Abstract:
The rising global incidence of diabetes mellitus (DM) and hyperuricemia presents a growing challenge to public health systems worldwide. Urate transporter-1 (URAT1), a key renal urate transporter, has emerged as a promising therapeutic target for managing DM and its associated complications. Growing evidence suggests that URAT1's role in metabolic disorders extends beyond its function in the kidney. Specifically, URAT1 can influence uric acid metabolism in multiple tissues including neural, hepatic, vascular smooth muscle, cardiac, and adipose tissue, thereby contributing to insulin resistance, inflammation, and end-organ damage. In this review, we comprehensively examine the extra-renal functions of URAT1, focusing on its roles in the hematopoietic system, heart, liver, adipose tissue, and vascular endothelium in the context of DM. This analysis highlights the multi-organ mechanisms through which URAT1 exerts its effects, offering valuable insights into its potential as a therapeutic target for this complex systemic metabolic disorder.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
