1 以雄蕊为对象的植物器官形成调控机制
2 植物发育事件相关基因表达在染色质水平调控
植物器官形成主要指来自顶端分生组织的一团未分化细胞如何形成具有特定形态与功能的三维结构,是植物发育中的一个重要过程。我们利用雄蕊为对象,从分析导致黄瓜雌花雄蕊发育停滞的分子机制、和发育早期不同阶段的水稻雄蕊基于表达谱两个角度入手,尝试解析雄蕊早期发育这一复杂的多细胞结构形态建成过程中关键的发育事件及其在分子水平的调控机制。这将不仅帮助我们了解雄蕊形成的机制,还可以帮助我们了解多细胞结构形态建成过程中的一些基本规律。
在我们前期的工作中,发现基因表达的染色质水平调控在植物发育事件中具有重要的作用。因此,我们面前利用拟南芥根表皮细胞分化过程中模式形成这一发育事件,探讨发育相关基因表达在染色质水平的调控机制,并希望利用在此研究中所积累的经验,帮助我们理解雄蕊早期发育的调控机制。

本实验室主要兴趣在于:
1.多价DNA疫苗的分子机理。
2.基因治疗的机制研究。
3.植物反应器的研究。
结核病是一种人畜共患病,严重威胁着人类的健康。传统的BCG疫苗的保护效率不一致。DNA疫苗可诱导体液和细胞免疫应答,而结核杆菌和布氏杆菌都是胞内寄生菌,DNA疫苗是未来非常具有开发前景的新型疫苗。实验室通过动物实验筛选优良的免疫主导性抗原,并通过DNA免疫的手段测定其保护效率及在动物保护中的作用机制。目前为止,建立了一套可靠的核酸疫苗免疫、检测评价体系,比较了各种多价不同组合及其分别与不同佐剂保或包裹剂混合免疫的保护效力,探讨了多种提高疫苗效力和持续期的策略和可行方法,并研究了各种方法在激发机体免疫机制上的差异和途径。
除了探讨DNA疫苗在预防方面的作用,我们通过DNA疫苗结合传统化学药物的方法对受感染的小鼠及牛进行基因治疗,进而探讨在感染后,DNA疫苗对机体内免疫反应类型的改变状况。
为进一步推进疫苗的实用性,我们构建了马铃薯来源的植物疫苗,动物可口服该疫苗而无须打针。通过动物实验,植物疫苗在小鼠体内诱导了体液免疫(尤其是粘膜免疫应答)和细胞应答反应。

科研领域描述
本实验室主要兴趣在于:
1. 生物的胁迫响应,包括衰老和休眠现象的分子机制 (Stress responses of living organisms: including the molecular mechanism of aging and dormancy)
2. 生物体内蛋白质-蛋白质相互作用的发生情况、机制、及生物学意义 (Mechanism and biological significance of protein-protein interactions)
任何生命形式都不可避免地要经历像高温、极端pH值、活性氧等有毒物质的存在等胁迫条件。在这样的条件下,生物体内的大分子,如DNA、RNA、蛋白质等由非共价弱相互作用维持的空间结构都将受到影响。这其中可能以蛋白质分子受到的威胁最大,蛋白质分子的去折叠往往会导致聚集的发生,而这将意味着蛋白质分子功能的丧失。过去的研究表明,各种生物的基因组都编码了一类被称为分子伴侣(或热休克蛋白、或胁迫蛋白等)的蛋白质分子。这些蛋白质的角色就是保护生物体内那些容易发生去折叠和聚集的蛋白质。这些“保镖”蛋白质,参与了对体内其它蛋白质分子的“生、老、病、死”等过程。我们关注的一些问题包括:胁迫蛋白质是如何在生物体内发挥其功能的?胁迫蛋白质分子的结构如何对胁迫条件发生瞬时响应而导致生物学活性顺时性提高的?部分生命个体以休眠方式应对极端胁迫条件的分子机制是什么?与此相关的衰老现象和休眠现象的分子机制是什么?等等。
蛋白质在生物体内发挥作用是通过与其它分子发生相互作用而完成的。大量的蛋白质分子自身或相互之间也发生着大量的相互作用。自身的相互作用,形成同源寡聚体,不同蛋白质分子之间的相互作用即形成异源寡聚体。尽管过去的体外或体内研究已经揭示了大量特异的蛋白质之间的相互作用,但大量发生于生物体内的动态的或弱的相互作用目前还难以鉴定和深入研究。我们关注的一些问题包括:很多通过体外研究被鉴定为以单亚基形式存在的蛋白质,在体内是否能够形成同源寡聚体?能够在活细胞条件下鉴定出与特异蛋白质发生相互作用的蛋白质?这样的以同源或异源寡聚形式发生的蛋白质-蛋白质相互作用如何完成特定的生物学功能?等等。

2.拟南芥野生居群的遗传多样性及分子适应性的研究
3.植物基因家族的功能和进化研究
研究对编码CHS、水稻胰蛋白酶抑制剂等基因家族的分子进化,发现多数植物的CHS基因可被分为两类,一类进化速率较慢,另一类进化速率较快且受到正选择的作用。CHS基因在裸子植物中的拷贝数较少,而在被子植物中拷贝数变化很大。水稻中Bowman-Birk型胰蛋白酶抑制剂(RBBI)10个成员的系统树及编码基因的5’和3’非编码区的序列分析发现有两个结构域受到了正向选择。对长城两侧的六种植物的居群遗传分化进行了分析,发现两侧的植物亚居群发生了显著的遗传分化,证明了长城在一定程度上阻断了两侧植物的基因流,或因其两侧的环境的微小差异造成了植物居群的变异。收集了全国约10个省份的30多个野生拟南芥居群,对其遗传多样性及分子系统树的研究表明,有一些居群可能很早就分布于中国,并在中国迅速扩张;对不同居群在逆境下的表达谱分析则发现明显的差异,进一步深入的研究正在进行中。

主要研究方向:
1.拟南芥中乙烯信号转导及植物激素间相互作用的分子机制
2.植物衰老的激素调控机理
3.小RNA分子和RNA降解的机理研究
4.植物激素的功能基因组和蛋白质组学研究
本研究组主要课题是研究植物激素乙烯信号转导的分子机制,以及在植物发育、衰老和胁迫反应中乙烯与其它激素和信号途径的相互作用。我们利用拟南芥作为模式系统,研究乙烯在生长发育过程中信号转导的分子机制,发现了EIN3/EIL1转录因子在乙烯信号途径中的关键作用;阐明了EIN3/EIL蛋白的调控机理,建立了乙烯反应中由泛素/蛋白酶体介导的蛋白降解模型。另外,发现了一个外切核酸酶EIN5在乙烯反应途径中的重要调节作用,揭示了EIN5的作用是通过促进相关基因的mRNA降解来拮抗EIN3蛋白降解,从而建立了乙烯反应中小RNA分子介导的RNA降解模型。同时,我们还发现乙烯和许多植物信号途径(包括光、胁迫条件、病原侵染及其它植物激素)在不同的植物发育及抗性过程中存在复杂的相互作用。因此我们将致力于研究乙烯作用过程的分子步骤及其调控机制,阐明在植物发育、衰老和胁迫抗性中乙烯和其他信号途径的相互作用机理。同时,我们将结合功能基因组学和蛋白质组学来探索系统研究植物信号转导的新方法。

固有免疫是机体应对于病原微生物感染而进行反击的第一道屏障。固有免疫的不当调控可引起许多疾病,包括各种感染性疾病、自身免疫疾病和多种过敏反应等。固有免疫的研究是当前生物学、医学研究的热点,其中还有很多问题有待于更深入的研究,如细菌、病毒DNA在胞浆中的受体是什么?Mda5/RIG-I/VISA通路抗病毒的作用机制是什么?不同I型干扰素受不同转录因子的调控机制、固有免疫细胞激活后如何调控不同细胞因子的表达等等还很不清楚。
经典的研究方法:从基因到基因敲除到功能研究已显示出自己的局限性:特定功能或通路中已知的基因越来越多地被敲除,越来越少的基因可供研究。如何找到新的有重要功能的基因就显得尤为重要。我们将结合功能基因组学的方法,从功能(激活特异基因表达或与固有免疫关键分子相结合)入手,寻找固有免疫中调控不同细胞信号通路的新基因,包括已知的,但未曾报道在固有免疫中有作用的基因,我们将1)利用cDNA文库进行与固有免疫相关的大规模、高通量的基因克隆与功能筛选;2)利用酵母双杂交寻找与固有免疫关键蛋白相结合的蛋白;3)分离纯化抗病毒通路关键蛋白并结合肽谱分析寻找与固有免疫关键蛋白相结合的蛋白。我们将利用免疫学,细胞生物学,分子生物学,生物化学,结构生物学等多种技术来研究这些基因的功能及作用机制。对这些重要免疫因子表达调控的研究,将为人们了解固有免疫中不同信号分子、不同信号通路的激活机制、不同细胞因子应对于相同或不同感染而受到的调控机制具有重要意义。同时,通过大规模的筛选,找到特异性调控某个(类)细胞因子表达的关键分子,可为人类设计新一代的抗炎症、抗病毒药物找到靶标分子。
主要的研究方案:
1)固有免疫中重要细胞因子的启动子的克隆分析
2)不同感染处理的巨噬细胞cDNA表达文库的制备
3)用于文库筛选的细胞系的建立及大规模、高通量筛选

1.感觉神经器官的发育 (Sensory Organ Development)
脊椎动物不同于其它动物的一个重要特征是它们身体前半部有大量丰富的旁侧感觉神经及其依附的感觉器官。这些器官包括嗅上皮,瞳仁,垂体,三叉神经器官,内耳,鳃弓神经器官,和侧线(鱼及两栖类特有),被誉为脊椎动物独有的进化标志。有趣的是,所有感觉器官的形态前体十分相似:它们都在外胚层特定的位置加厚形成基板。 经典胚胎学和近代发育生物学研究在过去的一百年间不断地争论这些感觉器官是否具有发育同源性。至本世纪,争论的焦点为:在脊椎动物发育的原肠胚期是否存在一个特定的前基板区,并由此分化出头部周围感觉神经系统。我们过去专注于内耳的发生研究,并于近两年初步揭开从前基板区到内耳命运决定的发育路径。 我们将深入探讨前基板区是如何形成和分化的,并比较各种感觉器官形成机制的异同。
2. 听觉形成与再生(Hearing Development and Regeneration)
据统计,全球逾一亿人口患有各种各样听力丧失的疾病,其中大部分的听力损伤缘于内耳中听力功能细胞—毛细胞的损伤和无法再生或听觉神经萎缩,死亡。例如,老年性的听力衰退主因为内耳中毛细胞数量的明显减少:人类初生时每个内耳中具有1.6万-3万个毛细胞,但一经成熟,这些毛细胞在个体生长发育过程中不再增殖和再生,并因内在病变(遗传及后天获得的疾病,药物中毒等)和/或环境因素(污染,噪声,随声听等)而不断减少。由于与内耳相连的听觉神经分布和与毛细胞的配置十分精巧和复杂,所以耳蜗和干细胞移植均产生无法预期的并发症。因此目前治疗听力损伤最好的方法是希望在病人内耳的正确位置诱导毛细胞的适量再生,及与听觉神经建立准确的联系。研究毛细胞的发育机制,以及研究毛细胞损伤后再生障碍的机制,对于听觉及其康复的研究至关重要。我们实验室将毛细胞的发育和再生机理作为研究的长期目标,计划以斑马鱼为主要模式动物,用遗传,发育及经典胚胎生物学的方法开展研究工作。我们同时还将研究听觉神经的遗传发育,以探讨其再生可行性和如何与成熟毛细胞建立精准的联接。

科研领域描述
My laboratory is interested in two areas of research, aging and cell death. In aging research, we focused on the gene ASIC2 (Acid Sensing Ion Channel 2), which encode an ion channel belongs to the superfamily of DEG/ENaC (Degnerin/Epithelial Sodium Channel). ASIC2 is specifically expressed in mammalian central nervous system. However, its function is largely unknown. To study ASIC2 function in vivo, we generated transgenic flies. We unexpectedly discovered that ASIC2 induced a novel longevity pathway, distinct from the well known pathways such as diet restriction or insulin/IGF pathways. Currently, the mechanism of ASIC2 function is under investigation in fruit flies and nematodes.
Cell death during developmental or pathological conditions can be classified into four types based on morphology and genetic pathways: apoptosis, autophagy, programmed necrosis and vesicular necrosis. In general, necrosis occurs at an older age and associated with conditions of massive tissue damages, such as during traumatic brain injury, stroke, seizure and muscular dystrophy. Because of the lack of understanding of vesicular necrosis and paucity of therapies, we generated a genetic model of vesicular necrosis aim at discovering genes and drugs to modify the progression of acute cell injury. Currently, we are characterizing several genes, and searching for more genes using fly genetic screen. Our aim is to build the molecular and cell biological framework of vesicular necrosis.

科研领域描述
本实验室主要兴趣在于:
1.植物超长链脂肪酸合成途径的研究。
2.超长链脂肪酸调控植物细胞伸长的分子机制研究。
脂肪酸是指一端含有一个羧基的长的脂肪族碳氢链,在生物体内大部分脂肪酸都以脂质形式存在。超长链脂肪酸是指碳骨架长度超过20个碳原子的脂肪酸,在植物体内这类脂肪酸主要集中于细胞膜鞘脂及植物表面蜡质中,其生物学作用不很清楚。
实验室近几年来以陆地棉和无长绒无短绒突变体为实验材料,通过构建大规模棉花转录组基因芯片,分离、鉴定和研究棉花纤维伸长相关基因。其中,超长链脂肪酸(VLCFA)合成途径是被鉴定为一条重要的在纤维发育期显著上调的代谢途径,我们克隆并鉴定编码3-酮脂酰-CoA合酶、3-酮脂酰-CoA还原酶及烯酰-CoA还原酶的棉花cDNA。为验证其生物学功能,将它们互补相对应的酵母突变体中,并使用气相色谱质谱联用仪对互补棉花基因的酵母突变体中的脂肪酸进行定性和定量分析。我们最新的研究发现VLCFA通过激活乙烯合成途径不仅能够促进棉纤维伸长发育,而且还能促进拟南芥茎细胞伸长。这是关于VLCFA可能作为植物信号分子的首次报道,对于VLCFA如何调控植物发育的进一步研究具有重要意义。

本实验室主要兴趣在于:
1.神经发育的分子机理。
2.社会行为的分子生物学。
极性是细胞的一个基本性质。神经细胞有轴突和树突,它们起不同的作用,树突一般接受信号,而轴突通常发送信号。如果没有神经细胞的极性,神经系统的信息传递就会紊乱。实验室在分子和亚细胞水平研究神经细胞极性发生的机理,除了可以帮助基础理解以外,如果能知道怎样形成轴突,也许可以提示如何在损伤后帮助促进神经纤维再生。目前实验室主要研究调节神经细胞极性的信号转导通路。
我们通过遗传学途径研究社会行为的分子机理。主要用果蝇和鼠研究同性间争斗、异性间求偶、和亲子间抚育等行为。用可以定量的实验模型,观察行为的模式和变化。用遗传学方法,控制特定脑区神经活动,以确立脑中参与特定行为的区域。通过分析基因突变后的行为表型,找到调控行为的分子。希望理解一个行为执行需要的分子和神经通路,了解行为如何发育,行为发育的分子和细胞机理。

本实验室主要兴趣在于:
1.非孟德尔遗传的生物学意义
2.非孟德尔遗传的分子机理
3.植物生殖的细胞分子生物学
非孟德尔遗传指线粒体和质体基因组的遗传。人们都知道真核生命的这些细胞质基因组通常呈现单亲遗传。为什么要单亲遗传?为什么细胞核和细胞质中的遗传物质以不同的方式传递给子代?非孟德尔遗传对真核生命的形成和进化有怎样的作用和意义?本研究组利用不同的实验模式研究这些生命的基本问题。
非孟德尔遗传现象发现于近100年前,但至今分子调控机制不详。常规的理化诱变方法未能在模式动植物中获得相关的突变体,说明其分子调控机制的复杂性。本研究组在完成相关细胞学机理评估的基础上,正在尝试从蛋白质组学的角度探索非孟德尔遗传的基因分子生物学调控机理。
植物的有性生殖是一个复杂的生命活动过程,与非孟德尔遗传有着密切的关联。本研究组同时对被子植物有性生殖过程中的细胞分化、受精等重要的生命活动过程进行研究。

本实验室主要兴趣在于:
1 细胞钙信号转导的微观过程和分子机理;
2 心脏疾病的分子病理机制和生物医学工程;
3 感觉传入诱导的大脑神经网络发育。
钙离子是细胞最古老、作用最广泛的胞内信使。本实验室在激光共聚焦显微成像技术和膜片钳电生理技术的基础上,建立了单通道光学探测和通道间钙信号转导的研究技术,在国际上居领先优势。将该技术与分子生物学、功能蛋白组学、电子显微镜技术相配合,可以从分子间相互作用的微观水平阐述细胞钙信号是如何产生、放大和精细调控的。
分子间钙信号转导是心肌细胞兴奋收缩耦联的核心环节,其异常与心力衰竭、心律失常等重要疾病密切相关。我们最近在心衰分子病理机制方面取得突破,发现钙信号分子过程的病理改变远早于细胞和心肌组织的功能变化,其中关键分子事件是联系细胞膜与肌质网的蛋白junctophilin表达下降。我们正进一步寻找相关的分子调控机制,并在此基础上探索心衰早期诊断新技术和逆转心衰的生物医学工程方案。
脑和心脏一样是人体最重要的器官,均通过离子通道产生和传递兴奋。本实验室在研究生自由探索兴趣的驱使下,利用我们强有力的电生理优势和数据处理能力,以“同步发放链”理论框架为基础,通过分析不同感觉输入条件下神经细胞电活动的时序规律,研究后天经验如何影响大脑皮层神经网络的发育性构建,已取得重要阶段性发现。

RESEARCH INTERESTS
Our major interest is to understand how cells communicate with each other and how they sense the environment.
Important membrane and cell surface proteins are our major targets. Multiple biochemical and structural biological techniques including negative staining EM, cryo-EM, NMR and X-ray crystallography will be applied.
DIRECTIONS AND PROJECTS
Our laboratory is pursuing research in three major directions: Plant hormone receptors, Human GPCRs in nervous system, and Virus/host recognition. We are also interested in developing novel eukaryotic expression systems for structural biology studies and pharmaceutical industry.
Research Direction 1: Structure and function of Plant Hormone Receptors
Project 1: Molecular and Structural biology of plant ethylene receptors
Ethylene (C2H4), as a plant growth substance, has the simplest structure. Unlike the rest of the plant hormone compounds, it is a gaseous hormone. Ethylene is produced in all higher plants. It has evolved as the central regulator of cell death programs in plants and is usually associated with flower opening, fruit ripening, stress response, wound healing and host defense.
It had been widely believed that all ethylene receptors possess histidine kinase activity and the signal pathway resembles the two-component system, the same way as their sequence homologues in bacteria. We were the first to demonstrate that some of them were actually ser/thr kinases, and suggest that it may serve as an evolutionary bridge connecting the ancient histidine kinases (HKs) in prokaryotes to later evolved ser/thr kinases (STKs) in eukaryotes.
We all like to know where we came from. Knowing where we came from can help us go forward. The structure determination of ethylene receptors will address the connections and the differences between HK and STK at atomic level.
Other projects will be initiated soon in plant hormone field.
Research direction 2: Structure and function of class C G protein-coupled receptors (GPCR)
Project 2: Structure study, ligand induced dimerization and conformational regulation of human taste receptors type 1 (T1R1, T1R2 and T1R3).
Introduction: Taste receptors significantly impact glucose homeostasis, obesity and diabetes. The atomic structure will provide basis for new therapeutic treatments to these diseases and guide new drug design. At the same time, it will also help us on the discovery of new food additives with no or fewer side effects.
Research direction 3: Virus/Host Recognition
Underdevelopment, coming soon…

科研领域描述
本实验室主要兴趣在于:
1 以斑马鱼为模式研究脊椎动物早期胚胎发育基因表达调控与器官形成机制,特别是血液与心血管系统以及胰腺等内脏器官的细胞分化与发育。
2 斑马鱼功能基因组研究。
斑马鱼(Danio rerio)是进行发育生物学研究的理想模式脊椎动物。本实验室以功能基因组研究手段为切入点,通过筛选斑马鱼中与血液、心血管或胰腺发育相关的突变体与基因,鉴定基因的表达图谱,并进行基因功能以及表达调控机制的研究。
(1)新基因的筛选:应用以Tol2转座子为基础的“增强子诱捕”(enhancer-trap)技术、以绿色荧光蛋白(GFP)或红色荧光蛋白(RFP)为报告基因大规模筛选具有组织特异性表达图式的转基因斑马鱼,以及斑马鱼早期胚胎发育相关基因,以建立相应的转基因鱼系与斑马鱼基因表达模式信息库。迄今已获得1, 670种报告基因带有特异表达模式的子代鱼系(F1),其中包括30种在胰腺中特异表达报告基因和40 多种在血液和/或心血管系统特异表达报告基因的鱼系;鉴定了其中的118个Tol2插入位点,附近的基因大部分为尚未见报道的新基因。这部分工作由我室与美国加州大学洛杉矶分校(UCLA)林硕教授的实验室共同合作进行。
(2)突变体的筛选:在与美国国立卫生研究院(NIH)下属的国立人类基因组研究所(NHGRI)Shawn Burgess教授进行科研合作的基础上,在国内建立了斑马鱼基因插入诱变技术平台;应用反转录病毒插入诱变技术对斑马鱼进行大规模基因饱和突变筛选,以建立斑马鱼全基因组随机突变文库与突变体信息库。这部分工作采用了高通量的LM-PCR技术,辅以大规模测序与精子冻存保种的全新策略。目前已筛选到了244个基因内的插入,其中大部分为功能未知的新基因。
胰腺是一个既包含内分泌腺又包含外分泌腺的特殊的复合器官,它的形态发生既涉及到多种信号通路参与的复杂的细胞分化过程,又存在细胞大量扩增的发育阶段,是研究体内细胞增殖与分化的良好模式。同时,糖尿病、胰腺癌等严重危害人类健康的疾病与胰腺的发育缺陷与功能失调密切相关,因而胰腺发育机制的研究具有不言而喻的理论与应用价值。然而,胰腺作为一个内脏器官,由于其深陷在身体内部而难以进行深入研究,因此胰腺的发育机制研究相对其它器官而言比较滞后。在上述通过Tol2增强子诱捕筛选得到的胰腺被特异标记的鱼系中,GFP报告基因的可视标记无疑为我们研究胰腺提供了一个极好的条件。我们将充分发挥上述转基因鱼系与突变体的优势,以胰腺的发育为模式,研究细胞增殖与分化在胰腺形成中的作用及其机制。
人类对脊椎动物造血系统以及心血管系统的研究已有几百年的历史,但是它们的发育机制尚未完全阐明。脊椎动物进化过程中造血过程与心血管的发生是高度保守的,并且造血系统和血管系统共同起源于腹侧中胚层(ventral mesoderm),两者可能具有共同的前体细胞—成血成血管干细胞(hemangioblast),经进一步诱导分化形成成血细胞(hematopoietic stem cell)及成血管细胞(angioblast)。丰富的细胞类型与逐级的分化过程使造血系统成为研究体内细胞增殖与分化调控机制的理想体系。斑马鱼胚胎在受精后24小时即可开始心脏跳动与血液循环,并且胚胎通体透明,血红素呈红色,在体视镜下极易观察;更为宝贵的是,循环系统有缺陷的斑马鱼胚胎依然能够依靠体表的气体交换存活几天,这样就为我们研究发生缺陷的原因争取了时间。无疑,斑马鱼是开展血液与心血管发育机制研究的理想材料。我们将从上述Tol2增强子诱捕与反转录病毒插入诱变的筛选结果中,选择血液和/或心血管系统特异的基因与突变体,深入研究细胞增殖与分化在脊椎动物血液与心血管系统发育过程中的作用及其调控机制。

科研领域描述
本实验室主要兴趣在于:
1. 人类重要蛋白的结构和生物功能研究。
2. 乙肝病毒preS表面抗原及流感病毒神经氨酸酶的功能和结构研究。
3. 蛋白质与核酸相互作用机制的研究。
一些参与基本生物学过程的重要蛋白质的突变所引起的功能失调会导致细胞的非正常发育或功能丧失,并最终产生包括肿瘤在内的多种疾病,因此,对这些蛋白的结构和功能开展研究具有重要的生物学意义。研究室主要选取一些与肿瘤等人类重大疾病相关蛋白及一些功能未知的但可能具有重要生物学意义的新型人类蛋白为靶蛋白,研究其结构和功能的分子基础,研究蛋白质与蛋白质以及蛋白质与其它生物分子相互识别和相互作用的分子机制、调控网络关系,以及蛋白质功能的失调与一些重大疾病的发生和发展的关系及分子机理。此外,我们与杨震教授、罗明教授和魏丽萍教授合作开展流感病毒的抗病毒药物的研究,旨在确认用于治疗禽流感病毒的感染的有效的小分子药物。
乙型病毒性肝炎是由乙型肝炎病毒(HBV)引起的一种世界性疾病,严重威胁着人类的生命与健康。据统计,全世界乙型肝炎表面抗原(HBsAg)无症状携带者超过3亿,在我国有1亿以上。每年都有大约一百万人死于由慢性肝炎转化为肝硬变或肝癌。乙型肝炎病毒表面抗原preS携带宿主细胞受体识别位点,在乙肝病毒感染过程中起着重要的作用。我们希望通过对preS的功能和结构的深入研究,进一步了解HBV病毒的入侵和融合作用机制,并且探讨preS在诊断、治疗和疫苗方面的应用研究。
此外,研究室还对蛋白质与RNA间相互作用机制等开展研究。

以陆地棉徐州142和它的无长绒无短绒突变体(fuzless-lintless, fl)为实验材料,建立大规模功能基因筛选与分离克隆的新体系,建立广泛的植物功能基因组学研究、高通量基因组信息分析和大规模基因功能分析的技术平台,已建成目前为止世界上规模最大的含有29,000多个棉花cDNA的基因芯片并利用该芯片分离和克隆了一批在纤维突起、特别是伸长阶段特异性表达的棉花基因,研究并发现发现乙烯合成是纤维伸长过程中最显著上调的代谢途径。筛选了13个钙调蛋白依赖型蛋白激酶基因,发现钙调蛋白依赖型蛋白激酶抑制剂TFP可以抑制纤维细胞的伸长,乙烯不能恢复这种抑制作用,表明CDPK介导的钙信号通路可能位于乙烯信号下游。发现GhAPX1基因受H2O2和乙烯的调控,外加H2O2能够促进纤维伸长,而乙烯能促进内源H2O2的释放,表明乙烯可能通过CDPK激活NADPH氧化酶,释放活性氧,促进纤维伸长。克隆并鉴定了10个VLCFA延伸酶基因,研究了棉花VLCFA合成途径关键酶GhKCR和GhKCS的功能,发现VLCFA能够显著促进棉纤维伸长并诱导ACO基因高表达,促进乙烯释放。外源施加VLCFA抑制剂ACE能抑制纤维细胞的伸长和内源乙烯的释放。ACE的抑制作用可以被乙烯所恢复,但VLCFA不能恢复AVG的抑制作用。
2、拟南芥转录调控因子家族基因的克隆与研究
克隆了146个AP2/EREBP转录调控因子家族基因(该家族最多可能有147个基因),并进行了大规模基因表达谱分析,找到了一批可能参与调控各种生理过程的受不同环境条件或处理诱导表达的转录调控因子基因。通过对拟南芥ATH1基因芯片数据的分析,鉴定了一个受干旱胁迫高水平诱导的cDNA片段, 并用RACE方法获得了其全长cDNA。PCR及定量实时PCR分析表明, 该基因在经干旱、紫外线照射、脱落酸、高盐以及水杨酸等胁迫条件处理后表达量均有显著提高,特别是干旱处理后短时间内表达量迅速提高,3 h后即提高到对照样品的430多倍。通过多序列比对和系统进化分析,将该基因归于DREB亚家族。由于该基因编码蛋白含有典型的AP2/EREBP DNA结合结构域,并在N端有一段富含谷氨酰氨残基的区域,所以将它命名为QRAP2 (Glutamine-rich AP2)。凝胶阻滞实验结果显示, QRAP2蛋白能够特异结合DRE顺式元件序列但不能与mDRE和GCC等非相关元件结合。酵母单杂交实验表明,QRAP2蛋白全长序列或其N端112个氨基酸与GAL4 DNA结合结构域形成的融合蛋白表现出转录激活功能,而其C端135个氨基酸与GAL4 DNA结合结构域的融合蛋白则没有表现出转录激活活性。现有资料的分析表明,QRAP2是AP2/EREBP转录因子家族的新成员,可能在干旱胁迫条件下参与激活相关下游基因的表达。还研究了TINY2等多个转录因子的表达特性。正在通过拟南芥缺失突变体对参与植物抗性反应及植物激素ABA信号转导相关基因进行系统性功能研究。

1 赤霉素信号与逆境及脱落酸信号之间的交互作用。
赤霉素合成或信号转导中某些关键基因的突变导致作物矮化,可增强作物的抗逆能力并提高作物的产量,故被称为绿色革命基因。对赤霉素信号转导分子机理的解析既具有重要的理论意义又有广阔的应用前景。我们以拟南芥和水稻作为模式植物,通过基因组学、分子遗传学、生物化学等方法和手段对植物发育过程中赤霉素信号转导过程进行深入和系统的研究,以期发现赤霉素信号转导过程中的新的组成分子,研究它们与已知蛋白之间交互作用的分子网络。
逆境是影响植物生长发育的主要环境因子。逆境信号转导中脱落酸起非常重要的作用。我们以拟南芥和水稻作为模式植物进行逆境及脱落酸信号转导途径中关键因子的发掘,研究它们的生物学功能及其与农艺形状的关系。另外一个研究重点是,用遗传学、生物化学和分子遗传学方法揭示植物发育及逆境中赤霉素与脱落酸信号之间的交互作用。

研究兴趣主要集中在种群生态学和分子生态学
栖息地破坏是物种绝灭的最主要的原因之一。日益加剧的人类活动将生物原有栖息地分割成小的斑块,大量物种就只能生活于这样片段化的栖息地中。小的斑块只能维持有限数量的种群,面临很高的绝灭风险,而现有种群迁出个体可以在空的栖息地中重新建立种群,物种可以在绝灭和重定殖的平衡中得以维持,即以集合种群(metapopulation)形式存在。栖息地片段化将给生活于其中的物种带来怎样的影响,同时物种又是如何适应栖息地片段化并得以续存,这是我们现在所关注的主要问题,这对探讨物种的保护策略及保护区设计原则具有重要意义。本研究组以庆网蛱蝶(Melitaea cinxia)为主要研究对象,通过和芬兰庆网蛱蝶种群的比较研究,探讨不同片段化程度下集合种群结构动态及其影响因素,从而分析栖息地片段化对庆网蛱蝶的影响,以及庆网蛱蝶的适应机制。目前,主要涉及集合种群动态对迁移能力快速进化的影响、近交衰退对集合种群动态的影响、种群结构和遗传结构、雄蝶的求偶及交配策略、蝴蝶的高温适应及温度调节等方面。
将分子生物学技术应用到生态学研究中,是对生态学研究的有利补充,这就是分子生态学。利用分子生物学技术可以研究物种的系统发育、种群的遗传分化、个体的亲缘关系等。研究对象除了庆网蛱蝶外,还有尾蛱蝶、网蛱蝶等昆虫,以及亚洲黑熊等大型动物(和其他组的合作研究)。
