This study generated RANK-knockout mice to define the precise role of the RANK receptor in osteoclast biology. Using genetic deletion, bone marrow transplantation, and retroviral gene rescue, the authors ask whether RANK is the sole receptor mediating osteoclast formation and whether all bone-resorbing hormones and cytokines act through it.
Understanding RANK's central role explains how conditions affecting osteoclast function lead to bone disease and why RANKL inhibitors like denosumab are effective in treating osteoporosis and bone metastases.
