    袁海心,教授,博士生导师。2002年毕业于中国科学技术大学,获理学学士学位;2009年毕业于中国科学院上海生化细胞研究所,获生物化学与分子生物学博士学位;2009-2014年在美国加州大学圣迭戈分校做博士后,从事细胞生长与细胞自噬的调控机制研究。2014年11月受聘于复旦大学生物医学研究院,任青年研究员/PI;2019年12月晋升为研究员/PI。2021年10月加入重庆医科大学生命科学研究院新靶标与化学干预研究中心。

    袁海心教授关注细胞代谢与死亡调控机制的研究,已发表学术论文30余篇(总影响因子逾500),近年在Nature Commun、Cancer Res、Oncogene等知名期刊发表通讯作者论文多篇。获得国家自然科学基金面上项目(4项)、国家科技重大专项和国家重点研发计划等资金支持,并入选上海高校特聘教授(东方学者)和上海市人才发展资金等人才计划、重庆市留学人员回国创业创新支持计划(重点项目)以及重庆医科大学重大科技人才项目“揭榜挂帅”计划(A类)等重要人才计划支持。


    研究方向:细胞代谢与死亡调控机制

    (1)代谢紊乱是肿瘤及多种疾病发生的重要原因,本课题组致力于细胞生长与代谢机制的研究,运用生物化学、细胞生物学以及动物模型等实验手段,研究与肿瘤等疾病相关的信号转导通路、代谢酶的翻译后修饰(磷酸化、乙酰化和泛素化等)以及代谢酶突变等重要问题,期望揭示代谢异常与人类重大疾病尤其是肿瘤的关系。

    (2)铁死亡是近年来发现的一种新型细胞死亡方式,它由细胞内脂质过氧化物累积而导致,与细胞内的脂质代谢平衡密切相关;然而关于铁死亡的调控机制和生理功能仍有许多未知。本课题组利用高通量筛选的方法寻找并阐明铁死亡调控的关键基因和信号通路,并利用动物模型研究铁死亡与糖脂代谢异常相关疾病的关系,为疾病治疗提供新的策略。
