Tβ4 attenuates renal tubular cells apoptosis in the rat model of UUO. a Representative microphotographs of TUNEL staining in kidney sections. TUNEL is stained in red and nuclei are labeled by DAPI staining in blue. The sections are shown at an original magnification of 400. b Representative immunoblotting of cleaved caspase-3, Bax and Bcl-2. c, d and e Quantification of western blot. ^△ P < 0.01 vs. the sham group; ^# P < 0.05 vs. the UUO group; ^* P < 0.05 vs. the UUO+ low-dose Tβ4 group
