    • Activation of the Ki-ras proto-oncogene is common in colon carcinogenesis. Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit carcinogen-induced colon carcinogenesis, decrease the frequency of Ki-ras mutations in the azoxymethane-treated rat model, and induce apoptosis in a variety of cell types. Sulindac, as well as other non-steroidal anti-inflammatory agents, are provided in combination with DFMO the prevention and/or treatment of cancers characterized by the expression of an activated Ki-ras. Provided with the present invention are pharmaceutically acceptable compositions that include a non-steroidal anti-inflammatory agent, sulindac, together with an effective amount of difluoromethylornithine.
    • Ki-ras原癌基因的激活在结肠癌发生中是常见的。 非甾体抗炎药(NSAIDs)抑制致癌物诱导的结肠癌发生,降低氧化氮甲烷治疗大鼠模型中Ki-ras突变的频率,并诱导各种细胞类型的凋亡。 与DFMO组合提供舒林酸以及其它非甾体抗炎药,预防和/或治疗以活化的Ki-ras表达为特征的癌症。 本发明提供了药学上可接受的组合物,其包括非甾体抗炎药,舒林酸,以及有效量的二氟甲基鸟氨酸。
