Activated AMPK Protects Against Chronic Cerebral Ischemia in Bilateral Carotid Artery Stenosis Mice.

ABSTRACT: AMP-activated protein kinase (AMPK) is a regulator of cellular energy metabolism. Long-term use of metformin, an AMPK activator, was previously reported to be neuroprotective, as it promotes behavioral improvement and angiogenesis following an acute ischemic injury of the brain. However, only a few studies have demonstrated the role of AMPK in alleviating chronic cerebral ischemia (CCI) in mice models in the long-term (over 3 months). Therefore, we established a mouse model of CCI via bilateral carotid artery stenosis (BCAS) to explore the effect of AMPK on CCI. We used four groups of 3-month-old male C57BL/6 mice labeled as Sham, BCAS, BCAS + metformin treatment (BCAS + Met) and BCAS + AMPKα2 gene knockout (BCAS + KO). Three months after BCAS, we measured the AMPK protein expression, spat
