Downregulation of TIGAR sensitizes the antitumor effect of physapubenolide through increasing intracellular ROS levels to trigger apoptosis and autophagosome formation in human breast carcinoma cells.

Abstract

Physapubenolide (PB) is a cytotoxic withanolide isolated from Physalis angulata that was used as a traditional Chinese medicine. In this study, we investigated the role of TIGAR and ROS in PB-induced apoptosis and autophagosome formation in human breast carcinoma MDA-MB-231 and MCF-7 cells. PB induced apoptosis by decreasing mitochondrial membrane potential… (More)
