Complex changes in gene expression are associated with insulin resistance and non-alcoholic fatty liver disease (NAFLD) promoted by feeding a high-fat diet (HFD). We used functional genomic technologies to document molecular mechanisms associated with diet-induced NAFLD. Male 129S6 mice were fed a diet containing 40% fat (high-fat diet, HFD) for 15 weeks.(More)
Dyslipidaemia is a main component of the insulin resistance syndrome. The inbred Goto–Kakizaki (GK) rat is a model of spontaneous type 2 diabetes and insulin resistance, which has been used to identify diabetes-related susceptibility loci in genetic crosses. The objective of our study was to test the genetic control of lipid metabolism in the GK rat and(More)
PURPOSE Generalized nonconvulsive absence seizures are characterized by the occurrence of synchronous and bilateral spike-and-wave discharges (SWDs) on electroencephalographic recordings, concomitant with behavioral arrest. The GAERS (genetic absence rats from Strasbourg) strain, a well-characterized inbred model for idiopathic generalized epilepsy,(More)
Multiple sclerosis (MS) is a common inflammatory disease of the central nervous system unsurpassed for its variability in disease outcome. Apolipoprotein E (APOE) is involved in neuronal remodelling and several studies have attempted to examine the effect of APOE on MS disease severity, but its function in modifying the course of MS is controversial. It has(More)
Over the past decades, genetic studies in rodent models of human multifactorial disorders have led to the detection of numerous chromosomal regions associated with disease phenotypes. Owing to the complex control of these phenotypes and the size of the disease loci, identifying the underlying genes requires further analyses in new original models, including(More)
Genetic investigations in the spontaneously diabetic (Type 2) Goto Kakizaki (GK) rat have identified quantitative trait loci (QTL) for diabetes-related phenotypes. The aims of this study were to refine the chromosomal mapping of a QTL (Nidd/gk5) identified in chromosome 8 of the GK rat and to define a pathophysiological profile of GK gene variants(More)
PURPOSE The WAG/Rij rat is among the most appropriate models for the study of spontaneous childhood absence epilepsy, without complex neurologic disorders that are associated with some mouse models for absence epilepsy. Previous studies have allowed the identification of distinct types of spike-wave discharges (SWDs) characterizing seizures in this strain.(More)
Extracellular matrix molecules such as elastin and collagens provide mechanical support to the vessel wall. In addition to its structural role, elastin is a regulator that maintains homeostasis through biologic signaling. Genetically determined minor modifications in elastin and collagen in the aorta could influence the onset and evolution of arterial(More)
In a previous study, by using a candidate gene approach, we detected in both Milan hypertensive rats and humans a polymorphism in the alpha-adducin gene (ADD1) that was associated with blood pressure and renal sodium handling. In the present study, a genomewide search with 264 informative markers was undertaken in 251 (Milan hypertensive strain x Milan(More)
Unrestrained pregnant rats were infused with glucose during the last week of pregnancy to produce slight or high gestational hyperglycaemia. Control rats were infused with distilled water. Insulin secretion of the fetuses at term was studied in vitro using a perifusion system. Compared with controls, perifused pancreases of slightly hyperglycaemic fetuses(More)
