Salk researchers' findings on chromosome shortening suggest a potential target to arrest cancer cell growth A team of scientists at the Salk Institute for Biological Studies has identified why disruption of a vital pathway in cell cycle control leads to the proliferation of cancer cells. Their findings on telomeres, the stretches of DNA at the ends of chromosomes that protect our genetic code and make it possible for cells to divide, suggest a potential target for preventive measures...

Researchers from the Japanese Foundation for Cancer Research in Tokyo have discovered that forced elongation of telomeres (extensions on the end of chromosomes) promotes the differentiation of cancer cells, probably reducing malignancy, which is strongly associated with a loss of cell differentiation. They report their findings in a manuscript published online ahead of print, in the journal Molecular and Cellular Biology. "Cancer cells may maintain short telomeres to maintain their...

Omega-3 supplements like Omega XL shown to protect against age-related chromosome damage Hollywood, FL (PRWEB) June 24, 2013 An Ohio State University College of Medicine study published in the journal Brain, Behavior and Immunity shows omega-3 supplementation can reverse telomere shortening in cells – a key sign of aging. The double-blind study conducted using 106 overweight and sedentary adults showed that not only were telomeres lengthened in the omega-3 subjects, but oxidative stress...

RAP1 is a gene that also protects telomeres. This is the first time that a link has been found between these structures that shorten with ageing and obesity The discovery of an unexpected function for a gene that was associated to another process in the organism might be a solution in search of a problem, a clue to unsuspected connections. That is what has happened with RAP1, a gene that protects telomeres— the ends of chromosomes—after researchers from the Spanish National Cancer...

Genetic Thermometer Could Assess Overall Health
2013-05-23 05:50:51

Lee Rannals for redOrbit.com - Your Universe Online A new technique featured in the Journal of Visualized Experiments (JoVE) could lead to the development of a "genetic thermometer" that could assess a patient's health in relation to other individuals. The method developed by the laboratory of Dr. Gil Atzmon at New York´s Albert Einstein College of Medicine measures telomere length, which serve as the "caps" to chromosomes. Telomeres mark the ends of genetic material and ensure...

Researchers at UT Southwestern Medical Center have found that alternative splicing — a process that allows a single gene to code for multiple proteins — appears to be a new potential target for anti-telomerase cancer therapy. The enzyme telomerase is overexpressed in almost all cancer cells, and previous research efforts have failed to identify good telomerase inhibitors. The study by Dr. Woodring Wright and UT Southwestern colleagues in the April 4 issue of Cell Reports...

Less Children Mean Longer Life?

University of Gothenburg New research into ageing processes, based on modern genetic techniques, confirms theoretical expectations about the correlation between reproduction and lifespan. Studies of birds reveal that those that have offspring later in life and have fewer broods live longer. And the decisive factor is telomeres, shows research from The University of Gothenburg, Sweden. Telomeres are the protective caps at the end of chromosomes. The length of telomeres influences how...

DNA Strand Length Can Predict Heart Disease Death

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....


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
