| Research Abstract |
The purpose of this study is to construct the stable tumor bearing medaka line and to apply the line to drug screening. We intended to establish the melanoma model which can be detected tumors without autopsy for chemical screening in water tank. With cross transgenic(Tg)-tyr : HRAS^<G12V> medaka with Tg-hsp : cre medaka, we could obtain medaka line induced human HRAS^<G12V> by heat treatment. All of the double Tg medaka had melanophore hyperplasia or melanoma at six month post fertilization. Preliminary administration of sorafenib to this double Tg medaka having tumor showed significant inhibition of tumor growth and elongation of longevity.
