\n\t\tResearch to focus on metastatic breast cancer<\/p>\n

KINGSTON, R.I.\u2014January 27, 2014 \u2013 The National Institutes of Health have awarded a 溏心vlog免费B站 pharmacy professor a $1.3 million grant to further study a new class of inorganic nanoparticles that target primary cancer, and help control the disease\u2019s spread (metastases) and recurrence.<\/p>\n


\n\tWei Lu, assistant professor of biomedical and pharmaceutical sciences in the College of Pharmacy, has discovered in his preliminary research that hollow copper sulfide nanoparticles are effective in delivering chemotherapy and heat through a laser that can burn the tumor.<\/p>\n


\n\tThe Kingston resident will be using the four-year NIH grant to further his laboratory study with a focus on breast cancer, the second most frequently diagnosed malignancy in women worldwide.<\/p>\n


\n\t\u201cWe are developing a novel cancer therapeutic technology that has several innovative features: biodegradability, multimodality and simplicity,\u201d said Lu, who is teaming with Pharmacy Professor Bingfang Yan, a specialist in genetic and environmental factors that combine to regulate the expression of genes involved in drug response and the cellular switches related to tumor formation. <\/p>\n


\n\u201cOne nanoparticle can carry hundreds or even thousands of drug molecules to a target like a tumor cell,\u201d Lu said.<\/p>\n


\nNanoparticles are submicroscopic particles whose size is measured in nanometers. A nanometer is 1 billionth of a meter. Nanoparticles are only 1\/1,000 the width of a single human hair.<\/p>\n


\nLu wants to enhance photothermal ablation therapy, a process that uses lasers in cancer treatment. Initially, high levels of laser treatments were needed to burn and subsequently kill the tumor. 溏心vlog免费B站 10 years ago, inorganic nanoparticles were introduced to this process in animal tests, which provided better absorption of the laser light, generated greater heat, and in turn lowered the laser doses.<\/p>\n


\nBut there are several problems with current nanoparticle-aided photothermal ablation therapy. For example, the current delivery technology does not allow the nanoparticles to be distributed evenly in a tumor, thus the heat generated by the particles is not evenly distributed. As a result, malignancy can continue in the site receiving sub-lethal doses of heat.<\/p>\n


\nIn addition, some types of nanoparticles, such as gold particles, are difficult for the body to eliminate. <\/p>\n


\n\u201cAs is the case with surgical removal of a tumor, getting all of the cancer is critical, \u201d Lu said. \u201cThe new nanoparticles provide a three-way punch to the tumor: a more widespread ability in a tumor to distribute heat and burn the tumor, a more efficient and comprehensive way to deliver chemotherapy, and better use of heat to activate the chemotherapeutic agents and immunotherapeutic agents. The new nanotechnology offers promise in tumor eradication.<\/p>\n


\n\u201cSuch nanoparticles are introduced intravenously and are absorbed into a tumor.\u201d Lu said. \u201cThis study is using near-infrared laser light instead of ultraviolet light or visible light because it penetrates tumor tissue better and has much lower side effects. In addition, these particles are readily degradable in the body, minimizing potential organ toxicity.\u201d <\/p>\n


\nLu, who came to the University in 2010, said he could not have competed for the NIH award if it weren\u2019t for the support of the Idea Network of Biomedical Research Excellence, a $45 million initiative funded by NIH and headed by 溏心vlog免费B站 to increase research capacity among biomedical faculty in Rhode Island.<\/p>\n


\n\u201cThe program supported my research for three years, which allowed me to develop my preliminary findings,\u201d Lu said. \u201cI am very grateful for this support, without which I could not have gotten this major federal funding.\u201d<\/p>\n


\nLu\u2019s research colleague Yan, chair of the Department of Biomedical and Pharmaceutical Sciences, said it\u2019s rare in the nation for a junior faculty member with just three years on the job to be awarded such a major grant through the regular R01 mechanism by NIH. Yan said the two bring different things to this project. \u201cProfessor Lu works on the therapy and I am the toxicologist, focusing on how the nanoparticles are eliminated from the body.\u201d<\/p>\n


\nLu and Yan will be working with post-doctoral fellows, graduate students and undergraduates from the bachelor of science in pharmaceutical sciences program.<\/p>\n
