| 1 | circRNA研究现状及展望显示文摘circRNA(Circular RNAs)是一类不具有5′末端帽子和3′末端poly(A)尾巴并以共价键形成封闭环状结构的内源性非编码RNA(nc RNA)分子,根据circ RNA的剪接来源不同,可分为外显子circ RNA(Exonic cir RNAs)、内含子circ RNA(cir RNAs)和外显子—内含子circ RNA(Exon-in-troncirc RNA,EIci RNA)。文章从分子特征、研究历程、形成过程、作用机制及其数据库及分析工具等方面对circ RNA研究现状和生物学功能进行综述,结果显示随着高通量测序技术的进步和生物信息学的快速发展,越来越多的circ RNA被挖掘,其具有稳定性、广泛性、保守性及组织特异性等性质,在基因表达调控中发挥重要作用,可作为一种疾病的生物标志物,在临床诊断和治疗方面具有广阔的应用前景。但circ RNA还有许多尚未知悉的重要生物学功能,如其在绒毛生长发育中的作用机理,且在疾病诊断和治疗方面研究不够深入。在今后研究中,应深入研究circ RNA及其在疾病诊断、治疗方面及绒毛发育的作用机制,充分了解其更多的生物学功能,使其广泛应用于各研究领域。 | 王宏浩 韩文静 张燕军 苏蕊 刘志红 王瑞军 王志英 赵艳红 王志新 李金泉 | 2018 | 南方农业学报2018，49，3： | 5 |

| 4 | Mutual dependency between lncRNA LETN and protein NPM1 in controlling the nucleolar structure and functions sustaining cell proliferation显示文摘Fundamental processes such as ribosomal RNA synthesis and chromatin remodeling take place in the nucleolus,which is hyperactive in fast-proliferating cells.The sophisticated regulatory mechanism underlying the dynamic nucleolar structure and functions is yet to be fully explored.The present study uncovers the mutual functional dependency between a previously uncharacterized human long non-coding RNA,which we renamed LETN,and a key nucleolar protein,NPM1.Specifically,being upregulated in multiple types of cancer,LETN resides in the nucleolus via direct binding with NPM1.LETN plays a critical role in facilitating the formation of NPM1 pentamers,which are essential building blocks of the nucleolar granular component and control the nucleolar functions.Repression of LETN or NPM1 led to similar and profound changes of the nucleolar morphology and arrest of the nucleolar functions,which led to proliferation inhibition of human cancer cells and neural progenitor cells.Interestingly,this inter-dependency between LETN and NPM1 is associated with the evolutionarily new variations of NPM1 and the coincidental emergence of LETN in higher primates.We propose that this human-specific protein–lncRNA axis renders an additional yet critical layer of regulation with high physiological relevance in both cancerous and normal developmental processes that require hyperactive nucleoli. | Xianteng Wang Xiaolin Hu Wanlu Song Hui Xu Zhengtao Xiao Rongyao Huang Qingran Bai Fan Zhang Yongzhen Chen Yu Liu Jianhuo Fang Xin Li Qin Shen Haitao Zhao Xuerui Yang | 2021 | Cell Research2021，31，6： | 3 |
| 5 | RNA modifications:importance in immune cell biology and related diseases显示文摘RNA modifications have become hot topics recently.By influencing RNA processes,including generation,transportation,function,and metabolization,they act as critical regulators of cell biology.The immune cell abnormality in human diseases is also a research focus and progressing rapidly these years.Studies have demonstrated that RNA modifications participate in the multiple biological processes of immune cells,including development,differentiation,activation,migration,and polarization,thereby modulating the immune responses and are involved in some immune related diseases.In this review,we present existing knowledge of the biological functions and underlying mechanisms of RNA modifications,including N6-methyladenosine(m^(6)A),5-methylcytosine(m^(5)C),N1-methyladenosine(m1 A),N7-methylguanosine(m^(7)G),N4-acetylcytosine(ac^(4)C),pseudouridine(Ψ),uridylation,and adenosine-to-inosine(A-to-I)RNA editing,and summarize their critical roles in immune cell biology.Via regulating the biological processes of immune cells,RNA modifications can participate in the pathogenesis of immune related diseases,such as cancers,infection,inflammatory and autoimmune diseases.We further highlight the challenges and future directions based on the existing knowledge.All in all,this review will provide helpful knowledge as well as novel ideas for the researchers in this area. | Lian Cui Rui Ma Jiangluyi Cai Chunyuan Guo Zeyu Chen Lingling Yao Yuanyuan Wang Rui Fan Xin Wang Yuling Shi | 2022 | Signal Transduction and Targeted Therapy2022，7，10： | 2 |
| 6 | RNA特异性腺苷脱氨酶的生物学作用及其与人类疾病的关系显示文摘RNA编辑(尤其是A-to-I RNA编辑)是哺乳动物常见的转录后修饰方式。RNA特异性腺苷脱氨酶(adenosine deaminase acting on RNA,ADAR)是A-to-I编辑的关键蛋白,它通过脱氨基作用使双链RNA中的腺苷基团转化为肌酐基团,从而导致核苷酸序列改变。目前已发现的ADARs共有3类(ADAR1,ADAR2,ADAR3),它们的异常与众多人类疾病密切相关,如病毒感染、代谢性疾病、神经系统疾病、肿瘤等。 | 陈柯竹 麻茹则 王芳 | 2018 | 中南大学学报(医学版)2018，43，8： | 1 |
| 7 | The RNA editome of Macaca mulatta and functional characterization of RNA editing in mitochondria显示文摘RNA editing was first discovered in mitochondrial RNA molecular. However, whether adenosine-toinosine(A-to-I) RNA editing has functions in nuclear genes involved in mitochondria remains elusive.Here, we retrieved 707,246 A-to-I RNA editing sites in Macaca mulatta leveraging massive transcriptomes of 30 different tissues and genomes of nine tissues, together with the reported data, and found that A-to-I RNA editing occurred frequently in nuclear genes that have functions in mitochondria. The mitochondrial structure, the level of ATP production, and the expression of some key genes involved in mitochondrial function were dysregulated after knocking down the expression of ADAR1 and ADAR2, the key genes encoding the enzyme responsible for RNA editing. When investigating dynamic changes of RNA editing during brain development, an amino-acid-changing RNA editing site(I234/V) in MFN1, a mediator of mitochondrial fusion, was identified to be significantly correlated with age, and could influence the function of MFN1. When studying transcriptomes of brain disorder, we found that dysregulated RNA editing sites in autism were also enriched within genes having mitochondrial functions. These data indicated that RNA editing had a significant function in mitochondria via their influence on nuclear genes. | Ling-Qun Ye Hui Zhao He-JiangZhou Xiao-Die Ren Lin-Lin Liu Newton O.Otecko Zheng-boWang Min-Min Yang Lin Zeng Xin-Tian Hu Yong-Gang Yao Ya-Ping Zhang Dong-Dong Wu | 2017 | Science Bulletin2017，62，12： | 1 |

| 9 | RNA结合蛋白在多能干细胞命运转变中的研究进展显示文摘RNA结合蛋白(RNA binding proteins,RBPs)是一类通过其RNA结合结构域与RNA相互作用的蛋白质,在细胞内发挥着非常重要的作用。RBPs参与从RNA代谢(包括RNA的可变剪接、稳定性、翻译)到表观遗传修饰等多种调控途径。已有大量文献报道转录因子、表观遗传修饰和细胞外信号通路参与调控干细胞的多能性维持、分化和体细胞重编程,但对于RBPs在细胞命运转变中作用的研究报道甚少。该文主要综述了RBPs通过调控RNA的可变剪接、mRNA稳定性、翻译水平、microRNA代谢及组蛋白修饰进而调控干细胞多能性维持和体细胞重编程。 | 王秀芹 尹梦然 夏晴 王丽莎 秦宝明 姚红杰 | 2020 | 中国细胞生物学学报2020，42，1： | 0 |
