A turn-off for cancer: Scientists discover an ancient 'switch' in plants that could halt cancer metastasis
Although plants and animals are very different organisms, they share a surprising number of biological mechanisms. A plant biologist at Tel Aviv University says that one of these mechanisms may be the answer ...

Researchers identify potential molecular target to prevent growth of cancer cells
Researchers have shown for the first time that the protein fortilin promotes growth of cancer cells by binding to and rendering inert protein p53, a known tumor suppressor. This finding by researchers at the University of ...

A crystal ball for brain cancer? New method predicts which brain tumors will respond to drug
UCLA researchers have uncovered a new way to scan brain tumors and predict which ones will be shrunk by the drug Avastin -- before the patient ever starts treatment. By linking high water movement in tumors ...

Nanoparticle Developed To Boost Anti-Cancer Immunotherapy
(PhysOrg.com) -- One of the hallmarks of cancer is that tumors are able to suppress the immune system, preventing the body's own defense system from eliminating the disease, particularly as tumors spread through the body. ...

Using a molecular switch to turn on cancer vaccines
The immune system is capable of recognizing tumor growth, and naturally mounts an anti-cancer defense. Dendritic cells (DCs) can take up tumor-derived molecules (antigens) and present them to T cells, and those "primed" T ...
