Sex Hormone binding globulin (SHBG) is a plasma steroid binding protein that is the major determinant androgen and estrogen access to target tissues. Several ligands of SHBG have been predicted by computational methods or discovered through basic research, they include pharmaceutical, natural plant extracts and anthropogenic endocrine disrupting compounds. In this study we characterized 3,4-Divanillyltetrahydrofuran (DVT), a non-steroidal ligand of SHBG, and Danazol, a synthet...

Introduction: Aging is associated with a decrease in muscle and bone mass, and a gain in fat mass. Similar changes are more pronounced in hypercortisolism. We previously demonstrated that high 8 PM salivary cortisol is independently associated with increased prevalence of radiologic vertebral fractures. We wanted to determine whether salivary cortisol circadian rhythm played also a role on body composition.Material and Methods: Cross-sectional study incl...

Corticosteroid-binding globulin (CBG) transports glucocorticoids in blood and is a serine protease inhibitor family member. Plasma CBG has a reactive center loop (RCL) structure that when cleaved by specific proteases, including neutrophil elastase, results in a loss of high affinity steroid-binding activity. Measurements of CBG levels are typically based on functional assays of its steroid-binding capacity or immunoassays, including enzyme-linked immunosorbant assays (ELISAs)...
