Ex vivo Trophoblast-specific Genetic Manipulation Using Lentiviral Delivery

[Abstract]  In this protocol report, we describe a lentiviral gene delivery technique for genetic modification of the rat trophoblast cell lineage. Lentiviral packaged gene constructs can be efficiently and specifically delivered to the trophoblast cell lineage of the blastocyst. The consequences of ‘gain-of-function’ and ‘loss-of-function’ blastocyst manipulations can be evaluated with in vitro outgrowth assays or following transfer to pseudopregnant rats. [摘要]  在这个协议报告中,我们描述了一种慢病毒基因传递技术的基因修改大鼠滋养细胞谱系。 慢病毒包装的基因构建体可以有效地和特异性地递送至胚泡的滋养层细胞谱系。 “功能获得”和“功能丧失”囊胚操作的后果可以用体外生长测定或转移到假孕大鼠后进行评估。

【背景】胎盘作为母亲和发育中的胎儿之间的通道,对于胎儿生殖是必不可少的(Georgiades et。,<2002>)。它是专门用于促进和协调母体对妊娠和胎儿发育的适应性(Soares等人,2014; Burton等人,2016)。胎盘含有滋养层细胞,它们执行多种特殊功能。滋养层细胞特化的获得需要高度调控的滋养层干细胞和祖细胞群的分化(Maltepe and Fisher,2015)。成熟的大鼠胎盘由两个形态上和功能上不同的区室组成:交界区和迷宫区(Soares等人,2012)。祖细胞,海绵状滋养层细胞,糖原滋养层细胞和多倍体滋养层巨细胞构成交界区。侵入性滋养层谱系来自交界区内的祖细胞(Ain等人,2003; Soares等人,2014)。在妊娠的最后一周,这些细胞移出胎盘并侵入母体子宫隔膜室(Ain等人,2003; ...

Reconstruction of the Mouse Inflammasome System in HEK293T Cells

[Abstract]  The NLRP3 (NLR family, Pyrin domain containing 3) inflammasome is a multiprotein complex comprised of NLRP3, pro-caspase-1, the adaptor protein apoptosis-associated speck-like protein containing a CARD (ASC), and the protein kinase NIMA related kinase 7 (NEK7) (Shi et al., 2016; He et al., 2016; Schmid-Burgk et al., 2016). When cells are exposed to microbes and/or danger signals, the inflammasome assembles and serves as a platform for the activation of caspase-1. Caspase-1 activation promotes the processing and secretion of the pro-inflammatory cytokines ... [摘要]  核糖体足迹或Ribo-seq,彻底改变了翻译研究。它最初是为培养中的酵母和哺乳动物细胞开发的(Ingolia等人,2009)。本文中,我们描述了来自先前公开的多核糖体分离程序的植物优化的亲手核糖体印迹方案(Ingolia等人,2009; Mustroph等人,2009 )和核糖体印迹(Ingolia等人,2009; Ingolia等人,2013)。使用该协议,我们能够成功地分离和分析来自体外生长的拟南芥植物(黑暗生长的幼苗)的不同阶段的高质量核糖体印迹[Merchante < ,以及在液体培养物中生长的板和植物中的13天龄小植物[未发表的结果])。

[背景] 翻译在调节基因活性中的中心作用早已被公认,但是在响应于特定刺激的全基因组翻译定量变化的系统探索最近才变得技术上可行。最初为培养中的酵母和哺乳动物细胞开发的核糖体印迹技术(通常称为Ribo-seq)已经彻底改变了翻译调节和基因表达的研究,因为其允许确定核糖体在基因组 - ...
