Keck Foundation awards UF $1M to study how proteins in cells are made

The Center for NeuroGenetics at the University of Florida has received a competitive $1 million grant from the W.M. Keck Foundation to study a new idea that challenges conventional understanding of how proteins in cells are made, and their impact on inherited diseases.

TGF-β molecule ramps up the immune system in some cases and suppress it in others

Loyola researchers are reporting surprising findings about a molecule that helps ramp up the immune system in some cases and suppress it in others.

New drug to detect beta-amyloid plaques may help diagnose AD earlier

Use of a new drug to detect the beta-amyloid plaques in the brain that are hallmark signs of Alzheimer's disease may help doctors diagnose the disease earlier, according to research that will be presented as part of the Emerging Science program (formerly known as Late-Breaking Science) at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012.

High blood sugar in combination with high insulin levels causes fatty deposits in the heart

The impaired substrate metabolism of diabetes patients is often expressed in an increase in fatty deposits in the cells of the heart muscle. Until now, the exact cause of this was unknown. Now, researchers at the MedUni Vienna in the Division of Endocrinology and Metabolism of MedUni Vienna in cooperation with the MR Centre of Excellence Vienna have shown that high blood sugar in combination with high levels of insulin - not an influx of fats - results in such deposits within a few hours.

Seminar series on issues related to intervention, implementation science in aging

A seminar series focusing on issues related to intervention and implementation science in aging is the latest interdisciplinary initiative at the Johns Hopkins University School of Nursing (JHUSON) Center for Innovative Care in Aging.

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

Panel discussion on personalized medicine at USciences

Advances in fields such as genetics and genomics have created new opportunities for personalized medicine applications in clinical practice and the healthcare delivery. This integration raises important questions about how personalized medicine can best help patients without increasing costs and improving health outcomes.

Changes in thromboxane synthase may lead to hypertension in women with preeclampsia

Virginia Commonwealth University School of Medicine researchers have discovered that changes in the gene expression of a key enzyme may contribute to high blood pressure and increase susceptibility to forming blood clots in pregnant women with preeclampsia.

DEP exposure suppresses function of phagocytic immune cells

A team of researchers, led by Dr. Stephan Schwander, of the University of Medicine and Dentistry of New Jersey - School of Public Health (UMDNJ-SPH), has determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.

Scientists identify which T. gondii strains are linked with severe illness in U.S. infants

Scientists have identified which strains of the Toxoplasma gondii parasite, the cause of toxoplasmosis, are most strongly associated with premature births and severe birth defects in the United States.

Study examines cellular and molecular organization of human and mouse brain

Scientists at the Allen Institute for Brain Science have identified similarities and differences among regions of the human brain, among the brains of human individuals, and between humans and mice by analyzing the expression of approximately 1,000 genes in the brain.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Biologists decipher novel functions of metal-binding molecule nicotianamine

In order to survive, plants should take up neither too many nor too few minerals from the soil. New insights into how they operate this critical balance have now been published by biologists at the Ruhr-Universit-t in a series of three papers in the journal The Plant Cell. The researchers discovered novel functions of the metal-binding molecule nicotianamine.

$Researchers identify 32 genetic regions associated with osteoporosis, fracture$

Researchers identify 32 genetic regions associated with osteoporosis, fracture

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, MD, DSc. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease. Many, but not all, of the regions encode proteins involved in pathways known to involve bone health.

Two research studies on genetic components of Alzheimer's

Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.

New genes may explain individual differences in brain size and intelligence

In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease.

Researchers identify new mechanism by which colon cancer develops

A team of researchers at Case Western Reserve University School of Medicine have identified a new mechanism by which colon cancer develops. By focusing on segments of DNA located between genes, or so-called "junk DNA," the team has discovered a set of master switches, i.e., gene enhancer elements, that turn "on and off" key genes whose altered expression is defining for colon cancers.

The key to treating AML may lie within FTL3 gene mutations

The key to treating one of the most common types of human leukemia may lie within mutations in a gene called FLT3, according to new research led by physician-scientists at the University of California, San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center.
