The growth hormone (GH)-insulin-like growth factor (IGF-1) axis determines growth during different stages of life. Mutations resulting in deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the release of free IGF-1, leads to problems in growth, reduced bone density and body mass and mild glucose intolerance. To better understand the physiological role of PAPP-A2, we analyzed the metabolic status and lipid metabolism in a mouse model of homoz...
