| Summary: | Objective. To demonstrate the role of Wnt/β-catenin canonical pathway in postmenopausal osteoporosis by evaluating serum β-catenin levels in patients with postmenopausal osteoporosis and analyzing their possible relationship with serum OPG, RANKL, the ratio of RANKL/OPG, sclerostin, and bone turnover markers. Methods. 480 patients with postmenopausal osteoporosis and 170 healthy postmenopausal women were enrolled in the study. Serum β-catenin, OPG, RANKL, and sclerostin levels were measured by enzyme-linked immunosorbent assay. Bone status was assessed by measuring bone mineral density and bone turnover markers. Estradiol levels were also detected. Results. Serum β-catenin levels were lower in postmenopausal osteoporotic women compared to nonosteoporotic postmenopausal women (26.26±14.81 versus 39.33±5.47 pg/mL, P<0.001). Serum β-catenin was positively correlated with osteoprotegerin (r=0.232, P<0.001) and negatively correlated with the ratio of RANKL/OPG, body mass index, and sclerostin (r=-0.128, P=0.005; r=-0.117, P=0.010; r=-0.400, P<0.001, resp.) in patients with postmenopausal osteoporosis. Conclusion. The results indicate that lower serum β-catenin and concomitantly higher ratio of RANKL/OPG may be involved in the pathogenesis of postmenopausal osteoporosis. Functional communication between RANKL/RANK/OPG system and Wnt pathways plays an important role in postmenopausal osteoporosis. |
