Bone homeostasis is shown by balancing the action of osteoblasts responsible for bone formation and osteoclasts responsible for bone resorption. However, factors such as menopause in women, hyperthyroidism, diabetes, stress, smoking and lack of exercise, physical aging and taking glucocorticoid drugs are known to cause osteoporosis, most of which inhibit osteoblast function or osteoclasts. Increased activity results in osteoporosis (1-3). That is, when osteoblast activity is decreased or osteoclast activity is increased, bone density may be reduced to cause osteoporosis. Therefore, inhibiting osteoclast function may treat or prevent osteoporosis.
Osteoclasts are differentiated by various differentiation-causing factors in macrophage progenitor cells (4-5). In particular, RANKL (receptor activator of nuclear factor kappa B ligand) secreted from osteoblasts binds to osteoclast precursor cells and RANK (receptor activator of nuclear factor kappa B) present on the surface of osteoclasts. Causes differentiation and activation (6). Differentiated osteoclasts were activated by NF-B, c-Fos, c-jun, AP-1, NFATc1, MAPK, ERK, JNK, p38 activation process, MITF, Src, Akt activation, etc. Induces bone resorption by promoting the expression of osteoclast-specific proteins such as cathepsin K and calcitonin receptor (7-9). When osteoclast differentiation and function are activated and absorption is increased, various bone diseases including osteoporosis can occur.
Cordycepin is known as the main component of Militaris cordyceps (or silkworm cordyceps), which contains about 2% of cordyceps militaris, and is mainly anticancer (10), immune enhancer (11), and antiallergic (12).
