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

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...

Stowers team reconciles puzzling findings relating to centromere structure Scientists at the Stowers Institute of Medical Research have developed an innovative method to count the number of fluorescent molecules in a cluster and then applied the novel approach to settle a debate rampant among cell biologists–namely, how DNA twists into a unique chromosomal structure called the centromere. Knowing this helps explain how cells navigate the hazards of division and avoid the disastrous...

Connie K. Ho for redOrbit.com With food items like cheese and wine, it´s thought that a longer time of preparation will give it a better taste. This idea of age affecting quality was highlighted in a new study by Northwestern University scientists. A recent study by researchers at Northwestern University found that people whose fathers and grandfathers waited until they were older to have children tended to have a higher amount of resources for the body to repair cells and tissues....

Naphthalene is best known as the key ingredient in mothballs According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs. Researchers from the Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health,...
