ABSTRACT
Determination of oxygen consumption is one of the most valuable methodologies to evaluate mitochondrial (dys)function. Previous studies demonstrated that a widely used protocol, consisting of adding the ATP synthase inhibitor oligomycin before mitochondrial respiratory uncoupling by sequential addition of a protonophore (e.g., carbonyl cyanide 3-chlorophenyl hydrazone [CCCP]), may lead to underestimation of maximal oxygen consumption rate (OCRmax) and spare respiratory capacity (SRC) parameters in highly glycolytic tumor cell lines. In this dataset, we report the effects of the glycolytic inhibitors 2-deoxy-D-glucose, iodoacetic acid, and lonidamine on overcoming the underestimation of OCRmax and SRC in oligomycin-treated cells. We propose a protocol in which 2-deoxy-D-glucose is added after oligomycin and just before the sequential addition of CCCP to avoid underestimation of OCRmax and SRC parameters in A549, C2C12, and T98G cells. The oxygen consumption rates were determined in intact suspended cell lines using a high-resolution oxygraph device. The data can be used in several fields of research that require characterization of mitochondrial respiratory parameters in intact cells.
