Here, the authors showed that eliminating ERα in kisspeptin arcuate nucleus neurons resulted in high bone mass phenotype in female mice only.<p clas...

In Brief: The study established a novel rat model with a clinically relevant PLS3 mutation, which replicates the osteoporotic phenotype of early-onset PLS3-related osteoporosis. The findings suggest that treatment with alendronate or teriparatide improves bone mass and microarchitecture, suggesting their potential as effective treatments for early-onset osteoporosis caused by PLS3 mutations.Commentary: This study is an essentia...

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...

To read the full abstract: J Bone Miner Res 2018;33(7):1260-1271Osteogenesis imperfecta (OI) is characterized by early-onset skeletal fragility, often short stature, blue sclerae and some other features. OI is caused by mutations in the two genes encoding type I collagen, namely COL1A1 and COL1A2. Some previous reports have indicated that when the mutation involves the C-propeptide cleavage site in e...

Brief summary: In this experimental study, immunomodulatory microparticles, consisting of encapsulating self-antigens with rapamycin, were injected into mouse lymph nodes to protect against type 1 diabetes (T1D) and islet graft rejection. Antigens and rapamycin were both required for maximal efficacy and they induced durable tolerance, accompanied by expansion of antigen-specific regulatory T cells (Treg) in both treated and untreated lymph nodes.Antigen...

Brief summary: The Human Pangenome Reference Consortium reports a first draft of the human pangenome reference due to replace the existing reference GRCh38 (1, 2). It is an updated, high-quality, graph-based, telomere-to-telomere representation of global genomic diversity including common variants (single-nucleotide variants, structural variants and functional elements).The human reference genome is the fundamental, open-access resource of modern human g...

To read the full abstract: Nat Commun. 2020;11:1343.Li et al. describe a new genetic mechanism causing Pendred syndrome and extend evidence for an oligogenic origin of congenital hypothyroidism (CH). Autosomal recessive mutations in Pendrin (PDS/SCL26A4 ) were described in 1997 to cause Pendred syndrome [1]. However, over the years patients with either only heterozygous or even no mutation in PDS/SLC26A4 have been diag...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...
