Aim: To identify differential methylation related to prescribed opioid use. Methods: This study examined whether blood DNA methylation, measured using Illumina arrays, differs by recent opioid medication use in four population-based cohorts. We meta-analyzed results (282 users; 10,560 nonusers) using inverse-variance weighting. Results: Differential methylation (false discovery rate <0.05) was observed at six CpGs annotated to the following genes: KIAA0226, CPLX2, TDRP, RNF38, TTC23 and GPR179. Integrative epigenomic analyses linked implicated loci to regulatory elements in blood and/or brain. Additionally, 74 CpGs were differentially methylated in males or females. Methylation at significant CpGs correlated with gene expression in blood and/or brain. Conclusion: This study identified DNA …

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 …

Epigenetic Mechanisms As Drivers Of Environmental Responses In Stony Corals, Javier A. Rodriguez Casariego

The current pace of anthropogenic global change is imposing unprecedented conditions to biological systems. Coral reef ecosystems are particularly sensitive to the rapid increase in thermal anomalies and the changes in water chemistry caused by global change. However, although their decline has been documented worldwide, there are signs suggesting that stony corals harbor greater phenotypic plasticity than previously expected, sparking the interest in the study acquired non-genetic modifications (e.g., epigenome, microbiome) potentially increasing their resilience to global change, and constituting one of the main targets for intervention.

Epigenetics constitutes an exciting frontier to understand how the environment influences the regulation …

Effects Of Suv39h1 And Suv420h1/H2 On Programmed Genome Rearrangement In Petromyzon Marinus, Claire A. Scott

Oswald Research and Creativity Competition

The sea lamprey (Petromyzon marinus), diverged from the vertebrate lineage roughly 550 million years ago, prior to the evolution of several major morphological features such as jaws and paired fins/appendages. Lamprey therefore provides a comparative perspective that can be used to study the evolution of differences in genome regulation, including epigenetics and programmed genome rearrangement (PGR). Programmed genome rearrangement is a unique regulatory mechanism wherein specific genes are effectively turned off by completely eliminating their sequences from the genome. Through PGR, lamprey delete approximately 20% of their genome from all somatic cells, with these specific sequences being only …
