Both lucigenin and luminol have widely been used as chemilumigenic probes for detecting reactive oxygen species (ROS) production by various cellular systems. Our laboratory has previously demonstrated that lucigenin localizes to the mitochondria of rat alveolar macrophages and that lucigenin-derived chemiluminescence (CL) appears to reflects superoxide O2(-.) production by mitochondria in the unstimulated macrophages. In this study, we further examined the ability of lucigenin- and luminol-derived CL to assess O2(-.) and H2O2 formation, respectively, by isolated intact mitochondria. Mitochondria were isolated from monocytes/macrophages differentiated from monoblastic ML-1 cells. Incubation of the substrate-supported mitochondria with lucigenin at non-redox cycling concentration produced lucigenin-derived CL. Luminol-derived CL was also elicited with substrate-supplemented mitochondria in the presence of horseradish peroxidase (HRP). The lucigenin-derived CL was diminished extensively by the membrane permeable superoxide dismutase (SOD) mimetics, 2,2,6, 6-tetramethylpiperidine-N-oxyl and Mn(III) tetrakis(1-methyl-4-pyridyl)porphyrin, but not by Cu,Zn-SOD. On the other hand, luminol-derived CL was not observed in the absence of HRP and was significantly inhibited by catalase. A spectrum of agents known to specifically affect mitochondrial respiration exhibited corresponding effects on both lucigenin- and luminol-derived CL. Taken together, our results demonstrate that with isolated mitochondria lucigenin-derived CL monitors intramitochondrial O2(-.) production by the mitochondrial electron transport chain, whereas the luminol-derived CL detects H2O2 released from the mitochondria. As such, use of both probes provides a comprehensive and clear assessment of ROS production by mitochondria.

D008928 Mitochondria Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes.
