PAK6 expression in GC tissues. Representative IHC photographs reveal high PAK6 density in tumor tissue, low density in nontumor tissue (A), and density from TNM stage I–IV (B). (C) Scatter plots for IHC staining score in unpaired nontumor tissue (n = 242) and tumor tissue (n = 242) from the training cohort. (D) Percentage of patients with high intratumoral PAK6 expression increased moderately accompanied by disease progression from TNM stage I–IV (data from the trainging and validation cohort). Scale bar, 100 μm.
