, 2008 由于对真核生物基因转录延伸期研究的忽视,现有的真核生物基因转录理论存在种种的偏颇。然而,新近的研究发现却使人们逐渐认识到,真核基因转录延伸阶段其实是真核细胞调节基因转录的一个高度有序、而又极为复杂的调控平台。本文尝试对近年来真核生物基因转录延伸领域的研究进展,包括转录延伸与mRNA加工的偶联、基因转录延伸调控的分子机理以及转录延伸调控对发育和应激反应产生的影响 ...

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

De-ubiquitinating Enzyme A20 block HIV-1 gene transcription cooperatively activitated by HMBA and Prostratin [PDF]
, 2013 艾滋病之所以难治愈的一个关键问题，在于HIV病毒以潜伏状态存在于宿主细胞内，躲避药物的靶向作用。因此，激活潜伏的病毒，再让其暴露于药物之下，就可以有望杀死所有病毒从而治愈艾滋病。而激活潜伏状态的病毒，关键在于激活HIV-1基因的转录。我们将HIV-1启动子区域和荧光素酶报告基因形成融合基因转染HeLa细胞，建立稳定表达融合基因的细胞株。采用HMBA和Prostratin联合用药的处理方式，极大激活了HIV-1基因的转录，达到激活HIV-1的潜伏的目的。为了探索这两种药物协同激活HIV ...
