Multifaceted Functions and Novel Insight Into the Regulatory Role of RNA N(6)-Methyladenosine Modification in Musculoskeletal Disorders

RNA modifications have emerged as key regulators of transcript expression in diverse physiological and pathological processes. As one of the most prevalent types of RNA modifications, N(6)-methyladenosine (m(6)A) has become the highlight in modulation of various diseases through interfering RNA splicing, translation, nuclear export, and decay. In many cases, the detailed functions of m(6)A in cellular processes and diseases remain unclear. Notably, recent studies have determined the relationship between m(6)A modification and musculoskeletal disorders containing osteosarcoma, osteoarthritis, rheumatoid arthritis, osteoporosis, etc. Herein, this review comprehensively summarizes the recent advances of m(6)A modification in pathogenesis and progression of musculoskeletal diseases. Specifically, the underlying molecular mechanisms, detection technologies, regulatory functions, clinical implications, and future perspectives of m(6)A in musculoskeletal disorders are discussed, with the aim to provide a novel insight into their association.
