Mouse Ifit3 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Ifit3 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Ifit3 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Ifit3 gene (NCBI Reference Sequence: NM_010501 ; Ensembl: ENSMUSG00000074896 ) is located on Mouse chromosome 19. 2 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 2 (Transcript: ENSMUST00000102825). 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 Ifit3 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-111N1 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: Exon 2 is not frameshift exon, and covers 99.59% of the coding region. The size of intron 1 for 5'-loxP site insertion: 3456 bp. The size of effective cKO region: ~2421 bp. The cKO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(8171bp) | A(28.66% 2342) | C(19.35% 1581) | T(29.68% 2425) | G(22.31% 1823) 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.

Read Full License Page 1/19 Abstract Background: Herpes simplex virus type 2 infects the body and becomes an incurable and recurring disease. The pathogenesis of HSV-2 infection is not completely clear. Methods: We analyze the GSE18527 dataset in the GEO database in this paper to obtain distinctively displayed genes(DDGs)in the total sequential RNA of the biopsies of normal and lesioned skin groups, healed skin and lesioned skin groups of genital herpes patients, respectively.The related data of 3 cases of normal skin group, 4 cases of lesioned group and 6 cases of healed group were analyzed.The histospecic gene analysis , functional enrichment and protein interaction network analysis of the differential genes were also performed, and the critical components were selected. Results: 40 up-regulated genes and 43 down-regulated genes were isolated by differential performance assay. Histospecic gene analysis of DDGs suggested that the most abundant system for gene expression was the skin, immune system and the nervous system.Through the construction of core gene combinations, protein interaction network analysis and selection of histospecic distribution genes, 17 associated genes were selected CXCL10,MX1,ISG15,IFIT1,IFIT3,IFIT2,OASL,ISG20,RSAD2,GBP1,IFI44L,DDX58,USP18,CXCL11,GBP5,GBP4 and CXCL9.The above genes are mainly located in the skin, immune system, nervous system and reproductive system.

These authors contributed equally. y Received: 7 March 2020; Accepted: 16 April 2020; Published: 20 April 2020 Abstract: Peste des petits ruminants virus (PPRV) is known to replicate in a wide variety of ruminants causing very species-specific clinical symptoms. Small ruminants (goats and sheep) are susceptible to disease while domesticated cattle and buffalo are dead-end hosts and do not display clinical symptoms. Understanding the host factors that influence differential pathogenesis and disease susceptibility could help the development of better diagnostics and control measures. To study this, we generated transcriptome data from goat and cattle peripheral blood mononuclear cells (PBMC) experimentally infected with PPRV in-vitro. After identifying differentially expressed genes, we further analyzed these immune related pathway genes using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) and selected candidate genes were validated using in-vitro experiments.

  • A Grainyhead-Like 2/Ovo-Like 2 Pathway Regulates Renal Epithelial Barrier Function and Lumen Expansion
    BASIC RESEARCH www.jasn.org A Grainyhead-Like 2/Ovo-Like 2 Pathway Regulates Renal Epithelial Barrier Function and Lumen Expansion † ‡ | Annekatrin Aue,* Christian Hinze,* Katharina Walentin,* Janett Ruffert,* Yesim Yurtdas,*§ | Max Werth,* Wei Chen,* Anja Rabien,§ Ergin Kilic,¶ Jörg-Dieter Schulzke,** †‡ Michael Schumann,** and Kai M. Schmidt-Ott* *Max Delbrueck Center for Molecular Medicine, Berlin, Germany; †Experimental and Clinical Research Center, and Departments of ‡Nephrology, §Urology, ¶Pathology, and **Gastroenterology, Charité Medical University, Berlin, Germany; and |Berlin Institute of Urologic Research, Berlin, Germany ABSTRACT Grainyhead transcription factors control epithelial barriers, tissue morphogenesis, and differentiation, but their role in the kidney is poorly understood. Here, we report that nephric duct, ureteric bud, and collecting duct epithelia express high levels of grainyhead-like homolog 2 (Grhl2) and that nephric duct lumen expansion is defective in Grhl2-deficient mice. In collecting duct epithelial cells, Grhl2 inactivation impaired epithelial barrier formation and inhibited lumen expansion. Molecular analyses showed that GRHL2 acts as a transcrip- tional activator and strongly associates with histone H3 lysine 4 trimethylation. Integrating genome-wide GRHL2 binding as well as H3 lysine 4 trimethylation chromatin immunoprecipitation sequencing and gene expression data allowed us to derive a high-confidence GRHL2 target set. GRHL2 transactivated a group of genes including Ovol2, encoding the ovo-like 2 zinc finger transcription factor, as well as E-cadherin, claudin 4 (Cldn4), and the small GTPase Rab25. Ovol2 induction alone was sufficient to bypass the requirement of Grhl2 for E-cadherin, Cldn4,andRab25 expression. Re-expression of either Ovol2 or a combination of Cldn4 and Rab25 was sufficient to rescue lumen expansion and barrier formation in Grhl2-deficient collecting duct cells.

However, the antiviral defense evolved as a transient, acute phase response and the effects of persistently ongoing stimulation onto cellular homeostasis are not well understood. To study the consequences of long-term innate immune activation, we expressed the NS5B polymerase of Hepatitis C virus (HCV), which in absence of viral genomes continuously produces immune-stimulatory RNAs.

  • Integrated Transcriptome and in Vitro Analysis Revealed Anti-Proliferative
    www.nature.com/scientificreports OPEN Integrated transcriptome and in vitro analysis revealed anti-proliferative efect of citral Received: 26 November 2018 Accepted: 5 March 2019 in human stomach cancer through Published: xx xx xxxx apoptosis Sri Renukadevi Balusamy1, Sivasubramanian Ramani 1, Sathishkumar Natarajan 2, Yeon Ju Kim3 & Haribalan Perumalsamy3 Cancer is the second leading cause of death globally, particularly stomach cancer is third most common causes of cancer death worldwide. Citral possesses anti-tumor activity in various cancer cell lines, However its efect toward stomach cancer and its mechanism of action is have yet to be elucidated. The goal of the present study is to elucidate the role of citral in stomach cancer using transcriptome and in vitro approaches. We performed transcriptome analysis using RNA-seq and explored its capability to persuade apoptosis in AGS human stomach cancer cell lines in vitro. Furthermore, the enrichment and KEGG pathway results suggested that there are several genes involved to induce apoptosis pathway. Furthermore, our study also demonstrated that citral arrested colony formation and migration of cancer cells signifcantly than that of untreated cells. RNA-seq revealed a total of 125 million trimmed reads obtained from both control and citral treated groups respectively. A total number of 612 diferentially expressed genes (DEGs) were identifed which includes 216 genes up-regulated and 396 genes down- regulated genes after treatment. The enrichment analysis identifed DEGs genes from transcriptome libraries including cell death, cell cycle, apoptosis and cell growth. The present study showed the signifcant inhibition efect upon citral by regulating various genes involved in signaling pathways, inhibits metastasis, colony formation and induced apoptosis both in silico and in vitro.

  • The Transcriptome Profile of Human Trisomy 21 Blood Cells
    Antonaros et al. Human Genomics (2021) 15:25 https://doi.org/10.1186/s40246-021-00325-4 PRIMARY RESEARCH Open Access The transcriptome profile of human trisomy 21 blood cells Francesca Antonaros1, Rossella Zenatelli1,2, Giulia Guerri3, Matteo Bertelli3, Chiara Locatelli4, Beatrice Vione1, Francesca Catapano1,5, Alice Gori1, Lorenza Vitale1, Maria Chiara Pelleri1, Giuseppe Ramacieri1, Guido Cocchi6, Pierluigi Strippoli1, Maria Caracausi1* and Allison Piovesan1 Abstract Background: Trisomy 21 (T21) is a genetic alteration characterised by the presence of an extra full or partial human chromosome 21 (Hsa21) leading to Down syndrome (DS), the most common form of intellectual disability (ID). It is broadly agreed that the presence of extra genetic material in T21 gives origin to an altered expression of genes located on Hsa21 leading to DS phenotype. The aim of this study was to analyse T21 and normal control blood cell gene expression profiles obtained by total RNA sequencing (RNA-Seq). Results: The results were elaborated by the TRAM (Transcriptome Mapper) software which generated a differential transcriptome map between human T21 and normal control blood cells providing the gene expression ratios for 17,867 loci. The obtained gene expression profiles were validated through real-time reverse transcription polymerase chain reaction (RT-PCR) assay and compared with previously published data. A post-analysis through transcriptome mapping allowed the identification of the segmental (regional) variation of the expression level across the whole genome (segment-based analysis of expression). Interestingly, the most over-expressed genes encode for interferon-induced proteins, two of them (MX1 and MX2 genes) mapping on Hsa21 (21q22.3).
