Low‐Power Ultrasound with Microbubbles Improve Oxygenation and Doxorubicin Uptake in Hypoxic Triple‐Negative Breast Cancer

USMB improves the TNBC microenvironment and enhances drug delivery by promoting perfusion and oxygenation, likely via NO signaling. These findings support USMB as a promising strategy for TNBC combination therapy and highlight NO as a potential therapeutic target.
