UCLA researchers examine human embryonic stem cell genome
Stem cell researchers from UCLA used a high resolution technique to examine the genome, or total DNA content, of a pair of human embryonic stem cell lines and found that while both lines could form neurons, the lines had differences in the numbers of certain genes that could control such things as individual traits and disease susceptibility. view more (2008-03-28)
Double success for Instituto Gulbenkian de Ciencia scientists working on chromosome segregation
Lars Jansen's work on the formation of the centromere, a key cellular structure in powering and controlling chromosome segregation and accurate cell division, has just earned him a paper in Nature Cell Biology and a prestigious EMBO installation grant, of 50,000 euro per year, for a maximum of five years. view more (2009-07-01)
A balancing act between the sexes
Recent research at the European Molecular Biology Laboratory (EMBL) reveals new insights into how cells achieve equality between the sexes. view more (2006-03-17)
Rodent's bizarre traits deepen mystery of genetics, evolution
A shadowy rodent has potential to shed light on human genetics and the mysteries of evolution. view more (2006-09-18)
Stowers Institute's Workman Lab discovers novel histone demethylase protein complex
The Stowers Institute's Workman Lab has discovered a novel histone demethylase protein complex characterized in work published today in Molecular Cell. view more (2008-12-08)
Large multicenter study suggests new genetic markers for Crohn's disease
What is believed to be the largest study of its kind for the genetic roots of inflammatory bowel diseases has suggested new links to Crohn's Disease as well as further evidence that some people of Jewish descent are more likely to develop it. view more (2008-03-27)
Support for chromosomal theory of cancer found in cancers' development of drug resistance
Thirty-six years into the war on cancer, scientists have not only failed to come up with a cure, but most of the newer drugs suffer from the same problems as those available in the pre-war days: serious toxicity, limited effectiveness and eventual resistance. view more (2007-06-28)
A test to prove a woman has been raped
Stray Y chromosomes can confirm an allegation of rape A TEST that can prove a woman has been raped even if no sperm are found should be widely adopted, the first large-scale study suggests. After the trauma of rape, women who report it have to undergo a medical examination to look for sperm. But the... view more... (2002-02-27)
ADHD medications do not cause genetic damage in children
In contrast to recent findings, two of the most common medications used to treat attention deficit hyperactivity disorder (ADHD) do not appear to cause genetic damage in children who take them as prescribed, according to a new study by researchers at the National Institutes of Health (NIH) and Duke University Medical Center. view more (2008-11-20)
Mice cloned from skin cells
Healthy and viable mice that survive until adulthood have, for the first time, been cloned from adult stem cells. Scientists from Rockefeller University, including Howard Hughes Medical Institute investigator Elaine Fuchs, used cells called keratinocyte stem cells, which represent a new model system for cloning. view more (2007-02-13)
Baylor Human Genome Sequencing Center marks end of sequencing effort with chromosome 3
The sequencing of human chromosome 3 announced in the current issue of the journal Nature represents a milestone for the Baylor College of Medicine Human Genome Sequencing Center - the final stage of its multi-year project to sequence the human genome. view more (2006-04-27)
USC researchers identify DNA mutation that occurs at beginning point of T-cell lymphoma
Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a key mechanism that causes chromosomes within blood cells to break-an occurrence that marks the first step in the development of human lymphoma. view more (2009-06-12)
Advances in the characterisation of the oyster mushroom genes
The oyster mushroom (Pleurotus ostreatus), apart from reducing cholesterol and having anticancerogenic properties, is characterised for its capacity for breaking down cellulose. Finding out which genes are responsible for this activity - the reason why the fungus is sometimes used as a decontaminating agent, was the aim of the PhD thesis by... view more... (2005-03-15)
Mothers transmit DNA through daughters only
Scientists have argued whether or not the often-studied mitochondrial DNA molecule is clonally inherited. It is with assuming clonal inheritance this type of DNA has been used to track the origin of modern human as well as to draw pictures of genetic relationships among other animals and plants. The conflict has now been solved by two evolutionary... view more... (2001-09-06)
Flipped genetic sequences illuminate human evolution and disease
By comparing the human genome with that of the chimpanzee, man's closest living relative, researchers have discovered that chunks of similar DNA that have been flipped in orientation and reinserted into chromosomes are hundreds of times more common in primates than previously thought. view more (2005-10-26)
DNA repair teams' motto: 'To protect and serve'
When you dial 911 you expect rescuers to pull up at your front door, unload and get busy-not park the truck down the street and eat donuts. view more (2006-11-17)
A Broken Stress Response System Can Contribute to Gleevec Resistance
New clues to why some kinds of leukemia are more aggressive and deadly than others are coming from research examining the types of genetic damage that allow some blood cells to grow out of control, scientists report. view more (2006-04-21)
Dogs, Humans, put Heads Together to Find Cure for Brain Cancer
Pinpointing the genes involved in human brain cancer can be like looking for a needle in a haystack, and sometimes the needle you find may not be the right one. view more (2009-07-07)
PGD could save women from the agony of repeated miscarriages
Women who suffer repeated unexplained miscarriages can be helped to have babies if preimplantation genetic diagnosis (PGD) is carried out on their embryos before they are placed in the womb. Ms Carmen Rubio told the European Society of Human Reproduction and Embryology annual conference in Vienna today (Monday 1 July) that her research showed that... view more... (2002-06-29)
New map of variation in maize genetics holds promise for developing new varieties
A new study of maize has identified thousands of diverse genes in genetically inaccessible portions of the genome. New techniques may allow breeders and researchers to use this genetic variation to identify desirable traits and create new varieties that were not easily possible before. view more (2009-11-20)
