Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Study on the metastatic mechanisms of human giant-cell lung carcinoma comparison between the strains C and D. (1/25)

The biologic characteristics of the two human giant-cell lung carcinoma strains with high (strain D) and low metastatic potential (strain C) were studied, including karyotype of chromosome, intracellular free calcium ([Ca2+]i), morphologic changes of cell surface and the expression of nm23-H1, p53, ras, c-myc, c-erbB2, bcl-2 genes and PCNA. The correlation between different biologic features and the metastatic potential of the two strains was analyzed. We found: 1) Both strains had the karyotypic abnormality of -13, -14, -15, +20, +21 with seven same marker chromosomes. Only strain D had the karyotypic abnormality of +7, -17, -18, +X, 7p+; 2) [Ca2+]i of the strain C (984.7 +/- 573.8) and D (517.6 +/- 216.6) was significantly different (p < 0.05). The amplitude of intracellular calcium oscillations of strain C was lower than the one of strain D; 3) strain C had more villous-like protrusions on the cell surface, whereas strain D had more bubble-like protrusions; 4) The expression of nm23-H1 and p53 protein of strain C was all higher than that of strain D. The expression of PCNA of strain C was lower than strain D; 5) nm23-H1 mRNA levels of strain C was lower than that of strain D. We consider that the karyotype of chromosomes, intracellular free calcium, the structure of cell membrane and the expression of nm23-H1 gene, p53 gene, PCNA could be closely related to the metastatic potential of human giant-cell lung carcinoma. They could be used as the sign for judging whether the tumor will metastasize in clinical practice as well as in judging the prognoses of patients.  (+info)

Effect of interleukin-6 on the growth of human lung cancer cell line. (2/25)

OBJECTIVE: To investigate the effect of interleukin-6 (IL-6) on the growth of human lung cancer in vivo as well as in vitro. METHODS: To examine the mRNA level of IL-6 receptor (IL-6R) in high-metastatic human lung giant cell carcinoma cell line PG by means of reverse transcription polymerase chain reaction (RT-PCR). To assess the existence of IL-6 receptor complex (including IL-6R and gp130) with the treatment of PG cells by use of recombinant human IL-6 (rhIL-6), recombinant human oncostatin M (rhOSM), and recombinant human leukemia inhibitory factor (rhLIF), respectively. To detect the expression of IL-6 by Northern blotting hybridization and bioactive assay. To identify the effect of IL-6 secreted by PG cells by use of IL-6 and IL-6R antisense oligodeoxynucleotides (ODNs), and specific neutralizing antibody to IL-6. To document the influence of IL-6 on PG cells growth in vivo through the strategy of the transfection of expression vector inserted antisense IL-6 cDNA. RESULTS: RT-PCR analysis revealed that PG cells expressed IL-6R mRNA. Any one of the recombinant cytokine IL-6, OSM and LIF stimulated the growth of PG cells in vitro in a concentration-dependent manner. These results demonstrated IL-6 receptor complex exist in PG cells. At the same time, PG cells expressed IL-6 mRNA and secreted bioactive IL-6. Both IL-6 antisense ODNs and IL-6R ODNs inhibited PG cells proliferation. Treatment of PG cells with IL-6 antibodies reduced the growth of PG cells in vitro. PG cells transfected with IL-6 antisense expression vector showed a decreased growth in nude mice. CONCLUSION: IL-6 functions as an autocrine growth stimulator for PG cells in vivo as well as in vitro.  (+info)

Pleomorphic carcinoma: report of a case with massive pleural effusion and asbestos particles. (3/25)

Pleomorphic (spindle/giant cell) carcinoma (PC) is one subset of large cell carcinoma. It is well known that PC patients have a poor survival rate. This report describes a 68-year-old man with PC. The patient's tumor had a massive pleural effusion. A left lower lobectomy and partial resection of the left diaphragm, peritoneum, and parietal pleura were performed to remove the tumor. Numerous asbestos particles were found in the left lower lobe. This is the first reported case of PC which may have been caused by asbestos particles. Further investigation is needed into whether asbestos exposure causes PC.  (+info)

Effective asymmetry in gap junctional intercellular communication between populations of human normal lung fibroblasts and lung carcinoma cells. (4/25)

The dysfunction of homologous and/or heterologous gap junctional intercellular communication (GJIC) has been implicated in tumorigenesis of many kinds of cells. Here we have characterized GJIC and the expression of connexins in six human lung carcinoma cell lines and normal lung fibroblasts (HLF). Compared with HLF, all the carcinoma cells showed reduced or little homologous GJIC. They expressed remarkably reduced connexin(Cx)43 mRNA and variable levels of Cx45 mRNA, but neither Cx43 nor Cx45 protein could be detected. However, using a preloading assay, transfer of calcein was observed between donor HLF cells and first order neighboring recipient tumor cells (recipient cells in 1000-fold excess). Transfer from tumor to HLF cells under the same conditions was not seen, although increasing the ratio of donor tumor cells to recipient HLF cells and plating the cells at low density did reveal weak transfer from tumor cells to HLF. Transfection of Cx43 into giant cell carcinoma PG cells increased homologous communication and eliminated the rectifying behavior of heterologous communication. This indicates that the apparent rectification of dye transfer between normal and tumor cells was a product of low rates of heterologous transfer linked to (i) rapid dilution of the dye to below detectable limits through a very well coupled cell population (tumor to HLF) and (ii) concentration of dye in immediate neighbors in a poorly coupled cell population (HLF to tumor cells). These results suggest that the coupling levels may need to exceed a certain threshold to allow propagation of signals over a sufficient distance to affect behavior of a cell population. We propose that the relative rates of heterologous and homologous coupling of cell populations and the 'pool size' of shared metabolites in tumor cells and the surrounding normal tissue are likely to be very important in the regulation of their growth.  (+info)

Clinicopathological features of giant cell carcinoma of the pancreas. (5/25)

BACKGROUND: Giant cell carcinoma of the pancreas (GCCP) as a tumor of high malignancy, large size, and inflammatory reaction occupies 2.1%-12.8% of all cases of pancreatic malignancies. This study was to analyze cases of GCCP collected in 8 years at our hospital in an attempt to describe some features of GCCP in Chinese people. METHODS: The clinicopathological features of 19 patients who had been pathologically diagnosed as having GCCP from 1021 patients with pancreatic malignancies collected by Pancreatic Disease Research Group (PDRG) of Changhai Hospital were retrospectively analyzed compared with those of 96 patients with common pancreatic carcinoma (PC) who were randomly selected from 1002 patients with pancreatic carcinoma. The differences of location, clinical symptoms, imagings, laboratory test, operation and the prognosis of these two groups were defined. RESULTS: Tumors in the head of the pancreas were found in 8 patients (42.1%), and those in the body or tail of the pancreas in 11 (57.9%). The initial symptom was abdominal pain in most patients (57.9%). Abdominal pain (73.7%), dyspepsia (63.2%), weight loss (36.8%) but jaundice were common at the time of diagnosis. The abnormal rates of routine laboratory tests in the GCCP group were lower than those in the common PC group. The assay of tumor markers between the groups of GCCP and common PC was approximately the same. The sensitivity and accuracy of ultrasonography, spiral computed tomography and magnetic resonance imaging were considerably high. Large carcinoma in stage IV was seen in 9 patients or 47.4% of the GCCP group, a rate higher than that in the common PC group. Osteoid formation was found microscopically in some patients, and poorly differentiated tumor cells were found in most patients. The 1-year survival rate was 17.6%, which was lower than that in the common PC group. CONCLUSION: The clinicopathological features of GCCP are different from those of common PC. Imaging tests can be used together with the assay of tumor markers to diagnose GCCP as early as possible and to improve the prognosis of GCCP patients.  (+info)

Structure analysis and expressions of a novel tetratransmembrane protein, lysosoma-associated protein transmembrane 4 beta associated with hepatocellular carcinoma. (6/25)

AIM: To analyze the structure and expressions of the protein encoded by an HCC-associated novel gene, lysosome-associated protein transmembrane 4 beta (LAPTM4B). METHODS: Primary structure and fundamental characteristics of LAPTM4B protein were analysed with bioinformatics. Expressions of LAPTM4B in HCC tissues and various cell lines were detected using polyclonal antibodies and Western blot. RESULTS: LAPTM4B encoded two isoforms of proteins with molecular masses 35-ku and 24-ku, respectively. The expression level of LAPTM4B-35 protein in HCC tissues was dramatically upregulated and related to the differentiation status of HCC tissues, and it was also high in some cancer cell lines. Computer analysis showed LAPTM4B was an integral membrane protein with four transmembrane domains. LAPTM4B showed relatively high homology to LAPTM4A and LAPTM5 in various species. CONCLUSION: LAPTM4B gene encoded two isoforms of tetratransmembrane proteins, LAPTM4B-35 and LAPTM4B-24. The expression of LAPTM4B-35 protein is upregulated and associated with poor differentiation in human HCC tissues, and also at high levels in some cancer cell lines. LAPTM4B is an original and conserved protein.  (+info)

Combined osteoclastic giant cell and pleomorphic giant cell tumor of the pancreas: a rarity. An immunohistochemical analysis and review of the literature. (7/25)

CONTEXT: The combination of an osteoclastic giant cell tumor and a pleomorphic giant cell carcinoma of the pancreas is distinctly unusual and is associated with an adverse outcome. The origin of these two components within a tumor has long been debated based on the immunohistochemical and ultra-structural analysis. CASE REPORT: Herein we describe a tumor with amalgamation of these two distinct histomorphologies along with a minute focus of well-differentiated ductal adenocarcinoma (on multiple sections) in a 50-year male. On immunohistochemical analysis, osteoclastic giant cells were reactive for CD68 and vimentin confirming histiocytic/mesenchymal derivation whereas pleomorphic giant cells and mononuclear cells were reactive for cytokeratin which proved their epithelial nature. CONCLUSIONS: Although the present case had an equal proportion of both components, it is very important to correctly assess the predominant histology since osteoclastic giant cell tumor has a better prognosis as compared to the more aggressive pleomorphic giant cell carcinoma component.  (+info)

Aggressive giant cell tumour of bone. (8/25)

INTRODUCTION: The surgical treatment of Stage III or aggressive giant cell tumour of the bone, whether to perform intralesional or en-bloc resection, remains controversial. The aim of this study is to identify the effectiveness of en-bloc resection for local control and final oncological outcome of the disease. METHODS: The data of 20 consecutive patients with Stage III giant cell tumour were retrospectively reviewed to determine the local control and oncological outcome after treatment with wide resection. RESULTS: The majority of the patients presented late with mean duration of symptoms of 24 months, and four patients presented with recurrences. All patients were treated with wide resection except for two patients who underwent ablative surgery due to major neurovascular involvement. Ten patients required free vascularised tissue transfer to cover massive soft tissue defect. Local recurrence occurred in one patient who was again treated with wide resection and vascularised flap. Six patients had pulmonary metastases. Two patients with resectable disease were treated with thoracoscopic surgery and they remained disease-free 36 months after surgery. Two patients with multiple lung metastases were treated with chemotherapy and the disease remained non-progressive. The remaining two patients who refused chemotherapy showed radiological progression, and one succumbed to the disease with massive haemoptysis. CONCLUSION: Aggressive giant cell tumour of bone should be treated with wide resection for better local control, and treatment of pulmonary metastases is mandatory for overall prognosis.  (+info)

Background: Undiffrentiated pleomorphic sarcoma of vulva with osteoclastic giant cells is a diagnosis of exclusion. It is an exceptionally uncommon diagnostic finding which was eventually diagnosed in our institute and this required a methodical clinical approach and extensive immunohistochemical markers to rule out other probable diagnostic possibilities at this site. The quick diagnostic approach at our institute was ensued by operation. Case Report: 53 years old female presented with vulval growth to our institute. Incision biopsy was performed as a routine procedure. Biopsy showed atypical spindle cells with few cells showing rhabdoid morphology and osteoclast like giant cells were also present. Histological findings with aid of immunohistochemistry led to the diagnosis of undifferentiated pleomorphic sarcoma with osteoclast like giant cells. The tumor cells stained intensely for vimentin (a mesenchymal marker), but no immunoreactivity for the Cytokeratin Pan (epithelial cells marker), ...
UCOCGC; poorly differentiated carcinoma with osteoclastic giant cells Images Poorly differentiated carcinoma with osteoclast-like giant cells (...)
INTRODUCTION: Pulmonary Sarcomatoid Carcinoma (PSC) is a rare group of tumors accounting for about 0.4% of non-small cell lung carcinoma (NSCLC). Five subtypes were described: pleomorphic carcinoma, spindle cell carcinoma, carcinosarcoma, giant cell carcinoma and pulmonary blastoma. The diagnosis is pathological but requires a good quality sampling of the tumor.. METHODS: On a series of 1582 patients operated on for lung cancer from 1992 to 2016, 43 patients were retrospectively identified as having been treated surgically for pulmonary sarcomatoid carcinoma.. RESULTS: The population consisted of 33 males and 10 females with mean age of 55 years. Imaging findings showed a peripheral mass in the majority of cases (n=29). Careful investigation failed to discover a primitive lesion elsewhere. Six patients received induction therapy for wall involvement. Lobectomy or bilobectomy was performed in 30 patients and pneumonectomy in 11 patients. A wedge resection was performed in one patient and an ...
The mean age of patients was 56.8 years (range, 46-73 years). The CT appearance of the tumor was similar for all our patients: Large mass, peripheral, heterogeneous density, with massive necrotic tissue component that strongly heightened after contrast injection; tumor had a locoregional extension with parietal and bone invasion (n = 5) and a distance extension (n = 4) to the adrenal glands. Pathological examination found a pleomorphic carcinoma (n = 3), a giant cell carcinoma (n = 1) and a carcinosarcoma (n = 2). Sarcomatoid carcinoma diagnosis was increased for the remaining patients without precision of histological subtype. ...
It has been reported that at the onset of pupariation there is an increase of lipid droplets in PG cells that can be seen by Oil Red O staining of precisely staged 120 h AEL wandering larvae (Talamillo et al., 2013). At 120 h AEL, phm,CTCFRNAi PGs had a reduced content of lipid droplets in comparison to controls (Fig. 4B, compare middle and left panels), likely due to developmental delay. However, there is also an increase of lipid droplets at the end of larval development in phm,CTCFRNAi PG cells which tend to be slightly higher than in control animals (Fig. 4B, compare right and left panels and supplementary material Fig. S4). Since the subcellular lipid accumulation phenotype of phm,CTCFRNAi PG cells is similar to that of Niemann-Pick type C (npc) mutants (Huang et al., 2005), we analyzed dnpc1a transcriptional levels but we found no changes between control and phm,CTCFRNAi larvae (data not shown). Increased lipid accumulation in the fat body in EcR knockdown larvae has been reported ...
We also analyzed the latency and jitter (the SD of the latency) of responses to ON stimulation. Across the entire GAD65+ PG cell population latencies ranged from 1.8 to 8.2 ms (mean: 3.61 ± 0.22 ms; Fig. 3D) and jitter ranged from 30 to 2,616 μs (mean: 470 ± 70 μs; Fig. 3E). However, cells with spontaneous and ON-evoked single EPSCs had significantly lower latency (2.63 ± 0.06 ms, range: 1.79-4.08 ms) and jitter (173 ± 9 μs, range: 31-298 μs) than cells with spontaneous and ON-evoked EPSC bursts (latency: 4.62 ± 0.3 ms, P , 0.000001, range: 2.16-8.20 ms; jitter 774 ± 119 μs, P , 0.000001; range: 309-2,616 μs).. ET cells provide monosynaptic burst input to ∼70% of PG cells (Hayar et al. 2004b). Thus the burst-sEPSC PG cell responses to ON input may derive from the disynaptic, ON→ET→PG circuit. However, mitral/tufted (M/T) cells could also contribute to this burst response: Back propagation of action potentials initiated near the M/T cell soma into the apical dendrites might ...

A rare case of aneurysmal bone cyst (ABC) located in the mandibular condyle in a 10-year-old boy is presented. The patient came to our attention for a sudden swelling in the right temporomandibular region, the mouth opening was not reduced. A rapid growing mass, depicting soft tissue invasion, in the right condyle of the mandible was found. Clinically and radiographically it resembled to a malignant lesion. The surgical excision of the mandibular condyle allowed a complete removal of the lesion. The histological examination revealed a pseudocystic expanding osteolytic lesion containing blood-filled space separated by connective tissue and many osteoclastic giant cells, which was a conventional vascular ABC. The ABC is an infrequent bone lesion which can only be found very rarely at the craniofacial skeleton. There have been described about 160 cases of ABC originated in the molar region or in upper maxilla and even more rare is the location of this cyst in the mandibular condyle. Only 6 cases were

NGC 6940 is an open cluster in the constellation Vulpecula. It was discovered by William Herschel in 1784. The cluster is nearly a billion years old and it is located 2,500 light years away. It is considered the finest open cluster in the constellation. It is located a bit more than two degrees south-southeast of 41 Cygni and three and a half degrees southwest from 52 Cygni. The cluster is bright enough to be seen even with small binoculars, which can partially resolve it. NGC 6940 is included in the Herschel 400 Catalogue. NGC 6940 has hundreds of members. The cluster is quite scattered and in between its members are also visible field stars. For example, two bright stars, a 8.6 mag B8III giant star at the NE edge and a 9.1 mag A0III giant at the SW corner of the cluster are too young to be true members of NGC 6940 and are probably background stars. The brightest star (lucida) of NGC 6940 is the red giant VG Vulpeculae, a semiregular variable star whose magnitude ranges from 9.0 to 9.5 every 80 ...
Parent of origin imprints on the genome have been implicated in the regulation of neural cell type differentiation. The ability of human parthenogenetic (PG) embryonic stem cells (hpESCs) to undergo neural lineage and cell type-specific differentiation is undefined. We determined the potential of hpESCs to differentiate into various neural subtypes. Concurrently, we examined DNA methylation and expression status of imprinted genes. Under culture conditions promoting neural differentiation, hpESC-derived neural stem cells (hpNSCs) gave rise to glia and neuron-like cells that expressed subtype-specific markers and generated action potentials. Analysis of imprinting in hpESCs and in hpNSCs revealed that maternal-specific gene expression patterns and imprinting marks were generally maintained in PG cells upon differentiation. Our results demonstrate that despite the lack of a paternal genome, hpESCs generate proliferating NSCs that are capable of differentiation into physiologically functional ...

A giant cell tumor is one that is made up of a large number of benign (noncancerous) cells that form an aggressive tumor, usually near the end of the bone near a joint. The location of a giant cell tumor is often in the knee, but can also involve the bones of the arms and the legs, or the flat bones such as the sternum (breastbone) or pelvis.. Giant cell tumors most often occur in young adults when skeletal bone growth is complete. Most occur in the long bones of the legs and arms.. ...

Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal cells and the presence of many multi- nucleated giant cells with homogenous distribution. There is no widely held consensus regarding the ideal treatment method selection. There are advocates of varying surgical techniques ranging from intra-lesional curettage to wide resection. As most giant cell tumors are benign and are located near a joint in young adults, several authors favor an intralesional approach that preserves anatomy of bone in lieu of resection. Although GCT is classified as a benign lesion, few patients develop progressive lung metastases with poor outcomes. Treatment is mainly surgical. Options of

N2 - Objective: Giant cell tumor of bone (GCTB) is a frequently recurring locally aggressive osteolytic lesion, where pathological osteoclastogenesis and bone destruction are driven by neoplastic stromal cells. Here, we studied if cell cycle fractions within the mononuclear cell compartment of GCTB can predict its progression-free survival (PFS). Methods: 154 cases (100 primaries and 54 recurrent) from 139 patients of 40 progression events, was studied using tissue microarrays. Ploidy and in situ cell cycle progression related proteins including Ki67 and those linked with replication licensing (mcm2), G1-phase (cyclin D1, ...

From UniProt:. Porokeratosis 8, disseminated superficial actinic type (POROK8): A form of porokeratosis, a disorder of faulty keratinization characterized by one or more atrophic patches surrounded by a distinctive hyperkeratotic ridgelike border called the cornoid lamella. The keratotic lesions can progress to overt cutaneous neoplasms, typically squamous cell carcinomas. Multiple clinical variants of porokeratosis are recognized, including porokeratosis of Mibelli, linear porokeratosis, disseminated superficial actinic porokeratosis, palmoplantar porokeratosis, and punctate porokeratosis. Disseminated superficial actinic porokeratosis (DSAP) is the most common subtype. It is characterized by multiple small, annular, anhidrotic, keratotic lesions that are located predominantly on sun-exposed areas of the skin, such as the face, neck, and distal limbs. The lesions typically begin to develop in adolescence and reach near-complete penetrance by the third or fourth decade of life. ...

Patients were genotyped before ...
Understanding Giant cell tumor (GCT) of bone has been described as the most challenging benign bone tumors. The majority of these tumors, classically, are involved in the epiphysis of long bones. Although this disorder is benign, GCTs show a tendency of bone destruction, local recurrence and, occasionally, pulmonary metastasis. But axillary lymohnode metastasis is very very rare. Herein, we present an extremely rare case of axillary mets even after below elbow amputation in a case of recurrent giant cell tumor in a 45 yers male residing at Kolkat,.West Bengal. We treat him by radical axillary lumph node dissection.Lymph node histopatho;ogical report shows Tartrate-resistant acid phosphatase (TRAP) activity.. ...
