Figure 1. IFC-305 treatment prevented I/R induced kidney injury (* P value < 0.05, vs control group; # P value < 0.05, vs. I/R group). A: H&E staining showed an increased level of renal injury in I/R rats, while the IFC-305 treatment alleviated the severity of I/R-induced renal injury (magnification, x200; arrow denotes injured renal tubules). B: The level of creatinine was increased in I/R rats and reduced by IFC-305 treatment.

Figure 2. Up-regulation of Hcy and down-regulation of CSE in the renal tissue and blood of I/R rats (* P value < 0.05, vs Control group; # P value < 0.05, vs. I/R group). A: Hcy concentration was elevated in the renal tissue of I/R rats and suppressed by subsequent IFC-305 treatment. B: Hcy concentration was elevated in the peripheral blood of I/R rats and suppressed by subsequent IFC-305 treatment. C: ELISA analysis showed that the decreased CSE activity in the renal tissue of I/R rat was restored by IFC-305 treatment. D: qPCR analysis showed that the decreased CSE mRNA expression in the renal tissue of I/R rat was restored by IFC-305 treatment. E: Western blot analysis showed that the decreased CSE protein expression in the renal tissue of I/R rat was restored by IFC-305 treatment.

Figure 3. IFC-305 reduced the abnormally high level of DNA methylation of the CSE promoter in the renal tissue of I/R rats. The level of DNA methylation of CSE promoter was enhanced in the renal tissue of I/R rats and repressed by subsequent IFC-305 treatment.
