Pemafibrate ameliorates renal injury through induction of FGF21 and ketone body production in male mice.

ABSTRACT: Chronic kidney disease is a life-threatening disease worldwide. PPARα is a crucial transcriptional regulator of lipid metabolism and inflammation. Here, we examine whether a novel selective PPARα modulator, pemafibrate modulates renal injury in a model of unilateral ureteral obstruction (UUO). Administration of pemafibrate to wild-type (WT) mice led to reduction of renal dysfunction and fibrosis after UUO with accompanying increases in plasma levels of fibroblast growth factor (FGF) 21 and ketone body β-hydroxybutyrate (BHB). Treatment of WT mice with FGF21 or BHB precursor resulted in attenuation of renal fibrotic and inflammatory responses after UUO. Treatment of proximal tubular cells with FGF21 or BHB reduced expression of epithelial-mesenchymal transition markers. These findings sugge
