WebMetastases from brain cancer are driven by an overexpression of the human epidermal growth factor 2 (HER2) gene. Previous research has attributed targeted drugs ineffectiveness to their inability to penetrate the blood-brain barrier, but further research is needed to support this belief. WebOct 21, 2024 · Overexpression of HER3 is often associated with overexpression of HER2 and/or EGFR, playing an important role as co-receptor in HER2 + breast cancer and in a subset of EGFR-positive lung tumors [45,46,47,48]. Furthermore, breast cancers often show co-expression and positive correlation between HER2 and HER3 [49, 50].
