Mouse Nt5m Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Nt5m Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Nt5m conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Nt5m gene (NCBI Reference Sequence: NM_134029 ; Ensembl: ENSMUSG00000032615 ) is located on Mouse chromosome 11. 5 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 5 (Transcript: ENSMUST00000102695). 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 Nt5m gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-330D24 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 starts from about 36.97% 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: 4418 bp, and the size of intron 2 for 3'-loxP site insertion: 7858 bp. The size of effective cKO region: ~601 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(7101bp) | A(23.59% 1675) | C(22.81% 1620) | T(30.28% 2150) | G(23.32% 1656) 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.

  • Genes in a Refined Smith-Magenis Syndrome Critical Deletion Interval on Chromosome 17P11.2 and the Syntenic Region of the Mouse

Most patients have the same ∼4 Mb interstitial genomic deletion within chromosome 17p11.2. To investigate the molecular bases of the SMS phenotype, we constructed BAC/PAC contigs covering the SMS common deletion interval and its syntenic region on mouse chromosome 11. Comparative genome analysis reveals the absence of all three ∼200-kb SMS-REP low-copy repeats in the mouse and indicates that the evolution of SMS-REPs was accompanied by transposition of adjacent genes. Physical and genetic map comparisons in humans reveal reduced recombination in both sexes. Moreover, by examining the deleted regions in SMS patients with unusual-sized deletions, we refined the minimal Smith-Magenis critical region (SMCR) to an ∼1.1-Mb genomic interval that is syntenic to an ∼1.0-Mb region in the mouse.

Mootha Daniel Solomon Lieber Computational and Experimental Approaches For Evaluating the Genetic Basis of Mitochondrial Disorders Abstract Mitochondria are responsible for some of the cell’s most fundamental biological pathways and metabolic processes, including aerobic ATP production by the mitochondrial respiratory chain. In humans, mitochondrial dysfunction can lead to severe disorders of energy metabolism, which are collectively referred to as mitochondrial disorders and affect approximately 1:5,000 individuals. These disorders are clinically heterogeneous and can affect multiple organ systems, often within a single individual. Symptoms can include myopathy, exercise intolerance, hearing loss, blindness, stroke, seizures, diabetes, and GI dysmotility.

  • Functional Analogy in Human Metabolism: Enzymes with Different Biological Roles Or Functional Redundancy?
    GBE Functional Analogy in Human Metabolism: Enzymes with Different Biological Roles or Functional Redundancy? Rafael Mina Piergiorge1, Antonio Basılio de Miranda2, Ana Carolina Guimaraes~ 1,*, and Marcos Catanho1 1Laboratorio de Genoˆ mica Funcional e Bioinformatica, Fiocruz, Instituto Oswaldo Cruz, Manguinhos, Rio de Janeiro, Brazil 2Laboratorio de Biologia Computacional e Sistemas, Fiocruz, Instituto Oswaldo Cruz, Manguinhos, Rio de Janeiro, Brazil *Corresponding author: E-mail: carolg@fiocruz.br. Accepted: July 4, 2017 Abstract Since enzymes catalyze almost all chemical reactions that occur in living organisms, it is crucial that genes encoding such activities are correctly identified and functionally characterized. Several studies suggest that the fraction of enzymatic activities in which multiple events of independent origin have taken place during evolution is substantial. However, this topic is still poorly explored, and a comprehensive investigation of the occurrence, distribution, and implications of these events has not been done so far. Fundamental questions, such as how analogous enzymes originate, why so many events of independent origin have apparently occurred during evolution, and what are the reasons for the coexistence in the same organism of distinct enzymatic forms catalyzing the same reaction, remain unanswered. Also, several isofunctional enzymes are still not recognized as nonhomologous, even with substantial evidence indicating different evolutionary histories. In this work, we begin to investigate the biological significance of the cooccur- rence of nonhomologous isofunctional enzymes in human metabolism, characterizing functional analogous enzymes identified in metabolic pathways annotated in the human genome. Our hypothesis is that the coexistence of multiple enzymatic forms might not be interpreted as functional redundancy. Instead, these enzymatic forms may be implicated in distinct (and probably relevant) biological roles.

  • Effect of Tenofovir on Nucleotidases and Cytokines in HIV-1 Target Cells
    Effect of Tenofovir on Nucleotidases and Cytokines in HIV-1 Target Cells Nabanita Biswas*, Marta Rodriguez-Garcia, Sarah G. Crist, Zheng Shen, Jack E. Bodwell, John V. Fahey, Charles R. Wira Department of Physiology and Neurobiology, Geisel School of Medicine at Dartmouth, Lebanon, New Hampshire, United States of America Abstract Tenofovir (TFV) has been widely used for pre-exposure prophylaxis of HIV-1 infection with mixed results. While the use of TFV in uninfected individuals for prevention of HIV-1 acquisition is actively being investigated, the possible consequences of TFV exposure for the HIV-target cells and the mucosal microenvironment are unknown. In the current study, we evaluated the effects of TFV treatment on blood-derived CD4+ T cells, monocyte-derived macrophages and dendritic cells (DC). Purified HIV-target cells were treated with different concentrations of TFV (0.001-1.0 mg/ml) for 2 to 24hr. RNA was isolated and RT-PCR was performed to compare the levels of mRNA expression of nucleotidases and pro-inflammatory cytokine genes (MIP3α, IL-8 and TNFα) in the presence or absence of TFV. We found that TFV increases 5’-ecto-nucleotidase (NT5E) and inhibits mitochondrial nucleotidase (NT5M) gene expression and increases 5’ nucleotidase activity in macrophages. We also observed that TFV stimulates the expression and secretion of IL-8 by macrophages, DC, and activated CD4+ T cells and increases the expression and secretion of MIP3α by macrophages. In contrast, TFV had no effect on TNFα secretion from macrophages, DC and CD4+ T cells. Our results demonstrate that TFV alters innate immune responses in HIV-target cells with potential implications for increased inflammation at mucosal surfaces.

SMS is hypothesised to be a contiguous gene syndrome in which the phenotype arises from the haploinsufficiency of multiple, functionally-unrelated genes in close physical proximity, although the true molecular basis of SMS is not yet known. In this study, we have generated the first overlapping and contiguous transcription map of the SMS critical interval, linking the proximal 17p11.2 region near the SMS-REPM and the distal region near D17S740 in a minimum tiling path of 16 BACs and two PACs. Additional clones provide greater coverage throughout the critical region. Not including the repetitive sequences that flank the critical interval, the map is comprised of 13 known genes, 14 ESTs, and six genomic markers, and is a synthesis of Southern hybridisation and polymerase chain reaction data from gene and marker localisation to BACs and PACs and database sequence analysis from the human genome project high-throughput draft sequence.
