Mechanistic and therapeutic insights into the function of N6-methyladenosine in arthritic diseases

ObjectiveArthritis is a class of diseases, characterized by joint and surrounding inflammation, accompanied by joint swelling, pain, dysfunction. According to different factors, arthritis can be divided into osteoarthritis, rheumatoid arthritis, ankylosing spondylitis and so on. N6-methyladenosine (m6A) is the most common internal modification of eukaryotic mRNA and is involved in splicing, stabilization, output and degradation of RNA metabolism. This review systematically summarized current insights into the mechanism of m6A in arthritis.MethodsThe studies related to the involvement of m6A in the pathogenesis of arthritis reported in PubMed, Google scholar, and other open source literatures were investigated to evaluate the important roles of m6A in arhtritis, and the clinical relevances.Results and conclusionsM6A methylation regulators play the roles of writers, erasers, and readers, are crucial for regulating gene expression, and play important roles in many biological processes such as virus replication and cell differentiation. In addition, more and more studies have shown that m6A is closely related to the development of arthritis. As a new therapeutic target for arthritis, m6A has a wide influence on the pathological mechanism of arthritis. However, further research is needed to determine how m6A affects arthritis pathology and its use in target therapy and diagnosis.
