The Mount Sinai Hospital / Mount Sinai School of Medicine A protein may be the key to maintaining the health of aging blood stem cells, according to work by researchers at the Icahn School of Medicine at Mount Sinai recently published online in Stem Cell Reports. Human adults keep stem cell pools on hand in key tissues, including the blood. These stem cells can become replacement cells for those lost to wear and tear. But as the blood stem cells age, their ability to regenerate blood...

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Washington University School of Medicine in St. Louis have reportedly discovered the mechanism through which a specific type of protein can bring about a “significant delay” in the aging process. Writing in the September 3 issue of the journal Cell Metabolism, the study authors explain how one sirtuin protein (a class of proteins that have been linked to cellular processes like aging, transcription,...

A study finds a possible link between a drug alternative that could slow age-associated impairments in the brain with restricting caloric intake. Prescopodene Nutritionals feels they can help reduce food consumption to extend brain functionality. Sydney, Australia (PRWEB) June 21, 2013 In an article on Science Daily's website, there has been evidence showing that restricting caloric intake can activate an enzyme called Sirtuin 1, or SIRT1, which may offer protection against...

Animal study points to role of protein in anti-aging benefits of calorie restriction Activating an enzyme known to play a role in the anti-aging benefits of calorie restriction delays the loss of brain cells and preserves cognitive function in mice, according to a study published in the May 22 issue of The Journal of Neuroscience. The findings could one day guide researchers to discover drug alternatives that slow the progress of age-associated impairments in the brain. Previous studies...

Dr. Simon Ourian of Epione Beverly Hills says the new research data is very exciting and looks forward to seeing practical skin care applications. Los Angeles, CA (PRWEB) April 05, 2013 According to a March 11, 2013 CBS News article, researchers from Harvard Medical School have confirmed that the compound resveratrol, which is found in red wine, provides cosmetic and...

Human Genetic Mutation Discovery Could Lead To New Treatments For Type 1 Diabetes
2013-03-05 12:58:58

Cell Press In type 1 diabetes, the immune system destroys insulin-producing cells in the pancreas, but the precise cause has not been clear. A study published by Cell Press on March 5th in Cell Metabolism reveals that a single mutation in the "longevity gene" SIRT1 can cause type 1 diabetes in humans. The findings unearth the role this gene plays in human autoimmunity and disease and also offer new avenues for treating a range of autoimmune disorders. "We describe one of the first...

Vibration-induced white finger disease (VWF) is caused by continued use of vibrating hand held machinery (high frequency vibration >50 Hz), and affects tens of thousands of people. New research published in BioMed Central's open access journal Clinical Epigenetics finds that people with a genetic polymorphism (A2191G) in sirtuin1 (SIRT1), a protein involved in the regulation of endothelial NOS (eNOS), are more likely to suffer from vibration-induced white finger disease. VWF (also known...

Milk Ingredient Protects Against Obesity

Connie K. Ho for redOrbit.com Milk ads have long proclaimed that milk does the body good. Now, there may be research that backs this idea of milk as having particular attributes to boost a healthy body. Researchers found that a natural ingredient in milk can help protect against obesity, even when mice consume foods that are high in fat. The findings, published in the June issue of Cell Metabolism, believe that the milk ingredient is similar to a new type of vitamin. The discovery of NR...

New research reinforces the claim that resveratrol–a compound found in plants and food groups, notably red wine–prolongs lifespan and health-span by boosting the activity of mitochondria, the cell's energy supplier. "The results were surprisingly clear," said David Sinclair, a professor of genetics at Harvard Medical School and the study's senior author. "Without the mitochondria-boosting gene SIRT1, resveratrol does not work." Over the last decade, Sinclair and colleagues...

(Ivanhoe Newswire) — Treatment that increases brain levels of a crucial regulatory enzyme may slow the loss of brain cells that characterize Huntington´s disease (HD) and other neurodegenerative disorders, according to this study. Increased expression of Sirt1, one of a family of enzymes called sirtuins, in the brain of a mouse model of HD protected against neurodegeneration. They also identified a potential mechanism for this protective effect. "Diseases such as Huntington's,...
