New therapy shows potential for treating Duchenne muscular dystrophy

Researchers at the University of Minnesota Medical School have discovered a new therapy that shows potential to treat people with Duchenne muscular dystrophy, a fatal disease and the most common form of muscular dystrophy in children.

Research details function of key protein in cancer spread

Research led by David Worthylake, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, may help lay the groundwork for the development of a compound to prevent the spread of cancer. The research will be published in the May 29, 2009 issue of the Journal of Biological Chemistry.

People with darker skin might be more susceptible to nicotine addiction

Blacks and others with darker skin might be at greater risk for tobacco addiction than whites and those with lighter skin because the greater the amount of melanin, the coloring pigment in skin, the more nicotine appears to be stored, according to preliminary findings published in the journal Pharmacology, Biochemistry and Behavior, the New York Times reports.

Snoring and sleep apnoea damage the brain

Australian researchers have found that the effects of sleep apnoea on the brain of a sleeping patient are far worse than previously thought.

Biological timekeeper studies reveal new temperature regulator and track clock protein across a day

Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities, according to two studies published May 15.

Discovery of genetic cause of luminal-type tumors

The discovery of tumor-suppressor genes has been key to unlocking the molecular and cellular mechanisms leading to uncontrolled cell proliferation - the hallmark of cancer. Often, these genes will work in concert with others in a complex biochemical system that keeps our cells growing and dividing, disease free.

FHL2 protein regulates blood vessel maintenance

In a study led by Akiko Hata, PhD, of Tufts University School of Medicine, researchers have shown that a protein expressed in the heart, FHL2, inhibits the genes necessary for the quiescence of vascular smooth muscle cells (vSMCs), which line blood vessels.

Loss of stromal protein major new prognostic factor in patients with breast cancer

Reporting online in the American Journal of Pathology, researchers from the Kimmel Cancer Center at Jefferson have implicated the loss of a stromal protein called caveolin-1 as a major new prognostic factor in patients with breast cancer, predicting early disease recurrence, metastasis and breast cancer patient survival.

New tag could enable more detailed structural studies of mammalian proteins

To say our genes are resourceful is a gross understatement. Through ingenious combinations of a paltry 20 amino acids, the basic building blocks of life, genes engineer all of the tissues and organs that are the marvel of our working bodies.

IBM and University of Texas Medical Branch launch effort to find flu drug treatments

IBM and the University of Texas Medical Branch (UTMB) launched an effort using IBM's World Community Grid "virtual supercomputer" to allow laboratory tests on drug candidates for drug-resistant influenza strains and new strains, such as H1N1, in less than a month.

Small molecules might block mutant protein production in Huntington's disease

Molecules that selectively interfere with protein production can stop human cells from making the abnormal molecules that cause Huntington's disease, researchers at UT Southwestern Medical Center have found.

Novel "lab on a tube" monitoring device

The need for improved monitoring of neurotrauma patients has resulted in the development of a prototype of a novel, multitasking "lab on a tube" at the University of Cincinnati (UC).

A systems biology map of iron metabolism

Scientists at the Wake Forest University School of Medicine, the University of Manchester in the United Kingdom, and the Virginia Bioinformatics Institute at Virginia Tech have taken the first steps toward constructing a systems biology map of iron metabolism.

Mitochondrial peptide Humanin linked to neuronal cell survival and regulation of glucose metabolism

Recent studies have shown that the mitochondrial peptide Humanin (HN) protects against neuronal cell death such as happens in Alzheimer's disease.

Scientists make significant strides in identifying cause of bacterial infections

Several bacterial pathogens use toxins to manipulate human host cells, ultimately disturbing cellular signal transduction.

Why an effective vaccine for HIV has proven so elusive

Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled.

How cells control the great divide

A scientist whose work is key to understanding how cancer cells divide and spread in the body is to present advances in his latest research at a public forum to be held at the University of Leicester.

Humanized mouse infected with HIV vaginally and rectally allows testing

The "humanized mouse" developed by Dr. J. Victor Garcia-Martinez has allowed the University of Texas Southwestern physician-scientist to conduct HIV/AIDS studies that would have been impossible without such a small animal model of HIV infection.

Key genetic mechanism a potential key to new class of antibiotics

Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online today as a "paper of the week" in the Journal of Biological Chemistry.
