Gene therapy conventionally utilizes virus to correct diseased genes for eliminating cancer, but safety risks and off-target effects of viral method largely limit their clinical translation.
Therefore, CUHK team combined RNA interference technology and ultrasound microbubble system to form a novel virus-free gene therapy. The invention specifically delivers gene silencing particles into tumor without using any virus. It can serve as a rapid evaluating platform for therapeutic efficiency of new gene targets preclinically, as well as development to be a safe anticancer therapy clinically.
