Primary function of Klotho is to form a specific receptor complex with fibroblast growth factor (FGF) receptor 1 (FGFR1) through which it mediates the bio...

The authors claim that his general pattern of growth was like that of modern humans, except that the atlas and mid-thoracic vertebrae matured later and remained at the 5-6-year stage of deve...

Brief summary: This ex vivo/ in vitro study describes a novel regulatory mechanism of androgen receptor (AR) gene transcription by intranuclear actin assembly in droplets upon dihydrotestosterone (DHT) stimulation mediated by DAAM2 (Dishevelled-associated activator of morphogenesis 2) gene.Androgen insensitivity syndrome (AIS) is a common etiology in individuals with 46, XY disorder/differences of sex development, AIS has diverse genita...

Brief summary: Two unrelated patients with a disorder of sex development (DSD) phenotype of partial androgen insensitivity (PAIS) showed heterozygous variants in the DAAM2 gene. Their genital skin fibroblasts showed reduced dihydrotestosterone-stimulated androgen receptor (AR) activity. Extensive basic studies revealed the underlying mechanism of the DSD in which DAAM2-regulated actin polymerization at the ligand-inducible androgen receptor is required for androgen-st...

Brief Summary: This review evaluated the impact of gene mutations in the leptin-melanocortin pathway on short- and long-term outcomes after bariatric surgery, which is still the most effective treatment for severe obesity. This topic is of high clinical relevance, since such mutations play an important role in hunger regulation and energy homeostasis [1, 2] and may therefore confer weight regain after bariatric surgery [3]. To date there have been few publications, often with ...

J Clin Invest. 2020 Aug 3;130(8):4501–4515. doi: 10.1172/JCI136745. PMID: 32453714.This study used mouse models to investigate the role of LIM homeodomain transcription factor Isl1 in pituitary development. It reveals that Isl1 has multiple, critical roles in pituitary gland development. Pituitary-specific Isl1 deletion caused hypopituitarism with increased stem c...

J Clin Endocrinol Metab. 2021; 106(2): e957–e965.https://pubmed.ncbi.nlm.nih.gov/33135723/The authors investigated the reproductive and perinatal outcomes in women with congenital adrenal hyperplasia (CAH) compared with control women in the largest such population-based study to date. Women with CAH had lower birth rates, were more likely to develop gestational diabetes, and had other ...

Pediatr Blood Cancer. 2020; 67: e28617. https://pubmed.ncbi.nlm.nih.gov/32715632/This retrospective single-centre study aimed to develop a final height prediction model based on data from 212 long-term survivors (aged 5-20.4 years) of childhood central nervous system (CNS) tumors who received craniospinal irradiation (CSI) and with a median follow up of 10.2 years. Mean fin...

Diabetes Care. 2020;43(10):2537–2543. doi: 10.2337/dc20-0736.This paper describes a randomized crossover trial in young people with T1D (16–24 years old) comparing two 8-week study periods: the factory-calibrated Dexcom G6 CGM system versus routine self-monitoring of blood glucose (SMBG). CGM improved time within glucose target and reduced HbA1c by 0.76%.The prim...

Hum Genet. 2021 Nov;140(11):1553-1562. doi: 10.1007/s00439-021-02259-2.Brief Summary: This paper describes 5 related Karelian Bear Dogs (KBDs) with a canine hypopituitarism phenotype. Genome-wide association analysis (GWAS) and next-generation sequencing revealed a homozygous candidate gene defect in POU1F1. The study thus presents a novel animal model for human hypopituitarism.</...
