Equine cartilage and bone miRNA repertoires
Short-read NGS technology (SOLIDTM, Life Technologies) was used to establish a comprehensive repertoire of miRNA expressed in either equine cartilage or subchondral bone. Undamaged cartilage and subchondral bone samples from 10-month Anglo-Arabian foals affected by osteochondrosis (OC) were analyzed and compared with samples from healthy foals. Samples were also subjected or not to an experimental mechanical loading to evaluate the role of miRNAs in the regulation of mechano-transduction pathways. Epiphyseal cartilage and subchondral bone miRNome were defined, including about 300 new miRNAs. Differentially expressed miRNAs were identified between bone and cartilage from healthy and OC foals, as well as after the experimental mechanical loading, suggesting that miRNAs play a role in equine OC physiopathology and in the cellular response to biomechanical stress in cartilage and bone.
