Researchers at the University of Wisconsin-Madison School of Medicine and Public Health have identified a molecular mechanism that allows two powerful signaling pathways to interact and begin a process leading to colorectal tumors. http://www.physorg.com/news177359577.html Medicine & Health - Cancer Fri, 13 Nov 2009 18:50:02 EST news177359577 (PhysOrg.com) -- Scientists have devised an innovative way to disarm a key protein considered to be "undruggable," meaning that all previous efforts to develop a drug against it have failed. Their discovery, published in the November 12 issue of Nature, lays the foundation for a new kind of therapy aimed directly at a critical human protein -- one of a few thousand so-called transcription factors -- that could someday be used to treat a variety of diseases, especially multiple types of cancer. http://www.physorg.com/news177168648.html Medicine & Health - Cancer Wed, 11 Nov 2009 14:20:01 EST news177168648 (PhysOrg.com) -- Professor Robert Weiss has found that when two particular genes are inhibited, cancer cells are destroyed at a greater rate. The study is published in the Nov. 9 issue of PNAS. http://www.physorg.com/news177151857.html Medicine & Health - Cancer Wed, 11 Nov 2009 09:00:01 EST news177151857 (PhysOrg.com) -- A potential new drug for lung cancer has eliminated tumours in 50% of mice in a new study published today in the journal Cancer Research. In the animals, the drug also stopped lung cancer tumours from growing and becoming resistant to treatment. The authors of the research, from Imperial College London, are now planning to take the drug into clinical trials, to establish whether it could offer hope to patients with an inoperable form of lung cancer. http://www.physorg.com/news177083483.html Medicine & Health - Cancer Tue, 10 Nov 2009 13:52:13 EST news177083483 Although the chances of surviving advanced melanoma aren't very good with current therapies, some patients can live for years with cancer that has spread beyond the skin to other organs. Now it may be possible to identify which patients are more likely to survive by analyzing the activity of hundreds of genes involved in the immune response and gene proliferation, according to researchers at NYU Langone Medical Center. http://www.physorg.com/news177008484.html Medicine & Health - Cancer Mon, 09 Nov 2009 17:50:05 EST news177008484 (PhysOrg.com) -- MIT cancer biologists have identified a subpopulation of cells that can give rise to pancreatic cancer. They also found that tumors can form in other, more mature pancreatic cell types, but only when they are injured or inflamed, suggesting that pancreatic cancer can arise from different types of cells depending on the circumstances. http://www.physorg.com/news176386790.html Medicine & Health - Cancer Mon, 02 Nov 2009 12:20:27 EST news176386790 Researchers at the University of Michigan Comprehensive Cancer Center have discovered what leads to two genes fusing together, a phenomenon that has been shown to cause prostate cancer to develop. http://www.physorg.com/news176044773.html Medicine & Health - Cancer Thu, 29 Oct 2009 14:30:01 EST news176044773 Researchers at UT Southwestern Medical Center have eliminated non-small cell lung (NSCL) cancer in mice by using an investigative drug called BEZ235 in combination with low-dose radiation. http://www.physorg.com/news176033624.html Medicine & Health - Cancer Thu, 29 Oct 2009 11:14:18 EST news176033624 (PhysOrg.com) -- Nearly 80% of girls say that having the HPV vaccine makes them think twice about the risks of having sex, according to a University of Manchester study published in the British Journal of Cancer. http://www.physorg.com/news175857987.html Medicine & Health - Cancer Tue, 27 Oct 2009 11:00:01 EST news175857987 (PhysOrg.com) -- Preliminary results of an International investigation by the World Health Organization (WHO) suggest there may be a "significantly increased risk" of some types of brain tumors after use of mobile phones for a decade or more. http://www.physorg.com/news175853675.html Medicine & Health - Cancer Tue, 27 Oct 2009 10:50:02 EST news175853675 A recently discovered form of the protein that triggers blood clotting may play a key role in the molecular mechanisms leading to the growth of certain metastatic cancers, according to new research reported by an international team of scientists. http://www.physorg.com/news175791619.html Medicine & Health - Cancer Mon, 26 Oct 2009 16:01:41 EST news175791619 (PhysOrg.com) -- A protein that normally helps defend cells from infection can play a critical role in the development of lung cancer, according to MIT cancer biologists. http://www.physorg.com/news175414292.html Medicine & Health - Cancer Thu, 22 Oct 2009 07:14:06 EST news175414292 (PhysOrg.com) -- It was once thought that the two communities of cells within a cancerous breast tumor - fast-growing malignant cells and the normal cells that surround them - existed independently, without interaction. Then evidence emerged indicating that the normal-looking cells encouraged cells within the tumor to become malignant, but how the one community influenced the other wasn't known. http://www.physorg.com/news175353047.html Medicine & Health - Cancer Wed, 21 Oct 2009 15:00:05 EST news175353047 Researchers at the University of Pittsburgh School of Medicine and the National Cancer Institute (NCI), part of the National Institutes of Health, may be hot on the heels of a Holy Grail of cancer therapy: They have found a way to not only protect healthy tissue from the toxic effects of radiation treatment, but also increase tumor death. The findings appear today in Science Translational Medicine. http://www.physorg.com/news175355067.html Medicine & Health - Cancer Wed, 21 Oct 2009 15:00:03 EST news175355067 (PhysOrg.com) -- Cancer cells fueled by the mutant KRAS oncogene, which makes them notoriously difficult to treat, can be killed by blocking a more vulnerable genetic partner of KRAS, report scientists at the Dana-Farber Cancer Institute and the Broad Institute of Harvard and MIT. http://www.physorg.com/news175272905.html Medicine & Health - Cancer Tue, 20 Oct 2009 17:00:01 EST news175272905 A team of Northwestern University researchers, using an extremely sensitive tool based on nanotechnology, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy. http://www.physorg.com/news175188038.html Medicine & Health - Cancer Mon, 19 Oct 2009 18:20:05 EST news175188038 A series of studies have demonstrated that Chrysanthemum indicum possesses antimicrobial, antiinflammatory, immunomodulatory, and neuroprotective effects. Recently, much attention has been devoted to the anticancer activity of Chrysanthemum indicum, especially in hepatocellular carcinoma (HCC).

As a result, tissues deteriorate rapidly, which is generally fatal in these animals. In addition, the study provides supportive evidence for the use of inhibitors of ATR in cancer therapy. http://www.physorg.com/news174843234.html Medicine & Health - Cancer Thu, 15 Oct 2009 17:20:01 EST news174843234 (PhysOrg.com) -- A group of South Korean and American researchers has found studies of possible links between cell phones and brain tumors and other cancers vary in quality, and those suggesting there is little or no risk may have some bias. http://www.physorg.com/news174810947.html Medicine & Health - Cancer Thu, 15 Oct 2009 07:36:26 EST news174810947 (PhysOrg.com) -- A new study has provided genetic evidence for the first time that it is possible for a mother to transmit cancer to her unborn child via the placenta. http://www.physorg.com/news174733069.html Medicine & Health - Cancer Wed, 14 Oct 2009 09:58:40 EST news174733069 Researchers at UCLA's Jonsson Comprehensive Cancer Center showed for the first time that the loss or decreased expression of the tumor suppressor gene PTEN plays a central role in the malignant transformation of benign nerve tumors called neurofibromas into a malignant and extremely deadly form of sarcoma. http://www.physorg.com/news174645751.html Medicine & Health - Cancer Tue, 13 Oct 2009 10:20:01 EST news174645751 Researchers from Cold Spring Harbor Laboratory (CSHL) have uncovered a large, new cache of genes that act as built-in barriers against cancer.
