Telomeres - the indicators of aging - are highly susceptible to stress and depression

Stress has numerous detrimental effects on the human body. Many of these effects are acutely felt by the sufferer, but many more go 'unseen', one of which is shortening of telomere length.

Genomic instability allows malignant cells to acquire more deadly characteristics

Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those aps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

Direct link between short telomere length, heart attack and early death

Every cell in the body has chromosomes with so-called telomeres, which are shortened over time and also through lifestyle choices such as smoking and obesity. Researchers have long speculated that the shortening of telomeres increases the risk of heart attack and early death. Now a large-scale population study in Denmark involving nearly 20,000 people shows that there is in fact a direct link, and has also given physicians a future way to test the actual cellular health of a person.

DNA may be used to predict lifespan: Study

Researchers may soon be able to predict how long a person will live based on their genetics. This could result from the discovery by a University of Glasgow team in Scotland showing that telomere length on the ends of DNA in their genes in early-life predicts life spans.

Blocking telomerase increases cancer cells' sensitivity to radiation treatment

Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells' sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research.

People with recurrent depression, chronic stress have shorter telomeres in WBCs

People with recurrent depressions or those exposed to chronic stress exhibits shorter telomeres in white blood cells. This is shown by a research team at Umeå University in a coming issue of Biological Psychiatry.

Scientists discover alternative mechanism for extension of telomeres

Scientists of the German Cancer Research Center have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes.

Study: No big shift toward higher fatal heart attack rates after menopause in women

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.

First report of alternative lengthening of telomeres in human cancer subtypes

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.

Amniotic fluid-derived stem cells show promise against lung disease

Two papers published in the current issue of Cell Transplantation, highlight the rich source of stem cells in human amniotic fluid that can be isolated and transplanted for therapeutic purposes.

Researchers discover new mechanism that controls ageing in WBCs

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered a new mechanism controlling ageing in white blood cells.

UCSF, Kaiser Permanente achieve first major milestone in genomics project

One of the nation's largest and most diverse genomics projects has reached its first major milestone in just 15 months. Scientists have genotyped the DNA and analyzed the length of chromosome tips in more than 100,000 Kaiser Permanente members who agreed to be part of the research.

Short telomeres may increase risk of emphysema

Telomeres, the body's own cellular clocks, may be a crucial factor underlying the development of emphysema, according to research from Johns Hopkins University.

PDF announces $1M for 11 novel Parkinson's research projects

The Parkinson's Disease Foundation (PDF) is pleased to announce awards totaling more than $1 million for 11 novel investigator-initiated research projects designed to understand the causes of and find a cure for Parkinson's disease.

Two defective genes may cause telomere elongations in cancer cells: Study

Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten.

Single molecule telomerase activator could extend human cell life indefinitely

When expressed (turned on), the gene (hTERT) located on Chromosome number 5p15.33 activates the enzyme telomerase. Human cells can keep living and dividing indefinitely when telomerase is continually present; i.e. the cells become immortal. Telomerase Activation Sciences, Inc. (T.A. Sciences®) announces TA-65® can extend human cell life indefinitely. TA-65® is a single molecule telomerase activator that turns on the Immortality Gene under controlled laboratory conditions.

Scientists mimic dyskeratosis congenita through study of undifferentiated iPS cells

A rare genetic disease called dyskeratosis congenita, caused by the rapid shortening of telomeres, can be mimicked through the study of undifferentiated induced pluripotent stem cells, according to new findings from the Stanford University School of Medicine.

Early exposure to social deprivation and neglect linked to prematurely shortened telomeres in children

Studies in institutionalized Romanian children have found that the length of time spent in conditions of social deprivation and neglect correlates with lower IQ and behavioral problems. A new study, led by researchers at Children's Hospital Boston and Tulane University, shows that early adversity even affects children's chromosomes – prematurely shortening the chromosome tips, known as telomeres, and hastening how quickly their cells "age."

Life expectancy blood test not popular with experts

According to scientists and medical ethicist there are hidden dangers of a new blood test for determining how fast someone is ageing. The test costs £435 test and is due to go on sale to the general public in Britain later this year, measures the length of a person's telomeres, the structures on the tips of the chromosomes which get progressively shorter with age. Short telomeres are linked with age-related diseases and premature death.
