Ultrasound-Controlled CRISPR/Cas9 System Augments Sonodynamic Therapy of Hepatocellular Carcinoma

to alleviate the adverse effects and augment the therapeutic efficiency of SDT. The hematoporphyrin monomethyl ether (HMME) in this system yielded abundant ROS to damage cancer cells under ultrasound irradiation, and meanwhile the generated ROS could induce lysosomal rupture to release Cas9/single guide RNA ribonucleoprotein (RNP) and destroy the oxidative stress-defensing system, significantly promoting tumor cell apoptosis. This study provides a new paradigm for HCC management and lays the foundation for the widespread application of CRISPR/Cas9 with promising clinical translation, meanwhile developing a synergistic therapeutic modality in the combination of SDT with gene editing.
