PAK4 and neoplasm: The data showed that high expression of PAK4 or G6PD was significantly associated with poor pTNM stage (P=0.02 or P=0.037, respectively) and histological grade (P=0.003 or P=0.042, respectively), (Tables 2 or 3), but not with tumor size (P=0.932 or P=0.649, respectively) and depth of invasion (pT), (P=0.656 or P=0.114, respectively).
