Salmonella 'can kill cancer': How bacteria that cause food poisoning could be used to attack tumour cells
A genetically-altered form of salmonella is being developed to combat cancer It would kill off the tumour cells while leaving the healthy cells alone The new strain would also help the body’s immune system target tumours The bacteria that cause food poisoning could be used to kill cancer, medical experts said yesterday. A genetically-altered form of...

Role of rogue protein PAK4 confirmed in pancreatic cancer cells
A new study that confirms the role of a protein called PAK4 in the movement and growth of pancreatic cancer cells could help researchers find new ways to tackle the disease. The work, funded by national charity Pancreatic Cancer Research Fund, uncovers new evidence that PAK4 plays a key role in enabling cancer cells to...

How cancers trick the immune system into helping rather than harming them
Scientists at Trinity College Dublin have discovered how certain cancers hijack the immune system for their benefit — tricking it into helping rather than harming them. While most of us are aware that our immune system protects us from infection, we may be less aware of the key role that cells of the immune system also...

Stem cells collected from fat may have use in anti-aging treatments
Adult stem cells collected directly from human fat are more stable than other cells — such as fibroblasts from the skin — and have the potential for use in anti-aging treatments, according to researchers from the Perelman School of Medicine at the University of Pennsylvania. They made the discovery after developing a new model to...
