چکیده انگلیسی
Wnt10a is a member of the WNT family. Although deficiency of this gene causes symptoms related to teeth, hair, nails, and skin, we recently demonstrated a new phenotype of Wnt10a knockout (KO) mice involving bone and fat. The in vivo effect of the Wnt10a gene on bone and fat is unclear, and the relationship between bone/fat and muscle in Wnt10a signaling is also interesting. We aimed to evaluate the tissue changes in Wnt10a KO mice compared to wild-type mice and show the findings as a starting point to unravel the underlying mechanisms of in vivo interactions involving Wnt10a in bone, fat and muscle. Trabecular bone loss in the lower limbs of Wnt10a mice and decreased bone mineralization were observed. The adipose tissue in bone marrow was also decreased, and adipocyte differentiation was reduced. The body fat mass in Wnt10a KO mice was decreased, and white adipocytes in subcutaneous fat were converted to beige adipocytes. The muscle weight of the lower limbs was not decreased despite trabecular bone loss, but Gdf8/myostatin expression was reduced in the subcutaneous fat and gastrocnemius muscles of Wnt10a KO mice. Thus, in vivo deletion of Wnt10a inhibited osteogenic activity, promoted beige adipogenesis of white adipocytes and maintained muscle mass. These results suggest that regulation of Gdf8 by Wnt10a may help maintain the muscle mass of Wnt10a KO mice. This study was the first to histologically evaluate the bone, fat and muscle phenotypes of Wnt10a KO mice. The results of this study, which were obtained by investigating the three tissues together, could influence the understanding of in vivo interactions involving the Wnt10a gene.
