| Research Abstract |
Evaluation of porphyrin derivatives on lives were carried out in the points of effects on cell differentiation as well as on transcription. We, evidenced that Bach1 is the first heme-controlled transcriptional factor in vertebrates. Bach1 is shown to be regulated heme oxygenase-1, which is one of the members of defense system against chemical hazards. Thus, it seems to be possible the evaluation of toxicity via Bach1. In addition, Bach1 also regulates erythroid cell differentiation through globin ge nes. The function of Bach1 can be exchanged by metalloporphyrins other than heme, suggesting some porphyrin derivatives could be applied as drugs to control differentiation.
