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

ABSTRACT: 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 MDCK cells were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain expression of genes regulated by the MAPK pathway following HGF induction.

Matrix metalloproteinase 13 (MMP13) and tissue inhibitor of matrix metalloproteinase 1 (TIMP1), regulated by the MAPK pathway, are both necessary for Madin-Darby canine kidney tubulogenesis.

A classic model of tubulogenesis utilizes Madin-Darby canine kidney (MDCK) cells. MDCK cells form monoclonal cysts in three-dimensional collagen and tubulate in response to hepatocyte growth factor, which activates multiple signaling pathways, including the mitogen-activated protein kinase (MAPK) pathway. It was shown previously that MAPK activation is necessary and sufficient to induce the first stage of tubulogenesis, the partial epithelial to mesenchymal transition (p-EMT), whereas matrix met ...[more]

RNA-seq of canine MDCK epithelial cell line compared to cell line overexpressing ERK2 or cell line with conditional activation of the ERK pathway

Project description:Using RNA-seq and canine MDCK epithelial cells, we analyzed mRNA expression profiles of cells overexpressing ERK2 and cells where the ERK pathway was activated for 24 hrs. For this purpose, three cell lines were used: parental MDCK cells, MDCK cells overexpressing FLAG-ERK2 or MDCK cells expressing conditionally active Raf protein (ΔRaf1:ER). Activation of the ERK pathways was achieved by the addition of 4-Hydroxytamoxifen that converts ΔRaf1:ER protein to the active form and it subsequently activates the ERK pathway.

2D and 3D Madin-Darby Canine Kidney Cell Type II cell line response to hepatocyte growth factor

Project description:Analysis of 2D (transwell) and 3D (collagen type I) cultured MDCK cells and HGF (a MAPK activator). Traditional 2D cultures are fast and inexpensive but do no mimic natural niche/cell environment as well as the more laborious and costly 3D-cultures. 3D cultures, arguably, are better models for the study of developmental processes, such as tubulogenesis. Epithelial organs (such as kidney) develop via tubulogenesis, a process, at least in part, regulated by MAPK signaling. Therefore, 2D and 3D cells also treated with HGF plus MAPK inhibitors. Results provide insights into differential response to HGF-induced tubulogenesis depending on cell culture conditions (2D vs. 3D). 29 samples total: 2D and 3D control (untreated) in quadruplicate, respectively; 2D and 3D + HGF in quadruplicate, respectively; 2D + HGF + PD-98059 in quadruplicate; 3D + HGF + PD-98059 in triplicate; 2D + HGF + U0126 in triplicate; and 3D + HGF + U0126 in triplicate.

Gene expression of normal MDCK cells mixed with normal MDCK cells or RasV12-transformed MDCK cells

Project description:To investigate whether and how the presence of RasV12-transformed cells influences the gene expression profile of the neighbouring normal epithelial cells, we performed microarray analysis. Normal Madin-Darby canine kidney (MDCK) cells were co-cultured with MDCK cells expressing GFP or GFP-RasV12. GFP-negative normal MDCK cells were then collected by FACS, and expression of various genes was compared between the two conditions.

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

Project description: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. DU145 cells were stimulated for 2, 8 and 24 hours with 25 ng/ml HGF or vehicle. 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.
