Mouse Arcn1 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Arcn1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Arcn1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Arcn1 gene (NCBI Reference Sequence: NM_145985 ; Ensembl: ENSMUSG00000032096 ) is located on Mouse chromosome 9. 10 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 10 (Transcript: ENSMUST00000034607). Exon 3~5 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Arcn1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-173C11 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 spontaneous mutation have a dilute coat color and neurological defects. Exon 3 starts from about 17.48% of the coding region. The knockout of Exon 3~5 will result in frameshift of the gene. The size of intron 2 for 5'-loxP site insertion: 901 bp, and the size of intron 5 for 3'-loxP site insertion: 4844 bp. The size of effective cKO region: ~2441 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.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

  • Allele-Specific Expression of Ribosomal Protein Genes in Interspecific Hybrid Catfish
    Allele-specific Expression of Ribosomal Protein Genes in Interspecific Hybrid Catfish by Ailu Chen A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 1, 2015 Keywords: catfish, interspecific hybrids, allele-specific expression, ribosomal protein Copyright 2015 by Ailu Chen Approved by Zhanjiang Liu, Chair, Professor, School of Fisheries, Aquaculture and Aquatic Sciences Nannan Liu, Professor, Entomology and Plant Pathology Eric Peatman, Associate Professor, School of Fisheries, Aquaculture and Aquatic Sciences Aaron M. Rashotte, Associate Professor, Biological Sciences Abstract Interspecific hybridization results in a vast reservoir of allelic variations, which may potentially contribute to phenotypical enhancement in the hybrids. Whether the allelic variations are related to the downstream phenotypic differences of interspecific hybrid is still an open question. The recently developed genome-wide allele-specific approaches that harness high- throughput sequencing technology allow direct quantification of allelic variations and gene expression patterns. In this work, I investigated allele-specific expression (ASE) pattern using RNA-Seq datasets generated from interspecific catfish hybrids. The objective of the study is to determine the ASE genes and pathways in which they are involved. Specifically, my study investigated ASE-SNPs, ASE-genes, parent-of-origins of ASE allele and how ASE would possibly contribute to heterosis. My data showed that ASE was operating in the interspecific catfish system. Of the 66,251 and 177,841 SNPs identified from the datasets of the liver and gill, 5,420 (8.2%) and 13,390 (7.5%) SNPs were identified as significant ASE-SNPs, respectively.

Coatomer complex is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins.

Despite their significance to understanding protein folding and function, quantitative analyses of thermodynamic stabilities have been mostly limited to soluble proteins in purified systems. We have used a highly multiplexed proteomics approach, based on analyses of methionine oxidation rates, to quantify stabilities of ~10,000 unique regions within ~3,000 proteins in human cell extracts. The data identify lysosomal and extracellular proteins as the most stable ontological subsets of the proteome.

  • Craniofacial Diseases Caused by Defects in Intracellular Trafficking
    G C A T T A C G G C A T genes Review Craniofacial Diseases Caused by Defects in Intracellular Trafficking Chung-Ling Lu and Jinoh Kim * Department of Biomedical Sciences, College of Veterinary Medicine, Iowa State University, Ames, IA 50011, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-515-294-3401 Abstract: Cells use membrane-bound carriers to transport cargo molecules like membrane proteins and soluble proteins, to their destinations. Many signaling receptors and ligands are synthesized in the endoplasmic reticulum and are transported to their destinations through intracellular trafficking pathways. Some of the signaling molecules play a critical role in craniofacial morphogenesis. Not surprisingly, variants in the genes encoding intracellular trafficking machinery can cause craniofacial diseases. Despite the fundamental importance of the trafficking pathways in craniofacial morphogen- esis, relatively less emphasis is placed on this topic, thus far. Here, we describe craniofacial diseases caused by lesions in the intracellular trafficking machinery and possible treatment strategies for such diseases. Keywords: craniofacial diseases; intracellular trafficking; secretory pathway; endosome/lysosome targeting; endocytosis 1. Introduction Citation: Lu, C.-L.; Kim, J.

  • Fine Mapping of a Region of Chromosome 11Q23.3 Reveals Independent Locus Associated with Risk of Glioma
    Fine Mapping of a Region of Chromosome 11q23.3 Reveals Independent Locus Associated with Risk of Glioma Hongyan Chen1, Bing Sun2, Yingjie Zhao1, Xiao Song1, Weiwei Fan1, Keke Zhou2, Liangfu Zhou2, Ying Mao2*., Daru Lu1*. 1 State Key Laboratory of Genetic Engineering, Fudan-VARI Genetic Epidemiology Center and MOE Key Laboratory of Contemporary Anthropology, School of Life Sciences, Fudan University, Shanghai, China, 2 Neurosurgery Department of Huashan Hospital, Fudan University, Shanghai, China Abstract Background: A single nucleotide polymorphism (SNP) at locus 11q23.3 (rs498872) in the near 59-UTR of the PHLDB1 gene was recently implicated as a risk factor for gliomas in a genome-wide association study, and this involvement was confirmed in three additional studies. Methodology/Principal Findings: To identify possible causal variants in the region, the authors genotyped 15 tagging SNPs in the 200 kb genomic region at 11q23.3 locus in a Chinese Han population-based case-control study with 983 cases and 1024 controls. We found evidence for an association between two independent loci (both the PHLDB1 and the ACRN1 genes) and a predisposition for gliomas. Among the multiple significant SNPs in the PHLDB1 gene region, the rs17749 SNP was the most significant [P = 1.3161026 in a recessive genetic model]. Additionally, two novel SNPs (rs2236661 and rs494560) that were independent of rs17749 were significantly associated with glioma risk in a recessive genetic model [P = 1.3161025 and P = 3.3261025, respectively]. The second novel locus was within the ARCN1 gene, and it was associated with a significantly reduced risk for glioma. Conclusions/Significance: Our data strongly support PHLDB1 as a susceptibility gene for glioma, also shedding light on a new potentially candidate gene, ARCN1.

  • A Peripheral Blood Gene Expression Signature to Diagnose Subclinical Acute Rejection

ABSTRACT Background In kidney transplant recipients, surveillance biopsies can reveal, despite stable graft function, histologic features of acute rejection and borderline changes that are associated with undesirable graft outcomes. Noninvasive biomarkers of subclinical acute rejection are needed to avoid the risks and costs associated with repeated biopsies. Methods We examined subclinical histologic and functional changes in kidney transplant recipients from the prospective Genomics of Chronic Allograft Rejection (GoCAR) study who underwent surveillance biopsies over 2 years, identifying those with subclinical or borderline acute cellular rejection (ACR) at 3 months (ACR-3) post-transplant. We performed RNA sequencing on whole blood collected from 88 indi- viduals at the time of 3-month surveillance biopsy to identify transcripts associated with ACR-3, developed a novel sequencing-based targeted expression assay, and validated this gene signature in an independent cohort.
