Clinical manifestations of osteoarthritis and the role of silent information regulation 1 in the pathogenesis of osteoarthritis / 中国组织工程研究

ABSTRACT

BACKGROUND:Functional changes of some functional genes have been showed to trigger osteoarthritis, among which, age may be a critical one. OBJECTIVE:To summarize the clinical manifestations of osteoarthritis and the research process of silent information regulation 1 in the occurrence and development of osteoarthritis. METHODS:A computer-based retrieval was performed in the databases of CNKI, PubMed, SpringerLink, and Elsevier Science Direct using the keywords ofosteoarthritis, silent information regulation 1 and cartilagein Chinese and English, respectively. Finally 83 eligible literatures were enrolled for analysis. RESULTS AND CONCLUSION:Deacetylation modification acts on the occurrence and development of osteoarthritis by regulating the expression and biological function of various cytokines. Silent information regulation 1 cannot only regulate body metabolism, inhibit cellapoptosis, repair DNA injury, delay senescence and resist to stress, but also play important roles in the epigenetic modification, gene silencing and signal transduction. Therefore, silent information regulation 1 is involved in the age-related diseases, such as osteoarthritis, osteoporosis, diabetes and Alzheimer's disease. Furthermore, silent information regulation 1 is likely to be an important target of osteoarthritis drugs, and even reverses mechanical stress-induced cartilage injury in the early stage of osteoarthritis.
