Research Abstract

Vaspin is a novel adipocytokine, which was identified from visceral adipose tissues in obese rats. The injection of recombinant vaspin into obese mice and experiments using vaspin transgenic and knockout mice revealed that vaspin is a compensatory factor for insulin resistance in metabolic syndrome. Vaspin circulated in the sera of human subjects and it positively correlated with body mass index and degree of insulin resistance. Serum levels of vaspin were higher in patients with type 2 diabetes compared with normal healthy subjects. The regulation of serum concentration of vaspin differed from leptin and adiponectin and vaspin may be a new therapeutic target for metabolic syndrome.
