Diagnostic and prognostic potential of gene microarrays in rheumatoid arthritis.

摘要

Rheumatoid arthritis and juvenile rheumatoid arthritis are histopathologically similar diseases characterized by chronic inflammation of the synovium. The pathogenesis of these diseases is unknown, but the emergence of gene expression profiling provides considerable promise that some of the complex, interconnected immunopathologic events underlying these diseases will soon be better understood. This review will summarize the potential use of gene expression profiling as a diagnostic or prognostic modality, and the potential benefits or limits of such uses. It will conclude with a short discussion of the potential for using gene expression profiling to identify novel targets of therapy in rheumatoid arthritis and related diseases.
