NYU Langone Medical Center researchers find micro RNA plays a key role in melanoma metastasis
NEW YORK CITY (February 5, 2009)Scientists have long wondered how melanoma cells travel from primary tumors on the surface of the skin to the brain, liver and lungs, where they become more aggressive, resistant to therapy, and deadly. Now, scientists from NYU Langone Medical Center have identifi...
Newly identified gene powerful predictor of colon cancer metastasis
Cancer Researchers at the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch and the Charit Universitts Medizin Berlin (Germany) have identified a gene which enables them to predict for the first time with high probability if colon cancer is going to metastasize. Assistant Professor Dr. ...
It is important to demonstrate the influence of the microenvironment in the process of metastasis

A gene for metastasis
Colorectal cancer is one of the most prevalent cancers in the Western world. The tumor starts off as a polyp but then turns into an invasive and violent cancer, which often spreads to the liver. In an article recently published in the journal Cancer Research, Prof. Avri Ben-Zeev and Dr. Nancy Gave...
Inflammation may play role in metastasis of prostate cancer
Many would assume that "mounting an immune response" or "having your body fight the cancer" is a good thing. Now, research at the University of California, San Diego (UCSD) School of Medicine strongly suggests that inflammation associated with the progression of tumors actually plays a key role in...
'Trojan Horse' agent halts bone metastasis in mice
A novel vascular targeting agent completely prevented the development of bone tumors in 50 percent of the mice tested in a preclinical study, providing early evidence that it could treat, or thwart, growth of tumors in bone, a common destination for a number of cancers when they start to spread.
Two-faced protein can stop metastasis or promote it, researchers say
