Project description:The hypoxia response contributes to radio and chemo-resistance in cancer cells. Our previous work has shown that the nitric oxide donating non-steroidal anti-inflammatory drug (NO-NSAID) NO-sulindac is a potent inhibitor of the hypoxia response in prostate cancer cells and leads to increased susceptibilty to radiation. In this study we used microarrays to investigated the global impact of NO-sulindac on the hypoxia response in prostate cancer cells with a view to determining the mechanism of action. PC3 hormone-insensitive prostate cancer cells were grown under normoxic or hypoxic conditions and treated with NO-sulindac, unnitrated sulindac or vehicle control. Global gene expression in response to treatment was examined using microarrays and the bioconductor software suite. Gene set enrichment analysis (GSEA), Gene ontology (GO) analysis and pathway analysis were used to examine the biological impact of treatments.
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.
