Abstract：
:Aging is a complex physiological process by which the functions of many organ systems deteriorate. Growing evidence shows that age-related changes and damage are causally related to oxidative stress and inflammatory responses from reactive species. The aim of this study was to identify differentially expressed genes in old and young kidneys of Fisher 344 male rats during the aging process using complementary DNA representational difference analysis (cDNA RDA). cDNA RDA is a subtractive technique for identifying a focused set of differentially expressed genes. The distinctive advantage of this technique is its capability of detecting differences in gene expressions at less than one copy per cell and identifying genes not previously described in the database. Reverse transcription-polymerase chain reaction with specific primers was applied to confirm the differences found by RDA. Twenty-one putative differentially expressed genes were identified. Sixteen genes were up-regulated during aging and were associated with stress-response and inflammatory reactions, while five genes were down-regulated. These data suggested that the inflammatory process is a plausible cause of the aging process.
