Research Abstract

To elucidate the process of DNA-Protein Crosslink (DPC) repair, we employed reverse genetic approach using chicken DT40 cells. It has been suggested that endogenous reactive oxygen species (ROS) is involved in formation of DPC. We generated several ROS scavenge enzyme genes knock out cells to elucidate mechanism of antioxidant defense system. In addition, we try to look for the therapeutic potential of DPC producing chemical, HMTA, in mouse level. All the results so far, already published in peer reviewed journals.
