Breast Cancer Cell-Derived Exosomal miR-92b-3p Promotes Tumor Angiogenesis and Metastasis by Suppressing PTEN in Vascular Endothelial Cells
{{output}}
Background: Tumor-driven vascular remodeling is crucial for breast cancer metastasis; yet, the role of tumor-derived exosomal miRNAs in this process remains underexplored. This study aimed to investigate the clinical relevance and the underlying mechanism of b... ...
