Abstract
The present invention relates to a composition for treating or sensitizing interferon beta resistant cancer disease comprising cFLIP siRNA, and, more specifically, to a pharmaceutical composition for treating interferon beta resistant cancer disease, comprising, as an active ingredient: (a) an siRNA complementarily binding to mRNA of a cFLIP gene; and (b) a human interferon beta variant which comprises glycine-asparagine-isoleucine-treonine-valine sequence (GNITV) at C-terminus in a human natural interferon beta amino acid sequence shown in SEQ ID NO: 1, or has replaced the 27arginine amino acid with threonine or serine, and to a composition for sensitizing interferon beta resistant cancer cells comprising cFLIP siRNA as an active ingredient. The composition of the present invention can be effectively used to develop an anticancer agent or anticancer adjuvant having a new mechanism to promote apoptosis and effectively sensitize cells for treatment, by lowering an expression level of cFLIP proteins in a cancer showing resistance to interferon beta or a cancer becoming resistant to interferon beta.
