Candida albicans Agar Invasion Assays

[Abstract]  The ability of the human fungal pathogen Candida albicans to disseminate into tissues is promoted by a switch from budding to invasive hyphal growth. This morphological transition is stimulated by multiple environmental factors that can vary at different sites of infection. To identify genes that promote invasive growth, C. albicans mutants can be screened for defects in growing invasively into solid agar medium as a substitute for studying tissue invasion. This in vitro approach has advantages in that it permits the media conditions to be varied to mimic different ... [摘要]  [摘要 ] 人类真菌病原体白色念珠菌传播到组织的能力是由从发芽到侵入性菌丝生长的转换而增强的。多种环境因素可能会刺激这种形态转变,这些环境因素可能在不同的感染部位有所不同。为了鉴定促进侵入growt基因小时,白色念珠菌突变体可以在侵入性生长成固体琼脂培养基作为研究组织侵袭的替代品进行筛选的缺陷。这个体外 该方法的优点在于,它允许改变媒体条件以模仿不同的主机环境。另外,可以改变琼脂的浓度以确定改变细胞侵袭的基质的刚度的作用,因为与液体培养中形成菌丝的能力相比,这提供了更好的侵袭性生长指标。在多种条件下的测试可以用来鉴定具有最强缺陷的突变细胞。因此,将描述用于分析白色念珠菌在不同条件下的侵袭性生长的方案和培养基,其适合于测试突变株白色念珠菌菌株的单个菌株或高通量分析。

[背景 ] 白色念珠菌是一种多形性真菌病原体,可以通过形成芽(小球形细胞),假菌丝细胞(细长细胞链)或菌丝细胞(具有平行平行线的长丝状细胞链)生长(图1)(贵族等人,2017)。已证明宿主中遇到的多种环境刺激可促进向侵袭性生长的转变,包括人体温度(37 °C ),碱性pH,CO 2 ,血清中的因子和糖GlcNAc(N-乙酰氨基葡萄糖) )(Kornitzer,2019)。萌芽细胞被认为促进胃肠道的血流传播和定植(Pierce和Kumamoto ,2012 ;Witchley ...

[Abstract]  An important component of this methodology is to assess the role of the tumor microenvironment on tumor growth and survival. To tackle this problem, we have adapted the original approach of Warburg (Warburg, 1923), by combining thin tissue slices with Stable Isotope Resolved Metabolomics (SIRM) to determine detailed metabolic activity of human tissues. SIRM enables the tracing of metabolic transformations of source molecules such as glucose or glutamine over defined time periods, and is a requirement for detailed pathway tracing and flux analysis. In our approach, we maintain freshly resected ... [摘要]  这种方法的一个重要组成部分是评估肿瘤微环境对肿瘤生长和存活的作用。为了解决这个问题,我们采用Warburg(Warburg,1923)的原始方法,通过将薄组织切片与稳定同位素解析代谢组学(SIRM)组合来确定人体组织的详细代谢活性。 SIRM使得能够在定义的时间段内跟踪诸如葡萄糖或谷氨酰胺的来源分子的代谢转化,并且是详细的途径追踪和通量分析的要求。在我们的方法中,我们保持在细胞培养基中新鲜切除的组织切片(来自同一受试者的相同器官的癌性和非癌性),并用适当的稳定的富含同位素的营养物,例如葡萄糖或13 C 15葡萄糖或13 C 15葡萄糖或13 C 15葡萄糖, - 谷氨酰胺。这些切片可存活至少24小时,并使得有可能消除对靶组织代谢的系统影响,同时保持原始的3D细胞结构。因此,它是用于评估治疗剂对靶组织代谢的影响及其对个体患者的治疗功效的极好的临床前平台(Xie等人,2014; Sellers等人,/em>,2015)。
