  • Patent number: 9856480
    Abstract: The invention provides DNAzymes which are capable to silence the expression of EGFR at allele-specific level. These allele-specific DNAzymes against EGFR T790M mutation will knockdown the expression of EGFR T790M mRNA while keeping EGFR wild-type mRNA intact. Hence, these allele-specific DNAzymes against EGFR T790M mutation may overcome T790M-derived TKI resistance accompanied with lower unwanted side effects on normal cells in lung cancer patients.
