Epilepsy affects around 50 million people worldwide, and in about 65 % of patients, the etiology of disease is unknown. MicroRNAs are small non-coding RNAs that have been suggested to play a role in the pathophysiology of epilepsy. Here, we compared microRNA expression patterns in the hippocampus using two chronic models of epilepsy characterised by(More)
The glutathione S-transferases (GSTs) constitute a family of cytosolic isoenzymes and a structurally unrelated microsomal enzyme that is involved in the detoxication of electrophilic xenobiotics. These enzymes also participate in the intracellular binding and transport of a broad range of lipophilic compounds including bilirubin, and hormones such as the(More)
Brown adipocytes are a primary site of energy expenditure and reside not only in classical brown adipose tissue but can also be found in white adipose tissue. Here we show that microRNA 155 is enriched in brown adipose tissue and is highly expressed in proliferating brown preadipocytes but declines after induction of differentiation. Interestingly, microRNA(More)
We determined the calmodulin concentration and Ca2+-ATPase activity in subcellular fractions recovered from samples of vastus lateralis muscle obtained from 18 patients with Duchenne muscular dystrophy, 10 patients with other primary myopathies, 5 with spinal muscular atrophy, and 16 age-matched controls. Calmodulin levels were increased in the cytosol,(More)
PURPOSE The glutathione S-transferases (GSTs) constitute a family of cytosolic isoenzymes that are involved in the detoxication of electrophilic xenobiotics. The purpose of this investigation was to determine the concentration and cellular distribution of the various classes of cytosolic GSTs in the retina of control and triethyl lead-treated rats and(More)
The posttranslational modification of calmodulin has been studied in six brain regions and the anterior pituitary. Carboxylmethylation, calmodulin converting enzyme, and calmodulin (lysine) N-methyltransferase activities were determined. Incubation of calmodulin with cytosolic extracts of these tissues in the presence of the methyl donor(More)
This study is concerned with cortico-thalamic neural mechanisms underlying attentional phenomena. Previous results from this laboratory demonstrated that the visual sector of the GABAergic thalamic reticular nucleus is selectively c-fos activated in rats that are naturally paying attention to features of a novel-complex environment, and that this activation(More)
Pregnant albino rats were placed on a complete liquid diet (Ensure) containing either 9% ethanol or an isocaloric amount of sucrose between the third and twentieth day of gestation. The pups born to these rats were sacrificed either day 11 or day 14 postnatum and morphometrical, histological and biochemical analyses were done on their cerebellums and(More)
The glutathione S-transferases (GSTs) are a family of isoenzymes involved in the detoxication of a variety of electrophilic xenobiotics. The present investigation demonstrates that GST activity and the concentration of cytosolic GSTs in cerebellar cortex of Gunn rats were increased in hyperbilirubinaemic animals compared with non-jaundiced controls.(More)
