Project description:Genome-wide association studies (GWAS) and fine-mapping have identified several distinct variants within HNF1B associated with risk of prostate cancer, but its mechanism of action in this context is unknown. To determine the effects of HNF1B in prostate cancer, we over-expressed HNF1B in PC3 cells to identify biological pathways affected by this change, and performed in vitro assays to validate our findings.
Project description:Comparison of cistromes from GLIS3 and HNF1b ChIP-Seq analysis using mouse kidney was performed to examine whether there was a significant overlap in target genes between GLIS3 and HNF1b.
Project description:Ovarian clear cell carcinoma (OCCC) is a morphologically and biologically distinct subtype of ovarian carcinomas. We previously reported a gene expression profile characteristic of OCCC (OCCC signature), which contains hepatocyte nuclear facter-1b ( HNF-1b). To elucidate the biological role of HNF-1b in OCCC, we performed the suppression of the HNF-1b expression in human ovarian cancer cell line RMG2 using short hairpin RNA. We are now evaluating the functional effect using these cells. Affimetrix Human Genome U133A plus 2.0 chips was conducted for HNF1b knockdown and non-silencing cells (five replicates each for RMG2-HNF1b-sh1 and RMG2-HNF1b-sh2, ten replicates for the RMG2-control). All specimens were arrayed in parallel and used for RMA normalization.
Project description:Hepatocyte nuclear factor 1B (HNF1B) encodes a transcription factor expressed in developing human kidney epithelia. Heterozygous HNF1B mutations are the commonest monogenic cause of dysplastic kidney malformations (DKMs). To understand their pathobiology, we generated heterozygous HNF1B mutant kidney organoids from CRISPR-Cas9 gene-edited human ESCs and iPSCs reprogrammed from a family with HNF1B-asscociated DKMs. Mutant organoids contained enlarged malformed tubules and displayed deregulated cell turnover. This submission contains kidney tissue samples.
Project description:This SuperSeries is composed of the following subset Series:; GSE1589: Targets of HNF1b, HNF4a2 and HNF6 in INS-1 cells; GSE1590: Targets of HNF1b mutants in INS-1; GSE1591: INS-1 cell lines (FLP-In T-REx) Experiment Overall Design: Refer to individual Series
Project description:The complete specrtum of genes that are subject to regulation by Hnf1b in mouse kidney cells is not known. We used microarray to determine genes that are significenlty deregulated in repsonse to altered HNF1b activity.
