Mouse Nars Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Nars Knockout Project (CRISPR/Cas9) Objective: To create a Nars knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Nars gene (NCBI Reference Sequence: NM_001142950 ; Ensembl: ENSMUSG00000024587 ) is located on Mouse chromosome 18. 15 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 15 (Transcript: ENSMUST00000237400). Exon 2~8 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 2 starts from about 2.62% of the coding region. Exon 2~8 covers 33.93% of the coding region. The size of effective KO region: ~7637 bp. The KO region does not have any other known gene.

  • The Staurotypus Turtles and Aves Share the Same Origin of Sex Chromosomes but Evolved Different Types of Heterogametic Sex Determination
    The Staurotypus Turtles and Aves Share the Same Origin of Sex Chromosomes but Evolved Different Types of Heterogametic Sex Determination Taiki Kawagoshi1, Yoshinobu Uno1, Chizuko Nishida2, Yoichi Matsuda1,3* 1 Laboratory of Animal Genetics, Department of Applied Molecular Biosciences, Graduate School of Bioagricultural Sciences, Nagoya University, Nagoya, Japan, 2 Department of Natural History Sciences, Faculty of Science, Hokkaido University, Sapporo, Japan, 3 Avian Bioscience Research Center, Graduate School of Bioagricultural Sciences, Nagoya University, Nagoya, Japan Abstract Reptiles have a wide diversity of sex-determining mechanisms and types of sex chromosomes. Turtles exhibit temperature- dependent sex determination and genotypic sex determination, with male heterogametic (XX/XY) and female heterogametic (ZZ/ZW) sex chromosomes. Identification of sex chromosomes in many turtle species and their comparative genomic analysis are of great significance to understand the evolutionary processes of sex determination and sex chromosome differentiation in Testudines. The Mexican giant musk turtle (Staurotypus triporcatus, Kinosternidae, Testudines) and the giant musk turtle (Staurotypus salvinii) have heteromorphic XY sex chromosomes with a low degree of morphological differentiation; however, their origin and linkage group are still unknown. Cross-species chromosome painting with chromosome-specific DNA from Chinese soft-shelled turtle (Pelodiscus sinensis) revealed that the X and Y chromosomes of S. triporcatus have homology with P. sinensis chromosome 6, which corresponds to the chicken Z chromosome. We cloned cDNA fragments of S. triporcatus homologs of 16 chicken Z-linked genes and mapped them to S. triporcatus and S. salvinii chromosomes using fluorescence in situ hybridization. Sixteen genes were localized to the X and Y long arms in the same order in both species.

Knowledge of the exact processes and effects of the defects in various tRNAs remains incomplete, but a rapidly increasing number of publications over the last decade has shown a growing amount of evidence as to the importance of tRNAs for normal human development, including brain formation and the development and maintenance of higher cognitive functions as well.

Based on our discovery that the glycosaminoglycan dermatan sulfate (DS) displays peculiar affinity to apoptotic cells and autoantigens (autoAgs) and that DS-autoAg complexes cooperatively stimulate autoreactive B1 cell responses, we compiled a database of 751 candidate autoAgs from six human cell types. At least 657 of these have been found to be affected by SARS-CoV-2 infection based on currently available multi-omic COVID data, and at least 400 are confirmed targets of autoantibodies in a wide array of autoimmune diseases and cancer.

  • PROTEOME of the HUMAN CHROMOSOME 18: GENE-CENTRIC IDENTIFICATION of TRANSCRIPTS, PROTEINS and PEPTIDES Addendum to the Roadmap
    PROTEOME OF THE HUMAN CHROMOSOME 18: GENE-CENTRIC IDENTIFICATION OF TRANSCRIPTS, PROTEINS AND PEPTIDES Addendum to the Roadmap: HEALTH ASPECTS 1. PROTEOMICS MEETS MEDICINE At its very beginning, one of the goals of human proteomics became a disease biomarker discovery. Many works compared diseased and normal tissues and liquids to get diagnostic profiles by many proteomics methods. Of them, some cancer proteome profiling studies were considered too optimistic in terms of clinical applicability due to incorrect experimental design [Petricoin], thereby conferring the negative expectations from proteomics in translational medicine [Diamantidis, Nature]. The interlaboratory reproducibility of proteomics pipelines also was considered as a shortage in some papers, e.g. in the works of Bell et al [2009] who tested the proteome MS methods with 20-protein standard sample. These difficulties at the early stage of proteomics were partly caused by the fact that many attempts were mostly directed to the technique adjustment rather than to the clinically relevant result. However, the recent advances in mass-spectrometry including the use of MRM to quantify peptides of proteome [Anderson Hunter 2006] made the community to have a view of cautious optimism on the problem of translation to medicine [Nilsson 2010]. A reproducibility problem stated in [Bell 2009] was shown to be mainly caused by the bioinformatics misinterpretation whereas the MS itself worked properly. The readiness of MRM-based platforms to the clinical use is illustrated by the attempt to pass FDA with the mock application which describes MS-based quantitation test for 10 proteins [Regnier FE 2010]. In its current state, the test has not got a clearance.

  • Novel Genes Associated with Colorectal Cancer Are Revealed by High Resolution Cytogenetic Analysis in a Patient Specific Manner
    Novel Genes Associated with Colorectal Cancer Are Revealed by High Resolution Cytogenetic Analysis in a Patient Specific Manner Hisham Eldai1., Sathish Periyasamy1., Saeed Al Qarni2, Maha Al Rodayyan2, Sabeena Muhammed Mustafa1, Ahmad Deeb3, Ebthehal Al Sheikh2, Mohammed Afzal Khan4, Mishal Johani5, Zeyad Yousef6, Mohammad Azhar Aziz2*. 1 Bioinformatics, King Abdullah International Medical Research Center, Riyadh, Saudi Arabia, 2 Medical Biotechnology, King Abdullah International Medical Research Center, Riyadh, Saudi Arabia, 3 Research Office, King Abdullah International Medical Research Center, Riyadh, Saudi Arabia, 4 Anatomic pathology, National Guard Health Affairs, Riyadh, Saudi Arabia, 5 Endoscopy, National Guard Health Affairs, Riyadh, Saudi Arabia, 6 Surgery, National Guard Health Affairs, Riyadh, Saudi Arabia Abstract Genomic abnormalities leading to colorectal cancer (CRC) include somatic events causing copy number aberrations (CNAs) as well as copy neutral manifestations such as loss of heterozygosity (LOH) and uniparental disomy (UPD). We studied the causal effect of these events by analyzing high resolution cytogenetic microarray data of 15 tumor-normal paired samples. We detected 144 genes affected by CNAs. A subset of 91 genes are known to be CRC related yet high GISTIC scores indicate 24 genes on chromosomes 7, 8, 18 and 20 to be strongly relevant. Combining GISTIC ranking with functional analyses and degree of loss/gain we identify three genes in regions of significant loss (ATP8B1, NARS, and ATP5A1) and eight in regions of gain (CTCFL, SPO11, ZNF217, PLEKHA8, HOXA3, GPNMB, IGF2BP3 and PCAT1) as novel in their association with CRC. Pathway and target prediction analysis of CNA affected genes and microRNAs, respectively indicates TGF-b signaling pathway to be involved in causing CRC.

Coexpression Networks Based on Natural Variation in Human Gene Expression at Baseline and Under Stress Abstract Genes interact in networks to orchestrate cellular processes. Here, we used coexpression networks based on natural variation in gene expression to study the functions and interactions of human genes. We asked how these networks change in response to stress. First, we studied human coexpression networks at baseline. We constructed networks by identifying correlations in expression levels of 8.9 million gene pairs in immortalized B cells from 295 individuals comprising three independent samples. The resulting networks allowed us to infer interactions between biological processes. We used the network to predict the functions of poorly-characterized human genes, and provided some experimental support. Examining genes implicated in disease, we found that IFIH1, a diabetes susceptibility gene, interacts with YES1, which affects glucose transport. Genes predisposing to the same diseases are clustered non-randomly in the network, suggesting that the network may be used to identify candidate genes that influence disease susceptibility.
