Subsequently, we performed Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis using the differentially expressed genes (DEGs), and we noticed that the term “p53 signaling pathway” was significantly enriched in both COV434 and KGN cells (Figure 2B), indicating that 77–39 might regulate p53 pathway in GCT. This evidence concerns the gene TP53 and granular cell tumor.
