Fig. 2From: Vitexin induces apoptosis through mitochondrial pathway and PI3K/Akt/mTOR signaling in human non-small cell lung cancer A549 cellsVitexin induces apoptosis in A549 cells. a The apoptosis of A549 cells following 48 h of vitexin treatment was detected by Annexin V-FITC/PI double staining. b The expression levels of apoptotic-related proteins in A549 cells following 48 h of vitexin treatment were detected by western blot analysis. *P < 0.05 versus vehicle-treated cellsBack to article page
