1 We further explored the molecular mechanisms that enables these cells to be primarily resistant to T-DM1 and found that EGFR was activated in the spheroids, leading to an increased HER2 tyrosine phosphorylation. Tyrosine epidermal growth factor receptor Homo sapiens
2 Blocking EGFR activity by erlotinib reduces HER2 tyrosine phosphorylation and enhances HER2 cell surface expression. Tyrosine epidermal growth factor receptor Homo sapiens
