研究概述
Research Description
伴随着人口的老龄化，癌症和神经退行性疾病对人类威胁最大的两种疾病。虽然癌症和神经退行性疾病是两种对立的疾病，一个是细胞的过度生长，一个是细胞病例死亡，但是这两种疾病的引发涉及到许多共同信号通路。我们实验室主要应用果蝇模型探索细胞生长和神经退行性死亡的基本原理，最终帮助人类攻克这些疾病。
1. 雷帕霉素靶蛋白（TOR）通过形成两个结构和功能截然不同的复合物TORC1和TORC2在细胞，组织器官以及整个生物体的生长中起着中心调控的作用。本实验室目前针对TORC1和TORC2的上下游机制，以及在衰老中的调控机制进行研究，目标是建立TOR的信号调控网络，包括TOR对营养，内源激素，生长因子，以及各种外界压力的应答及相互作用。
2. 在多细胞生物体中，组织的建立以及代谢是通过细胞生长及死亡共同完成的。全面理解神经退化疾病机理不仅利于治疗这类疾病，也为治疗生长相关的疾病比如癌症提供有效的手段。我们的实验室计划用果蝇模型研究神经退化疾病。我们实验室建立了帕金森氏综合症等几种神经退化疾病的果蝇模型，通过遗传学的手段筛选帕金森氏综合症的修饰基因，研究线粒体自噬的分子机理，以及致病基因Pink1, Parkin, DJ-1 and LRRK的相互作用，并且在这些神经退化疾病模型中测试药物的效果。
3. 用果蝇模型研究视觉的信号传导通路和视网膜退行性疾病的分子机理，用遗传学和药理学探索视网膜退行性疾病的治疗手段。
Cancer and Neurodegenerative diseases are two most clinically problematic classes of disease impacting the world's aging populations.Although there are apparently opposite phenotypes between cancer cells and degenerated neurons, common molecular mechanisms might be involved in dysregulated cancer cell growth and the progression of neurodegenerative disease.Our laboratory is using Drosophila system to study the basic molecular mechanisms and crosstalk of cell growth and neurodegenerative cell death.The ultimate goal of research is to help cure both diseases. Specifically, research will focus on the following areas:
1. Organisms are able to respond appropriately to nutrient flux to increase their size and cell number so called ‘growth’.Problems in growth process lead to lots of severe diseases, for example, cancer can be considered overgrowth of cells.The Target of Rapamycin (TOR) has central roles in controlling growth of cells, tissues and organisms by generation of TOR complex 1 (TORC1) and TOR complex 2 (TORC2).We are using genetic system to learn the basic mechanisms of TORC1 in response of stress, upstream signals and downstream targets of TORC2 in the cell growth pathway, and the mechanisms of TOR’s effect on aging.The ultimate goal of our lab is to establish an entire network of TOR in response of nutrition, growth factors, hormones and stress.
2. In metazoans, the coupling of cell growth and cell death together controls the tissue homeostasis.Understanding neurodegenerative diseases not only benefits cell death related diseases, but also arises the treatment option for growth related diseases such as cancer.In our lab, we are usingDrosophila model to study the pathogenesis of neurodegenerative diseases especially Parkinson's disease (PD).We are trying to identify the upstream signal of Pink1 and downstream targets of Parkin in mitophagy pathway; understand the genetic interaction between major PD associated genes, Pink1, Parkin, DJ-1 and LRRK; screen for suppressors of PD animals.In the end, the therapies or drug targets of PD might be presented.
3. Retinal degeneration and vision loss is one of the major health problems, afflicting ~300 millions of people worldwide.However, in most cases, the underlying mechanisms responsible for retinal degenerations are still poorly understood, hence have very few effective treatments.The goals of our research are to exploit Drosophila as a model organism for characterizing the mechanisms underlying phototransduction and Retinal Degenerations, and to explore strategies for suppressing these types of neuronal cell death.
