个人简介

中科院上海生物化学与细胞生物学研究所博士毕业。曾在美国贝勒医学院和美国哥伦比亚大学从事博士后研究。2009年起任南京大学副教授，组建肿瘤表观遗传实验室。目前主要研究方向是利用基因组改造小鼠和临床样本，揭示肿瘤耐药和转移的表观遗传分子机制，建立新的分子药物靶点以及相应的临床前验证。至今共主持3项国家基金委面上项目，1项江苏省面上项目，1项教育部博士点新进教师类项目并参与2项973计划、1项国家支撑计划和1项国家重点研发计划和课题。共发表38篇论文，2篇综述和1篇论著，引用次数1100多次。肿瘤复发和转移一直威胁着肿瘤病患的生命。因此对于这两个临床现象的深入认识将会对于肿瘤病患的生存和死亡率带来实际的改变。由于肿瘤组织存在非常显著的异质性，而不同的肿瘤细胞亚群在所处不同微环境或药物选择压力的情况下，筛选出最为适应环境的不同肿瘤亚群。治疗过程中，即使少量的肿瘤干性细胞残留于病患体内，它们仍可以重建整个肿瘤，从而导致肿瘤的复发和转移。现有的实验数据显示这些肿瘤干性细胞亚群具有上皮向间充质转变（EMT）和表达乙醛脱氢酶系等共同特性，但是还存在着很多未解之谜。譬如，肿瘤细胞干性维持的分子机制以及药物靶点的验证。以下是我们实验室的主要研究方向： 1. 耐药和转移的分子靶点发现和鉴定：我们利用小鼠模型及组学的手段分析鉴定耐药和转移的驱动基因。我们发现了组蛋白 H3K27甲基转移酶EZH2 表达量可以预测非小细胞肺癌的耐药性和无疾病进展生存。同时，我们在前列腺癌和膀胱癌中也发现重要参与耐药复发的非编码RNA，它们通过调控肿瘤干细胞群体的干性增加肿瘤的恶性程度。 2. 肿瘤微环境对于肿瘤细胞的耐药和转移的调控机制：肿瘤的微环境是一个与肿瘤细胞相互作用的重要场所，起到了维持肿瘤恶性的重要作用。我们实验证明在肌肉侵润型的膀胱癌组织中，肿瘤相关成纤维细胞（CAF）通过旁分泌TGFβ1促进膀胱癌细胞中 lncRNA-ZEB2NAT的表达，提高ZEB2蛋白水平，进而产生EMT。肿瘤微环境中CAF对于实体瘤细胞的调控网络将是一个重要的研究对象。 3. 新型耐药和转移的小鼠模型构建及其在小分子药物的前期临床验证：我们利用小鼠的优势，构建并鉴定了多种重现临床前列腺癌和膀胱癌的小鼠模型。同时我们利用天然产物和小分子单体鉴定了它们对于肿瘤的耐药及转移的有效性。其中包括Zyflamend、和厚朴酚和生育三烯酚等体内外的作用效果和机理。通过这些研究，将完成针对耐药和转移的小分子抑制剂的开发。论著和综述: 1.
