Growth factors such as insulin-like growth factor type I (IGF-I), epidermal growth factor (EGF), vascular-endothelial growth factor (VEGF) and transforming growth factor beta (TGF-beta) are present during the development of the CNS. When they reappear in the mature brain they are overexpressed in neoplastic glia, participating in the development of the most(More)
It is now well established that in epileptic patients, hypometabolic foci appear during interictal periods. The meaning and the mechanism of such an hypometabolism are as yet unclear. The aim of the present investigation was to look for a putative relationship between glucose metabolism in the brain and the genesis of seizures in mice using administration(More)
A novel pyridine derivative, 8-{4-[(6-methoxy-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine-3-ylmethyl)-amino]-butyl}-8-aza-spiro[4.5]decane-7,9-dione hydrochloride, termed JB-788, was designed to selectively target 5-HT(1A) receptors. In the present study, the pharmacological profile of JB-788 was characterized in vitro using radioligands binding tests and in(More)
Methionine sulfoximine is a xenobiotic amino acid derived from methionine. One of its major properties is to display a glycogenic activity in the brain. After studying this property, we investigate here a possible action of this xenobiotic on the expression of genes related to carbohydrate anabolism in the brain. Glycogen was studied by the means of(More)
Few studies have addressed the ultrastructure and morphology of neurons in primary pure culture. We therefore use immunohistochemistry and electron microscopy to investigate the ultrastructure of cultured neurons during extended incubation in vitro. Rat cerebral cortex neurons were cultured in Neurobasal™ medium. Adherent cells developed as networks of(More)
The mouse fructose-1,6-bisphosphatase (FBPase) cDNA was previously cloned from testicular teratocarcinoma cultured cells (F9 cells). Using this published nucleotide sequence four primer sets were defined and used to amplify FBPase transcript from cerebral cortex, heart, kidney, liver and testis of male C57B1/6 mice. Only one primer set was efficient in all(More)
Abnormalities of carbohydrate metabolism and monoamine neurotransmitters have been widely implicated in the pathoetiology of human epilepsy, and glucose hypometabolism and/or tryptophan utilization can be used to localize epileptic foci in the human brain. To investigate the neurochemical changes that underlie seizure susceptibility we studied four strains(More)
