Brain Research: Call for help to killer cells improves cancer rejection ♦ Bringing anti-cancer technology to market ♦ Death-associated protein' promotes cancer growth

Call for help to killer cells improves cancer rejection Many tumors are infiltrated by cells of the innate immune system called eosinophils. Immunologists are now the first to show that eosinophils do, in fact, improve the body's defense against cancer. By releasing special agents, they attract killer T cells into cancerous tissue; the T cells then attack the cancer cells. This finding may help develop more effective cancer immunotherapies
Radiation experts unite to streamline cancer clinical trials Regulations on radiation exposure have been a critical bottleneck in starting up new cancer trials, but now radiation experts are pioneering a new streamlined system to reduce the time taken to set up clinical trials involving radiotherapy and other forms of ionising radiation, such as PET scans
Bringing anti-cancer technology to market New technology involves use of an antibody-based cancer therapy that down-regulates a plethora of pathways associated with resistant disease. The approach could advance treatment for patients with many forms of cancer, including breast, colorectal, lung, skin, and other epithelial-derived cancers.
Deaths attributable to cigarettes for 12 smoking-related cancers Researchers estimate that 48.5 percent of the nearly 346,000 deaths from 12 cancers among adults 35 and older in 2011 were attributable to cigarette smoking

Death-associated protein' promotes cancer growth in most aggressive breast cancers Although traditionally understood to induce death in cancer cells, researchers have discovered that the DAPK1 protein is actually essential for growth in breast and other cancers with mutations in the TP53 gene. This discovery indicates DAPK1 may be a promising new therapeutic target for many of the most aggressive cancers.
