RA患者外周血和關(guān)節(jié)炎大鼠破骨細(xì)胞miRNAs異常表達(dá)譜比較及特征性miRNA功能分析
[Abstract]:Aim: to screen the abnormal miRNAs expression profiles of osteoclasts in peripheral blood and osteoclasts of patients with rheumatoid arthritis (RA) and to analyze the characteristic miRNAs and its function of RA. Methods: the miRNAs expression profiles of osteoclasts and normal stromal cells in osteoclasts of induced arthritis rats were cocultured by miRNAs microarray, and the results were verified by; Real time PCR. Bioinformatics method was used to analyze the function of key miRNA. Results: there were 189 miRNAs in peripheral blood of RA patients. Compared with monocytes, there were 211 miRNAs differentially expressed in osteoclasts, of which 10 miRNAs, including miR-15b-5p, expressed. Real time PCR in peripheral blood of RA patients and in osteoclasts of rats. The results were consistent with the results of microarray detection. Bioinformatics analysis showed that the target genes of characteristic miRNA were significantly enriched in signal pathways such as VEGF,MAPK signaling pathway. Conclusion: the abnormal expression of partial miRNAs in peripheral blood of RA patients and osteoclasts in arthritis rats is consistent. It may be the characteristic miRNAs, of RA to interfere with osteoclast differentiation and other pathological processes by regulating related signaling pathways.
