Summary

Obestatin was identified as an anorexigenic peptide with an action on the food intake. The first studies have shown that the obestatin reduced food intake and body weight. It has also been considered to be an antidiabetic peptide by positively influencing glucose and lipid metabolism. Obestatin reduces the apoptosis and promote the proliferation of B-cells and human pancreatic islets. Due to heterogeneity of these sources, obestatin has many different functions. Indeed obestatin could have a function in the regulation of blood pressure and its plasmatic concentration increases in case of hypertensive patients.
