主要研究方向与成果:

1iPSC诱导分化的类器官模型在神经系统疾病重塑和致病机制研究中的应用。

先天性巨结肠症(HSCR)是一种复杂的肠神经系统发育缺陷的遗传病。(1)我们通过全基因组测序筛选首次报道了BACE2功能缺失突变为HSCR的新致病因素,并利用病人iPSC诱导分化的肠神经嵴细胞(ENCC)模型阐明了BACE2介导的APP蛋白切割失衡是诱发肠神经细胞凋亡的新致病机制Gastroenterology, 2018; Featured comments by Heuckeroth TO Gastroenterology, 2018。该研究发现为BACE2功能缺失HSCR病人的临床诊断和治疗提供了新靶点。(2)基于iPSC诱导分化的ENCC及结直肠类器官模型,建立了可在体内外模拟ENCC分化,成熟及其支配结肠类器官蠕动等神经生理过程的3D模型Gastroenterology, 2019。该研究发现为我们在体内外验证HSCR相关的致病基因,重塑HSCR病人相关的病理特征,以及致病机制研究和药物筛选等转化工作提供了一个近乎人体微环境的3D模型。(3)基于iPSC诱导分化的脑类器官模型,阐明了BACE2介导的APP蛋白切割失衡是HSCR-AD共同的致病机制Cell Death Discovery, 2022Cell and Bioscience, 2021。该研究发现证明了肠脑神经系统疾病在发病机制和病理特征等方面存在非常高的相似性,为肠脑关联神经系统疾病的诊断和治疗等提供了新思路

 

2Hippo-YAP信号通路在肿瘤发生发展及肿瘤微环境重塑中的作用及分子机制研究。

YAP (Yes-Associated Protein) Hippo信号通路的下游效应因子。作为一个转录共调节因子,该蛋白过表达或者激活参与到肿瘤发生发展、转移、治疗耐药以及肿瘤微环境重塑等多个过程中。(1)上皮细胞连环蛋白(αE-catenin)缺失可诱导肿瘤发生,我们研究发现αE-catenin可通过抑制Integrinβ4-SRC-YAP信号通路的激活,从而发挥其抑癌作用。在该信号通路终端,由激酶SRC介导的YAP酪氨酸位点磷酸化才是αE-catenin缺失诱导肿瘤发生的真正原因Genes and Development, 2016。该研究成果阐明了αE-catenin缺失诱导肿瘤发生的新机制,为该类肿瘤靶向治疗提供了新思路。该研究成果多次被NatureCellCell Stem Cell等顶级杂志进行引用和论述,并两次被世界学术组织F1000正面评论并列为推荐阅读论文。(2)进一步研究还发现SRC激活介导的YAP酪氨酸位点修饰诱导了YAP/TEAD与转录因子KLF5TFAP2A等转录复合体的形成以及下游靶基因的转录,并促进了三阴乳腺癌的干性和转移潜能Cellular and Molecular Life Sciences, 2023,以及HER2+乳腺癌对曲妥珠单抗治疗的耐药Drug Resistance Updates, 2024。(3)研究还证实YAPRNA结合蛋白复合体LIN28/MSI2诱导三阴乳腺癌肿瘤干性和转移的关键效应分子,因此靶向YAP依赖的转录输出有望成为治疗该类三阴乳腺癌的新靶点Oncogene, 2022
