正常和类风湿关节炎关节成纤维样滑膜细胞迁移、侵袭能力的差异
Migration and invasion abilities of normal fibroblast-like synoviocytes versus fibroblast-like synoviocytes in rheumatoid arthritis
摘要
Abstract
BACKGROUND:Fibroblast-like synoviocytes (FLS) in the synovial lining layer are related to the cell proliferation, invasion, migration and apoptosis as well as bone resorption in rheumatoid arthritis. OBJECTIVE:To compare the migration and invasion abilities of FLS (MH7A) in rheumatoid arthritis and normal FLS (HFLS). METHODS:The capacities of cell migration and invasion were evaluated by Transwell cell migration and invasion assays. The primers of the indicated microRNAs were designed and synthesized, and the expression levels of miRNAs were determined by real-time PCR according to the SYBR?PrimeScript?miRNA RT-PCR Kit instruction. RESULTS AND CONCLUSION:MH7A possessed stronger migration and invasion abilities than HFLS. Compared with HFLS, obviously upregulated miR-132, -155, -203, -223 and -124, and significantly downregulated miR-15a, -16, 18a, -19a, -26a and -146a were found in MH7A. These findings suggest that the differentially expressed 11 kinds of rheumatoid arthritis-associated miRNAs participate in the pathogenesis of rheumatoid arthritis probably by enhancing the migration and invasion capacities of MH7A.关键词
