Vielanin K enhances doxorubicin-induced apoptosis via activation of IRE1α- TRAF2 - JNK pathway and increases mitochondrial Ca2 + influx in MCF-7 and MCF-7/MDR cells

Therapeutic failure and drug resistance are common and have important implications in the poor prognosis of advanced breast cancer. It is necessary to acquire a natural product to overcome the resistance of cancer and increase the sensitivity of drug-resistant cells to anticancer agents. To demonstrate whether the compound Vielanin K (VK) has the potential to increase the sensitivity of MCF-7 and MCF-7/MDR cells to anticancer agents. Cell...
