Mouse Trim31 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Trim31 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Trim31 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Trim31 gene (NCBI Reference Sequence: NM_146077 ; Ensembl: ENSMUSG00000058063 ) is located on Mouse chromosome 17. 8 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 8 (Transcript: ENSMUST00000078438). Exon 4~5 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Trim31 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-383N9 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: Homozygous knockout exacerbates the immune response after induced inflammation and in induced peritonitis and reduces the immune response in induced colitis. Exon 4 starts from about 48.78% of the coding region. The knockout of Exon 4~5 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 3534 bp, and the size of intron 5 for 3'-loxP site insertion: 1237 bp. The size of effective cKO region: ~1109 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.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

The syndrome is characterized by partial deletion of chromosome 6, which may arise in a number of ways. Case presentation: We report a 2.8-year old boy presenting with developmental delay and mild dysmorphisms. High-resolution oligonucleotide microarray analysis revealed with high precision a 2.5 Mb interstitial 6p deletion in the 6p22.3 region which encompasses 13 genes. Conclusions: Identifcation and in-depth analysis of cases presenting with mild features of the syndrome will sharpen our understanding of the genetic spectrum of the 6p22.3 deletion.

China ORCID ID: 0000-0002-3640-4280 (F.L.) ABSTRACT It has been challenging to determine the disease-causing variant(s) for most major histocompatibility complex (MHC)- associated diseases. However, it is becoming increasingly clear that regulatory variation is pervasive and a fundamentally important mechanism governing phenotypic diversity and disease susceptibility. We gathered DNase I data from 136 human cells to characterize the regulatory landscape of the MHC region, including 4867 DNase I hypersensitive sites (DHSs). We identified thousands of regulatory elements that have been gained or lost in the human or chimpanzee genomes since their evolutionary divergence. We compared alignments of the DHS across six primates and found 149 DHSs with convincing evidence of positive and/or purifying selection. Of these DHSs, compared to neutral sequences, 24 evolved rapidly in the human lineage. We identified 15 instances of transcription- factor-binding motif gains, such as USF, MYC, MAX, MAFK, STAT1, PBX3, etc., and observed 16 GWAS (genome-wide association study) SNPs associated with diseases within these 24 DHSs using FIMO (Find Individual Motif Occurrences) and UCSC (University of California, Santa Cruz) ChIP-seq data.

  • Galaxy, a Web-Based Framework for the Integration of Genome Analysis
    The Pennsylvania State University The Graduate School Eberly College of Science GALAXY, A WEB-BASED FRAMEWORK FOR THE INTEGRATION OF GENOME ANALYSIS A Dissertation in Biochemistry, Microbiology and Molecular Biology by Daniel James Blankenberg © 2009 Daniel James Blankenberg Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy December 2009 The dissertation of Daniel James Blankenberg was reviewed and approved* by the following: Anton Nekrutenko Associate Professor of Biochemistry and Molecular Biology Dissertation Adviser Chair of Committee Webb C. Miller Professor of Biology Professor of Computer Science and Engineering Ross C. Hardison T. Ming Chu Professor of Biochemistry and Molecular Biology Stephan Schuster Professor of Biochemistry and Molecular Biology Andrey Krasilnikov Assistant Professor of Biochemistry and Molecular Biology Scott Selleck Professor of Biochemistry and Molecular Biology Head of the Department of Biochemistry and Molecular Biology *Signatures are on file in the Graduate School. ii ABSTRACT The standardization and sharing of data and tools are among the biggest challenges facing large collaborative projects and small individual labs alike. Here a compact web application, Galaxy, is described which effectively addresses these issues. It provides an intuitive interface for the deposition and access of data and features a vast number of analysis tools including operations on genomic intervals, utilities for manipulation of multiple sequence alignments and molecular evolution algorithms. By providing a direct link between data and analysis tools, Galaxy allows addressing biological questions that are beyond the reach of existing software. Available both as (1) a publicly available web service providing tools for the analysis of genomic, comparative genomic and functional genomic data and (2) a downloadable package that can be deployed in individual labs, Galaxy attempts to serve both sides of the user distribution: experimental biologists and bioinformaticians.

  • Multifaceted Roles of TRIM Proteins in Colorectal Carcinoma

The pathogenesis of CRC follows a multistage process which together with somatic gene mutations is mainly attributed to the dysregulation of signaling pathways critically involved in the maintenance of homeostasis of epithelial integrity in the intestine. A growing number of studies has highlighted the critical impact of members of the tripartite motif (TRIM) protein family on most types of human malignancies including CRC. In accordance, abundant expression of many TRIM proteins has been observed in CRC tissues and is frequently correlating with poor survival of patients. Notably, some TRIM members can act as tumor suppressors depending on the context and the type of cancer which has been assessed. Mechanistically, most cancer-related TRIMs have a critical impact on cell cycle control, apoptosis, epithelial–mesenchymal transition (EMT), metastasis, and inflammation mainly through directly interfering with diverse oncogenic signaling pathways.

FORWARD GENOMICS OF A COMPLEX TRAIT: MAMMALIAN BASAL METABOLIC RATE by Caleigh Charlebois A Thesis Submitted in Partial Fulfillment of the Requirements for a Degree in Honors (Zoology) The Honors College University of Maine May 2021 Advisory Committee: Danielle Levesque, Assistant Professor of Mammalogy, Advisor Diane Genereux, Postdoctoral Fellow, Broad Institute Jacquelyn Gill, Associate Professor of Paleoecology and Plant Ecology Melissa Ladenheim, Associate Dean of the Honors College Ana Breit, Ph.D. Candidate in Ecology and Environmental Sciences ABSTRACT The significance and nature of basal metabolic rate, a metabolic parameter recorded under specific laboratory conditions, are contested among biologists. Although it was most likely important in the evolution of endothermy in mammals and is associated with many other traits inter- and intra-specifically, the specifics of its heritability and its genetic determinants are largely unknown. Two bioinformatics pipelines are available which can associate traits with their genetic correlates given only whole genomes and phenotypes for each animal. However, extant pipelines were created with binary traits in mind. This leaves a void in our ability to associate continuous traits such as basal metabolic rate with genetic regions that influence them.
