POU6F2 and neoplasm: POU6F2 was also highly expressed in normal tissue compared with tumor tissue (Figure 6D) and patients with high expressions of POU6F2 had a significantly worse overall survival (OS) rate (p = 0.0032) compared to patients with low expressions of POU6F2 (Figure 6E), but this was not statistically significant in DFS (Figure 6F).
