Three new species of lemurs identified
Researchers have identified three new species of lemurs, the small, big-eyed primates native to the island of Madagascar. view more (2006-02-23)
Human and chimp genomes reveal new twist on origin of species
The evolutionary split between human and chimpanzee is much more recent - and more complicated - than previously thought. view more (2006-05-18)
Let's Stick Together - A Protein Protects Chromosome Bonds
The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects. The project of a team of the University of Vienna funded by the Austrian Science Fund (FWF) contributes to the Campus... view more... (2005-03-29)
Why do people with Down syndrome have less cancer?
Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. view more (2009-05-21)
UVA studies potential target for skin cancer treatment
When normal skin cells become a melanoma tumor, they sometimes turn on genes not usually found in the skin. view more (2006-10-04)
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)
Dartmouth researchers find new protein function
A group of Dartmouth researchers has found a new function for one of the proteins involved with chromosome segregation during cell division. view more (2009-01-09)
Vet medicine researcher examines link between cancer, Down syndrome
here's new hope for breast cancer research, and it's coming from a very unlikely place. Researchers at the Texas A&M University College of Veterinary Medicine & Biomedical Sciences recently published articles in the journals Molecular and Cellular Biology and Carcinogenesis indicating that a protein long suspected to play a role in Down... view more...

Low levels of brain chemical may lead to obesity, NIH study of rare disorder shows
A brain chemical that plays a role in long term memory also appears to be involved in regulating how much people eat and their likelihood of becoming obese, according to a National Institutes of Health study of a rare genetic condition. view more (2008-08-28)
When you've doubled your genes, what's 1 chromosome more or less?
An individual with Down syndrome and a male calico cat have one thing in common-each has an extra chromosome. For animals, most instances of an extra chromosome result in birth defects or even death, but plants are another matter entirely. view more (2009-09-15)
Gene profiling can single out the worst cases of multiple myeloma and guide therapy
Multiple myeloma patients vary widely in how they respond to treatment, but now researchers at the Myeloma Institute for Research and Therapy at the University of Arkansas for Medical Sciences have identified a small subset of genes whose activity could predict high-risk cases and potentially guide therapy in the future. view more (2007-09-19)
Study links attempted suicide with genetic evidence identified in previous suicide research
A Johns Hopkins-led study has found evidence that a genetic tendency toward suicide has been linked to a particular area of the genome on chromosome 2 that has been implicated in two additional recent studies of attempted suicide. view more (2007-02-20)
Mouse model aids discovery of novel melanoma metastasis gene
Researchers from Dana-Farber Cancer Institute have identified a novel gene that facilitates the spread of malignant melanoma, a life-threatening skin cancer, using a technique they say can speed the discovery of hard-to-find cancer genes. view more (2006-06-30)
Stanford study uses genetic evidence to trace ancient African migration
Stanford University researchers peering at history's footprints on human DNA have found new evidence for how prehistoric people shared knowledge that advanced civilization. view more (2008-08-05)
NYU biologists identify gene that coordinates two cellular processes
A team of biologists at New York University's Center for Comparative Functional Genomics has uncovered a dual role for the gene mel-28. The gene plays a part in ensuring that chromosomes are divided properly during cell division and it is required for nuclear envelope function. view more (2006-09-06)
SPECIFIC GENE MUTATION LINKED TO CROHN'S DISEASE (pp 1902, 1925)
Genetic susceptibility to Crohn's disease is likely to be the result of an insertion mutation into a specific gene on chromosome 16, conclude authors of a fast-track study published in this week's issue of THE LANCET. In 1996, genetic linkage of inflammatory bowel disease (IBD) to chromosome 16 was established. The recently identified NOD2 gene... view more... (2001-06-13)
New research finds possible genetic link to cause of pregnancy loss and disorders
Scientists at the University of Tennessee, Knoxville, and Lawrence Berkeley National Laboratory (LBNL) have published new findings about a cause of a condition at the root of genetic disorders such as Down Syndrome, pregnancy loss and infertility. view more (2009-07-22)
New clues to the genetic of epilepsy
Two specific areas in chromosome 7 and chromosome 16 have been associated with photosensitivity, an epilepsy-related trait, by a team of European scientists in the January issue of Human Molecular Genetics. Photosensitivity or photoparoxysmal response (PPR) is associated with the most common epilepsy of genetic origin -Idiopathic Generalised... view more... (2005-01-04)
Is DNA Repair a Substitute for Sex?
Birds and bees may do it, but the microscopic animals called bdelloid rotifers seem to get along just fine without sex, thank you. What's more, they have done so over millions of years of evolution, resulting in at least 370 species. These hardy creatures somehow escape the usual drawback of asexuality - extinction - and the MBL's David Mark... view more... (2008-04-03)
'Ageing gene' could be passed on via X chromosome (p 507)
An observational study in this week's issue of THE LANCET sheds more light on the theory that ageing is associated with a shortening of chromosomes in somatic (ie. non-reproductive) cells. Results of the study suggest that the gene responsible for telomere shortening is inherited via the X chromosome. Previous research including a 2003 Lancet... view more... (2004-02-11)
