[Abstract]  Programmed cell death (PCD) guides the transition between key developmental stages in many organisms. PCD also remains an important fate for many organisms upon exposure to different stress conditions. Therefore, an insight into the progression of PCD during the execution of a biological phenomenon can yield significant details of the underlying mechanism. Apoptosis, as well as apoptosis-like programmed cell death, constitutes one of the forms of PCD in higher and lower eukaryotes respectively. Flipping of phosphatidylserine (PS) from the inner leaflet of the plasma membrane to the outer ... [摘要]  程序性细胞死亡(PCD)指导许多生物体的关键发育阶段之间的过渡。 PCD在暴露于不同的胁迫条件下仍然是许多生物的重要命运。因此,在执行生物现象期间洞察PCD的进展可以产生潜在机制的重要细节。细胞凋亡以及凋亡样程序性细胞死亡分别构成高等和低等真核生物中PCD的一种形式。将磷脂酰丝氨酸(PS)从质膜的内部小叶翻转到外部小叶是凋亡/凋亡样PCD的不同标志之一,其标志着所述细胞死亡事件的开始。可以使用与PS特异性结合的膜联蛋白V-FITC通过染色靶细胞来检测这种翻转。在 Ustilago maydis 中,由于细胞壁的存在,膜联蛋白V-FITC对外露PS的染色是困难的。因此,这种染色的关键在于,在不显着改变下面的质膜结构/拓扑结构的情况下,温和地去除细胞壁。该协议强调了PS染色对 Ustilago maydis 中应激细胞原生质体的依赖性。

【背景】PS外化是早期可以检测到的凋亡样PCD的标志之一(Martin et al。,1995)。因此,质膜在细胞外膜上的出现标志着凋亡细胞死亡现象的发生。 Ustilago maydis 是一种生物营养植物病原体并感染寄主植物 Zea mays 。 U的生命周期。已证明maydis ...

DNA in situ Hybridizations for VEGFA Gene Locus (6p12) in Human Tumor Tissue

[Abstract]  Over the last decades numerous regulators of angiogenesis have been identified and characterized. Among the others the vascular endothelial growth factor (VEGFA) appears undoubtedly important in several pathophysiological processes. Moreover, VEGFA represents one of the most attractive targets of anticancer therapy, given its major role in the growth and development of different tumor types. Here we describe a method to detect the copy number variation (CNV) status of the VEGFA gene by fluorescence in situ hybridization (FISH). FISH analysis is a reliable method for investigating ... [摘要]  在过去的几十年中,已经鉴定和表征了许多血管生成的调节剂。 其中血管内皮生长因子(VEGFA)在几种病理生理过程中无疑是重要的。 此外,VEGFA代表抗癌治疗的最有吸引力的靶标之一,因为其在不同肿瘤类型的生长和发展中的主要作用。 在这里我们描述了通过荧光原位杂交(FISH)检测VEGFA基因的拷贝数变异(CNV)状态的方法。 FISH分析是用于研究VEGFA扩增或增加的基因拷贝数的可靠方法,并且可以代表用于研究VEGFA表达水平的失调的免疫组织化学分析的替代方法。
