BACKGROUND Urocortin is a novel cardioprotective agent that can protect cardiac myocytes from the damaging effects of ischemia/reperfusion both in culture and in the intact heart and is effective when given at reperfusion. METHODS AND RESULTS We have analyzed global changes in gene expression in cardiac myocytes after urocortin treatment using gene chip(More)
Clonidine (1.3 micrograms/kg) was administered to 62 control and 55 depressed patients free of psychoactive drugs for at least 7 days and fasted overnight. Growth hormone (GH), pulse, blood pressure and sedation were measured every 15 min for 1 h before and 2 h after clonidine infusion. GH response did not differ significantly between control and depressed(More)
A precise control of vesicular trafficking is crucial not only for osteoclastic bone resorption, but also for the crosstalk between osteoclasts and osteoblasts, which regulates bone homeostasis. In addition to the release of growth factors and modulators, such as glutamate, flux through the intracellular trafficking routes could also provide the osteoclast(More)
We previously reported that prenatal and suckling exposure to a maternal diet rich in animal fat leads to cardiovascular dysfunction in young adult rat offspring with subsequent development of dyslipidemia and hyperglycemia. We have further investigated glucose homeostasis in adult female offspring by euglycemic-hyperinsulinemic clamp and by dynamic(More)
Simulated ischaemia causes both necrotic and apoptotic death of primary cultures of neonatal rat cardiac myocytes. Simulated ischaemia is associated with increased expression of urocortin mRNA and with the release of urocortin peptide into the medium. Exogenous urocortin is more potent than corticotropin releasing hormone (CRH) in protecting cardiac(More)
Brain serotonin (5-HT) uptake sites were quantitated, by saturation binding of [3H]paroxetine, in 10 brain regions from 22 suicide victims and 20 control subjects. Suicide victims were restricted to those subjects in whom a firm retrospective diagnosis of depression was established and who had not recently been prescribed antidepressant drugs. The Kd and(More)
The urocortin (UCN) hormones UCN1 and UCN2 have been shown previously to confer significant protection against myocardial ischaemia/reperfusion (I/R) injury; however, the molecular mechanisms underlying their action are poorly understood. To further define the transcriptional effect of UCNs that underpins their cardioprotective activity, a microarray(More)
Using desmethylimipramine (DMI) defined and Na+ dependent [3H]imipramine binding, we have examined both 5-HT uptake sites and sites unrelated to 5-HT uptake, in frontal cortex, putamen and substantia nigra of suicides with a firm retrospective diagnosis of depression and matched controls. No differences were seen between antidepressant-free suicides and(More)
Saturation binding of [3H]paroxetine was performed in 10 brain regions from a group of suicide victims who had a firm, retrospective diagnosis of depression and who had been prescribed antidepressant drugs, as well as in a group of controls. The number of binding sites did not differ significantly between suicide victims and controls, apart from in putamen,(More)
