Expression Data from HNF1b-knockdown RMG2-ovarian cancer cells. Homo sapiens

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. Overall design: 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.
