摘要
Ras相关区域家族1A(RASSF1A)是从3p21.3区域克隆出来的新型候选抑癌基因。启动子区域CpG岛的异常甲基化可以导致RASSF1A失活,对包括前列腺癌在内多种实体瘤的发生、发展中起着重要作用。对大量临床标本中RASSF1A基因异常甲基化及其与相应病例临床特点之间的关系分析表明,RASSF1A甲基化检测有望成为前列腺癌早期诊断和预后判断的重要辅助手段,而丰富的实验研究则提示甲基化抑制剂有望成为前列腺癌治疗的新手段。
RASSF1A gene cloned from 3p21.3 region is a novel candidate tumor suppressor gene. The aberrant methylation of CpG lands in the promoter region is the major inactivation mechanism of RASSF1A, and is significantly involved in the genesis and development of multiple solid tumors including prostate cancer. The methylation status examination of RASSF1A could serve as an important technique for the early diagnosis of prostate cancer, while methylation inhibitor is likely to become a novel therapeutic agent.
