GO, KEGG, and Reactome enrichment analysis revealed that PCAT19‐target genes were enriched in biological processes essential for cancer development such as epithelial development, lymph vessel morphogenesis, regulation of vascular process and carcinogenesis pathways, including VEGF signaling pathway, PI3K‐AKT signaling pathway, and cGMP‐PKG signaling pathway19, 20 (Figure 2A–C). The gene discussed is VEGFA; the disease is cancer.
