Colorectal tumor risk associated with gut microbes
11/07/2013
Transferring the gut microbes from a mouse with colon tumors to germ-free mice makes those mice prone to getting tumors as well, according to the results of a study published in mBio®, the online open-access journal of the American Society for Microbiology. The work has implications for human health because it indicates the risk of colorectal cancer may well have a microbial component...
A variety of cancers destroyed by drug combination therapy
11/07/2013
Results from a recent preclinical study have shown that a new drug combination therapy being developed at Virginia Commonwealth University Massey Cancer Center effectively killed colon, liver, lung, kidney, breast and brain cancer cells while having little effect on noncancerous cells...
Statistical model teaches machines to detect breast cancer
11/07/2013
Software that can recognize patterns in data is commonly used by scientists and economics. Now, researchers in the US have applied similar algorithms to help them more accurately diagnose breast cancer. The researchers outline details in the International Journal of Medical Engineering and Informatics...
Light-scattering techniques reveal the cause of sickle cell disease
11/07/2013
In sickle cell disease, hemoglobin - the oxygen-carrying component of blood - forms fibers that stiffen red blood cells and cause life-threatening symptoms. Using light-scattering techniques to study the detailed thermodynamics of this process, researchers reporting in the Biophysical Journal, a Cell Press publication, have determined the strength of the forces that hold these fibers intact...
Rampaging tumor cells
11/07/2013
Tumors become highly malignant when they acquire the ability to colonize other tissues and form metastases. LMU researchers have identified a factor that promotes metastasis of colon tumors - and presents a possible target for therapy...
'Second opinion' in breast tumor diagnosis offered by computer-aided image analysis
11/07/2013
Researchers at the University of Chicago are developing computer-aided diagnosis (CADx) and quantitative image analysis (QIA) methods for mammograms, ultrasounds and magnetic resonance images (MRIs) to identify specific tumor characteristics, including size, shape and sharpness, said lead researcher Maryellen Giger, A.N...
Researchers at the University of Michigan Comprehensive Cancer Center have identified a type of mutation that develops after breast cancer patients take anti-estrogen therapies. The mutations explain one reason why patients often become resistant to this therapy. The study appears online in Nature Genetics...
Gut microbes influence colon cancer risk
11/06/2013
Scientists have known for some time that inflammation influences the development of colorectal cancer, but now, a new study suggests that gut microbes may also play a role...

Can cervical cancer be prevented with 1 dose of HPV vaccine?
11/06/2013
Women vaccinated with one dose of a human papillomavirus (HPV) vaccine had antibodies against the viruses that remained stable in their blood for four years, suggesting that a single dose of vaccine may be sufficient to generate long-term immune responses and protection against new HPV infections, and ultimately cervical cancer, according to a study published in Cancer Preventi...
