PARP1 inactivation reduces α-SMA expression during the period of kidney interstitial fibrosis after IRI. a Expression of α-SMA was detected by immunofluorescent stain on kidney sections at 16 days after IRI. Scale bars indicate 50 μm. b Percentage of α-SMA-positive area on the kidney sections. Error bars represent SD (n = 5). # P < 0.05 versus vehicle
