RESUMEN
Objective To construct the recombinant plasmid carrying shRNA to ATX and analyze the nucle- ic acid sequence for further searching new gene therapy method of tumor.Methods Two DNA sequences containing short hairpin structure were designed and synthesized.The complement form was obtained by annealing and inserted into vector Psilcncer2.1-U6 neo,and the recombinant plasmid was transformed into DH5a strain.Finally the plasmid identified by restriction enzyme was used for sequence analysis.Results The recombinant Psileneer2.1-U6 neo car- rying shRNA to ATX had been constructed and the aim sequence had been obtained.Conclusion The construction of the recombinant plasmid carrying shRNA to ATX lays the basis for the study of its inhibitive effect on tumor.
