Metastasis inducing DNA's

摘要

The invention relates to metastasis inducing DNA's, a method of identifying such DNA's and their use in diagnosis and therapy. It includes a method of screening and recovering Met-DNA comprising the steps of: (1) transferring fragments of human DNA from malignant, metastatic cancer cells into a cell line that produces only benign, non-metastasizing tumours when injected into a syngeneic animal; (2) injecting the transformed cells into a syngeneic animal; (3) selecting those animals in which metastasizing tumours have been identified; and (4) recovering the Met-DNA therefrom.
