In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists at the Salk Institute for Biological Studies have uncovered an important clue to one of the mechanisms underlying cancer cell immortality.Their findings, published in the April 22, 2011 issue of Molecular Cell, reveal an unanticipated structure at chromosome ends, which could be a key...

A study of DNA rearrangements in roundworm chromosomes may offer new insight into large-scale genome duplications that occur in developing tumors. A report of the research led by University of North Carolina at Chapel Hill School of Medicine scientists was published in the April 22 online edition of the journal Science. The study focused on telomeres, a region of repetitive DNA sequence that protects the ends of chromosomes from deterioration or from fusing with other chromosomes. In many...

UCSF scientists are reporting several studies showing that psychological stress leads to shorter telomeres "“ the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health. The findings also suggest that exercise may prevent this damage. The team focused on three groups: post-menopausal women who were the primary caregivers for a family member with dementia; young to middle-aged adults with post-traumatic stress disorder; and healthy, non-smoking women...

UT MD Anderson scientists also link the same SNP to longer telomeres A common genetic variation links to both bladder cancer risk and to the length of protective caps found on the ends of chromosomes, scientists at The University of Texas MD Anderson Cancer Center reported today at the AACR 102nd Annual Meeting. These endings or tips, called telomeres, guard against chromosomal damage and genomic instability that can lead to cancer and other diseases. "We found a single point of variation in...

Results of a study presented at the AACR 102nd Annual Meeting 2011, held here April 2-6, lend credence to the idea that improving quality of life affects stress-related biological markers and possibly the health of people with cancer. Researchers know that telomeres shorten and deteriorate with aging, but they are learning that stress also affects telomere length. "We are trying to understand the interconnections between the mind and the body; that is, how does the diagnosis and treatment of...

Using new genetic information, scientists have linked a commonly found human genetic variant with both longer telomeres and reduced risk of bladder cancer, according to findings presented at the AACR 102nd Annual Meeting 2011, held April 2-6, and simultaneously published in Cancer Prevention Research, a journal of the American Association for Cancer Research. Jian Gu, Ph.D., assistant professor of epidemiology at The University of Texas MD Anderson Cancer Center, said the single-nucleotide...

New role for short telomeres New evidence has emerged from studies in mice that short telomeres or "caps" at the ends of chromosomes may predispose people to age-related diabetes, according to Johns Hopkins scientists. Telomeres are repetitive sequences of DNA that protect the ends of chromosomes, and they normally shorten with age, much like the caps that protect the end of shoelaces. As telomeres shorten, cells lose the ability to divide normally and eventually die. Telomere shortening has...

Researchers from Cyprus report that a simple blood test can predict whether a baby is likely to have Down Syndrome. DNA differences between the mother and the fetus can be shown to accurately predict which fetuses are at risk of developing the syndrome, Reuters reports. "We believe we can modify this test and make it much easier and simple... (and then) we can have something ready to be introduced into the clinic," Philippos Patsalis, medical director of the Cyprus Institute of Neurology and...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
