a KB cells were transfected and the level of LC3 was analyzed by Western immunoblotting. Densitometry was performed on the original blots, and the ratio of LC3-II/β-tubulin in control cells was 1. b Western immunoblotting analysis of P62, Beclin-1, Cleaved caspase-3 and IL-24 in KB cells. c Semiquantitive analysis of P62, Beclin-1 and Cleaved caspase-3 in Kb cells. Compared with the control group denoted by “*” (p < 0.05). Compared with the IL-24-treated group denoted by “#” (p < 0.05). Values represent mean ± SD (n = 3)
