Sodium/glucose cotransporter 2

The sodium/glucose cotransporter 2 (SGLT2) is a protein that in humans is encoded by the SLC5A2 (solute carrier family 5 (sodium/glucose cotransporter)) gene.[5]

SGLT2 is a member of the sodium glucose cotransporter family which are sodium-dependent glucose transport proteins. SGLT2 is the major cotransporter involved in glucose reabsorption in the kidney.[6]

SGLT2 inhibitors for diabetes

SGLT2 inhibitors are called gliflozins. They lead to a reduction in blood glucose levels. Therefore, SGLT2 inhibitors have potential use in the treatment of type II diabetes. Gliflozins enhance glycemic control as well as reduce body weight and systolic and diastolic blood pressure.[7] The gliflozins canagliflozin, dapagliflozin, and empagliflozin may lead to euglycemic ketoacidosis.[8][9] Other side effects of gliflozins include increased risk of (generally mild) genital infections, such as candidal vulvovaginitis [10] and Fournier gangrene.[11]

Clinical significance

Mutations in this gene are also associated with renal glucosuria.[12]

Model organisms

Model organisms have been used in the study of SLC5A2 function. A conditional knockout mouse line, called Slc5a2tm1a(KOMP)Wtsi[18][19] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[20][21][22]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[16][23] Twenty two tests were carried out on homozygous mutant mice and one significant abnormality was observed: males displayed increased drinking behaviour.[16]
