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: 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: J Pediatr Endocrinol Metab 2018; 31(6):601-608This article summarizes the findings of likely the largest program of neonatal congenital hypothyroidism (CH) screening in the world. This is a truly impressive effort. The overall incidence of CH was 1/2421, in line with other reports that also observed a relatively high incidence of CH in neonates born in Asia. However, a...

C Wang , Y He , P Xu , Y Yang , K Saito , Y Xia , X Yan , A Hinton Jr , C Yan , H Ding

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...

10.6. Deterioration of glycemic control in youth-onset type 2 diabetes: What are the early and late predictors?

P Zeitler , L El Ghormli , S Arslanian , S Caprio , E Isganaitis , MK Kelsey , RS Weinstock , NH White , K Drews

Brief summary: In this study of 699 youth 10 to < 18 years old with <2 years duration of type 2 diabetes (T2D) at 15 centers across the USA, baseline HbA1c level, and the change in HbA1c level in the first 6 months are predictors of rapid glycemic deterioration. In addition, subsequent loss of control can be predicted based on both baseline and ongoing clinical characteristics.Comment: The population of individuals with youth-onset T2D is heterog...

Brief summary: In the prospective PROCURE study cohort (n=1783), 11-oxygenated androgens were studied in all men with newly diagnosed localized prostate cancer before undergoing radical prostatectomy. Data were related to clinical outcomes (e.g. metastatic disease). Levels of the adrenal androgen precursor 11b-OH-androstenedione were associated with progressive disease, while levels of the predominant bioactive 11-ketotestosterone and its metabolite 11-ketoandrosteron...
