Special Issue Information

Dear Colleagues,

Bone regulation offers striking new opportunities for its better understanding. Integration between molecular and endocrine mechanisms reveals unexpected relationships. Discovery of new agents involved in bone development has opened wide perspectives for the physiology and treatment of bone diseases and osteoporosis. Systemic regulation of bone mass by hormones such as growth hormone and IGF1, sex steroids, but also neuroendocrine hormones like leptin, ghrelin, oxytocin or other putative regulators during development and beyond is prominent. New actors such as FGF23 have appeared. The control of bone mass under recruitment and differentiation of osteoblasts precursors, as well as the role of osteocyte under mechanic stimulation, remain a still largely unexplored area. Local paracrine regulators, namely linked to the sclerostin pathway, seem also prominent. The goal is to provide an integrative vision of the main systemic and local regulators of bone mass, with special regard to new therapeutic options.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract: The regulation of bone remodeling is strongly dependent on Wnt signaling, where activation of the Wnt pathway leads to increased bone mass and inactivation leads to bone loss. Sclerostin, a 22-kDa glycoprotein encoded by the SOST gene, is mainly produced by osteocytes and is a critical regulator of bone formation through its inhibitory effect on Wnt signaling. Besides inhibiting bone formation and osteoblastogenesis, it has also been demonstrated that sclerostin stimulates osteoclastogenesis and bone resorption. The osteocyte network is a vast and highly complex communication network and orchestrate the function of osteoblasts and osteoclasts in response to both mechanical and hormonal cues. The expression of sclerostin is limited to mature osteocytes. Downregulation of the SOST gene and local Wnt signaling are required for the osteogenic response to mechanical loading. Sclerostin is also present in the circulation and evidence suggests that sclerostin might also exert an endocrine function. Different immunoassays for the assessment of serum sclerostin are commercially available; however, differences due to immunoassay variability have been reported. Second generation assays for sclerostin, designated as bioactive sclerostin, have recently been developed, which might overcome some of the reported methodological obstacles. Current knowledge of sclerostin, with a focus on osteogenesis and methodological aspects of modern immunoassays, is summarized in this review.

Title: AROMATASE MUTATION IN MEN: A CASE REPORT AND REVIEW OF THE LITERATURE

Abstract: (1) Background: The clinical relevance of aromatase to a functioning male metabolism has become evident since 1991, when cases of patients with estrogen deficiency caused by aromatase mutation were first described. Only few cases are known so far, which will now be presented in a case report and review of the literature. (2) Methods: All available publications since the first description in 1991 dealing with loss-of-function aromatase mutation in men were summarized and our care report added. (3) Results: The mutations that cause the aromatase protein to lose function lead to a rather heterogeneous clinical picture. It is, however, clear that estrogens play a central role in male patients, especially in bone metabolism. Most frequently, tall stature, unclosed epiphyseal joints, and osteoporosis are detected in affected individuals as a consequence of the change in hormonal status. (4) Conclusions: Despite aromatase deficiency being a rare disease, the study of the effects of estrogen on male bone development provides important insights for endocrine bone regulation. It has been demonstrated that androgens alone are not sufficient for adequate skeletal development in males. This work highlights the important role of estrogens in individual health and disease in men.
