[Apoptosis and carcinogenesis in aging: oxygen-peroxide aspect].
New facts are given by the author for the general oxygen-peroxide concept of aging, cancerogenesis and apoptosis. The idea is confirmed that the cell breath dysfunction leads to the oxidative stress firstly in mitochondria, then in cytoplasm and in the cell in general is the starting moment for the induction of the named processes. The superfluous formation of the active oxygen forms, peroxides of lipids and proteins as signal molecules creates disbalance between pro- and antioxidants, which size increases in aging cells and even more in tumor's and apoptosis cells. In the limits of these specialized "disbalanses" the named signal molecules play key role not only on starting "mitochondrial" stages of aging process, carcinogenesis and apoptosis, but also on following "performing" stages. They influence on the work of performing links (telomerase, oncoproteins, transcription factors, proteinkinase, endonuclease, caspase and so on).
