CAMBRIDGE, UNITED KINGDOM - DECEMBER 09: A Scientist looks at cells through a fluorescent microscope at the laboratories at Cancer Research UK Cambridge Institute on December 9, 2014 in Cambridge, England. Cancer Research UK is the world's leading cancer charity dedicated to saving lives through research. Its vision is to bring forward the day when all cancers are cured. They have saved millions of lives by discovering new ways to prevent, diagnose and treat cancer, and as such the survival rate in the UK has doubled in the last 40 years. Cancer Research UK funds over 4,000 scientists, doctors and nurses across the UK, more than 33,000 patients who join clinical trials each year and a further 40,000 volunteers that give their time to support the work.

There is new hope for those suffering from Alzheimer's. Scientists have found that a previously approved drug originally developed to treat cancer could potentially be used to treat Alzheimer's.

The compound, saracatinib, restores memory loss and reverses brain problems in mice with Alzheimer's disease-like symptoms. By targeting beta amyloid deposits - which is a precursor of Alzheimer's disease - and reducing their toxic effect, saracatinib restores connections between brain cells.

"With this treatment, cells under bombardment by beta amyloid plaques show restored synaptic connections and reduced inflammation, and the animal's memory, which was lost during the course of the disease, comes back," said Stephen M. Strittmatter, the Vincent Coates Professor of Neurology and senior author of the study, in a report by Sciencedaily.com.

The study was carried out in collaboration with the National Center for Translational Services, which is part of the National Institutes of Health. According to a report by Washingtonpost.com, it is designed to transform research into practical results as quickly as possible.

The center is currently focused on finding off-purpose uses of approved drugs. In an effort to systematize serendipity, the facility is equipped with robotic arms and "tissue chips" - which combine microchips with living stem cell cultures - to run as many as three million tests a week. In this way, other purposes can be found for already existent drugs, such as the case with Viagra, which was originally designed as a blood pressure medication and is now used to treat erectile dysfunction.

Other off-purpose drugs currently under testing to treat Alzheimer's include acamprosate calcium, which is prescribed to reduce cravings and alleviate withdrawal symptoms in alcoholics, and baclofen, a medication used to treat multiple sclerosis.

In the case of saracatinib, mice were genetically modified to produce Alzheimer's-like symptoms, including the buildup of beta-amyloid in brain tissue and memory loss. After four weeks of the treatment, the mice showed a reversal in their memory loss as well as restoration of synapse loss.

Alzheimer's disease is the most common form of dementia and currently afflicts nearly 5 million Americans. The illness causes clumps of amyloid beta protein to build up in the brain, and these protein clusters damage and eventually kill brain cells.

Alzheimer's disease also leads to loss of synapses, which are the spaces between neurons through which the cells communicate with each other and form memories. Current Alzheimer's drug therapies only ease symptoms without actually stopping the disease from progressing.
