Abstract

C1q/TNF-related protein 1 (CTRP1), a conserved protein of the C1q family, plays a key role in cardiovascular and metabolic diseases. However, the role of CTRP1 in renal injury is unclear. The purpose of this study is to explore the role of CTRP1 in unilateral ureteral obstruction (UUO)-induced renal fibrosis and to elucidate the underlying mechanism. Using gene delivery system, CTRP1 was overexpressed in the kidney, then the mice were operated to induce UUO model after adenovirus transfection. It was found that the expression of CTRP1 in the renal tissue was decreased in mice after UUO. CTRP1 overexpression decreased the kidney function and kidney weight index. Moreover, CTRP1 reduced oxidative stress and renal collagen deposition in vivo. As expected, we found that CTRP1 activated AMP-activated kinase (AMPK) and decreased NOX4 expression, while silencing AMPKα1 abolished the protective effects of CTRP1 overexpression in mice after UUO. In conclusion, CTRP1 may protect against UUO-induced renal injury via AMPK/NOX4 signaling. Our results indicate that CTRP1 exhibits potential effects to treat renal fibrosis caused by UUO.
