[Abstract]  Inositol triphosphate (IP3) is an important second messenger that participates in signal transduction pathways in diverse cell types including hippocampal neurons. Stimulation of phospholipase C in response to various stimuli (hormones, growth factors, neurotransmitters, neurotrophins, neuromodulators, odorants, light, etc.) results in hydrolysis of phosphatidylinositol 4, 5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, and leads to the production of IP3 and diacylglycerol. Binding of IP3 to the IP3 ... [摘要]  肌醇三磷酸(IP3)是参与信号转导途径的重要的第二信使,包括海马神经元在内的不同细胞类型。 刺激磷脂酶C对各种刺激(激素,生长因子,神经递质,神经营养因子,神经调节剂,气味剂,光等)的反应导致磷脂酰肌醇4,5-二磷酸(PIP2)的水解,磷脂位于质膜 ,并导致IP3和二酰基甘油的生产。 IP3与IP3受体(IP3R)的结合诱导Ca2 +从细胞内储存释放,并使细胞内Ca2 +依赖信号的启动。 在这里,我们描述了从大鼠海马切片制备的组织匀浆中测量细胞IP3水平的程序。

[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)。
