Differential roles of insulin receptor substrates in brown adipocyte differentiation.
Insulin promotes adipocyte differentiation via a complex signaling network involving multiple insulin receptor substrates (IRSs). In cultured brown preadipocytes, expression of IRS-1 and IRS-2 mRNAs and proteins was at relatively high levels before and after differentiation into mature fat cells, while IRS-3 transcript was not detectable in preadipocytes but increased during the course of diffe...
متن کاملThe Role of Nrf2: Adipocyte Differentiation, Obesity, and Insulin Resistance
Metabolic diseases, such as type 2 diabetes and obesity, are increasing globally, and much work has been performed to elucidate the regulatory mechanisms of these diseases. Nuclear factor E2-related factor 2 (Nrf2) is a basic leucine zipper transcription factor that serves as a primary cellular defense against the cytotoxic effects of oxidative stress. Recent studies have proposed a close relat...
متن کاملAdiponectin promotes adipocyte differentiation, insulin sensitivity, and lipid accumulation.
Adiponectin is secreted from adipocytes, and low circulating levels have been epidemiologically associated with obesity, insulin resistance, type 2 diabetes, and cardiovascular disease. To investigate whether adiponectin could exert autocrine effects in adipocytes, we expressed the adiponectin gene in 3T3-L1 fibroblasts. We observed that 3T3-L1 fibroblasts expressing adiponectin have a fast gro...
متن کاملThioredoxin reductase 1 suppresses adipocyte differentiation and insulin responsiveness
Recently thioredoxin reductase 1 (TrxR1), encoded by Txnrd1, was suggested to modulate glucose and lipid metabolism in mice. Here we discovered that TrxR1 suppresses insulin responsiveness, anabolic metabolism and adipocyte differentiation. Immortalized mouse embryonic fibroblasts (MEFs) lacking Txnrd1 (Txnrd1(-/-)) displayed increased metabolic flux, glycogen storage, lipogenesis and adipogene...
متن کاملAdipocyte Differentiation
M.E. Symonds (ed.), Adipose Tissue Biology, DOI 10.1007/978-1-4614-0965-6_2, © Springer Science+Business Media, LLC 2012 Abstract Adipocyte differentiation is a highly controlled process that has been extensively studied for the last 25 years. Two different kinds of in vitro experimental models, essential in determining the mechanisms involved in adipocyte proliferation, differentiation and adi...
