We found that SOX7 (p < 0.01) and SOX10 (p < 0.01) genes showed a significant down-regulation in tumor tissues and SOX9 (p < 0.01) gene showed a significant up-regulation in tumor tissues when compared to corresponding adjacent benign prostate tissues, although the fold change in the expression level was not exactly same between the microarray analysis and QRT-PCR (Figure 1). The gene discussed is SOX10; the disease is neoplasm.
