摘　　要：目的探究下调赖氨酸甲基转移酶2(lysine methyltransferase 2E,KMT2E)蛋白表达对登革Ⅱ型病毒(dengue virusⅡ,DENVⅡ)增殖的影响,初步分析KMT2E在DENVⅡ增殖过程中的调控作用。方法针对KMT2E的编码序列设计3条小干扰RNA(small interfering RNA,siRNA),转染293T细胞以筛选出下调KMT2E表达效率最高的siRNA,并用实时荧光定量分析DENVⅡ在KMT2E表达下调后的增殖情况。结果编号为1的siRNA(siKMT2E-1)有最高的下调KMT2E蛋白表达效率,转染293T细胞后能明显抑制DENVⅡ增殖。结论KMT2E可能在DENVⅡ增殖过程中发挥正调控作用。Objective To explore the effect of lysine methyltransferase 2E(KMT2E)knockdown on DENV virus Ⅱ(DENV Ⅱ)proliferation and preliminarily analyze the role of KMT2E in DENV Ⅱ proliferation.Method According to the coding sequence of the kmt2e gene,three siRNAs were designed.293T cells were transfected with these siRNAs to select the one with the highest efficiency in knockdown of KMT2E.RT-qPCR was used to analyze the proliferation of DENV Ⅱ after knockdown of KMT2E.Result The siRNA numbered as siKMT2E-1 possesses the highest knockdown efficiency of KMT2E protein,and can significantly inhibit DENV Ⅱ proliferation once transfected to 293T cells.Conclusion KMT2E may be plays a positive role in the proliferation of DENV Ⅱ.
