Functions of microRNAs in osteoporosis.

Osteoporosis (OP) is a kind of disease with a 25% incidence, characterized by the bone mass loss, bone microstructure damage, increased bone fragility, and easy fracture. miRNA plays an important regulatory role in the process of bone remodeling, especially in the regulation of differentiation and function of osteoblasts and osteoclasts, and the development and progression of OP and other bone diseases. In the future, it is expected to delay the bone loss and promote the bone remodeling via the overexpression or inhibition of specific miRNAs in specific tissues, thereby treating OP.
