Fig. 2. The induction of Hsp90 by aspirin (acetylsalicylic acid [ASA]) in chicken primary myocardial cells. (A) The effect of ASA on cell viability. (B) The effect of ASA at different concentrations on Hsp90 level of chicken primary myocardial cells. (C) The effect of ASA at 1 mg/mL on Hsp90 level of chicken primary myocardial cells. (A and B) The difference of data at different concentrations vs. that at 0 mg/mL is indicated by ^*p < 0.05 and by ^**p < 0.01. (C) The difference of the data at different times vs. that at 0 h is indicated by ^*p < 0.05 and by ^**p < 0.01. OD, optical density.
