PGC1α/SIRT3-Mediated Oxidative Stress and Downregulation of NLRP3 Expression by Sodium Thiosulfate Pre- and Post-Treatment Accelerates Recovery from Ischemia–Reperfusion-Induced Acute Kidney Injury

Background

Renal ischemia–reperfusion injury (IRI) is the leading cause of acute kidney injury (AKI). It is associated with reduced blood flow as encountered in vascular surgery, including aortic aneurysm repair and kidney transplantation. In this study, we investigated whether pre- and/or post-administration of sodium thiosulfate (STS), an FDA-approved hydrogen sulfide donor drug, attenuated IRI-induced AKI in rats.
