J Clin Endocrinol Metab. 2020 Dec 1;105(12):dgaa633. doi: 10.1210/clinem/dgaa633. PMID: 32898218.In this study, low risk pregnant women had an ‘early’ OGTT at 18-20 weeks of gestation and these results were correlated with the standard OGTT at 24-28 weeks. Pregnant women with Gestational diabetes mellitus (GDM) who had early OGTT still had a higher risk of delivering macrosomic in...

Nat Commun. 2020;11:4807. doi: 10.1038/s41467-020-18497-3.This interesting paper illustrates the potential of machine learning to improve the sensitivity and specificity of routine techniques in clinical practice if large cohorts for training and validation of models are used. Yu et al. present a transfer learning model (machine learning approach to solve research problems by r...

The IGF system is mainly known for its role in the regulation of growth, development and metabolism. A possible role of IGF-I in inflammation has recently been proposed [1, 2], whereas the e...

In Brief: The authors use cell-tracing of Axin2-positive chondroprogenitor cells in the resting zone during and after food restriction to demonstrate that nutrient availability influences the balance between accumulation and differentiation of resting zone chondrocytes and that this is influenced by Igf-1.Commentary: Catch-up growth is the rapid growth that occurs after growth-inhibiting conditions have been cured or removed. The molecular mechanism for ...

Front Endocrinol (Lausanne). 2021 Jun 11;12:657873. doi: 10.3389/fendo.2021.657873. PMID: 34177802.Brief Summary: This is a single case report describing a possible new candidate gene (ADCY7) for congenital hyperinsulinism. Mutations in the ADCY7 gene may be a new cause of congenital hyperinsulinism but more cases are needed and the molecular mechanisms studied in more det...

To read the full abstract: Nature Genetics 2018; 50: 26–41These authors combined data from 125 cohorts comprising more than 700,000 individuals to discover rare and low-frequency (R/LF) coding single nucleotide variants (SNVs) associated with BMI, thereby identifying novel potential targets for the treatment of obesity. They identified 14 R/LF coding SNVs in 13 genes associated with...

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...

Brief summary: This in vitro study reports that fully potent oocytes were generated from pluripotent stem cells of the tail of a sexually mature male mouse. These oocytes were able to give rise to offspring after fertilization.A particular challenge in the care of DSD patients in adulthood is the optimization of fertility potential. Fertility outcome is significantly reduced in all types of DSD depending on the underlying etiology as well as the...

Genes Dev. 2021;35(5–6):367–378. doi: 10.1101/gad.345686.120.The longstanding concept of thyroid hormone (TH) action is summarized as the canonical switch model. This study adds important aspects of TH action to our current understanding, modifying this longstanding switch model to a “shift” model.According to the current concept, TH dependent gene...
