Two genes are considered synthetic lethal if mutation of either alone allows cell viability, whereas simultaneous mutation leads to cell death. A synthetic lethal screen unveiled the dependency of Wnt/beta-catenin-addicted colorectal cancer cells on vascular endothelial growth factor receptor-1 kinase activity and suggested a novel therapeutic approach for this malignancy. (Clin Cancer Res 2009;15(24):7453-5).
如果单独一个基因发生突变时细胞仍可存活,而两个基因同时发生突变则导致细胞死亡,那么这两个基因被认为是合成致死基因。一项合成致死筛选揭示了对Wnt/β-连环蛋白成瘾的结肠癌细胞对血管内皮生长因子受体-1激酶活性的依赖性,并提示了针对这种恶性肿瘤的一种新的治疗方法。(《临床癌症研究》2009年;15(24):7453 - 7455)
