1 Adenosine activates AMPK to phosphorylate Bcl-XL responsible for mitochondrial damage and DIABLO release in HuH-7 cells. Adenosine protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
2 The present study aimed at understanding AMPK signals for adenosine-induced HuH-7 cell apoptosis. Adenosine protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
3 Adenosine activated AMPK, to phosphorylate Bcl-X(L). Adenosine protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
4 Adenosine or AICAR disrupted mitochondrial membrane potentials, and the effect was inhibited by knocking-down AMPKalpha1 and/or AMPKalpha2, expressing dominant negative mutant AMPKalpha2 or mutant Bcl-X(L) lacking Ser/Thr phosphorylation sites. Adenosine protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
5 Adenosine or AICAR disrupted mitochondrial membrane potentials, and the effect was inhibited by knocking-down AMPKalpha1 and/or AMPKalpha2, expressing dominant negative mutant AMPKalpha2 or mutant Bcl-X(L) lacking Ser/Thr phosphorylation sites. Adenosine protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
6 CONCLUSION: Adenosine activates AMPK, to disrupt mitochondrial membrane potentials through Bcl-X(L) phosphorylation, allowing DIABLO release from the mitochondria, as a factor for caspase-3 activation to induce HuH-7 cell apoptosis. Adenosine protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
