| Outline of Final Research Achievements |
We analyzed molecular mechanisms of maintenance system for nuclear redox balance to support the epigenome regulation. Using gene-deleted cells and gene-knockout mice, we successfully showed that NRF2 and FDH cooperatively function through the regulation of GSH in the protection from oxidative damage in liver. We also found that formaldehyde increased in the Nrf2::Fdh double mutant cells, compared to respective single mutant cells. To examine the importance of NRF2-FDH-GSH system in cancer cells, we successfully established a model cancer cell line, which rigorously form tumors in allograft experiments in NRF2-dependent manner.
