    • 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).
    • 本发明描述了癌症的相关病因和新型抗癌治疗策略,基于以下发现:称为丝氨酸蛋白酶抑制剂(SPIK / SPINK / PSTI)的蛋白质被乙型和丙型肝炎病毒感染上调,从而抑制细胞 凋亡。 因此,本发明提供了SPIK抑制剂和/或抑制细胞中SPIK过度表达的技术。 抑制剂包括:1)可抑制SPIK转录物,蛋白质活性和基因表达的化合物,2)SPIK siRNA(SPIK的RNAi基因沉默或dsRNA,3)DNA反义和抗SPIK抗体。 此外,本发明提供了使用该抑制剂作为抗癌剂来重新制备癌细胞凋亡(如丝氨酸蛋白酶依赖性细胞凋亡)的方法。
