The post hoc Tukey test revealed that in animals without AKI, the ER and TR diets increased renal Bcl-2 compared to the CTL (P < 0.05), IF and HF groups (P < 0.001), and the HF diet decreased this protein in comparison with the CTL group (P < 0.05) (Fig. 4). Here, BCL2 is linked to acute kidney injury.
