Massive and consistent changes in inflammatory gene expression seen in trauma, burns

Serious traumatic injuries, including major burns, set off a "genomic storm" in human immune cells, altering around 80 percent of the cells' normal gene expression patterns. In a report to appear in the December Journal of Experimental Medicine, members of a nationwide research collaborative describe the initial results of their investigation into the immune system response to serious injury, findings which have overturned some longstanding assumptions.

Scientists discover genetic trigger that makes stem cells differentiate in nose epithelia

University of California, Berkeley, neuroscientists have discovered a genetic trigger that makes the nose renew its smell sensors, providing hope for new therapies for people who have lost their sense of smell due to trauma or old age.

Ecstasy drug associated with chronic changes in human brain

Recreational use of Ecstasy - the illegal "rave" drug that produces feelings of euphoria and emotional warmth - is associated with chronic changes in the human brain, Vanderbilt University investigators have discovered.

Study shows how mothering can strengthen offspring's immune system in brain

An attentive, nurturing mother may be able to help her children better resist the temptations of drug use later in life, according to a study involving the University of Adelaide.

Researchers sequence entire transcriptome of mouse neural retina

The population of Eric Morrow's seminar "Neurogenetics and Disease" comprises mainly undergraduates who were skipping down the halls of their elementary schools when the first drafts of human genome sequences were published. When Morrow, assistant professor of biology, recently asked the class how to find the mutation behind a disease, a hand shot up in the back of the class to signal the answer: "Sequence the patient's genome."

Next generation personal genomic testing now widely available

The era of widely available next generation personal genomic testing has arrived and with it the ability to quickly and relatively affordably learn the sequence of your entire genome. This would include what is referred to as the "exome," your complete set of protein-coding sequences.

Racial differences in inflammation might explain survival paradox among dialysis patients

In the general population, African Americans die at earlier ages than whites, but among patients on dialysis, African Americans live longer than whites. A new study helps explain this paradox and could help prolong the lives of all patients on dialysis.

Relaxin improves poor blood flow and kidney function in a rat model of PKD

After a four-week course of the vasodilator hormone relaxin, kidney function and blood flow immediately improved in lab rats genetically altered to model polycystic kidney disease (PKD), a life-threatening genetic disorder, according to research presented on Dec. 6 at the American Society for Cell Biology Annual Meeting in Denver.

New research on bed bug's ability to withstand genetic bottleneck of inbreeding

New research on the bed bug's ability to withstand the genetic bottleneck of inbreeding, announced today at the American Society of Tropical Medicine and Hygiene (ASTMH) annual meeting, provides new clues to explain the rapidly growing problem of bed bugs across the United States and globally.

Scientists help uncover evolutionary history of TAS2R38 bitter taste receptor gene

Long the bane of picky eaters everywhere, broccoli's taste is not just a matter of having a cultured palate; some people can easily taste a bitter compound in the vegetable that others have difficulty detecting. Now a team of Penn researchers has helped uncover the evolutionary history of one of the genes responsible for this trait.

New NHGRI funding plan sharpens focus of Genome Sequencing Program on medical apps

A new funding plan by the National Human Genome Research Institute (NHGRI) sharpens the focus of its flagship Genome Sequencing Program on medical applications. In addition to continuing on-going studies, the four-year, $416 million plan launches new efforts to find causes of rare inherited diseases and accelerate the use of genome sequence information in the medical care of patients.

Web-based video game players contribute to analysis of DNA sequences

Thousands of video game players have helped significantly advance our understanding of the genetic basis of diseases such as Alzheimer's, diabetes and cancer over the past year. They are the users of a web-based video game developed by Dr. J-r-me Waldispuhl of the McGill School of Computer Science and collaborator Mathieu Blanchette.

King's College London submits first clinical grade xeno-free hES cell lines to the UKSCB

Stem cell scientists at King's College London will announce they have submitted to the UK Stem Cell Bank (UKSCB) their first clinical grade human embryonic stem (hES) cell lines that are free from animal-derived products, known as 'xeno-free' stem cells.

Scientists understand how nervous system becomes wired during early development

Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development.

Study evaluates whether genetic GST polymorphisms increase risk of ALD in alcoholics

It has been widely observed that only a small percentage of alcoholics develop cirrhosis of the liver, the most advanced form of alcoholic liver disease (ALD); the reason why all alcoholics do not develop such disease is not known. The present study from Spain, that includes original work and a meta-analysis, evaluates whether genetic polymorphisms that determine levels of glutathione-S-transferases (GST) relate to the risk of developing ALD among alcoholics.

Inbreeding in bed bugs one key to massive increases in infestations

New research on the bed bug’s ability to withstand the genetic bottleneck of inbreeding, announced today at the American Society of Tropical Medicine and Hygiene (ASTMH) annual meeting, provides new clues to explain the rapidly growing problem of bed bugs across the United States and globally. After mostly disappearing in the US in the 1950s, the common bed bug (Cimex lectularius) has reappeared with a vengeance over the past decade. These stubborn pests have developed a resistance to the insecticides, known as pyrethroids, commonly used against them.

Biosensors can detect oxidant production in living organism

Arterial calcification and coronary heart disease, neurodegenerative diseases such as Parkinson's and Alzheimer's, cancer and even the aging process itself are suspected to be partially caused or accelerated by oxidative stress. Oxidative stress arises in tissues when there is an excess of what are called reactive oxygen species.
