Sirt3, one of class III histone deacetylase, is mainly localized in mitochondria and plays a significant role in the control of the metabolic activity, senescence and death [1]. Recently, Sirt3 emerged as a novel member of anticancer. However, the role of Sirt3 in colorectal cancer (CRC) has never been explained exactly. In this study, we found that sirt3 is down-regulated after Bufalin treatment. We also found that AC-P53 is up-regulated which induces Bax translocation to mitochondrion and open the mitochondrial permeability transition (mPTP) pores result in the release of cytochrome C lead to the activation of caspase-dependent apoptosis pathway. Collectively, our data suggests that Sirt3 may play an important role in CRC development and progression and may be a promising therapeutic target for CRC.
