Background: The GH/IGF1 axis has important roles in growth, metabolism, lipid profile and body composition. GH receptor disrupted mice (GHRKO mice) are resistant to the action of GH, thereby, GHRKO mice are dwarf, hypoinsulinemic, hypoglycemic and obese. Consumption of a high fat diet (HFD) induces inflammatory processes in a multitude of peripheral tissues, including hypothalamus.Objective and hypotheses: Our aim was to evaluate the effect of HFD intake...

A New Syndrome Associated with Mutations in the Gene for Pregnancy-Associated Plasma Protein A2 (PAPP-A2) Causing Proportionate Short Stature, High Circulating IGF-I, IGFBP-3, and ALS, Mild Microcephaly, thin Long Bones and Decreased Bone Mineral Density in two Unrelated Families

Background: PAPP-A2 is a metalloproteinase that specifically cleaves IGFBPs 3 and 5. Papp-a2 knock-out (KO) mice show a reduction in body size and skeletal abnormalities.Objective and hypotheses: Our objective is to report two affected families from Spain and USA. The Spanish family presents a homozygous frameshift mutation in exon 3 of the PAPP-A2 gene (c.1927_ 1928insAT, p.D643fs25X) resulting in a premature stop codon, with 2 of 4 si...
