Abstract:
Objective To investigate the role of high mobility group box 1 protein(HMGB1) and the receptor for advanced glycation end products (RAGE) in the pathogenesis of primary gouty arthritis (GA).Methods Enzyme-linked immunosorbent assay(ELISA) was used to determine the level of plasma HMGB1 in 68 acute gout (AG),48 quiescent gout (QG) and 45 healthy control(HC).Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to measure the expression of HMGB1 and RAGE mRNA in the peripheral blood mononuclear cells (PBMCs) in 68 AG,48 QG and 94 HC.One way ANOVA or Wilcoxon test and Spearman's correlations were used for statistical analysis.Results The level of plasma HMGB1,PBMCs HMGB1 and RAGE mRNA were significantly higher in GA than that in HC [(24±34) ng/ml,0.019±0.029,0.000 5±0.000 3] (P<0.05),while the level of plasma HMGB1 and PBMCs HMGB1 mRNA were significantly higher in AG [(222±178) ng/ml,0.235±0.954,0.001 5±0.003 5] than that in QG [(107±176) ng/ml,0.044±0.117,0.001 3±0.000 9] (P<0.05),and the level of PBMCs RAGE mRNA was higher in AG than that in QG (P>0.05).In the GA patients,the level of plasma HMGB1 was positively correlated with white blood cell count,neutrophile granulocytes count,mononuclear cells and erythrocyte sedimentation rate (r=0.34,0.44,0.39,0.33; P<0.05),while negatively correlated with apolipoprotein A1 (r=-0.28,P<0.05); the level of PBMCs HMGB1 mRNA was positively correlated with RAGE mRNA,white blood cell counts,neutrophil counts,lymphocyte counts,serum total cholesterol level,low density lipoprotein level and apolipoprotein B100 level (r=0.29,0.36,0.26,0.28,0.29; P<0.05),while negatively correlated with high density lipoprotein (r=-0.30,P<0.01); the level of PBMCs RAGE mRNA was positively correlated with lymphocyte counts,total cholesterol and apolipoprotein B100 (r=0.35,0.35,0.44; P<0.05).Conclusion HMGB1 and its signaling pathway may play important role in the pathogenesis of gouty arthritis,which may also be involved in the regulation of the lipid metabolism of gout.
