Newswise — On October 4, JoVE, the Journal of Visualized Experiments, will publish a new technique for breast cancer treatment and prevention—injection of therapeutics via the nipple. The procedure, demonstrated on mice, offers direct access to the most common origin of breast cancer, the milk ducts, and could be used to offer cancer therapy that spares healthy regions of the body.
“Local delivery of therapeutic agents into the breast, through intra-nipple injection, could diminish the side effects typically observed with systemic chemotherapy—where the toxic drugs pass through all of the tissues of the body,” said Dr. Silva Krause, one of the researchers behind the experiment, “It also prevents drug breakdown by the liver, for example, which can rapidly reduce effective drug levels.”
According to Silva, she and her colleagues have already begun experimentation in applying the method. “The authors have utilized this technique to inject a new nanoparticle-based therapeutic that inhibits a specific gene that drives breast cancer formation,” said Silva, “This targeted treatment was shown to prevent cancer progression in mice that spontaneously develop mammary tumors, [and] is currently in review in Science Translational Medicine.”
In order to better communicate their procedure, Silva and her colleagues decided to publish with JoVE. “Because the reader can actually watch the process and see how reagents, instruments, and animals are physically handled over time, the likelihood of reproducing this method in their own labs is greatly enhanced,” Silva said. “We believe this will help spread this new technical capability to many labs who are carrying out breast cancer research.”
About JoVE, the Journal of Visualized Experiments:
JoVE, the Journal of Visualized Experiments, is the first and only PubMed/MEDLINE-indexed, peer-reviewed journal devoted to publishing scientific research in a video format. Using an international network of videographers, JoVE films and edits videos of researchers performing new experimental techniques at top universities, allowing students and scientists to learn them much more quickly. JoVE has published video-protocols from an international community of nearly 8,000 authors in the fields of biology, medicine, chemistry, and physics.
