Abstract:
BACKGROUND:The etiological factor for rheumatoid arthritis remains unclear, but the effects of nuclear factor-κB on the onset of rheumatoid arthritis have been gradual y paid great attention by rheumatologists.
OBJECTIVE:By using the RNA interference (RNAi) technique to block the signal pathway of nuclear factor-κB
mRNA of human rheumatoid arthritis synovial cells, this study explored its application prospect in the treatment of rheumatoid arthritis.
METHODS:The synovial cells were isolated, digested, and cultured for further use. In accordance with the
design principle of smal interfering RNA (siRNA), target sequences of siRNA of nuclear factor-κB were identified, and siRNA expression vector of nuclear factor-κB was synthesized and constructed. The four pGenesil-1/nuclear factor-κB siRNA expression vectors were transfected into the first passage of synovial cells that wel grew. Blank and negative control groups were set. cells at 12, 24, 48, 72 hours, 5 and 7 days after transfection were col ected, and RNA was extracted. Intracellular nuclear factor-κB mRNA expression levels were measured, and siRNA plasmid vector that could effectively inhibit nuclear factor-κB mRNA expression was screened out.
RESULTS AND CONCLUSION:Nuclear factor-κB highly expressed in synovial cells after human rheumatoid arthritis. 3#pGenesil-1/nuclear factor-κB apparently suppressed nuclear factor-κB mRNA expression in synovial cells with human rheumatoid arthritis. RNAi technique blocked nuclear factor-κB mRNA expression. Therefore, the block of nuclear factor-κB signal pathway might be a good target for rheumatoid arthritis gene therapy.
