Effects of reintroduction or inhibition of ALDH2 on the cellular viability of PC12 cells exposed to OGD injury. A and B. OGD injury reduced ALDH2 protein levels as shown in the Western blot image. GAPDH was used as a loading control. Quantitative data of ALDH2 levels are shown. C and D. Overexpression of ALDH2 was achieved by plasmid transfection and verified by Western blot. E and F. ALDH2 siRNA reduces ALDH2 levels in the primary cortical neurons and PC12 cell lines. G -J. The effect of overexpression or knockdown of ALDH2 on cell survival and LDH leakage of the primary cortical neurons and PC12 cells under OGD conditions. K and LALDH2 overexpression or inhibition alleviated or aggravated mitochondria-derived ROS production. M-P. The level of MDA and 4-HNE in the primary cortical neurons and PC12 cells detected by ELISA kits.
