In this study, we investigated the effect and mechanism of carnosine on the cell viability and proliferation of the cultured human gastric cancer SGC-7901 cells. In a previous study, we demonstrated that the interaction of Rubicon with p22phox increases cellular ROS levels. The standard molar enthalpy of formation and molar enthalpy of dissolution of SP at infinite dilution have been obtained. The following day, medium was replaced by DMEM (Sigma, D5030) containing 17.5 mM glucose (Sigma-Aldrich), 1 mM sodium pyruvate (Lonza), and 2 mM L-Glutamine (Life technologies). with sodium pyruvate (1 mM), L-glutamine (2 mM), and glucose (10 mM) 45 - 60 minutes before performing the XF a ssay. For glycolytic rate assays, cells were incubated in the absence of CO 2 for 1 h in non-buffered XF assay medium (Seahorse Bioscience) supplemented with 25 mM glucose, 2 mM glutamine and 1 mM sodium pyruvate. To do this, we cultured cells in a medium supplemented with high sodium pyruvate concentrations for 3 days before assessing mitochondrial function with the Seahorse assay. The glycolytic stress test was performed with 2 mM glutamine in . Glucose in cells is converted to pyruvate, and then converted to lactate in the cytoplasm, or to CO 2 and water in the mitochondria. glycolytic rates, Seahorse XF Glycolytic Rate Assay utilizes both ECAR and OCR measurements to determine the glycolytic proton efflux rate (glycoPER) of the cells (defined below). Five × 10 4 cells were FACS-sorted, centrifuged and seeded in XF96 plates 3-4 h prior to the assay in standard ES cell medium as described above. The run/cysteine-rich-domain-containing Beclin1-interacting autophagy protein (Rubicon) is essential for the regulation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase by interacting with p22phox to trigger the production of reactive oxygen species (ROS) in immune cells.

I have never worked with Seahorse, but in principle, if you put just pyruvate, as the oxaloacetate concentration inside mitochondria is too low, you will not be able to drive Krebs Cycle properly. One of the disadvantages of the Seahorse is that the relatively high surface and small volume of the medium allows fast interaction with ozone in the air, which destroys pyruvate. Once all ONs were collected for the run, they were removed from DMEM then chopped into 500 μm thick pieces using a McIllwain tissue chopper. Pyruvate + malate + ADP (PMA), oligomycin (oligo), FCCP, and antimycin A + rotenone (AA + ROT) B. MRR dependent by pyruvate + malate in fresh and frozen liver homogenates.
