个人简介

2017-至 今:中国科学院上海营养与健康研究院 研究员 2007-2016年:中国科学院上海生命科学研究院营养科学研究所 研究员 2005-2007年:美国宾州州立大学 生物系 助理研究教授 2002-2005年:美国哈佛大学医学院Beth Israel Deaconess医学中心 博士后 2001-2002年:美国明尼苏达州立大学 精神神经学系 博士后 1997-2001年:日本东京大学 神经生化学系 博士 1992-1995年:大连医科大学 病理生理学系 硕士 营养对于维持机体能量和糖脂代谢稳态至关重要,而营养稳态失衡导致的糖脂代谢紊乱是诱发肥胖、2型糖尿病和脂肪肝等代谢性疾病的重要驱动因素。本课题组长期致力于研究氨基酸的营养感应和对机体的代谢调控机制。前期工作通过利用一种必需氨基酸(亮氨酸)缺乏饮食处理的小鼠模型,发现亮氨酸缺乏导致小鼠体重下降和内脏脂肪显著减少及胰岛素敏感性增强的作用与机理。这些研究结果创新性地将氨基酸与能量和糖脂代谢调节联系在一起,阐释了氨基酸与能量、糖脂代谢之间的关联。但机体各代谢器官如何感应氨基酸改变以及通过哪些具体信号通路来调控能量与糖脂代谢稳态的作用仍不清楚。本课题组拟通过利用多种组织特异性基因敲除小鼠及细胞系体外模型,结合脑室定点注射、尾静脉注射、皮下脂肪组织定点注射腺病毒等手段开展相关研究。这些研究成果将深化人们对氨基酸感应和代谢调控分子机制的理解,阐明各代谢器官调控这些过程的关键信号分子网络,并将有助于发现防治代谢性疾病的新分子药物靶标。
