New year, new vitamin C discovery: It ‘cures’ mice with accelerated aging disease
New research in the FASEB Journal reports vitamin C reverses abnormalities caused by Werner syndrome gene, including cancer, obesity, diabetes, heart failure and high cholesterol
A new research discovery published in the January 2010 print issue of the FASEB Journal (http://www.fasebj.org) suggests that treatments for disorders that cause accelerated aging, particularly Werner’s syndrome, might come straight from the family medicine chest. In the research report, a team of Canadian scientists show that vitamin C stops and even reverses accelerated aging in a mouse model of Werner’s syndrome, but the discovery may also be applicable to other progeroid syndromes. People with Werner’s syndrome begin to show signs of accelerated aging in their 20s and develop age-related diseases and generally die before the age of 50.
“Our study clearly indicates that a healthy organism or individuals with no health problems do not require a large amount of vitamin C in order to increase their lifespan, especially if they have a balanced diet and they exercise,” said Michel Lebel, Ph.D., co-author of the study from the Centre de Recherche en Cancerologie in Quebec, Canada. “An organism or individual with a mutation in the WRN gene or any gene affected by the WRN protein, and thus predisposes them to several age-related diseases, may benefit from a diet with the appropriate amount of vitamin C.”
Scientists treated both normal mice and mice with a mutation in the gene responsible for Werner’s syndrome (WRN gene) with vitamin C in drinking water. Before treatment, the mice with a mutated WRN gene were fat, diabetic, and developing heart disease and cancer. After treatment, the mutant mice were as healthy as the normal mice and lived a normal lifespan. Vitamin C also improved how the mice stored and burned fat, decreased tissue inflammation and decreased oxidative stress in the WRN mice. The healthy mice did not appear to benefit from vitamin C.
“Vitamin C has become one of the most misunderstood substances in our medicine cabinets and food,” said Gerald Weissmann, M.D., Editor-in-Chief of the FASEB Journal. “This study and others like it help explain how and why this chemical can help to defend some, but certainly not all, people from premature senescence.”

The FASEB Journal (http://www.fasebj.org) is published by the Federation of the American Societies for Experimental Biology (FASEB). The journal has been recognized by the Special Libraries Association as one of the top 100 most influential biomedical journals of the past century and is the most cited biology journal worldwide according to the Institute for Scientific Information. FASEB is composed of 23 societies with more than 90,000 members, making it the largest coalition of biomedical research associations in the United States. FASEB enhances the ability of biomedical and life scientists to improve-through their research-the health, well-being and productivity of all people. Its mission is to advance health and welfare by promoting progress and education in biological and biomedical sciences through service to our member societies and collaborative advocacy.
