Cancer Research: A new virus in liver cancer ♦ Tumour suppressor genes curb growth in neighboring cells ♦ Researchers thwart cancer cells by triggering 'virus alert'

A new virus in liver cancer More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened by hepatitis B or C virus. Researchers have just identified the role of a new virus, hitherto unsuspected, in the occurrence of a rare type of liver cancer.
New strategy improves detection of genetic mutations in hereditary colorectal cancer Enhanced accuracy and reduced turnaround time of testing can provide vital information for patients suspected of having lynch syndrome and their family members, according to a new report.
New synthetic tumor environments make cancer research more realistic Tumors are notoriously difficult to study in their natural habitat -- body tissues -- but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior. Researchers have now developed a new technique to create a cell habitat of hydrogels which can realistically and quickly recreate microenvironments found across biology.
Tumor suppressor genes curb growth in neighboring cells Researchers have unraveled a role for tumor suppressor genes in restricting the growth of neighboring cell populations. The study might have implications for understanding the early events of tumorigenesis and the selection of the tumour-initiating cells.
Researchers thwart cancer cells by triggering 'virus alert' Working with human cancer cell lines and mice, researchers have found a way to trigger a type of immune system 'virus alert' that may one day boost cancer patients' response to immunotherapy drugs. An increasingly promising focus of cancer research, the drugs are designed to disarm cancer cells' ability to avoid detection and destruction by the immune system.
