1 Caspase activation is accelerated by the inhibition of arsenite-induced, membrane rafts-dependent Akt activation. arsenite AKT serine/threonine kinase 1 Homo sapiens
2 Arsenite-induced Akt phosphorylation also was inhibited by sequestrating membrane cholesterol with beta cyclodextrin. arsenite AKT serine/threonine kinase 1 Homo sapiens
3 Reducing reagents/reactive oxygen species (ROS) scavengers reduced arsenite-induced Akt phosphorylation and beta cyclodextrin reduced arsenite-mediated ROS production, suggesting that arsenite-induced G-protein/Akt/GSK3beta pathway is membrane raft dependent and redox linked. arsenite AKT serine/threonine kinase 1 Homo sapiens
4 Reducing reagents/reactive oxygen species (ROS) scavengers reduced arsenite-induced Akt phosphorylation and beta cyclodextrin reduced arsenite-mediated ROS production, suggesting that arsenite-induced G-protein/Akt/GSK3beta pathway is membrane raft dependent and redox linked. arsenite AKT serine/threonine kinase 1 Homo sapiens
5 These results suggested that selective blockade of the arsenite-provoked PI-3 kinase/Akt pathway can promote the arsenite-triggered pathway for caspase activation, and this may open a new study area for wider applications of arsenic as a drug for treating various kinds of leukemia. arsenite AKT serine/threonine kinase 1 Homo sapiens
