摘要
This invention describes a relevant etiology of cancer and a novel anti-cancer therapeutic strategy, based on the discovery that a protein named serine protease inhibitor (SPIK/SPINK/PSTI) was up-regulated by hepatitis B and C virus infections consequently suppressing the cell apoptosis. Accordingly, this invention provides an inhibitor of SPIK and/or a technology of suppression of over-expression of SPIK in cells. The inhibitors include: 1) chemical compounds, which can inhibit SPIK transcripts, protein activity, and gene expression, 2) SPIK siRNA (RNAi gene silence or dsRNA of SPIK, 3) DNA anti-sense and anti-SPIK antibody. Further, this invention provides a method of using the inhibitor as an anti-cancer agent to re-instate cancer cell apoptosis (e.g., serine protease dependent cell apoptosis).
