The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. 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.

Immunohistochemical expression of mdm2 and p21WAF1 in invasive cervical cancer: correlation with p53 protein and high risk HPV infection. (1/11529)

AIM: To investigate the immunocytochemical staining pattern of mdm2 and p21WAF1 proteins in invasive cervical cancer and to determine its relation with the expression of p53 and with the high risk HPV infection. METHODS: Immunocytochemistry for p53, mdm2, and p21WAF1 was performed in 31 paraffin embedded sections of invasive cervical cancer. The results were assessed by image analysis, evaluating for each protein the optical density of the immunostained area, scored as percentage of the total nuclear area. The presence of high risk human papillomavirus (HPV) infection was detected by using the polymerase chain reaction. RESULTS: Immunostaining for both mdm2 and p21WAF1 was correlated with p53 expression; however, the correlation between p53 and mdm2 (R = 0.49; p < 0.01) was more significant than between p53 and p21WAF1 (R = 0.31; p < 0.05); the less stringent correlation between p53 and p21WAF1 might reflect the p53 independent mechanisms of p21WAF1 induction. Similar average levels of p53, mdm2, and p21WAF1 immunostaining were found in the presence or absence of high risk HPV-DNA, without significant differences between the two groups. CONCLUSIONS: These data suggest that mdm2 and p21WAF1 proteins are expressed in invasive cervical cancer and that their immunocytochemical staining pattern is not abrogated by the presence of high risk HPV genomic sequences.  (+info)

The alphaE-catenin gene (CTNNA1) acts as an invasion-suppressor gene in human colon cancer cells. (2/11529)

The acquisition of invasiveness is a crucial step in the malignant progression of cancer. In cancers of the colon and of other organs the E-cadherin/catenin complex, which is implicated in homotypic cell-cell adhesion as well as in signal transduction, serves as a powerful inhibitor of invasion. We show here that one allele of the alphaE-catenin (CTNNA1) gene is mutated in the human colon cancer cell family HCT-8, which is identical to HCT-15, DLD-1 and HRT-18. Genetic instability, due to mutations in the HMSH6 (also called GTBP) mismatch repair gene, results in the spontaneous occurrence of invasive variants, all carrying either a mutation or exon skipping in the second alphaE-catenin allele. The alphaE-catenin gene is therefore, an invasion-suppressor gene in accordance with the two-hit model of Knudsen for tumour-suppressor genes.  (+info)

Role of thrombin receptor in breast cancer invasiveness. (3/11529)

Invasion, the ability of an epithelial cancer cell to detach from and move through a basement membrane, is a central process in tumour metastasis. Two components of invasion are proteolysis of extracellular matrix and cellular movement through it. A potential promoter of these two processes is thrombin, the serine proteinase derived from the ubiquitous plasma protein prothrombin. Thrombin promotes the invasion of MDA-MB231 breast tumour cells (a highly aggressive cell line) in an in vitro assay. Invasion by MDA-MB436 and MCF-7 cells, less aggressive cell lines, is not promoted by thrombin. Thrombin, added to the cells, is a stimulator of cellular movement; fibroblast-conditioned medium is the chemotaxin. Thrombin-promoted invasion is inhibited by hirudin. Stimulation of invasion is a receptor-mediated process that is mimicked by a thrombin receptor-activating peptide. Thrombin has no effect on chemotaxis in vitro. Thrombin receptor is detectable on the surface of MDA-MB231 cells, but not on the other two cell lines. Introduction of oestrogen receptors into MDA-MB231 cells by transfection with pHEO had no effect on thrombin receptor expression, in the presence or absence of oestradiol. This paper demonstrates that thrombin increases invasion by the aggressive breast cancer cell line MDA-MB231 by a thrombin receptor-dependent mechanism.  (+info)

Expression of pyrimidine nucleoside phosphorylase mRNA plays an important role in the prognosis of patients with oesophageal cancer. (4/11529)

To clarify the significance of the expression of pyrimidine nucleoside phosphorylase (PyNPase) mRNA as a predictive factor for the prognosis of patients with oesophageal carcinoma, the PyNPase mRNA in the tumours and normal tissues from 55 resected cases of oesophageal carcinoma was examined by a reverse transcription polymerase chain reaction (RT-PCR). As a result, a positive correlation was observed between the tumour/normal (T/N) ratio of the expression of PyNPase mRNA by RT-PCR and that of the enzyme activity of PyNPase based on the findings of an enzyme linked immunosolvent assay (r = 0.594, P = 0.009). The T/N ratio of the expression of PyNPase mRNA was significantly higher in the cases with lymph vessel invasion (P = 0.013), lymph node metastasis (P = 0.0016), and an advanced stage of the disease (P = 0.021) than those without these factors. The patients with a higher T/N ratio of PyNPase mRNA showed significantly worse prognosis than those with a lower T/N ratio (P = 0.023 with log-rank tests). A multivariate analysis for the cumulative survival rates revealed that a high T/N ratio of the expression of PyNPase mRNA was independently related to a poor prognosis. These findings suggested that the determination of PyNPase mRNA by RT-PCR thus appears to be a new useful parameter for identifying both a poor prognosis and a highly malignant potential of oesophageal carcinoma.  (+info)

Low tumour cell proliferation at the invasive margin is associated with a poor prognosis in Dukes' stage B colorectal cancers. (5/11529)

The conflicting results about the prognostic impact of tumour cell proliferation in colorectal cancer might be explained by the heterogeneity observed within these tumours. We have investigated whether a systematic spatial heterogeneity exists between different compartments, and whether the presence of such a systematic heterogeneity has any impact on survival. Fifty-six Dukes' stage B colorectal cancers were carefully morphometrically quantified with respect to the immunohistochemical expression of the proliferative marker Ki-67 at both the luminal border and the invasive margin. The proliferative activity was significantly higher at the luminal border compared with the invasive margin (P<0.001), although the two compartments were also significantly correlated with each other. Tumours with low proliferation at the invasive margin had a significantly poorer prognosis both in univariate (P = 0.014) and in multivariate survival analyses (P = 0.042). We conclude that Dukes' B colorectal cancers exhibit a systematic spatial heterogeneity with respect to proliferation, and tumours with low proliferation at the invasive margin had a poor prognosis. The present data independently confirm recent results from the authors, and provide new insights into the understanding of tumour cell proliferation in colorectal cancer.  (+info)

A possible involvement of aberrant expression of the FHIT gene in the carcinogenesis of squamous cell carcinoma of the uterine cervix. (6/11529)

To investigate involvement of an aberrant expression of the FHIT (fragile histidine triad) gene in the process of carcinogenesis and progression in cervical carcinoma, we examined its expression by the reverse transcriptase polymerase chain reaction (RT-PCR) and cDNA sequence method in 32 cervical invasive carcinomas (25 squamous cell carcinomas and seven adeno- or adenosquamous carcinomas) and 18 of its precursor lesions [four low-grade and 14 high-grade cervical intraepithelial neoplasias (CINs)]. We also examined a link between the occurrence of the aberrant expression and human papillomavirus (HPV). We detected the aberrant FHIT transcripts in 11 of 25 (44%) cervical invasive squamous cell carcinomas and in 5 of 14 (36%) high-grade CINs (CIN 2 or 3), whereas they were not found in seven non-squamous type and four low-grade CINs (CIN 1). The alteration patterns of the FHIT gene expression in high-grade CINs were virtually similar to those found in invasive carcinomas, such that the exons 5-7 were consistently deleted associated or unassociated with loss of the exon 4 and/or 8. The incidence of the aberrant expression was not related to the presence of HPV and its type. These data indicate that the aberrant expression of the FHIT gene is observed in precursor lesions of cervical carcinoma as well as invasive carcinomas, with its incidence not increasing with advance of clinical stage. Given the squamous cell type dominant expression, the aberrant expression may play a critical role in the generation of squamous cell carcinoma of the uterine cervix, but not the consequence of the progression of the cancer.  (+info)

Enhanced tumor growth and invasiveness in vivo by a carboxyl-terminal fragment of alpha1-proteinase inhibitor generated by matrix metalloproteinases: a possible modulatory role in natural killer cytotoxicity. (7/11529)

Matrix metalloproteinases (MMPs) are believed to contribute to the complex process of cancer progression. They also exhibit an alpha1-proteinase inhibitor (alphaPI)-degrading activity generating a carboxyl-terminal fragment of approximately 5 kd (alphaPI-C). This study reports that overexpression of alphaPI-C in S2-020, a cloned subline derived from the human pancreas adenocarcinoma cell line SUIT-2, potentiates the growth capability of the cells in nude mice. After stable transfection of a vector containing a chimeric cDNA encoding a signal peptide sequence of tissue inhibitor of metalloproteinase-1 followed by cDNA for alphaPI-C into S2-020 cells, three clones that stably secrete alphaPI-C were obtained. The ectopic expression of alphaPI-C did not alter in vitro cellular growth. However, subcutaneous injection of the alphaPI-C-secreting clones resulted in tumors that were 1.5 to 3-fold larger than those of control clones with an increased tendency to invasiveness and lymph node metastasis. These effects could be a result of modulation of natural killer (NK) cell-mediated control of tumor growth in nude mice, as the growth advantage of alphaPI-C-secreting clones was not observed in NK-depleted mice, and alphaPI-C-secreting clones showed decreased NK sensitivity in vitro. In addition, production of alphaPI and generation of the cleaved form of alphaPI by MMP were observed in various human tumor cell lines and in a highly metastatic subline of SUIT-2 in vitro. These results provide experimental evidence that the alphaPI-degrading activity of MMPs may play a role in tumor progression not only via the inactivation of alphaPI but also via the generation of alphaPI-C.  (+info)

Collagenase-3 (MMP-13) is expressed by tumor cells in invasive vulvar squamous cell carcinomas. (8/11529)

Collagenase-3 (MMP-13) is a human matrix metalloproteinase specifically expressed by invading tumor cells in squamous cell carcinomas (SCCs) of the head and neck. Here, we have further elucidated the role of MMP-13 in tumor invasion by examining its expression in invasive malignant tumors of the female genital tract. Using in situ hybridization, expression of MMP-13 mRNA was detected in 9 of 12 vulvar SCCs, primarily in tumor cells, but not in intact vulvar epithelium, in cervical SCCs (n = 12), or in endometrial (n = 11) or ovarian adenocarcinomas (n = 8). MMP-13 expression was especially abundant in vulvar carcinomas showing metastasis to lymph nodes and was associated with expression of membrane type 1 MMP by tumor cells and gelatinase-A (MMP-2) by stromal cells, as detected by immunohistochemistry. MMP-13 mRNAs were detected in 9 of 11 cell lines established from vulvar carcinomas and in 4 of 6 cell lines from cervical carcinomas, whereas endometrial (n = 10) and ovarian (n = 9) carcinoma cell lines were negative for MMP-13 mRNA. No correlation was detected between MMP-13 expression and p53 gene mutations in vulvar SCC cell lines. However, MMP-13 expression was detected in 5 of 6 vulvar and cervical SCC cell lines harboring HPV 16 or 68 DNA. These results show that MMP-13 is specifically expressed by malignantly transformed squamous epithelial cells, including vulvar SCC cells, and appears to serve as a marker for their invasive capacity.  (+info)

Keywords: Arsenic trioxide, Thalidomide, Vascular Endothelial Development Factor (VEGF), severe myeloid leukemia Launch Severe myeloid leukemia (AML) may be the heterogeneous malignant which is normally seen as a the uncontrolled proliferation of hematopoietic stem cells and myeloid (D?hner et al., 2015; Mohammadi et al., 2016). Although with typical AML regiment many sufferers obtain remission originally, but ultimately relapse occur because of chemotherapy evaded leukemic stem cells (Mohammadi et al., 2017a; Mohammadi et al., 2017b). Angiogenesis is normally a regulated procedure, which creates brand-new arteries from a pre-existing vascular network (Kerbel, 2008), and has an important function in the development of hematolymphoid malignancies. Vascular Endothelial Development Factor (VEGF) is normally a 46 KD heparin-binding homodimer protein including six different isoforms specifically VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E and VEGF-F (Tischer et al., 1991; Lei et al., 1998; Mirzaei et al., ...

Heparan sulfate 3-O-sulfotransferase 2 (HS3ST2), an enzyme mediating 3-O-sulfation of heparan sulfate (HS), is silenced by hypermethylation in breast cancer. As HS has an important co-receptor function for numerous signal transduction pathways, the phenotypical changes due to HS3ST2 reexpression were investigated in vitro using high and low invasive breast cancer cell lines. Compared to controls, highly invasive HS3ST2-expressing MDA-MB-231 cells showed enhanced Matrigel invasiveness, transendothelial migration and motility. Affymetrix screening and confirmatory real-time PCR and Western blotting analysis revealed increased expression of several matrix metalloproteinases, cadherin-11, E-cadherin and CEACAM-1, while protease inhibitor and annexin A10 expression were decreased. Low invasive HS3ST2 -expressing MCF-7 cells became even less invasive, with no change in gelatinolytic MMP activity. HS3ST2 expression increased HS-dependent basal and FGF2-specific signaling through the constitutively ...
By using microarray and an invasion/metastasis lung cell line model, we identified the DnaJ-like heat shock protein 40, HLJ1, and found that the expression of HLJ1 correlates negatively with cancer cell invasion ability . Overexpression of HLJ1 can suppress cancer cell invasion in vitro. We further characterize the putative promoter region and investigate the transcriptional regulations of human HLJ1. A serial deletion of the 1.2 kb at the 5′-flanking region of the human HLJ1 gene was subcloned into a vector containing reporter gene and transfected into human lung adenocarcinoma cell line CL1-0, followed by luciferase activity assay. The results indicated that the region from -232 to +176 could drive the basal transcriptional activity of the HLJ1 gene. Sequence analysis of the HLJ1 gene promoter region showed absence of a TATA box, but identified an inverted CCAAT box and four YY1 transcriptional factor-binding sites, which may be important in the regulation of HLJ1 expression. Co- ...
Cancer invasion involves the growth of the tumor and the invasion of cancer cells. During this process, the tumor typically elongates protrusion-like structures, which triggers the invasion of cells into the blood vessel, and thereby, initiate metastasis. Recent evidences using individual cells have identified the key role of membrane protrusion fluctuations in the physicochemical mechanism of directed cell motion]. The exact roles of protrusion fluctuations during tumor growth and invasion have yet not been reported. Different in vitro and in vivo models have been developed to monitor cancer invasion and its mechanistic determinants. These models display certain limitations, which threaten the relevancy of the obtained data. In contrast, organs-on-chip devices can replicate all the key cellular, structural, and rheological properties of solid tumors, contributing to assess the mechanism at work of the disease. In this work, an organ-on-chip approach is used to analyze the important role of ...

The results of the current study showed the molecular and functional activation of β-catenin by hypoxia in HCC and showed its contribution to hypoxia-induced metastatic phenotypes. The induction of EMT was one of the proinvasive mechanisms augmented by β-catenin during hypoxia. The coexpression of β-catenin and HIF-1α (a marker of hypoxia) in HCC was found to be correlated with metastases and poor prognosis in two independent cohorts of patients. These results confirm the importance of β-catenin in HCC under hypoxic conditions.. Hypoxia plays a critical role in tumor progression (1). Consistent with our previous report (17), it not only facilitated in vitro cell invasion in HCC but also resulted in peritoneal seeding and pulmonary metastasis in an in vivo HAL model. However, the growth of HCC cells and xenografts were suppressed by hypoxia. Further analysis revealed that this could be attributed to the arrest of cell proliferation rather than the induction of apoptosis (Supplementary Fig. ...

BACKGROUND: Ubiquitination is a highly dynamic and reversible process with a central role in cell homeostasis. Deregulation of several deubiquitinating enzymes has been linked to tumor development but their specific role in prostate cancer progression remains unexplored. METHODS: RNAi screening was used to investigate the role of the ovarian tumor proteases (OTU) family of deubiquitinating enzymes on the proliferation and invasion capacity of prostate cancer cells. RhoA activity was measured in relation with OTUB1 effects on prostate cancer cell invasion. Tumor xenograft mouse model with stable OTUB1 knockdown was used to investigate OTUB1 influence in tumor growth. RESULTS: Our RNAi screening identified OTUB1 as an important regulator of prostate cancer cell invasion through the modulation of RhoA activation. The effect of OTUB1 on RhoA activation is important for androgen-induced repression of p53 expression in prostate cancer cells. In localized prostate cancer tumors OTUB1 was found overexpressed as

To understand the invasive characteristic of GBM, it is necessary to study cell-ECM interaction in the physiologically relevant biomimetic model that recapitulates the GBM-specific ECM microenvironment. Here, we propose biomimetic GBM-specific ECM microenvironment for studying mode and dynamics of glioblastoma cell invasion. Using tissue decellularization process, we constructed a patient tissue-derived ECM (pdECM)-based three-dimensional in vitro model. In our model, GBM cells exhibited ...
Peroxisome proliferator-activated receptor β (PPARβ) and NaV1.5 voltage-gated sodium channels have independently been shown to regulate human breast cancer cell invasiveness. The n-3 polyunsaturated docosahexaenoic acid (DHA, 22:6n-3), a natural ligand of PPAR, is effective in increasing survival and chemotherapy efficacy in breast cancer patient with metastasis. DHA reduces breast cancer cell invasiveness and it also inhibits PPARβ expression. We have shown previously that NaV1.5 promotes MDA-MB-231 breast cancer cells invasiveness by potentiating the activity of Na(+)/H(+) exchanger type 1 (NHE-1), the major regulator of H(+) efflux in these cells. We report here that DHA inhibited NaV1.5 current and NHE-1 activity in human breast cancer cells, and in turn reduced NaV1.5-dependent cancer cell invasiveness. For the first time, we show that antagonizing PPARβ, or inhibiting its expression, reduced NaV1.5 mRNA and protein expression and NaV1.5 current, as well as NHE-1 activity and cell ...

Epidermal growth factor receptor (EGFR), a receptor tyrosine kinase, is implicated in many cancers; however, it is unclear specifically which EGFR pathways are involved in triggering tumor cell invasiveness. The abundance of the small guanosine triphosphatase Arf6, which regulates processes such as membrane trafficking and endocytosis, correlates with the invasiveness of malignant breast cancer cells. In this context, Morishige et al. used small interfering RNA (siRNA) to individually decrease the expression of the 10 genes that encode guanine nucleotide exchange factors (GEFs) that activate Arf family proteins in the invasive human breast cancer cell line MDA-MB-231. GEP100 was the only ArfGEF whose depletion resulted in the inhibition of MDA-MB-231 invasion activity, as measured by an in-gel invasiveness assay. Coimmunoprecipitation studies showed that EGF treatment of MDA-MB-231 cells triggered the association of GEP100 with EGFR. In transfected Cos-7 cells, the authors showed the ...

Background Stromal fibroblasts can contribute to tumor invasion through the release of matrix metalloproteinases (MMPs). Population studies have suggested that single nucleotide polymorphisms (SNPs) in MMP genes influence levels of expression and may be associated with breast cancer risk and with disease progression. This study directly examined the impact of MMP SNP genotype on the ability of host fibroblasts to promote tumor cell invasion. Methods Primary breast fibroblasts were isolated from patients with (n = 13) or without (n = 19) breast cancer, and their ability to promote breast cancer cell invasion was measured in in vitro invasion assays. Fibroblast invasion-promoting capacity (IPC) was analyzed in relation to donor type (tumor or non-tumor patient), MMP-1, MMP-3, and MMP-9 SNP genotype and MMP activity using independent samples t test and analysis of variance. All statistical tests were two-sided. Results Tumor-derived fibroblasts promoted higher levels of invasion than normal ...
Platelet-cancer cell interactions play a key role in successful haematogenous metastasis. Disseminated malignancy is the leading cause of death among ovarian cancer patients. It is unknown why different ovarian cancers have different metastatic phenotypes. To investigate if platelet-cancer cell interactions play a role, we characterized the response of ovarian cancer cell lines to platelets both functionally and at a molecular level. Cell lines 59 M and SK-OV-3 were used as in vitro model systems of metastatic ovarian cancer. Platelet cloaking of each cell line was quantified by flow cytometry. Matrigel invasion chamber assays were used to assess the invasive capacity of the cell lines. The induction of an EMT was assessed by morphology analysis and by gene expression analysis of a panel of 11 EMT markers using TaqMan RT-PCR. SK-OV-3 cells adhered to and activated more platelets than 59 M cells (p = 0.0333). Platelets significantly promoted the ability of only SK-OV-3 cells to invade (p ≤ 0.0001).

4360 Secreted acidic protein rich in cysteine (SPARC) has been suggested as a potential glioma invasion promoting gene. SPARC is highly expressed in human gliomas, promotes glioma invasion, and delays tumor growth in vitro and in vivo. cDNA array reports were performed to determine whether SPARC, which interacts at the cell surface, has an impact on intracellular signaling and downstream gene expression changes that might account for some of its effects on invasion and growth. Additional in vitro studies demonstrated that SPARC delays growth, increases attachment, and modulates migration of tumor cells in extracellular matrix-specific and concentration-dependent manners. It has been reported that SPARC functionally contributes to brain tumor invasion and delays tumor growth in vivo, and that the effects of SPARC are related to the level of SPARC secreted into the extracellular matrix. Thus far, the signaling aspects of glioma migration and invasion are not fully understood. As such, we made an ...
Furin, a subtilisin/kesin-like proprotein convertase (PC), activates membrane-bound MT1-MMP, which facilitates pro-gelatinase A (MMP2). These activated MT1-MMP and MMP2 are involved in cancer cell invasion and metastasis. In this study, we investigate the contribution of MMP2 activated by furin to cellular invasiveness of cumulatively irradiated cells.. Using previously established AMC-HN3 and AMC-HN8 cell line from laryngeal carcinoma patient, we have generated isogenic model of cumulatively irradiated AMC-HN3R and AMC-HN8R cell line, respectively. AMC-HN3R cells were increased furin expression with upregulation of MT1-MMP/MMP2 and their invasiveness by two fold (p , 0.05) compared to AMC-HN3, while AMC-HN8R cells had no differences compared to AMC-HN8. In case of AMC-HN3R, inhibition of furin activity with the synthetic inhibitor decanoyl-Arg-Val-Lys-Arg-chloromethyl-keton, CMK, showed a significant decrease of MT1-MMP/MMP2 and in vitro cellular invasiveness. Tumors obtained after subcutaneous ...

We previously showed that EGF and other growth factors induce human carcinoma cell invasion and metastasis mediated by integrin αvβ5 that is prevented by Src blockade [1]. MUC1, a transmembrane glycoprotein, is expressed in most epithelial tumors as a heterodimer consisting of an extracellular and a transmembrane subunit. The MUC1 cytoplasmic domain of the transmembrane subunit (MUC1.CD) translocates to the nucleus where it promotes the transcription of ...

Chemotherapy is widely used to treat metastatic disease. However, while many patients initially respond, a high percentage of them ultimately relapse. Cells plated in a monolayer respond much better to cytotoxic therapy than the same cells grown in 3D spheroids, or in xenograft tumors in mice, suggesting that the ECM and stromal cells that make up the tumor microenvironment drive drug resistance. While there has been work highlighting mechanisms of resistance derived from the release of cytokines from stromal cells, the role of the ECM in this process remains understudied in 3D in vitro systems or in vivo using mouse models. In addition, how chemotherapy treatment alters the ECM remains unknown. Finally, most studies focus on the effect chemotherapeutics on cell death, while the potentially dangerous effects of these drugs on tumor cell invasion and metastatic capability remain understudied. Our preliminary data show that chemotherapeutics can have different effects on growth and motility in ...
Celldance 2015: Spying on Cancer Cell Invasion, by Edison Leung with Allison Harney, John Condeelis lab, Albert Einstein College of Medicine.
Perineural invasion (PNI) is thought to be one of the factors responsible for the high rate of tumor recurrence after surgery and the pain generation associated with pancreatic cancer. Signaling via the nerve growth factor (NGF) pathway between pancreatic cancer cells and the surrounding nerves has been implicated in PNI, and increased levels of these proteins have been correlated to poor prognosis. In this study, we examine the molecular mechanism of the NGF signaling pathway in PNI in pancreatic cancer. We show that knocking down NGF or its receptors, TRKA and p75NTR, or treatment with GW441756, a TRKA kinase inhibitor, reduces the proliferation and migration of pancreatic cancer cells in vitro ...

Human bodies are highly fluctuating complex systems. They detect and integrate the clues from changing environments and their own internal states, making numerous responses after delicate computation and regulation. Traditional routes of drug administration includes oral intake or intravenous injection may be too simplified to promptly fit the real-time condition of the body states. In addition, the frequent and repetitive intake of drugs may be annoying, and sometimes the invasive processes are suffering, bringing inconvenience to our daily lives. Medical instruments or electrical monitors can instantaneously detect and response to some specific physiological or pathological parameters, but they are usually too heavy and bulky to carry, which restrict the mobility of patients while using it. Therefore we aim to program the intestinal microbes to build our novel smart drug delivery systems-PEPDEX. There are around \(10^{13}\) to \(10^{14}\) microorganisms inhabiting in our gastrointestinal ...
