Proteomic analysis of clear cell renal cell carcinoma. Identification of potential tumor markers.

Objective: To identify new tumor specific proteins of renal cell carcinoma (RCC) using proteomic analysis.

Methods: Nine renal cell carcinomas were resected and these surgical operations were carried out from June 2007 to September 2008 in the Urology Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China. The cancer tissues and para-cancer normal tissues were preserved in liquid nitrogen.
