CGH analysis of androgenetic haploid embryonic stem cells

Project description:Comparative genomic hybridization (CGH) analysis of androgenetic haploid embryonic stem cells was done with 129/Sv male mouse kidney genomic DNA as reference. The results revealed no consistent copy number variations (CNVs) among the examined cell lines (AH129-5, AH129-N1 and AH129-NC1), except for the global difference on the X chromosome to the male control. Genomic DNA of FACS sorted G0/G1 stage ahES cells was compared with 129/Sv male mouse kidney genomic DNA reference by the NimbleGen Mouse CGH 3x720K Whole-Genome Tiling Array (Build MM9) [100718_MM9_WG_CGH_HX3]

Analysis of Genomic Copy Number Variation in Equine Recurrent Airway Obstruction

Project description:Sixteen severly RAO (Recurrent Airway Obstruction) affected horses were studied. All RAO affected male horses were hybridized with GSM1332974 (Thoroughbred male 1, male reference), and the female horses were with GSM1332975 (Thoroughbred female 2, female reference). Finally results are compared with GSE55266 and two other control horses (SPA-H1-3 and SPA-H1-5) and relatively novel RAO CNVs were reported.

Equine dendritic cells generated with horse serum have enhanced functionality in comparison to dendritic cells generated with fetal bovine serum

Project description:EqMoDC generated with horse serum-supplemented medium showed improved morphological characteristics, higher cell viability and exhibited a more robust performance in the functional T cell assays. The study is further described in A. Ziegler, H. Everett, E. Hamza et al., BMC Vet Research, 2016 A two chip study, comparing monocytes, iMoDC and mMoDC derived in vitro from three horses using total RNA extract

CGH analysis of AG-haESCs (androgenetic haploid embryonic stem cells)

Project description:The genomic DNA sample of AG-haESCs were compared to the C57BL/6J male mouse kidney by comparative genomic hybridization. The data confirmed that the haploid cells sustained genome integrity. The analysis was performed on a NimbleGen Mouse CGH 3x720K Whole-Genome Tiling Array to analyse the copy number variations in AG-haESCs, and the genomic DNA of C57BL/6J male mouse kidney was used as control, which had the same background with haploid ESCs.

A composite map of copy number variable (CNV) regions in the horse genome and the discovery of CNVs involved in equine XY disorders of sexual development

Project description:38 horses from 16 diverse breeds and Przewalski's Horse were used to generate a composite CNV map of equine genome. This map was used to detect novel copy number variation in six horses affected with disorder of sexual development (DSD).

Metabolomic Diagnosis in Horse

Project description:In this project we will investigate the feasibility of metabolomics and to characterize the diversity of metabotypes in the horse, towards discovery of markers and pathways associated with obesity and insulin resistance in the equine model. The collaborative team of researchers assembled for this work have identified horses severely affected with Equine Metabolic syndrome, often characterized by obesity and hyperinsulinemia. These animals are all from the Arabian breed, to control for some genetic background. Horses are age, sex and farm of residence matched with a control animal whenever possible. Carefully controlled collection protocols were utilized to ensure minimal variability in sample age and quality. Blood plasma is submitted for both global LC-MS analysis through the SECIM core facilities. This discovery-based approach will begin to generate new targets for the development of novel therapeutic interventions for the treatment and prevention of obesity, type-2 diabetes as well as related secondary conditions in both humans and horses. Finally, as the first dataset of its kind in the horse, we may also be able to highlight promising new biomarkers for veterinary diagnostic use.

Next Generation Sequencing Transcriptomic Analysis (RNA-seq) of Thoroughbred horse at rest, after exercise and after training

Project description:A single bout of exercise induces changes in gene expression in skeletal muscle. Regular exercise results in an adaptive response involving changes in muscle architecture and biochemistry, and is an effective way to manage and prevent common human diseases such as obesity, cardiovascular disorders and type II diabetes. Our study is a transcriptome-wide analysis of skeletal muscle tissue in a large cohort of untrained Thoroughbred horses before and after a bout of high-intensity exercise and again after an extended period of training. We hypothesized that regular high-intensity exercise training primes the transcriptome for the demands of high-intensity exercise.

Profiling of differential allelic expression in horse, donkey, mule, and hinny placental tissues.

Project description:In eutherian mammals, dosage compensation of X-linked genes is achieved by X chromosome inactivation. X inactivation is random in embryonic and adult tissues, but imprinted X inactivation (paternal X silencing) has been identified in the extraembryonic membranes of the mouse, rat, and cow. Few other species have been studied for this trait, and the data from studies of the human placenta have been discordant or inconclusive. Here, we quantify X inactivation using RNA sequencing of placental tissue from reciprocal hybrids of horse and donkey (mule and hinny). In placental tissue from the equid hybrids and the horse parent the allelic expression pattern was consistent with random X inactivation, and imprinted X inactivation can clearly be excluded. We characterized horse and donkey XIST gene, and demonstrated that XIST allelic expression in female hybrid placental and fetal tissues is negatively correlated with the other X-linked genes chromosome-wide, which is consistent with the XIST-mediated mechanism of X inactivation discovered previously in mice. As the most structurally and morphologically diverse organ in mammals, the placenta also appears to show diverse mechanisms for dosage compensation that may result in differences in conceptus development across species. Examine allelic expression from individual samples of invasive trophoblast tissue of the chorionic girdle from gestation day 33-34 conceptuses of 5 horses, 3 donkeys, 6 mules, and 1 hinny.
