Wounding Caenorhabditis elegans with Glass Wool

[Abstract]  

Research on wound healing majorly relies on rat, mice and other animal models. However, an alternative animal model ought to be brought in the field, pertaining to the stringent ethical issues owing to the use of animals in research. In this regard, Caenorhabdits elegans, a miniature model nematode gains the great attention of the researchers in wound healing. Though, the model is being explored in wound research for more than a decade, the existing protocols lack the acquisition of large wound population that in turn could enable the utility of global genomics (G), proteomics (P) and

[摘要]  [摘要] - [R上伤口愈合majorly esearch依赖于大鼠,小鼠和其它动物模型。但是,由于在研究中使用动物而引起的严格的伦理问题,应该在该领域引入一种替代的动物模型。在这方面,线虫微型模型线虫(Caenorhabdits elegans)在伤口愈合方面引起了研究人员的极大关注。虽然,该模型正在伤口研究中探索在过去的十多年中,现有协议缺乏获得大量伤口人口的能力,这反过来又可以使基于全球基因组学(G),蛋白质组学(P)和代谢组学(M)的方法得以实用。为了克服现有协议的不足,此处描述的协议使用截短的玻璃棉片提供了秀丽隐杆线虫中大量伤口种群的采集,以实现高通量分析技术的实用性。

Total Triglyceride Quantification in Caenorhabditis elegans

[Abstract]  Several studies suggest an important role of lipid metabolism in regulating longevity of Caenorhabditis elegans. Therefore, assays to quantify lipids have enormous value in understanding aging and pathologies associated with it. Approximately 70% of lipid metabolism genes in the nematode have orthologs in humans. Amenability of C. elegans to genetic manipulations has allowed investigations into the role of specific genetic factors in lipid metabolism. Here, we describe a protocol to quantify total triglycerides in C. elegans, which can be extended to studies of the ... [摘要]  [摘要]多项研究表明脂质代谢在调节秀丽隐杆线虫的寿命中具有重要作用。因此,定量脂质的测定在理解衰老和与其相关的病理学方面具有巨大价值。线虫中大约70%的脂质代谢基因在人类中具有直系同源物。秀丽隐杆线虫对基因操作的适应性允许调查特定遗传因素在脂质代谢中的作用。在这里,我们描述了一个协议,以定量总甘油三酯在秀丽隐杆线虫,这CA n可以扩展到环境和遗传因素改变对储存脂肪的影响的研究。该协议量化了整个蠕虫裂解物中甘油三酸酯的皮摩尔。由于测定的敏感性,它可以帮助鉴定总存储脂肪的细微变化,这是显微镜技术无法识别的。


[背景]多余的卡路里通常以三酰基甘油或糖原的形式存储(Cohen,2018年)。甘油三酸酯(TAGs)的异常水平与人类的心脏病,胰腺炎和动脉粥样硬化有关(Cameron等人,1974; Lee等人,2003; Walther和Farese,2012; Onal等人,2017)。TAG被包装到细胞质中的脂滴中。脂质液滴存在于真核细胞中,大小从20 nm到100 µm不等(Stobart等,1986; ...

Activation of Fibroblast Contractility via Cell-Cell Interactions and Soluble Signals

[Abstract]  The collagen contraction assay is an in vitro, three-dimensional method to determine the factor(s) affecting the contractile behavior of activated cells such as fibroblasts in either physiological or pathological scenarios. The collagen lattices/hydrogels are seeded with fibroblasts to mimic the interactions between these cells and their surrounding extracellular matrix proteins in the connective tissue. This method is an important platform to assess components as potential therapeutic targets to prevent pathologies such as fibrosis, which are manifestations of hyperactivated ... [摘要]  胶原收缩测定是体外三维方法,用于确定影响生理或病理场景中活化细胞如成纤维细胞的收缩行为的因子。 胶原蛋白晶格/水凝胶用成纤维细胞接种,以模拟这些细胞与其周围细胞外基质蛋白在结缔组织中的相互作用。 该方法是评估组分作为潜在治疗靶标的重要平台,以预防纤维化等病症,这些病症是过度活化的成纤维细胞的表现。 我们已经描述了这种胶原收缩测定的基本版本,其适于在不同实验条件下使用不同细胞类型进行定制。

【背景】细胞外基质的组织收缩和重塑是许多生理条件(例如伤口愈合)中的基本过程。这两种现象的核心是成纤维细胞,它不仅产生和分泌细胞外基质蛋白,而且还可以通过机械相互作用重组它们。有趣的是,这些细胞行为通常在诸如纤维化的病理条件下被夸大(Desmoulière et al。,2005),从而说明需要理解这些过程的分子调节。虽然人们早就知道,胶原蛋白是细胞外基质的主要成分之一,是组织收缩的主要参与者(Bell et al。,1979),对机械细节的透彻理解。这个过程仍然难以捉摸。对体外成纤维细胞胶原基质体外收缩的研究使研究人员能够识别导致组织收缩的新型运动员(Ngo et al。,2006; Su and Chen, 2015年)。基于该测定,可溶性因子如TGFβ(Levi-Schaffer 等,1999)和免疫细胞(Garbuzenko et al。,2002; ...
