Identity of the pathogenesis, genetic and epigenetic mechanisms of osteoarthritis and rheumatoid arthritis development

Abstract

Osteoarthritis is characterized by heterogeneity of clinical manifestations and, in some cases, a severe progressive course. In this regard, it is important to identify new molecular targets for the treatment of the disease. To determine the role of autoimmune processes, general genetic and epigenetic changes in osteoarthritis and rheumatoid arthritis, as well as to identify osteoarthritis-specific ribonucleic acids (microRNAs), potential targets for targeted therapy, information was searched using scientific platforms PubMed, Scopus, ResearchGate, RSCI over the past 10 years. Although the pathogenesis of rheumatoid arthritis and osteoarthritis differs, evidence has been obtained that identical pathological immune reactions are involved in the mechanism of osteoarthritis and disruption of the expression of 26 identical genes with identical changes in the levels of 13 of them. Changes in the expression of the same microRNAs (miR-140, miR-149, miR-25, miR-146a, miR-16, miR-23b) were detected in osteoarthritis and rheumatoid arthritis. Molecular genetic studies make it possible to find new markers of pathological immune reactions in osteoarthritis, which can be used to treat the disease and prevent its rapid progression, as well as to design targeted therapy using gene expression products as targets. MicroRNAs associated with osteoarthritis and rheumatoid arthritis and involved in the pathogenesis of both diseases may become promising targets for targeted therapy of osteoarthritis and rheumatoid arthritis.
