Yusuke Nakamura, MD, PhD
Scientific Advisor, Cell Therapy Program
Dr. Nakamura is a prominent geneticist and cancer researcher in Japan and best known for developing the Genome-Wide Association Study (GWAS). He is one of the world’s pioneers in applying genetic variations (Variable Number Tandem Repeat (VNTR) and Single Nucleotide Polymorphism (SNP) markers) and whole genome sequencing, leading the research field of personalized medicine. Dr. Nakamura successfully identified VNTR markers in 1987 and tumor suppressor gene APC in 1991. Furthermore, several genetic polymorphic markers developed and mapped by his research groups at the Japanese Foundation for Cancer Research and the University of Tokyo, have contributed to map and clone genes responsible for hereditary diseases, as well as those related to drug response and involvement in cancer. In 2001, Nakamura and his colleagues of RIKEN SNP Research Center developed the methodology of Genome-Wide Association Study (GWAS), and using this method his research group first discovered functional SNP in the lymphotoxin-α gene that are associated with susceptibility to myocardial infarction in 2002, which was a breakthrough in the research field of medical genetics. Furthermore, the RIKEN SNP Research Center led by him made the largest contribution in the Phase 1 HapMap project of the International HapMap Consortium published in the scientific journal Nature in 2005. Nakamura has also focused on applying genetic information to improve the care of cancer patients, working to bring his laboratory’s discoveries into clinical practice. In 2001, his cancer research at the University of Tokyo led to the formation of OncoTherapy Science, a successful public Japanese biotechnology company that concentrates on new cancer therapies. Currently, Dr. Nakamura is advising Celloram's cell therapy development program team.
