  • Composition comprising double stranded RNA that inhibits expression of NEU3 and method for treating cancer
    Patent number: 7795233
    Abstract: A pharmaceutical composition for treating cancer or diabetes which contains the following double-stranded RNA (A) or (B): (A) a double-stranded RNA having a sequence represented by SEQ ID NO:2, SEQ ID NO:4 or SEQ ID NO:8. (B) a double-stranded RNA which has a sequence of 20 to 30 nucleotides that is identical to a partial sequence of a gene encoding human plasma membrane-associated sialidase (NEU3) and contains the sequence represented by SEQ ID NO: 2, SEQ ID NO: 4, or SEQ ID NO: 8, and the double-stranded RNA inhibits the expression of a gene encoding human plasma membrane-associated sialidase (NEU3).
