Fig. 1: Acute kidney injury induced by renal ischemia and reperfusion.

The levels of serum creatinine (a), miR-21 (b), GAS5 (c), TSP-1 mRNA (d), and TSP-1 protein (f) in mice subjected to renal ischemia for 35 min, followed by various reperfusion time. e Representative image of ISH for miR-21 and TSP-1 (photographed at ×20 magnification). g Histopathological changes (×20 magnification) and apoptosis in mice kidneys induced by renal ischemia and reperfusion (×40 magnification) evaluated by the TUNEL method. N = 4, *P < 0.05, **P < 0.01 vs. the Sham group. Scale bars, 100 μm.
