Virginia Tech Virginia Tech researchers discover which genetic changes pass the test of extremely different ecologies Scientists have long puzzled over the genetic differences between fruit flies that live hardly a puddle jump apart in a natural environment known as "Evolution Canyon" in Mount Carmel, Israel. Now, an international team of researchers led by scientists with the Virginia Bioinformatics Institute at Virginia Tech has peered into the DNA of these closely related flies...

Johns Hopkins Medicine Understanding of mechanism could lead to new drug treatment A genetic variant linked to sudden cardiac death leads to protein overproduction in heart cells, Johns Hopkins scientists report. Unlike many known disease-linked variants, this one lies not in a gene but in so-called noncoding DNA, a growing focus of disease research. The discovery, reported in the June 5 issue of The American Journal of Human Genetics, also adds to scientific understanding of the...

Large sections of the genome that were once referred to as “junk” DNA have been linked to human heart failure, according to research from Washington University School of Medicine in St. Louis. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn’t code for proteins. But emerging research in recent years has revealed that many of these sections of the genome produce RNA molecules that, despite not being proteins, still have important...

Non-coding DNA sequences found in all plants may have undiscovered roles in basic plant development and response to the environment DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the particular protein that a short segment of DNA, known as a gene, will encode. But in many organisms, there is much more DNA in a cell than...

Stretches of DNA called retrotransposons, often dubbed "junk DNA", might play an important role in schizophrenia. In a study published today in the journal Neuron, a Japanese team revealed that LINE-1 retrotransposons are abnormally abundant in the schizophrenia brain, modify the expression of genes related to schizophrenia during brain development, and may be one of the causes of schizophrenia. Retrotransposons are short sequences of DNA that autonomously amplify and move around the...

By using a new analysis method, researchers at Karolinska Institutet and Science for Life Laboratory (SciLifeLab) in Sweden have found close to one hundred novel human gene regions that code for proteins. A number of these regions are so-called pseudogenes, which may be linked to cancer. The expectation is now that this recently developed protein analysis method, published in the scientific journal Nature Methods, will open up a whole new field of research. All information about the human...

For the first time, scientists have used new technology which analyses the whole genome to find the cause of a genetic disease in what was previously referred to as 'junk DNA' For the first time, scientists have used new technology which analyses the whole genome to find the cause of a genetic disease in what was previously referred to as "junk DNA". Pancreatic agenesis results in babies being born without a pancreas, leaving them with a lifetime of diabetes and problems digesting food. In...

UC Riverside geneticists show the COPIA-R7 transposon enhances the immunity of its host against a pathogenic microorganism Transposons are DNA elements that can multiply and change their location within an organism's genome. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk DNA." Also referred to as transposable elements and jumping genes, they are snippets of "selfish DNA" that spread in their host genomes serving no other biological purpose but...

Canadian-led study will help scientists identify key genomic regions in canola, other food plants What allows certain plants to survive freezing and thrive in the Canadian climate, while others are sensitive to the slightest drop in temperature? Those that flourish activate specific genes at just the right time -- but the way gene activation is controlled remains poorly understood. A major step forward in understanding this process lies in a genomic map produced by an international...

Rebekah Eliason for redOrbit.com - Your Universe Online At the center of most human cells, genomic DNA lies tucked away within a nucleus. However, a surprisingly small percentage of this DNA actually codes for genes that can be translated into proteins. In fact, some researchers estimate as much as 98 percent of this DNA seems to have a puzzling lack of purpose, leading many to refer to it as 'junk DNA.' However, a new study from UC San Francisco now emphasizes the potentially important...


Word of the Day
cacodemon
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
'Cacodemon' comes from a Greek term meaning 'evil genius.'
