During and after insulin-induced hypoglycemia, changes in levels of cerebral phosphatidylinositol (PI), phosphatidylinositol 4-phosphate (PIP), phosphatidylinositol 4,5-bisphosphate (PIP2), phosphatidic acid (PA), triacylglycerol (TAG), diacylglycerol (DAG), and free fatty acids (FFAs) as well as
Hypoglycemic coma induced by administration of a large dose of insulin, was accompanied by the increased rates of glycolysis, glycogenolysis, activity of lactate dehydrogenase, succinate dehydrogenase, isocitrate dehydrogenase, and increased concentration of glycogen. Under these conditions
OBJECTIVE
Liver X receptors (LXRs) are ligand-activated transcription factors that play an important role in regulation of hepatic lipid and carbohydrate metabolism. However, to date there is very few information on the role of LXRs in skeletal muscle. Moreover, it remains obscure whether LXR
The rate of incorporation of [U-14C]glucose and [u-14C]palmitate into the lipids of the pancreatic islets of obese-hyperglycaemic mice was examined. The following main observations were made. 1. Both glucose and palmitate were incorporated into lipids in the islets. The fraction of glucose utilized
Alcohol accounts for 4-6% of the average energy intake in most Western countries. Alcohol-induced hypoglycaemia is a well-known and feared complication in insulin-dependent diabetic subjects, but little attention has been paid to the impact of alcohol on carbohydrate metabolism in
Enterocytes are responsible for the absorption of dietary lipids, which involves TRL [TG (triacylglycerol)-rich lipoprotein] assembly and secretion. In the present study, we analysed the effect on TRL secretion of Caco-2 enterocyte adaptation to a differential glucose supply. We showed that TG
The mitochondrial beta-oxidation system is one of the central metabolic pathways of energy metabolism in mammals. Enzyme defects in this pathway cause fatty acid oxidation disorders. To elucidate the role of 2,4-dienoyl-CoA reductase (DECR) as an auxiliary enzyme in the mitochondrial beta-oxidation
The aim of the present study was to evaluate the acute effect of ethanol on insulin sensitivity, and glucose, insulin, free fatty acid (FFA), and triacylglycerol responses in ten patients with non-insulin-dependent (type 2) diabetes. In the test study an oral dose of 0.66 g ethanol/kg followed by
Chlorogenic acid, a phenolic compound found ubiquitously in plants, is an in vitro antioxidant and metal chelator. Some derivatives of chlorogenic acid are hypoglycemic agents and may affect lipid metabolism. Concentrations of cholesterol and triacylglycerols are of interest due to their association
Rates of lipolysis and reesterification were determined under various conditions in adipocytes from epididymal fat pads of old, spontaneously obese rats and compared to cells from younger, leaner animals. No differences were observed in lipolytic responsiveness to several concentrations (2--50
1. This is the first description of the metabolic activity of a novel adenosine A1-receptor agonist, GR79236. GR79236 inhibited catecholamine-induced lipolysis in human, rat and dog isolated adipocytes. 2. Oral administration of GR79236 (0.1-10 mg/kg) to fed rats induced minimal changes in the
Barth syndrome (BTHS) is an X-linked genetic disease resulting in loss of cardiolipin (Ptd2Gro). Patients may be predisposed to hypoglycemia and exhibit increases in whole-body glucose disposal rates and a higher fat mass percentage. We examined the reasons for this in BTHS lymphoblasts. BTHS
Calreticulin is an endoplasmic reticulum resident Ca(2+)-binding chaperone. The importance of the protein is illustrated by embryonic lethality because of impaired cardiac development in calreticulin-deficient mice. The molecular details underlying this phenotype are not understood. In this study,
The effects of the hypoglycaemia sulphonylurea glibenclamide (HB419) and the non-metabolizable leucine analogue beta-2-aminobicyclo(2.2.1)heptane-2-carboxylic acid (BCH) on insulin release and endogenous substrate metabolism were studied in isolated rat islets. Pre-labelling of the endogenous islet
OBJECTIVE
CD36 deficiency is characterized by limited cellular long chain fatty acid uptake in the skeletal and cardiac muscles and often causes energy crisis in these muscles. However, suitable treatment for CD36 deficiency remains to be established. The aim of this study was to evaluate the
