Department of Animal Science: Faculty Publications

The horse reference genome assemblies, EquCab2.0 and EquCab3.0, have enabled great advancements in the equine genomics field, from tools to novel discoveries. However, significant gaps of knowledge regarding genome function remain, hindering the study of complex traits in horses. In an effort to address these gaps and with inspiration from the Encyclopedia of DNA Elements (ENCODE) project, the equine Functional Annotation of Animal Genome (FAANG) initiative was proposed to bridge the gap between genome and gene expression, providing further insights into functional regulation within the horse genome. Three years after launching the initiative, the equine FAANG group has generated data …

Transcriptional Analysis Of The Response Of C. Elegans To Ethanol Exposure, Mark G. Sterken, Marijke H. Van Wijk, Elizabeth C. Quamme, Joost A. G. Riksen, Lucinda Carnell, Laura D. Mathies, Andrew G. Davies, Jan E. Kammenga, Jill C. Bettinger

Ethanol-induced transcriptional changes underlie important physiological responses to ethanol that are likely to contribute to the addictive properties of the drug. We examined the transcriptional responses of Caenorhabditis elegans across a timecourse of ethanol exposure, between 30 min and 8 h, to determine what genes and genetic pathways are regulated in response to ethanol in this model. We found that short exposures to ethanol (up to 2 h) induced expression of metabolic enzymes involved in metabolizing ethanol and retinol, while longer exposure (8 h) had much more profound effects on the transcriptome. Several genes that are known to be involved …

Regulation Of Genome Architecture By Chromatin Remodeling In The Brain, Jared Vega Goodman

Arts & Sciences Electronic Theses and Dissertations

Brain development requires exquisite control of gene expression to establish and refine the proper circuitry of the nervous system. Gene expression control is under the purview of several cellular processes, including chromatin regulation in the form of DNA modification, histone modification, and nucleosome remodeling. Chromatin remodeling enzymes are the major effectors of nucleosome remodeling. These enzymes are clearly involved in brain development – mutations in chromatin remodeling enzymes are likely causative for neurodevelopmental disorders of cognition. Chromatin remodeling enzymes have discrete molecular functions and binding profiles and similarly control distinct phases of nervous system maturation. Chd4 is a Chd family …

BACKGROUND: DNA methylation (DNAm) is associated with gene regulation and estimated glomerular filtration rate (eGFR), a measure of kidney function. Decreased eGFR is more common among US Hispanics and African Americans. The causes for this are poorly understood. We aimed to identify trans-ethnic and ethnic-specific differentially methylated positions (DMPs) associated with eGFR using an agnostic, genome-wide approach.

METHODS: The study included up to 5428 participants from multi-ethnic studies for discovery and 8109 participants for replication. We tested the associations between whole blood DNAm and eGFR using beta values from Illumina 450K or EPIC arrays. Ethnicity-stratified analyses were performed using linear …

Genetic Mouse Models Of Liver Disease: Potential Roles Of Zhx2 (Afr1) And Afr2 In Damage And Regeneration, Courtney P. Turpin

Theses and Dissertations--Pharmacology and Nutritional Sciences

The liver is the largest internal organ in mammals and responsible for carrying out various processes, including lipid and carbohydrate metabolism, detoxification of chemicals, and production of serum proteins. Liver damage, which can be caused by a variety of agents including viral infection, environmental toxins, alcohol and excessive dietary fats, can cause dysregulation of these critical functions, leading to worsening liver pathophysiology and impacting health. However, the liver has the remarkable ability to regenerate when damaged. Hepatocytes, which comprise a majority of liver cells, are relatively quiescent under healthy conditions. Upon injury, remaining hepatocytes can proliferate to recover from liver …
