J Bone Miner Res 36, 1387–1402. (2021)Abstract: https://pubmed-ncbi-nlm-nih-gov/33724538/In brief: Premature growth plate closure under anti-hedgehog treatment is caused by impaired retinoic acid metabolism in growth plate progenitor cells. In this mouse model, administration of retinoic acid receptor blockers rescued the phenotype and normalized growth plate maturation.<p class="a...

PMID: 31393570.Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency has an incidence of 1 in 10 000 to 20 000 in most populations. It is one of the most common monogenic autosomal recessive disorders (1). It has been suggested that the condition is common because it may confe...

In rodents, this was achieved by inserting weighted balloons into the abdomina...

To read the full abstract: Nat Commun. 2018;9:4455.Here, the largest genome-wide association study (GWAS) to date on thyroid function and dysfunction, in 72,167 individuals testing 8 million genetic variants, substantially increased the number of loci that are involved in the regulation of thyroid function. It provides functional evidence that two newly identified genes are involved in t...

To read the full abstract: J Clin Endocrinol Metab. 2018;103:3720–28.This nationwide prospective surveillance study aimed to estimate the performance of the current UK recommended TSH threshold (10 mU/L on day 5 after birth) for newborn blood spot screening compared to lower thresholds: 8 mU/L and 6 mU/L. Over a 12-month period, the authors included all patients with positive TSH ba...

Brief Summary: This study provides evidence for the role of miR-137/325 in obesity-induced hypogonadism (OIH) and metabolic dysfunction.Obesity is associated with different forms of gonadal and reproductive dysfunction, including central male hypogonadism (1, 2). Although weight loss is the ideal therapeutic strategy for patients with OIH, significant weight loss is usually difficult to achieve only with lifestyle changes. Hence, androgen administration ...

Brief Summary: This study shows that obesity induces mitochondrial fragmentation and reduces oxidative capacity in white adipocytes through the activation of the small GTPase RalA. Targeted deletion of RalA in these cells prevents mitochondrial fragmentation, improves energy expenditure, and protects against obesity-induced metabolic dysfunctions, highlighting the critical role of RalA in obesity-related mitochondrial and metabolic abnormalities.Previous...
