Thiazolidinediones downregulate stearoyl-CoA desaturase 1 gene expression in 3T3-L1 adipocytes.
Thiazolidinediones (TZDs) are known to have potent increases of insulin sensitivity. Because peroxisome proliferator-activated receptor-gamma (PPAR-gamma), a receptor for TZDs, is mainly expressed in adipocytes, we tried to search the TZD-targeted genes in mouse 3T3-L1 adipocytes. By the mRNA differential display method, one band repressed by troglitazone was obtained, which corresponded to the...
متن کاملGlucose induces expression of stearoyl-CoA desaturase in 3T3-L1 adipocytes.
Stearoyl-CoA desaturase (SCD; EC 1.14.99.5) is a key enzyme in the synthesis polyunsaturated fatty acids. Liver and ose tissue are the predominant sites of SCD expression. Regulation of tic SCD by various nutritional and hormonal ors, such as insulin, dietary carbohydrates and polyunsaturated fatty s, has been well documented. Little is known, ver, about adipocyte SCD regulation despite high le...
متن کاملStearoyl-CoA Desaturase 1 Is a Key Determinant of Membrane Lipid Composition in 3T3-L1 Adipocytes
Stearoyl-CoA desaturase 1 (SCD1) is a lipogenic enzyme important for the regulation of membrane lipid homeostasis; dysregulation likely contributes to obesity associated metabolic disturbances. SCD1 catalyses the Δ9 desaturation of 12-19 carbon saturated fatty acids to monounsaturated fatty acids. To understand its influence in cellular lipid composition we investigated the effect of genetic ab...
متن کاملRegulation of stearoyl-CoA desaturase 1 mRNA stability by polyunsaturated fatty acids in 3T3-L1 adipocytes.
The effects of arachidonic acid (20:4, n-6) and other fatty acids on the expression of stearoyl-CoA desaturase gene 1 were investigated in fully differentiated 3T3-L1 adipocytes. Treatment of 3T3-L1 adipocytes with arachidonic acid resulted in a decrease in stearoyl-CoA desaturase (Scd) enzyme activity and scd1 mRNA. Arachidonic acid did not alter the transcription of the scd1 gene, whereas the...
متن کاملInvestigation of (Stearoyl-CoA Desaturase 1) SCD1 Gene Polymorphism in Khuzestan Buffalo Population Using PCR-RFLPMethod
Stearoyl-CoA desaturase (SCD) is a rate-limiting enzyme in the biosynthesis of monounsaturated fatty acids (MUFA). A number of studies support the hypothesis that SCD gene regulation and polymorphism may affect fatty acid composition and fat quality in meat and milk. Single nucleotide polymorphisms in the coding region of the bovine stearoyl-CoA desaturase gene have been predicted to result in ...
