目的观察高浓度葡萄糖对人晶状体上皮细胞HLE-B3迁移的影响。方法将人晶状体上皮细胞HLE-B3分为正常糖浓度组(培养液中糖浓度为5.5 mmol/L)和高糖组(35.5 mmol/L),采用MTT法检测细胞活力、划痕实验检测细胞迁移能力,Western blot 法检测MMP-2、TIMP-2、MMP-9、TIMP-1蛋白表达。结果与正常糖浓度组相比,高糖组细胞活力增殖率在12 h、24 h分别为6.10%、49.77%( P<0.01);结合MTT结果,经校正后高糖组迁移的细胞数较正常糖浓度组有显著性增强( P<0.01);高糖组MMP-2、TIMP-2、MMP-9、TIMP-1表达均较正常糖浓度组增高,且MMP-2/TIMP-2、MMP-9/TIMP-1比值(2.1±0.17、3.79±0.20)亦较正常糖浓度组(1.67±0.23、2.66±0.19)增高(P<0.05)。结论高浓度葡萄糖促进人晶状体上皮细胞的迁移。 MMP-2/TIMP-2和MMP-9/TIMP-1比例失衡可能在高糖诱导的人晶状体上皮细胞迁移过程中起重要作用。
目的觀察高濃度葡萄糖對人晶狀體上皮細胞HLE-B3遷移的影響。方法將人晶狀體上皮細胞HLE-B3分為正常糖濃度組(培養液中糖濃度為5.5 mmol/L)和高糖組(35.5 mmol/L),採用MTT法檢測細胞活力、劃痕實驗檢測細胞遷移能力,Western blot 法檢測MMP-2、TIMP-2、MMP-9、TIMP-1蛋白錶達。結果與正常糖濃度組相比,高糖組細胞活力增殖率在12 h、24 h分彆為6.10%、49.77%( P<0.01);結閤MTT結果,經校正後高糖組遷移的細胞數較正常糖濃度組有顯著性增彊( P<0.01);高糖組MMP-2、TIMP-2、MMP-9、TIMP-1錶達均較正常糖濃度組增高,且MMP-2/TIMP-2、MMP-9/TIMP-1比值(2.1±0.17、3.79±0.20)亦較正常糖濃度組(1.67±0.23、2.66±0.19)增高(P<0.05)。結論高濃度葡萄糖促進人晶狀體上皮細胞的遷移。 MMP-2/TIMP-2和MMP-9/TIMP-1比例失衡可能在高糖誘導的人晶狀體上皮細胞遷移過程中起重要作用。

Objective To investigate the effect of high glucose on migration of human lens epithelial cells (LECs)HLE-B3.Methods HLE-B3 cells were divided into two groups ,normal glucose group (5.5 mmol/L) and high glucose group ( 35.5 mmol/L ) .We employed MTT assay to detect the cell viability , scratch wound assay to evaluate the ability of cell migration ,and western blot assay to determine the expression of the proteins ,MMP-2, TIMP-2,MMP-9 and TIMP-1.Results There were significant differences in cell viability and migration between the normal glucose group and high glucose group .At 12 h and 24 h of the treatment ,the cell viability ratio of high glucose group were respectively 6.10%and 49.77%( P<0.01 ) .Deducting cell proliferation by the cell viability ratio ,the number of migrating cells in high glucose group was significant increased compared with normal glucose group ( P<0.01).In high glucose group,the protein expression ratio of MMP-2 to TIMP-2(2.1 ±0.17)and MMP-9 to TIMP-1 (3.79 ±0.20)were higher than that in normal glucose group (P<0.05).Conclusions High glucose may promote the migration of human lens epithelial cells .The imbalance expressions of MMP-2 to TIMP-2 and MMP-9 to TIMP-1 may play an important role in the migration of LECs .
