Project description:We studied extracellular vesicles (EVs) from plasma and synovial fluid in an in vivo model of equine osteoarthritis by investigating longitudinal samples. EVs were isolated using size exclusion chromatography from plasma and synovial fluid of four horses subjected to an osteochondral fragment model of osteoarthritis at 0, 10, 35, 42, 49, 56, 63 days with relevant controls.EV RNA was extracted and subject to small RNA sequencing on an Illumina NovaSeq SP using 100bp, single end reads. After mapping against EquCab.3.0 and miRBase v22.1 differential expression analysis was undertaken with edgeRv3.28 using a quasi-likelihood negative binomial generalized log-linear model. We identified a panel of altered small non-coding RNAs.
Project description:Standardized muscular biopsies of the dorsal compartment of the gluteus medius muscle were performed in 7 horses suffering from equine polysaccharide storage myopathy (PSSM) and 6 sound Norman Cob horses . Gene expression analysis was performed using an equine oligonucleotide microarray which included 384 equine gene probes of the nuclear genome and all the mitochondrial genes.
Project description:Equine lameller tissues were collected to compare normal vs laminitis generated differences in transcriptom level. Keywords: Laminitis, Equine, Diseased foot
Project description:Equine lameller tissues were collected to compare normal vs laminitis generated differences in transcriptom level. Experiment Overall Design: Three Laminitis generated vs three normal Equine hoof tissues were subjected to comparison analysis in transcriptom level by using the Affymetrix Bovine GeneChip. Experiment Overall Design: The reasons for Bovine chip were; 1) Genetic similarity to Equine. Experiment Overall Design: 2) More transcriptom was search at that Affymetrix platform comparing the Equine GeneChip at the time of the study.
Project description:Standardized muscular biopsies of the dorsal compartment of the gluteus medius muscle were performed in 7 horses suffering from equine polysaccharide storage myopathy (PSSM) and 6 sound Norman Cob horses . Gene expression analysis was performed using an equine oligonucleotide microarray which included 384 equine gene probes of the nuclear genome and all the mitochondrial genes. All the samples of PSSM muscles were hybridized against the reference control muscles. This reference was made by pooling together all the mRNA extracted after in vitro transcription from the 6 control muscles of the sound horses. Briefly, the hybridization protocol was adapted from Le Brigand et al. (2006). An open-access long oligonucleotide microarray resource for analysis of the human and mouse transcriptomes. Nucleic Acids Res. 2006 Jul 19;34(12).
Project description:The aim of the study was to investigate the effects of autologous equine serum (AES) incubated for 24 h and autologous conditioned serum (ACS) on inflamed equine chondrocyte pellets in vitro.
Project description:Identify differentially expressed microRNAs in mild and severe equine distal interphalangeal joint osteoarthritis plasma and synovial fluid samples Determine the effects of selected osteoarthritis-related miRNAs on equine chondrocytes in monolayer culture through the application of miRNA agomirs and antagomirs
