Advances in Urate Excretion and Urate Transporters in Hyperuricemia

Hyperuricemia is a heterogeneous disease caused by dysregulation of the homeostasis of urate production and excretion, which leads to the elevation of blood uric acid beyond the normal range. It has been found that three common genes ABCG2, SLC2A9 and SLC22A12 have a great influence on serum uric acid level in human body. Other urate transporter genes, such as SLC16A9, SLC22A6, SLC22A7, SLC22A8, SLC22A9, SLC22A11, SLC22A13 and ABCC4 also play a crucial role in the regulation of urate levels. This article reviews the urate transporters mentioned above that have been found to be related to the development of hyperuricemia, including uric acid reabsorption transporter and uric acid secretion transporter in kidney, uric acid transporter in intestine, aiming at providing theoretical and data support for future clinical treatment.
