Two mRNA species of the Huntington disease (HD) gene that share identical protein coding sequences but differ in their 3' untranslated region have been identified in human. Although a similar situation has been suggested to occur in mouse, only one cDNA has been isolated to date. We report the isolation of a novel partial cDNA of the mouse HD gene that is(More)
miR-33 and miR-122 are major regulators of lipid metabolism in the liver, and their deregulation has been linked to the development of metabolic diseases such as obesity and metabolic syndrome. However, the biological importance of these miRNAs has been defined using genetic models. The aim of this study was to evaluate whether the levels of miR-122 and(More)
Modulation of miR-33 and miR-122 has been proposed to be a promising strategy to treat dyslipidemia and insulin resistance associated with obesity and metabolic syndrome. Interestingly, specific polyphenols reduce the levels of these mi(cro)RNAs. The aim of this study was to elucidate the effect of polyphenols of different chemical structure on miR-33a and(More)
Met, the tyrosine kinase receptor for hepatocyte growth factor (HGF), mainly activates prosurvival pathways, including protection from apoptosis. In this work, we investigated the cardioprotective mechanisms of Met activation by agonist monoclonal antibodies (mAbs). Cobalt chloride (CoCl2), a chemical mimetic of hypoxia, was used to induce cardiac damage in(More)
Metabolism follows circadian rhythms, which are driven by peripheral clocks. Clock genes in the liver are entrained by daytime meals and food components. Proanthocyanidins (PAs), the most abundant flavonoids in the human diet, modulate lipid and glucose metabolism. The aim of this study was to determine whether PAs could adjust the clock system in the(More)
We report the differential alterations produced by chronic ethanol treatment on the modulation, by the barbiturate thiopental and the steroid 5 beta-pregnan-3 alpha-ol-20-one, of the binding of [3H]muscimol to membrane preparations from rat brain cortex. We found a clear barbiturate- and steroid-promoted enhancement of muscimol-binding to membranes in both(More)
