| Outline of Final Research Achievements |
In this study, it was revealed that anti-viral factor encoding OAS1 gene is up-regulated by ELF-1, suggesting a new therapeutic method for leukemia introducing the transcription factor encoding gene(s) into cells. Moreover, it was shown that a natural compound resveratrol affects duplicated GGAA-motifs to activate promoter activities of the human TP53 and HELB genes, which encode tumor suppressor p53 and G1/S transition regulatory DNA helicase, respectively. The results suggest that natural product or introduction of specific genes into cells could be applied for cancer treatment up-regulating DNA-repair system at a transcriptional level. On the basis of these observations, we have started to investigate promoter regions of the human mitochondrial-function or DNA-repair associated genes analyzing their responses to various anti-tumor/anti-aging drugs.
