J Clin Endocrinol Metab. 2021;106: e1002–e1013. https://pubmed.ncbi.nlm.nih.gov/33141175/This cross-sectional study applied a commonly used system to classify reproductive aging (Stages of Reproductive Aging Workshop +10 or ‘STRAW +10’) to 338 adolescents and young adult (AYA) cancer survivors (1). The study aimed to evaluate if STRAW +10 correctly identifies premature ovaria...

To read the full abstract: J Clin Invest 2018;128:960-969Mouse models for PWS are urgently needed to facilitate drug development for treatment of hyperphagia and obesity in PWS patients. Here, the authors set out to create a mouse model that better recapitulates human PWS; they chose Snord116 as the target. Snord116 comprises a cluster of noncoding RNAs (ncRNAs) on paternal chromosome 15q11.2. Deletio...

PLoS Genet. 2020; 16(10): e1009069. doi: https://doi.org/10.1371/journal.pgen.1009069The authors used mouse conditional gene knock-out models to investigate the role of Insulin-like growth factor-2 (Igf2) in pancreatic growth and function. When Igf2 was deleted specifically in mesenchyme-derived cells (but not when deleted in exocrine and endocrine cells), the entire pancreas was smal...

To read the full abstract: Genome Res 2018;28:423–431The discovery of a mummified humanoid female skeleton on a shelf in a building in La Noria, Chile in 2003 created enormous scientific and popular interest. Its highly unusual appearance included a length of only 6 inches despite a bone age of 6–7 years old, marked turricephaly (a cone-shaped top of the skull), and reduced number...

PMID: 31618560Despite advances in diabetes care, attaining good glycemic outcomes in patients with type 1 diabetes (T1DM) remains challenging and often is not achieved. For example, the targets set by the American Diabetes Association are met in only a minority of patients. It is hoped th...
