Abstract Aging, often considered a result of random cellular damage, can be accurately estimated using DNA methylation profiles, the foundation pan-tissue epigenetic clocks. Here, we demonstrate development universal pan-mammalian clocks, 11,754 arrays from our Mammalian Methylation Consortium, which encompass 59 tissue types across 185 mammalian species. These predictive models estimate age with high accuracy ( r > 0.96). Age deviations correlate human mortality risk, mouse somatotropic...
ABSTRACT Aging is often perceived as a degenerative process resulting from random accrual of cellular damage over time. Despite this, age can be accurately estimated by epigenetic clocks based on DNA methylation profiles almost any tissue the body. Since such pan-tissue have been successfully developed for several different species, we hypothesized that one build pan-mammalian measure in all mammalian species. To address generated data using 11,754 arrays, each profiling up to 36 thousand...
One of the primary aims Functional Annotation ANimal Genomes (FAANG) initiative is to characterize tissue-specific regulation within animal genomes. To this end, we used chromatin immunoprecipitation followed by sequencing (ChIP-Seq) map four histone modifications (H3K4me1, H3K4me3, H3K27ac, and H3K27me3) in eight prioritized tissues collected as part FAANG equine biobank from two thoroughbred mares. Data were generated according optimized experimental parameters developed during quality...
Following the successful creation of a biobank from two adult Thoroughbred mares, this study aimed to recapitulate sample collection in stallions as part Functional Annotation Animal Genome (FAANG) initiative. Both underwent thorough physical, lameness, neurologic, and ophthalmic (including electroretinography) examinations prior humane euthanasia. Epididymal sperm was recovered both immediately postmortem cryopreserved. Aseptically collected full thickness skin biopsies were used isolate,...

1 Abstract A high-quality reference genome assembly, a biobank of diverse equine tissues from the Functional Annotation Animal Genome (FAANG) initiative, and incorporation long-read sequencing technologies, have enabled efforts to build comprehensive tissue-specific transcriptome. The FAANG transcriptome reported here provides up 45% improvement in completeness across tissue types when compared either RefSeq or Ensembl transcriptomes. This also major improvements identification alternatively...
Long non-coding RNAs (lncRNAs) are untranslated regulatory transcripts longer than 200 nucleotides that can play a role in transcriptional, post-translational, and epigenetic regulation. Traditionally, RNA-sequencing (RNA-seq) libraries have been created by isolating transcriptomic RNA via poly-A+ selection. In the past 10 years, methods to perform ribosomal (rRNA) depletion of total developed as an alternative, aiming for better coverage whole RNA, both polyadenylated non-polyadenylated...
Idiopathic hypocalcemia in Thoroughbred (TB) foals causes tetany and seizures is invariably fatal. Based upon the similarity of this disease with human familial hypoparathyroidism occurrence only TB breed, we conducted a genetic investigation on two affected foals. Familial was identified, pedigree analysis suggested an autosomal recessive (AR) mode inheritance. We performed whole-genome sequencing foals, their unaffected dams four unaffected, unrelated horses. Both homozygosity mapping...
ABSTRACT Human DNA methylation profiles have been used successfully to develop highly accurate biomarkers of aging (“epigenetic clocks”). Here, we describe epigenetic clocks for horses, based on CpGs with flanking sequences that are conserved between multiple mammalian species. Methylation levels these were measured using a custom-designed Infinium array (HorvathMammalMethylChip40). We generated 336 from 42 different horse tissues and body parts, which five horses: multi-tissue clock, blood...
Equine neuroaxonal dystrophy/equine degenerative myeloencephalopathy (eNAD/EDM) is an inherited neurodegenerative disorder of unknown etiology. Clinical signs neurological deficits develop within the first year life in vitamin E (vitE) deficient horses. A genome-wide association study (GWAS) was carried out using 670,000 SNP markers 27 case and 42 control Quarter Horses. Two markers, encompassing a 2.5 Mb region on ECA7, were associated with phenotype (p = 2.05 × 10-7 4.72 10-6). Within this...
