MASM induces autophagy through PI3K/Akt/mTOR, Erk1/2 and p38 signaling pathway. a Indicated cancer cell lines were treated with different concentrations of MASM (0, 30, 60 μg/ml) for 24 h, then expression levels of p-Erk1/2, Erk1/2, p-p38, and p38 were carried out by western blot. b Indicated cancer cell lines were treated with 60 μg/ml MASM for different times (0,8,16,24 h) and the relative expression levels of p-Erk1/2, p-p38 compared to GAPDH. c Expression of p-Erk, p-38 and LC3B-II in MDA-MB-231 treated with MASM alone or co-treatment with Erk1/2 inhibitor PD184352 (2 μM) or p38 inhibitor SB203580 (10 μM). Data were representative of three independent experiments
