated cells, with the formation of bipolar neuron-like cells with long thin neurites, topped by growth cone-like structures and varicosities. SH-SY5Y cells express tyrosine hydroxylase (TH) but only low levels of the neuronal marker proteins: Bcl-2, GAP-43 and ...

Given the challenge in targeting MYCN directly for therapy, we sought to identify MYCN-dependent metabolic vulnerabilities that can be targeted therapeutically. Here, we report that the gene encoding glycine decarboxylase (GLDC), which catalyzes the first and rate-limiting step in glycine breakdown with the production of the one-carbon unit 5,10-methylene-tetrahydrofolate, is a direct transcriptional target of MYCN. As a result, GLDC expression is ...
In the present study, we provide evidence that freshly isolated neuroblastoma cells are susceptible to NK-mediated lysis. More importantly, we show that a key role in the lytic process is played by PVR, a molecule expressed at the tumor cell surface that is recognized by the DNAM-1 receptor. We analyzed highly purified, fresh neuroblastoma cells isolated from bone marrow aspirates (22) . As compared with cultured neuroblastoma cell lines (20) , freshly isolated neuroblasts were generally more resistant to lysis. Remarkably, a certain degree of variability existed among different tumors. In particular, we show that tumor cells displaying maximal susceptibility to lysis were characterized by high surface expression of PVR. This molecule was recently recognized as a ligand for DNAM-1, a surface receptor mediating NK cell activation and tumor cell killing (17) . In line with these findings, we now demonstrate that mAb-mediated disruption of DNAM-1-PVR interactions inhibits NK-mediated killing of ...
Rhabdomyosarcoma (RMS) is the third most common extracranial solid tumor of childhood. Approximately 350 new cases are diagnosed in the United States each year accounting for 3 percent of childhood cancers. RMS is derived from primitive myoblasts and morphologically resembles early stages of prenatal skeletal muscle differentiation. However, a large percentage of RMS tumors occur in locations normally lacking skeletal muscle, with the head and neck, genitourinary tract and retroperitoneum being frequent sites of tumor localization. Development of RMS has been associated with genetic tumor predisposition syndromes including Li-Fraumeni syndrome, neurofibromatosis and Costello syndrome. Childhood RMS is subdivided into two major subtypes, embryonal and alveolar, which have distinct histological features and genetic alterations. Adult RMS is largely a third histological subtype, namely pleomorphic RMS. The alveolar RMS subtype carries a poorer prognosis and is strongly myogenin positive by ...

Purpose: Neuroblastoma is the most common and deadly solid tumor of childhood. Cyclooxygenase-2 is expressed in clinical neuroblastoma tumors and cell lines and inhibitors of this enzyme induce apoptosis in human neuroblastoma cells in vitro and in neuroblastoma xenografts in vivo. We hypothesized that the cyclooxygenase-2- specific inhibitor celecoxib could enhance the cytotoxic effect of chemotherapeutic drugs currently used in neuroblastoma treatment. Furthermore, we investigated if prophylactic treatment with celecoxib could prevent neuroblastoma tumor development in vivo. Experimental Design: Neuroblastoma cell cytotoxicity of chemotherapeutic drugs in combination with celecoxib was examined. In vivo, athymic rats carrying established SH-SY5Y xenografts were treated with celecoxib in combination with irinotecan, doxorubicin or etoposide, or with either drug alone. For prevention studies, rats received celecoxib in the diet, 250 to 2,500 ppm, from the time of tumor cell injection. Results: ...
Neuroblastoma is a childhood extracranial solid tumour that is associated with a number of genetic changes. Included in these genetic alterations are mutations in the kinase domain of the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase (RTK), which have been found in both somatic and familial neuroblastoma. In order to treat patients accordingly requires characterisation of these mutations in terms of their response to ALK tyrosine kinase inhibitors (TKIs). Here, we report the identification and characterisation of two novel neuroblastoma ALK mutations (A1099T and R1464STOP), which we have investigated together with several previously reported but uncharacterised ALK mutations (T1087I, D1091N, T1151M, M1166R, F1174I and A1234T). In order to understand the potential role of these ALK mutations in neuroblastoma progression, we have employed cell culture-based systems together with the model organism Drosophila as a readout for ligand-independent activity. Mutation of ALK at position 1174 (F1174I
Epidemiological and preclinical studies have revealed that omega-3 fatty acids have anticancer properties. We have previously shown that the omega-3 fatty acid docosahexaenoic acid (DHA) induces apoptosis of neuroblastoma cells in vitro by mechanisms involving intracellular peroxidation of DHA by means of 15-lipoxygenase or autoxidation. In our study, the effects of DHA supplementation on neuroblastoma tumor growth in vivo were investigated using two complementary approaches. For the purpose of prevention, DHA as a dietary supplement was fed to athymic rats before the rats were xenografted with human neuroblastoma cells. For therapeutic purposes, athymic rats with established neuroblastoma xenografts were given DHA daily by gavage and tumor growth was monitored. DHA levels in plasma and tumor tissue were analyzed by gas liquid chromatography. DHA delayed neuroblastoma xenograft development and inhibited the growth of established neuroblastoma xenografts in athymic rats. A revised version of the ...
OUTLINE: This is a multicenter study.. Previously collected samples are analyzed to define the genome-wide DNA copy number and allelic status; to define the genome-wide methylation profile of high-risk neuroblastoma cases; to define the genome-wide microRNA expression profile of high-risk neuroblastoma cases; to define the genome-wide RNA expression and relating gene expression to DNA copy number and gene polymorphisms, DNA methylation, and microRNA expression; to resequence three genomes: the neuroblastoma genome, the transcriptome, and the paired constitutional genome; and to characterize the relapsed high-risk neuroblastoma genome and epigenome.. PROJECTED ACCRUAL: A total of 300 tumor samples from patients with high-risk disease, 50 tumor samples from patients with low-risk primary neuroblastoma, and 30 human neuroblastoma-derived cell lines will be accrued for this study. ...
At the ASCO Plenary Session where the HR-NBL1/SIOPEN trial was presented, formal discussant Julie R. Park, MD, of the University of Washington, Seattle, said, Large randomized trials have previously shown that myeloablative therapy improves outcomes in high-risk neuroblastoma, and it is now considered standard of care.. Dr. Park explained that the COJEC regimen used in this study may have contributed to the lower-than-expected 3-year event-free survival in the CEM arm. Previous studies conducted by the Childrens Oncology Group achieved a 3-year event-free survival of 46% with CEM, but those studies used a different induction regimen with lower doses of cisplatin and etoposide and did not include carboplatin.. It is possible that rapid COJEC had a negative interaction with CEM, but not BuMel, she said.. The SIOPEN trial is a great achievement and shows the unity of 20 European nations. This study confirms the importance of myeloablative therapy in a cohort of high-risk neuroblastoma with a ...

N2 - The binding characteristics of [3H]phorbol-12,13-dibutyrate ([3H]PDBu) in mouse neuroblastoma N1E-115 cells were studied. The specific binding of [3H]PDBu to intact cells was saturable and to a homogeneous class of binding sites, with a K(d) of 21 nM. Phorbol 12-myristate-13-acetate and PDBu competed for [3H]PDBu binding whereas 4α-phorbol did not. The binding of [3H]PDBu to the cells was selective, as it was not affected by several agents that interact with various neurotransmitter receptors in N1E-115 cells. The density of the phorbol ester binding site decreased as the cell passage increased, although the K(d) of [3H]PDBu binding remained relatively constant. Upon exposure of the cells to 100 nM PDBu ...
Prenylated Rab acceptor 1 domain family, member 2 (PRAF2) is a novel 19-kDa protein with four transmembrane-spanning domains that belongs to the PRAF protein family. Neuroblastoma (NB) is the most common malignant extracranial solid tumor of childhood that originates in primitive cells of the developing sympathetic nervous system. We investigated the correlation of PRAF2 mRNA expression to NB clinical and genetic parameters using Affymetrix expression analysis of a series of 88 NB tumors and examined the functional role of PRAF2 in an NB cell line using RNA interference. We found that high PRAF2 expression is significantly correlated to several unfavorable NB characteristics: MYCN amplification, high age at diagnosis, poor outcome and high INSS stage. The shRNA-mediated PRAF2 downregulation in the SK-N-SH NB cell line resulted in decreased cellular proliferation, migration and matrix-attachment. These findings were confirmed in NB patient tumor samples, where high PRAF2 expression is ...

Recently, we showed that high T-cell infiltration correlates with favorable clinical outcome in high-risk neuroblastoma patients (13). Herein, we demonstrate that TILs express PD-1 and LAG3, two negative regulators of T-cell function (33), and that neuroblastoma cells either express PD-L1 or HLA-I. According to the density of PD-L1+ and HLA-I+ tumor cells and regardless of infiltrating T-cell density, MYCN amplification status, INSS stage, and age at diagnosis, we could distinguish two PD-L1/HLA-I combinations: one associated with good prognosis (high HLA-I and low or no PD-L1) and the other associated with poor prognosis (low HLA-I and high or no PD-L1). Our findings provide a proof of principle that PD-L1 in combination with HLA-I expression may serve as a biomarker in neuroblastoma, although this has to be further confirmed by a prospective study with a larger number of samples.. Of note, a good PD-L1/HLA-I combination was also associated with favorable clinical outcome in intrahepatic ...
July 5, 2011 - A new treatment option may soon be available for children with neuroblastoma, according to research published in the July issue of The Journal of Nuclear Medicine. The study tested the principle that combined positron emission tomography and X-ray computed tomography (PET/CT) may be used to select children with primary refractory or relapsed high-risk neuroblastoma for treatment with a molecular radiotherapy known as 177Lu-DOTATATE. This therapeutic option was found to be a viable option for children with neuroblastomas. Neuroblastoma is a cancerous tumor that develops from nerve tissue in infants and children. Accounting for six to 10 percent of all childhood cancers, it does not always follow the same pattern, with some patients regressing spontaneously and other progressing, despite aggressive therapy. The long-term survival rate for neuroblastoma is below 40 percent. We know that peptide receptor radionuclide therapy in adults with somatostatin-positive neuroendocrine tumors ...
Neuroblastoma, a neoplasm of the sympathetic nervous system, is the second most common extracranial malignant tumor of childhood and the most common solid tumor of infancy [1]. The outcome of children with neuroblastoma is variable when the disease is categorized by age, stage, and clinical characteristics [2,3].. Efforts to improve the outcome of patients with neuroblastoma have focused on identification of risk groups based on clinical and biologic variables as well as intensification of therapy for high-risk cases [4]. Genetic characteristics of neuroblastoma can be divided into those with near-diploid nuclear DNA characterized by the presence of genetic aberration such as MYCN amplification,17q gain, and chromosome losses, and near-triploid tumors characterized by whole chromosome gains and losses without structural genetic aberrations, meta-analysis of prognostic markers show that MYCN amplification and DNA ploidy are of prognostic significance and currently are used along clinical factors ...
The nature of the signal transducing the change in cell volume to the activation of osmolyte efflux pathways for RVD in osmotically swollen cells is not clear. Two major models have been proposed, one involving Ca2+ as an intracellular second messenger and the other in which RVD is mediated through Ca2+-independent mechanisms. According to the first model, cell swelling causes an increase in cytosolic Ca2+ that activates volume regulatory mechanisms. The increase in [Ca2+]i may result from Ca2+ influx, via plasma membrane channels (Christensen, 1987), or Ca2+ release from intracellular stores (McCarty and ONeil, 1992; Wu et al., 1997). The proposed effectors are mostly Ca2+-activated cation and anion channels and carriers. This model has been widely accepted as a paradigm for the involvement of Ca2+ as a transducing signal for RVD. Nevertheless, the existing evidence backing up this model is often weak and fragmentary, and the comprehensive analysis necessary to establish an active role of ...

We sought to establish whether transplanted HT4 cells expressed class I major histocompatibility to complex (MHC) antigens, a partial requirement for recognition by cytotoxic T lymphocytes (CTL), and thus be susceptible to xenograft rejection. Differentiated HT4 cells expressed marginally detectable ...
Purpose: Neuroblastoma is the most common extracranial solid cancer type in childhood and high-risk patients have poor prognosis despite aggressive multimodal treatment. Neuroblastoma-driven inflammation contributes to the induction of suppressive myeloid cells that hamper efficient anti-tumor immune responses. Therefore, we sought to enhance anti-tumor immunity by removing immunosuppression mediated by myeloid cells. Experimental Design: The prognostic values of myeloid cells are demonstrated by analyzing genomic datasets of neuroblastoma patients. The impact of tumor-derived factors on myelopoiesis and local induction of suppressive myeloid cells are dissected by in vitro culture models using freshly isolated human CD34+ hematopoietic stem cells, primary human monocytes and murine bone marrow cells. To test the therapeutic efficacy of BLZ945 as a monotherapy or in combination with checkpoint inhibitors, we employed a transgenic murine model (TH-MYCN) that develops aggressive spontaneous ...

A third neuroblastoma cell line, NLF, was less sensitive to CDDP, i.e., exhibited a significant decrease in cell viability only after 48h treatment with 10 M CDDP (< 0.001; Supplementary Physique 1). Physique 1 Cell survival and apoptosis in neuroblastoma cells following CDDP or TOPO treatment TOPO (0.1 nM to 1 1 M) demonstrated a stronger cytotoxic effect compared to CDDP in all neuroblastoma cell lines tested and cell viability was significantly reduced in SH-SY5Y cell after 24 h, 48 h and 72 h of exposure (Determine 1Ai). The cytotoxic effects of TOPO were stronger in IMR-32 cells as compared with ...

As part of a tumour growth inhibition study, SK-N-SH xenografts were generated in BALB/c nu/nu mice. Mice (n = 8) were placed in a printed MR- and CT-compatible plastic cradle, imaged using a 4.7-T MRI scanner and then transferred to a small animal radiation research platform (SARRP) irradiator with on-board CBCT. MRI/CBCT co-registration was performed to enable RT planning using the soft-tissue contrast afforded by MRI prior to delivery of RT (5 Gy). Tumour response was assessed by serial MRI and calliper measurements.. ...
Neuroblastomas express increased levels of gastrin-releasing peptide receptor (GRP-R). However, the exact molecular mechanisms involved in GRP-R-mediated cell signaling in neuroblastoma growth and metastasis are unknown. Here, we report that focal adhesion kinase (FAK), as a critical downstream target of GRP-R, is an important regulator of neuroblastoma tumorigenicity. We found that FAK expression correlates with GRP-R expression in human neuroblastoma sections and cell lines. GRP-R overexpression in SK-N-SH cells increased FAK, integrin α3 and β1 expressions and cell migration. These cells demonstrated flatter cell morphology with broad lamellae, in which intense FAK expression was localized to the leading edges of lamellipodia. Interestingly, FAK activation was, in part, dependent on integrin α3 and β1 expression. Conversely, GRP-R silencing decreased FAK as well as Mycn levels in BE(2)-C cells, which displayed a denser cellular morphology. Importantly, rescue experiments in GRP-R silenced BE(2)-C
Human neuroblastoma (NB) cell lines may present with either one of the so-called S-and N-subtypes. We have previously reported a strong correlation between protein expression levels of vimentin, an S-subtype marker, and the p21Waf1 cyclin-dependent kinase inhibitor. We here investigated whether this correlation extend to the mRNA level in NB cell lines as well as in patients tumors. We also further explored the relationship between expression of vimentin and p21, by asking whether vimentin could regulate p21 expression. Vimentin and p21 mRNA levels in NB cell lines as well as in patients tumors (n = 77) were quantified using Q-PCR. Q-PCR data obtained from tumors of high risk NB patients (n = 40) were analyzed in relation with the overall survival using the Log-rank Kaplan-Meier estimation. siRNA-mediated depletion or overexpression of vimentin in highly or low expressing vimentin cell lines, respectively, followed by protein expression and promoter activation assays were used to assess the role of

Neuroblastoma x glioma hybrid NG108-15 cells endogenously express at least three receptors which activate adenylate cyclase via the intermediacy of the stimulatory G-protein, Gs. Sustained exposure of the cells to agonists at the IP prostanoid receptor results in a substantial decrease in cellular levels of the alpha-subunit of Gs (Gs alpha) [McKenzie and Milligan (1990) J. Biol. Chem. 265, 17084-17093; Adie, Mullaney, McKenzie and Milligan (1992) Biochem J. 285, 529-536]. By contrast, equivalent treatments of the cells with agonists at either the A2 adenosine receptor or the secretin receptor have no measurable effect on cellular amounts of Gs alpha. To examine whether this is a feature specific to the IP prostanoid receptor or is related to the level of expression of the individual receptors, NG108-15 cells were transfected with a construct containing a human beta 2-adrenoceptor cDNA under the control of the beta-actin promoter. Two clones of these cells were examined in detail, beta N22, ...

Diaminofluorescein (DAF) was applied for the assessment of RNS production in isolated mouse brain, heart and liver mitochondria and also in a cultured neuroblastoma cell line by confocal microscopy and flow cytometry. Mitochondria produced RNS, which was inhibited by catalysts of peroxynitrite decomposition but not by nitric oxide (NO) synthase inhibitors. Disrupting the organelles or withdrawing respiratory substrates markedly reduced RNS production. Inhibition of complex I abolished the DAF signal, which ...
undecylenic acid.. Now scientists from Poland have done an experiment to improve the efficiency of neuroprotective effects of undecylenic acid by targeting it using polyelectrolyte coated nanocapsules. Core shell nanocapsules were prepared using nanoemulsification and the layer by layer technique. The average size of nanocapsules was around 80nm and the concentration was 2.5×1010 particles/ml. The nanocapsules were coated with either polycation or polyanion layers.. Biocompatibility of the synthesized nanocarriers was evaluated in SH-SY5Y human neuroblastoma cell line using cell viability/toxicity assays.. Results showed that nanocapsules coated with PLL and PGA were non-toxic to the human neuroblastoma cell line, thereby showing its potential to be used as a carrier of undecylenic acid. Further research showed that nanoencapsulated form of undecylenic acid was biocompatible and more effective against staurosporine-induced damage in lower concentrations than those of the same drug added ...
Its primary physiological function is unclear. Has cytoprotective activity against internal or environmental stresses. May play a role in neuronal development and synaptic plasticity. May be required for neuronal myelin sheath maintenance. May play a role in iron uptake and iron homeostasis. Soluble oligomers are toxic to cultured neuroblastoma cells and induce apoptosis (in vitro). Association with GPC1 (via its heparan sulfate chains) targets PRNP to lipid rafts. Also provides Cu(2+) or ZN(2+) for the ascorbate-mediated GPC1 deaminase degradation of its heparan sulfate side chains (By similarity).

In most mammalian cells, regulatory volume decrease (RVD) is mediated by swelling-activated Cl(-) and K(+) channels. Previous studies in the human neuroblastoma cell line CHP-100 have demonstrated that exposure to hypoosmotic solutions activates Cl(-) channels which are sensitive to Ca(2+). Whether a Ca(2+)-dependent K(+) conductance is activated after cell swelling was investigated in the present studies. Reducing the extracellular osmolarity from 290 to 190 mOsm/kg H(2)O rapidly activated 86Rb effluxes. Hypoosmotic stress also increased cytosolic Ca(2+) in fura-2 loaded cells.
The role of reactive oxygen species (ROS) in the regulation of signal transduction processes has been well established in many cell types and recently the fine tuning of redox signalling in neurons received increasing attention. With regard to this, the involvement of NADPH oxidase (NOX) in neuronal pathophysiology has been proposed but deserves more investigation. In the present study, we used SH-SY5Y neuroblastoma cells to analyse the role of NADPH oxidase in retinoic acid (RA)-induced differentiation, pointing out the involvement of protein kinase C (PKC) delta in the activation of NOX. Retinoic acid induces neuronal differentiation as revealed by the increased expression of MAP2, the decreased cell doubling rate, and the gain in neuronal morphological features and these events are accompanied by the increased expression level of PKC delta and p67(phox), one of the components of NADPH oxidase. Using DPI to inhibit NOX activity we show that retinoic acid acts through this enzyme to induce ...
Neuroblastoma (NB) is a common childhood malignant tumor of the neural crest-derived sympathetic nervous system. In NB the frequent loss of heterozygosity (LOH) on chromosome 1p raises the possibility that this region contains tumor-suppressor genes whose inactivation contributes to tumorigenesis. T …
Publisher: University of Delaware. Date Issued: 2014. Abstract: This study was designed to examine the mechanism by which inhibition of lysosomal proteases causes cell death in neuroblastoma. The major lysosomal proteases are two cysteine proteases, cathepsins B and L, and an aspartic protease, cathepsin D. Inhibition of these three proteases was found to cause cellular accumulation of fragments of the IGF-1 receptor. The fragments were located in dense organelles that were characterized as autophagosomes. This novel discovery provides the first clear link between lysosIGF-1omal function, autophagy and IGF-1 mediated cell proliferation. It provides a mechanistic explanation for enhanced cytotoxicity of chemotherpautic agents when combined with inhibitors of lysosomal function and autophagy. A more in depth analysis of the IGF1 signaling pathway revealed that the MAPK pathway was particularly impaired in inhibitor treated cells, while the PKB cell survival pathway remained functional. It was ...

The cell signaling docking protein p130cas became tyrosine-phosphorylated in SH-SY5Y human neuroblastoma cells during induced differentiation with 12-O-tetradecanoylphorbol-13-acetate (TPA) and serum or a combination of basic fibroblast growth factor (bFGF) and insulin-like growth factor-I (IGF-I). The differentiating cells develop a neuronal phenotype with neurites and growth cones and sustained activation of protein kinase C (PKC) and pp60c-src. The TPA-induced p130cas phosphorylation increased within 5 min of stimulation and persisted for at least 4 days, whereas bFGF/IGF-I-induced p130cas phosphorylation was biphasic. However, the increase in tyrosine phosphorylation of p130cas was not restricted to differentiation inducing stimuli. The phosphorylation was blocked by the specific PKC inhibitor GF 109203X, and transient transfection with active PKC-epsilon induced p130cas tyrosine phosphorylation. pp60c-src, known to directly phosphorylate p130cas in other cell systems, was not activated ...
Hello! The term neuroblastoma is commonly used to refer to a spectrum of neuroblastic tumors (including neuroblastomas, ganglioneuroblastomas, and ganglioneuromas) that arise from primitive sympathetic ganglion cells and, like paragangliomas and pheochromocytomas, have the capacity to synthesize and secrete catecholamines..

NEUROBLASTOMA IS THE MOST COMMON, HIGHLY MALIGNANT, SOLID TUMOR FOUND IN CHILDREN. WHEN DIAGNOSED IN ASYMPTOMATIC CHILDREN, THE PROGNOSIS IS OFTEN POOR. HOWEVER, WHEN DETECTED IN ASYMPTOMATIC CHILDREN AS A RESULT OF THE URINE TUMOR MARKERS SCREENING PROGRAM, THE NEUROBLASTOMA IS USUALLY LOCALIZED AND TREATABLE, AND THE OUTCOME IS FAVORABLE. MOST NEUROBLASTOMA CASES HAVE HIGH URINE LEVELS OF HOMOVANILLIC ACID (HVA) AND/OR VANILLYLMANDELIC ACID (VMA). THESE TWO TUMOR MARKERS CAN BE MEASURED ACCURATELY AND PRECISELY BY HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY OR GAS CHROMATOGRAPHY, BUT THESE PROCEDURES ARE NOT PRACTICAL FOR DETERMINING HVA AND VMA IN LARGE NUMBERS OF URINE SPECIMENS. THIS PROJECT WILL DEVELOP A UNIQUE ENZYME IMMUNOASSAY (EIA) METHOD WITH MONOCLONAL ANTIBODIES TO DETECT HVA AND VMA. THE TECHNIQUE WILL BE AUTOMATED, COMPUTERIZED, AND COST EFFECTIVE, PERMITTING THE SCREENING OF A LARGE NUMBER OF SPECIMENS.

A modified UHPLC-HRMS method for simultaneous quantification of eight flavonoids from the aerial parts of the wild spinach (Chenopodium bonus-henricus L.) was re-validated for specificity, the limit of detection and quantitation limit, linearity, accuracy, and precision. The glycosides of spinacetin (Chbhnf-04, Chbhnf-06, and Chbhnf-08) and patuletin (Chbhnf-01) were the predominant compounds. The total amount of assayed flavonoids from the aerial parts of a title plant was estimated to be 1.82% and 1.4% in two different populations from Vitosha Mountain (Bulgaria). The neuroprotective properties of compounds Chbhnf-02, Chbhnf-04, Chbhnf-06, Chbhnf-07, Chbhnf-08 were further assessed using a model of H2O2-induced oxidative stress on human neuroblastoma SH-SY5Y cells. All tested flavonoids demonstrated statistically significant neuroprotective activity close to that of silibinin. Patuletin (Chbhnf-07) and spinacetin (Chbhnf-08) triglycosides showed the most protective effects at the lowest concentration

BACKGROUND: Although disease remission can frequently be achieved for patients with neuroblastoma, relapse is common. The cancer stem cell theory suggests that rare tumorigenic cells, resistant to conventional therapy, are responsible for relapse. If true for neuroblastoma, improved cure rates may only be achieved via identification and therapeutic targeting of the neuroblastoma tumor initiating cell. Based on cues from normal stem cells, evidence for tumor populating progenitor cells has been found in a variety of cancers. METHODOLOGY/PRINCIPAL FINDINGS: Four of eight human neuroblastoma cell lines formed tumorspheres in neural stem cell media, and all contained some cells that expressed neurogenic stem cell markers including CD133, ABCG2, and nestin. Three lines tested could be induced into multi-lineage differentiation. LA-N-5 spheres were further studied and showed a verapamil-sensitive side population, relative resistance to doxorubicin, and CD133+ cells showed increased sphere formation ...
Chemotherapy is one of the major modalities in treating cancers. However, its effectiveness is limited by the acquisition of multidrug resistance (MDR). Several mechanisms could explain the up-regulation of MDR genes/proteins in cancer after chemotherapy. It is known that cancer stem cells (CSCs) play a role as master regulators. Therefore, understanding the mechanisms that regulate some traits of CSCs may help design efficient strategies to overcome chemoresistance. Different CSC phenotypes have been identified, including those found in some pediatric malignancies. As solid tumors in children significantly differ from those observed in adults, this review aims at providing an overview of the mechanistic relationship between MDR and CSCs in common solid tumors, and, in particular, focuses on clinical as well as experimental evidence of the relations between CSCs and MDR in neuroblastoma and hepatoblastoma. Finally, some novel approaches, such as concomitant targeting of multiple key transcription
In this study, an efficient purification method for the polyphenols of Pinus koraiensis pinecone (PPP) has been developed. AB-8 resin was verified to offer good adsorption and desorption ratio for PPP. Response surface methodology (RSM) indicated that the optimized purification parameters for PPP were 1.70 mg GAE/mL phenolic sample concentration, 22.00 mL sample volume, and 63.00% ethanol concentration. Under these conditions, the experimental purity of PPP was 27.93 ± 0.14% (n = 3), which matched well with the predicted purity of 28.17%. Next, the antiproliferative effects of PPP on seven cancer cell lines, including A375 (human skin melanoma cancer cell line), A549 (human lung cancer cell line), SH-SY5Y (human neuroblastoma cell line), LOVO (human colon cancer stem cell line), MCF-7 (human breast cancer cell line), HeLa (human cervical cancer line), and HT29 (human colon cancer line), were examined by MTT assays. The results indicated that PPP had the highest capacity for inhibiting LOVO cells growth
SHSY5Y and HeLa cells were transiently transfected with scRNA (SHSY5Y/scRNA and HeLa/scRNA) or -Syn-siRNA (SHSY5Y/-Syn-siRNA and HeLa/-Syn-siRNA) for 48 h. in malignancy cells. RESULTS TTP overexpression promotes an elongation of mitochondria Previously, we reported that overexpression of TTP suppresses cellular proliferation [46, 47, 50] and induces a change in cell morphology from a mesenchymal shape to an epithelial shape [51]. Here we assessed whether TTP overexpression modifies mitochondrial morphology. To test this, SHSY5Y neuroblastoma cells and HeLa cervical carcinoma cells were transiently transfected with pcDNA6/V5-TTP (SHSY5Y/TTP and HeLa/TTP) or a control pcDNA6/V5 (SHSY5Y/pcDNA and HeLa/pcDNA) vector. After confirming the overexpression of TTP by RT-PCR and western blot analysis (Number ?(Figure1A),1A), mitochondria in the cells were stained with Mitotracker. Confocal microscopic imaging of mitochondria showed that TTP overexpression advertised the elongation of the mitochondrial ...

This receptor is expressed by activated, but not by resting, T and B cells. TRAF2 and TRAF5 can interact with this receptor, and mediate the signal transduction that leads to the activation of NF-kappaB.

Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.[5] ...
The NCLs present with progressive loss of visual function and neurodevelopmental decline, seizure, myoclonic jerks and premature death. The CTSD gene is one of the identified eight genes the deficiency of which is responsible for NCLs.[10] It has been reported that a homozygous single nucleotide duplication in exon 6 could alter the reading frame and causes a premature stop codon at position 255. Over-expression of cathepsin D stimulates tumorigenicity and metastasis as well as initiation of tumor apoptosis. This protease has been regarded an independent marker of poor prognosis in breast cancer being correlated with the incidence of clinical metastasis.[21][22] Knock-out of CTSD gene would cause intestinal necrosis and hemorrhage and increase apoptosis in thymus, indicating that cathepsin D is required in certain epithelial cells for tissue remodeling and renewal.[9] It is also reported that there might be a strong effect for CTSD genotype on Alzheimer disease risk in male.[23] Cathepsin D ...
Pain may be relieved by nonsteroidal anti-inflammatory drugs.. Treatment varies based on the health of the patient. If he/she is otherwise healthy and is not significantly bothered by the pain, the tumor is treated symptomatically with anti-inflammatories. If this therapy fails or the location of the tumor could lead to growth disturbances, scoliosis, or osteoarthritis, surgical or percutaneous ablation may be considered.[10] If surgery is preferred, the individual may be referred to a podiatrist or an orthopedic surgeon to perform the procedure. Post-surgery therapy and strengthening may be needed, depending on the tumor location and health of the individual. While shown to be effective, surgical resection has many potential complications, including difficult intraoperative identification of the tumor, local recurrence from incomplete resection, and resection of weight bearing bone that can necessitate prolonged hospital stays and complicate recovery.[11]. Recently, CT guided radiofrequency ...
Clinical features of CRPS have been found to be inflammation resulting from the release of certain pro-inflammatory chemical signals from the nerves, sensitized nerve receptors that send pain signals to the brain, dysfunction of the local blood vessels' ability to constrict and dilate appropriately, and maladaptive neuroplasticity.[11] The signs and symptoms of CRPS will usually manifest near the injury site. The most common symptoms are extreme pain including burning, stabbing, grinding, and throbbing. The pain is out of proportion to the severity of the initial injury.[6] Moving or touching the limb is often intolerable. With diagnosis of either CRPS I or II, patients may develop burning pain and allodynia (pain to non-noxious stimuli). Both syndromes are also characterized by autonomic dysfunction, which presents with localized temperature changes, cyanosis, and/or edema. The patient may also experience localized swelling; extreme sensitivity to non-painful things such as wind, water, noise ...

... was first described in 1976,[16] first purified in 1977,[17] the gene was cloned in 1989,[6] and the first knockout mouse was created in 1996.[18] The function of desmin has been deduced through studies in knockout mice. Desmin is one of the earliest protein markers for muscle tissue in embryogenesis as it is detected in the somites.[12] Although it is present early in the development of muscle cells, it is only expressed at low levels, and increases as the cell nears terminal differentiation. A similar protein, vimentin, is present in higher amounts during embryogenesis while desmin is present in higher amounts after differentiation. This suggests that there may be some interaction between the two in determining muscle cell differentiation. However desmin knockout mice develop normally and only experience defects later in life.[13] Since desmin is expressed at a low level during differentiation another protein may be able to compensate for desmin's function early in development but not ...
