Figure 1.

H9c2 cells were subjected to 12 h oxygen-glucose deprivation (OGD) followed by reperfusion for 3 h, 6 h, 12 h, 24 h. A. The cell viability of H9c2 cells after oxygen-glucose deprivation and reperfusion (OGD/R) assayed by Cell Counting Kit-8 (CCK-8). B. OGD/R induced H9c2 cell injury evaluated by lactate dehydrogenase (LDH) assay. C, D. Western blot assay showed the expression of thioredoxin-2 (Trx2) at the indicated time points during OGD/R. *P < 0.05 vs control, ***P < 0.001 vs control.
