  In the present study, we originally designed triple-combination array analysis to identify tumor related genes in Hepatocellular Carcinoma (HCC). Using this method, the six transmembrane epithelial antigen of prostate family 4 (STEAP4), it was reported association with obesity and insulin-resistance, was detected as a candidate tumor suppressor gene. We found 32 of 48 (66.7%) tumor tissues showed STEAP4 promoter hypermethylation, and its expression level was significantly reduced in tumor tissues (p<0.0001). Methylated cases demonstrated significantly poorer recurrence-free survival (p=0.0462) and overall survival (p=0.0411). Triple-combination array analysis represents a useful technique for identifying novel tumor-related genes in HCC. .. View More»
