Can cancer cells create their own blood vessels to spread to the brain? This research examines vascular mimicry (VM) as a facilitator of melanoma brain metastasis (MBM), investigating its significance in this aggressive cancer. The study found that VM density is elevated in MBM compared to extracranial specimens and is associated with tumor volume and CNS edema. It also indicates a role for YAP and TAZ, two transcriptional co-factors, in tumor cell-vasculogenesis and brain metastasis. Treatment with anti-YAP/TAZ therapy in mouse models effectively inhibits VM and prolongs survival. These data suggest that VM is an important and targetable mechanism in melanoma. Inhibiting VM might be useful for treating MBM, an area of high unmet clinical need, with important implications for future treatment regimens for these patients.
Published in Cellular and Molecular Life Sciences, this study is well-suited to the journal's focus on molecular mechanisms underlying biological processes. By exploring vascular mimicry in melanoma brain metastasis, the article aligns with the journal's emphasis on cellular and molecular pathways involved in cancer progression. The research fits within the scope of providing insights into potential therapeutic targets at the molecular level.
