HSP90B2P and malignant colon neoplasm: Similar to AUY922, quercetin potentiates the effects of many first-line chemotherapeutics including doxorubicin, cisplatin, gemcitabine, and 5-FU.51, –53 Interestingly, the herein presented cell viability data from HSP inhibition assays, using a combination of HSP90 (17-AAG) and HSP70 (VER155008) inhibitors, indeed demonstrated significantly reduced viability in our colon cancer cells previously exposed to hyperthermic chemotherapy, suggesting a beneficial effect of HSP inhibition after HIPEC therapy.
