摘要:
为了探讨泛素(ubiquitin,简称Ub)对TLR4/NF-κB信号通路中关键分子表达的影响,通过脂质体将短发夹RNA(shRNA)质粒转染猪小肠上皮细胞,使其泛素基因沉默,于转染后6、12、24、48 h收集细胞及其上清。应用荧光定量PCR检测细胞内TLR4/NF-κB信号通路中关键分子TLR4、NF-κB、MyD88、IκB-α的mRNA表达水平,应用酶联免疫吸附测定法(ELISA)检测NF-κB、IκB-α及炎性因子TNF-α、IL-1含量的变化。结果显示,shRNA质粒有效地抑制了泛素基因的表达,转染shRNA质粒后,TLR4/NF-κB信号通路中TLR4、NF-κB、MyD88和IκB-α的mRNA表达量及NF-κB、IκB-α、TNF-α和IL-1含量均普遍呈下降的趋势,说明泛素在炎性因子的释放中起着至关重要的作用,泛素基因的沉默能够抑制该通路的活化。
