| 1 | The role and clinical implications of microRNAs in hepatocellular carcinoma显示文摘Hepatocellular carcinoma (HCC) is common and one of the most aggressive of all human cancers. Recent studies have indicated that miRNAs, a class of small noncoding RNAs that regulate gene expression post-transcriptionally, directly contribute to HCC by targeting many critical regulatory genes. Several miRNAs are involved in hepatitis B or hepatitis C virus replication and virus-induced changes, whereas others participate in multiple intracellular signaling pathways that modulate apoptosis, cell cycle checkpoints, and growth-factor-stimulated responses. When disturbed, these pathways appear to result in malignant transformation and ultimately HCC development. Recently, miRNAs circulating in the blood have acted as possible early diagnostic markers for HCC. These miRNA also could serve as indicators with respect to drug efficacy and be prognostic in HCC patients. Such biomarkers would assist stratification of HCC patients and help direct personalized therapy. Here, we summarize recent advances regarding the role of miRNAs in HCC development and progression. Our expectation is that these and ongoing studies will contribute to the understanding of the multiple roles of these small noncoding RNAs in liver tumorigenesis. | ZHAO Xue YANG Zhen LI GuangBing LI DongKai ZHAO Yi WU Yan ROBSON Simon C.

| 2 | 干扰水稻瘤矮病毒(RGDV)非结构蛋白(Pns12)的表达抑制病毒在介体昆虫培养细胞内的复制显示文摘水稻瘤矮病毒(Rice gall dwarf virus,RGDV)属呼肠孤病毒科(Reoviridae)植物呼肠孤病毒属(Phytoreovirus),由介体电光叶蝉(Recilia dorsalis)以持久增殖型方式传播,其基因组第12条片段编码的非结构蛋白(nonstructural protein,Pns12)是提供病毒复制和子代病毒粒体装配场所——病毒原质(viroplasm)的组分之一。为了明确Pns12在RGDV侵染介体电光叶蝉培养细胞中的功能,本研究通过原核表达的Pns12蛋白免疫注射兔(Oryctolagus cuniculus),制备Pns12抗体,并应用免疫荧光标记和RNA干扰(RNA interference,RNAi)技术研究Pns12在介体培养细胞内的定位和参与病毒原质形成的过程。共聚焦显微镜观察到,病毒侵染的细胞中,与荧光素交联的Pns12抗体特异地标记在病毒原质上。干扰Pns12蛋白表达后,可有效地阻碍病毒原质的形成、子代病毒粒体的组装和病毒非结构蛋白Pns12和外壳蛋白P8蛋白的表达,表明Pns12作为病毒原质的组分参与了RGDV在介体培养细胞内的复制。也表明,Pns12可作为理想的靶标用于阻断电光叶蝉携带和传播RGDV。 | 郑立敏 刘华敏 陈红燕 贾东升 谢联辉 魏太云 | 2014 | 农业生物技术学报2014，22，11： | 5 |

| 7 | 水稻病毒与其宿主miRNAs相互作用的研究进展显示文摘miRNAs(micro RNAs)是真核生物中一类大小约为21 nt,并具有调控功能的非编码小分子单链RNA。miRNAs能够调控水稻基因的表达,对水稻的发育和生理机能至关重要。miRNA沉默途径可以抵御水稻病毒的入侵,减小病毒侵染带来的危害。然而,一些病毒也会编码各种针对miRNA沉默途径的沉默抑制子来对抗这种机制。于是,miRNAs和水稻病毒之间就形成了一种抑制与反抑制的动态平衡体系。现对水稻病毒与其宿主miRNAs之间的相互作用进行了系统的阐述,以期深入理解水稻病毒与宿主相互作用的机制并为水稻病害的防治提供新的思路与方法。 | 程青青 董兰兰 杨芳 张蕾 刘万红 | 2015 | 生命科学2015，27，10： | 0 |
