摘要
目的:观察不同氧浓度环境下不同时间处理对大鼠大脑皮层细胞表达IL-1β、IL-6和TNF-α mRNA的影响。方法:原代培养新生SD大鼠大脑皮层细胞,设1%、4%两个低氧浓度和3、6 h两个低氧处理时间,处理结束后收集各组细胞,采用实时荧光定量PCR(RT-QPCR)方法检测各组细胞表达IL-1β、IL-6和TNF-αmRNA情况。结果:与相应的常氧对照组相比,1%和4%氧浓度环境处理细胞3 h和6 h时,IL-1β和TNF-αmRNA表达量均无明显变化(P>0.05);处理细胞3 h时,IL-6 mRNA表达量均无明显变化(P>0.05),但有上升的趋势,处理细胞6 h时IL-6 mRNA表达量均显著升高(P<0.05)。结论:1%和4%氧浓度环境虽均对大脑皮层细胞表达IL-1β和TNF-α mRNA无影响,但可诱导细胞表达IL-6 mRNA,且具有时间依赖性。
