Background: Cell-mediated initiation of enchondral ossification is essential for growth plate maturation. The matrix mineralization inhibitors matrix Gla protein (MGP) and osteocalcin (OC) represent key regulators of matrix mineralization and are highly expressed in growth plate chondrocytes. Pharmacological or nutritional phylloquinone (K1) depletion is known to affect skeletal mineralization by reduced gamma-carboxilisation of MGP and OC. Constituents of mineral matrix such ...

Background: The acid-labile subunit (ALS) is the crucial third player in the tertiary complex for its function of prolonging the half-life of the IGF1-IGFBP3 binary complexes. IGF1 and IGFBP3 are routinely determined during the diagnostic work-up for growth hormone deficiency (GHD). The aim of the study is to evaluate the relevance of serum ALS as an additional biomarker, alone or in combination with IGF1 and IGFBP3, in the diagnosis of GHD.<p class="abste...
