Virologists surprised to discover that a common herpesvirus hidden in chromosomes of some people can be reactivated to infectious form Tampa, FL -- Human herpesvirus 6 (HHV-6) infects nearly 100 percent of humans in early childhood, and the infection then lasts for the rest of a person's life. Now, a team led by Peter Medveczky, MD, a professor in the Department of Molecular Medicine at the University of South Florida (USF), has discovered that in some individuals, HHV-6 causes such a...

Finding could be basis for developing new cancer therapies In the dominoes that make up human cells, researchers at the University of Michigan Comprehensive Cancer Center have traced another step of the process that stops cells from becoming cancerous. It starts with the enzyme telomerase, which affects the caps, or telomeres, at the end of a chromosome. Telomeres shorten over time. But telomerase prevents this from happening, making the cell immortal. If cancer is triggered in the cell, the...

Discovery has important implications for the understanding of cancer and age associated diseases Scientists announced Sunday they have identified for the first time definitive variants associated with biological aging in humans. The team analyzed more than 500,000 genetic variations across the entire human genome to identify the variants which are located near a gene called TERC. The study in Nature Genetics published Feb 7 by researchers from the University of Leicester and King's College...

Patients with coronary heart disease who had higher omega-3 fatty acid blood levels had an associated lower rate of shortening of telomere length, a chromosome marker of biological aging, raising the possibility that these fatty acids may protect against cellular aging, according to a study in the January 20 issue of JAMA. Several studies have shown increased survival rates among individuals with high dietary intake of marine omega-3 fatty acids and established cardiovascular disease. The...

Biologists have developed an efficient way to genetically modify human embryonic stem cells. Their approach, which uses bacterial artificial chromosomes to swap in defective copies of genes, will make possible the rapid development of stem cell lines that can both serve as models for human genetic diseases and as testbeds on which to screen potential treatments, they say. "This will help to open up the whole human embryonic stem cell field. Otherwise, there's really few efficient ways you can...

An experimental drug currently being tested against breast and lung cancer shows promise in fighting the brain cancer glioblastoma and prostate cancer, researchers at UT Southwestern Medical Center have found in two preclinical studies. The drug's actions, observed in isolated human cells in one trial and in rodents in the other, are especially encouraging because they attacked not only the bulk of the tumor cells but also the rare cancer stem cells that are believed to be responsible for...

A new study shows that people blessed with youthful faces are more likely to live to a ripe old age than those who look older than their years, BBC News reported. Appearance alone can predict survival, according to Danish scientists who studied 387 pairs of twins. The study asked nurses, trainee teachers and peers to guess the age of the twins from mug shots, and those rated younger-looking tended to outlive their older-looking sibling. The British Medical Journal reports that the...

Intensive exercise prevented shortening of telomeres, a protective effect against aging of the cardiovascular system, according to research reported in Circulation: Journal of the American Heart Association. Researchers measured the length of telomeres "” the DNA that bookends the chromosomes and protects the ends from damage "” in blood samples from two groups of professional athletes and two groups who were healthy nonsmokers, but not regular exercisers. The telomere shortening...

Researchers from Brown University and Butler Hospital have determined that children who suffer physical or emotional abuse may be faced with accelerated cellular aging as adults. The findings are published online in the journal Biological Psychiatry. A print version of the articled is also expected. Children who suffer physical or emotional abuse may be faced with accelerated cellular aging as adults, according to new research from Butler Hospital and Brown University. The findings, which are...

Doctor in biology from the UPNA, Ms Gúmer P©rez Garrido studied and described for the first time how the telomeres and adjacent sequences of the oyster fungus (Pleurotus ostreatus) are organized. Her PhD thesis, "Organization of the telomeric and subtelomeric regions of the basidiomycete Pleurotus ostreatus." The aim was to get to know more thoroughly how the genetic material of this type of fungus is organized and compare it with other organisms. In fact, the telomere...
