Renal fibrosis is a common feature of all progressive chronic kidney diseases. Sirtuin 3 (SIRT3) is one of the mitochondrial sirtuins, and plays a role in the regulation of mitochondrial biogenesis, oxidative stress, fatty acid metabolism, and aging. Recently, honokiol (HKL), as a pharmaceutical SIRT3 activator, has been observed to have a protective effect against pressure overload-induced cardiac hypertrophy by increasing SIRT3 activity. In this study, we investigated whether HKL, as a SIRT3 activator, also has protective effects against unilateral ureteral obstruction (UUO)-induced renal tubulointerstitial fibrosis through SIRT3-dependent regulation of mitochondrial dynamics and the nuclear factor-κB (NF-κB)/transforming growth factor-β1 (TGF-β1)/Smad signaling pathway. We found that HKL decreased the UUO-induced increase in tubular injury and extracellular matrix (ECM) deposition in mice. HKL also decreased myofibroblast activation and proliferation in UUO kidneys and NRK-49F cells. Finally, we showed that HKL treatment decreased UUO-induced mitochondrial fission and promoted mitochondrial fusion through SIRT3-dependent effects. In conclusion, activation of SIRT3 via HKL treatment might have beneficial effects on UUO-induced renal fibrosis through SIRT3-dependent regulation of mitochondrial dynamics and the NF-κB/TGF-β1/Smad signaling pathway.

Background: Intestinal fibrosis is the major complication of Crohn’s disease (CD). There are no other good treatments for CD except surgery and remains a refractory disease. Calycosin (CA), the active component of astragalus membranaceus, has been reported the potential effect on lung fibrosis and renal fibrosis. In this study, we aim to explore the effect of CA on intestinal fibrosis in vitro and the possible signal pathway. Methods: The antifibrotic effect of CA is investigated in human intestinal fibroblasts (CCD-18Co) cells induced by transforming growth factor-β1 (TGF-β1). MTT method was used to screen the concentration of CA. Real-time polymerase chain reaction and western blot analysis were used to evaluate the expression of α-smooth muscle actin (α-SMA), collagen I, and TGF-β/Smad pathway. Results: The results showed that the concentration of CA was 12.5, 25, 50 μmol/L. CA could inhibit the expression of α-SMA and collagen I. In addition, CA regulated the expression of TGF-β/Smad signaling pathway. Conclusion: This study demonstrated that CA could inhibit the activation of CCD-18Co cells and reduce the expression of extracellular matrix. Our study highlighted that CA-inhibited TGF-β/Smad pathway through inhibiting the expression of p-Smad2, p-Smad3, Smad4, and TGF-β1 and raised the Smad7 expression. Therefore, CA might inhibit intestinal fibrosis by inhibiting the TGF-β/Smad pathway.
