Furthermore, a correlation analysis of AOC4P expression with clinicopathological parameters revealed that the AOC4P expression level was predominantly decreased in late-stage tumor tissues (Figure 1C, Kruskal-Wallis test p = 0.0207) and negatively correlated with tumor size (Figure 1D, Wilcoxon rank-sum test p = 0.0551). This evidence concerns the gene AOC4P and neoplasm.
