Scientists study key malaria protein structure to demonstrate how cells grow and move

Researchers from the Walter and Eliza Hall Institute have overturned conventional wisdom on how cell movement across all species is controlled, solving the structure of a protein that cuts power to the cell 'motor'. The protein could be a potential drug target for future malaria and anti-cancer treatments.

Scientists discover protein involved in nerve cell motor-cargo mechanism

With every bodily movement-from the blink of an eye to running a marathon-nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle.

Scientists discover new mechanism behind Salmonella invasion into gut cells

Scientists from the Helmholtz Centre for Infection Research in Braunschweig, Germany have discovered a new, hitherto unknown mechanism of Salmonella invasion into gut cells: In this entry mode, the bacteria exploit the muscle power of cells to be pulled into the host cell cytoplasm.

New state of myosin in cardiac muscle with low ATP turnover rate could decrease metabolic load of myocardium

New insight into the physiology of cardiac muscle may lead to the development of therapeutic strategies that exploit an inherent protective state of the heart. The research, published by Cell Press online on April 19th in the Biophysical Journal, discovers a state of cardiac muscle that exhibits a low metabolic rate and may help to regulate energy use and promote efficiency in this hard-working and vital organ.

New treatment improves immune function in 13-year-old with Wiskott-Aldrich syndrome

In a novel approach that works around the gene defect in Wiskott-Aldrich syndrome, an inherited immune deficiency disorder, researchers used an alternative cell signaling pathway to significantly improve immune function in a 13-year-old boy with the disease.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Biochemical process that lasts a long time causes memory storage

You may remember the color of your loved one's eyes for years. But how?

Science journal publishes CYTK preclinical cardiac myosin activation research results

Cytokinetics, Incorporated announced today the publication of preclinical research in the March 18, 2011 issue of the journal Science regarding the activation of cardiac myosin by an investigational drug candidate, omecamtiv mecarbil, and the potential therapeutic role that this novel mechanism may play for patients with systolic heart failure.

Two studies show how laminin plays a central role in breast cancer development

Laminin, long thought to be only a structural support protein in the microenvironment of breast and other epithelial tissues, is "famous" for its cross-like shape.

Muscle, aptly enough, is born of cellular bullying, and not mutual consent

In fact, according to new research from Johns Hopkins, the fusion of muscle cells is a power struggle that involves a smaller mobile antagonist that points at, pokes and finally pushes into its larger, stationary partner using a newly identified finger-like projection.

75% of cell plasma membrane reversibly endocytosed

In three papers in the January and February issues of the Journal of General Physiology, Don Hilgemann and colleagues have extensively characterized a previously unidentified process by which up to 75% of the cell plasma membrane can be reversibly endocytosed.

Silicon microdevices may provide new way to screen metastatic breast cancer cells

Research by engineers and cancer biologists at Virginia Tech indicate that using specific silicon microdevices might provide a new way to screen breast cancer cells' ability to metastasize.

Researchers identify gene mutation for that is essential for correct protein-processing in cells

A Jackson Laboratory research team led by Professor Patsy Nishina, Ph.D., has identified a mutation in a gene that's essential for correct protein-processing in cells. Defects in protein folding are associated with a variety of abnormalities and diseases.

Researchers discover recycling mechanism of signaling receptors

An international team of researchers led by Carnegie Mellon University's Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a signaling receptor travels back to the cell membrane after it has been activated and internalized.

Researchers discover new way to prevent spread of cancer

Scientists now know that some cancer cells spread, or metastasize, throughout the body the old-fashioned way -- by using their feet. But researchers at Duke Cancer Institute have discovered a way to short-circuit their travels by preventing the development of these feet, called invadopodia. This discovery is even more important because preventing the development of these "feet" also eliminates the action of proteins present in the feet that burn through intact tissue and let cancer cells enter new cells.

Researchers discover central switch that regulates movement of cancer cells

Researchers at the University of Georgia have discovered a central switch that controls whether cells move or remain stationary. The misregulation of this switch may play a role in the increased movement of tumor cells and in the aggressiveness of tumors themselves.

DFG announces establishment of eleven new Collaborative Research Centres

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven new Collaborative Research Centres (CRC) as of 1 January 2011. This decision was made recently by the responsible Grants Committee at its autumn meeting in Bonn. The new CRCs will receive a total of - 94.4 million (including a 20 percent programme allowance for indirect project costs) for an initial funding period of four years.

Jefferson researchers progress in understanding mechanism behind systemic fibrotic disorder

Scientists from the Jefferson Institute of Molecular Medicine of Thomas Jefferson University are now several steps closer to understanding the mechanism behind a novel systemic fibrotic disorder that affects some patients with renal insufficiency who receive imaging contrast agents for MRI. Two of their studies on the disorder appear together in the November issue of the Annals of Rheumatic Diseases.
