Areas of specialization Molecular Biology
Laboratory/research office Cell Proliferation Control Laboratory
Control of cell proliferation is the most fundamental and important aspect of life. When cells proliferate, chromosomal DNA, the blueprint of every organism, must be precisely replicated and segregated. Any defect in these processes can result in death or in diseases such as cancer. Our laboratory is conducting research using yeast, which is a model system of eukaryotic cells, to reveal the regulatory mechanism of cell cycles and chromosomal DNA replication, and further to understand the mechanism of stable genome maintenance.
Current reseach topics Regulation of chromosomal DNA replication in eukaryotes
Mechanisms for stable genome maintenance
Mechanisms for site-specific gene amplification
Interplay between the initiation of DNA replication and the regulation of chromatin
