Laboratory Introduction

The institute for Animal experimentation is a facility for rearing laboratory animals with about 30 care takers. We are now maintaining about 30,000 laboratory animals including mice, rats, rabbits, dogs, pigs and monkeys. In our research laboratory, we are investigating comparative and experimental medicine and educating graduate students in the field of laboratory animal science and medicine. We perform research using laboratory animals to try to find out human characteristics. We are studying the causes and pathology of hereditary diseases using spontaneous and transgenic animal models for human diseases such as rats with diabetes mellitus, mice with congenital cataracts, mice with Menkes disease and rats with Wilson's disease. In addition, one of the recent topics in our laboratory is pathophysiological role of glycosphingolipids (GSLs). We found that aberrant expression of a GSLs synthase dramatically promotes proliferation of intestinal epithelial cells. It is likely to be a model of initial stage of colon cancer. Other models reveal various changes in their phenotypes, including metabolic disorder, dysontogenesis and cancer. We are exploring molecular events underlying these phenotypic change.
