DNA Strand Length Can Predict Heart Disease Death
2013-03-11 20:36:52

Lee Rannals for redOrbit.com — Your Univere Online Researchers studying more than 3,500 patients with heart disease say the length of DNA strands can help predict life expectancy. Scientists at the Intermountain Heart Institute at Intermountain Medical Center in Salt Lake City presented a new study March 9 at the American College of Cardiology's Annual Scientific Session in San Francisco, claiming they were able to predict survival rates among patients with heart disease. The...

Among healthy adults who were administered a cold virus, those with shorter telomere length (a structure at the end of a chromosome) in certain cells were more likely to develop experimentally-induced upper respiratory infection than participants with longer telomeres, according to results of preliminary research published in the February 20 issue of JAMA. Telomeres shorten with each cell division and function as protective caps to prevent erosion of genomic DNA during cell division....

Biological Markers In Chromosomes Predict The Common Cold

[Watch Video: Biological Marker Predicts Susceptibility To Common Cold] Lawrence LeBlond for redOrbit.com - Your Universe Online While predicting future events has been met with much skepticism, many scientists make it their life work to predict what will happen in the future. Such predictions include what regional weather will be like, how much warmer the planet will be, and even when the Sun will die. But predictive science is not limited to just forecasting the weather or...

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome replication and may offer insights into the factors behind the production of abnormal numbers of chromosomes. Their findings appear in the latest issue of the journal the Proceedings of the National Academy of Sciences. The researchers focused on the organization and...

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...

Wandering Mind Linked To Telomere Length
2012-11-18 07:59:31

redOrbit Staff & Wire Reports - Your Universe Online While previous research has suggested that individuals with wandering minds could be exhibiting signs of unhappiness, a new study shows that the inability to focus on a task at hand could be linked to aging. In the new study, scientists from the University of California, San Francisco (UCSF) discovered that telomere length, a biological measure of aging at both the cellular and overall physiological level, played a role on whether...

Down Syndrome Researchers Remove Extra Chromosome
2012-11-12 14:52:09

Brett Smith for redOrbit.com - Your Universe Online Geneticists from the University of Washington won a key victory in the battle against genetic diseases by successfully removing the extra chromosome 21 from cells derived from a person with Down syndrome, according to the team´s report in the journal Cell Stem Cell. Down syndrome, also known as trisomy 21, is caused by an extra copy of chromosome 21. In addition to the tell-tale facial features such as an abnormally small chin 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...

The combination of shortened telomeres, a biological marker of aging associated with cancer development, and elevated depression significantly impacted bladder cancer mortality, according to data presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held here Oct. 16-19, 2012. "We found that patients with bladder cancer with shorter telomeres and high levels of depression symptoms have a threefold increased risk for mortality," said Meng...
