摘要 1.高氧气氛诱导培养的神经元细胞凋亡,包括PC12细胞和大鼠胚胎皮质、海马和基底前脑神经元,与DNA断裂和核固缩相关。2.中枢神经系统神经元对高氧气氛的敏感性如下:皮质>基底前脑>海马3。放线菌酮和放线菌素-D抑制细胞凋亡,表明其依赖于新的大分子合成。相反,培养的出生后CNS神经元对氧化应激具有抵抗力。4.神经生长因子(NGF)、成纤维细胞生长因子(FGF)和表皮生长因子(EGF)等神经营养因子可阻断高氧气氛诱导的细胞凋亡。
Abstract1. A high oxygen atmosphere induced apoptosis in cultured neuronal cells including PC12 cells and rat embryonic cortical, hippocampal, and basal forebrain neurons associated with DNA fragmentation and nuclear condensation.2. The sensitivity of CNS neurons to a high-oxygen atmosphere was the following order; cortex > basal forebrain > hippocampus.3. Cycloheximide and actinomycin-D inhibited the apoptosis, indicating that it depends on new macromolecular synthesis. In contrast, cultured postnatal CNS neurons were resistant to oxidative stress.4. Neurotrophic factors such as nerve growth factor (NGF), fibroblast growth factor (FGF), and epidermal growth factor (EGF) blocked the apoptosis induced by a high-oxygen atmosphere.
