The involvement of microRNA-668 (miR-668) in the onset and progression renal fibrosis remains unclear. To this end, we aimed to explore relevant mechanism miR-668 fibrosis. C57BL/6 J male mice were randomly divided into sham-operated, unilateral ureteral obstruction (UUO), UUO-fenofibrate groups. Based on transfection drug intervention, HK-2 cells blank control, TGF-β1, TGF-β1 + fenofibrate (PPARα agonist), mimics-NC, miR-668, mimics-NC fenofibrate, GW6471 inhibitor), pathological changes tissues observed by hematoxylin–eosin (HE) Masson staining. expression PPARα, PGC-1α, E-cadherin, Collagen III (Col III), α-SMA or was detected western blot, immunohistochemical analyses real-time quantitative polymerase chain reaction. regulatory effect PPARα verified dual-luciferase reporter assay. PGC-1α decreased UUO TGF-β1-induced cells, which improved fenofibrate. Compared non-transfected group, TGF-β1-stimulated increased Col miR-668-transfected group. assay indicated hsa-mir-668-3p PPARα. MiR-668 can target positively regulate PPARα/PGC-1α pathway alleviate
