The invention provides isolated nucleic acid and amino acid sequences of novel human tumor suppressors, antibodies to such tumor suppressors, methods of detecting such nucleic acids and proteins, methods of screening for modulators of tumor suppressors, and methods of diagnosing and treating tumors with such nucleic acids and proteins. A subject is selected for treatment to stimulate the immune response to a conventional vaccine. The magnet is magnetized so that magnetic poles are oriented in an axial direction.
