Polypeptide, nucleotide sequence thereof, and method for using the same for preventing dna synthesis and inhibiting cell proliferation

Abstract

A polypeptide represented by SEQ. ID.NO. 1. And a method for treatment of a tumor and another disease associated with abnormal cell proliferation, the method including administering a pharmaceutically-effective amount of the polypeptide to a patient in need thereof.

The invention claimed is: 
     
         1 . A polypeptide represented by SEQ. ID.NO. 1. 
     
     
         2 . A method for treatment of a tumor in a patient comprising administering to the patient a therapeutically-effective amount of the polypeptide of  claim 1 . 
     
     
         3 . An isolated polynucleotide comprising a nucleotide sequence encoding the polypeptide of  claim 1 , the nucleotide sequence comprising a double stranded DNA comprising a first single strand represented by SEQ. ID. NO. 3 and a second single strand represented by SEQ. ID. NO. 4. 
     
     
         4 . A method for treatment of a tumor in a patient comprising administering to the patient a therapeutically-effective amount of the isolated polynucleotide of  claim 3 .
