One of the challenges in treating cancer, whether using nanotechnology or not, is that tumors can often be inaccessible to the therapies designed to kill them. Mostafa El-Sayed, of the Georgia Institute of Technology, and his colleagues are attempting to overcome this obstacle by designing drug-loaded gold nanorods that attract the attention of tumor-associated immune cells known as macrophages. The researchers believe that these macrophages will then deliver the nanorods to the tumors, crossing the normally impermeable blood-brain barrier to do so. http://phys.org/news264409376.html Nanotechnology Fri, 17 Aug 2012 08:05:14 EST news264409376 One in eight women in the United States will develop breast cancer. Of those, many will undergo surgery to remove the tumor and will require some kind of breast reconstruction afterward, often involving implants. Cancer is an elusive target, though, and malignant cells return for as many as one-fifth of women originally diagnosed, according to the American Cancer Society. http://phys.org/news251722553.html Nanotechnology Fri, 23 Mar 2012 11:56:21 EST news251722553 In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, which the researchers call "CAMo," for coherent angular motion, is necessary for the cells to form spheres. Without CAMo, the cells do not form spheres, which can lead to random motion, loss of structure and malignancy. http://phys.org/news246803318.html Biology Thu, 26 Jan 2012 12:31:14 EST news246803318 Researchers have found that a protein linked to cell division and migration and tied to increased cell proliferation in ovarian tumors is also present at high levels in breast cancer specimens and cell lines. The protein, dubbed "UNC-45A," was also determined to be more active in breast cancer cells than in normal breast cells. http://phys.org/news235320908.html Biology Thu, 15 Sep 2011 15:55:52 EST news235320908 (PhysOrg.com) -- Last month, Dr. Michael Stadler and his Computational Biology group at the Friedrich Miescher Institute for Biomedical Research became a member laboratory of the Swiss Institute of Bioinformatics. This is in well-deserved recognition of the widely appreciated expertise in computational biology residing in Michael Stadler and his FMI bioinformatics team. http://phys.org/news232104807.html Biology Tue, 09 Aug 2011 10:40:01 EST news232104807 The recently identified TRIM24 protein plays an active role in pushing normal breast cells into rapid cell proliferation and, potentially, into breast cancer. http://phys.org/news211642451.html Medicine & Health Wed, 15 Dec 2010 13:34:42 EST news211642451 It is well established that exposure to ionizing radiation can result in mutations or other genetic damage that cause cells to turn cancerous. Now a new study led by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has revealed another way in which radiation can promote cancer development. Working with cultures of human breast cells, the researchers discovered that radiation exposure can alter the environment surrounding the cells so that future cells are more likely to become cancerous. http://phys.org/news192978184.html Medicine & Health Thu, 13 May 2010 14:03:26 EST news192978184 Time-lapsed video of individual breast tissue cells reveals a never-before-seen event in the life of a cell: a protein that cycles between two major compartments in the cell. The results give researchers a more complete view of the internal signals that cause breast tissue cells to grow, events that go awry in cancer and are targets of drug development. http://phys.org/news178879135.html Biology Tue, 01 Dec 2009 08:39:58 EST news178879135 (PhysOrg.com) -- Researchers at the University of Cincinnati have documented that the brain hormone serotonin is made in human breast cancer cells and functions abnormally, contributing to malignant growth. http://phys.org/news178308579.html Medicine & Health Tue, 24 Nov 2009 18:20:02 EST news178308579 Researchers at Georgetown University Medical Center (GUMC) are voicing alarm that drugs to treat a wide variety of allergies, asthma and autoimmune diseases now in human clinical trials may errantly spur development of breast tumors. http://phys.org/news174804357.html Medicine & Health Thu, 15 Oct 2009 06:00:43 EST news174804357 (PhysOrg.com) -- Scientists are close to discovering how normal breast cells become cancerous, according to research by Cambridge scientists published today. http://phys.org/news174053855.html Medicine & Health Tue, 06 Oct 2009 13:18:49 EST news174053855 Vaccinating women against the human papillomavirus (HPV) may prevent some forms of breast cancer and save tens of thousands of lives each year, new Australian research suggests. http://phys.org/news171194323.html Medicine & Health Thu, 03 Sep 2009 10:59:30 EST news171194323 Excess amounts of a naturally fluorescent molecule found in all living cells could serve as a natural biomarker for cancer, according to bioengineers. http://phys.org/news157889633.html Chemistry Thu, 02 Apr 2009 11:14:24 EST news157889633
