Expression data of HGF/cMET pathway in prostate cancer DU145 cell line

ABSTRACT: DU145 prostate cancer cells were treated with 25 ng/ml hepatocyte growth factor (HGF) or vehicle for 2, 8, or 24 hours. HGF stimulates the cMET protein, a tyrosine kinase transmembrane protein. The aim of this study is to determine the role of the HGF/cMET pathway in immature cells of established prostate cancer. HGF stimulation of DU145 prostate cancer cell line led to cell migration in culture, formation of sprouts in Matrigel and inhibition of growth. These biological effects went together with induction of a stem-like phenotype as defined by up-regulation of CD49b, CD49f, CD44 and SOX9, and down-regulation of CD24 on gene-expression arrays and quantitative PCR. The shift towards a stem-like phenotype was reflected by protein modifications on FACS, Western blot, and enhanced rapid adhesion to collagen I. Small molecules SU11274 and PHA665752 were able to inhibit both morphologic and molecular HGF effects.

For each time point two arrays analyses were performed. One for cells stimulated with a vehicle and one for the HGF stimulated cells. Six arrays were performed in total in this study.

Effect of acute HGF-induced cMET activation in MCF10A cells in vitro

Project description:cMET is a well known oncogene whose activation is widely implicated in tumorigenesis and metastasis. To investigate the effects of acute activation of cMET signaling in the mammary epithelial cells, we stimulated MCF10A cells with increasing doses of HGF and analyzed the transcriptional alteration between PBS and HGF treated cells.

Targeting the cMET pathway augments radiation response without adverse effect on hearing in NF2 schwannoma models

Project description:Neurofibromatosis type II (NF2) is a disease that needs new solutions. Vestibular schwannoma (VS) growth cause progressive hearing loss, and the standard treatment including surgery and radiotherapy, can further damage the nerve. There is an urgent need to identify an adjunct therapy that, by enhancing the efficacy of radiation, can help lower the radiation dose and preserve hearing. The mechanisms underlying deafness in NF2 are still unclear. One of the major limitations in studying tumor-induced hearing loss is the lack of mouse models that allows hearing test. Here we developed a cerebellopontine angle (CPA) schwannomas model that faithfully recapitulates the tumor-induced hearing loss. Using this model we discovered that cMET blockade by crizotinib (CRZ) enhanced schwannoma radiosensitivity by enhancing DNA damage, and CRZ treatment combined with low-dose radiation was as effective as high-dose radiation. CRZ treatment had no adverse effect on hearing; however, it did not affect tumor-induced hearing loss, presumably because cMET blockade did not change tumor HGF levels. cMET gene knockdown study independently confirmed the role of cMET pathway in mediating the effect of CRZ. Furthermore, we evaluated the translational potential of cMET blockade in human schwannomas. We found that human NF2-associated and sporadic VSs showed significantly elevated HGF expression and cMET activation compared to normal nerves, which correlated with tumor growth and cyst formation. Using organoid brain slice culture, cMET blockade inhibited the growth of patient-derived schwannomas. Our findings provide the rationale and necessary data for the clinical translation of combined cMET blockade with radiation therapy in NF2 patients. We found that human NF2-associated and sporadic VSs showed significantly elevated HGF expression and cMET activation compared to normal nerves, which correlated with tumor growth and cyst formation.

Expression data from MDCK cells exposed to HGF +/- MAPK inhibitors

Project description:Gene expression in Madin Darby canine kidney cells grown for 7 days to confluence on Transwell filters and exposed to HGF +/- inhibitors of the MAPK pathway (MAPK is one of the pathways activated when HGF binds to the CMET receptor tyrosine kinase). We used microarrays to detail the program of gene expression in MDCK cells and identified genes specifically regulated by HGF via the MAPK pathway. Keywords: signaling pathway analysis

Next Generation Sequencing Facilitates Quantitative Analysis of HGF treated (HGF+) and matched control (HGF-) HepG2 cells

Project description:We report the high-throughput profiling of HGF treated liver cancer cell (HepG2) for differentiated genes analysis. We generated HGF stimulated and paired control HepG2 cells for 4 days. We find that tumor suppressor genes that are overexpressed and some tumor associated genes were downregulated, therefore reflect cell state and HGF induced anti-tumor potential. This study provides a potential framework for the research of HGF induced critical genes in the application of liver cancer therapy.

Expression array analysis of the hepatocyte growth factor (HGF) invasive program

Project description:HGF stimulates mitogenesis, motogenesis and morphogenesis in most epithelial target cells. Selective inhibition of HGF signaling blocks spontaneous metastasis, but not primary tumor growth, in the prostate adenocarcinoma derived PC3M cell xenograft model. To identify the HGF activated genes and pathways that contribute to cell motility and invasion, i.e. the HGF invasive program, expression profiling was performed on PC3M cells that were untreated or were treated with human HGF (hHGF), which drives all 3 primary activities, or with human HGF/NK2 (hNK2) or murine HGF (mHGF), which drive motility and invasion but not proliferation in human cells. Differences in gene expression profiles among these four groups were used to distiniguish between events associated with invasion (resulting from hNK2 or mHGF treatment) from those associated with the combination of invasion and proliferation (resulting from hHGF treatment).
