A new research report appearing in the October 2011 issue of The FASEB Journal shows that resveratrol, the "healthy" ingredient in red wine, stops breast cancer cells from growing by blocking the growth effects of estrogen. This discovery, made by a team of American and Italian scientists, suggests for the first time that resveratrol is able to counteract the malignant progression since it inhibits the proliferation of hormone resistant breast cancer cells. This has important implications for the treatment of women with breast cancer whose tumors eventually develop resistance to hormonal therapy. http://medicalxpress.com/news/2011-09-red-wine-ingredient-resveratrol-breast.html Cancer Thu, 29 Sep 2011 10:17:17 EST news236510225 Johns Hopkins researchers have devised a protein "switch" that instructs cancer cells to produce their own anti-cancer medication. http://medicalxpress.com/news/2011-09-protein-cancer-cells-tiny-chemotherapy.html Cancer Fri, 23 Sep 2011 11:47:56 EST news235997150 A nondisease-causing virus kills human breast cancer cells in the laboratory, creating opportunities for potential new cancer therapies, according to Penn State College of Medicine researchers who tested the virus on three different breast cancer types that represent the multiple stages of breast cancer development. http://medicalxpress.com/news/2011-09-virus-breast-cancer-cells-laboratory.html Cancer Thu, 22 Sep 2011 11:31:52 EST news235909833 Researchers are working to discover how genes interact with each other to lead to cancer progression.

Scott Cancer Center, has found that a protein discovered by his laboratory can inhibit the growth of breast cancer cells. The research will be published September 14, 2011 online in the Journal of the National Cancer Institute. http://medicalxpress.com/news/2011-09-protein-suppress-breast-cancer-growth.html Cancer Wed, 14 Sep 2011 16:30:53 EST news235236613 Gene therapy delivered directly to a particularly stubborn type of breast cancer cell causes the cells to self-destruct, lowers chance of recurrence and helps increase the effectiveness of some types of chemotherapy, researchers at The University of Texas MD Anderson Cancer Center reported in the Sept. 13 edition of Cancer Cell. http://medicalxpress.com/news/2011-09-gene-therapy-breast-cancer-stem.html Cancer Mon, 12 Sep 2011 12:24:55 EST news235049043 (Medical Xpress) -- In lab studies, researchers at Virginia Commonwealth University Massey Cancer Center have effectively reprogrammed cells of the innate and adaptive immune system to overcome a key cancer defense mechanism and develop long-lasting memory to reject breast cancer cells and guard against tumor relapse. http://medicalxpress.com/news/2011-09-barrier-cancer-immunotherapy.html Cancer Fri, 02 Sep 2011 09:26:40 EST news234174367 The most common breast cancer uses the most efficient, powerful food delivery system known in human cells and blocking that system kills it, researchers report. http://medicalxpress.com/news/2011-08-aims-starve-breast-cancer-cells.html Cancer Mon, 29 Aug 2011 11:33:36 EST news233836392 Using human breast cancer cells and the protein that causes fireflies to glow, a Johns Hopkins team has shed light on why some breast cancer cells become resistant to the anticancer effects of the drug tamoxifen. The key is a discovery of two genetic "dimmer switches" that apparently control how a breast cancer gene responds to the female hormone estrogen. http://medicalxpress.com/news/2011-07-breast-cancers-sensitivity-estrogen.html Cancer Wed, 27 Jul 2011 11:50:01 EST news230984527 The first roadmap to mathematical modeling of a powerful basic "decision circuit" in breast cancer has been developed and published in Nature Reviews Cancer. http://medicalxpress.com/news/2011-06-roadmap-published-dynamic-estrogen-breast.html Cancer Thu, 16 Jun 2011 11:01:37 EST news227440875 Whitehead Institute researchers have identified signals from breast epithelial cells that can induce those cells to transition to and maintain a mesenchymal and stem cell-like cell state that imbues both normal and cancer cells with a greater ability to migrate and self-renew. Interrupting these signals strips the cells of the migratory, invasive and self-renewal abilities used by cancer stem cells to seed new tumors. http://medicalxpress.com/news/2011-06-pathways-vulnerability-breast-cancer-stem.html Medical research Thu, 09 Jun 2011 13:14:15 EST news226844025 A multicenter clinical trial led by a researcher at the University of Maryland Marlene and Stewart Greenebaum Cancer Center will evaluate a new approach to treat triple-negative breast cancer, an often-aggressive type of cancer that is more common among African-Americans and young women. The study will help researchers determine if an experimental drug, entinostat, can reprogram tumor cells to express a protein called an estrogen receptor to make them sensitive to hormone therapy. http://medicalxpress.com/news/2011-06-clinical-trial-approach-triple-negative-breast.html Cancer Thu, 02 Jun 2011 14:24:39 EST news226243467 While it is already known that breast cancer cells create the conditions for their own survival by communicating their needs to the healthy cells that surround them, Australian researchers have identified a new way of turning off that cellular cross talk. http://medicalxpress.com/news/2011-06-silencing-deadly-conversation-breast-cancer.html Cancer Thu, 02 Jun 2011 09:27:12 EST news226225621 Scientists at Dana-Farber Cancer Institute have identified an overactive network of growth-spurring genes that drive stem-like breast cancer cells enriched in triple-negative breast tumors, a typically aggressive cancer that is highly resistant to current therapies. http://medicalxpress.com/news/2011-06-scientists-overactive-genes-aggressive-breast.html Cancer Wed, 01 Jun 2011 12:14:51 EST news226149269 A recently discovered enzyme drives the production of a potent form of estrogen in human breast cancer tissue, researchers from the University of Illinois at Chicago College of Medicine have found. http://medicalxpress.com/news/2011-05-enzyme-breast-cancer-growth.html Cancer Wed, 18 May 2011 16:14:24 EST news224954046 An international research team led by Dr. Tak Mak, Director, The Campbell Family Institute for Breast Cancer Research at Princess Margaret Hospital (PMH), has discovered a new aspect of "metabolic transformation", the process whereby tumour cells adapt and survive under conditions that would kill normal cells. http://medicalxpress.com/news/2011-05-cancer-scientists-breast-cells-environmental.html Cancer Sun, 15 May 2011 11:38:25 EST news224678285 A UT Southwestern Medical Center researcher has identified the most comprehensive measurement to date of estrogen's effect on breast cancer cells, showing for the first time how immediate and extensive the effect is. http://medicalxpress.com/news/2011-05-far-reaching-effects-estrogen-breast-cancer.html Cancer Thu, 05 May 2011 13:02:51 EST news223819346 Measuring the transfer of tiny amounts of energy from one protein to another on breast cancer cells has given scientists a detailed view of molecular interactions that could help predict how breast cancer patients will respond to particular therapies. http://medicalxpress.com/news/2011-05-protein-snapshots-reveal-clues-breast.html Cancer Thu, 05 May 2011 09:54:12 EST news223807994 A protein capable of halting the spread of breast cancer cells could lead to a therapy for preventing or limiting the spread of the disease. http://medicalxpress.com/news/2011-05-protein-cancer.html Cancer Wed, 04 May 2011 15:48:34 EST news223742896 Most breast cancers are fueled by estrogen, and anti-estrogenic agents often work for a time to control the cancers.
