To read the full abstract: Endocrinology. 2019;160:1363–1376.Pregnancy-associated plasma protein A2 (PAPP-A2) is a metalloproteinase which, by cleaving IGFBP-3 and IGFBP-5, releases free IGF-I from the ternary complexes and regulates its bioavailability. PAPPA2 gene mutations (p.D643fs25* and p.Ala1033Val) have recently been described in various members of two unrelated fam...

To read the full abstract: Hum Mol Genet. 2017 Nov 15;26(22):4315-4326These two papers describe the association of heterozygous FOXA2 mutations with hypopituitarism and hyperinsulinism. The forkhead/winged helix transcription factor Foxa2 is a major upstream regulator of Pdx1, a transcription factor necessary for pancreatic development and also plays a role in the developmental biology of the pituit...

To read the full abstract: Cell Metab. 2018, 27, 226-236Upon sustained cold exposure, white adipose tissue (WAT) can undergo substantial remodeling, characterized by the appearance of thermogenic brown-like or beige adipocytes. This “browning” of white fat depot also happens in humans and is associated with anti-obesity and anti-diabetic effects. This is why WAT “browning&#...

To read the full abstract: Nature Communications 2018;9:1544Obesity prevalence is generally higher in women than in men, and there is also a sex difference in body fat distribution. Sex differences in obesity can be explained in part by the influence of gonadal steroids on body composition and appetite; however, behavioural, and socio-cultural factors may also play a role. Here is th...

Brief summary: This study identified nitric oxide synthase 1 (NOS1) heterozygous missense variants in 6 patients with hypogonadotropic hypogonadism. Altered minipuberty and puberty as well as cognitive impairment were observed in NOS1 deficient mice.Nitric oxide (NO) is produced under the control of NO synthase in hypothalamic neurons. NO plays a crucial role in regulating gonadotropin-releasing hormone (GnRH) secretion, acting as a strong inhibitory sig...
