BPA can exert stimulatory action in cancer cells via the G-protein-coupled estrogen receptor 1 (GPER1, formerly known as GPR30, or G-protein coupled receptor 30) to activate the epidermal growth factor receptor (EGFR)/extracellular signal-regulated kinase (ERK)1/2 signaling pathway [8]. The gene discussed is EGFR; the disease is cancer.
