摘要

The global incidence and prevalence of kidney diseases continue to rise, posing a serious public health challenge. SIRT6 is an NAD⁺-dependent histone deacetylase with broad essential regulatory roles across various pathophysiological processes, including DNA repair, chromatin accessibility, telomere stability, and glycolipid metabolism. As an epigenetic regulator specifically expressed in kidney tissues, SIRT6 serves as a central mediator of kidney homeostasis. Notably, accumulating evidence has implicated aberrant SIRT6 expression in the onset and development of various kidney diseases, such as acute kidney injury, diabetic kidney disease, hypertensive nephropathy, renal fibrosis, and renal cell carcinoma. In the present review, we provide an overview of the sirtuin family, systematically characterize the enzymatic activities and critical biological functions of SIRT6, and discuss its molecular mechanisms across various kidney diseases, focusing on its cell type-specific functions. We further summarize the latest research advances in SIRT6-targeted modulators for improving kidney diseases and analyze the challenges associated with their clinical application. Overall, we highlight SIRT6 as a highly promising novel target in the treatment and prevention of kidney diseases, with strong potential for clinical translation.
