蠕虫与我们人类共有的、6亿千年前在海洋中漫游的最后祖先可能早有一个复杂的大脑，能够释放激素到血液中，也能够与多种感觉器官连接。这个证据并不是来自于新发现的化石，而是来自于对存在于当今的动物的microRNAs的研究。microRNAs是能够调节基因表达的小RNA分子。
德研究人员发现MicroRNAs能够关闭基因
德国 MicroRNAs 关闭基因
2010/8/18
RNA分子是基因的移动信使。它在蛋白质产生过程中将信息从DNA传递到核糖体。除了这个mRNAs，所有的生物体都具有能够干扰mRNAs和蛋白质产生的microRNAs。德国佛雷堡大学的生物学家，包括Wolfgang Frank博士和植物生物技术教授Ralf Reski联合发现这样micro RNAs也能够直接进入与基因联系，有效地关闭这个进程中的基因。
染色体上聚集的microRNAs具有更多共同的靶基因
microRNA 前体miRNA(pre-miRNA) 成簇的miRNA(clustered miRNAs) miRNA 基因组学(microRNA genomics)
2008/5/19
miRNAs是一类~22nt、在转录后调节mRNAs表达的内源性非编码RNA。人类miRNA具有成簇聚集于染色体上的特点。文章系统分析了人基因组簇内miRNA各成员的预测靶基因之间的关系，发现簇内miRNA各成员具有更多共同的靶基因， 表明簇内miRNA各成员功能相似。仔细分析簇内miRNA和mRNA的结合位点，发现有两种类型：一种是簇内miRNAs可能竞争性结合同一个靶基因的同一个结合位点；另一...
植物microRNAs研究进展
植物microRNAs 转录后基因调控 植物生长发育
2008/1/26
摘要植物microRNAs(miRNAs)是一类与RNA诱导沉默复合体相关的约由22个核苷酸组成的单链小RNA分子, 其主要功能是, 通过特异性剪切靶mRNA或阻遏靶mRNA的正常翻译在转录后水平调控基因的负表达。植物miRNAs的靶标主要是参与调控植物生长发育和防御应答的转录因子家族。文章主要综述miRNAs在植物体内的生物发生、作用机制及其调控作用研究新进展。
