Research Summary

Momoko  Horikoshi(M.D., Ph.D)

The prevalence of life-style related diseases, such as diabetes mellitus, is progressively increasing worldwide including Japan. Patients with diabetes may develop micro- and/or macro-vascular complications if they are not treated properly, and will face deterioration of prognosis and quality of life. The pathogenesis of the disease is multi-factorial, and genetic susceptibility is considered as an important factor for the development and progression of diabetes. By using genome-wide genetic data, our laboratory aims to identify genetic regions associated with diabetes to better understand the mechanism through which the disease develops, and translate the information into clinical practice.
