J Pediatr Endocrinol Metab 2019; 32(3): 253–258. DOI: 10.1515/jpem-2018-0342• 44,360 neonates were screened for CAH as part of a pilot screening programme in Beijing.• In this prospective study, a CAH incidence of 1:7393 was found, and the most common 21 OHase mutation was c.293-13C/A>G.The authors describe the results of a ...

Brief summary: This randomized, multicenter, controlled, phase II study compared the effects of high-dose (HD) once-weekly PEGylated-recombinant human growth hormone (PEG-rhGH) to low-dose (LD) and to an untreated control group of children with idiopathic short stature (ISS) over a period of 52 weeks. PEG-rhGH was effective in increasing height gain in a dose dependent manner with both doses being well tolerated during the observation period.PEG-rhGH is ...

Brief summary: This paper reviews the associations between cellular iron, ferroptosis and diabetes. It also explores the therapeutic potential of ferroptosis inhibitors in the treatment of diabetic complications.Comment: Ferroptosis is a form of regulated cell death that is characterized by the decreased capacity of antioxidants and the accumulation of lipid reactive oxygen species (ROS).1 This, in turn, causes oxidative damage to cell membran...

Brief summary: Genome-wide small hairpin RNA screening revealed a specialized role for the protein phospholipase D6 (PLD6) located at and highly expressed in the outer mitochondrial membrane of cells in steroidogenic organs. Here PLD6 promotes the entrance of LDL/LDLR complex into the mitochondria where LDL-carried cholesterol is released for steroid hormone biosynthesis.Thereby the mitochondrial redox-sensitive CISD2 protein was found to support the trafficking of the LDL/LDL...

In Brief: The authors of this large international project describe the generation of ‘Zoonomia’, which is a large comparative genomics resource covering 240 different mammalian species. Among their many findings, the authors use this resource to: i) document the vast range of biodiversity on earth, ii) identify 3.6 million genomic sites that are perfectly conserved across species, indicating genes and regulatory regions that are likely essential for mammalian surviva...

Cell Stem Cell. 2022 Feb 3;29(2):328-343.e5. doi: 10.1016/j.stem.2021.11.009. PMID: 34879244.Brief Summary: By applying single-cell RNA sequencing (scRNA-seq) to 112,376 cells of human hypothalamus ranging from 7–20 gestational weeks (GW7–20), the authors produced a spatiotemporal transcriptome atlas of human hypothalamus development and revealed critical regulatory genes control...

Overall, 13.15% (n =847,737) had impaired fasting glucose and 1.18% (n =76,297 women) had diabetes, of whom only...

Brief summary: In this experimental study, pancreas-derived mesenchymal stem cells (PMSCs) were implanted into the kidney capsule of mice with streptozotocin (STZ)-induced diabetes. PMSCs led to increased levels of IL-6 in T-helper 1 and T-helper 17 cells, which transiently activated tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ), which in turn decreased levels of interleukin-17. This was associated with exocrine pancreas regeneration and rescue of ...

Nat Med. 2021 Dec;27(12):2104-2107. https://pubmed.ncbi.nlm.nih.gov/34887578/Brief Summary: This study used single-cell transcriptomic analyses to generate a cell atlas of the human fetal and neonatal small intestine. Notably, the authors identified a subset of fetal enteroendocrine K/L cells (named FIKL) that express high levels of insulin and other beta cell genes.T...
