  • Publication number: 20090280512
    Abstract: The present invention provides a tumor marker more highly specific to renal cancer. The present invention provides a method for identifying the morbidity of renal cancer. A tumor marker for renal cancer comprising proteins identified from renal cancerous tissue. A method for identifying the morbidity of renal cancer by using the tumor marker for renal cancer. The method comprises measuring the level of the protein in a sample derived from a person of interest who is to be examined to identify the morbidity of renal cancer; and comparing an obtained measured level to a normal level of the protein, wherein an upregulation or a downregulation of the obtained measured level compared to the normal level is used as one of indexes indicating that there is a high possibility that the person of interest has renal cancer.
