1 METHODS AND MATERIALS: Lung, prostate, and breast cancer cells were treated with IR (2-8 Gy) after incubation with either ATM or AMPK inhibitors or the AMPK activator metformin. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
2 Compound C caused resistance to IR, increasing the surviving fraction after 2 Gy, but the anti-diabetic drug metformin enhanced IR activation of AMPK and lowered the surviving fraction after 2 Gy further. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
3 AMPK appears to (1) participate in an ATM-AMPK-p21(waf/cip) pathway, (2) be involved in regulation of the IR-induced G2/M checkpoint, and (3) may be targeted by metformin to enhance IR responses. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
