ABSTRACT
To silence the expression of K-RASAsn12 in human pancreatic cancer cell line by vector-based RNAi(RNA interference) technique,two single-strand DNA sequences encoding mutant-specific shRNA (short haipin RNA) for K-RASAsn12 were synthesized and then inserted into pSilenCircle. The recombinant plasmid was called pSC-K-RASAsn12. According to the same method, pSC-GFP encoding shRNA for GFP was gained. Both recombinant plasmids were transfected into human pacreatic cancer cell line AsPC-1 and BxPC-3. The expression level of K-RASAsn12 was detected by semi-quantitative RT-PCR and Western blot. The result indicated that the recombinant plasmid edcoding mutant-specific shRNA for K-RASAsn12 can inhibit significantly the expression of K-RASAsn12 without affection of wild-type K-RAS(K-RASWT)in Human Pancreatic Cancer Cell Line.
