Expression profiling of Sk-Hep1 after PAI-1 silencing (RNAi)

Project description:Methods: To investigate how tumor cell-derived YAP is changing the paracrine communication network between tumor cells and non-tumorous cells in hepatocarcinogenesis, the expression and secretion of cytokines, growth factors and chemokines were analyzed in transgenic mice with liver-specific and inducible expression of constitutively active YAP (YAPS127A). Transcriptomic and proteomic analyses were performed using primary isolated hepatocytes and blood plasma. In vitro, RNAinterference (RNAi), expression profiling, functional analyses and chromatin immunoprecipitation (ChIP) analyses of YAP and the transcription factor TEA domain transcription factor 4 (TEAD4) were performed using immortalized cell lines. Findings were confirmed in cohorts of HCC patients at the transcript and protein levels. Results: YAP overexpression induced the expression and secretion of many paracrine-acting factors with potential impact on other tumorous or non-tumorous cells (e.g. plasminogen activator inhibitor-1 (PAI-1), C-X-C motif chemokine ligand 13 (CXCL13), CXCL16). Expression analyses of human HCC patients showed an overexpression of PAI-1 in human HCC tissues and a correlation with poor overall survival as well as early cancer recurrence. PAI-1 statistically correlated with genes typically induced by YAP, such as connective tissue growth factor (CTGF) and cysteine rich angiogenic inducer 61 (CYR61) or YAP-dependent gene signatures (CIN4/25). In vitro, YAP inhibition diminished the expression and secretion of PAI-1 in murine and human liver cancer cell lines. PAI-1 affects the expression of genes involved in proliferation as well as cellular senescence and oncogene-induced senescence was confirmed in YAPS127A transgenic mice. Silencing of TEAD4 as well as treatment with the YAP/TEAD interfering substance Verteporfin reduced PAI-1 expression. ChIP analyses confirmed the binding of YAP and TEAD4 to the gene promoter of PAI-1 (SERPINE1).

Gene expression profile of TARDBP in hepatocellular carcinoma cell line (SK-Hep1)

Project description:TARDBP is TARDBP (TDP-43) is a DNA/RNA binding protein and was mutated in human amyotrophic lateral sclerosis (ALS). However, its function in human cancer has not been fully identified, yet.Thus, We carried out microarray to investigate the down-stream target genes of TARDBP after silencing TARDBP in liver cancer cell SK-Hep1. To identify the role of TARDBP in hepatocellular carcinoma cell line, we performed microarray after knocking down TARDBP in hepatocellular carcinoma cell line (3 siLuc, 3 siTARDBP)

The effect of IL-37 in HCC cell line Sk-hep1

Project description:We performed whole microarray expressiong prolife of Sk-hep1 cells which could over-express IL-37. This project is to explore the effect of interleukin-37 on hepatocellular carcinoma(HCC) development. We transfected human HCC cell line Sk-hep1 with lentiviral vector encoding IL-37 or control. The successfully transfected cells were sorted by FACS and the cells were further cultured for 24 hours. The cells were harvested and send for microarray analysis.

RNA sequencing results of dipyridamole treatment in SLC29A2-expressing SK-hep1 cells

Project description:We observed an increasing trend of nuclear SLC29A2 expression associated with high histological de-differentiation grades, metastasis and poor patient prognosis by immunohistochemical analysis of HCC tumors. Treatments of dipyridamole to SLC29A2 expressing SK-hep1 cells reduced cell viability and cell migration. To examine the anticancer activities of dipyridamole, transcriptome analysis was performed to detect the modulations of oncogenic SLC29A2 and the downstream signaling pathways.

Effect of PAI-1 knockdown on gene expression in SK-OV-3 cells, and effect of platelets on gene expression in SK-OV-3 cells.

Project description:To investigate the role of PAI-1 (SERPIN E1) in ovarian cancer, we performed several in vitro assays using SK-OV-3 cells in which PAI-1 had been knocked down by siRNA, treated with platelets, or both. We then performed a comparative gene expression analysis using RNA-Seq data from untreated cells, PAI-1 siRNA knockdown or negative control, each with and without incubation with healthy donor platelets.

Gene expression profile of YAP1, TEAD1 and KLF5 in hepatocellular carcinoma cell line (SK-Hep1)

Project description:Hippo signaling pathway is pivotally involved in human cancer. Among the Hippo components, YAP1 is highly active while function of MST1,2 and SAV1 was lost in liver cancer. Based on systematic analysis, we identified KLF5 as YAP1 binding partner in silico. To investigate KLF5 in liver cancer, we performed the gene expression microarray after knocked down YAP1, TEAD1 and KLF5 in SK-Hep1 cell line. To identify the role of YAP1, TEAD1 and KLF5 in hepatocellular carcinoma cell line, we performed microarray after knocking down YAP1, TEAD1 and KLF5 in hepatocellular carcinoma cell line (3 siLuc, 3 siYAP1, 3 siTEAD1, 3 siKLF5)
