Researchers determine genetic cause of Timothy syndrome

...ism. Cell culture studies of the mutated version of the channel revealed that it did not react properly to block calcium flow at the appropriate time. This abnormality could explain the lethal cardiac arrhythmias in Timothy syndrome patients, said Keating. Further genetic analyses of the ...

...ings of the National Academy of Science. The print version of the research paper will appear in the Sept. 28 issue of the journal. Human immunodeficiency virus, commonly known as HIV, is known to cause AIDS. The virus attacks the body's immune system, making the body vulnerable to infections and certain canc...

Genes expose secrets of sex on the side

...turally accepted fashion, Wilder said. "The modern version that we generally don't find offensive is that men tend to remarry and have more children much more often than women do." The team's research also overturns the long-accepted idea that, on average, women's genes traveled farther from their birt...

Genetic analysis rewrites salamander's evolutionary history

...e larval stage, emerging from the egg as a smaller version of an adult. The new family tree shows, however, that some terrestrial salamanders regained their larval stage after moving back to the water. This may have happened in three separate lineages of Plethodontids, which is surprising for a seemingly com...

Molecule awakens and maintains neural connections

... When the researchers blocked the activity of the version of the Dasm1 gene found in rats, they found dendrite arborization to be drastically reduced in cultured brain cells. The researchers also studied the effects of Dasm1 on the maturation of neuronal connections, or synapses. Newly formed, immature syn...

Recent evolution at a single gene may have brought down heart disease risk in some human groups

... of arteries. Individuals with the low-expression version of the gene are slightly more prone to atherosclerosis, the narrowing of the arteries associated with the accumulation of plaque in the arterial walls. The new research shows that the high-expression variant increased rapidly in frequency in the anci...

Genetic clues found for common congenital brain disorder

...t of the mice that had one normal and one abnormal version of both ZIC1 and ZIC4 had abnormalities in the cerebellum that were very similar to the brains of patients with Dandy-Walker. They also lacked coordination and were unable to right themselves if they fell over. Although the authors conclude that "h...

Heartless worms hold clues to cardiac arrhythmias, sudden death

The mutation, unc-103, causes profound neuromuscular defects, including a pharyngeal pumping defect that Petersen noticed as she learned to work with the worms. "I remember the first time I saw it (the pumping defect)," she said. "It looked...

Using statistics to decipher secrets of natural mutation

Basically, the technique enables them to feed in sequence information from genomes of different organisms and discern patterns that can distingu...

Nerve cells 'guided' to repair spinal damage: Technique

...rds. The technique, outlined in the July 6 online version of Biomaterials, involves imbedding a series of fibrous rods into a gel substance and then dissolving the rods, leaving a series of longitudinal channels. These channels are then injected with peptides, molecules that stimulate cell adhesion and migr...

The new technique, and older gene-silencing methods that have given rise in recent years to a multi-million dol...

Social benefits of wound healing may not make any difference in animals with multiple partners

Social contact benefited the monogamous mice corticosterone levels were lower, and wounds also healed faster. But separated pairs lost this benefit, even if the mice in a separated pair could still se...
