Research Abstract

Chromosomal translocations often cause a variety of diseases, such as cancers or infertility. To find mechanism of a frequently occurring translocation in humans as an example, I used medaka germ cells as a model. In addition, I made a translocation model system of a human cell line and made an attempt to find factors involving the translocation. As a result, I proposed a novel mechanism of the recurrent translocation. This result might lead to a new gene transfer technique in the future.
