Cancer Gene Therapy
Research from Tohoku University has provided new information about cancer gene therapy
April 29th, 2008
"A physical method using ultrasound (US) and nano/microbubbles (NBs) can deliver exogenous molecules noninvasively into a specific target site. In this study, we evaluated the application of this technology to cancer gene therapy using prodrug activation therapy," investigators in Sendai, Japan report. "Low-intensity pulsed ultrasound (1 MHz; 1.3 W/cm(2)) and NBs were used to transduce the herpes simplex thymidine kinase (HSVtk) gene in vitro, leading to gene transfer. The addition of ganciclovir (GCV) to the transduced cells led to HSVtk/GCV-dependent cell death mediated by apoptosis. This technology was then assessed in vivo, using mice bearing subcutaneous tumors (1...
