BAX and cancer: The formation of the mitochondrial apoptosis-induced channel (MAC), which is formed by binding of tBid with Bax and Bak through activated caspase-8, is hindered by the downregulation of proapoptotic and upregulation of antiapoptotic proteins, which leads to the formation of resistant cancers by inhibiting the release of cytochrome C, a key protein for electron transfer in mitochondria [53].
