Overcoming Basal Autophagy, Kangai Injection Enhances Cisplatin Cytotoxicity by Regulating FOXO3a-Dependent Autophagic Cell Death and Apoptosis in Human Lung Adenocarcinoma A549/DDP Cells

Figure 4

Combination of KAI- and cisplatin-triggered autophagy induction in A549/DDP cells. (a) A549/DDP cells were treated with KAI for 2 h; then, cisplatin (10 μM) was added for combined treatment for another 24 h. Staining with LC3 autophagy immunofluorescence and DAPI in A549/DDP cells, observed by confocal microscopy. Red: LC3; blue: DAPI. (b) Western blot showed autophagy-related proteins (Beclin 1, LC3 II, and p62). β-Actin was the loading control. (c) A549/DDP cells were treated with 10 nM of Bafilomycin A1 for 24 h and then cotreated with KAI and cisplatin for 24 h. Every experiment result was repeated ≥3 times, and results are presented using values ().
