Ontology highlight
ABSTRACT: Purpose: To determine biological impact between silencing HuR and YAP1, in MIA-PaCa2. Methods: Expression profiling of MIA-PaCa2 cells knocked-down for HuR and YAP1 and control cells transfected with scramble siRNA.
Project description:To investigate the impact of the mRNA stabilty factor HuR on the pancreatic cancer transcriptome in MIA PaCa-2 in vitro cell line and in vivo tumors at multiple time points of tumor growth
Project description:RNA binding protein, Human Antigen R (HuR/ELAVL1), regulates mRNA stability of key species involved in pancreatic ductal adenocarcinoma (PDAC) cell survival under conditions of chemotherapeutic stress, hypoxia, low glucose environment. We used RNA immunoprecipitation-microarray or RNP-IP from cytoplasmic extracts of PDAC cell lines exposed to chemotherpaeutic stress (olaparib and gemcitabine) to evaluate whole transcriptome gene expression profile associated with HuR and find novel trargtes associated with DNA repair functions of HuR.
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)
Project description:Transcriptional profiling of human hTERT-RPE1 cell spheroids comparing Control siRNA transfected hTERT-RPE1 cell spheroids with those transfected with YAP1 siRNA. Two-condition experiment, Control siRNA vs.YAP1 siRNA hTERT-RPE1 cell spheroids. Biological replicates: 1 Control siRNA, 1YAP1 siRNA transfected, independently grown and harvested. Bothreplicates per array.

Project description:Yes-associated protein 1 (YAP1) is an effector of Hippo pathway, which is critical for regulating organ size, cell proliferation and tumor growth in mammals. YAP1 is known to be involved in tumorigenesis in several tissues, yet its role in colorectal cancer(CRC) is not established. To investigate the effect of YAP1 in CRC, we used microarrays to compared human colon cancer cell line HCT116 transfected with a control non-targeting siRNA to cells and transfected with siRNA targeting YAP1.
