Serum sclerostin does not reflect its expression in bone, but is related to bone mineral density

Bravenboer Nathalie , Visser Ruben , den Heijer Martin , Heijboer Annemieke

Sclerostin is a major negative regulator of osteoblastic activity. Serum sclerostin has a weak positive association with BMD but contradictory results have been described concerning associations with fractures. These contradictions could be explained by the fact that serum sclerostin does not reflect its action in bone. In this study we question whether serum sclerostin is associated with its expression in bone. In addition we aimed to detect associations between sclerostin in...

Effect of postponing puberty and cross-sex hormone therapy on bone turnover markers and BMAD in transgender adolescents

Vlot Mariska , Klink Daniel , den Heijer Martin , Blankenstein Marinus , Rotteveel Joost , Heijboer Annemieke

Background: Puberty is highly important for the accumulation of bone mass. Bone turnover and bone mineral density can be affected in transgender adolescents when puberty is postponed by gonadotropin-releasing hormone analogues (GnRHa), followed by treatment with cross-sex hormone therapy (CSHT).Objective: To investigate the effect of GnRHa and CSHT on bone turnover markers (BTMs) and bone mineral apparent density (BMAD) in transgender adolescents.<p ...

Dynamic changes in bone marrow adiposity during the menstrual cycle

Background: Bone marrow (BM) adiposity is inversely related to bone mineral density and increases with ageing and menopause. We previously observed that the variation in BM fat fraction was more pronounced in premenopausal women compared to men and postmenopausal women. We hypothesized that the variation in BM fat fraction in premenopausal women is associated with hormonal variations during the menstrual cycle.Objective: To investigate the dynamic change...
