Alteration in membrane lipid order and composition in metabolically hyperactive fatty rat adipocytes

Autor: M Lavau, Phillipe Guesnet, Michèle Guerre-Millo, Georges Durand, Colette Guichard

Lipids, Springer Verlag, 1994, 29 (3), pp.205-209

We have previously shown that adipose cells from young genetically obese Zucker rats are characterized by very high metabolic activity together with an increase in a wide range of membrane-mediated functions. The aim of the present study was to exami

Expression of glucose transporters (GLUT 1 and GLUT 4) in primary cultured rat adipocytes: Differential evolution with time and chronic insulin effect

Autor: Colette Guichard, Isabelle Hainault, Eric Hajduch, M Lavau, Michèle Guerre-Millo

Publikováno v: Journal of Cellular Biochemistry. 49:251-258

We previously reported that in cultured adipose cell lines insulin increased selectively the expression of Glut 1, in contrast to in vivo regulation where variations in insulinemia have been shown to affect only GLUT 4. We have addressed here the que

Genetic regulation of fatty acid synthetase expression in adipose tissue: overtranscription of the gene in genetically obese rats

We have investigated the molecular mechanism of the overactivity of fatty acid synthetase (FAS) in adipose tissue from the genetically obese Zucker rat. Purified FAS from lean and obese rat adipose tissues displayed kinetics constants, molecular weig

International audience; The transcription factor sterol regulatory-element-binding protein-1c (SREBP-1c) plays a major role in the effect of insulin on the transcription of hepatic genes such as glucokinase and fatty acid synthase. We show here in cu

International audience; Phosphoenolpyruvate carboxykinase (PEPCK) is the rate-limiting enzyme of gluconeogenesis in the liver. PEPCK gene expression is controlled at the transcriptional level and is mainly regulated by hormones that are involved in g

International audience; Hepatic glucokinase plays a key role in glucose metabolism as underlined by the anomalies associated with glucokinase mutations and the consequences of tissue-specific knock-out. In the liver, glucokinase transcription is abso
