DNA damage and epigenetic mechanisms of agingifferentiate, and also cells which retain their stem cell function. Whereas classical genetic inheritance is concerned with individual cell lineages, epigenetic changes during development commonly occur in groups of cells sometimes called “polyclones” (Crick and Lawrence, 1975). Such changes may be

Antioxidant genes and other mechanisms involved in the extended longevity of ,ions leads to a normal life span. There exists a critical period in larval life during which the L-HD animal programs the expression of genes in the young adult. This takes the form of a coordinated increase in specific antioxidant mRNA levels and enzyme activities in the 5 day old L-HD adult, a tim

Age-associated changes of oxidative modification and turnover of proteinsxidatively modified proteins preferentially was identified with insulin-degrading enzyme. The enzyme activity, however, did not change with age. Further investigations are required to understand the molecular mechanisms of age-associated decline of protein turnover.

Free radicals and muscle damage due to immobilization of old animals: Effect of growth hormonethe immobilized muscles. Administration of growth hormone (GH) to the immobilized animals slowed down muscle atrophy, had a positive effect on reducing the enzyme activity changes, and decreased oxidative damage by reducing the levels of protein oxidation and lipid peroxidation in immobilized muscle

PCR analysis of mitochondrial DNA from normal and transgenic glutathione peroxidase miceealing stringency. The secondary bands tend to obscure the presence of structural abnormalities in mtDNA, such as deletions, particularly when they are present at very low concentrations. Use of total cellular DNA for PCR, as is usually done, aggravates this situation further in view of the relative
