Research Activities
1) Screening of the tumor suppressor genes by a microcell-mediated chromosome transfer system:Introduction of normal human chromosomes 3 and 11
into A549 lung adenocarcinoma cell line have showed the suppression of
tumorigenicity, but not the introduction of chromosome 7 (1).
2) Gene mapping in humans and several laboratory animals: Over 80 genes
were mapped, and comparative mapping has revealed the conservation of
syntenic groups of genes along with extensive homologies of chromosome
banding patterns (4).
3) Molecular cytogenetics in the domestic cat: Establishment of the chromosome nomenclature of the domestic cat (2). Assignment of the cat
immunoglobulin and T-cell receptor genes and determination of the
integration sites of FeLV genomes in cat lymphoid tumor cell lines by
FISH and Southern blot analyses (5).
4) Cloning of genes responsible for reciprocal chromosome
translocation: Intronic U50 snoRNA host gene has been mapped at the
chromosome breakpoint t(3;6)(q27;q15) of human B-cell lymphoma.

The Society of Chromosome Research (Councilor)
Future Plan
Investigating the pathophysiological causation of diseases based on the specific chromosome abnormality found in each malignant lymphoma. Especially focusing on the gene amplification occurring in several tumors.

Messages to Students
I hope you find your own theme during your graduate school days. It'll be tough to resolve a given subject completely within a short period of time. What is important? Never quit when facing knotty missions, keep pushing forward, and improve your skills, I believe. Enjoy your research in the field of life science.
