| Outline of Final Research Achievements |
Aging is known as an irreversible decline of various tissue functions. We have identified a gene, target of NESH-SH3 (TARSH/Abi3bp) that was robustly upregulated at the beginning of cellular senescence in mouse embryonic fibroblasts. In addition, TARSH gene was dominantly expressed in lung tissue but the expression was strongly suppressed in human lung cancer specimens. These results suggest TARSH gene expression is involved in regulation of cellular proliferation and tumorigenesis. We predicted the candidate promoter of TARSH gene that includes the upstream of transcriptional initiation site and first intron, and validated the promoter function of that region. We are now going to narrow the functional region of the TARSH promoter. Consequently elucidation of senescence-associated regulation of TARSH gene expression may contribute to understanding the potential common mechanism underlying senescence, physiological aging and geriatric diseases including cancer.
