ALDH2 overexpression enhanced the proliferation of SW1353 cells induced by MIA. A Level of ROS in MIA-stimulated SW1353 cells was assessed with a commercial kit. B Expression of ALDH2 in SW1353 cells exposed to MIA was determined by means of western blot assay. C, D ALDH2 expression was tested with RT-qPCR and western blotting after transfection. E Cell viability was detected by a CCK-8 assay in MIA challenged SW1353 cells with ALDH2 overexpression. F Western blot analysis was adopted for the measurement of Ki67 and PCNA expression. *P < 0.05, **P < 0.01, ***P < 0.001
