Minocycline inhibited LPS-induced oxidative stress in vitro. (A) ROS kit was used to evaluated oxidative stress levels in H9c2 cells. (B–D) The levels of MDA, SOD, and GSH in H9c2 cells were detected by kit. (E) Representative Western blot bands of SOD-1 and SOD-2 and (F,G) their statistical graphs. Data were presented as mean ± SD; n = 3; ns: statistically non-significant; *P < 0.05, **P < 0.01, ***P < 0.001 vs. control group; #P < 0.05, ##P < 0.01, ###P < 0.001 vs. LPS group.
