Figure 5. Klotho is critical for the renal protection by HDAC inhibition.

Figure 5

Mice receiving siRNA-control or siRNA-Klotho underwent TSA, adenine or TSA plus adenine treatments for 6 weeks (n = 6 in each group). (A) Renal Klotho protein levels from siRNA-control or siRNA-Klotho-injected mice were examined (6 weeks, three randomly selected samples from each group were shown) by Western blotting. (B) Representative Masson’s trichrome staining of kidney sections from siRNA-control or siRNA-Klotho-injected control, TSA, adenine and TSA-treated adenine mice (6 weeks, n = 6 in each group). (C) Quantifications of renal interstitial fibrosis (the percentage of blue-colored cortex area over the whole cortex field from Masson’s trichrome-stained sections) from all mice in Fig. 5B. (D) Renal expressions of BMP-7 and phosphorylated Smad3 were examined by Western blotting (Two randomly selected samples were shown). (E) Quantifications of BMP-7 and P-Smad3 in Fig. 5D (n = 6). (F) Average serum levels of phosphorus (P), iPTH, FGF23 and Calcium (Ca), from all mice (n = 6). Data are presented as the mean ± SD. *P < 0.05, **P < 0.01 versus control, #P < 0.05, ##P < 0.01 versus adenine treatment in siR-control mice; ΔP < 0.05, ΔΔP < 0.01 versus control in siR-Klotho mice.
