According to current research, the main biological processes and signaling pathways associated with m7G methylation in cancer are RNA metabolism, embryonic stem cell self-renewal and differentiation (13), tumor immunity (35), vascular development (36), FGF/TGF-β/Wnt pathway (37), WNT/β-catenin pathway (38), MAPK/ERK pathway (39), and so on. Here, TGFB1 is linked to cancer.
