title: Rapid induction of malignant tumor in Sprague-Dawley rats by injection of RK3E-ras cells.
abstract: Several tumor animal models have been provided as a tool for developing cancer therapy. Here, we developed rapid, easy-to use, and cost-effective new rat animal model for invasion and metastasis of cancer using genetically k-ras-induced rat kidney cells (RK3E-ras). We observed tumor as early as 3 days after injection of RK3E-ras cells in subcutaneous of Sprague-Dawley rats. Tumor size and volume were increased exponentially for 2 weeks. The tail vein injected rats obtained the lethal infiltration in the lung within 2 weeks. This tumor animal model has great potential for studying cancer processes and short-term screening of variable cancer therapy strategy.
