(A) The kidneys were harvested at 0, 3, 7, 14 days after surgery with left ureteral ligation and then homogenized. Kidney tissue lysates were subjected to immunoblot analysis with antibodies against α-SMA, Collagen1, Fibronectin, HDAC8 and tubulin, respectively. Expression levels of α-SMA, Collagen1, Fibronectin, HDAC8 and Tubulin were performed were quantified by densitometry and the levels of α-SMA (B), Collagen1 (C), Fibronectin (D), HDAC8 (E) and Cortactin (G) were normalized with Tubulin. Acetyl-Cortactin (F) was normalized with Cortactin. Values are the means ± S.D (n = 6). Means with different superscript letters (a-d) are significantly different from one another (P<0.05). (H) Photomicrographs illustrating HDAC8 (red), α-SMA (green) and nuclei (blue) immunofluorescent staining of kidney tissue after UUO treatments (200X). Scale bar: 50 μM.
