Universitat Autonoma de Barcelona researchers first to clone mice in Spain
Researchers at the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB) are the first to have cloned mice in Spain. Cloe, Cleo and Clona are three female brown-coloured mice and were born respectively on 12 May, 3 June and 10 June. view more (2009-06-12)
Telomerase inhibition - a cancer therapy that is not always what it seems
Telomerase is a protein involved in cancer where it is present in 85 to 90% of all cases. Taking advantage of this fact, over the last years multiple new approaches have appeared that aim to inhibit telomerase activity as a new treatment strategy in human cancer. However, in the latest issue of the journal Oncogene scientists reveal that in some... view more... (2004-05-25)
New Genetic Screening Method Predicts Behaviour Of Wilms' Tumour In Children (p 385)
Researchers in this week's issue of The Lancet have developed a new method that can accurately predict how tumours will behave by the genes they express. Dr Kathy Pritchard-Jones and her colleagues, from the Institute of Cancer Research, UK, studied children who had the commonest form of Wilms' tumour with favourable histology. Overall, these... view more... (2002-07-31)
After dinosaurs, mammals rise but their genomes get smaller
Evidence buried in the chromosomes of animals and plants strongly suggests only one group -- mammals -- have seen their genomes shrink after the dinosaurs' extinction. view more (2009-07-28)
U-M scientists identify major psoriasis susceptibility gene
University of Michigan scientists have found a common genetic variation in an immune system gene that makes people much more likely to develop psoriasis - a disfiguring inflammatory skin disease. view more (2006-03-16)
Study finds protein is required for human chromosome production
Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified an elusive protein that performs a necessary step in the production of human chromosomes. view more (2005-10-13)
New chromosomal abnormality identified in leukemia associated with Down syndrome
Researchers identified a new chromosomal abnormality in acute lymphoblastic leukemia (ALL) that appears to work in concert with another mutation to give rise to cancer. This latest anomaly is particularly common in children with Down syndrome. view more (2009-10-19)
Single molecular 'mark' seen as pivotal for genome compaction in spores and sperm
In higher order animals, genetic information is passed from parents to offspring via sperm or eggs, also known as gametes. In some single-celled organisms, such as yeast, the genes can be passed to the next generation in spores. view more (2006-09-18)
National Science Foundation congratulates Nobel Laureates in medicine/physiology, chemistry and economics
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... view more... (2009-10-15)
Movement of chromosome in nucleus visualized
The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around. view more (2006-04-18)
New gene for dyslexia located
No gene for dyslexia has been isolated until now, although scientists have long suspected a genetic basis for the disorder and have even roughly mapped the region of the brain likely to be involved. The researchers anticipate that they will now be able to clone the genetic sequence and so gain important insights into the processes involved in... view more... (1999-09-02)
Scientists harvest answers from genome of grain fungus
Evil forces thrive in an unstable environment. At least, that's the picture being painted in the first waves of data being reaped from the genome sequence of the fungal plant pathogen, Fusarium graminearum. view more (2007-09-07)
Toward a faster prenatal test for Down syndrome
Scientists in California are reporting an advance toward rapid testing for pre-natal detection of Down syndrome and other birth defects that involve an abnormal number of chromosomes. view more (2007-09-19)
Enhanced skin cancer risk linked to defects in cellular aging controls
Cell lifespan is limited by telomeres, DNA sequences that cap chromosomes and control the number of times a cell may be copied. A new study reported in Disease Models & Mechanisms (DMM), dmm.biologists.org, describes how telomere dysfunction in skin cells can lead to increased skin cancer risk and pigmentation. view more (2009-02-23)
Study links dietary folate intake to genetic abnormalities in sperm
Healthy men who report lower levels of the nutrient folate in their diets have higher rates of chromosomal abnormalities in their sperm, according to a new study by researchers at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory. view more (2008-03-20)
Female human embryos adjust the balance of X chromosomes before implantation
Dutch researchers have found the first evidence that a process of inactivating the X chromosome during embryo development and implantation, which was known to occur in mice but unknown in humans, does, in fact, take place in human female embryos prior to implantation in the womb. view more (2009-06-30)
Researchers use chemical from medicinal plants to fight HIV
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised. view more (2008-11-10)

A statistical approach to studying genetic variation promises to shed new light on the history of human migration. view more (2008-05-23)
Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned
Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed. view more (2007-08-17)
