Mouse Ifi27 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Ifi27 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Ifi27 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Ifi27 gene (NCBI Reference Sequence: NM_026790 ; Ensembl: ENSMUSG00000064215 ) is located on Mouse chromosome 12. 7 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 7 (Transcript: ENSMUST00000085065). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Ifi27 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-308L21 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 a knock-out allele exhibit protection from induced restenosis. Exon 2 starts from about 100% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 1071 bp, and the size of intron 2 for 3'-loxP site insertion: 989 bp. The size of effective cKO region: ~618 bp. The cKO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(7118bp) | A(27.23% 1938) | C(22.32% 1589) | T(26.95% 1918) | G(23.5% 1673) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

    Gao et al. Hereditas (2021) 158:3 https://doi.org/10.1186/s41065-020-00167-5 RESEARCH Open Access IFI27 may predict and evaluate the severity of respiratory syncytial virus infection in preterm infants Junyan Gao1, Xueping Zhu2, Mingfu Wu1, Lijun Jiang1, Fudong Wang1 and Shan He2,3* Abstract Background: Preterm infants are a special population that vulnerable to respiratory syncytial virus (RSV) infection and the lower respiratory tract infections (LRTIs) caused by RSV could be severe and even life-threating. The purpose of the present study was to identify candidate genes of preterm infants who are susceptible to RSV infection and provide a new insight into the pathogenesis of RSV infection. Methods: Three datasets (GSE77087, GSE69606 and GSE41374) containing 183 blood samples of RSV infected patients and 33 blood samples of healthy controls from Gene Expression Omnibus (GEO) database were downloaded and the differentially expressed genes (DEGs) were screened out. The function and pathway enrichments were analyzed through Database for Annotation, Visualization and Integrated Discovery (DAVID) website. The protein-protein interaction (PPI) network for DEGs was constructed through Search Tool for the Retrieval of Interacting Genes (STRING). The module analysis was performed by Cytoscape software and hub genes were identified. Clinical verification was employed to verify the expression level of top five hub genes among 72 infants including 50 RSV infected patients and 22 non-RSV-infected patients hospitalized in our center. Further, the RSV infected infants with high-expression IFI27 and those with low-expression IFI27 were compared (defined as higher or lower than the median mRNA level).

Methods: The gene expression profiles of GSE15471, GSE19650, GSE32676 and GSE71989 were downloaded from the gene expression omnibus database including pancreatic cancer and normal samples. The differentially expressed genes between the two types of samples were identified with the Limma package using R language. The gene ontology functional and pathway enrichment analyses of differentially-expressed genes were performed by the DAVID software followed by the construction of a protein–protein interaction network. Hub gene identification was performed by the plug-in cytoHubba in cytoscape software, and the reliability and survival analysis of hub genes was carried out in The Cancer Genome Atlas gene expression data. Results: The 138 differentially expressed genes were significantly enriched in biological processes including cell migration, cell adhesion and several pathways, mainly associated with extracellular matrix-receptor interaction and focal adhesion pathway in pancreatic cancer. The top hub genes, namely thrombospondin 1, DNA topoisomerase II alpha, syndecan 1, maternal embryonic leucine zipper kinase and proto-oncogene receptor tyrosine kinase Met were identified from the protein–protein interaction network.

  • Mouse Ifi27l2a Conditional Knockout Project (CRISPR/Cas9)
    https://www.alphaknockout.com Mouse Ifi27l2a Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Ifi27l2a conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Ifi27l2a gene (NCBI Reference Sequence: NM_029803 ; Ensembl: ENSMUSG00000079017 ) is located on Mouse chromosome 12. 4 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 4 (Transcript: ENSMUST00000055071). Exon 3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Ifi27l2a gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-62E20 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 a knock-out allele exhibit normal susceptibility to infection with H1N1 or H7N7 influenza A virus, although sloughing of dead cells into bronchiolar lumen persists somewhat longer after infection than in infected controls. Exon 3 is not frameshift exon, and covers 60.0% of the coding region. The size of intron 2 for 5'-loxP site insertion: 488 bp, and the size of intron 3 for 3'-loxP site insertion: 448 bp. The size of effective cKO region: ~630 bp. The cKO region does not have any other known gene.

  • Telencephalon Transcriptome Analysis of Chronically Stressed Adult Zebrafish
    www.nature.com/scientificreports OPEN Telencephalon transcriptome analysis of chronically stressed adult zebrafsh Received: 22 June 2018 Victoria Huang, Anderson A. Butler & Farah D. Lubin Accepted: 13 December 2018 Chronic stress leads to disruptions in learning and memory processes. The efects of chronic stress Published: xx xx xxxx experience on the adult zebrafsh brain, particularly the memory associated telencephalon brain region, is unclear. The goal of this study was to identify gene expression changes in the adult zebrafsh brain triggered by chronic unpredictable stress. Transcriptome analysis of the telencephalon revealed 155 diferentially expressed genes. Of these genes, some are critical genes involved in learning and memory, such as cdk5 and chrna7, indicating efects of chronic unpredictable stress on zebrafsh memory. Interestingly, several genes were annotated in the Orange domain, which is an amino acid sequence present in eukaryotic DNA-binding transcription repressors. Furthermore, we identifed hsd11b2, a cortisol inactivating gene, as chronic stress-responsive in the whole zebrafsh brain. Collectively, these fndings suggest that memory associated gene expression changes in adult zebrafsh telencephalon are afected by chronic stress experience. Stress experience and anxiety afect physiology, behavior, and brain gene expression across many taxa. Stress response is a short-term adaptation to challenges in the environment, however, when prolonged, leads to det- rimental pathologies and learning and memory impairment1,2. Tese health and behavioral consequences are refected in gene expression changes in the brain, particularly in regions involved in cognitive processes such as the hippocampal region3,4. Like other vertebrates, zebrafsh (Danio rerio) also exhibit behavioral and gene expression responses to stress and anxiety that allow them to be models for cognitive disorders and dysfunction.

  • Analysis of Gene Expression from Systemic Lupus Erythematosus Synovium Reveals Myeloid Cell‑Driven Pathogenesis of Lupus Arthritis Erika L
    www.nature.com/scientificreports OPEN Analysis of gene expression from systemic lupus erythematosus synovium reveals myeloid cell‑driven pathogenesis of lupus arthritis Erika L. Hubbard1*, Michelle D. Catalina1,2, Sarah Heuer1,3, Prathyusha Bachali1, Robert Robl1, Nicholas S. Geraci1,4, Amrie C. Grammer1,5 & Peter E. Lipsky1,5 Arthritis is a common manifestation of systemic lupus erythematosus (SLE) yet understanding of the underlying pathogenic mechanisms remains incomplete. We, therefore, interrogated gene expression profles of SLE synovium to gain insight into the nature of lupus arthritis (LA), using osteoarthritis (OA) and rheumatoid arthritis (RA) as comparators. Knee synovia from SLE, OA, and RA patients were analyzed for diferentially expressed genes (DEGs) and also by Weighted Gene Co‑expression Network Analysis (WGCNA) to identify modules of highly co‑expressed genes. Genes upregulated and/or co‑expressed in LA revealed numerous immune/infammatory cells dominated by a myeloid phenotype, in which pathogenic macrophages, myeloid‑lineage cells, and their secreted products perpetuate infammation, whereas OA was characterized by fbroblasts and RA of lymphocytes. Genes governing trafcking of immune cells into the synovium by chemokines were identifed, but not in situ generation of germinal centers (GCs). Gene Set Variation Analysis (GSVA) confrmed activation of specifc immune cell types in LA. Numerous therapies were predicted to target LA, including TNF, NFκB, MAPK, and CDK inhibitors. Detailed gene expression analysis identifed a unique pattern of cellular components and physiologic pathways operative in LA, as well as drugs potentially able to target this common manifestation of SLE. Systemic lupus erythematosus (SLE) is a complex autoimmune disease in which loss of self-tolerance gives rise to pathogenic autoantibodies causing widespread infammation and tissue damage 1.

Background: While carcinoma-associated growth. In cancers, this microenvironment, or tumor stroma, fibroblasts (CAFs) support tumorigenesis, normal tissue constitutes the backbone of the tumor and is essential for the fibroblasts suppress tumor progression. Mechanisms behind cohesiveness of the tumor tissue the tumor’s ability to thrive conversion of fibroblasts into a CAF phenotype are largely (1). This stroma has considerable similarities with that of unrevealed. Materials and Methods: Transwell co-cultures non-malignant repair processes that are characterized by with fibroblasts in collagen gels and squamous-cell activation of fibroblasts and neoformation of stromal tissue, carcinoma (SCC) cells or normal oral keratinocytes (NOKs) which has led to the concept of a tumor as a "wound that in inserts. Differences in fibroblast global gene expression never heals" (2). were analyzed using Affymetrix arrays and subsequent A fibroblast phenotype characterized by expression of functional annotation and cluster analysis, as well as gene alpha-smooth muscle actin (SMA), platelet-derived growth set enrichment analysis were performed. Results: There were factor receptor-beta (PDGFR-β) and the pericyte marker 52 up-regulated and 30 down-regulated transcript IDs neuron glial antigen 2 (NG2) is regarded as a key cell in the (>2-fold, p<0.05) in fibroblasts co-cultured with SCC tumor stroma (3).
