LEA rats were provided fron Kyoto Bioresource Center in 2006. Then LEA rat ES cells having Oct4-Venus gene and Oct4-Venus Tg rat strain (LEA-Tg(Pou5f1-YFP*)3Ncco) were established. ES cells were establised from Oct4-Venus Tg rat, p53 heterozygous-ES cells were made by gene targeting method and finally p53-heterozygous rat strain (LEA-Tp53tm1(AmCyan1)Ncco) was established by germline transmission. Deposited p53-heterozygous rats do not have Oct4-Venus. Vector: AmCyan1 (Clontech)
AmCyan1 expression under CAG-promoter and deletion of p53 gene expression. Almost all p53 heterozygous rats die of tumor within one year of age.
