目的:研究p38丝裂原活化蛋白激酶（MAPK）基因沉默对大气细颗粒物（PM 2.5）染毒肝细胞（L02细胞）相关基因表达的影响。 方法:于2019年6至9月，根据GenBank提供的p38MAPK基因序列，设计合成3条干扰序列，退火后连接到PLVX-shRNA2-puro中，将重组慢病毒载体转染L02细胞。用实时荧光定量聚合酶链反应（PCR）和蛋白免疫印迹（Western blotting）法对p38MAPK基因沉默效果进行鉴定。用浓度为50 μg/ml的PM 2.5水溶物和10 μmol/L阳性对照Cr 6+分别染毒L02细胞、p38MAPK基因沉默细胞24 h，同时设立空白对照组。用荧光定量PCR检测癌基因（c-fos、c-myc、k-ras）、抑癌基因（p53）和凋亡基因（Casp...

Objective:To study the effect of p38 mitogen-activated protein kinase (MAPK) gene silencing on expression of apoptotic genes and oncogenes in hepatocytes treated with PM 2.5. Methods:From June to September 2019, according to the p38MAPK gene mRNA sequence provided by GenBank, three interfering sequences were designed and synthesized, ligated into PLVX-shRNA2-puro after annealing, and the recombinant lentiviral vector was transfected into L02 hepatocytes. The p38MAPK silencing cells were identified by real-time fluorescent quantitative PCR and...
