Research sheds light on origins of "junk" DNA

In experiments with transgenic mice, University of Pennsylvania School of Medicine researchers discovered the remaining steps in the complicated process of how the largest class of jumping genes replicates and inserts themselves within the human genome.

Human body has a unique immune system response to foreign DNA

The human body has a unique immune system response to foreign DNA, suggesting that DNA viruses and RNA viruses are detected by different mechanisms, Yale School of Medicine researchers report this week in Immunity.

New method to find new metabolites

Ever since penicillin, a byproduct of a fungal mold, was discovered in 1929, scientists have scrutinized fungi for other breakthrough drugs. As reported Jan. 20 in the Journal of Chemistry and Biology, a team led by a University of Wisconsin-Madison researcher has developed a new method that may speed the ongoing quest for medically useful compounds in fungi.

Protein amplifies DNA injury signals - cues genetic repair mechanism to prevent tumors

A Mayo Clinic-led research collaboration has discovered that the protein MDC1 amplifies weak DNA injury signals so genetic repair can begin.

Cloned stem cells are perfectly normal

Scientists generally agree that all cloned animals are biologically flawed. But they don't agree about what that means for stem cells derived from cloned embryos, the basis for therapeutic cloning.

Genome-wide prediction of mammalian enhancers for control of gene expression

Molecular biologists, developmental biologists and computer scientists at the Universtity of Helsinki, Finland, came together to advance towards cracking the code for how gene expression is controlled. The results of this work are published in Cell, in January 2006.

Physiogenomic resources for rat models of heart, lung and blood disorders

Every year, heart disease claims an estimated 7 million lives, according to the World Health Organization. Scientists have struggled to pinpoint the precise genes behind this complex disease. Now, however, they have a new research ally: the designer rat.

Slow human evolution revealed by worm genome

Humans have retained genomic characteristics of a very ancient ancestor that have been lost in simpler animals such as the fly, indicating that humans are one of the most slowly evolving species. This is the finding of an international team of scientists including Dr David Ferrier of Oxford’s Department of Zoology published in a recent edition of the journal Science.

Scientists describe phenomenon in the human genome called transcription-induced chimerism

In the January issue of the journal Genome Research, two teams of scientists describe a widespread phenomenon in the human genome called transcription-induced chimerism (TIC), where two adjacent genes produce a single, fused RNA transcript.

Researchers discover that large segments of human genome are devoid of mobile DNA elements called transposons

Scientists from the University of Queensland, Australia report in the journal Genome Research that large segments of the human genome are conspicuously devoid of ubiquitous mobile DNA elements called transposons.

Dog gene map may help explain human diseases

U.S. scientists say a detailed analysis of the dog genome answers such questions as how dogs of a different breed still belong to the same species, and may also explain some aspects of human health and biology.

UK DNA Banking Network

Doctors and scientists nationwide wil for the first time be able to join together over the internet to start the search for genes that underlie a range of chronic diseases.

Exploiting biology's own chemical toolbox...

Exploiting biology's own chemical toolbox, researchers have developed a new technique that will allow them to modify specific sequences within a DNA molecule. The approach will not only help reveal the impact of biochemical alterations to DNA, but could have far-reaching implications for DNA-based medical diagnosis and nanobiotechnology.

Loss of genes on chromosome 1 or 11 raises the risk of death from the children's cancer neuroblastoma

A new study reports that a loss of genes on chromosome 1 or chromosome 11 raises the risk of death from the children's cancer neuroblastoma, even when other indicators seem to point to a lower-risk form of the disease.

Genetic influences behind Dupuytren's disease or contracture

A crippling condition that can result in sufferers losing their fingers is to be investigated by scientists in one of the most detailed studies into the genetic causes of the disease ever carried out.

High blood pressure research advances efforts to tailor drugs to individual patients

Having high blood pressure and a particular genetic alteration dramatically increases the risk of heart attack, stroke or death, and may explain why some hypertensive patients fare worse than others - even if they take the same medication, University of Florida researchers announced.

Haphazard activation of secondary signaling pathways may fuel cancer's genesis

When found at abnormally high concentrations, two proteins implicated in many human cancers have the potential to spur indiscriminate biochemical signaling inside cells, chemists at Harvard University have found.

Researchers can now identify patients likely to respond to cancer drug therapy

Researchers at UCLA's Jonsson Cancer have identified key characteristics in certain deadly brain tumors that make them 51 times more likely to respond to a specific class of drugs than tumors in which the molecular signature is absent.

New method to find deadly malaria parasite

Researchers at UCSD have discovered that the single-cell parasite responsible for an estimated 1 million deaths per year worldwide from malaria has protein "wiring" that differs markedly from the cellular circuitry of other higher organisms

Mechanisms of evolution may be associated with disease

By comparing the human genome with that of the chimpanzee, man's closest living relative, researchers have discovered that chunks of similar DNA that have been flipped in orientation and reinserted into chromosomes are hundreds of times more common in primates than previously thought.
