Teriparatide facilitates osteogenic differentiation of bone mesenchymal stem cells to alleviate idiopathic osteoporosis via the circFNDC3B-miR-125a-5p-GLS axis.

ABSTRACT: Osteoporosis (OP), a systemic bone disease, is characterized by degeneration of bone microstructure and susceptibility to fracture. Teriparatide (TPD) is an active fragment of human endogenous parathyroid hormone which has been revealed to promote osteogenesis of mesenchymal stem cells (hMSCs) to alleviate osteoporosis. Currently, the underlying cellular and molecular mechanisms of TPD in treating OP were not fully understood. This study aimed to investigate the roles of non-coding RNA-regulated osteogenic differentiation of hMSCs under TPD treatments. Circular RNA FNDC3B was significantly downregulated, and miRNA-125a-5p was upregulated in primary hMSCs of osteoporosis patients. Moreover, during osteogenesis, expression of circFNDC3B and glutamine metabolism were gradually elevated and mi
