本发明涉及微生物次生代谢产物技术领域，具体涉及一种激活放线菌沉默次生代谢产物合成基因簇表达的方法。
背景技术
放线菌(Actinomycetes)作为微生物的重要组成部分，具有复杂的形态分化机制和代谢调控网络，可以产生大量结构新颖的活性物质，是天然药用活性先导化合物的重要来源，被广泛应用于基础理论和应用研究。以放线菌中的主要类群链霉菌(Streptomyces)为例，大量的全基因组测序分析表明链霉菌含有丰富的次生代谢产物合成基因簇，目前发现了约6000种抗生素以及抗肿瘤、抗寄生虫和免疫抑制剂等药理活性物质。基因组测序结果显示，每个链霉菌属菌株的基因组中有20～40个次生代谢产物的生物合成基因簇(BGCs)，远超过实际从链霉菌中分离得到的次生代谢产物的数量。比如在天蓝色链霉菌(Streptomyces coelicolor)A3(2)中发现的次生代谢产物只有放线紫红素(ACT)、钙依赖抗生素(Calcium-dependent antibiotic，CDA)、十一烷基灵菌红素(RED)和次甲基霉素(Mmy)等，而根据生物信息学分析，S.coelicolorA3(2)能够产生20种以上的次生代谢产物。其中，相当一部分原因是由于培养条件的限制导致大部分合成基因簇处于“沉默”或低表达状态从而无法获得相应的次生代谢产物。因此，如何有效激活放线菌中大量存在的沉默次生代谢产物合成基因簇、发掘新的次生代谢产物是当今微生物天然产物领域的研究热点和难点。
为了激活放线菌沉默基因簇的表达，获得更多新型活性次生代谢产物，寻找和开发激活沉默基因簇的新技术、新方法成为了该领域的热点前沿。目前，沉默BGCs常用的激活策略主要分为两种：一是在天然宿主菌中解除沉默BGCs的抑制因素，主要包括改变培养条件，共培养，编辑调控体系，引入强启动子等；二是避开原始菌中复杂的调控体系，直接将编码沉默BGCs的操纵子克隆到异源宿主中表达或重构沉默BGCs的控制元件后转移到异源宿主中。虽然这些常用策略已展现出了一定的优势，但也表现出了一定的局限性：传统的改善培养条件和共培养缺乏一种高通量筛选体系，工作量较大；利用基因操作激活沉默BGCs的策略不适用于培养困难或难于遗传操作的菌种；基于异源表达的激活策略虽避开了天然宿主的限制因素，但简单的异源宿主环境通常无法提供次生代谢产物生物合成的调控网络和代谢需求等。
研究发现一些化学物质可以抑制链霉菌中特定酶的活性，增加其生长压力，进而产生代谢变化。如Craney等发现一些小分子可通过抑制脂肪酸合成酶来改变链霉菌的次生代谢产物及提高抗生素产量，γ-Butyrolactones可以将S.hygroscopicus中抗真菌抗生素Validamycin的产量提升30％。群体感应(Quorum Sensing，QS)是一种微生物细胞之间的信息交流机制，近年来的研究发现QS不仅在同种微生物细胞交流中发挥作用，甚至在微生物细胞的跨种乃至跨界识别和交流过程中发挥作用，故QS信号分子有可能被作为相互拮抗的微生物细胞之间识别的信号分子，激活微生物拮抗相关基因用于细菌的竞争。基于这一假设，我们推测通过外源添加QS信号分子可被用于激活放线菌中的沉默BGCs基因的表达，从而为发掘大量存在的BGCs资源，促进新结构天然产物的发现有着极为重要的意义。
病原细菌和真菌感染逐年增加的发病率、致死率和不断增强的耐药性使其预防和治疗成为全球性的难题，人类即将面临无药可用的地步，挖掘新型抗菌药物和开发新的治疗策略已经迫在眉睫。基于群体感应信号分子作为药物靶点已成为解决病原菌感染的关键，正逐渐成为微生物群体感应领域研究的前沿热点，但关于使用群体感应信号分子激活放线菌沉默BGCs的相关方法还未见报道。模式真菌白色念珠菌(Candida albicans)和细菌铜绿假单胞菌(Pseudomonas aeruginosa)作为常见人体条件致病菌，是近年来研究的热点之一，其信号分子法尼醇(Farnesol)、酪醇(Tyrosol)和3-oxo-C12-HSL等长期以来已得到了广泛的研究，可作为用于检验群体感应信号分子激活放线菌BGCs表达的合适代表性信号分子。
为此，本发明旨在提供一种激活放线菌沉默次生代谢产物合成基因簇表达的新方法，以解决上述现有技术中的问题。

实施例2：天蓝色链霉菌A3(2)生长测定
培养至稳定期的天蓝色链霉菌A3(2)按1:100转接至发酵培养基中，定点取样，采用称取链霉菌细胞干重的方法，测量并绘制链霉菌的生长曲线图。其中，48h后链霉菌开始进入生长对数期，在96h左右到达对数末期，120h后进入稳定期。
实施例3：天蓝色链霉菌A3(2)中次生代谢基因簇的功能基因的定量分析
将天蓝色链霉菌A3(2)在发酵培养基中30℃培养至对数中后期，分别加入细菌、真菌相关信号分子(100μM Farnesol、100μM Tyrosol、100μM 3-oxo-C12-HSL、100μMTryptophol)培养2.5h后，离心收集菌体。
(1)天蓝色链霉菌A3(2)总RNA提取，使用RNA提取试剂盒(天根生物科技，中国)，具体操作如下：
①用含有10mg/mL溶菌酶的100μL dd H2O彻底重悬菌体，室温孵育15min；
②加入350μL裂解液RL(在使用之间已加入β-巯基乙醇)，涡旋振荡混匀；
③加入250μL无水乙醇。将得到的溶液和沉淀一起转入吸附柱CR3中，12000rpm离心1min，倒掉废液，将吸附柱放回收集管中；
④向吸附柱CR3中加入350μL去蛋白液RW1，12000rpm离心1min，弃废液，将吸附柱放回收集管中；
⑤DNase I工作液的配制：取10μL DNase I储存液放入新的RNase-Free离心管中，加入70μL RDD缓冲液，轻柔混匀；
⑥向吸附柱CR3中央加入80μL的DNase I工作液，室温放置15min；
⑦向吸附柱CR3中加入350μL去漂洗液RW1，12000rpm离心1min，弃废液，将吸附柱放回收集管中；
⑧向吸附柱CR3中加入500μL去蛋白液RW(使用前已加乙醇)，室温放置2min，12000rpm离心1min，弃废液，将吸附柱放回收集管中，并重复一次；
⑨12000rpm离心2min，倒掉废液，将吸附柱CR3置于室温放置10min；
⑩将吸附柱CR3转入一个新的RNase-Free离心管中，向吸附膜的中间部位悬空滴加50μL RNase-Free dd H2O，室温放置2min，12000rpm离心2min，得到的RNA样品利用琼脂糖凝胶电泳检测RNA的完整性和纯度，采用酶标仪测定浓度。
(2)RNA反转录和定量分析
首先按照TransGen公司反转录试剂盒进行操作。按照表1反转录体系和表2反转录程序产生cDNA，然后按照表3的定量体系、表4的定量相关引物和表5的定量程序，利用LightCycler 96热循环仪(Roche，美国)进行qRT-PCR反应。其中，使用天蓝色链霉菌A3(2)的hrdB基因作为内参。
表1RNA反转录体系
表2RNA反转录程序
表3定量体系
表4定量相关引物
表5定量程序
通过本发明的上述实施例，本发明通过研究群体感应信号分子Farnesol、Tyrosol、3-oxo-C12-HSL和Tryptophol对天蓝色链霉菌A3(2)(模式放线菌研究模型)沉默BGCs激活的作用，开发了一种新型信号分子激活放线菌沉默基因簇的表达的方法，其为一种快速、高效激活不同放线菌中沉默BGCs的策略，将为激活大量存在的沉默BGCs宝库，深入发掘新型放线菌天然产物提供有效途径，从而为医药、农业等多领域的研发贡献更多更好的新型先导化合物。
以上具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
