Mouse Tgm3 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Tgm3 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Tgm3 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Tgm3 gene (NCBI Reference Sequence: NM_009374 ; Ensembl: ENSMUSG00000027401 ) is located on Mouse chromosome 2. 13 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 13 (Transcript: ENSMUST00000110299). Exon 2~4 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Tgm3 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-111F6 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for an ENU or null mutation exhibit rough-looking, curly hair. Null mutants display delayed skin barrier formation, loss of vibrissae, and brittle hairs. Exon 2 starts from about 0.38% of the coding region. The knockout of Exon 2~4 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 11279 bp, and the size of intron 4 for 3'-loxP site insertion: 1308 bp. The size of effective cKO region: ~2188 bp. The cKO region does not have any other known gene.

  • B Inhibition in a Mouse Model of Chronic Colitis1
    The Journal of Immunology Differential Expression of Inflammatory and Fibrogenic Genes and Their Regulation by NF-␬B Inhibition in a Mouse Model of Chronic Colitis1 Feng Wu and Shukti Chakravarti2 Fibrosis is a major complication of chronic inflammation, as seen in Crohn’s disease and ulcerative colitis, two forms of inflam- matory bowel diseases. To elucidate inflammatory signals that regulate fibrosis, we investigated gene expression changes under- lying chronic inflammation and fibrosis in trinitrobenzene sulfonic acid-induced murine colitis. Six weekly 2,4,6-trinitrobenzene sulfonic acid enemas were given to establish colitis and temporal gene expression patterns were obtained at 6-, 8-, 10-, and 12-wk time points. The 6-wk point, TNBS-w6, was the active, chronic inflammatory stage of the model marked by macrophage, neu- trophil, and CD3؉ and CD4؉ T cell infiltrates in the colon, consistent with the idea that this model is T cell immune response driven. Proinflammatory genes Cxcl1, Ccl2, Il1b, Lcn2, Pla2g2a, Saa3, S100a9, Nos2, Reg2, and Reg3g, and profibrogenic extra- cellular matrix genes Col1a1, Col1a2, Col3a1, and Lum (lumican), encoding a collagen-associated proteoglycan, were up-regulated at the active/chronic inflammatory stages. Rectal administration of the NF-␬B p65 antisense oligonucleotide reduced but did not abrogate inflammation and fibrosis completely. The antisense oligonucleotide treatment reduced total NF-␬B by 60% and down- regulated most proinflammatory genes. However, Ccl2, a proinflammatory chemokine known to promote fibrosis, was not down- regulated. Among extracellular matrix gene expressions Lum was suppressed while Col1a1 and Col3a1 were not. Thus, effective treatment of fibrosis in inflammatory bowel disease may require early and complete blockade of NF-␬B with particular attention to specific proinflammatory and profibrogenic genes that remain active at low levels of NF-␬B.

Vorotelyak Koltzov Institute of Developmental Biology Russian Academy of Sciences, 119334 Moscow, Russia; [email protected] (E.V.A.); [email protected] (E.A.V.) * Correspondence: [email protected] Received: 1 June 2020; Accepted: 26 August 2020; Published: 30 August 2020 Abstract: Transglutaminases (TGMs) contribute to the formation of rigid, insoluble macromolecular complexes, which are essential for the epidermis and hair follicles to perform protective and barrier functions against the environment. During differentiation, epidermal keratinocytes undergo structural alterations being transformed into cornified cells, which constitute a highly tough outermost layer of the epidermis, the stratum corneum. Similar processes occur during the hardening of the hair follicle and the hair shaft, which is provided by the enzymatic cross-linking of the structural proteins and keratin intermediate filaments. TGM3, also known as epidermal TGM, is one of the pivotal enzymes responsible for the formation of protein polymers in the epidermis and the hair follicle. Numerous studies have shown that TGM3 is extensively involved in epidermal and hair follicle physiology and pathology. However, the roles of TGM3, its substrates, and its importance for the integument system are not fully understood. Here, we summarize the main advances that have recently been achieved in TGM3 analyses in skin and hair follicle biology and also in understanding the functional role of TGM3 in human tumor pathology as well as the reliability of its prognostic clinical usage as a cancer diagnosis biomarker. This review also focuses on human and murine hair follicle abnormalities connected with TGM3 mutations.

  • Computational Derivation of a Molecular Framework for Hair Follicle Biology from Disease Genes Received: 14 September 2017 Rachel K
    www.nature.com/scientificreports OPEN Computational derivation of a molecular framework for hair follicle biology from disease genes Received: 14 September 2017 Rachel K. Severin1, Xinwei Li2, Kun Qian3, Andreas C. Mueller2 & Lynn Petukhova1,4 Accepted: 6 November 2017 Knowledge about genetic drivers of disease increases the efciency of interpreting patient DNA Published: xx xx xxxx sequence and helps to identify and prioritize biological points of intervention. Discoveries of genes with single mutations exerting substantial phenotypic impact reliably provide new biological insight, although such approaches tend to generate knowledge that is disjointed from the complexity of biological systems governed by elaborate networks. Here we sought to facilitate diagnostic sequencing for hair disorders and assess the underlying biology by compiling an archive of 684 genes discovered in studies of monogenic disorders and identifying molecular annotations enriched by them. To demonstrate utility for this dataset, we performed two data driven analyses. First, we extracted and analyzed data implicating enriched signaling pathways and identifed previously unrecognized contributions from Hippo signaling. Second, we performed hierarchical clustering on the entire dataset to investigate the underlying causal structure of hair disorders. We identifed 35 gene clusters representing genetically derived biological modules that provide a foundation for the development of a new disease taxonomy grounded in biology, rather than clinical presentations alone. This Resource will be useful for diagnostic sequencing in patients with diseases afecting the hair follicle, improved characterization of hair follicle biology, and methods development in precision medicine. In an age of precision medicine, faced with interpreting DNA sequence in the genomes of patients, it becomes critical to understand both the spectrum of genes that could be contributing to a particular clinical presentation, and the pathways that are mediating genetic efects.

  • Identification of Candidate Aberrantly Methylated and Differentially
    www.nature.com/scientificreports OPEN Identifcation of candidate aberrantly methylated and diferentially expressed genes in Esophageal squamous cell carcinoma Bao-Ai Han1,8, Xiu-Ping Yang4,8, Davood K Hosseini 3,5, Po Zhang6, Ya Zhang4, Jin-Tao Yu2, Shan Chen2, Fan Zhang7, Tao Zhou 2 ✉ & Hai-Ying Sun2,3 ✉ Aberrant methylated genes (DMGs) play an important role in the etiology and pathogenesis of esophageal squamous cell carcinoma (ESCC). In this study, we aimed to integrate three cohorts profle datasets to ascertain aberrant methylated-diferentially expressed genes and pathways associated with ESCC by comprehensive bioinformatics analysis. We downloaded data of gene expression microarrays (GSE20347, GSE38129) and gene methylation microarrays (GSE52826) from the Gene Expression Omnibus (GEO) database. Aberrantly diferentially expressed genes (DEGs) were obtained by GEO2R tool. The David database was then used to perform Gene ontology (GO) analysis and Kyoto Encyclopedia of Gene and Genome pathway enrichment analyses on selected genes. STRING and Cytoscape software were used to construct a protein-protein interaction (PPI) network, then the modules in the PPI networks were analyzed with MCODE and the hub genes chose from the PPI networks were verifed by Oncomine and TCGA database. In total, 291 hypomethylation-high expression genes and 168 hypermethylation-low expression genes were identifed at the screening step, and fnally found six mostly changed hub genes including KIF14, CDK1, AURKA, LCN2, TGM1, and DSG1. Pathway analysis indicated that aberrantly methylated DEGs mainly associated with the P13K-AKT signaling, cAMP signaling and cell cycle process. After validation in multiple databases, most hub genes remained signifcant. Patients with high expression of AURKA were associated with shorter overall survival.
