Age-related bone loss is a major cause of osteoporosis and osteoporotic fractures in the elderly. However, the underlying molecular mechanism of age-related bone loss is still poorly understood. The aim of this study was to clarify whether autophagy in osteocytes was involved in age-related bone loss. Male Sprague-Dawley (SD) rats in 3, 9, and 24 month old were used to mimic the age-related bone loss in men. Micro-CT evaluation, histomorphometric analysis, and measurement of bone turnover rate verified age-related bone loss in the male SD rats. Immunofluorescent histochemistry, RT-PCR, and Western blot assessment demonstrated that the expression of LC3-II, LC3-II/I, Beclin-1, and Ulk-1 in the osteocytes decreased with age, while SQSTM1/p62 and apoptosis in the osteocytes increased. A significant correlation between the markers of osteocyte autophagy and bone mineral density in the proximal tibia was revealed. However, osteocyte autophagy was not correlated with osteocyte apoptosis in the process of aging. These results suggested that osteocyte autophagy was possibly involved in the age-related bone loss. Decreased activity of osteocyte autophagy independent of apoptosis might contribute to the age-related bone loss in senile osteoporosis.
