title: Effect of 5-hydroxytryptamine 1A receptor agonist BAY X 3702 on BCL-2 and BAX proteins level in the ipsilateral cerebral cortex of rats after transient focal ischaemia.
abstract: The proto-oncogene B-cell lymphoma protein 2 (BCL-2) and its homologues are important modulators of cellular survival after transient brain ischaemia. In the present study we used western blotting to elucidate if the stimulation of 5-hydroxytryptamine 1A type receptors with their agonist BAY X 3702 results in regulation of BCL-2 family proteins. Treatment with BAY X 3702 resulted in elevated BCL-2 protein level in the ipsilateral cerebral cortex of animals as early as at 6 and 12 h of reperfusion, this effect becoming more pronounced at 24 h. BAY X 3702 administration caused no change in BCL-2-associated protein X content during reperfusion. The effect of BAY X 3702 on the level of death-inhibiting protein BCL-2 in the brain during ischaemia/reperfusion could contribute to the neuroprotective potency of the drug.
