Cancer Research: Engineers develop 'killer cells' to destroy cancer in lymph nodes ♦ Kidney failure and its treatment may impact cancer risk ♦ Drug could limit spread of deadly brain tumors

Tracing activity of cancer-fighting tomato component Years of research have demonstrated that lycopene, the bioactive red pigment found in tomatoes, reduces growth of prostate tumors in a variety of animal models. When consumed, lycopene undergoes a change in its chemical structure that potentially influences health,

Drug could limit spread of deadly brain tumors In a significant breakthrough, researchers have identified a drug, propentofylline or PPF, that could help treat patients with deadly brain cancer. They report that PPF works to limit the spread of glioblastoma multiforme, or GBM -- the most common primary tumor of the brain and central nervous system -- by targeting a protein called TROY.

Engineers develop 'killer cells' to destroy cancer in lymph nodes Biomedical engineers have developed specialized white blood cells -- dubbed 'super natural killer cells' -- that seek out cancer cells in lymph nodes with only one purpose: destroy them. This breakthrough halts the onset of metastasis.

Kidney failure and its treatment may impact cancer risk Risk of kidney and thyroid cancers was especially high when kidney failure patients were on dialysis, researchers have discovered. Conversely, risk of non-Hodgkin lymphoma, melanoma, lung cancer, and certain skin cancers was highest following kidney transplantation, likely due to immunosuppressant medications. Kidney failure is on the rise and currently afflicts an estimated 2 million people worldwide.
