    Her2 interaction domain mutations in breast cancer patients are responsible for receptor switch and therapy failure against Her2 targeted medicines (EACR 2022)
    Receptor switching to other HER family members in Lapatinib resistance and HER2 receptor tyrosine kinase domain mutations have been elaborated in promoting resistance. BC cells over-expressing HER2-WT or S305C were found sensitive to Trastuzumab (P>0.001) or Neratinib (P>0.001), whereas cells with G309A, S310Y or P523S mutation were non-responder to those drugs as revealed by short-term, long-term viability, anchorage-independent growth and Immunoblot assessments. Conclusion The structural changes ensued after HER2 interaction domain mutations alters the downstream signalling cascades and impacts the therapy response to HER2 targeted medicines.
