Theme: p53 as a tumor suppressor gene and an important signaling molecule involved in various cellular functions

Dr. Arnold J. Levine discovered the p53 protein in viral transformed cells and tumors. The c-DNA and gene for the p53 protein were cloned and the gene was shown to be a tumor suppressor gene preventing cancers. Fifty-five percent of all human cancers have mutations in the p53 gene and another twenty to thirty percent of cancers inactivate p53 functions. The p53 protein integrates signals and responds to cellular stress such as DNA damage, poor oxygen tension or inadequate energy sources. The p53 response to stress results in either cell cycle arrest or programmed cell death. The research on p53 will help our understanding of various cellular functions and mechanisms for tumor development.

Reason for Selection

Theme: Elucidation of various genetic diseases through human genome analysis

Dr. Yusuke Nakamura and his coworkers contributed to chromosomal mapping of hereditary diseases and cancer-related genes through isolation and distribution of a large number of polymorphic DNA markers. They also made a number of important findings in the cancer research field; isolation of the APC gene (a tumor suppressor gene for colorectal cancer) as well as p53-target genes including p53R2 (a key enzyme for repairing damaged-DNA) and BAI1 (an angiogenesis inhibitor). In addition, his group discovered genes responsible for genetic diseases including gelatinous drop-like corneal dystrophy and tip-toe walking, a mouse model of ossification of the posterior longitudinal ligament of the spine. Identification of disease associated genes will lead to development of new diagnostic and therapeutic strategies for diseases.
