肿瘤分子细胞生物学。本实验室研究的方向主要包括细胞周期调控,癌基因和抑癌基因以及细胞程序性死亡在癌症发生中的作用。肿瘤已经成为中国第一死亡杀手,在全世界也是仅次于心血管疾病的第二死亡杀手。我们从位于细胞膜上的细胞感知生长因子和肿瘤坏死因子的受体开始,从基因和蛋白的水平上研究这些因子结合受体后,如何由外向内从细胞膜到细胞质及细胞核传递细胞生长和死亡信号;信号蛋白怎样和周期蛋白和周期蛋白依赖性激酶(cyclins and CDKs)组成的细胞周期调控分子系统对话;以及Rb和p53等抑癌基因通过阻断细胞周期和诱导肿瘤细胞凋亡,从而抑制癌细胞生长的机理。目前阶段,本实验室的工作主要集中在细胞程序性死亡或细胞凋亡(Apoptosis or programmed cell death)的机制及在肿瘤发生中的作用。细胞程序性死亡主要有两种途径。一条途径通过位于细胞膜上的死亡受体(肿瘤坏死因子受体,TNFR)及相关蛋白诱导。此途径通过激活TRADD,FADD,RIP等蛋白分子最终导致Caspase-8和 Caspase-3, 6, 7的活化而引起细胞的凋亡。TNFR信号通路同时激活转录因子NF-κB。NF-κB转录一系列细胞保护性基因而抵抗和平衡由Caspases引起的细胞凋亡。许多肿瘤细胞中由于突变NF-κB活性而大大增强,使得肿瘤细胞不再响应细胞凋亡信号。细胞程序性死亡的另一条途径通过Bcl-2蛋白家族诱导。抑癌基因p53通过转录活化某些Bcl-2家族成员像Noxa, Puma等而引起肿瘤细胞凋亡,抑制癌细胞生长。在大多数类型的肿瘤细胞中p53基因发生了突变。细胞失去了重要的抑癌基因p53的保护,从而导致肿瘤细胞逃脱了细胞程序性死亡的机制,使癌细胞获得了抵抗放疗和化疗药物杀伤的能力,转移并最终发生形成肿瘤。研究细胞程序性死亡的机制及在肿瘤细胞中的变化,将对了解肿瘤的发生机理和肿瘤的治疗具有重要意义。利用小分子化合物和多肽特异地激活肿瘤细胞中的细胞凋亡分子系统,已成为未来肿瘤治疗中非常有前景的靶向治疗方法,也是近年来国际上众多研究机构和制药公司激烈竞争的领域。
Our Laboratory is interested in understanding the molecular basis of DNA damage stress induced signal transduction in normal and cancer cells. In particular, we are interested in studying DNA damage induced apoptosis regulation and its role in tumorigenesis. Evasion from apoptosis is a hallmark of cancer. We concentrate our efforts on the Bcl-2 family proteins. Bcl-2 family proteins are central mediators of apoptosis. We are trying to understand how growth factor signaling and the tumor suppressor p53 regulate the activities of the Bcl-2 family proteins. We are utilizing a variety of biochemical, cell biological and RNAi-based approaches to identify new Bcl-2 family interacting proteins and characterizing how these proteins contribute to the regulation of cell death and/or cell survival. We are also determining the mechanism by which cell signaling regulates the gene expression and protein degradation of some members of the Bcl-2 family proteins.
