title: [Iron-sulfur centers in the mitochondrial respiratory chain at different stages of cell culture growth of the hamster Cricetulus griceus].
abstract: The dramatic diminishing of the concentration of the N-2 iron-sulfur centre of NADH-dehydrogenase of mitochondria during the growth of cell culture of hamster fibroblasts with the subsequent recovery of concentration to the initial level was discovered by means of low-temperature ESR spectroscopy. It was concluded that the results obtained are due mainly to the decrease of the number of respiratory chains, but not to the change of the electron transport chain structure.
