Outline

The number of patients suffered from diseases such as cancer, infectious diseases, the circulatory diseases and dementia is expected to increase, associated with advancement of aging society in our country. It is necessary to prevent lifestyle-related diseases, to improve and maintain functions for performing social life, and then to realize the extension of healthy life expectancy. Therefore, it is important to elucidate the cause of such diseases.
In our laboratory, we will implement research and education programs necessary for preparing for aging society. We will focus on studying etiology, onset mechanism, prevention, and diagnosis of cancer and infectious diseases by using genome-omics analyses with the single-cell techniques.

The current research themes are as follows:

1. The microenvironment state of the carcinoma tissues is involved in diagnosis and clinical conditions. To observe such microenvironmental states, we will study the diversity of the cancer tissue using single cell gene expression and omics analyses.
2. HBV is a causative agent for cirrhosis, resulting in hepatocellular carcinoma. However, it is not clear how infection with HBV causes such liver diseases. We will study identification of molecules relating to promotion or inhibition of HBV replication, show molecular mechanisms of maintaining latent HBV in cells, and then try to develop antiviral drugs.
