Genes Related to Frontonasal Malformations Are Regulated by miR-338-5p, miR-653-5p, and miR-374-5p in O9-1 Cells
Frontonasal malformations are caused by a failure in the growth of the frontonasal prominence during development. Although genetic studies have identified genes that are crucial for frontonasal development, it remains largely unknown how these genes are regulated during this process. Here, we show that microRNAs, which are short non-coding RNAs capable of targeting their target mRNAs for degradation or silencing their expression, play a crucial role in the regulation of genes related to frontonasal development in mice. Using the Mouse Genome Informatics (MGI) database, we curated a total of 25 mouse genes related to frontonasal malformations, including frontonasal hypoplasia, frontonasal dysplasia, and hypotelorism. MicroRNAs regulating the expression of these genes were predicted through bioinformatic analysis. We then experimentally evaluated the top three candidate miRNAs (miR-338-5p, miR-653-5p, and miR-374c-5p) for their effect on cell proliferation and target gene regulation in O9-1 cells, a neural crest cell line. Overexpression of these miRNAs significantly inhibited cell proliferation, and the genes related to frontonasal malformations (Alx1, Lrp2, and Sirt1 for miR-338-5p; Alx1, Cdc42, Sirt1, and Zic2 for miR-374c-5p; and Fgfr2, Pgap1, Rdh10, Sirt1, and Zic2 for miR-653-5p) were directly regulated by these miRNAs in a dose-dependent manner. Taken together, our results highlight miR-338-5p, miR-653-5p, and miR-374c-5p as pathogenic miRNAs related to the development of frontonasal malformations.
期刊介绍:
The Journal of Developmental Biology (ISSN 2221-3759) is an international, peer-reviewed, quick-refereeing, open access journal, which publishes reviews, research papers and communications on the development of multicellular organisms at the molecule, cell, tissue, organ and whole organism levels. Our aim is to encourage researchers to effortlessly publish their new findings or concepts rapidly in an open access medium, overseen by their peers. There is no restriction on the length of the papers; the full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Journal of Developmental Biology focuses on: -Development mechanisms and genetics -Cell differentiation -Embryonal development -Tissue/organism growth -Metamorphosis and regeneration of the organisms. It involves many biological fields, such as Molecular biology, Genetics, Physiology, Cell biology, Anatomy, Embryology, Cancer research, Neurobiology, Immunology, Ecology, Evolutionary biology.
