To determine whether increased lipogenesis contributes to human obesity, we measured (postabsorptive state), in lean and obese subjects, lipid synthesis (deuterated water method) and the mRNA concentration (RT-competitive PCR) in subcutaneous adipose tissue of fatty acid synthase (FAS) and sterol regulatory element-binding protein (SREBP)-1c. Before energy restriction, obese subjects had an inc...
Conjugated linoleic acid (CLA) refers to the positional and geometric dienoic isomers of linoleic acid. The dietary intake of CLA has been associated with changes in lipid metabolism. The aim of the present work was to assess the effects of the two main isomers of CLA on sterol regulatory element binding protein (SREBP)-1a and SREBP-1c mRNA levels, as well as on mRNA levels and the activities o...
The sterol regulatory element binding protein 1 (SREBP-1) is regarded as a major factor involved in the nutritional regulation of lipogenesis. The aim of the present work was to demonstrate its involvement in the response of key genes of glucose and lipid metabolism in liver, adipose tissue, and skeletal muscle during fasting and refeeding. The regulation of hexokinase-2 (HKII) was investigated...
Non-alcoholic fatty liver disease (NAFLD) is characterized by hepatic triglyceride accumulation, ranging from steatosis to steatohepatitis and cirrhosis. NAFLD is a risk factor for cardiovascular diseases and is associated with metabolic syndrome. Antihyperlipidemic drugs are recommended as part of the treatment for NAFLD patients. Although fibrates activate peroxisome proliferator-activated re...
A region of the rat FAS (fatty acid synthase) promoter has been defined as being responsible for RA (retinoic acid) responsiveness. The defined promoter region is devoid of canonical RA-response elements but contains cis-elements binding generalized and specific transcription factors that mediate the dietary response of FAS. Our results are consistent with SREBP-1c (sterol-regulatory-element-bi...
