Furthermore, M2 TAMs secrete Epidermal Growth Factor (EGF) (Zeng et al., 2019; Wu et al., 2020b), which binds to EGFR on cancer cells, for activating their growth signaling including MAPK/ERK (Liang et al., 2022) and PI3K/Akt pathways (Zhang et al., 2021b), promoting cell motility and invasion (Haque et al., 2019; Zeng et al., 2019; Onal et al., 2021). The gene discussed is EGF; the disease is cancer.
