Description
Omentin, also called omentin-1, is a visceral fat depot-specific secretory protein.1 It is expressed predominantly in visceral adipose tissue but also expressed in stromal vascular cells, but not fat cells. Omentin does not affect basal but enhanced insulin-stimulated glucose uptake. Its expression is down-regulated by insulin and glucose.2 Omentin enhances the effect of insulin on the regulation of sugar within the body and therefore may be a factor in causing abdominal obesity and related diseases, such as Type 2 diabetes.3
