Analysis of Trans Esnps Infers Regulatory Network Architecture
Analysis of trans eSNPs infers regulatory network architecture Anat Kreimer Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2014 © 2014 Anat Kreimer All rights reserved ABSTRACT Analysis of trans eSNPs infers regulatory network architecture Anat Kreimer eSNPs are genetic variants associated with transcript expression levels. The characteristics of such variants highlight their importance and present a unique opportunity for studying gene regulation. eSNPs affect most genes and their cell type specificity can shed light on different processes that are activated in each cell. They can identify functional variants by connecting SNPs that are implicated in disease to a molecular mechanism. Examining eSNPs that are associated with distal genes can provide insights regarding the inference of regulatory networks but also presents challenges due to the high statistical burden of multiple testing. Such association studies allow: simultaneous investigation of many gene expression phenotypes without assuming any prior knowledge and identification of unknown regulators of gene expression while uncovering directionality. This thesis will focus on such distal eSNPs to map regulatory interactions between different loci and expose the architecture of the regulatory network defined by such interactions. We develop novel computational approaches and apply them to genetics-genomics data in human. We go beyond pairwise interactions to define network motifs, including regulatory modules and bi-fan structures, showing them to be prevalent in real data and exposing distinct attributes of such arrangements. We project eSNP associations onto a protein-protein interaction network to expose topological properties of eSNPs and their targets and highlight different modes of distal regulation. -

Given the high attrition rates, high costs and 31 quite slow development of drug discovery, repurposing of known FDA-approved molecules is 32 increasingly becoming an attractive issue in order to quickly find molecules capable of 33 preventing and/or curing COVID-19 patients. Cyclosporin A (CsA), a common anti-rejection 34 drug widely used in transplantation, has recently been shown to exhibit substantial anti- 35 SARS-CoV-2 antiviral activity and anti-COVID-19 effect. -

Genomic Analysis of Mir-21-3P and Expression Pattern with Target Gene in Olive Flounder
eISSN 2234-0742 Genomics Inform 2017;15(3):98-107 G&I Genomics & Informatics https://doi.org/10.5808/GI.2017.15.3.98 ORIGINAL ARTICLE Genomic Analysis of miR-21-3p and Expression Pattern with Target Gene in Olive Flounder Ara Jo1,2, Hee-Eun Lee1,2, Heui-Soo Kim1,2* 1Department of Biological Sciences, College of Natural Sciences, Pusan National University, Busan 46241, Korea, 2Genetic Engineering Institute, Pusan National University, Busan 46241, Korea MicroRNAs (miRNAs) act as regulators of gene expression by binding to the 3’ untranslated region (UTR) of target genes. They perform important biological functions in the various species. Among many miRNAs, miR-21-3p is known to serve vital functions in development and apoptosis in olive flounder. Using genomic and bioinformatic tools, evolutionary conservation of miR-21-3p was examined in various species, and expression pattern was analyzed in olive flounder. Conserved sequences (5’-CAGUCG-3’) in numerous species were detected through the stem-loop structure of miR-21-3p. Thus, we analyzed target genes of miR-21-3p. Among them, 3’ UTR region of PPIL2 gene indicated the highest binding affinity with miR-21-3p based on the minimum free energy value. The PPIL2 gene showed high expression levels in testis tissue of the olive flounder, whereas miR-21-3p showed rather ubiquitous expression patterns except in testis tissue, indicating that miR-21-3p seems to control the PPIL2 gene expression in a complementary repression manner in various tissues of olive flounder. Taken together, this current study contributes to infer the target gene candidates for the miR-21-3p using bioinformatics tools. -

The Transcriptomic Blueprint of Molt in Rooster Using Various Tissues From
Charton et al. BMC Genomics (2021) 22:594 https://doi.org/10.1186/s12864-021-07903-9 RESEARCH Open Access The transcriptomic blueprint of molt in rooster using various tissues from Ginkkoridak (Korean long-tailed chicken) Clémentine Charton1†, Dong-Jae Youm1†, Byung June Ko1, Donghyeok Seol1,2, Bongsang Kim1,2, Han-Ha Chai3, Dajeong Lim3 and Heebal Kim1,2* Abstract Background: Annual molt is a critical stage in the life cycle of birds. Although the most extensively documented aspects of molt are the renewing of plumage and the remodeling of the reproductive tract in laying hens, in chicken, molt deeply affects various tissues and physiological functions. However, with exception of the reproductive tract, the effect of molt on gene expression across the tissues known to be affected by molt has to date never been investigated. The present study aimed to decipher the transcriptomic effects of molt in Ginkkoridak, a Korean long-tailed chicken. Messenger RNA data available across 24 types of tissue samples (9 males) and a combination of mRNA and miRNA data on 10 males and 10 females blood were used. Results: The impact of molt on gene expression and gene transcript usage appeared to vary substantially across tissues types in terms of histological entities or physiological functions particularly related to nervous system. Blood was the tissue most affected by molt in terms of differentially expressed genes in both sexes, closely followed by meninges, bone marrow and heart. The effect of molt in blood appeared to differ between males and females, with a more than fivefold difference in the number of down-regulated genes between both sexes.
