We show that E1A alone transformed primary baby mouse kidney epithelial cells (BMK) from p53 −/− mice but not from wild-type, bax −/−, bak −/−, or bax −/− bak −/− mice. Whether these findings can be extrapolated to other cell types and additional death stimuli was not known. Here we determined that Bax and/or Bak were not essential for p53 to suppress oncogenic transformation which is likely mediated in all or in part by apoptosis. The release of cytochrome c in response to the overexpression of tBid is also inhibited in bax −/− bak −/− cells (), suggesting that these proteins are essential regulators of apoptotic mitochondrial function in response multiple stimuli. Raschyot deflektora cagi. E1A expression in primary kidney epithelial cells induces p53-dependent apoptosis that must be inhibited for transformation to occur (,, ).
