Because multidrug resistance (MDR) is a serious impediment to the use of chemotherapy in treating cancer patients, great efforts have been made to search for effective MDR-reversing agents. We have developed a brand new synthetic ardeemin derivative, 5-N-formylardeemin, and investigated the activity of which in reversing MDR in MDR cancer cell lines derived from human breast cancer (MCF-7-R) or lung...
Leptin and its receptors are overexpressed in breast cancer tissues and correlate with poor prognosis. Survivin, a member of the inhibitor of apoptosis protein (IAP) gene family, is generally upregulated in tumor tissues and prevents tumor cells from apoptosis. Here we showed that leptin upregulated survivin mRNA and protein expression in MCF-7 breast cancer cells. Meanwhile, leptin suppressed docetaxel-induced...
