A major study conducted at the Sahlgrenska Academy has now disproved theories of a viral cause for breast cancer and the brain tumor, glioblastoma. The study, which was based on over seven billion DNA sequences and which is published in Nature Communications, found no genetic traces of viruses in these forms of cancer. It has been scientifically proven that about 15 per cent of all cancer cases are the result of viral infection, but many researchers believe that even more cancers could be...

Protein Assists The Spread Of Breast Cancer
2012-01-18 06:02:54

Researchers have uncovered a protein that helps some breast cancer tumors to break through their surrounding cell matrix and spread to other tissues. The protein, called hepsin, is a protease which is a class of enzymes that cuts other proteins. Proteases can be successfully targeted by drugs, providing the opportunity to target hepsin as a possible new treatment. Co-author Zena Werb, PhD, a professor of anatomy at University of California - San Francisco, said “If we could delay...

PVRL4 (Nectin 4) is a receptor for measles virus Canadian researchers have discovered that a tumor cell marker is a receptor for measles virus, suggesting the possible use of measles virus to help fight cancer. Their findings appear in the Open Access journal PLoS Pathogens on August 25th. Viruses cause infection by attaching to specific proteins on cell surfaces called receptors. Dr. Chris Richardson of Dalhousie Medical School in Halifax, Nova Scotia, Canada and colleagues found that...

Delineation of the origin of the retrovirus known as XMRV from the genomes of laboratory mice indicates that the virus is unlikely to be responsible for either prostate cancer or chronic fatigue syndrome in humans, as has been widely published. The virus arose because of genetic recombination of two mouse viruses. Subsequent infection of lab experiments with XMRV formed the basis of the original association. Reporting in Science, Vinay Pathak, Ph.D., and his research team from the National...

(Ivanhoe Newswire) -- A genetically re-engineered herpes virus can hunt down and infect cancerous tumors, according to new research. Scientists also found this virus can then deliver genetic material that prompts cancers to secrete a biomarker and reveal their presence. Researchers at Cincinnati Children's Hospital Medical Center conducted the study in preclinical mouse models. They say the technology has the potential to improve cancer diagnosis by allowing the disease to be caught at...

By: Rhonda Craig, Ivanhoe Health Correspondent (Ivanhoe Newswire) --Viruses that are a natural part of human genome, may be linked to a deadly progressive neurodegenerative disease. New research shows that a retrovirus that inserted itself into the human genome thousands of years ago may be responsible for some cases of Lou Gherig's disease (also known as amyotrophic lateral sclerosis or ALS). "The human genome has acquired several retroviruses over millions of years. In fact they constitute...

A study by researchers at Tufts University School of Medicine, the Sackler School of Graduate Biomedical Sciences at Tufts, and Tufts Medical Center improves our current understanding of the origins of breast cancer. The researchers propose a new model for breast cell differentiation that identifies two populations of progenitor cells, one of which appears to be the cell of origin for luminal-like breast cancer, the most common form of the disease. The study, published in the January 19 issue...

Scientists from the Kimmel Cancer Center at Jefferson have discovered a possible way for malignant breast tumors to be identified, without the need for a biopsy. The findings were published online ahead of print in the Journal of Nuclear Medicine. Current imaging modalities miss up to 30% of breast cancers and cannot distinguish malignant tumors from benign tumors, thus requiring invasive biopsies. Approximately 5.6 million biopsies performed in the United States find only benign lesions....

Results of transgenic mouse study directly applicable to human breast cancer tumor study Sanford Barsky, M.D., who holds faculty positions at the University of Nevada School of Medicine as chair of the pathology department and Nevada Cancer Institute chief of pathology, is part of a team that has a paper on transgenic mouse mammary tumors with direct relevance to human breast cancer published in the October 22 issue of the scientific journal Nature. The article, "Pten in stromal fibroblasts...
