| Research Abstract |
The objective of this study was to examine whether the over-expression of miR-146 inhibits osteoclastogenesis, and prevent joint destruction by administration of miR-146a in collagen induced arthritis(CIA) mice. After the onset of distinct arthritis in CIA mice, ds miR-146a or scrambled siRNA was administered twice by intravenous injection. Radiographic and histological examinations were evaluated at 4 weeks. Administration of miR-146a could prevent joint destruction in CIA mice through the suppression of osteoclastogenesis and inflammation.
