Abstract

Ginsenoside F2 (F2) was assessed for its antiproliferative activity against breast cancer stem cells (CSCs). F2 induced apoptosis in breast CSCs by activating the intrinsic apoptotic pathway and mitochondrial dysfunction. Concomitantly, F2 induced the formation of acidic vesicular organelles, recruitment of GFP-LC3-II to autophagosomes, and elevation of Atg-7 levels, suggesting that F2 initiates an autophagic progression in breast CSCs. Treatment with an inhibitor of autophagy enhanced F2-induced cell death. Our findings provide new insights into the anti-cancer activity of F2 and may contribute to the rational use and pharmacological study of F2.
