Small non-coding RNAs in extracellular vesicles derived from equine synovial fluid and plasma in a model of equine osteoarthritis
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. Overall design: Examination of small non-coding RNAs in longitudianl samples of extracellular vesiscles derived form biofluids in a model of equine osteoarthritis using pairwise comparisons.
