Coenzyme Q10 (CoQ10) is a fatsoluble vitaminlike substance used for the treatment of a variety of disorders, including osteoporosis. The exact mechanism underlying CoQ10mediated protection against osteoporosis remains to be elucidated. The present study aimed to evaluate the effect
of CoQ10 on osteoblastic cell proliferation and differentiation, and therapeutic effects on a rat model of osteoporosis. Following treatment with different concentrations of CoQ10, cell proliferation and differentiation of rat bone marrow stromal cells (BMSCs), and expression of osteoblastogenic
markers, were measured. Rats with osteoporosis subjected to ovariectomy (OVX) were treated with different concentrations of CoQ10. Serum levels of estrogen and bone metabolism markers were measured. Micro computed tomography scans were used to analyze morphological changes in bones. In addition,
mRNA and protein levels of phosphatidylinositol 3,4,5trisphosphate 3phosphatase and dualspecificity protein phosphatase PTEN (PTEN)/phosphatidylinositol 4,5bisphosphate 3kinase (PI3K)/RACalpha serine/threonineprotein kinase(AKT), were determined. CoQ10 significantly increased the proliferation
and osteogenic differentiation of BMSCs in a dosedependent manner, with an increased expression of osteogenic markers. CoQ10 significantly decreased bone resorption but exhibited no effect on serum E2 levels in vivo. CoQ10 markedly enhanced bone formation. Furthermore, the abundance of
pPI3K and pAKT increased while PTEN levels decreased in a dosedependent manner following administration of CoQ10. CoQ10 stimulates the proliferation and differentiation of BMSCs and is effective for the treatment of OVXinduced osteoporosis in rats. The above effects of CoQ10 may be mediated
by activation of the PTEN/PI3K/AKT pathway.
