Wnt signaling is important for both skeletal development and bone disease, with Wnt inhibitory factors playing critical roles in bone metabolism. SHISA3 blocks the maturation and transportation of Frizzled receptors to the cell surface, thereby inhibiting the Wnt/β-catenin signaling pathway in lung cancer. However, the function of Shisa3 in bone biology remains uninvestigated. This study found that Shisa3 was strongly expressed in the calvarial bones of mice, especially in osteoblasts. In addition, adenovirus-mediated gene transfer of murine Shisa3 significantly inhibited Wnt3a-induced nuclear translocation ofβ-catenin and mRNA expression of the Wnt target geneAxin2. In bone phenotype assessments ofShisa3knockout (Shisa3KO) mice, micro-computed tomography, mRNA expressions of osteoblast markers, and skeletal preparations all displayed no significant differences compared withShisa3wild-type mice. mRNA expression analysis of canonical Wnt signaling target genes (Axin2,Lef1,Dkk1, andTnfrsf11b) in calvarial bones at P0.5 also revealed no significant findings. InAxin2Cre/ERT2knock-in mice, the number ofAxin2-expressing cells in the calvariae ofShisa3KO and control mice were comparable. Thus, there appears to be a redundancy in the function of Shisa3 in bone development, likely with other Shisa family members.
