1 To define the mechanisms of anticancer effects of metformin, we examined its influence on AMPK activation and NF-kappaB pathway. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
2 Activation of AMPK by metformin not only inhibited HCC cells growth in vitro and in vivo, but also augmented cisplatin-induced growth inhibition in HCC cells. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
3 Knockdown of AMPKalpha expression can greatly decrease the inhibitory effect of metformin, indicating that AMPK activation is required for the anticancer action of metformin. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
4 Knockdown of AMPKalpha expression can greatly decrease the inhibitory effect of metformin, indicating that AMPK activation is required for the anticancer action of metformin. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
5 Mechanistically, metformin/AMPK activation inhibited NF-kappaB signaling through upregulation of IkappaBalpha. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
