COMPOSITIONS AND METHODS FOR THE TREATMENT AND PREVENTION OF METASTATIC DISORDERS

摘要

The invention relates to methods for the isolation of metastatic sequences and the isolated sequences. Cells from a cell line or an animal tissue are treated to form a cell line predisposed to cancer. Treated cells are implanted in an animal and incubated for a period of time sufficient for the cells to proliferate and develop malignant transplants. RNA from the malignant transplant and the primary tumor are analyzed by differential display polymerase chain reaction. Differentially expressed genes are cloned, reanalyzed, and sequenced. These genes and sequences can be used as probes in the diagnosis of neoplastic disorders, as probes to isolate metastatic sequences and as a therapeutic agent in the treatment of neoplastic disorders. The metastatic sequence may be a dominant metastatic sequence or a recessive metastatic sequence.
