    A microRNA screen reveals that elevated hepatic ectodysplasin A expression contributes to obesity-induced insulin resistance in skeletal muscle.
    Nat Med 2017 Nov 6. Epub 2017 Nov 6.
    Department of Neuronal Control of Metabolism, Max Planck Institute for Metabolism Research, Cologne, Germany.
    Over 40% of microRNAs (miRNAs) are located in introns of protein-coding genes, and many of these intronic miRNAs are co-regulated with their host genes. In such cases of co-regulation, the products of host genes and their intronic miRNAs can cooperate to coordinately regulate biologically important pathways. Therefore, we screened intronic miRNAs dysregulated in the livers of mouse models of obesity to identify previously uncharacterized protein-coding host genes that may contribute to the pathogenesis of obesity-associated insulin resistance and type 2 diabetes mellitus.

    Loss-of-function mutations in the Ca(2+) release-activated Ca(2+) channel genes ORAI1 and STIM1 abolish store-operated Ca(2+) entry (SOCE) and result in ectodermal dysplasia with amelogenesis imperfecta. However, because of the limited availability of patient tissue, analyses of enamel mineralization or possible changes in ameloblast function or morphology have not been possible. Here, we generated mice with ectodermal tissue-specific deletion of Stim1 ( Stim1 cKO [conditional knockout]), Stim2 ( Stim2 cKO), and Stim1 and Stim2 ( Stim1/2 cKO) and analyzed their enamel phenotypes as compared with those of control ( Stim1/2(fl/fl)) animals.

    Hairless dog breeds show a form of ectodermal dysplasia characterised by a lack of hair and abnormal tooth morphology. This has been attributed to a semi-dominant 7-base-pair duplication in the first exon of the forkhead box I3 gene (FOXI3) shared by all three breeds. Here, we identified this FOXI3 variant in a historical museum sample of pedigreed hairless dog skulls by using ancient DNA extraction and present the associated dental phenotype. Read More

    Purpose: Anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) is caused by mutations in the NF-κB essential modulator (NEMO) or NF-κB inhibitor, alpha (IKBA) genes. A heterozygous NEMO mutation causes incontinentia pigmenti (IP) in females, while a hemizygous hypomorphic mutation of NEMO causes EDA-ID in males. In general, immunodeficiency is not shown in IP patients. Read More
