Outline of Final Research Achievements |
Treatment with RANKL induces osteoclastogenesis in murine and canine bone marrow cells as well as murine RAW264.7 cells. Analyses of Mitf isoform expression indicated that Mitf-E gene was induced within 24 hours after RANKL treatment in all examined cells. Knockdown of Mitf-E by its siRNA transfection inhibited RANKL-induced osteoclastogenesis. In mouse cells, co-treatment with TGF-β enhanced RANKL-induced osteoclastogenesis, whereas TGF-β inhibited canine osteoclastogenesis induced by RANKL.
