单细胞真核生物的miRNA系统及其进化意义
单细胞真核生物 miRNA 贾第虫 进化
font style='font-size:12px;'>
2010/4/20
miRNA 系统在高等多细胞真核生物中得到了广泛深入的研究。近年来，人们在单细胞真核生物上的miRNA研究也取得了重要进展。这不仅丰富了人们对miRNA在整个生物界中的认识，更重要的是对于揭示miRNA这一表达调节系统是如何在生物界中起源进化的问题具有重要意义。该文结合作者在最低等单细胞真核生物——贾第虫上的研究结果，对该领域的研究进展作一概述，并对有关miRNA这一系统的起源进化问题进行了探讨。
动物毒素：从单一成分到组学研究，从理化性质到人类疾病机理，从粗毒利用到理性药物设计
动物毒素 蛇毒 两栖动物 皮肤分泌物 节肢动物 昆虫 唾液腺
font style='font-size:12px;'>
2010/4/20
为了适应环境，很多动物在长期的进化过程中演化出了丰富的毒素及相关分泌物。这些物质中包含了高活性、作用专一的蛋白和多肽。由于它们作用的特异性和专一性，成为蛋白质多肽结构与功能研究的良好模型，也成为研究人类自身生理病理机制的工具和线索，同时也是开发临床诊断试剂和治疗药物的天然宝库。该文综述了中国科学院昆明动物研究所30多年来立足于我国丰富的有毒动物资源，对陆生有毒动物，包括蛇毒、两栖类皮肤分泌物及节肢...
三叶因子（trefoil factor, TFF）家族是具有一个或多个三叶因子结构域的蛋白质多肽，在进化上具有高度的保守性，具有耐热、耐酶消化的理化特性。哺乳动物的TFF有三个成员(TFF1、TFF2和TFF3)。黏膜组织，如胃肠道和呼吸道黏膜等是TFF的主要合成场所。生理条件下，TFF的分布具有组织专一性，具有黏膜保护和创伤修复作用。TFF在肿瘤组织中广泛表达，在肿瘤的发生、发展、侵袭、转移过程...
