Nobel Prize discovery opens new perspectives for detection and prevention of age-related diseases

This year's Nobel Prize in Physiology or Medicine was awarded to three American scientists Elizabeth Blackburn, Carol Greider and Jack Szostak for the discovery of "how chromosomes are protected by telomeres and the enzyme telomerase”. The research contributed to the understanding of how telomeres protect chromosomes from degradation and identified telomerase, the enzyme that preserves telomere length and integrity.

Emotionally abused children may face accelerated cellular aging as adults

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.

Cytoskeleton plays a critical role to bring chromosome pairs together: Study

Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. Yet, how the cell precisely choreographs these chromosomal interactions is a long-standing question.

Researchers find link between telomeres and longevity

A team led by researchers at Albert Einstein College of Medicine of Yeshiva University has found a clear link between living to 100 and inheriting a hyperactive version of an enzyme that rebuilds telomeres - the tip ends of chromosomes. The findings appear in the latest issue of the Proceedings of the National Academy of Sciences.

Cellular mechanisms that may impact immune functions in the elderly discovered

Investigators discover cellular mechanisms that may impact the decline of both innate and adaptive immune functions that increase the susceptibility to various infectious agents, cancer and diseases in the elderly say experts at the annual meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Miami Beach, Fla.

DKC establishes link between genetic mutation affecting telomerase function and human disease

The human genetic disease dyskeratosis congenita (DKC) is an autosomal dominant disease that leads to abnormalities in tissues with a rapid cell turnover - the skin, nails, bone marrow, lungs and gut. Patients with DKC experience life-threatening symptoms. Bone marrow failure increases their risk of fatal infections and cancer. Many die before the age of 30 and management of the disease is limited to trying to treat its symptoms.

National Science Foundation funded 2009 Nobel laureates felicitated

The National Science Foundation (NSF) congratulates the 2009 Nobel laureates, particularly those who have received NSF funding over the years: Jack W. Szostak, who shared the prize in physiology or medicine; Thomas A. Steitz, who shared the prize in chemistry; and Elinor Ostrom and Oliver E. Williamson who earned the Sveriges Riksbank Prize in economic sciences in memory of Alfred Nobel 2009.

61 institutions awarded grants for cancer research from American Cancer Society

The American Cancer Society, the largest non-government, not-for-profit funding source of cancer research in the United States, has awarded 94 new national research and training grants totaling $45,097,000 to 61 institutions nationwide in the second of two grants cycles for 2009. The grants go into effect beginning January 1, 2010.

New study on behaviour of telomeres during cell division in cancerous human cells

A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.

Research reveals that large non-coding RNA in mammals play an important role in telomere maintenance

A team of researchers from The Wistar Institute have shown that a large non-coding RNA in mammals and yeast plays a central role in helping maintain telomeres, the tips of chromosomes that contain important genetic information and help regulate cell division. Since this RNA also facilitates the formation of DNA at telomeres-a process that can protect aging cells and destabilize tumor cells-manipulating its expression may be useful in treating cancer and other diseases.

Protein plays unexpected role protecting chromosome tips

A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell.

Protein DNA repair complex key to avoiding DNA repair mistakes

As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows.

Handle with care: Telomeres resemble DNA fragile sites

Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack.

Study gives clues to how ultra-rare adrenocortical cancer forms

At the ends of chromosome are special pieces of DNA called telomeres. Think of it as the little tip that caps off a shoelace. The telomeres send signals to the cells to let them know it's the end point, not a break that should be repaired.

Researchers target telomeres to attack tumors

Hoping to develop more effective long-term attacks on cancer, researchers at the Indiana University School of Medicine are conducting the first human tests of a breast cancer drug regimen that includes a compound meant to force cancer cells to grow old and die.

African sleeping sickness parasite breaks its own DNA to avoid detection

The parasite Trypanosoma brucei, which causes African sleeping sickness, is like a thief donning a disguise.

The egg makes sure that sperm don't get too old

In contrast to women, men are fertile throughout life, but research at the Sahlgrenska Academy, University of Gothenburg, Sweden, has now shown that a fertilising sperm can get help from the egg to rejuvenate. The result is an important step towards future stem cell therapy.
