In vivo, MBD2 LysMcre attenuated unilateral ureteral obstruction (UUO) and ischemia/reperfusion (I/R)-induced renal fibrosis via downregulation of G0S2, which was demonstrated by the downregulation of fibronectin (FN), collagen I and IV, α-SMA, G0S2. This evidence concerns the gene ACTA1 and Ureteral obstruction.
