1 We also found that levels of endogenous p-Thr32-FOXO3a and p-Ser253-FOXO3a were lower in AZD6244-sensitive cells than in AZD6244-resistant cells. AZD 6244 forkhead box O3 Homo sapiens
2 We also found that levels of endogenous p-Thr32-FOXO3a and p-Ser253-FOXO3a were lower in AZD6244-sensitive cells than in AZD6244-resistant cells. AZD 6244 forkhead box O3 Homo sapiens
3 We also found that levels of endogenous p-Thr32-FOXO3a and p-Ser253-FOXO3a were lower in AZD6244-sensitive cells than in AZD6244-resistant cells. AZD 6244 forkhead box O3 Homo sapiens
4 We also found that levels of endogenous p-Thr32-FOXO3a and p-Ser253-FOXO3a were lower in AZD6244-sensitive cells than in AZD6244-resistant cells. AZD 6244 forkhead box O3 Homo sapiens
5 In the sensitive cells, AZD6244 induced FOXO3a nuclear translocation required for Bim activation. AZD 6244 forkhead box O3 Homo sapiens
6 Moreover, the silencing of FOXO3a by siRNA abrogated AZD6244-induced cell apoptosis. AZD 6244 forkhead box O3 Homo sapiens
7 These results show that Bim plays an important role in AZD6244-induced apoptosis in lung cancer cells and that the PI3K/AKT/FOXO3a pathway is involved in Bim regulation and susceptibility of lung cancer cells to AZD6244. AZD 6244 forkhead box O3 Homo sapiens
