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...

Children with Duchenne muscular dystrophy often die as young adults from heart and breathing complications. However, scientists have been puzzled for decades by the fact that laboratory mice bearing the same genetic mutation responsible for the disease in humans display only mild symptoms and no cardiac involvement. Now, researchers at the Stanford University School of Medicine have developed a mouse model that accurately mimics the course of the disease in humans. The study is the first...

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...

Many claims have been made for the health benefits of Omega-3 fatty acids in the diet. Dr. J G Moellendorf, DC, ND, LCP reviews recent research that demonstrates that it may also extend people´s lifespan. Sturgeon Bay, WI (PRWEB) June 20, 2013 Many health benefits have been noted from diets rich in Omega-3 fatty acids, according to Sturgeon Bay, Wisconsin Chiropractor and Naturopath Dr. J G Moellendorf, DC, ND, LCP. Recent research has been looking into the cellular mechanisms that...

Genetic Thermometer Could Assess Overall Health

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...

Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure. The creation of the first complete visual map of the telomerase enzyme, which is known to play a significant role in aging and most cancers, represents a breakthrough that could open up a host of new...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
