Telomere Length Predicts Longevity
2012-11-20 13:04:15

Brett Smith for redOrbit.com - Your Universe Online New research from the University of East Anglia in the UK has found a correlation among biological age, longevity and an individual´s DNA. By studying a wild population of Seychelles Warblers on a small island, the geneticists were able to demonstrate how the end-caps of chromosomes, known as telomeres, shorten due to age and stress, and can be an indication of life expectancy. "Over time these telomeres get broken down and...

A team of researchers at Kaiser Permanente and the University of California, San Francisco (UCSF) has identified a significant relationship between mortality and the length of telomeres, the stretches of DNA that protect the ends of chromosomes, according to a presentation on Nov. 8 at the American Society of Human Genetics 2012 meeting in San Francisco. While a reduction in telomere length is regarded as a biomarker of aging, scientists have not yet determined whether it plays a direct...

BOCA RATON, Fla., Oct. 1, 2012 /PRNewswire/ -- Noel Thomas, Founder of TA Sciences, a New York, NY-based organization dedicated to lengthening the human lifespan, and Dr. Ed Park, an expert in the field of telomerase activators, will appear on The SUZANNE Show this week to discuss an enzyme that may be able to slow the aging process. Their appearance, which is one in a series devoted to natural life extension, airs Wednesday, October 3, at 7 a.m. (ET/PT) on Lifetime Television. According to...

American Heart Association meeting report: BCVS-12 Abstract 62 Damaged and aged heart tissue of older heart failure patients was rejuvenated by stem cells modified by scientists, according to research presented at the American Heart Association's Basic Cardiovascular Sciences 2012 Scientific Sessions. The study is simultaneously published in the Journal of the American College of Cardiology. The research could one day lead to new treatments for heart failure patients, researchers said....

UCLA biochemists have mapped the structure of a key protein—RNA complex that is required for the assembly of telomerase, an enzyme important in both cancer and aging. The researchers found that a region at the end of the p65 protein that includes a flexible tail is responsible for bending telomerase's RNA backbone in order to create a scaffold for the assembly of other protein building blocks. Understanding this protein, which is found in a type of single-celled organism that lives...

Preclinical study links aging and cancer, with lethal host metabolism in the tumor microenvironment It has long been known that cancer is a disease of aging, but a molecular link between the two has remained elusive. Now, researchers at the Kimmel Cancer Center at Jefferson (KCC) have shown that senescence (aging cells which lose their ability to divide) and autophagy (self-eating or self-cannibalism) in the surrounding normal cells of a tumor are essentially two sides of the same coin,...

Researchers at NYU School of Medicine have, for the first time, identified a single gene that simultaneously controls inflammation, accelerated aging and cancer. "This was certainly an unexpected finding," said principal investigator Robert J. Schneider, PhD, the Albert Sabin Professor of Molecular Pathogenesis, associate director for translational research and co-director of the Breast Cancer Program at NYU Langone Medical Center. "It is rather uncommon for one gene to have two very...

Mouse lifespan extended up to 24 percent with a single treatment A number of studies have shown that it is possible to lengthen the average life of individuals of many species, including mammals, by acting on specific genes. To date, however, this has meant altering the animals' genes permanently from the embryonic stage — an approach impracticable in humans. Researchers at the Spanish National Cancer Research Centre (CNIO), led by its director María Blasco, have proved...

(Ivanhoe Newswire) -- In today's society, kids already act and look older than they are. Recent research has proved that the DNA of 10-year-olds who have experienced violence at a young age are found to show wear and tear normally associated with aging. "This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress," Idan Shalev, a post-doctoral researcher in psychology and neuroscience at the...

Children Age Faster When Exposed To Violence And Bullying
2012-04-25 10:07:00

Researchers have found that violence in the lives of children can cause changes in their DNA equivalent to seven to 10 years of premature aging. Scientists measured this cellular aging by studying the ends of children´s chromosomes, called telomeres. Telomeres are DNA sequences that act like the plastic tips on shoelaces, which prevent the DNA in chromosomes from unraveling. Each time a cell divides, the telomeres become shorter until a cell dies when it can´t divide anymore,...
