Abnormal hepatic lipid metabolism is a major contributor to non-alcoholic fatty liver disease (NAFLD). NAFLD is strongly associated with the development of insulin resistance and type 2 diabetes.

SerpinA3N (serine (or cysteine) peptidase inhibitor clade A member 3N) is a member of the serpin family of proteins, a group of proteins that inhibit serine proteases. It has been shown to play a role in glucocorticoid-induced myopathy, and is upregulated by a high fat diet.

In this paper, Tran et al. identify the role of serpinA3N in governing NAFLD progression and glucose homeostasis. They characterise a serpinA3N hepatic knockout, detailing protected glucose tolerance and insulin sensitivity. This model also demonstrates resistance to diet-induced obesity. The study shows, for the first time, that co-ordination of leptin and insulin may, in part, be driven by serpinA3N, and that this protein may have an important role in the manifestation of NAFLD.
