Nat Metab. 2022 Feb;4(2):284-299. https://pubmed.ncbi.nlm.nih.gov/35228745/Brief Summary: This study used three high-throughput single-cell technologies to generate a pancreatic islet cell atlas from 24 organ donors with type 1 diabetes (T1D), autoantibody positive and healthy donors. The most remarkable finding was that a subset of exocrine ductal cells appears to acquire a signature of to...

To read the full abstract: Nature. 2019 May;569(7756):409–412.A Denisovan mandible, identified by ancient protein analysis, was found on the Tibetan Plateau. It is at least 160,000 years old and provides direct evidence of the Denisovans outside Siberia.The enigma of the archaic Denisovan started in 2010 when a fraction of a finger was discovered in the D...

Brief summary: This collaborative study identified 13 monoallelic rare loss-of-function (LoF) variants in the serotonin 2C receptor (HTR2C) gene in 19 unrelated individuals with hyperphagia, severe early-onset obesity, and some degree of maladaptive behaviour. The authors used exome sequencing in 2548 individuals with severe obesity and 1117 control individuals without obesity. They found that HTR2C variants cause monogenic obesity by demonstrating t...

Brief Summary:This study assembled a single-cell transcriptomic atlas representing over 2.3 million cells from 17 tissues in mice. Investigations of the scRNA-seq data focussed on effects of sex and androgens on the molecular programs and cellular populations in female and male mice as well as male androgen-deprived, and female androgen-treated mice. Data were then used to gain novel molecular insight into sex-related human disorders as available in the UK Biobank study.<p...

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...

J Clin Endocrinol Metab. 2020 Jun 1;105(6):dgaa131. doi: 10.1210/clinem/dgaa131. PMID: 32170311Genetic control of height has been widely explored using genome-wide association studies (GWAS) in multi-ethnic populations (1-4). Although familial short stature (FSS) is the most common type of short stature, its genetic profile and impact on bone metabolism remains to be investigated. This GWAS...

Nat Metab. 2021 Feb;3(2):228–243. doi: 10.1038/s42255-021-00346-2. PMID: 33619380.In brief: In this genome-wide association study, the authors were able to disentangle the mechanism that uncouples adiposity from its known cardiometabolic complications. They identified 62 genomic loci, at which the same allele is associated with both higher adiposity and lower cardiometabol...

Elife. 2021 Jan. 10:e59142. doi: https://doi.org/10.7554/eLife.59142.Brief Summary: The authors studied genetic mice models to show that pituitary stem cells can secrete WNT ligands to their committed progeny and promote their expansion.The anterior pituitary contains a population of Sox2 expressing stem cells (Sox2+ PSCs), which self-renew and give rise to lineage...

Nat Commun. 2022 Feb 9;13(1):775. doi: 10.1038/s41467-022-28120-2. PMID: 35140214Brief Summary: This in vitro study identified interactions between distinct cell populations of the thyroid gland and immune cells in the context of Hashimoto thyroiditis. The authors provide important new insights into the pathological mechanism of Hashimoto thyroiditis by characterizing the stromal ...

Front Genet. 2022 Mar 3;13:736988. PMID: 35309143, doi: 10.3389/fgene.2022.736988.Brief Summary: This molecular study highlights a novel mechanism of action of Mitogen-activated protein kinase kinase kinase 1 (MAP3K1) in the development of testicular dysgenesis.MAP3K1 is one of the most common genes that has been identified to cause 46, XY DSD and variants are attribu...
