Project description:It has been demonstrated that Ring finger protein 43 (RNF43) is overexpressed in colorectal cancer and mediates cancer cell proliferation. We found that RNF43 was frequently overexpressed in HCC, and knockdown of RNF43 could induce apoptosis and inhibit proliferation, invasion, colony formation and xenograft growth of HCC cells. Suggesting that RNF43 is involved in tumorigenesis and progression of HCC. We used microarrays to profile gene expression patterns before and after RNF43 knockdown, and identified differentially expressed genes during this process. HepG2 cells were transfected with RNF43 siRNA or negative control siRNA in triplicate. Forty-eight hours after transfection, total RNA was extracted,labeled and hybridized to HG-U133 Plus 2.0 arrays.

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:To identify genes and pathways downstream of Canonical WNT signaling in prostate cancer, we performed RNA sequencing to capture the transcriptional changes upon APC knockdown or RNF43 knockdown plus Wnt3a stimulation in VCaP cells. The global changes of gene expression were assessed by comparing APC knockdown with Control knockdown or RNF43 knockdown plus Wnt3a stimulation with RNF43 knockdown. By overlapping the genes differentially expressed under both conditions, we obtained a bona fide WNT/β catenin downstream effectors list in prostate cancer.
