(A) H1299 cells stably expressing GFP-LC3 were infected with 10 p.f.u. per cell of either Ad LacZ or Ad Myc‐MCL‐1 for 24 h then incubated in EBSS for 4 h. Alternatively, cells were transfected with control or MCL‐1 siRNA 24 h before EBSS treatment. Cells were stained with an antibody against cyt c and analysed by immunofluorescence. Representative images are shown. Scale bars=50 μm.
