One can thus follow the fate of a certain nutrient and determine the predominant metabolic pathway. Individuals with PTSD have been shown to have problems with these types of memory, using both neuropsychological tests (such as the Wechsler Memory Scale, the visual and verbal components of the Selective Reminding Test, the Auditory Verbal Learning Test, Paired Associate Recall, the California Verbal New Learning Test, and the Rivermead Behavioral Memory Test; Bremner, 2008) and virtual reality tasks such as a virtual water maze (Astur et al., in review; see Figure 5.2). 7). This type is found in straight-nosed pipefish (genus Nerophis), sea dragons (genus Phyllopteryx) and fragtail pipefish (genus Doryrhamphus). XF96 Cell Culture Microplate (Seahorse Bioscience Inc., Billerica, MA, USA); store at room temperature. 7 is useful. 3) takes place with higher and higher respiratory rates (and sulfide oxidation) ending abruptly when sulfide is exhausted. The “Seahorse” technology has become very popular to measure cellular respiration and to evaluate lactate release. Brood pouch types are shown with increasing complexity within the Urophori and Gastrophori. The sensor cartridges contain solid state sensor probes for detecting oxygen and proton levels in cell culture media. The brooding structure of the Urophori is located on the tail, and that of the Gastrophori is on the abdomen. Finally, the pouch folds are formed, ready to incubate embryos. I am running a Seahorse assay (Glyclolysis test) on cKIT+ cells from murine bone marrow. 9). (A) Before the uptake of eggs and (B) after the uptake of eggs from female. Finally, respiration resumes indicating that sulfide has been consumed. The Agilent Seahorse XF Real-Time ATP rate assay allows you to measure what matters. Recent molecular analysis showed that Apolipoprotein M genes involved in lipid transport are expressed in the brood pouch during pregnancy. 3. Ascorbic acid-2-phosphate (Sigma–Aldrich Corp., A-8960); store at 4 °C. Fig. Another 500 μL DPBS is added to a single well and cells are resuspended by pipetting up and down vigorously—the cell suspension is then transferred to obtain cells from another well and this process is repeated until cells from an entire plate have been collected. glycolysis and mitochondrial respiration simultaneously in live cells I am on a SeaHorse F24 assay with fibroblasts harbouring a mutation that affects mitochondrial functions. Seahorse birth is even more of a mystery than seahorse pregnancy, and we were excited to find that some of those 3,000 genes also prepare the father and the embryos for labour. Seahorse™ Normalization Assay at a Glance Simple Workflow for Seahorse™ Normalization Assay In recent years, Celigo Image Cytometer has been used to perform bright field or fluorescence-based … Third, in the presence of rotenone (bottom graph), a short sequence of accelerating oxygen consumption rate followed by an abrupt return to zero (flat line for oxygen value) indicates a period of a sulfide-based respiration, and the comparison with the injection steps in Fig. Detect changes in metabolic function in real time, providing a window on the earliest events of metabolic switching. Your access has now expired. Bovine serum albumin (A802, Sigma–Aldrich Corp.); store at 4 °C. 4. Differentiation of brood-pouch tissue begins, and the pseudoplacenta first appears on the dorsal side of the pouch. 2. Interestingly, based on recent molecular studies, genes involved in these functions of brood pouch are commonly expressed in female internally-gestating fish and also in viviparous amniotes (Whittington et al., 2015). Seahorse Food: The most interesting thing about seahorses is the astonishing fact that they don’t have a stomach. Fig. Predict the ability of somatic cell reprogramming to iPSCs, and understand how PSCs alter their metabolism during the differentiation process to terminally differentiated cells. Seahorses range in size—from as small as a pine nut to as large as a banana. The female fish deposits eggs into this brood pouch, and fertilization occurs immediately. Because Seahorse XF measurements are non-destructive, Page 34 Assay Wizard: Used to generate new assay templates or modify existing templates for assay design. Areas in the brain associated with stress, fear, and PTSD. Therefore, we advise to use RPMI medium without d-glucose and l-glutamine (Biological Industries), supplemented as usual with antibiotics, HEPES and β-mercaptoethanol, and with 10% dialyzed serum (Gibco). The brood pouch has an entrance to receive the eggs from female fish and for parturition. Accordingly, to record possible sulfide oxidation rate of cells in the Seahorse, we used the following modified procedure. Cellular oxygen consumption (respiration) and proton excretion (glycolysis) cause rapid, easily measurable changes to the concentrations of dissolved oxygen and free protons in this "transient microchamber" which are measured every few seconds by solid state sensor probes residing 200 microns above the cell monolayer. In the bottom graph, the first injection step added rotenone (1 μM final) in addition to sulfide. Browse some of the latest resources to help you enhance your research. 4 Institute for Diabetes and Obesity, Helmholtz Zentrum München, German Research Center for Environmental Health, Neuherberg, Germany. Seahorse XF Analyzers measure oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) of live cells in a multi-well plate, interrogating key cellular functions such as mitochondrial respiration and glycolysis. Three single steps of 30 min of measuring time are used: one before any injection (normal cellular respiration) and the two other after the first and the second injection of a sulfide solution (injections 1 and 2) leading to a theoretical final concentration of 250 μM Na2S. The pseudoplacenta entirely surrounds the pouch. This evidence suggests that patrotrophy might occur in seahorses by providing histotroph (Whittington et al., 2015). Numerous studies show that mitochondrial energy generation determines the effectiveness of immune responses. The Seahorse XF instrument was developed as a multi-well plate-based assay platform that uses fluorescent optode detectors to measure oxygen consumption rates (OCR) and extracellular acid … Fig. It is therefore unrealistic to envisage that sulfide would be added from the beginning. The projections become fused at the body midline. 4 (cited from Wilson et al., 2003). For more information on choosing the assay that is right for you, visit our. The pellet is then resuspended in the 13-C-containing labeling medium and cultured at 37 °C for several hours depending the 13-C substrate and on which metabolic flux is under investigation. First, we load the injection ports with a 10 × solution of sulfide leading to final concentration of 0.1–1 mM, far too concentrated when compared to the classical experiments and if actually present expected to inhibit severely the cellular respiration. α-Monothioglycerol (207-09232, WAKO Pure Chemical Industries); store at 4 °C. (3) In the most complicated case a baggy structure is used to incubate the eggs. Aspirate the media and replace it with 675 μl 37 °C Seahorse assay DMEM and proceed as quickly as possible with loading the plate into the XF analyzer and initiating the assay. They eat for the most of the time, as they … Studies with animals and humans reveal that the hippocampus is critical for memory, particularly for storing new memories in long-term memory (“encoding”) and recalling them (“retrieval”) when they involve language (“verbal” or “declarative” memory), environmental contexts (“contextual” memory), or visual perception of three-dimensional environments (“spatial” memory). Cells grown to roughly 80% confluence on Seahorse or Corning microplates are washed by adding 500 μL DPBS to the 200 μL growth medium in each well and removing 650 μL, leaving a notional volume of 50 μL. XF Calibrant, pH 7.4 (100840-000, Seahorse Bioscience Inc., Billerica, MA, USA); store at 4 °C. Cellular sulfide oxidation with the Seahorse. Real-time measurements of OCR and ECAR are made by isolating an extremely small volume (about 2 μL) of medium above a monolayer of cells within a microplate. Therefore, when the concentration is made low enough to allow respiration, and sulfide oxidation to resume, the positive feedback sequence of events (Fig. Mathias Wenes, ... Lianjun Zhang, in Methods in Enzymology, 2020. The extraction of an absolute rate of oxygen (and sulfide) consumption appears somehow complicate because the sulfide content of the measuring chambers does not allow more than a few data points to represent the sulfide oxidation phase, which moreover is expected to take place with a highly variable rate (consider the similar sequence of events as shown after the second injection in the top trace of Fig. Vascular endothelial growth factor (VEGFA) (Pepro Tech Inc.); store at − 80 °C. This assay provides insight into the cause of mitochondrial … Automatic measurement of energy metabolism in real time Seahorse XF Analyzers measure oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) of live cells in a multi-well plate, … Thank you for taking us up on our offer of free access to JoVE Education until June 15th. Figure 5.2. (1) In the simplest case, the structure is such that eggs are attached to the surface of the ventral side of the male body either with only mucous or within membranous compartments of the male body. Seahorse also manufactures consumable labware products, and consumables … We used the Seahorse XF assay to determine the bioenergetic responses of astrocytes cultured in NG and HG conditions. The specific function of the hippocampus is suggested by findings that visual memory and overall intellectual functioning (which are not specifically related to the hippocampus, although it may have some indirect roles in those functions) do not tend to be impaired in PTSD. Not for use in diagnostic procedures. They provide sensitive, kinetic measurements to simultaneously analyze the two main metabolic energy pathways: mitochondrial respiration and glycolysis. Fresh samples collected from the same donors will be compared with the frozen cells by simultaneously performing the bioenergetic assay using the Seahorse Bioscience XF Analyzer. Martin Pelletier, ... Richard M. Siegel, in Methods in Enzymology, 2014, Add 200 μL of Seahorse Bioscience calibrant pH 7.4 to each well of a Seahorse Bioscience 96-well utility plate.2, Place sensor cartridge on top of the utility plate and store at 37 °C without CO2 overnight.3, Turn on instrument and start XF software to allow instrument to stabilize at 37 °C.4.

Sheila Collins, in Methods in Enzymology, 2014. The MTT assay is done to evaluate the cell viability of all cells in culture, namely, the peripheral blood mononuclear cells (PBMCs)-derived monocytes, BMVECs, and NHAs. Measure the rate of ATP production from After being allowed to cool down for 2 min, samples are divided into 25 μL aliquots (1.4 × 105 cells each) that can be used for analysis immediately or may be stored at − 80 °C for at least several weeks. Pooled cells are harvested and counted in DPBS following a 5-min spin at maximum speed in a microfuge. Now you can measure the rate of ATP production from the two key energy pathways (glycolysis and mitochondrial … Vago, ... L.S. Contact us to learn more about our full range of ADME, PK and toxicity services for the pharmaceutical, cosmetics, personal care and chemical industries - high quality robust data Finally, the T cells are then collected, centrifuged and washed once with ice-cold saline. Similarly, care should be taken when adding media. It has been considered part of the limbic system and plays an important role in explicit, episodic, declarative, contextual, or relational forms of rapid encoding, consolidation, and retrieval processes related to memory and emotion. Some cells do not tolerate the absence of serum or other supplements very well, in which case it is necessary to experiment with adding these back at the lowest possible concentration to avoid interference with the assay. In order to more precisely map which nutrient is involved in specific metabolic fluxes and to which extent it gets incorporated in certain cellular metabolites, a 13-C metabolic flux analysis should be executed. A further complicating factor is the fact that the time needed to get one value of respiratory rate is relatively long and particularly because equilibration and mixing times are also to be considered. Although viviparous female fish species supply nutrients to embryos during pregnancy, paternal nutrition transfer (patrotrophy) in seahorses is somewhat equivocal. Seahorse XF FluxPaks include sensor cartridges, tissue culture plates, calibrant, and utility plates for performing calibration. They also have integrated injection ports for introduction of stimuli, inhibitors, and substrates during the assay which enables monitoring transient cellular responses in real time. 3 Seahorse Bioscience, Billerica, Massachusetts, USA. The machine was calibrated and the assay was performed using glycolytic stress test assay protocol as suggested by the manufacturer (Seahorse Bioscience, Billerica, MA, USA). Evolution of syngnathid fishes. Interestingly, the brooding structure has diverged during evolution as summarized in Fig. Add 40 μL of NaHCO3 0.1 M (pH 8.0) per well to neutralize and promote adsorption of Cell-Tak to the plate. Wash the cells with 1 ml unbuffered Seahorse assay DMEM heated to 37 °C. Designing these protocols and detecting the metabolites by mass spectrometry requires expert knowledge and is thus generally performed in collaboration with metabolomics experts. The Seahorse XF Assay Learning Center provides protocols, techniques and resources aligned to each step of the XF workflow to ensure optimal assay performance and results. Jonathan Barlow, ... Charles Affourtit, in Methods in Enzymology, 2013. 1: Glycolate supplementation rescues mitochondrial membrane potential and counteracts oxidative stress of paraquat-treated worms through a glutathione-dependent mechanism. For example, at the end of pregnancy in eutherian mammals, activation of the mitogen-activated protein kinase (MAPK) signaling pathway is suggested to be involved in parturition. The pouch formation was initiated from linear projections of epithelia on both ventrolateral sides of the body. A low micrometer solution of sulfide at physiological pH would hardly be stable during equilibration and mixing time. PMID: … Isoproterenol (12760, Sigma–Aldrich Corp.). Technical support is available and ready to assist. 1:100 Synthetic lipids (Gibco # 11905-031, Life Technologies, Inc.); store at 4 °C. The hippocampus is a small seahorse-shaped brain area that has been shown to be damaged in studies of animals that are exposed to chronic stressors (Bremner, 2008). By directly measuring the extracellular acidification rate, … Representatives are available to demonstrate how Agilent Seahorse XF Analyzers can solve your research needs. This type is found in seahorses (genus Hippocampus). These differences in brooding structures also affect the structures of eggs. The skin fold covers the eggs either partially, as found in the genus Corythoichthys, or completely, as found in some forms such as the deep-body pipefish (genus Kaupus) and pipefishes (genus Syngnathus). The 13-C metabolite then needs to be precisely weighed and added at the same molarity as the normal growth medium. Measuring Energy Pathways with the Seahorse XF Analyzer 19 November 2014 Watch this video to learn how the Seahorse XF Analyzer simultaneously measures mitochondrial respiration and glycoloysis via … Population data for most of the world’s more than 30 seahorse species is sparse. OCR and ECAR rates are key indicators of mitochondrial respiration and glycolysis and these measurements provide a systems-level view of cellular metabolic function in cultured cells and ex-vivo samples. Furthermore, changes in mitochondrial function may regulate … Then, brood-pouch specific tissues such as pseudoplacenta differentiated, and finally, a pouch-fold ready to incubate embryos was developed in the fully formed brood pouch (Fig. Interior of the seahorse brood pouch. 2 mM Glutamax II (Gibco #35050-061, Life Technologies, Inc.); store at − 20 °C. As said before (in Section 4.3) even in conditions of extreme inhibition, the sulfide concentration declines. Automatic measurement of energy metabolism in real time. Incubate overnight in a normal incubator set at 37 °C.7, Julian D. Ford, ... Christine A. Courtois, in Posttraumatic Stress Disorder (Second Edition), 2015. Seahorse Real-Time Cell Metabolic Analysis With over 20,000 genes, 200,000 proteins and thousands of pathways, you can't measure everything in a cell at once, but you can measure the energy that drives them… The largest seahorse species (pictured here) is Hippocampus abdominalis, or the big-bellied seahorse, which can reach … The difficulties stem from the fact that the measuring Seahorse plate remains essentially open to the outer atmosphere. Seahorse Bioscience is a private company that develops and manufactures cellular bioenergetics analytical instruments. Cell viability is also tested in the … In the presence of rotenone, a sharp increase in oxygen consumption followed by return to a zero rate is observed. Syngnathid fishes including seahorses, all of which possess the brooding area, commonly possess an elongated body with a series of bony rings and no pelvic fin (Nelson et al., 2016). This medium should be ideally devoid of the 12-C isotope of the metabolite under investigation. The egg envelope of seahorses is thinner than that of the messmate pipefish (covered with pouch folds) or the alligator pipefish (simple form of the brooding structure). The Seahorse XF Cell Mito Stress Test is the gold standard assay and is widely used for measuring mitochondrial function in cells. Specialized cell culture plates have been designed for spheroids and islets. Scale bar=1 mm. The CHO cells used in this “Seahorse” experiment are the same as in Fig. We use cookies to help provide and enhance our service and tailor content and ads. Introduction 6 Glossary 8 The Agilent Seahorse XF Glycolysis Stress Test is the standard assay for measuring glycolytic function in cells. First, injection of the sulfide solution produces a large artifact (oxygen decrease) followed by a variable period of inhibition of respiration. Fig. A plausible pathway of brood-pouch formation in the male seahorse. However, the Seahorse approach could reveal if a given cell type is able or not able to oxidize sulfide and would allow at least semiquantitative studies as the fastest rate observed is likely to approach the maximal rate of oxygen consumption possible in the presence of sulfide. Seahorses are unique in their mode of reproduction as the male, not the female, carries embryos in a brood pouch located on the ventral surface of the tail. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Since its introduction in 2006, Seahorse XF technology has been used in over 5000. The graph shows the oxygen concentration traces, in three individual wells. ECAR … Fig. Facts about seahorseThis video from sciencewithkids.com shows different facts about the seahorse.Seahorse are fish.A seahorse has 3 main fins. A possible alternative/evolution would be to use sulfide donors able to release and maintain low micromolar sulfide for extended period of time, while it is consumed by the cells. Also pay attention to whether the cells display an adverse reaction to the Seahorse assay medium. First, the sulfide injection caused a large dilution artifact with an immediate drop in the oxygen concentration reported by the detector. Within the pouch, the embryos are surrounded by a pseudoplacenta. OCR is reported in units of pmol/minute and ECAR in mpH/minute. The primordium of the brood pouch first appears as linear projections at both ventrolateral sides of the body. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Encyclopedia of Reproduction (Second Edition), Although viviparous female fish species supply nutrients to embryos during pregnancy, paternal nutrition transfer (patrotrophy) in, Formation of the brood pouch in the pot-bellied. XF Analyzers perform compound addition and mixing, label-free analytical detection, and automatic measurement of OCR and ECAR in real time. Seahorse XFp Extracellular Flux Analyzer The role of metabolism in cellular and physiological processes from cardiovascular function to immune response is well established, with many diseases now linked … (2) In the intermediate case, the eggs attached onto the male body are further protected by skin elongated from both ventrolateral sides. "Technology that can measure bioenergetic health is very new and Seahorse has the only platform that can contribute to our work," explained … Understand the connection between metabolic pathways and immune responses, and perturb immune activation and response in real-time through metabolic measurements. At specific time points of the culture, a labeling medium is prepared. Are you looking for help to solve an issue or need advice? Treat XF microplates for immobilization of nonadherent immune cells: Prepare a working solution of Cell-Tak in sterile H2O.5, Coat the XF96 cell culture plate with 10 μL of working solution of Cell-Tak.6. Incubate the cells at 37 °C, without CO2, for 30–60 min to allow medium temperature and pH to reach equilibrium before the first rate measurement. The treatment of data would need to consider the evolution of oxygen concentration in individual wells (Fig. The Seahorse XF24 instrument was recently developed as a multi-well plate-based assay platform that uses fluorescent optode detectors to measure oxygen consumption rates (OCR) and extracellular acid … Some cells do not tolerate the absence of serum or other supplements very well, in which case it is necessary to experiment with adding these back at the lowest possible concentration to avoid interference with the assay. Practically, the T cells are activated and cultured as described before. Complete solubilization is ensured by thorough pipetting, 30-s vortexing and a 5 min incubation at 100 °C. The XF tissue culture plates are provided in 8-well, 24-well and 96-well formats. Syngnathids are mainly divided into two groups, Urophori and Gastrophori. Modified from Wilson, A.B., Ahnesjö, I., Vincent, A.C., Meyer, A., 2003. I am performing a mito stress test on primary mouse hepatocytes using the Seahorse XF e 96, seeding 4000 viable cells in each well. These are unusual protocol and representation of results with the Seahorse. Second, when cellular respiration resumes after sulfide injection (top graph) this occurs at different time in the different wells. For Research Use Only. A Seahorse analysis is a fast and user-friendly way to identify global changes in glycolytic versus oxidative metabolism, and the use of several inhibitors during the assay can give an indication which substrates contribute to the observed metabolic phenotype. Evolution 57, 1374–1386. There are around 36 seahorse species, which are found in tropical and … I attached the cells to the plate with CellTak and they seem to be not detached along the run. Also pay attention to whether the cells display an adverse reaction to the Seahorse assay medium. Its unique highly ordered lamination, trisynaptic circuitry, and site for neurogenesis has contributed a wealth of information toward our current understanding of experience-dependent neuroplasticity at the systems, cellular, and molecular levels. After another 2-min centrifugation, cells are solubilized in gel-loading buffer (10% (w/v) SDS, 250 mM Tris–HCl (pH 6.8), 5 mM EDTA, 50% (v/v) glycerol, 5% (v/v) β-mercaptoethanol, 0.05% (w/v) bromophenol blue) at 5.6 × 103 cells/μL. BMP7 (Pepro Tech Inc.); store at − 20 °C. After gentle mixing, OCR and ECAR measurements are made multiple times. The projections elongated toward the ventral midline, and eventually fused together.
