About our reserch grup

Tadayuki Tsujita (T2)-group, in the Biochemistry laboratory is tring to understanding molecular mechanisms of the environmental stress sensor and transcriptional factor NRF1, NRF2 and others. To understanding physiological function of thouse mechamisms, we are utilising culture cell and genetical modified fish and mouse. Recentry, we are establishing new, sensitive screening system to find out chemical or natural compound to modulate those stress recognition system. This approach might be useful for develop the functional foods and medicine seeds.

We are enjoed to conduct dayly scientific activity and discussion. If you interested in our reserch group pleaase come and see us anytime!
