Polyunsaturated fatty acids modify oxidative metabolism. A- Oxygen consumption rate (OCR) of rhabdomyosarcoma cells treated with either DMSO control (0.1% final concentration), combination omega 3 (Ω3) at 25 μM or 50 μM, or CLA at 25 μM or 50 μM for 24 hours. B- Baseline OCR following treatment described above. C- OCR following addition of oligomycin, an inhibitor of oxidative phosphorylation. D- Peak OCR following addition of carbonyl cyanide p-[trifluoromethoxy]-phenyl-hydrazone (FCCP), a mitochondrial uncoupling agent, in addition to previously added oligomycin. NOTES: * indicates p < 0.05, ** indicates p < 0.01, and *** indicates p < 0.001 compared with control. † indicates p < 0.01 (significantly less than control).
