Abstract
1. A better understanding of the molecular effect on aging in the brain may help reveal important aspects of organism aging, as well as the processes that lead to aging-related brain dysfunction. In this study, the aging-specific expression genes of the murine cerebrum were investigated by using the technique of DDRT-PCR in two senescence-accelerated mouse strains, SAMP10/Ta and SAMR1TA. 2. Through comparing gene expression profile among the age, 2, 4, 12, and 18 month of the SAMP10/Ta strain, four differential fragments have been found, and comparing gene expression profile between the two mouse strains, 24 fragments have been detected, 7 and 17 of them belong to SAMP10/Ta and SAMR1TA, respectively. 3. Sequencing analysis indicated that most of those fragments are homologous with some of certain gene cDNA that are related with senile. The data obtained from this study suggest that many genes are involved in the senile process and accelerate senescence phenotypic pathologies in SAMP10/Ta.Entities:
