OSU53 Rescues Human OB-6 Osteoblastic Cells from Dexamethasone through Activating AMPK Signaling

Excessive dexamethasone (Dex) application causes osteoblast cell death, which could lead to osteoporosis or osteonecrosis. AMP-activated protein kinase (AMPK) activation is shown to protect osteoblasts/osteoblastic cells from Dex. In this report, we tested the potential effect of OSU53, a novel AMPK activator, in Dex-treated osteoblastic cells. We show that… CONTINUE READING
