OA treatment enhanced formation of autophagic vacuoles as revealed by monodansylcadaverine (MDC) staining. At the same time, increasing punctuate distribution of microtubuleassociated protein 1 light chain 3 (LC3) and an increasing ratio of LC3-II to LC3-I werealso triggered by OA incubation. In addition, OA-induced cell death was signifi cantly inhibited by autophagy inhibitors 3-methyladenine (3-MA) and chloroquine (CQ) pretreatment. And we found out that OA can suppress the PI3K/Akt1/mTOR... -
