Schulze C, Smales C, Rubin LL, Staddon JM. prostanoids, epoxyeicosatrienoic acids, sphingolipids, and lysophospholipids, contribute to vascular function and signaling within the endothelium. Methods for quantifying lipids will be briefly discussed, followed by an overview of the various lipid families. The cross talk in signaling between classes of lipids will be discussed in the context of vascular disease. Finally, the potential clinical implications of these lipid families will be highlighted. double bonds of arachidonic acid allow it to react with three oxygenases to form different subtypes of eicosanoids, including prostaglandins, epoxyeicosatrienoic acids, and leukotrienes. Therefore, while methods that do not require lipid extraction may result in higher yield, these methods often lack specificity to distinguish between isoforms within the same lipid family. For these reasons, the method of choice for lipid measurement should be chosen on the basis of the specific question being addressed. Some of the earliest bioassays for lipid quantification relied on comparison of biological activity with the assumption that activity was directly correlated to concentration (147). These results were expressed as lipid-equivalent levels. Unfortunately, this methodology does not take into account volume of distribution, activity, and degree of metabolite development, binding affinity, and membrane permeability, each which needs to be looked at for precise dimension. Highly relevant to the scholarly research from the microcirculation, newer strategies have already been created that on radiolabeling rely, fluorescence recognition, and dimension of absorbance (colorimetric assays) to quantify lipids appealing. While these procedures will never be evaluated right here thoroughly, brief explanations, aswell as pitfalls and advancements, for each of the strategies will be described below and so are summarized in Desk 1 briefly. The reader thinking about a more comprehensive explanation of advantages and weaknesses of the assays is described several superb citations (1, 61, 86, 99, 145). Desk 1.
