CAV1-DOT1L axis in TAM-derived EVs orchestrates VM and sensitises PDAC to combined VM and VEGF targeting

Listen to this summary

The authors investigate the regulatory mechanisms of vasculogenic mimicry (VM) in pancreatic ductal adenocarcinoma (PDAC) and explore therapeutic strategies to counteract VM-driven tumor progression. They identify a CAV1-DOT1L-ATG5 axis in tumor-associated macrophage (TAM)-derived extracellular vesicles that promotes VM, and demonstrate that combined inhibition of DOT1L and VEGF receptor (VEGFR) effectively targets both VM and compensatory angiogenesis, offering a promising approach for PDAC treatment.
