Sulforaphene attenuates multinucleation of pre-osteoclasts by suppressing expression of cell-cell fusion-associated genes DC-STAMP, OC-STAMP, and Atp6v0d2

Abstract

We assessed the effect of sulforaphene (SFE) on osteoclast differentiation. SFE significantly decreased the number of RANKL-induced tartrate-resistant acid phosphatase-positive cells and suppressed pre-osteoclast multinucleation. Furthermore, SFE downregulated mRNA expression of DC-STAMP, OC-STAMP, and Atp6v0d2, which encode cell-cell fusion molecules. Our data suggest that SFE attenuates pre-osteoclast multinucleation via suppression of cell-cell fusion.

Keywords: dendritic cell-specific transmembrane protein (DC-STAMP); isothiocyanate; osteoclast cell fusion; sulforaphene; v-ATPase V0 subunit d2(Atp6v0d2).
