Mitf has been implicated to be a key regulator of the later steps of osteoclastogenesis, but the role of Mitf is not fully elucidated; although nine distinct Mitf isoforms, which contain an isoform-specific first exon and are identical exons 2 to 9, have been identified at the RNA level, it is unclear whether any isoforms are unique to the osteoclast lineage cells. Treatment of RAW264 macrophage-like cells with sRANKL (100 ng/ml) for 72 h resulted in the increase in the number of Trap-positive multinucleated cells. The present study examined expression of Mitf isoforms in sRANKL-induced osteoclast-like cells. The s-RANKL treatment induced robust expression of Mitf-E gene. In addition, Tfe3, another member of the bHLH-ZIP family, was also significantly expressed throughout the differentiation of RAW264 cells. E isoform of Mitfs may be involved in the regulation of the late process in osteoclast development. Previous studies have revealed that tartrate-resistant acid phosphatase (Trap) is a transcriptional target of Mitf in osteoclasts. Thus, we also examined factors affecting Trap gene transcription in HepG2 cells that are responsive to Mitf overexpression. Transcriptional activation assays using luciferase-based reporter gene containing Trap promoter (-2049 - +1) revealed that overexpression of Mitf-J/-D/-E but not Mitf-A slightly increased luciferase expression. The overexpression of c-Jun but not c-Fos and JunB increased expression of Trap reporter gene, and synergistic effects of c-Jun and Mitfs (-A and -J/-D/-E) on Trap gene transcription were detected. In contrast, no synergism was observed between Mitf and the other AP-1 component (c-Fos and JunB). Distinct expression of Mitf isoforms and functional interaction between Mitf and the other transcription factor such as c-Jun during the terminal differentiation of osteoclasts suggests discrete

Mitf has been implicated to be a key regulator of the later steps of osteoclastogenesis, but the role of Mitf is not fully elucidated; although nine distinct Mitf isoforms, which contain an isoform-specific first exon and are identical exons 2 to 9, have been identified at the RNA level, it is unclear whether any isoforms are unique to the osteoclast lineage cells.
