The tachykinin receptor 3 gene has been linked to alcohol and cocaine dependence
The search for genes associated with alcohol dependence has recently been extended to the tachykinin receptor 3 gene, located within a broad region on chromosome 4q. Researchers have found that seven of the nine single nucleotide polymorphisms -- DNA sequence variations -- in the 3' region of TACR3 have a significant association with AD as well as... view more...

Bioclocks work by controlling chromosome coiling
In recent years, scientists have discovered that biological clocks help organize a dizzying array of biochemical processes in the body. Despite a number of hypotheses, exactly how the microscopic pacemakers in every cell in the body exert such a widespread influence has remained a mystery. view more (2007-11-26)
Scientists identify a gene that may suppress colorectal cancer
In today's online edition of Genome Research, a husband-and-wife research team from Thomas Jefferson University report the discovery of a gene that, when mutated, may suppress colorectal cancer. view more (2007-03-22)
Leading reason for corneal transplants comes into focus
Guided by families with an unusual number of cases, scientists at Johns Hopkins have discovered the genetic origins of at least one form of Fuchs corneal dystrophy, FCD, the leading reason for corneal transplantation in the United States. view more (2006-10-13)
New clues to how sex evolves
Sex is a boon to evolution; it allows genetic material from parents to recombine, giving rise to a unique new genome. But how did sex itself evolve\\\ view more (2006-12-05)
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)
Boys more likely when pregnancy takes longer
The longer it takes to get pregnant, the more chance there is of having a boy, finds a study in this week's BMJ. view more (2005-12-19)
Identification of genetic markers for ulcerative colitis could lead to treatment
An international consortium of researchers, including major contribution from a team led by Dr. John D. Rioux, a professor of medicine at the Université de Montréal and the Montreal Heart Institute, has identified genetic markers associated with risk for ulcerative colitis. view more (2009-01-09)
Tendency to hair loss inherited from the mother
The male sex hormones really do seem to play a decisive role in causing hair loss in men. This has been confirmed by scientists from the universities of Bonn and Düsseldorf. Their studies show that specific changes in the genetic 'construction manual' of the androgen receptor may result in premature balding. Androgens are hormones which play... view more... (2005-05-20)
Autism gene identified by researchers at Yale working with a global research consortium
Yale School of Medicine autism experts Fred Volkmar, M.D. and Ami Klin are part of a global research consortium from 19 countries to identify a gene and a region of a chromosome that may lead to autism in children. view more (2007-03-14)
Does the desire to consume alcohol and tobacco come from our genetic makeup?
Alcohol and smoking can be harmful, if not deadly. While the desire for these substances can be due to environmental cues, genomic factors also play an important role. view more (2007-08-13)
U-M researchers identify gene involved in breast cancer
Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the development of an aggressive form of breast cancer. view more (2007-07-27)
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)
UVa-led team uncovers important secret in gene replication
A team of researchers led by University of Virginia Health System geneticists has uncovered a major secret in the mystery of how the DNA helix replicates itself time after time. view more (2007-06-14)
Manchester researchers identify gene behind rheumatoid arthritis
University of Manchester researchers have identified a genetic variant in a region on chromosome 6 that is associated with rheumatoid arthritis (RA), the most common inflammatory arthritis affecting 387,000 people in the UK. view more (2007-11-05)
Slicing chromosomes leads to new insights into cell division
By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division. view more (2009-06-01)
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. view more (2009-07-10)
Molecule links Down syndrome to Alzheimer's
Researchers from the Institute of Psychiatry at King's College London have identified a molecule that could be targeted to treat the cognitive impairment in people with Down syndrome. view more (2005-12-06)
St. Jude study yields secrets of chromosome movement
Investigators at St. Jude Children's Research Hospital have used the lowly yeast to gain insights into how a dividing human cell ensures that an identical set of chromosomes gets passed on to each new daughter cell. view more (2007-06-18)
New genetic markers for ulcerative colitis identified, researchers report in Nature Genetics
An international team led by University of Pittsburgh School of Medicine researchers has identified genetic markers associated with risk for ulcerative colitis. view more (2009-01-05)
