Selection in European populations of genes regulated by FOXP2, a key factor in development and language Researchers have designed a method that can universally test for evolutionary adaption, or positive (Darwinian) selection, in any chosen set of genes, using re-sequencing data such as that generated by the 1000 Genomes Project. The method identifies gene sets that show evidence for positive selection in comparison with matched controls, and thus highlights genes for further functional...

Researchers have recently discovered that an expansion of DNA in patients with the common neurodegenerative disorder Fragile X-associated Tremor syndrome causes the production of an abnormal protein that is toxic to neurons. The findings, which are reported online April 18 in the Cell Press journal Neuron, suggest an unexpected process by which DNA expansions might lead to neurodegenerative diseases–including Huntington's disease and ALS. This discovery reveals a common feature among...

Researchers at Karolinska Institutet in Sweden have identified a new so-called pseudogene that regulates the tumor-suppressing PTEN gene. They hope that this pseudogene will be able to control PTEN to reverse the tumor process, make the cancer tumor more sensitive to chemotherapy and to prevent the development of resistance. The findings, which are published in the scientific journal Nature Structural and Molecular Biology, can be of significance in the future development of cancer drugs....

Women More Talkative Than Men Because Thier Brain Is Designed That Way
2013-02-22 12:17:19

Michael Harper for redOrbit.com — Your Universe Online We´ve all heard the oft-repeated statistics about women talking more than men. And to back up those statistics, one previous study has shown that a part of the brain responsible for processing communication is simply larger in a woman than a man. Now, a new study adds to those claims by moving a step further, showing that the female brain is actually designed with communication in mind. Performed by doctors at the...

Findings could lead to greater understanding of sex differences in language acquisition Male rat pups have more of a specific brain protein associated with language development than females, according to a study published February 20 in The Journal of Neuroscience. The study also found sex differences in the brain protein in a small group of children. The findings may shed light on sex differences in communication in animals and language acquisition in people. Sex differences in early...

Fragile X Syndrome Linked To Nearly 100 Autism Genes
2012-12-13 15:28:13

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from Duke University Medical Center and Rockefeller University recently discovered that the gene responsible for fragile X syndrome is connected to almost 100 other genes that have been linked to autism. While researchers have long been aware of a relationship between fragile X syndrome and autism, this is the first time that they have begun to trace out the exact genetic pathways that link the two disorders...

Researchers from the University of Geneva demonstrate that, in this type of lesion, the rate of progression from a precancerous state to the tumor stage accelerates over time The causes underlying the development of certain types of common cancers have not yet been elucidated. In order to better determine the origin and the sequence of events responsible for the onset of colon cancer, the teams led by Thanos Halazonetis and Stylianos Antonarakis, professors at the University of Geneva...

Treatment with SIRT2 inhibitor reduced neurodegeneration, behavioral symptoms Treatment with a novel agent that inhibits the activity of SIRT2, an enzyme that regulates many important cellular functions, reduced neurological damage, slowed the loss of motor function and extended survival in two animal models of Huntington's disease. The study led by Massachusetts General Hospital (MGH) researchers will appear in the Dec. 27 issue of Cell Reports and is receiving advance online release....

The Herpesviridae, a large family of DNA viruses, causes disease in animals and humans. Members of this family are known as herpesviruses. They all share a common structure where they are composed of relatively large double-stranded, linear DNA genomes encoding 100-200 genes encased within an icosahedral protein cage called the capsid. The whole particle is known as a virion. They are all nuclear-replicating. When a viral particle contacts a cell with specific types of receptor molecules...
