【摘要】：目的:探讨正常组与人工模拟寒环境组大鼠肺组织蛋白组学差异表达及质谱分析。方法:选取20只SD大鼠随机分为正常对照组与寒环境组,每组10只。寒环境组模型复制使用人工气候箱:(T)=(6±2)℃,每天刺激4 h(其余时间为正常组温湿度);正常组(T)=(21±2)℃,每天持续24 h。造模7 d后,两组大鼠于麻醉前12 h禁食、禁水,称量体重。麻醉后开胸取出左肺组织10 mg/只,每组取3个样本进行样品蛋白质制备、双向电泳实验、图像分析、质谱检测。结果:对两组差异蛋白图谱进行蛋白质组学分析,鉴定出9个蛋白在两组之间差异表达,寒环境组与正常对照组比较,其中4个表达上调、5个表达下调。结论:通过蛋白质组学分析,鉴定出的蛋白与外寒环境有相关性。
[Abstract]:Aim: to investigate the differential expression of proteomics and mass spectrometry in lung tissue between the normal group and the artificial cold environment group. Methods: twenty SD rats were randomly divided into normal control group and cold environment group with 10 rats in each group. The model of cold environment group was duplicated with artificial climate box: (T) = (6 卤2) 鈩，
