First report on how patterns of 5-hmC's distribution change in mouse brain during development

In 2009, the DNA alphabet expanded. Scientists discovered that an extra letter or "sixth nucleotide" was surprisingly abundant in DNA from stem cells and brain cells.

'Deep sequencing' technology identifies new target area for depression

Scientists at the Texas Biomedical Research Institute and Yale University have identified a new target area in the human genome that appears to harbor genes with a major role in the onset of depression.

Study: Many fetal expression changes are reversed immediately after birth

The "switching on" or expression of specific genes in the human genome is what makes each human tissue and each human being unique. A new study by researchers at the Johns Hopkins Bloomberg School of Public Health, the Lieber Institute for Brain Development, and the National Institute of Mental Health found that many gene expression changes that occur during fetal development are reversed immediately after birth.

Research breakthrough in lung regeneration

Scientists at A*STAR'S Genome Institute of Singapore (GIS) and Institute of Molecular Biology (IMB), have made a breakthrough discovery in the understanding of lung regeneration. Their research showed for the first time that distal airway stem cells (DASCs), a specific type of stem cells in the lungs, are involved in forming new alveoli to replace and repair damaged lung tissue, providing a firm foundation for understanding lung regeneration.

Scientists discover Leishmania parasite with juggling chromosomes

Scientists found a deadly parasite with some of its chromosomes in duplicate, others in triplicate, while still others are present four or even five times. Moreover, the copy number varies between individuals. Such a bizarre occurrence has never before been found in nature, in any organism. As a rule, chromosomes should come in couples. The scientists, from the Institute of Tropical Medicine (ITG) and the Wellcome Trust Sanger Institute, made the striking discovery while deciphering the genetic code of a series of Leishmania-parasites.

Scientists describe how protein acts as courier in cell signaling pathways

Normal development, from fertilized egg to adult organism, depends on each cell receiving proper instructions from its environment. In response to such incoming information, receptors on a cell's surface send signals to the nucleus that tweak gene expression and control cellular function.

Functional link between IKBKE and Akt activation in breast cancer

Publishing in the current issue of The Journal of Biological Chemistry (Vol. 286, No 43), researchers at Moffitt Cancer Center in Tampa, Fla., have discovered additional mechanisms of "Akt" activation and suggest a component of that activation mechanism - inhibitor of nuclear factor kappa-B kinase subunit epsilon (IKBKE) - could be targeted as a therapeutic intervention for treating cancer.

New discoveries on drug resistance in Leishmania

Two remarkable discoveries were today revealed by researchers into genome analysis of Leishmania parasites. These results uncovered a surprising level of variation at the genome structure level.

C21orf91 gene associated with susceptibility to herpes simplex labialis

Investigators have identified a human chromosome containing a specific gene associated with susceptibility to herpes simplex labialis (HSL), the common cold sore.

AD risk genes impact Aβ toxicity in neurons

In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.

Beneficial intestinal bacteria can activate immune cells and trigger MS

Multiple sclerosis is caused by a combination of genetic and environmental factors. For a long time, pathogens were believed to be such external influences. According to scientists from the Max Planck Institute of Neurobiology in Martinsried, however, it is apparently not harmful bacteria that trigger multiple sclerosis, but beneficial ones - specifically, the natural intestinal flora, which every human being needs for digestion.

BROCA test identifies 12 gene mutations linked to ovarian and related cancers

More patients with ovarian carcinoma carry cancer-predisposing mutations, and in more genes, than previously thought.

New genomic approach can trace food-borne bacteria with unprecedented accuracy

With salmonella-tainted ground turkey sickening more than 100 people and listeria-contaminated cantaloupes killing 15 this year, the ability to detect outbreaks of food-borne illness and determine their sources has become a top public health priority.

Scientists studying complete genetic profiles of centenarians to find the secret of longevity

Scientists have announced Wednesday that they would examine some of the oldest citizens with one of the newest scientific tools: whole-genome sequencing, the deciphering of a person’s complete collection of DNA. They speculate that DNA from very old healthy people could offer clues to how they lived so long. And that could one day lead to medicines to help people stay disease-free longer.

Study provides details on genetics behind many metabolic diseases

In what is so far the largest investigation of its kind, researchers uncovered a wide range of new insights about common diseases and how they are affected by differences between two persons' genes. The results from this study could lead to highly targeted, individualized therapies.

BGI, UC Davis partner to create new sequencing facility in Sacramento

The University of California, Davis, and BGI, the world's largest genomic institute, based in China, have signed a historic agreement that will change the landscape of genomic sciences in California and the Western states, and foster critical breakthroughs in the areas of food security and human, animal and environmental health.

C. sinensis parasite lacks enzymes required for fatty acid biosynthesis

The human liver fluke Clonorchis sinensis affects more than 35 million people in South East Asia and 15 million in China. Infection by this parasite causes clonorchiasis. Repeated or chronic infection can lead to serious disease of the liver, gall bladder or bile ducts, including the frequently fatal bile duct cancer - cholangiocarcinoma.

Sewage provides perfect ecosystem for studying diversity of uncharacterized viral populations

Raw sewage provides a perfect ecosystem for studying the diversity of viral populations that remain uncharacterized. This is one of the principal conclusions of a study published in the journal mBio by a team comprising experts from the UB's Laboratory of Water and Food Viral Pollution, Washington University and the University of Pittsburgh, under the direction of James Pipas.

X Prize Foundation offers $10 million for innovative diagnostic device

Jim, I'm a doctor, not a device developer! Remember how in Star Trek, Dr. McCoy could point his tricorder at things and magically -; oops, I mean, "scientifically" -; determine all kinds of chemical components and medical diagnoses? The X Prize Foundation -; best known for offering prizes for space flight and cheap genome decoding -; is about to put up $10 million for the invention of a medical device in the spirit of that tricorder: It must be able to diagnose 15 common medical conditions within three days, with no intervention from a health care professional.
