摘要: 目的: 研究透明质酸对IL-1β刺激下髁突软骨细胞中HMGB-1表达的影响。方法: 体外分离培养大鼠髁突软骨细胞,将透明质酸(hyaluronic acid,HA)和甘草酸(glycyrrhizin,GL)分别与IL-1β同时加入髁突软骨细胞中,刺激24 h后提取各组细胞总RNA,检测HMGB-1及其相关受体基因表达;提取细胞总蛋白检测HMGB-1蛋白表达。结果: IL-1β刺激髁突软骨细胞24 h后 HMGB-1、TLR2和TLR4基因表达显著升高(P<0.05);IL-1β与HA或GL同时加入刺激的软骨细胞与仅加入IL-1β刺激组相比,HMGB-1、TLR2和TLR4的基因表达较的表达显著降低,HMGB-1蛋白表达也显著降低(P<0.05)。结论: HA可降低IL-1β刺激后髁突软骨细胞中HMGB-1及其受体TLR2、TLR4的表达。

Abstract: Objective: To study the effect of hyaluronic acid (HA) on HMGB-1 expression of chondrocytes with IL-1β stimulation. Methods: TMJ condylar chondrocytes were obtained through in vitro culture. HA and glycyrrhizin (GL) were respectively incubated in chondrocytes with IL-1β stimulation. Total RNA and protein were extracted 24h after stimulation to detect the mRNA expression of HMGB-1 and receptors, and protein expression of HMGB-1. Results: After IL-1β stimulation, the mRNA expressions of HMGB-1, TLR2, and TLR4 were increased. The mRNA expressions of HMGB-1, TLR2, and TLR4 were significantly decreased with the addition of HA or GL in contrast to only IL-1β stimulation (P<0.05). Also the protein expression of HMGB-1 was decreased after HA or GL stimulation (P<0.05). Conclusion: HA could decrease the HMGB-1 and receptors expression of chondrocytes in IL-1β stimulation.
