redOrbit Staff & Wire Reports - Your Universe Online A subtle alternation in DNA involving one single-letter change in the genetic code is enough to generate blond hair in men and women, researchers from Howard Hughes Medical Institute and the Stanford University Medical Center report in Sunday’s edition of the journal Nature Genetics. According to developmental biology professor Dr. David Kingsley and his colleagues, a molecule essential to stem cell function plays a vital role...

University of Utah Health Care Scientists at the University of Utah (U of U), the University of Texas MD Anderson Cancer Center in Houston and colleagues have developed a powerful tool called pVAAST that combines linkage analysis with case control association to help researchers and clinicians identify disease-causing mutations in families faster and more precisely than ever before. In a study in Nature Biotechnology, the researchers describe cases in which pVAAST (the pedigree Variant...

Findings to Enhance System That Is Transforming Genetic Research Charlottesville, VA (PRWEB) May 27, 2014 Researchers at the University of Virginia School of Medicine have devised a way to detect unintended side effects of manipulating genes using a revolutionary new system that is sweeping the scientific world by storm. The gene targeting system, called CRISPR, allows editing of genetic information at specifically targeted sites in the genome. UVA’s new approach reveals the system has...

Genetic Legacy Of A Rare Brain Disorder Traced Back To The Ottoman Empire

redOrbit Staff & Wire Reports - Your Universe Online Scientists have detected a previously unknown neurodegenerative disorder stemming from a single mutation in one lone individual who lived approximately 16 generations ago during the days of the Ottoman Empire in Turkey, according to two studies appearing in Thursday’s edition of the journal Cell.  [ 1 ] [ 2 ] Two international teams of researchers, each of which was performing DNA sequencing of thousands of Turkish children...

Rainbow Trout Genome Sequenced By International Team Of Researchers
2014-04-22 14:58:22

By Eric Sorensen, Washington State University Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve. The 30-person team, led by Yann Guiguen of the French National Institute for Agricultural Research, reports its findings this week in Nature Communications. Recent doubling enables study The...

Researchers at UC Davis have identified a new feature of the genetic mutation responsible for the progressive neurodegenerative disorder, fragile X-associated tremor/ataxia syndrome (FXTAS) — the formation of "R-loops," which they believe may be associated with the disorder's neurological symptoms, such as tremors, lack of balance, features of Parkinsonism, and cognitive decline. The finding suggests that the R-loops may be potential targets for drug development, said Paul Hagerman,...

Genetic evidence supports role of gene family in cancer development Researchers have found a major piece of genetic evidence that confirms the role of a group of virus-fighting genes in cancer development. Our understanding of the biological processes that cause cancer is limited. UV light and smoking are two well-understood cancer-causing processes. Exposure to either of these processes causes distinguishable patterns of genetic damage, or 'signatures', on the genome that can lead to...

These genes could explain why some women with high-risk mutations suffer from cancer while others do not Today we know that women carrying BCRA1 and BCRA2 gene mutations have a 43% to 88% risk of developing from breast cancer before the age of 70. Taking critical decisions such as opting for preventive surgery when the risk bracket is so wide is not easy. Spanish National Cancer Research Centre (CNIO) researchers are conducting a study that will contribute towards giving every woman far...

Ribosomes are essential for life, generating all of the proteins required for cells to grow. Mutations in some of the proteins that make ribosomes cause disorders characterized by bone marrow failure and anemia early in life, followed by elevated cancer risk in middle age. These disorders are generally called "ribosomopathies." How can ribosomopathies first appear as diseases caused by too few cells, but later turn into diseases caused by too many cells? This paradox has puzzled the...
