Laboratory Introduction

Diseases such as autism, juvenile diabetes, asthma in children have increased in recent years. It has been thought that maternal environment during pregnancy is very important for the pathogenesis of those diseases. However, for fetus is in the complex context of development, it is very difficult to clarify the relation between the pathogenesis and fetal conditions.
In addition, it is known that the same protein works greatly variously in developmental stages. In our laboratory, we investigate the gene expressions, gene regulatory networks and physiological responses under several conditions such as hypoxia, infection, undernutrition. We studied the relation between fetal development and its responses to such environmental changes in uterus. Our aims are to find the useful clinical applications to save babies and next generation in uterus.
