Mouse Fcrl1 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Fcrl1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Fcrl1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Fcrl1 gene (NCBI Reference Sequence: NM_153090 ; Ensembl: ENSMUSG00000059994 ) is located on Mouse chromosome 3. 11 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 11 (Transcript: ENSMUST00000163661). Exon 4~7 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Fcrl1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-61O7 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 4 starts from about 10.38% of the coding region. The knockout of Exon 4~7 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 2806 bp, and the size of intron 7 for 3'-loxP site insertion: 2569 bp. The size of effective cKO region: ~2683 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(9183bp) | A(26.23% 2409) | C(23.75% 2181) | T(27.66% 2540) | G(22.36% 2053) 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.

  • Fc Receptors for Immunoglobulins and Their Appearance During Vertebrate Evolution
    Fc Receptors for Immunoglobulins and Their Appearance during Vertebrate Evolution Srinivas Akula, Sayran Mohammadamin¤, Lars Hellman* Department of Cell and Molecular Biology, Uppsala University, The Biomedical Center, Uppsala, Sweden Abstract Receptors interacting with the constant domain of immunoglobulins (Igs) have a number of important functions in vertebrates. They facilitate phagocytosis by opsonization, are key components in antibody-dependent cellular cytotoxicity as well as activating cells to release granules. In mammals, four major types of classical Fc receptors (FcRs) for IgG have been identified, one high-affinity receptor for IgE, one for both IgM and IgA, one for IgM and one for IgA. All of these receptors are related in structure and all of them, except the IgA receptor, are found in primates on chromosome 1, indicating that they originate from a common ancestor by successive gene duplications. The number of Ig isotypes has increased gradually during vertebrate evolution and this increase has likely been accompanied by a similar increase in isotype-specific receptors. To test this hypothesis we have performed a detailed bioinformatics analysis of a panel of vertebrate genomes. The first components to appear are the poly-Ig receptors (PIGRs), receptors similar to the classic FcRs in mammals, so called FcRL receptors, and the FcR c chain. These molecules are not found in cartilagous fish and may first appear within bony fishes, indicating a major step in Fc receptor evolution at the appearance of bony fish. In contrast, the receptor for IgA is only found in placental mammals, indicating a relatively late appearance. The IgM and IgA/M receptors are first observed in the monotremes, exemplified by the platypus, indicating an appearance during early mammalian evolution.

  • Annotation of Functional Variation Within Non-MHC MS Susceptibility Loci Through Bioinformatics Analysis
    Genes and Immunity (2014) 15, 466–476 & 2014 Macmillan Publishers Limited All rights reserved 1466-4879/14 www.nature.com/gene ORIGINAL ARTICLE Annotation of functional variation within non-MHC MS susceptibility loci through bioinformatics analysis FBS Briggs, LJ Leung and LF Barcellos There is a strong and complex genetic component to multiple sclerosis (MS). In addition to variation in the major histocompatibility complex (MHC) region on chromosome 6p21.3, 110 non-MHC susceptibility variants have been identified in Northern Europeans, thus far. The majority of the MS-associated genes are immune related; however, similar to most other complex genetic diseases, the causal variants and biological processes underlying pathogenesis remain largely unknown. We created a comprehensive catalog of putative functional variants that reside within linkage disequilibrium regions of the MS-associated genic variants to guide future studies. Bioinformatics analyses were also conducted using publicly available resources to identify plausible pathological processes relevant to MS and functional hypotheses for established MS-associated variants.

  • A Gene–Environment Interaction Between Smoking and Gene Polymorphisms Provides a High Risk of Two Subgroups of Sarcoidosis Natalia V
    www.nature.com/scientificreports OPEN A Gene–Environment Interaction Between Smoking and Gene polymorphisms Provides a High Risk of Two Subgroups of Sarcoidosis Natalia V. Rivera 1,2*, Karina Patasova1, Susanna Kullberg1, Lina Marcela Diaz-Gallo2, Tomoko Iseda1, Camilla Bengtsson3, Lars Alfredsson3, Anders Eklund1, Ingrid Kockum4, Johan Grunewald1,5 & Leonid Padyukov 2,5 The infuence and efect of cigarette smoking in sarcoidosis is unclear. Here, we evaluated gene- environment interaction between multiple genetic variants including HLA genes and smoking in sarcoidosis defned by two clinical phenotypes, Löfgren’s syndrome (LS) and patients without Löfgren’s syndrome (non-LS). To quantify smoking efects in sarcoidosis, we performed a gene-environment interaction study in a Swedish population-based case-control study consisting of 3,713 individuals. Cases and controls were classifed according to their cigarette smoking status and genotypes by Immunochip platform. Gene-smoking interactions were quantifed by an additive interaction model using a logistic regression adjusted by sex, age and frst two principal components. The estimated attributable proportion (AP) was used to quantify the interaction efect. Assessment of smoking efects with inclusion of genetic information revealed 53 (in LS) and 34 (in non-LS) SNP-smoking additive interactions at false discovery rate (FDR) below 5%. The lead signals interacting with smoking were rs12132140 (AP = 0.56, 95% CI = 0.22–0.90), p = 1.28e-03) in FCRL1 for LS and rs61780312 (AP = 0.62, 95% CI = 0.28–0.90), p = 3e-04) in IL23R for non-LS. We further identifed 16 genomic loci (in LS) and 13 (in non-LS) that interact with cigarette smoking.

  • Mitochondrial Dynamics in Hematopoietic Stem Cells
    Mitochondrial dynamics in hematopoietic stem cells Mariana Justino Lage de Almeida Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2019 © 2019 Mariana Justino Lage de Almeida All rights reserved ABSTRACT Mitochondrial dynamics in hematopoietic stem cells Mariana Justino Lage de Almeida Hematopoietic stem cells (HSCs) take on the extraordinary role of sustaining life-long production of blood cells. Despite their indisputable therapeutic potential, HSC biology is poorly understood, and the field remains limited by the inability to maintain, expand, or generate HSCs in vitro. The aim of this study was to elucidate a particular gap in our understanding of the organellar cell biology of HSCs, specifically the role and function of the mitochondria. Several signaling pathways and biological processes converge onto the mitochondria, yet these organelles were found to be largely dispensable in HSCs on the basis of their predominantly glycolytic metabolism and reports of low mitochondrial content. Our studies show that MitoTracker Green (MTG), a frequently used fluorescent dye to measure mitochondrial mass in hematopoietic populations, is effluxed by HSCs resulting in their systematic and deceptive enrichment in the subset of cells with the lowest MTG fluorescence. Using dye-independent methods we discovered that HSCs have elevated mitochondrial content despite their reliance on glycolysis for ATP production. Moreover, mechanisms of mitochondrial quality control and clearance by autophagy appear to be comparatively lower in HSCs than in any other hematopoietic population we analyzed, suggesting HSCs maintain their mitochondria over time. To investigate the function of mitochondria in HSCs we generated mice with disruption of mitofusins (MFN) 1 and 2.
