ABSTRACT
AIM To explore the effects of Shexiang Wulong Pills (Moschus Artifactus,Aconiti Radix Cocta,Pheretima,etc.) drug serum on the expression levels of miR-146a,miR-130 and miR-223 in peripheral blood mononuclear cells (PBMCs) of patients with rheumatoid arthritis (RA).METHODS PBMCs were extracted from blood of 30 cases of RA patients,cells were divided into three groups,blank control group,serum-free groupand Shexiang Wulong Pills drug serum group.After 48 hours,total RNA was extracted,then the expression levels of three miRs were detected by RT-PCR.RESULTS Compared with the serum-free group,the expression levels of miR-146a,miR-130 and miR-223 in the Shexiang Wulong Pills drug serum group were significantly decreased (P ＜ 0.01).CONCLUSION Shexiang Wulong Pills can inhibit inflammation in RA patients by down-regulating the expression levels of miR-223,miR-130 and miR-146a in PBMCs.
ABSTRACT
β-arrestins, important soluble proteins mediating receptor desensitization, have diverse biological functions, such as regulating cell proliferation, cell survival, apoptosis and gene transcription. β-arrestins regulate inflammatory and immune reactions by inhibiting the basal activity of pro-inflammatory transcription factor NF-kB and participating in Toll-like receptors (TLR)/NF-kB signal pathway-mediated NF-kB activation. β-arrestins are involved in the pathogenesis of various inflammatory diseases, such as inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, asthma and so on. The study on β-arrestins will reveal the mechanisms of inflammatory diseases and provide new strategy for clinical treatment. Here we reviewed the recent progress on the role of β-arrestins in regulating the inflammatory diseases.
