1 The 5-HT(1A) agonist 8-hydroxy-2 (di-n-propylamino) tetralin (8-OH-DPAT) causes inhibition of caspase-3 and apoptosis via the extracellular signal-regulated kinases (ERK1/2) in hippocampal HN2-5 cells. 8-Hydroxy-2-(di-n-propylamino)tetralin 5-hydroxytryptamine receptor 1A Homo sapiens
2 The 5-HT(1A) agonist 8-hydroxy-2 (di-n-propylamino) tetralin (8-OH-DPAT) causes inhibition of caspase-3 and apoptosis via the extracellular signal-regulated kinases (ERK1/2) in hippocampal HN2-5 cells. 8-Hydroxy-2-(di-n-propylamino)tetralin 5-hydroxytryptamine receptor 1A Homo sapiens
3 Two 5-HT(1A) agonists, Repinotan hydrochloride (BAY x 3702) and 8-OH-DPAT, block caspase-3 activation and apoptosis caused by anoxia/reoxygenation and H(2)O(2) treatment. 8-Hydroxy-2-(di-n-propylamino)tetralin 5-hydroxytryptamine receptor 1A Homo sapiens
4 Finally, transient expression of kinase-negative PKCalpha eliminated the 8-OH-DPAT-evoked block on the H(2)O(2)-triggered caspase-3 stimulation, establishing PKCalpha as a link between ERK and caspase-3 (5-HT(1A)-R-->PLC-->ERK1/2-->PKCalpha-->caspase-3). 8-Hydroxy-2-(di-n-propylamino)tetralin 5-hydroxytryptamine receptor 1A Homo sapiens
