项目摘要
In this study, the cell deterioration mechanism by phospholipid hydroperoxides was examined first, and the effect of some food constituents for the deterioration was shown. PC12 cell line was initially derived from rat adrenal phenocromocytoma. PV12 cells differentiate into sympathetic neuron-like phenotypes in response to the nerve growth factor. PC 12 cell were cultured in collagen-coated dishes in RPMI-1640 medium supplemented with 10% heat-inactivated horse serum, 5% heat-inactivated fetal bovine serum and penicillin/streptomycin in the presence of adequate amounts of phospholipid hydroperoxides. Phospholipid hydroperoxides oxidized cell membrane and next deteriorated tubulin by the interaction. The effects on antioxidant enzyme activities and the oxidative damage of DNA were observed also. The interaction between phospholipid hydroperoxides and tubulin introduced the decrease of microtubule assembly, and the functions of microtubule were deteriorated. Dosed and derived reactive oxygen species influenced antioxidant enzyme activities and DNA. Therefore, the recovery effects by antioxidants from foodstuffs were examined. Antioxidants made functions tubulin and antioxidant enzyme to recover. The facts indicate antioxidants effective on the ageing by reactive oxygen species.
在这项研究中,首先检查了磷脂氢过氧化物的细胞恶化机制,并显示了某些食物成分对恶化的影响。 PC12细胞系最初源自大鼠肾上腺稳态细胞瘤。 PV12细胞响应神经生长因子而分化为交感神经元样表型。在补充10%热灭活马血清的RPMI-1640培养基中,将PC 12细胞培养在胶原蛋白涂层的培养皿中,在足够量的磷脂液过氧化物的情况下,在足够量的磷脂含量的情况下,含有10%的热灭活马血清,5%热灭活的胎牛血清和青霉素/链霉素。通过相互作用,磷脂氢过氧化物氧化细胞膜,然后通过相互作用恶化小管蛋白。还观察到对抗氧化酶活性和DNA的氧化损伤的影响。磷脂氢过氧化物和微管蛋白之间的相互作用引入了微管组件的降低,并且微管的功能降低了。剂量和衍生的活性氧影响抗氧化酶活性和DNA。因此,检查了抗氧化剂从食物中的恢复作用。抗氧化剂使功能小管蛋白和抗氧化剂酶恢复。事实表明,活性氧对衰老有效的抗氧化剂。
