Bone loss occurs following chronic ethanol (EtOH) consumption in males and cycling females in part as a result of increased bone resorption. We have demonstrated in vivo that estradiol treatment can reverse this effect. Using osteoclast precursors from bone marrow and osteoblast/preosteoclast coculture, we found that EtOH-induced receptor activator of nuclear factor-κB ligand (RANKL) expression in osteoblasts was able to promote osteoclastogenesis. These effects were blocked by pretreatment of… CONTINUE READING
