Abstract：
:We applied a differential display method to screen mRNAs isolated from a newly established cell line that carried a wild-type p53 transgene under control of the lactose operon. To investigate the p53 signaling pathway, we looked for genes whose expression was significantly induced or suppressed by induction of wild-type p53 protein, and identified seven. DNA sequence analyses revealed that the two genes that were upregulated encoded isozyme 6 of aldehyde dehydrogenase (ALDH6) and subunit I of cytochrome c oxidase (COI). The five genes that were downregulated encoded protein-tyrosine kinase (Syk), high mobility group chromosomal protein 17 (HMG-17), transferrin receptor, human alpha-tubulin, and sds22-like protein. The results indicated that genes related to cell cycle regulation, cell respiration, and cytoskeletal structure are involved in the process of growth arrest induced by wild-type p53.
