CASP9 and infection: Besides, Bax and Bim expression was both decreased in the four overexpression groups by CPCs-Ex at 24 and 48 h p.i. But at the late stage of infection, the cleavage of caspase-3 was promoted and the cleavage of caspase-9 was repressed in Akt2, 4EBP1, and p70S6K overexpression groups (supplementary file 7, P < 0.05).
