Molecular Signature of response and potential pathways related to resistance to the HSP90 inhibitor, 17-AAG, in breast cancer.

ABSTRACT: We have done transcriptional profiling of 17-AAG treated (24h, 48H) breast cancer cell lines to understand the mechanisms of the drug action and indicate novel set of pharmacodynamic biomarkers of the drug response as well as of resistance

Drug combination of 17-AAG and Belinostat on MDA-MB-231 breast cancer cells

Project description:Breast cancer is the most common cancer that threatens women's health. While the strategy of drug combination can help to reduce adverse effects and to overcome the resistance of clinical treatment of single drug. In this work, we report the synergetic effect between a HSP90 inhibitor 17-AAG and a HDAC inhibitor Belinostat, on the triple-negative breast cancer MDA-MB-231 cells. The RNA-Seq data analysis showed that the most over-represented KEGG pathways in the combination group came from migration or invasion related genes, which were not observed in the differentially expressed genes after the treatment of 17-AAG or Belinostat alone.

Expression data from human colonic cancer cell line SW480 and its acquired 17-AAG resistance cell line SW480-R

Project description:Heat shock protein 90 (HSP90) is a molecular chaperone required for the stability and function of many proteins. The chaperoning of oncoproteins by HSP90 enhances survival, growth and invasive potential of cancer cells. HSP90 inhibitors are promising new anticancer agents, in which the benzoquinone ansamycin 17-allylamino-17-demethoxygeldanamycin (17-AAG) is currently in clinical evaluation. However, the implications of acquired resistance to this class of drug remain largely unexplored. In the present study, we have generated isogenic human colonic cancer cell line SW480 that is resistant to 17-AAG by continued culturing in the compound. We used microarrays to detail the global programme of gene expression underlying the acquired resistance to 17-AAG in SW480 and SW480-R cell lines.
