[Abstract]  E. coli resides in the gastrointestinal tract of humans and other warm-blooded animals but recent studies have shown that E. coli can persist and grow in various external environments including soil. The general stress response regulator, RpoS, helps E. coli overcome various stresses, however its role in soil survival was unknown. This soil survival assay protocol was developed and used to determine the role of the general stress response regulator, RpoS, in the survival of E. coli in soil. Using this soil survival assay, we demonstrated that RpoS was ... [摘要]  电子。 大肠杆菌位于人类和其他温血动物的胃肠道中,但最近的研究表明,E。 大肠杆菌可以在包括土壤在内的各种外部环境中持续生长。 一般的压力响应调节器RpoS有助于E。 克隆各种压力,但其在土壤中的作用尚不清楚。 开发了这种土壤生存测定方案,并用于确定一般应激反应调节剂RpoS在E的存活中的作用。 大肠杆菌在土壤中。 使用这种土壤生存测定,我们证明RpoS对于E的生存是重要的。 大肠杆菌在土壤中。 该方案描述了土壤生存测定的发展,特别是E的恢复。 大肠杆菌接种到土壤中,可适应于进一步研究土壤中其他细菌的存活。
【背景】大肠杆菌是属于肠杆菌科的革兰氏阴性兼性厌氧菌,其栖息于人类的肠道,温血动物和爬行动物(Berg,1996; Gordon和Cowling,2003)。可通过粪便通过水和沉淀物进行转运,并用作饮用水和娱乐用水中粪便污染的指标。使用 E。大肠杆菌作为粪便指标至少部分地基于其临时存在于主体胃肠道之外的假设(Ishii和Sadowsky,2008),并且在外部环境中长时间不存活。然而,一些研究已经分离出E。来自各种自然环境的大肠杆菌,例如城市废水,淡水,沙滩水,海滩沙土和土壤(Jiménez等人,1989; Brennan等人, 2010; Chiang等人,2011; Byappanahalli等人,2012; ...

Flow Cytometric Analysis of HIV-1 Transcriptional Activity in Response to shRNA Knockdown in A2 and A72 J-Lat Cell Lines

[Abstract]  The main obstacle to eradicating HIV-1 from patients is post-integration latency (Finzi et al., 1999). Antiretroviral treatments target only actively replicating virus, while latent infections that have low or no transcriptional activity remain untreated (Sedaghat et al., 2007). To eliminate viral reservoirs, one strategy focuses on reversing HIV-1 latency via ‘shock and kill’ (Deeks, 2012). The basis of this strategy is to overcome the molecular mechanisms of HIV-1 latency by therapeutically inducing viral gene and protein expression under antiretroviral therapy and to ... [摘要]  消除HIV-1患者的主要障碍是后整合延迟(Finzi等人,1999)。抗逆转录病毒治疗仅针对主动复制病毒,而具有低转录活性或无转录活性的潜伏感染仍未得到治疗(Sedaghat等人,2007)。为了消除病毒性水库,一项战略重点是通过“休克和杀死”来逆转HIV-1潜伏期(Deeks,2012)。该策略的基础是通过在抗逆转录病毒治疗下通过治疗性诱导病毒基因和蛋白质表达来克服HIV-1潜伏期的分子机制,并通过病毒的溶解性质或现在识别感染细胞的免疫系统引起选择性细胞死亡。最近,许多研究已经描述了药物抑制人类溴结构域蛋白质的溴结构域和末端(BET)家族的成员的治疗潜力(Filippakopoulos等人,2010; Dawson等人& / em>,2011; Delmore等人,2011),其包括BRD2,BRB3,BRD4和BRDT。小分子BET抑制剂,例如JQ1(Filippakopoulos et al。,2010; Delmore等人,2011),I-BET(Nicodeme等人< / ...
