AMPK is a key regulator of cellular and body energy homeostasis. We previously demonstrated that AMPK activation in osteoblasts increases bone formation in vitro while deletion of the AMPKα1 subunit leads to decreased bone mass in vivo. To determine whether bone turnover can be stimulated in the absence of AMPKα1 subunit, we subjected WT and AMPKα1−/− mice to catabolic (ovariectomy: OVX) and anabolic (intermittent PTH adminis...
