DNA methylation is an epigenetic regulatory mechanism that plays an essential role in mediating biological processes and determining phenotypic plasticity in organisms. Although the horse reference genome and whole transcriptome data are publically available the global DNA methylation data are yet to be known. We report the first genome-wide DNA methylation(More)
Working dogs serve as military watch dogs, search dogs, rescue dogs, and guide dogs with un-come-at-able character. They are drafted by in-training examination including concentration, capacity for locomotion, boldness and earthly desires. In this study, genetic diversity and relationships among two groups of working dogs (pass and fail group in-training(More)
SINE-VNTR-Alu (SVA) elements are present in hominoid primates and are divided into 6 subfamilies (SVA-A to SVA-F) and active in the human population. Using a bioinformatic tool, 22 SVA element-associated genes are identified in the human genome. In an analysis of genomic structure, SVA elements are detected in the 5' untranslated region (UTR) of HGSNAT(More)
Athletic performance is an important criteria used for the selection of superior horses. However, little is known about exercise-related epigenetic processes in the horse. DNA methylation is a key mechanism for regulating gene expression in response to environmental changes. We carried out comparative genomic analysis of genome-wide DNA methylation profiles(More)
There are more than 400 pure dog breeds developed through intentional artificial selection and purebred breeding. Purebred animals have higher risk of inbreeding depression and hereditary diseases. We investigated the genetic diversity and structure of three dog breeds in South Korea by using 12 microsatellite loci for one Korean native dog breed, Sapsaree,(More)
Although humans and canines exhibit similar behavioral features, it is not easy to identify the corresponding behavioral phenotypes. The variable number of tandem repeats (VNTR) in intron 4 of the tyrosine hydroxylase (TH) gene is related to two characteristics, namely, impulsive activity and inattention. The TH genes are defined by three genotypes: type(More)
Canine and human behavior are shaped by similar evolutionary processes, yet the identification of the behavioral phenotype is often difficult. A widely used method relies on breed stereotypes provided by experts such as dog trainers. To reveal a valid association between behavior and genetic factors, an association study of behavioral phenotyping and(More)
