Research of 10-23 DNAZyme inhibit the expression of eIF4E genes / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the possibility of 10-23DNAzyme becoming a new gene therapy for laryngeal carcinoma treatment at the cell level.@*METHOD@#Thiosthorothioate 10-23DNAzyme specific to eIF4E gene mRNA 1059 was designed and synthesized, and its inhibition effects on the expression of eIF4E gene in Hep-2 cells were observed.@*RESULT@#The expression of eIF4E gene was remarkable depressed after Hep-2 cells was transfected by DNAzyme. The level of inhibiting eIF4E in hep-2 cells transfected by DNAzyme was lower than that by only lipofectamine 2000 transfected and Hep-2.@*CONCLUSION@#The expression of eIF4E gene in Hep-2 cells 10-23DNAzyme can be highly blocked. It is a specific and effective gene therapeutic means.
