Protective effects of baicalein on lysophosphatidylcholine (lysoPC)-induced cell death of rat H9c2 cells. (a) H9c2 cells were treated with lysoPC for 24 h. LysoPC (1 to 50 μM) dose-dependent decreased cell viability. (b) Baicalein attenuated lysoPC (50 μM)-induced cell death in a dose-dependent manner. Values represent mean ± S.E.M, n = 9. Control: H9c2 cells were placed in serum-free medium. ##
P < 0.01, versus control group; **P < 0.01 versus cells exposed to lysoPC alone.
