5-HT1F receptor regulates mitochondrial homeostasis and its loss potentiates acute kidney injury and impairs renal recovery.

ABSTRACT: Our laboratory previously reported that agonists of the 5-hydoxytryptamine 1F (5-HT1F) receptor induce renal mitochondrial biogenesis (MB) and that stimulation of the 5-HT1F receptor following ischemia/reperfusion (I/R)-induced acute kidney injury (AKI) accelerated the recovery of renal function in mice. The goal of this study was to examine the contribution of the 5-HT1F receptor in the regulation of renal mitochondrial homeostasis and renal function in naïve and injured mice. Although 5-HT1F receptor knockout (KO) mice were healthy and fertile, and did not exhibit renal dysfunction, renal mitochondrial DNA copy number and mitochondrial fission gene expression increased at 10 wk of age. The 5-HT1F receptor KO mice exhibited greater proximal tubular injury and diminished renal recovery aft
