Di-tert-butyl dicarbonate (BOC-2) treatment could deteriorate renal function and pathological injury after ischemic injury in non-diabetic (ND) mice. Male C57BL/6J mice were subjected to sham operation or 30 min of bilateral renal ischemia followed by 48 h of reperfusion (I/R48). For the BOC-2 group, BOC-2 was given at a dose of 5 μg/kg intraperitoneally 30 min before renal ischemia–reperfusion. (A,B) Serum creatinine and blood urea nitrogen (BUN). (C) Hematoxylin and eosin (HE) staining for renal tissues. Scale bar, 100 μm. (D) TUNEL assay to reveal apoptosis of renal tissues. Scale bar, 50 μm. (E) Semi-quantification for renal tissue damage. (F) Statistical analysis for TUNEL-positive cells. All the data are shown as the mean ± SD (n = 6). *p < 0.05 vs. the relevant ND + I/R group.
