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...

To read the full abstract: Nature 2017;547:419Since the identification of DNA methylation as a master regulator of genomic imprinting more than 20 years ago, it has been the only known mammalian germline imprinting mark. However, recent studies have identified several imprinted genes capable of maintaining paternal allele-specific expression in the absence of oocyte DNA methylation. Here, t...

Mol Cell Endocrinol. 2021 May 1;527:111218. doi: 10.1016/j.mce.2021.111218. PMID: 33636254This study used a high fat and high sucrose diet to generate obese mice. The offspring of these mice showed activation of the unfolding protein response and the heat-shock response in the hypothalamus as early as weaning. This was associated with malformed paraventricular nucleus axonal projections ...

Front Endocrinol 2021; 12:624507. doi: 10.3389/fendo.2021.624507– This systematic review identified 41 Chinese studies totalling 7,853,756 newborns who underwent neonatal CAH screening– The overall incidence of CAH in China was 1/23,024 (95% CI, 1/25,757 to 1/20,815)– Among the CAH patients, the Male:Female ratio was 1.92:1, and 76% presented with salt wasting<p class=...

Childhood obesity is a risk factor for the deve...

To read the full abstract: Nature 2017;548:52-57The central nervous system contributes to ageing. The hypothalamus seems to be particularly important in this process. Recent studies have demonstrated a link between ageing and a decrease of neurogenesis in the hippocampus and the subventricular zone of the lateral ventricle in the brain. Neural stem/progenitor cells (NSC) reside in those regions in ...

In Brief: This phase 1 study in healthy adults assessed the safety and feasibility of transcon-CNP, a novel prodrug that releases native C-type natriuretic peptide (CNP). The novel drug was well tolerated and CNP remained in systemic circulation for >7 days following a single dose.Commentary: Achondroplasia is caused by autosomal activating mutation in the fibroblast growth factor receptor 3 gene (FGFR3) resulting in constitutive receptor ac...

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

PMID: 33982055.Brief Summary: This prospective birth cohort study assessed the impact of maternal glycaemia on infant neurodevelopment at 12 months of age. Maternal glucose levels during pregnancy were associated with infant neurodevelopmental outcomes.High maternal blood glucose levels m...

Brief summary: In this experimental study, a transdermal polymeric microneedle (MN) patch for glucose-responsive closed-loop insulin and glucagon delivery was developed. In chemically-induced type 1 diabetes (T1D) mouse and minipig models, this glucose-responsive dual-hormone MN patch demonstrated tight regulation in blood glucose.The interplay between insulin and glucagon is essential for blood glucose regulation in individuals with or without diabetes....
