    HER3 V104 mutations regulate cell signaling, growth, and drug sensitivity in cancer. (PubMed, Mol Carcinog)
    COS7 cells transiently transfected with the HER3-V104L mutation in the presence of HER binding partners showed higher expression of p-HER3, p-ERK1/2 versus HER3-WT in a NRG-independent manner without any change in AKT signaling. Overall, this study shows the clinical relevance of the HER3 V104L and the V104M mutations and its response to HER2, PI3K and ERK inhibitors.

    Characterization of diverse targetable alterations in ERBB2 and ERBB3 in 93,465 non-small cell lung cancers (NSCLC). (ASCO 2023)
    Background: Recently, fam-trastuzumab deruxtecan-nxki was approved for NSCLC with selected activating ERBB2 (HER2) mutations. Patritumab deruxtecan, a novel HER3 directed antibody drug conjugate, exhibits in vitro activity against HER3 mutations... Diverse ERBB2 and ERBB3 alt in NSCLC may predict sensitivity to anti-HER2/3 therapies, but not all classes of alts are detected/reported by all profiling assays. Utilization of comprehensive testing to guide biomarker definitions, treatment selection, and clinical trial enrollment is imperative.
