Showing 2401 - 2415Study Suggests Proteins Involved in Immunity May Be Responsible for Cancer-causing Mutations
A set of proteins involved in the body’s natural defenses produces a large number of mutations in human DNA, according to a study led by researchers at the National Institutes of Health. The findings, published in Nature Genetics, suggest that these naturally produced mutations are just as...
Colorectal Cancer Survivors Face Increased Risk of Developing Subsequent Cancers of Different Types
According to a new study, colorectal cancer survivors face an increased risk of developing subsequent primary cancers, particularly second colorectal cancers and small intestinal cancers. These findings, published online in Cancer, may help in the development of screening guidelines for patients...
Study Confirms Link Between High Blood Levels of Omega-3 Fatty Acids and Increased Risk of Aggressive Prostate Cancer
A second large, prospective study by scientists at Fred Hutchinson Cancer Research Center has confirmed the link between high blood concentrations of omega-3 fatty acids and an increased risk of prostate cancer. Study Details Published online in the Journal of the National Cancer Institute, the...
Critical Pathway in Cell Cycle May Lead to Cancer Development
A team of scientists at the Salk Institute for Biological Studies has identified why disruption of a vital pathway in cell cycle control leads to the proliferation of cancer cells. Their findings on telomeres, published today in Molecular Cell, suggest a potential target for preventive measures...
Aspirin May Help Prevent Cancer in Patients with Barrett’s Esophagus
Although aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to reduce cancer mortality by 20%, exactly why these drugs reduce the number of cancer incidences and deaths is not known. Now, a small longitudinal study of 13 patients with Barrett’s esophagus is...
Scientists Develop Mathematical Model to Predict Cancer Cells’ Resistance to Therapy
New research using mathematical models of different types of cancer—including melanoma, pancreatic, and colorectal—to determine the evolutionary dynamics of lesions in response to treatment is revealing why and how cancer cells resist targeted therapies. The study by Ivana Bozic, PhD,...
Phase II Trial Targeting Genetic Anomaly in Castration-resistant Metastatic Prostate Cancer Underway
A new clinical trial is testing whether targeting treatments to a genetic anomaly can lead to better treatments for castration-resistant metastatic prostate cancer. The trial, led by investigators at the University of Michigan Comprehensive Cancer Center, is being conducted at 11 sites throughout...
Study: Gold Nanoparticles Can Help Fight Ovarian Cancer
Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why and determined how to make the nanoparticles effective against ovarian cancer cells. The discovery is detailed in the current...
Emil ‘Tom’ Frei III, MD, Trailblazer in the Development of Combination Chemotherapy, Dies at 89
The pages of medical history are dog-eared with breakthroughs that have transformed medicine and saved lives. One of those dog-eared pages belongs to Emil Frei III, MD, known to his colleagues and friends as Tom. In the dawn of oncology, Dr. Frei, along with his associate, Emil Freireich, MD, did...
Delays in Diagnosis Worsen Outlook for Minority, Uninsured Pediatric Retinoblastoma Patients, Study Finds
When retinoblastoma is diagnosed in racial and ethnic minority children whose families don't have private health insurance, it often takes a more invasive, potentially life-threatening course than in other children, probably because of delays in diagnosis, researchers at Dana-Farber/Children's...
Genetic Risk Strategies Needed for Young, Black, Female Breast Cancer Patients, Moffitt Cancer Center Study Shows
Researchers at Moffitt Cancer Center and colleagues in Canada have published study results focused on black women younger than 50, a population disproportionately afflicted with and dying from early-onset breast cancer compared to their white counterparts. The research published in The...
Inherited Genetic Variations Have a Major Impact on Childhood Leukemia Risk
Humans have between 20,000 and 25,000 genes that carry instructions for assembling the proteins that do the work of cells. Work led by St. Jude Children’s Research Hospital found that children who inherit certain variations in four particular genes are at much higher risk of developing acute...
Infusion of Stem Cells and Specially Generated T-cells from Same Donor Improves Leukemia Survival
In a significant advance for harnessing the immune system to treat leukemias, researchers at Fred Hutchinson Cancer Research Center have successfully infused large numbers of donor-derived T cells specific for a key antileukemic antigen in order to prolong survival in high-risk and relapsed...
Obesity, Physical Inactivity Linked with Risk for Certain Molecular Subtype of Colorectal Cancer
An increasing body mass index (BMI) was associated with a higher risk for colorectal cancer with a specific molecular characteristic, and inversely, physical activity was linked to a decreased risk for that same cancer, according to data published in Cancer Research, a journal of the American...
NCI Researchers Identify Molecular Link between Metabolism and Breast Cancer
A protein associated with conditions of metabolic imbalance, such as diabetes and obesity, may play a role in the development of aggressive forms of breast cancer, according to new findings by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and their...
