Additionally, the targeting of G protein-coupled receptors, including CXCR4, CCR5, and A2aR, as well as growth factor receptors such as VEGFR and EGFR, and interleukin receptors, interferes with pathways that are critical for tumor promotion, resulting in diminished angiogenesis, metastasis, and immunosuppression. This evidence concerns the gene EGFR and neoplasm.
