摘要:
目的 探讨高钙培养对人晶状体上皮细胞(human lens epithelial cells,HLEC)株SRA01/04氧化应激水平的影响。方法 选取处于对数生长期的HLEC均匀接种96孔板(每孔2×103个细胞),对照组:正常培养的HLEC,实验组:正常培养的HLEC+ CaCl2(3 mmol·L-1、5 mmol·L-1、7 mmol·L-1、9 mmol·L-1、11 mmol·L-1、13 mmol·L-1、15 mmol·L-1、17 mmol·L-1、19 mmol·L-1)培养0 h、12 h、24 h、36 h,采用CCK-8法检测各组细胞存活率。利用定量检测试剂盒测量细胞内超氧化物歧化酶(superoxide dismutase,SOD)、总谷胱甘肽(total-glutathione,T-GSH)含量及氧化型谷胱甘肽(oxidized glutathione,GSSG)/T-GSH比值的变化。结果 3 mmol·L-1、5 mmol·L-1、7 mmol·L-1 CaCl2处理SRA01/04细胞24 h,细胞存活率随CaCl2浓度增高先呈显著下降趋势,当浓度增高到9 mmol·L-1后细胞存活率又逐渐恢复,各实验组HLEC活力差异有统计学意义(P<0.05)。对照组细胞活力(0.592±0.055)与15 mmol·L-1CaCl2组(0.293±0.020)细胞活力相比差异有统计学意义(t=7.811,P<0.05)。CaCl2引起HLEC凋亡的最合适浓度和作用时间为15 mmol·L-1处理24 h。与对照组相比,15 mmol·L-1CaCl2处理24 h后,细胞核碎裂、溶解,细胞内SOD活力增高(t=-6.417,P<0.05),T-GSH含量下降(t=13.816,P<0.05),GSSG/T-GSH比值增高(t=-4.396,P<0.05)。结论 CaCl2诱导的高钙状态抑制HLEC的活力,引起细胞内SOD活力和GSSG含量增加,诱发并加剧细胞内氧化应激反应。
Abstract:
Objective To investigate the influence of calcium elevation on oxidative stress in human lens epithelial cells (HLEC) SRA01/04.Methods The cells (2×103 cells/well) which in the period of logarithmic phase were seeded into 96-well plates with three replicates for the two groups;and in the experimental group,SRA01/04 cells were exposed to a CaCl2 concentration gradient (3 mmol·L-1,5 mmol·L-1,7 mmol·L-1,9 mmol·L-1,11 mmol·L-1,13 mmol·L-1,15 mmol·L-1,17 mmol·L-1,19 mmol·L-1) for 0 h,12 h,24 h,36 h;while the cells in the control group were cultured in complete 1640 medium.Cell counting kit-8(CCK-8) assay was used to measure cell viability.The levels of intracellular superoxide dismutase (SOD),glutathione (GSH) content and oxidized glutathione (GSSG) / total glutathione (T-GSH) were determined by using the microplate-reader method with the commercial total/oxidized glutathione and sod quantification kit.Results At first,the survival rate of SRA01/04 cells treated with 3 mmol·L-1,5 mmol·L-1,7 mmol·L-1 CaCl2 for 24 h showed a significant decrease with the increase of CaCl2 concentration by CCK-8 assays,but gradually increased when the concentration increased to 9 mmol·L-1,and the difference approached statistical significance (P<0.05).Meanwhile,there was significant difference in the viability of the control group (0.592±0.055) and cells exposed to 15 mmol·L-1 CaCl2 (0.293±0.02) (t=7.811,P<0.05).Cell treatment with 15 mmol·L-1 CaCl2 for 24 h was the most appropriate condition for HLEC apoptosis,followed by the appearance of nuclear fragmentation and dissolution,enhanced intracellular SOD viability(t=-6.417,P<0.05),decreased T-GSH content(t=13.816,P<0.05),and increased ratio of GSSG/T-GSH (t=-4.396,P<0.05) when compared with the control group,and the differences were statistically significant.Conclusion Intracellular calcium elevation can inhibit the cell viability and increase the levels of SOD and GSSG in HLEC to aggravate the intracellular oxidative damage.
