Cancer Research: Compound in magnolia may combat cancer ♦ Earlier, easier detection of colorectal cancer ♦ Cancer drug makes fruit flies live longer

Compound in magnolia may combat head and neck cancers As one of the compounds in magnolia extract, honokiol has been used for centuries in traditional Chinese and Japanese medicine to treat anxiety and other conditions. More recently, scientists have been revealing its cancer-fighting properties.
New approach holds promise for earlier, easier detection of colorectal cancer A new, sensitive electrochemical technique capable of detecting colorectal cancer in tissue samples has been developed by chemists -- a method that could one day be used in clinical settings for the early diagnosis of colorectal cancer.
Cancer drug makes fruit flies live longer Adult fruit flies given a cancer drug live 12 percent longer than average, according to a study researching healthy aging. The drug targets a specific cellular process that occurs in animals, including humans, delaying the onset of age-related deaths by slowing the aging process.
New drug squashes cancer's last-ditch efforts to survive As a tumor grows, its cancerous cells ramp up an energy-harvesting process to support its hasty development. This process, called autophagy, is normally used by a cell to recycle damaged organelles and proteins, but is also co-opted by cancer cells to meet their increased energy and metabolic demands. A compound that stops this cellular recycling process has now been developed by scientists.
New class of compounds shrinks pancreatic cancer tumors, prevents regrowth A chemical compound that has reduced the growth of pancreatic cancer tumors by 80 percent in treated mice has been developed by researchers. The compound, called MM41, was designed to block faulty genes. It appears to do this by targeting little knots in their DNA, called quadruplexes, which are very different from normal DNA and which are especially found in faulty genes.
