Impaired endoplasmic reticulum (ER) and mitochondrial function has been implicated in many of the obesity-induced etiology of insulin resistance and type 2 diabetes. However, the underlying molecular mechanisms remain to be fully elucidated. We have identified Disulfide bond A oxidoreductase-like protein or DsbA-L as a critical regulator of adiponectin assembly and secretion in adipocytes (Liu et al (2008) Proc. Nat.Acad. Sci. USA, 105, 18302-07). DsbA-L expression in adipose tissues is significantly reduced in obese human subjects and animal models of obesity.
