MiR-21 overexpression improves osteoporosis by targeting RECK.
Abstract Osteoporosis is a kind of metabolic bone disorder. MicroRNA-21 (miR-21) has been proven to play an important role in bone formation, whereas its role in osteoporosis is unclear. In the present study, miR-21 expression was inhibited by TNF-α in mesenchymal stem cells (MSCs). TNF-α induced cell apoptosis, and inhibited cell proliferation and differentiation of MSCs. Whereas the effect was reversed by miR-21 mimics. Expression of reversion-inducing cysteine-rich protein with Kazal motifs (RECK) which is a predicted target of miR-21 was inhibited by miR-21 mimics. A luciferase reporter gene assay showed th...
