Etoposide 77-86 AKT serine/threonine kinase 1 Homo sapiens 99-102 15674326-6 2005 The G2/M arrest induced by etoposide was also enhanced or inhibited by expression of a constitutively activated or dominant-negative Akt mutant, respectively. Etoposide 27-36 AKT serine/threonine kinase 1 Homo sapiens 133-136 15674326-7 2005 Furthermore, SB216763 or LiCl, a specific inhibitor for the GSK3 kinase inhibited by Akt, enhanced the Chk1 phosphorylation and G2/M arrest by etoposide. Etoposide 143-152 AKT serine/threonine kinase 1 Homo sapiens 85-88 15674326-8 2005 These results indicate that hematopoietic cytokines protect etoposide-treated cells from DNA damage-induced apoptosis by promoting, through the PI3K/Akt/GSK3 signaling pathway, G2/M checkpoint that is dependent on Chk1-mediated inhibition of Cdc2. Etoposide 60-69 AKT serine/threonine kinase 1 Homo sapiens 149-152
