KEGG pathway analysis showed that the four pathways with the strongest positive correlations with PCBP1-AS1 expression were protein export, proteasome, p53 signaling pathway, and glycolysis gluconeogenesis; the four pathways with the strongest negative correlations were phosphatidylinositol signaling, basal cell carcinoma, bladder cancer, and Notch signaling, as shown in Figure 8A. This evidence concerns the gene PCBP1 and basal cell carcinoma.
