Abstract
A transgenic mouse whose genome comprises the H/K-ras 4B chimeric gene to form a mammary tumor and, particularly, the expression vector producing H/K-Ras 4B chimeric protein by using MMTV (mouse mammary tumor virus) promoter. This protein contains the first 164 amino acids of the H-Ras followed by the last 24 amino acids of K-Ras 4B. The second, it relates to the transgenic mouse expressing the H/K-Ras 4B protein with a mammary tumor, and the third, the method of preparation.
