Scientists develop new mathematical model to understand CML better

Doctors can now understand better chronic myeloid leukaemia (CML), including how it responds to therapy, thanks to a new mathematical model for the disease, developed by scientists in Portugal, Belgium and the United States. The work, to be published in the June edition of the journal Haematologica, also reveals that current therapies - which are not believed to cure CML - with the right protocol can actually get rid of the disease, and provides guidelines on how to do that.

Researchers have traced protein that stops cells from becoming cancerous

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.

Gene variants associated with human biological ageing identified

Scientists announced today (7 Feb) they have identified for the first time definitive variants associated with biological ageing 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.

Omega-3 fatty acids may protect against cellular aging in coronary heart disease patients

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.

Organization of the brain's dictionary

Two hundred years ago, archaeologists used the Rosetta Stone to understand the ancient Egyptian hieroglyphs. Now, a team of Carnegie Mellon University scientists has discovered the beginnings of a neural Rosetta Stone. By combining brain imaging and machine learning techniques, neuroscientists Marcel Just and Vladimir Cherkassky and computer scientists Tom Mitchell and Sandesh Aryal determined how the brain arranges noun representations. Understanding how the brain codes nouns is important for treating psychiatric and neurological illnesses.

Gene modification of human embryonic stem cells may yield potential treatments for genetic diseases

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.

Preclinical data of Geron's telomerase inhibitor drug published

Geron Corporation today announced the publication of preclinical data demonstrating that its telomerase inhibitor drug, imetelstat (GRN163L), inhibited telomerase activity and reduced tumor size in xenograft models of glioblastoma, and inhibited the activity of glioblastoma stem cells in culture.

Experimental lung cancer drug promising against brain cancer glioblastoma and prostate cancer

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.

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.

CompuCyte expands iGeneration line of imaging cytometers to include four-laser versions

CompuCyte Corporation, the pioneer in the field of imaging cytometry instrumentation and the leading supplier of laser scanning cytometers, announced that it has expanded its state-of-the art iGeneration line of imaging cytometers to include four-laser versions of the iCyte®, iCys® and iColor® systems.

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.
