A NEW METASTATIC HUMAN TUMOR ASSOCIATED MOLECULE, METHODS TO DETECT BOTH ACTIVATED GENE AND PROTEIN AND TO INTERFERE WITH GENE EXPRESSION

摘要

This disclosure characterizes the function and the expression of the human protein encoded by tm9sf4. The protein is highly expressed in malignant tumor cells and therefore is a novel marker for malignancy. Moreover, the protein is involved in the phagocytotic character of tumor cells. This disclosure provides methods and tools to diagnose and follow up malignancy of tumors. Furthermore, means to inhibit phagocytotic character of tumor cells as well as means to treat cancer are provided.
