(A) H1299 cells stably expressing GFP-LC3 were incubated for the indicated times in EBSS in the presence of 50 μM zVAD‐FMK and analysed by immunofluorescence for cyt c or active BAX (6A7 epitope). As a positive control, cells were infected with 5 p.f.u. per cell Ad HA‐tBID for 7 h. Data are expressed as the average of three experiments±s.d.
