Gene Affected HRAS: v-Ha-ras Harvey rat sarcoma viral oncogene homolog [ Homo sapiens ]
Origin This transgenic strain was generated by pronuclear injection of the transgene.
Strain characteristics This strain is carrying three copies of the human c-Ha-ras proto-oncogene, including its own promoter region. The rats are extremely sensitive to the induction of mammary carcinomas induced by chemical carcinogen such as DMBA and MNU.
Breeding Conditions Maintained as hemizygous males.
