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...

A study shows for the first time that the three most common chromosome changes seen in chronic lymphocytic leukemia disrupt a molecular network that includes several important genes and strongly influences the outcome of the disease. The research was led by investigators at the Ohio State University Comprehensive Cancer Center "“ Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC "“ James) and at University of Texas M.D. Anderson Cancer Center,...

JAMA paper provides molecular framework for effect of chromosome deletion in CLL The interplay between a major tumor-suppressing gene, a truncated chromosome and two sets of microRNAs provides a molecular basis for explaining the less aggressive form of chronic lymphocytic leukemia, an international team of researchers reports today in the Jan. 4 edition of the Journal of the American Medical Association. "Our findings could reveal new mechanisms of resistance to chemotherapy among leukemia...
