1乏氧条件下X射线诱导神经胶质母细胞瘤T98G细胞的旁效应显示文摘采用条件培养基和共培养处理方式,应用微核形成试验研究人神经胶质母细胞瘤T98G细胞,在乏氧条件下经X射线诱导的旁效应及其发生机制。研究发现,乏氧条件下,X射线诱导未照射组细胞的微核率与相应的照射剂量之间存在显著的正相关关系;条件培养基方式下自由基抑制剂二甲基亚砜(Dimethyl sulfoxide,DMSO)可显著降低未照射组细胞的微核率;条件培养基处理乏氧或有氧的T98G细胞,有氧条件培养基处理乏氧细胞引起的旁效应微核率比其它各组均要显著,而诱导型一氧化氮合酶(Inducible nitric oxide syntheses,iNOS)特异性抑制剂氨基胍(Aminoguanidine,AG)可抑制条件培养基所诱导的旁效应。推测乏氧条件下,受辐射的T98G细胞所诱导的旁效应与受照射细胞产生的自由基有关,尤其是活性氧自由基和一氧化氮。张江虹 Kevin M Prise 金一尊 邵春林 2008辐射研究与辐射工艺学报2008,26,2:3
2一氧化氮在亚细胞结构精确照射诱导旁效应中的作用显示文摘研究了肿瘤细胞的亚结构在荷能离子照射下所诱导的旁效应及其信号分子。以氦离子微束装置所产生的精确数量离子定位照射神经胶质瘤细胞T98G细胞核或细胞质,检测细胞染色体损伤和胞内一氧化氮(Nitric Oxide,NO)自由基的产额,探索NO清除剂对它们的影响,并以(Diethylamine nitric oxide,DEANO)研究NO的细胞效应。结果表明,无论是细胞核照射还是细胞质照射,只要1个细胞受到1个离子的照射,就可通过损伤的级联放大形成辐射旁效应,引起周围数十个细胞的损伤。对比核、质照射的生物效应,细胞核照射比细胞质照射具有更加显著的直接作用,但这两种照射所诱导的旁效应程度却相当。而NO自由基清除剂c-PTIO(2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide)可抑制旁效应的产生。NO分子探针DAF-FM(4-amino-5-methylamino-2',7'-difluorofluorescein diacetate)原位检测表明,即使只有1%的细胞核或细胞质受到单离子照射,具有NO阴性表达的细胞百分数增加了30%,使NO引起的细胞荧光密度增加15%。DEANO实验表明,NO可引起细胞微核的产生。因此,NO是亚细胞结构照射引起旁效应的一个重要信号因子。邵春林 FOLKARD Melvyn PRISE Kevin M 2007辐射研究与辐射工艺学报2007,25,2:2
