Abstract:
Objective:To explore the specific cleavage activities of type 10-23 deoxyribozyme 10-23 DRz enzymes on HBV S and C RNA
in vitro.
Methods:The recombinant plasmids containing HBV S and C gene were constructed,respectively.The HBV S or C gene RNA was synthesized
in vitro using the linearized recombinant plasmid as template.The DRz-hbvs-1 and DRz-hbvc-1 targeting to cleave HBV S and C mRNA were designed and synthesized,respectively,and the cleavage activities of which on targeting RNA were observed
in vitro.
Results:The DRz-hbvs-1 and DRz-hbvc-1 could specifically and effectively cleave the targeting RNA,and the cleavage of which in nonDRz and ASODN control groups were not found.
Conclusions:The 10-23 DRz can specifically cleave the HBV S and C gene RNA in vitro.
