Colon cancer study backs blood stool screening test (2/23/2012 12:44:32 AM) NEW YORK (Reuters Health) - Although colon cancer screening is recommended by many organizations, less clear is which method is best to detect tumors and precancerous lesions. A new study in the New England Journal of Medicine suggests that a relatively inexpensive and non-invasive test may be just as effective as a colonoscopy. Strengthening The Intestinal Barrier May Prevent Cancer In The Rest Of The Body (2/22/2012 12:04:14 PM) A leaky gut may be the root of some cancers forming in the rest of the body, a new study published online Feb. 21 in PLoS ONE by Thomas Jefferson University researchers suggests. It appears that the hormone receptor guanylyl cyclase C (GC-C) - a previously identified tumor suppressor that exists in the intestinal tract - plays a key role in strengthening the body's intestinal barrier, which helps separate the gut world from the rest of the body, and possibly keeps cancer at bay. Without the receptor, that barrier weakens. A team led by Scott Waldman, M.D., Ph.D... Possible New Target For Cancer Therapy - Energy Network Within Cells (2/22/2012 9:24:19 AM) Mitochondria, tiny structures within each cell that regulate metabolism and energy use, may be a promising new target for cancer therapy, according to a new study. Manipulation of two biochemical signals that regulate the numbers of mitochondria in cells could shrink human lung cancers transplanted into mice, a team of Chicago researchers report in the journal FASEB. Within each cell, mitochondria are constantly splitting in two, a process called fission, and merging back into one, called fusion... Early Cancer Detection Via New Blood Test: Research In The Early Stages Of Clinical Trials (2/22/2012 9:24:19 AM) A simple blood test is being developed by researchers at Ben-Gurion University of the Negev (BGU) and Soroka University Medical Center in Beer-Sheva, Israel that may provide early detection of many types of cancer. Prof. Kapelushnik of BGU's Faculty of Health Sciences and his team developed a device that illuminates cancer cells with less than a teaspoon of blood. The test uses infrared light to detect miniscule changes in the blood of a person who has a cancerous growth somewhere, even before the disease has spread... Prostate Cancer Progression Driven By Telomere Failure, Telomerase Activation (2/22/2012 9:24:19 AM) Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those caps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell. In a strain of mice engineered to develop prostate cancer, all mice that went through this two-step process developed lethal cancer and 25 percent had the disease spread to the spine. Two groups of mice that avoided this cycle developed only precancerous lesions or localized prostate cancer... Cancer Cells Destroyed By Blocking Telomerase But Resistance, Progression Provoked (2/22/2012 9:24:19 AM) Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in Cell. "Telomerase is overexpressed in many advanced cancers, but assessing its potential as a therapeutic target requires us to understand what it does and how it does it," said senior author Ronald DePinho, M.D., president of The University of Texas MD Anderson Cancer Center... Potential For Development Of Tailor-Made Anticancer Agents Following Mapping Of Protein Inhibitors (2/22/2012 9:24:19 AM) A team of researchers at Karolinska Institutet has generated a map over the effects of small drug-like molecules on PARP1 and other similar proteins in the body. This map may explain the mechanism behind putative side effects of the so-called PARP inhibitors, and can play an important role in the development of novel tailor-made cancer drugs. The study is presented in the journal Nature Biotechnology, and will hopefully contribute to new cancer therapies with fewer detrimental side effects. PARP1 is a protein with enzymatic activity that governs repair of DNA damage in our cells... Reformulated Imatinib Eliminates Morphine Tolerance In Lab Studies (2/22/2012 9:24:19 AM) By reformulating the common cancer drug imatinib (Gleevec®), researchers have eliminated morphine tolerance in rats - an important step toward improving the effectiveness of chronic pain management in patients, according to researchers at The University of Texas MD Anderson Cancer Center. Narcotics such as morphine are a mainstay of chronic pain treatment. Over time, tolerance to the pain-relieving effects of these drugs can develop, requiring increasing doses to control pain. In some cases, narcotics become ineffective...

Study Details On-off Switch That Promotes Or Suppresses Breast Cancer (2/20/2012 9:24:20 AM) Signals can tell cells to act cancerous, surviving, growing and reproducing out of control. And signals can also tell cells with cancerous characteristics to stop growing or to die. In breast cancer, one tricky signal called TGF-beta does both - sometimes promoting tumors and sometimes suppressing them. A University of Colorado Cancer Center study recently published in the journal Oncogene details how tumors may flip the TGF-beta signalling switch, allowing doctors to delete the pathway entirely when it promotes tumors, and leave it intact when it's still working to suppress them... New Guiding Principles For Cancer Genomics: Understanding Chromosome Reshuffling, Looking To The Genome's 3D Structure (2/20/2012 9:24:20 AM) That our chromosomes can break and reshuffle pieces of themselves is nothing new; scientists have recognized this for decades, especially in cancer cells.

Anti-Angiogenic Drugs May Be Effective Against New Subtype Of Ovarian Cancer (2/16/2012 11:04:16 AM) Scientists at Dana-Farber Cancer Institute have identified a subtype of ovarian cancer able to build its own blood vessels, suggesting that such tumors might be especially susceptible to "anti-angiogenic" drugs that block blood vessel formation. In a study published in the online journal PloS ONE, the investigators estimate that the subtype may account for a third of all serous ovarian cancers, a common cancer of the surface of the ovaries... Molecule Is Important Step Towards Creating Drugs That Can Go After Rogue DNA Directly (2/16/2012 11:04:16 AM) Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported. It's an important step along the path to someday creating drugs that can go after rogue DNA directly. Such drugs would be revolutionary in the treatment of genetic diseases, cancer or retroviruses such as HIV, which incorporate viral DNA directly into the body's DNA... Biosensors Inspired By Nature (2/16/2012 11:04:16 AM) Over their 3.8 billion years of evolution, living organisms have developed countless strategies for monitoring their surroundings. Chemists at UC Santa Barbara and University of Rome Tor Vergata have adapted some of these strategies to improve the performance of DNA detectors. Their findings may aid efforts to build better medical diagnostics, such as improved HIV or cancer tests. Their research is described in an article published this week in the Journal of the American Chemical Society. Nature often serves as a source of inspiration for the development of new technologies... Breast Cancer Cells Transformed Into Cancer Stem Cells By Radiation Treatment (2/16/2012 10:04:08 AM) Breast cancer stem cells are thought to be the sole source of tumor recurrence and are known to be resistant to radiation therapy and don't respond well to chemotherapy. Now, researchers with the UCLA Department of Radiation Oncology at UCLA's Jonsson Comprehensive Cancer Center report for the first time that radiation treatment - despite killing half of all tumor cells during every treatment - transforms other cancer cells into treatment-resistant breast cancer stem cells. The generation of these breast cancer stem cells counteracts the otherwise highly efficient radiation treatment... Pre-Clinical Study Shows Delay In Tumor Growth And Prolonged Survival Time When Chemotherapy Combined With Immunotherapy (2/16/2012 10:04:08 AM) An international team of scientists in Japan, Switzerland, and the United States has confirmed that combining chemotherapy and immunotherapy in cancer treatment enhances the immune system's ability to find and eliminate cancer cells, even when the cancer-associated proteins targeted by the immune system are hidden behind the cancer cell membrane. In a study published in Cancer Research by Noguchi et al...

New Research Into Immune Tolerance Studies The Sensing Of Self And Non-Self (2/15/2012 10:24:45 AM) At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens). The system is far from foolproof. Cancer cells can undergo unchecked proliferation, producing self-antigens that are tolerated by the immune system, rather than being targeted for destruction. At the opposite extreme, a range of so-called autoimmune disorders can result when healthy cells in the body are misidentified as hazards... Increased Risk Of Testicular Cancer When Fetus Exposed To Radiation (2/15/2012 9:24:06 AM) Male fetuses of mothers that are exposed to radiation during early pregnancy may have an increased chance of developing testicular cancer, according to a study in mice at The University of Texas MD Anderson Cancer Center.
