Stearoyl-CoA desaturase: a vital checkpoint in the development and progression of obesity

Poudyal, Hemant and Brown, Lindsay (2011) Stearoyl-CoA desaturase: a vital checkpoint in the development and progression of obesity. Endocrine‚ Metabolic and Immune Disorders - Drug Targets, 11 (3). pp. 217-231. ISSN 1871-5303


Stearoyl-CoA desaturase 1 (SCD-1) is the rate-limiting enzyme that catalyses the conversion of saturated to monounsaturated fatty acids. Increased SCD-1 expression and activity has been implicated in cancer, cardiovascular diseases, insulin resistance and obesity. Studies with humans, wild-type rodents, knock-out mice and cells in culture show that SCD-1 inhibition decreases lipogenesis and increases GLUT4-mediated glucose uptake in skeletal muscle. In this review, we will evaluate the role of SCD-1 as a homeostatic check-point between glucose and fatty acid metabolism in the development and progression of obesity. In addition to the role of SCD-1 in glucose and fatty acid metabolism, we will also discuss the expression and regulation of SCD-1, its specific interactions with inflammatory responses and PPARs, the role of SCD-1 derived MUFAs in obesity and the relevance of SCD desaturation index as a predictor of obesity and metabolic syndrome. Additionally, we will explore the prospects of SCD-1 as a potential drug target for the management of obesity and related disorders.
