To read the full abstract: J Clin Endocrinol Metab. 2019; 104(7): 2985–2993. PMID: 30844071.Endogenous Cushing syndrome (CS) is a severe condition characterized by excessive glucocorticoid production (1). In 20% of cases, cortisol is secreted autonomously by the adrenal cortex (2). Adrenal CS is mostly caused by unilateral cortisol-producing adrenal ad...

4.9. Low IGF-I bioavailability impairs growth and glucose metabolism in a mouse model of human PAPPA2 p.Ala1033Val mutation

M Fujimoto , M Andrew , L Liao , D Zhang , G Yildirim , P Sluss , B Kalra , A Kumar , S Yakar , V Hwa , A Dauber

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...

5.1. Cartilage-targeted IGF-1 treatment to promote longitudinal bone growth

JC Lui , M Colbert , CSF Cheung , M Ad , A Lee , Z Zhu , KM Barnes , DS Dimitrov , J Baron

Abstract: Mol. Ther. 2019;27:673–680.In brief: The authors developed a fusion protein containing a cartilage-targeting antibody fragment and Insulin-like growth factor 1 (Igf1) and demonstrate that it can stimulate growth plate cartilage at lower and less frequent doses than Igf1. This is a novel approach that paves the way for the development of tissue-specific target...

2.4 Novel FOXA2 mutation causes Hyperinsulinism, Hypopituitarism with Craniofacial and Endoderm-derived organ abnormalities

D Giri , ML Vignola , A Gualtieri , V Scagliotti , P McNamara , M Peak , M Didi , C Gaston-Massuet , S Senniappan

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: Arch Dis Child 2018;103:637-642Management of thyrotoxicosis in children and adolescents remains challenging and treatment varies considerably among institutions. The patient’s age, clinical status and likelihood of remission should be considered when counseling patients and parents. Nevertheless, individual prognosis of antithyroid drug treated Graves’ diseas...

To read the full abstract: J Pediatr 2017; 187:206-12SRS is a clinically heterogeneous imprinting disorder. Although the understanding of its genetic basis has gradually advanced, about 40% of patients still have an unknown molecular defect. In subjects with unknown etiology, diagnosis is primarily clinical, based upon the Netchine-Harbison scoring system (NH-CSS) [31]. How...

To read the full abstract: Nature Communications 2018;9:636We know that good nutrition early in life has profound and long-lasting effects on body weight in later life. Malnutrition during pregnancy or infant formula feeding may be stored on the offspring genome as epigenetic memory and persist into adulthood, thereby influencing the susceptibility to metabolic diseases, such as obes...
