PIF Treatment Inhibited the Expressions of Collagen I, Collagen IV, Fibronectin, α-SMA, and p53 Detected by Immunoblotting
(A) Western blot analysis of collagen I, collagen IV, fibronectin, α-SMA, p53, and β-actin by using the specific antibodies. (B) Densitometric quantification of western blot bands. Data are expressed as means ± SD (n = 8). #p < 0.05, saline-treated db/db group versus saline-treated db/+ group; *p < 0.05; PIF-treated db/db group versus saline-treated db/db group.
