TGFB1 and neoplasm: KEGG analysis illustrated the enrichment of DEGs in several pathways associated with tumor genesis, progression, and prognosis, including cell adhesion molecules, TGF-β signaling pathway, focal adhesion, proteoglycans in cancer, ECM–receptor interaction, PI3K–Akt signaling pathway, human papillomavirus infection, and cytokine–cytokine receptor interaction (Figure 4(d)).
