Simvastatin downregulated C35 expression and inhibited the proliferation of colon cancer cells Lovo and HT29 in vitro

Abstract

The aim of this study was to investigate the antitumor effect of simvastatin in human colon cancer and the possible underlying mechanism. We found that simvastatin dose-dependently inhibited the proliferation of human colon cancer cells Lovo and HT29 using a MTT assay. Real-time PCR and Western blotting assays showed that simvastatin significantly suppressed C35 expression at both mRNA and protein levels. Since C35 is known to have a significant oncogenic role in cancer development via promoting cell proliferation and migration, results obtained in the current study imply that downregulation of C35 expression might be involved in the antitumor effect of simvastatin on colon cancer.
