Research Progress on the Molecular Mechanisms of Toxicology of Ethanol-Aconitine Induced Arrhythmia [PDF]
, 2020 Aconitum is one of the most widely used Chinese herbal medicines, and aconitine is the major toxic component in it. Aconitine can induce a variety of arrhythmias, resulting in death. Acute ethanol consumption causes arrhythmia as well.

Zhongguo shiyan zhenduanxue, 2015 人乳头瘤病毒（HPV）通过表达病毒癌基因,干扰机体正常信号转导、细胞因子活化及扰乱有效的细胞免疫应答形成了癌症发病的确切因素,但此过程需要经历长期且极其复杂的系列分子事件和多种编码基因与非编码基因的参与,并且在不同的感染部位,致癌的几率和病理过程差异很大[1,2];近年来,随着微小RNA（miRNA）的基因表达调控网络的逐渐发现,miRNA在肿瘤的发生 ...

Study on The Mechanisms of HBXIP Promoting Invasion and Metastasis in Hepatocellular Carcinoma [PDF]
, 2017 第一部分HBXIP在HCC中高表达与病人恶性预后密切相关 本研究目的是观察在原发性肝癌中HBXIP的表达情况及相关的临床病理意义。通过用RT-PCR的方法对61对肝癌病人组织标本中癌组织与癌旁组织中HBXIP的mRNA表达情况，结果发现癌组织中HBXIP的mRNA水平明显高于癌旁组织(P=0.0009)。mRNA分析显示异常表达的HBXIP与肝癌病人的性别(P=0.031)、肿瘤转移(P=0.047）密切相关。肝癌组织中HBXIP的mRNA表达越高生存越差 ...

Identification of New Components Required for RNA Derected DNA Methylation in Arabidopsis thaliana [PDF]
, 2012 表观遗传学是近些年来人们比较关注的学科之一，和传统遗传学不同，它旨在研究：1基因如何发挥功能及基因间的互作关系；2研究范畴在于涉及DNA序列外，使基因表达模式发生改变并可使之在世代间稳定遗传的因素。其中基因沉默是表观遗传学表现形式之一，基因沉默所讨论的是：一种分子生物学上由双链RNA诱发的基因不表达现象，其机制是通过阻碍特定基因的翻译或转录来抑制基因表达。通常意义下，根据沉默发生时期的不同将基因沉默分作两大类：转录水平的基因沉默和转录后水平的基因沉默 ...

, 2005 RNA干扰(RNAi)是目前分析基因组功能及基因治疗的一个有力工具,引起基因沉默现象的小干扰RNA(siRNA)需要经过适当的化学修饰才能应用于体内。该文总结了既能稳定siRNA双链,又能有效抑制靶基因的几种常用化学修饰法,包括磷酸骨架修饰、核糖修饰和碱基修饰等。正确的修饰将会极大地促进RNAi药物从体外到体内、从实验室到临床应用的转化。siRNA作为一种很有潜力的药物将为治疗病毒性疾病、肿瘤和遗传病开辟一条崭新的道路 ...
