Limonin improves cell viability of H9C2 cells suppressed by DOX treatment. (a) Cell viability of H9C2 cells was evaluated after being treated with different concentrations of DOX. (b) Cell viability of H9C2 cells was determined after being treated with different concentrations of limonin or limonin plus DOX. (c) LDH activity was detected in H9C2 cells with DOX treatment as well as limonin or not. (d) CK level was measured in H9C2 cells with DOX treatment as well as limonin or not. *p < 0 05, **p < 0 01 vs control
