Hercepti\u00adn (also known as trastuzumab) \u2013 an effective HER2-inhibiting drug \u2014 was developed to treat HER2-positive breast cancer patients. However, even among early stages, more than 25 percent of patients developed resistance to the drug within as little as a year of treatment resulting in tumor relapse. Worse still, up to 75 percent of the late stage tumors resist Herceptin even if it is given in combination with chemotherapy.<\/p>\n<p>Hercepti\u00adn is still a top choice for treating HER2-positive breast cancer patients but drug resistance is a top concern. Despite the advancement in anti-breast cancer therapies, there is no effective treatment for drug-resistant tumor relapses.<\/p>\n<p>Working with Sudipta Seal, professor of <a href=\"http:\/\/mse.ucf.edu\">materials science and engineering<\/a> and director of the <a href=\"https:\/\/www.nanoscience.ucf.edu\">Nanoscience Technology Center<\/a> at UCF, Zhao found that preliminary experiments using cell culture have shown that Herceptin, if used in combination with cerium oxide nanoparticles, can kill Herceptin-resistant breast cancer cells very effectively. \u201cThis is very promising because the normal tissue-friendly cerium oxide nanoparticles may help Herceptin to eliminate the drug-resistant breast cancer tumors in vivo,\u201d\u00a0says Zhao.<\/p>\n<p>Zhao hopes that his research will lead to clinical trials in the future to help eradicate Herceptin-resistant breast cancer cells and save lives.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A UCF researcher will help develop a way to treat drug-resistant breast cancer
