    • The present invention relates to a RUNX3 gene showing anti-tumor activity which is essentially involved in TGF-β dependent-programmed cell death (apoptosis) and use thereof. In addition, the present invention finds that the RUNX3 gene expression is suppressed in the various gastric cancer and lung cancer cell lines. The suppression of the RUNX3 gene expression is due to hyper-methylation of CpG island located around RUNX3 exon (1). The RUNX3 gene and its gene product of the present invention can be used effectively for the development of anti-cancer agents. CpG island around RUNX3 exon (1) could also be used not only for the development of anti-cancer agents which regulate the abnormal DNA methylation and there by induce RUNX3 expression but also for the development of methods for cancer diagnosis by measuring the abnormal DNA methylation.
    • 本发明涉及显示抗肿瘤活性的RUNX3基因,其基本上参与TGF-β依赖性程序性细胞死亡(细胞凋亡)及其用途。 此外,本发明发现在各种胃癌和肺癌细胞系中RUNX3基因的表达被抑制。 RUNX3基因表达的抑制是由于位于RUNX3外显子周围的CpG岛的超甲基化(1)。 本发明的RUNX3基因及其基因产物可以有效地用于抗癌剂的开发。 RUNX3外显子(1)周围的CpG岛也不仅可用于开发调节异常DNA甲基化的抗癌剂,还可以通过诱导RUNX3表达,也可用于通过测定异常DNA甲基化来开发癌症诊断方法 。
