Experimental procedures: Several ovarian cancer cells lines (OVKATE, OVSAHO, NIHOVCAR3) as well as a patient derived primary cell line (GD13-13P) were utilized for all experiments. The Seahorse Flux Analyzer in conjunction with several metabolic inhibitors including etomoxir (a carnitine palmitoyltransferase 1 inhibitor), 2-deoxy glucose, FCCP and rotenone were utilized in these experiments to evaluate the oxygen consumption rate(ORC) and extracellular acidification rate(ECAR) of cells at their basal and post metabolic inhibitor state. OCR and ECAR were used as markers for mitochondrial respiration and lactate production, respectively. NIHOVCAR3 cells were co-cultured with differentiated 3T3L1 adipocytes and then subjected to BODIPY fluorophore (493/503) fatty acid staining and confocal microscopy to investigate the potential relationship between ovarian cancer cells, adipocytes and metabolism.
