EGFR and breast carcinoma: blocking ATP from binding to the tyrosine kinase (TK) domain of HER2 upon treatment with a potent, reversible, selective dual-HER1/HER2 TK inhibitor lapatinib prevents EVOO polyphenols-induced inhibition of breast cancer cell growth, thus suggesting that EVOO lignans and secoiridoids may function as phosphotyrosine-receptor kinase blockers by competing with ATP; and 4).
