Renal oncocytomas are benign tumors characterized by dense accumulation of mitochondria the cause of which remains unknown so far. Consistently, mitochondrial DNA content and the amounts and catalytic activities of several oxidative phosphorylation (OXPHOS) complexes were known to be increased in these tumors, but it was not ascertained that the OXPHOS system was functional. Here we investigated mitochondrial complex I and found that its NADH dehydrogenase activity and protein content were specifically decreased in oncocytomas, in stark contrast with the parallel decrease of all respiratory chain complexes in other, malignant, renal tumors.
