Marker identifies tumors unable to repair DNA damage by platinum agents Scientists from Brigham and Women's Hospital and Dana-Farber Cancer Institute and their colleagues have found a genetic marker that predicts which aggressive "triple negative" breast cancers and certain ovarian cancers will likely respond to platinum-based chemotherapies. The marker, found on chromosomes within the cancer cells, could lead to a test for identifying patients whose cancers could be effectively treated...

Opioid drugs used to relieve pain in postoperative and chronic cancer patients may stimulate the growth and spread of tumors, according to two studies and a commentary in the 2012 annual Journal Symposium issue of Anesthesiology, the academic journal of the American Society of Anesthesiologists. "Epidemiologic findings suggest that the type of anesthesia we do for cancer surgery influences recurrence rate, and laboratory studies demonstrate that opioids influence tumor progression and...

SAN FRANCISCO, March 20, 2012 /PRNewswire/ -- Jennerex, Inc., a private clinical-stage biotherapeutics company focused on the development and commercialization of first-in-class targeted oncolytic virus products for cancer, today announced that the first patient has been treated in a Phase 1/2 clinical trial of JX-594 in patients with metastatic colorectal cancer who have become refractory to chemotherapy and are either refractory to or ineligible for cetuximab. The two-arm,...

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus. The strategy, called cancer immunotherapy, uses a genetically engineered version of the vesicular stomatitis virus to deliver a broad spectrum of genes derived from melanoma cancer cells directly into tumors. In early studies, 60 percent of tumor-burdened mice were cured in fewer than three months and...

The authors, from Oscar Fernandez Capetillo's group, have identified this double-edged property in the gene Chk1, an established tumor suppressor Can a gene simultaneously protect against cancer and favor its growth? Researchers at the Spanish National Cancer Research Centre have discovered a gene with this double-edged property and suspect there may be many more that share it. In the words of Oscar Fernandez Capetillo, head of the group responsible for the study, this gene "can be both...

In the news release, Running the New York City Half Marathon in Hopes of Finding Treatments for Neurofibromatosis, issued 13-Mar-2012 by Children's Tumor Foundation over PR Newswire, the source should read "Children's Tumor Foundation" rather than "Children's Brain Tumor Foundation" as incorrectly transmitted by PR Newswire. The complete, corrected release follows: Running the New York City Half Marathon in Hopes of Finding Treatments for Neurofibromatosis NEW YORK, March 13,...

NEW YORK, March 13, 2012 /PRNewswire-USNewswire/ -- Imagine being told by a doctor, "Your child has a genetic disorder that will affect the rest of her life. There are few medical treatment options and there is no cure." (Logo: http://photos.prnewswire.com/prnh/20120117/MM37181LOGO) Sylvia Colon experienced just such a circumstance when her daughter, Chloe, was diagnosed with neurofibromatosis type 2 (NF2) at age 13. Neurofibromatosis (NF) causes tumors to grow along nerves throughout...

Purdue University researchers have created a new imaging technology that reveals subtle changes in breast tissue, representing a potential tool to determine a woman's risk of developing breast cancer and to study ways of preventing the disease. The researchers, using a special "3-D culture" that mimics living mammary gland tissue, also showed that a fatty acid found in some foods influences this early precancerous stage. Unlike conventional cell cultures, which are flat, the 3-D cultures...

Persistent protein expression may explain why tumors return after therapy in glioblastoma patients, according to a study published on March 5th in the Journal of Experimental Medicine. Current therapy for glioblastoma, the most prevalent malignant brain tumor in adults, includes targeting a protein called VEGF, which promotes the growth of blood vessels to the tumor. Unfortunately, in most glioblastoma patients treated with anti-VEGF drugs, tumors return shortly after treatment. Through...

2 studies published online today in the same issue of journal Cell BGI, the world's largest genomics organization, developed single-cell genome sequencing technology and published two research papers for cancer single-cell sequencing in the research journal Cell. In the papers, which were published today in the same issue of Cell, BGI researchers applied their new single-cell sequencing (SCS) method to identify the genetic characteristics of essential thrombocythemia (ET, a kind of blood...
