Fig. 6From: Regulation of connective tissue growth factor expression by miR-133b for the treatment of renal interstitial fibrosis in aged mice with unilateral ureteral obstructionmiR-133b inhibited renal interstitial fibrosis in aged mice with UUO. Mice with UUO were administered with an intravenous injection of miR-133b or NC-miRNA transfection complex. A Real-time PCR analysis of miRNA-133b expression. B Masson’s trichrome and PAS staining of renal tissues as observed under a light microscope (× 100). a: P < 0.05 versus the sham group; b: P < 0.05 versus UUO+NC-miR groupBack to article page
