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.

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.

Toxic free radical responsible for lung damage due to oxygen therapy

The most toxic free radical appears responsible for much of the lung damage that can result from oxygen therapy in the critically ill or injured, Medical College of Georgia researchers report.

LIMK inhibition blocks collective invasion of tumor cells: Researchers

Researchers have shown that LIM kinase, an important regulator of actin cytoskeleton dynamics, plays a key role in cancer metastasis. The study appears online on September 27 in The Journal of Cell Biology www.jcb.org.

Protein zyxin necessary for maintenance and repair of cell's cytoskeleton

Researchers at Huntsman Cancer Institute (HCI) at the University of Utah have discovered that a protein, zyxin, is necessary for the maintenance and repair of the cell's cytoskeleton, or internal framework, which serves as the muscle and bone of the cell. The research has implications for cancer, as well as other diseases, since alterations in the cytoskeleton are often associated with disease. The research was published in the Sep. 14, 2010, issue of the journal Developmental Cell.

Structural component inside neurons dances when connections are strengthened

Scientists at Emory University School of Medicine have uncovered how a structural component inside neurons performs two coordinated dance moves when the connections between neurons are strengthened.

Pathogens can delay entry into cells to ensure their survival, say researchers

Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure infection success. Pathogens can actually delay their entry into cells to ensure their survival.

Research on myosin II protein can lead to novel treatment for memory disorders

Scientists from the Florida campus of The Scripps Research Institute have discovered a mechanism that plays a critical role in the formation of long-term memory. The findings shed substantial new light on aspects of how memory is formed, and could lead to novel treatments for memory disorders.

Motor proteins play critical role in stabilization of long-term memories

Functioning much like gears in a machine, cellular motor proteins are critical to dynamic functions throughout the body, including muscle contraction, cell migration and cellular growth processes. Now, neuroscientists from UC Irvine and the Florida campus of The Scripps Research Institute report that motor proteins also play a critical role in the stabilization of long-term memories. The findings add an unexpected dimension to the story of how memories are encoded and suggest new targets for therapeutic interventions.

TRPV4 activity vital to prevent skin dehydration

Japanese research group led by Prof. Makoto Tominaga and Dr. Takaaki Sokabe (National Institute for Physiological Sciences: NIPS) found that TRPV4 ion channel in skin keratinocytes is important for formation and maintenance of barrier function to prevent dehydration. Their finding was reported in the Journal of Biological Chemistry.
