New research being presented this week is giving scientists new insight into why a restricted diet can lead to a longer lifespan and reduced incidence of age-related diseases for a wide variety of animals. Scientists have known for some time that a restricted diet can extend the lifespan of certain animals but this work shows how it affects ageing mechanisms "“ and significantly has also shown that the effects occur even if the restricted diet is adopted later in life. The work could...

A new study suggests that shorter length of leukocyte telomeres "“ chromosome markers of biological aging "“ are associated with an increased risk of cancer and death from cancer, according to a study in the July 7 issue of JAMA. A leukocyte is a type of blood cell. Telomeres are a structure at the end of a chromosome involved in the replication and stability of the chromosome. Genetic factors and environmental stressors can shorten the length of the telomere, and telomere length...

Scientists from the University of Warwick and University Hospitals Coventry and Warwickshire NHS Trust, are the first to directly measure a specific region of DNA in human embryos. The length of this region could be a quality marker for embryonic development. Researchers at the University of Warwick's Warwick Medical School and University Hospital, Coventry, have measured telomeres, regions of repetitive DNA at the ends of a chromosome which protect it from deterioration. Telomeres shorten...

Study into telomere length may improve understanding of the development of disease A new study at the University of Leicester is examining a sequence of DNA- known as telomeres - that varies in length between individual. This follows evidence that these structures shrink in length over an individual's lifetime and that this may contribute to several diseases including those commonly associated with ageing and, perhaps most importantly, the development of cancer. Now the study is trying to...

A gene shown to play a role in the aging process appears to play a role in the regulation of the differentiation of embryonic stem cells, according to researchers from the Center for Stem Cell Biology and Regenerative Medicine and the Department of Medicine at Thomas Jefferson University. In the study, published online in the journal Aging Cell, the researchers identified a protein interaction that controls the silencing of Oct4, a key transcription factor that is critical to ensuring that...

Exercise can buffer the effects of stress-induced cell aging, according to new research from UCSF that revealed actual benefits of physical activity at the cellular level. The scientists learned that vigorous physical activity as brief as 42 minutes over a 3-day period, similar to federally recommended levels, can protect individuals from the effects of stress by reducing its impact on telomere length. Telomeres (pronounced TEEL-oh-meres) are tiny pieces of DNA that promote genetic stability...

WASHINGTON, D.C. -- Researchers have detected a link between alcohol consumption, cancer and aging that starts at the cellular level with telomere shortening. Results of this cross-sectional study were presented at the American Association for Cancer Research 101st Annual Meeting 2010, held here, April 17-21, at the Walter E. Washington Convention Center. Telomeres are found at the region of DNA sequences at the end of a chromosome, and are important for the genetic stability of cells....

DENVER, April 8 /PRNewswire/ -- Improving nerve regeneration after corneal surgery, preventing psychotic disorders in those at high risk for them and reducing cellular aging are three emerging benefits of the omega-3 fatty acids found in seafood, according to milestone research described in the April 2010 PUFA Newsletter and Fats of Life online publications for health professionals and consumers, respectively. One study showed that after corneal surgery, such as LASIK, treating eyes with...

Children who suffer physical or emotional abuse could be faced with accelerated cellular aging as adults, according to new research published by Elsevier in Biological Psychiatry. It's an easy fact to forget - the aging process begins at birth. Despite this, cellular aging remains somewhat of a mystery, although there is growing evidence that over time, the DNA within cells begins to show signs of aging. One of these signs is the shortening of telomeres, which are DNA "caps" at the end of...
