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 ...

Call of the riled: Stress signal in cancer cells triggers similar response in other cells, aiding tumor growth
Researchers at the University of California, San Diego School of Medicine say a "stress response" mechanism used by normal cells to cope with harsh or demanding conditions is exploited by cancer cells, which ...

Viral replicase points to potential cancer therapy
Alpha viruses, such as Sindbis virus, carry their genetic information on a single strand of RNA. On infection they use a protein, replicase, to produce double stranded RNA (dsRNA) which is used as genetic material to make ...

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 ...

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 ...

Brain tumor growth linked to lowered expression of hundreds of immune function genes
A new study links progression of a lethal type of brain tumor with reduced expression of more than 600 immune system genes, suggesting how complex the immune response is to the cancer and the resulting difficulty in targeting ...

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. ...

Inflammation 'on switch' also serves as 'off switch'
In a surprising finding, researchers at North Carolina State University have discovered the critical importance of a protein previously believed to be a redundant "on switch" for certain immune-system responses.
