The effect of short hairpin RNA and DNAzyme gene therapy on latent membrane protein-1 expression in nasopharyngeal carcinoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the inhibitory effects of short hairpin RNA (pshLMP1) combined with DNAzyme or alone on latent membrane protein-1 (LMP1)expression in HNE1 cell lines.@*METHOD@#The pshLMP1 and DNAzymes were co-transfected with pEGFP-N1-1158 (a expression vector encoding LMP1 and EGFP fusion protein) into HNE1 cells, divided into 4 groups as positive control, RNA interference, combining and DNAzyme groups. The green fluorescence were analyzed and then the mRNA and protein of LMP1 gene were detected.@*RESULT@#The HNE1 cells expressing green fluorescence in combining group were significantly less than that in RNA interference group (P < 0.01); The inhibition efficiency of green fluorescence in combining group were 86. 31% Wp 88.88% ,which were higher than that in RNA interference group with 75.15%. The detection of LMP1 mRNA and proteins showed that combining group had a higher inhibition ability.@*CONCLUSION@#Combining gene therapy with pshLMP1 and DNAzyme is superior to pshLMP1 alone to inhibit LMP1 gene expression.
