Here, we demonstrated that miR-146a knockout protects bone loss in mouse model of estrogen-deficient osteoporosis, and miR-146a inhibits OB and OC activities in vitro and in vivo.
Altogether, the results of the present study demonstrated that miR‑146a prevents osteoclast differentiation induced by LPS and RANKL co‑stimulation, suggesting that miR‑146a may be a promising therapeutic target for treatment of inflammation mediated bone loss.
In our study, we detect the levels of three micro-RNAs (miRNAs; miR-21, miR-133a and miR-146a) in the plasma of 120 Chinese postmenopausal women who were divided into three groups (normal, osteopenia and osteoporosis) according to the T-scores.
