Fig. 9. The effect of different treatments on chicken primary myocardial cells exposed to heat stress. (A) The effect of heat stress (HS) on cell viability. (B) The effect of HS on cell apoptosis rate. (C) The effect of HS on cellular reactive oxygen species (ROS) level. The difference of the data of cells with different treatments (excluding the data of untreated cells) vs. that of heat-stressed cells are indicated by ^*p < 0.05 and by ^**p < 0.01. The difference of the data of cells treated by acetylsalicylic acid (ASA)+heat stress (HS) and geldanamycin (GA)+HS vs. that of cells treated by GA+ASA+HS is indicated by ^†p < 0.05 and by ^††p < 0.01.
