Research theme
The mechanisms of drug resistance in cancer.
Thanks to the development of molecular targeted drugs, treatment for cancer progressed dramatically. However, a part of the patients invariably develop resistance to drugs after long time drug treatment. We are trying to elucidate “How cancer cells develop resistance mechanisms to drugs”. Especially, our interest is the mechanism and the role of drug tolerant cells which emerge at the beginning of drug treatment.
The effect of chemical substances on cancer malignancy.
We always have opportunity for exposure to chemical substances such as pesticide, environmental pollution, microplastics, and nanoparticle. The risk of those chemical substances are evaluated mainly as a carcinogen which cause cancer initiation. We are trying to elucidate the effect of chemical substances on cancer malignancy which is a final step in cancer progression such as metastasis, immune evasion, and drug resistance.
