MU researchers find identical DNA codes in different plant species

COLUMBIA, Mo. -- Analyzing massive amounts of data officially became a national priority recently when the White House Office of Science and Technology Policy announced the Big Data Research and Development Initiative. A multi-disciplinary team of University of Missouri researchers rose to the big data challenge when they solved a major biological question by using a groundbreaking computer algorithm to find identical DNA sequences in different plant and animal species. "Our algorithm found identical sequences of DNA located at completely different places on multiple ...

Changes in monkeys' social status affect their genes

DURHAM, N.C. -- A female's social status affects how her genes turn on and off, and those who rank higher tend to be healthier -- so long as their social status doesn't decline, according to a study of rhesus macaques published in the April 9 Proceedings of the National Academy of Sciences. The study is the first to use an experimental approach to observe how gene expression patterns across a range of genes correlate with an animal's social dominance. It estimates that gene expression can predict the social status of an individual with 80 percent accuracy. "Our study ...

Social stress that molds monkey immune system helps researchers understand how stress affects humans

If a monkey's social status changes, her immune system changes along with it say researchers who conducted the study with rhesus macaques at the Yerkes National Primate Research Center. This finding may have implications for how the stress of low socioeconomic status affects human health and how individuals' bodies adapt after a shift in their social environment. The results are published this week in the Proceedings of the National Academy of Sciences Early Edition. Researchers led by Jenny Tung, PhD, say they can predict a rhesus macaque's rank within a small group ...

2 genetic deletions in human genome linked to the development of aggressive prostate cancer

NEW YORK (April 9, 2012 ) -- An international research team led by Weill Cornell Medical College investigators have discovered two inherited-genetic deletions in the human genome linked to development of aggressive prostate cancer. The findings, published online today in the Proceedings of the National Academy of Sciences (PNAS), indicate a man's risk of developing prostate cancer either triples or quadruples, depending on the genetic variant they inherit. In the study, one genetic deletion is shown to affect the functioning of a known gene, while the other, found ...

Diet may treat some gene mutations

BETHESDA, MD -- April 9, 2012 -- Scientists have moved a step closer to correcting some unhealthy gene mutations with diet, according to a new research report appearing in the April 2012 issue of the journal GENETICS (http://www.genetics.org/). Researchers from the University of California, Berkeley, determined variations and responses to vitamin treatment in the human cystathionine beta synthase gene, which when defective, causes the disease homocystinuria, an inherited metabolic disorder sometimes treatable with vitamin B6. After the analysis, scientists correlated specific ...

Summer temperature variability may increase mortality risk for elderly with chronic disease

Boston, MA – New research from Harvard School of Public Health (HSPH) suggests that seemingly small changes in summer temperature swings—as little as 1°C more than usual—may shorten life expectancy for elderly people with chronic medical conditions, and could result in thousands of additional deaths each year. While previous studies have focused on the short-term effects of heat waves, this is the first study to examine the longer-term effects of climate change on life expectancy. The study will be published online April 9, 2012 in the Proceedings of the National Academy ...

UCF scientists use nanotechnology to hunt for hidden pathogens

Researchers at the University of Central Florida have developed a novel technique that may give doctors a faster and more sensitive tool to detect pathogens associated with inflammatory bowel disease, including Crohn's disease. The new nanoparticle-based technique also may be used for detection of other microbes that have challenged scientists for centuries because they hide deep in human tissue and are able to reprogram cells to successfully evade the immune system. The microbes reappear years later and can cause serious health problems such as seen in tuberculosis ...

Social stress changes immune system gene expression in primates

The ranking of a monkey within her social environment and the stress accompanying that status dramatically alters the expression of nearly 1,000 genes, a new scientific study reports. The research is the first to demonstrate a link between social status and genetic regulation in primates on a genome-wide scale, revealing a strong, plastic link between social environment and biology. In a comparison of high-ranking rhesus macaque females with their low-ranking companions, researchers discovered significant differences in the expression of genes involved in the immune response ...

Immune cells, 'macrophages' become activated by body temperature

Macrophages playing an important role in the immune system eat and fight against pathogens and foreign substances in the very beginning of infection. In this condition, macrophages produce reactive oxygen species for sterilization. However, the relation with the temperature sensor was not previously known.

Penn study cautions use of drugs to block 'niacin flush'

PHILADELPHIA — Niacin, or vitamin B3, is the one approved drug that elevates "good" cholesterol (high density lipoprotein, HDL) while depressing "bad" cholesterol (low density lipoprotein , LDL), and has thereby attracted much attention from patients and physicians. Niacin keeps fat from breaking down, and so obstructs the availability of LDL building blocks. Patients often stop taking niacin because it causes uncomfortable facial flushing, an effect caused by the release of a fat called prostaglandin or (PG)D2. PGD2 is the primary cause of the unwanted vasodilation, ...

Researcher finds faster, cheaper way to cool electronic devices

A North Carolina State University researcher has developed a more efficient, less expensive way of cooling electronic devices – particularly devices that generate a lot of heat, such as lasers and power devices. The technique uses a "heat spreader" made of a copper-graphene composite, which is attached to the electronic device using an indium-graphene interface film "Both the copper-graphene and indium-graphene have higher thermal conductivity, allowing the device to cool efficiently," says Dr. Jag Kasichainula, an associate professor of materials science and engineering ...

Researchers identify genes that may help in ovarian cancer diagnosis and prognosis

Philadelphia, PA, April 9, 2012 – Scientists from Duke University Medical Center have determined that genes acting as molecular "on/off" switches can define clinically relevant molecular subtypes of ovarian cancer, providing ideal potential targets for use in clinical prognostic and diagnostic testing. These bimodal genes can define tumor subtypes that have different overall prognoses and respond to different therapeutic regimens. The researchers' results are published in the May issue of The Journal of Molecular Diagnostics. "We identified a very small set of genes ...

A better tool to diagnose tuberculosis

Up to 30% of the world's population is infected with Tuberculosis (TB), but in many areas of the world, TB diagnosis still relies on insensitive, poorly standardized, and time-consuming methods. A new diagnostic tool, endorsed by the World Health Organization (WHO), may change that. Dr. Thomas Bodmer shows how it's done in the Journal of Visualized Experiments (JoVE). Currently, TB is diagnosed through either a skin test, which produces a small bump on the patient's arm when administered and needs to be checked after 72 hours, and through smear microscopy, a method that ...
