4. 项目简介:
中国女性恶性肿瘤的发病率明显上升,乳腺癌位居首位。女性特发的常见肿瘤还有宫颈癌、卵巢癌等。遗传因素对肿瘤发生发展有重要影响。单核苷酸多态(SNPs)是最常见的遗传变异,非编码RNA是表观遗传学主要机制之一。另外,RNA干扰和基因编辑技术已被广泛用于探索基因功能和肿瘤的基因治疗。因此,本项目围绕着 SNP 和非编码 RNA 等遗传变异,研究它们与女性肿瘤发生发展的关系及作用机制并开展临床前研究,取得了创新性的系列研究成果。主要发现点包括:(1)发现了一系列与女性恶性肿瘤相关的遗传变异及其作用机制。如:EpCAM rs1126497 C/T多态和MKK4 -1304T>G多态与宫颈癌风险相关,前者还可能是乳腺癌的遗传修饰;hMLH1的-93A等位基因会影响卵巢癌易感性;FOXP3与乳腺癌的易感性相关;IL-21功能多态可能是乳腺癌预后的潜在生物标志;长非编码RNA Yiya可能与女性肿瘤相关。(2)发现了新的针对肿瘤治疗的RNA干扰和基因编辑技术。主要包括:阐明了siRNA的代谢途径,建立了创新性的高特异性siRNA设计策略;鉴定了对错配敏感的“核心”序列,增加了CRISPR-Cas9技术的靶向特异性。
上述研究结果连续发表多篇高水平论文,其中包括Hum Mutat、Molecular Therapy 和 FASEB Journal等国际权威期刊,引起了Nature Reviews Genetics(IF=40.3)和Nature Materials(IF=39.73)等国内外同行关注,获得授权专利1项;10 篇代表作总影响因子 44.6 分,SCI 总引用 162 次;研究成果进一步家加深了解遗传变异在肿瘤发生中的内在机制;提供个体易感性和临床预后参考指标,实现肿瘤个体化治疗原则,提高治愈率;缩小肿瘤发病高危人群范围,减少政府对肿瘤防治投入;可获得良好的社会和经济效益,将会对我国的经济建设产生不可估量的影响。
