Renal fibrosis is the final common pathway of chronic kidney disease (CKD), and
no effective medication is available clinically for managing its progression.
Metformin was initially developed as an anti-diabetic drug and recently gained
attention for its potential in the treatment of other diseases. In this study, we
investigated its effects on renal fibrosis in a mouse model of unilateral
ureteral obstruction (UUO) in vivo and in angiotensin II (Ang II)-treated renal
fibroblast NRK-49F cells in vitro. Our data showed that UUO induced renal
fibrosis and combined with the activation of ERK signaling, the upregulation of
fibronectin, collagen I, and transforming growth factor-? (TGF-?). The
administration of metformin inhibited the activation of ERK signaling and
attenuated the production of extracellular matrix (ECM) proteins and collagen
deposition in the obstructed kidneys. In cultured renal fibroblasts, Ang II
increased the expression of fibronectin and collagen I and also activated ERK
signaling and TGF-? in a time-dependent manner. Pretreatment of the cells with
metformin blocked Ang II-induced ERK signaling activation and ECM overproduction.
Our results show that metformin prevents renal fibrosis, possibly through the
inhibition of ERK signaling, and may be a novel strategy for the treatment of
renal fibrosis.
