Role of nuclear receptor corepressor RIP140 in metabolic syndrome

Obesity and its associated complications, which can lead to the development of metabolic syndrome, are a worldwide major public health concern especially in developed countries where they have a very high prevalence. RIP140 is a nuclear coregulator with a pivotal role in controlling lipid and glucose metabolism. Genetically manipulated mice devoid of RIP140 are lean with increased oxygen consumption and are resistant to high-fat diet-induced obesity and hepatic steatosis with improved insulin sensitivity. Moreover, white adipocytes with targeted disruption of RIP140 express genes characteristic of brown fat including CIDEA and UCP1 while skeletal muscles show a shift in fibre type composition enriched in more oxidative fibres. Thus, RIP140 is a potential therapeutic target in metabolic disorders. In this article we will review the role of RIP140 in tissues relevant to the appearance and progression of the metabolic syndrome and discuss how the manipulation of RIP140 levels or activity might represent a therapeutic approach to combat obesity and associated metabolic disorders. This article is part of a Special Issue entitled: Translating nuclear receptors from health to disease.     

Association between chemerin rs17173608 and vaspin rs2236242 gene polymorphisms and the metabolic syndrome,a preliminary report

Metabolic syndrome (MeS) is associated with increased risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease. There is some evidence indicating that adipokines play a role in the development of MeS. The present study was aimed to investigate the impact of chemerin rs17173608 and vaspin rs2236242 gene polymorphisms with the risk of MeS in a sample of Iranian population.
