We hypothesized that the HER2V777L mutation plays a vital role in metastatic breast cancer. To test this, H, P and HP mice were examined for metastasis to the lung or liver. Metastasis were not seen in HP mice likely bec
[Paragraph-level] PMCID: PMC10527017 Section: RESULTS PassageIndex: 9
Evidence Type(s): Oncogenic, Functional
Justification: Oncogenic: The passage discusses the HER2V777L mutation's role in metastatic breast cancer, indicating that it contributes to tumor development and progression, particularly in the context of lung metastasis observed in transgenic mice. Functional: The passage implies that the HER2V777L mutation alters the behavior of breast tumor cells, as evidenced by the invasive phenotype observed in vitro and the specific uptake of the NIR-trastuzumab imaging agent in tumor sites.
