The principal research focus in our department involves programs devoted to the molecular, nutritional, and genetic bases for leukemia/cancer and other common life-style related diseases. Four faculty members with many foreign postgraduate students pursue research linked to human diseases, including adult-T cell leukemia (ATL) with HTLV-1 infection, the patients of which are mainly accumulated in the southern part of Kyushu island including Miyazaki.
A broad spectrum of technical approaches utilizing the tools of enzymology, molecular biology, and genetics is being used to understand the origins of diseases which are common in our population. Among the studies underway are analyses of the inheritance and genetic analysis of cancer, mechanisms of resistance to anti cancer drugs by stress response (Nature comm 2014), which is related to leukemia stem cells with EVI1 (Cell 1988) or MEL1/PRDM16 transaction factors (Blood 2000), and altered metabolic function by AMPK linked to altered glucose metabolism (Cell stem cell 2015). Faculty members in this research area collaborate in a wide variety of studies with investigators in basic sciences and clinical faculties at both nationally and internationally. These investigations include basic research into the metabolism of drugs and environmental toxins, apoptosis, analyses of metabolism and gene regulation in normal and cancer cells, and direct diagnosis of cancer, diabetes, and other disorders in humans by molecular genetic and immunological techniques.
