Researcher Discovers Homing Device That Attracts Melanoma To The Brain
9/21/2012
The process of metastasis, by which cancer cells travel from a tumor site and proliferate at other sites in the body, is a serious threat to cancer patients. According to the National Cancer Institute, most recurrences of cancer are metastases rather than "new" cancers. Virtually all types of cancer can spread to other parts of the body, including the brain...
A Few 'Hotspots' On The Human Genome Revealed By Diseases Of Aging Map
9/21/2012
Researchers have long known that individual diseases are associated with genes in specific locations of the genome. Genetics researchers at the University of North Carolina School of Medicine now have shown definitively that a small number of places in the human genome are associated with a large number and variety of diseases...
New cancer drugs must be thoroughly tested in preclinical models, often in mice, before they can be offered to cancer patients for the first time in phase I clinical trials. Key components of this process include pharmacokinetic and pharmacodynamic studies, which evaluate how the drug acts on a living organism...

Researchers Clarify Catalysis Mechanism Of Cell Growth Protein Ras
9/20/2012
PNAS: Proteins bring tension to the phosphate chain Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists at the Ruhr-Universität Bochum led by Prof. Dr...
Assessment Of HPV DNA Alone Insufficient To Identify HPV-Driven Head And Neck Cancers
9/20/2012
Human papillomavirus (HPV) DNA positivity alone, particularly when assessed using polymerase chain reaction methods, is a poor biomarker for HPV-driven head and neck cancers, according to two studies published in Cancer Research, a journal of the American Association for Cancer Research...

Contamination Led To Erroneous Link Between XMRV And Prostate Cancer
9/20/2012
A once-promising discovery linking prostate cancer to an obscure retrovirus derived from mice was the result of an inadvertent laboratory contamination, a forensic analysis of tissue samples and lab experiments - some dating back nearly a decade - has confirmed...
