A: administration of AMI-1 attenuates renal fibrosis in obstructed kidneys. Photomicrographs illustrate Masson trichrome staining of kidney tissue (magnification: ×200). B: the Masson trichrome-positive tubulointerstitial area relative to the whole area from 10 random cortical fields was analyzed. Data are presented as means ± SD; n = 6. **P < 0.01 vs. the sham control group or other groups as indicated. C: photomicrographs illustrating protein arginine methyltransferase 1 (PRMT1) expression in the kidney. Scale bar = 100 μm. UUO, unilateral ureteral obstruction.
