A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin. In the comparatively simple organism fission yeast, a cellular phenomenon known as RNA interference (RNAi) plays an essential role in assembling heterochromatin, which keeps the compressed DNA in an inactive or "silent" state. Central to this process is a large protein complex that physically anchors various molecules involved in heterochromatin assembly to the...

Scientists of the German Cancer Research Center have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes. The ends of the chromosomes, the telomeres, are repetitive DNA sequences that shorten every time a cell divides during the process of duplicating its genome. Once the telomeres become very short the cell stops dividing. Thus, telomeres work like a cellular clock that keeps an eye on the number of cell divisions. And once the...

Turning Back The Clock On Adult Stem Cell Aging

  Researchers have shown they can reverse the aging process for human adult stem cells, which are responsible for helping old or damaged tissues regenerate. The findings could lead to medical treatments that may repair a host of ailments that occur because of tissue damage as people age. A research group led by the Buck Institute for Research on Aging and the Georgia Institute of Technology conducted the study in cell culture, which appears in the September 1, 2011 edition of the...

Johns Hopkins researchers say data show aging alone, not hormonal impact of menopause, explains increasing number of deaths as women age Contradicting the long-held medical belief that the risk of cardiovascular death for women spikes sharply after menopause, new research from Johns Hopkins suggests instead that heart disease mortality rates in women progress at a constant rate as they age. The findings, published in BMJ, the British medical journal, could have implications for how...

Study published in The American Journal of Pathology The first report of the presence of alternative lengthening of telomeres (ALT) in cancers arising from the bladder, cervix, endometrium, esophagus, gallbladder, liver, and lung was published today in The American Journal of Pathology. The presence of ALT in carcinomas can be used as a diagnostic marker and has implications for the development of anti-cancer drug therapies. Telomeres are nucleoprotein complexes located at the ends of...

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered a new mechanism controlling ageing in white blood cells. The research, published in the September issue of the Journal of Immunology, opens up the possibility of temporarily reversing the effects of ageing on immunity and could, in the future, allow for the short-term boosting of the immune systems of older people. Weakened immunity is a serious issue for older people. Because our immune...

Research points to critical role of maternal health and well-being during pregnancy Young adults whose mothers experienced psychological trauma during their pregnancies show signs of accelerated aging, a UC Irvine-led study found. The researchers discovered that this prenatal exposure to stress affected the development of chromosome regions that control cell aging processes. The study results, which appear online this week in the Proceedings of the National Academy of Sciences, point to the...
