1 Arsenite induces HIF-1alpha and VEGF through PI3K, Akt and reactive oxygen species in DU145 human prostate carcinoma cells. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
2 In this study, we investigated whether arsenite induces expression of hypoxia-inducible factor 1 (HIF-1). arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
3 In this study, we investigated whether arsenite induces expression of hypoxia-inducible factor 1 (HIF-1). arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
4 Here we demonstrate that arsenite induces the expression of HIF-1alpha but not HIF-1beta subunit in DU145 human prostate carcinoma cells. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
5 Arsenite also increases the expression of VEGF through the induction of HIF-1. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
6 We also found that arsenite activates PI3K and Akt that are required for arsenite-induced expression of HIF-1alpha and VEGF. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
7 We also found that arsenite activates PI3K and Akt that are required for arsenite-induced expression of HIF-1alpha and VEGF. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
8 The induction of HIF-1 and VEGF by arsenite can not be inhibited by MAP kinase inhibitors. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
9 These data indicate that the arsenite-induced activation of PI3K/Akt signaling and the expression of HIF-1 and VEGF through the generation of ROS could be an important mechanism in the arsenite-induced carcinogenesis. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
10 These data indicate that the arsenite-induced activation of PI3K/Akt signaling and the expression of HIF-1 and VEGF through the generation of ROS could be an important mechanism in the arsenite-induced carcinogenesis. arsenite hypoxia inducible factor 1 subunit alpha Homo sapiens
