New discoveries in the last decade significantly altered our view on
mitochondria. They are no longer viewed as energy-making slaves but rather
individual cells-within-the-cell. In particular, it has been suggested that many
important cellular mechanisms involving specific enzymes and ion channels, such
as nitric oxide synthase (NOS), ATP-dependent K+ (KATP) channels, and
poly-(APD-ribose) polymerase (PARP), have a distinct, mitochondrial variant.
Unfortunately, exploring these parallel systems in mitochondria have technical
limitations and inappropriate methods often led to inconsistent results. For
example, the intriguing possibility that mitochondria are significant sources of
nitric oxide (NO) via a unique mitochondrial NOS variant has attracted intense
interest among research groups because of the potential for NO to affect
functioning of the electron transport chain. Nonetheless, conclusive evidence
concerning the existence of mitochondrial NO synthesis is yet to be presented.
This review summarizes the experimental evidence gathered over the last decade in
this field and highlights new areas of research that reveal surprising dimensions
of NO production and metabolism by mitochondria.
