(Ivanhoe Newswire) -- With 655,000 deaths worldwide per year from colorectal cancer, it is the fourth most common form of cancer in the United States.  Although it generally occurs in patients 60 and up, younger patients have been known to develop the cancer with no family history of it, and until now, researchers have been bemused as to why this occurs.  A recent study has uncovered a link involving telomeres and an increased risk for colorectal cancer in younger age groups that...

For the first time, researchers have found a link between long telomeres and an increased risk for colorectal cancer, according to research presented at the American Association for Cancer Research special conference on Colorectal Cancer: Biology to Therapy, held here Oct. 27-30, 2010. Telomeres are small strips of DNA that cover the ends of chromosomes "” they are similar to the plastic coverings on shoelace tips. They prevent chromosome tips from fraying during cell division. If the...

Accurate duplication of genetic material and the faithful segregation of chromosomes are critical for cell survival. The initiation of DNA replication is linked both to cell cycle progression and chromatin organization. In plants, animals and other "eukaryotes," the assembly of a multi-protein complex called pre-replicative complex (preRC) is the first step in the initiation of DNA replication. As the name implies, origin recognition complex (ORC) proteins bind to origins of DNA replication....

Like cats, human cells have a finite number of lives-once they divide a certain number of times (thankfully, more than nine) they change shape, slow their pace, and eventually stop dividing, a phenomenon called "cellular senescence". Biologists know that a cellular clock composed of structures at the chromosome end known as telomeres records how many "lives" a cell has expended. Up to now, investigators have not yet defined how the clock's ticking signals the approach of cellular oblivion. In...

(Ivanhoe Newswire) -- Among patients receiving immunosuppressive therapy for severe aplastic anemia, a condition in which the bone marrow is unable to produce blood cells, the length of telomeres (chromosome markers of biological aging) was clearly associated with a higher rate of relapse and lower overall survival. Severe aplastic anemia is characterized by life-threateningly low blood cell counts, but the condition can be treated by bone marrow transplant or immunosuppressive drugs. In...

New paper in Nature by Portuguese researchers provides light on paradox in cell biology world In the latest issue of the journal Nature, Miguel Godinho Ferreira, Principal Investigator at the Instituto Gulbenkian de Ciência (IGC) in Portugal, lead a team of researchers to shed light on a paradox that has puzzled biologists since the discovery of telomeres, the protective tips of chromosomes: while broken chromosome ends generated by DNA damage (such as radiation or...

RENO, Nev., Sept. 8 /PRNewswire/ -- Sierra Sciences, in collaboration with TA Sciences, Geron Corporation, PhysioAge, and the Spanish National Cancer Research Center (CNIO), has announced the first compound ever discovered that activates the enzyme telomerase in the human body - a critical prerequisite for technology that could arrest or reverse the aging process in humans. This compound is a natural product derived nutraceutical known as TA-65. These findings appear as a research article...

NEW YORK, Sept. 8 /PRNewswire/ -- A pioneering study published in the Rejuvenation Research Journal today shows that TA-65, a natural Telomerase Activator made and marketed by Telomerase Activation Sciences, Inc. ("T.A. Sciences"), reduces the percentage of short telomeres in immune cells and restores and remodels the aging human immune system to be more like that of a younger individual.

Can lead to serious disease in adulthood Children who experience trauma may enter a cycle of negative emotions "” anxiety and depression "” that could contribute to health problems later and precipitate an early death, a leading health psychologist said Saturday. "A child who experienced a death of a parent, witnessed severe marital problems between parents or was abused may be more vulnerable to stressful events later in life," said Janice Kiecolt-Glaser, PhD, of Ohio State...

SALT LAKE CITY, Aug. 4 /PRNewswire/ -- In a remarkable turn of events, arguably one of the strangest in the history of dietary supplements, men and women around the country are taking an herbal "belly fat" pill called Relacore® (from The Carter-Reed Company(TM)) to help reduce the signs of aging. And if consumer sales are any indication of a product's effectiveness, Relacore is nothing short of an "anti-aging" miracle. People are buying so much of this stuff that finding...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
