A Role For DNA Replication Protein In Mitosis, Cancer
5/14/2012
The foundation of biological inheritance is DNA replication - a tightly coordinated process in which DNA is simultaneously copied at hundreds of thousands of different sites across the genome. If that copying mechanism doesn't work as it should, the result could be cells with missing or extra genetic material, a hallmark of the genomic instability seen in most birth defects and cancers...
Novel Approach To Stimulate Immune Cells Has Potential For Treatment Of Immune Diseases And Cancer
5/14/2012
Researchers at Rutgers University have uncovered a new way to stimulate activity of immune cell opiate receptors, leading to efficient tumor cell clearance...
Fight Against Melanoma May Be Aided By Cell Signaling Discovery
5/14/2012
The human body does a great job of generating new cells to replace dead ones but it is not perfect. Cells need to communicate with or signal to each other to decide when to generate new cells. Communication or signaling errors in cells lead to uncontrolled cell growth and are the basis of many cancers...
Colon Cancer And Economic Theory In Health Care
5/14/2012
A study of 7,424 privately insured colon cancer patients found that managed care presence in the market and hospital competition increased the likelihood laparoscopic surgery to treat colon cancer lowered costs, a national team of researchers led by a professor at the George Washington University School of Public Health and Health Services reported in the journal Cancer...
Researchers Describe A New Target For Developing Anti-Angiogenic And Anti-Tumoral Therapies
5/14/2012
Researchers from the Spanish National Cancer Research Centre (CNIO), led by Jorge L. MartÃnez-Torrecuadrada from the Proteomics Unit, have demonstrated that the antibody-based blocking of ephrinB2, a protein involved in angiogenesis and lymphoangiogenesis, may represent an effective strategy for the development of antiangiogenic and antitumoural therapies...
New Twist On Ancient Math Problem Could Improve Medicine, Microelectronics
5/14/2012
A hidden facet of a math problem that goes back to Sanskrit scrolls has just been exposed by nanotechnology researchers at the University of Michigan and the University of Connecticut...
How To Hit The Treatment Target And Breathe Without Causing Collateral Damage During Radiotherapy
5/14/2012
Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumour, or a potentially toxic over-dose to the surrounding healthy tissue...
Genetic Mosaicism Linked To Aging And Cancer
5/13/2012
Two new studies have linked a condition known as genetic mosaicism to aging and cancer. They suggest presence of the condition, the risk of which increases with age, could be a biomarker for early detection of cancer and other chronic diseases...
Inflammation Related To GERD May Contribute To Esophageal Cancer Risk
5/13/2012
Inflammation might be an important factor in the progression from reflux to esophageal cancer, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association...
Gene Expression By Ultraviolet
5/13/2012
Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater precision when studying gene function, and could lead to targeted therapies for diseases like cancer...
