    Cannabinoid CB2 receptor drives trastuzumab resistance and predicts durable anti-HER2 response. (PubMed, Oncogene)
    We also propose dual HER2/EGFR targeting and non-CB2R-selective cannabinoid therapies as potential strategies to overcome CB2R-mediated trastuzumab resistance. Together, these findings position the endocannabinoid system as a pivotal and actionable node to elucidate, anticipate, and counteract resistance to HER2-targeted therapies.

    Discordance between IHC/FISH and RNA expression-based assessment of ER/HER2 status, and its prognostic impact assessed by propensity score matching. (PubMed, BMC Cancer)
    ER and HER2 RNA expression levels should be considered for confirmation in patients with PR-negative/HER2-positive status, as discordance between IHC and RNA-based assessment is significantly associated with worse recurrence-free survival outcomes.

    Differential response of HER2 - and HER2 + breast cancer cells to quinazoline and triazole derivatives: advancing receptor subtype-specific phytochemical targeting. (PubMed, Mol Divers)
    The HER2 - cells showed a greater reduction in ER expression with the quinazoline derivative (F0922-0471) than with the triazole derivative, which significantly reduced HER2 expression in HER2 + cells, underscoring their receptor-specific effects. This study concludes that Quinazoline (F0922-0471) and Triazole derivatives (F2865-0609) show potential as receptor-specific, multi-targeted anticancer agents for distinct breast cancer subtypes, warranting further preclinical and clinical evaluations.

    The VEGF/VEGFR axis in triple-negative breast cancer: a comprehensive review of therapeutic strategies. (PubMed, Gene)
    In addition, we highlight the importance of molecular stratification and biomarker-driven approaches to identify patients most likely to benefit from anti-angiogenic therapy. Overall, while VEGFR-targeted therapy alone has shown limited success, rational combination strategies and improved patient selection may significantly enhance its clinical utility in TNBC.
