罗格列酮对人肥大细胞株HMC-1细胞粘附功能的影响及机制研究
首发时间:2017-05-13
摘要:目的:观察PPARγ激动剂罗格列酮(RG)对纤维连接蛋白(fibronectin,FIB)诱导的人肥大细胞粘附的影响,并探讨其机制。方法:MTT法和流式细胞术检测RG和GW9662对HMC-1细胞的细胞毒性。将HMC-1细胞分为空白对照组、FIB组、FIB +1μM/LRG组、FIB +3μM/LRG组、FIB +10μM/LRG组,观察各组细胞的粘附功能。另取HMC-1细胞分为空白对照组、FIB组、FIB +10μM/L RG组、 FIB +10μM/L RG+0.1μM/L GW9662组、FIB +10μM/L RG+0.3μM/L GW9662组、 FIB +10μM/L RG+1μM/L GW9662组,观察各组细胞的粘附功能。结果: RG和GW9662对HMC-1细胞没有毒性。RG呈浓度依赖型抑制FIB诱导的HMC-1细胞的粘附。 PPARγ阻断剂GW9662(0.3μM/L及1μM/L)可以阻断RG对HMC-1细胞粘附的抑制作用。结论:PPARγ激动剂罗格列酮通过PPARγ途径抑制FIB诱导的HMC-1细胞的粘附。

The effect and mechanism of Rosiglitazone on HMC-1 Cell adhesion
Abstract:Objective: To investigate the effects and mechanism of a PPARγ ligand, rosiglitazone (RG), on fibronectin (FIB)-induced adhesion in human mast cell-1(HMC-1) cells. Methods: The cytotoxic effect on HMC-1 cells of RG and GW9662 was detected by MTT and flow cytometric analysis.HMC-1 cells were divided into control group, FIB group, FIB +RG(1-10μM/L) group, FIB+RG(10μM/L)+GW9662 (0-1μM/L) group, and cells were allowed to adhesion for 1.5 h, nonadherent cells were carefully removed, adherent cells was calculated using a hemocytometer. Results:RG and GW9662 had no cytotoxity on HMC-1 cells. RG inhibited FIB-induced HMC-1 cell adhesion in a dose-dependent manner, the selective PPARγ antagonist GW9662(0.3μM/Land1μM/L)prevented the inhibitory effect of RG on HMC-1 cells. Conclusion: RG inhibits the adhesion of HMC-1 cells in a PPARγ-dependent mechanism.
