Abstract
Bid, a member of the pro-apoptotic Bcl-2 protein family, is activated through caspase-8-mediated cleavage into a truncated form (p15 tBid) during TNF-α(tumor necrosis factor α)-induced apoptosis. Activated tBid can induce Bax oligomerization and translocation to mitochondria, triggering the release of cytochrome c, caspase-3 activation and cell apoptosis. However, it is debatable that whether Bid and tBid can interact directly with Bax in living cells. In this study, we used confocal fluorescence microscope, combined with both FRET (fluorescence resonance energy transfer) and acceptor photobleaching techniques, to study the dynamic interaction between Bid and Bax during TNF-α-induced apoptosis in single living cell. In ASTC-a-1 cells, full length Bid induced Bax translocation to mitochondria by directly interacting with Bax transiently in response to TNF-α treatment before cell shrinkage. Next, we demonstrated that, in both ASTC-a-1 and HeLa cells, Bid was not cleaved before cell shrinkage even under the condition that caspase-8 had been activated, but in MCF-7 cells Bid was cleaved. In addition, in ASTC-a-1 cells, caspase-3 activation was a biphasic process and Bid was cleaved after the second activation of caspase-3. In summary, these findings indicate that, FL-Bid (full length-Bid) directly regulated the activation of Bax during TNF-α-induced apoptosis in ASTC-a-1 cells and that the cleavage of Bid occurred in advanced apoptosis.
