Abstract

This article explores the effects of atorvastatin on cultured breast Cancer cells. Our experiment demonstrated that atorvastatin triggered Autophagy and inhibited proliferation in breast Cancer cells. A CCK8 assay indicated that atorvastatin can inhibit the activity of MDA-MB-231 breast Cancer cells. Western blotting results showed that atorvastatin increased the conversion of LIGHT chain 3 (LC3)-I to LC3-phosphatidylethanolamine conjugate (LC3-II). Confocal microscopy was used to reveal the appearance of a punctate structure in the cytoplasm, and electron microscopy was used to reveal the formation of double-membrane autophagosome. In conclusion, our study showed that atorvastatin may affect MDA-MB-231 breast Cancer cells by inducing Autophagy.
