1 JWA is required for arsenic trioxide induced apoptosis in HeLa and MCF-7 cells via reactive oxygen species and mitochondria linked signal pathway. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
2 JWA, a novel retinoic acid-inducible gene, is known to be involved in apoptosis induced by various agents, for example, 12-O-tetradecanoylphorbol 13-acetate, N-4-hydroxy-phenyl-retinamide and arsenic trioxide. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
3 Herein, our studies demonstrated that treatment of arsenic trioxide produced apoptosis in HeLa and MCF-7 cells in a dose-dependent manner and paralleled with increased JWA expression. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
4 JWA expression was dependent upon generation of intracellular reactive oxygen species induced by arsenic trioxide. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
5 Knockdown of JWA attenuated arsenic trioxide induced apoptosis, and was accompanied by significantly reduced activity of caspase-9, enhanced Bad phosphorylation and inhibited MEK1/2, ERK1/2 and JNK phosphorylations. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
6 Arsenic trioxide induced loss of mitochondrial transmembrane potential was JWA-dependent. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
7 These findings suggest that JWA may serve as a pro-apoptotic molecule to mediate arsenic trioxide triggered apoptosis via a reactive oxygen species and mitochondria-associated signal pathway. Arsenic Trioxide ADP ribosylation factor like GTPase 6 interacting protein 5 Homo sapiens
