Prostate cancer is one of the most common malignant tumors in solid organs of old men. However, the patients are nearly 100 percent survivable if detected early. Prostate-specific antigen (PSA) is a valuable prostate cancer biomarker that is now wildly used for population screening, diagnosis, and monitoring of patients with prostate cancer. But PSA is not good enough for a biomarker because it can not distinguish benign prostate hyperplasia (BPH) from prostate tumor . Recently, there are some tumor marker still in study, for example: free prostate specific antigen¡]fPSA), complexed prostate specific antigen (C-PSA), kallikrein,prostate specific membrane antigen (PSMA). From previously study,we had found many different protein expressions between serum of normal and prostate patients. Mayven is one of the novel proteins that had been identified. The mRNA expression of Mayven in prostate cancer tissue is determined by quantitative RT-PCR. The result shows that the mRNA expression of Mayven in Benign Prostatic Hyperplasia (BPH) is about 5.0-11.3 fold than normal tissue , 12.7 fold in Prostate Cancer (PCa) stage T1 and 0.1- 3.7 fold after cancer stage T2. The Mayven gene expression is predominate in tumor stage T1, decrease after T2 stage. However the expressed pattern of mayven in BPH remains further investigation due to the limited sample size. Furthermore, with 2 dimensional electrophoresis (2¡VDE), we have found 7 differentially expressed proteins between tissue of normal and prostate patients, and these proteins are identified by MALDI-TOF mass spectrometry and MS-Fit. These identified proteins are Keratin 8¡]KRT8¡^, MAPKkinase5¡]MAP2K5¡^, Acid phosphatase (ACPP), Annexin A3¡]ANXA3¡^, Phosphoglycerate mutase 1 (PGAM1), Spindlin-like protein 2 (SPIN2) and Transgelin 2¡]TAGLN2¡^.
