New therapeutic target may improve treatment for brain cancer

The research will be presented at the American Society for Pharmacology and Experimental Therapeutics (ASPET) Annual Meeting during Experimental Biology 2015. Monteagudo’s research indicates a new possible chemotherapeutic target for treating GBM: transglutaminase 2 (TG2), a multifunctional protein that can regulate cell adhesion and motility. Given these documented functions of TG2, Monteagudo and her colleagues in the laboratory of Gail Johnson, Ph.D., at the University of Rochester, were interested in determining if TG2 played an important role in GBM cell growth. …

Antiangiogenic treatment improves survival rates in animal model of ovarian cancer

Now research in an animal model finds that a novel combination therapy, which couples low-dose chemotherapy with an antiangiogenic treatment, resulted in better survival rates compared with standard therapy. Led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and the University of Guelph, the findings show that the agent, 3TSR, not only led to tumor regression, but also improved tumor blood flow and enabled more efficient delivery of much smaller and less toxic doses of chemotherapy. The study currently appears online in The Journal of the Federation of American Societies for Experimental Biology (FASEB) and will be published in the February 2015 print issue. …

New rules for anticancer vaccines

As cancer cells divide, they accumulate random mistakes (mutations). This process creates new versions of proteins, some of which are recognized as foreign invaders by immune cells called T cells, prompting the cells to attack and eliminate the cancer cells. With our current ability to identify all of the mutations in a patient’s cancer and to understand which protein sequences can be recognized by T cells, scientists can now predict which mutations will result in new T cell targets (called “neoepitopes”)…

Experimental regimen tested for small cell lung cancer

Small cell lung cancer, which includes oat cell carcinoma, is a more aggressive disease than other types of lung cancer and often is more advanced at the time of diagnosis. Smoking is the most common cause of the diagnosis and can be diagnosed even decades after an individual has quit. At advanced stages of the disease, it is incurable in the vast majority of patients, with a median survival less than 12 months. Mita said that following a diagnosis of small cell lung cancer, most patients opt for immediate chemotherapy using the standard-of-care chemotherapy’s etoposide and cisplatin — two drugs developed more than three decades ago…

Battling defiant leukemia cells

Chronic myeloid leukemia (CML) is an aggressive cancer of the blood that is often treated with a drug called Imatinib (a.k.a. Gleevec). Although Gleevec is highly effective, some cancer cells can develop resistance to the drug. The mechanism that drives this resistance is not completely understood, but there is evidence that cancerous stem-like cells are particularly resistant and help to perpetuate disease. …

Targeting errant immune system enzyme kills myelodysplastic cells

Reporting their results July 8 in Cancer Cell, researchers say their successful laboratory tests in human MDS cells and mouse models of MDS provide a molecular target for designing new drugs to battle a syndrome with few effective treatments. "There is an urgent need to develop new targeted therapies that can eliminate MDS-initiating clone cells and provide a durable therapeutic response," said Daniel Starczynowski, PhD, lead researcher and a member of the Division of Experimental Hematology and Cancer Biology at Cincinnati Children’s Hospital Medical Center…
