Astaxanthin attenuates PM2.5-induced H9C2 cells injury. H9C2 cells were treated with different concentrations of AST (A), PM2.5 (B), and Fer-1 (C) for 24 h. The cell viability was detected by CCK8 assay. D Cell viability of H9C2 cells treated with PM2.5, AST and Fer-1. The activities of SOD (E) and LDH (F) in the H9C2 cells treated with PM2.5, AST and Fer-1. Values are expressed as mean ± SEM (n = 6). *p < 0.05 difference from the control group; **p < 0.001 difference from the control group; #p < 0.05 difference from the PM2.5 exposure group; and ##p < 0.001 difference from the PM2.5 exposure group
