Myocardits is an inflammation of the heart muscles that is a major cause of heart failure in young patients. In some cases, the disease is caused by viral infection, but in other patients it is linked to an autoimmune attack on the heart muscle. There are few effective treatment options for myocarditis, in part because the molecular mechanisms that underlie the defect are poorly defined. In this paper, researchers led by Myra Lipes, at the Joslin Diabetes Center in Boston, Massachusetts, used...

Joslin Diabetes Center research may point toward new ways to diagnose and treat heart disease in people with type 1 diabetes People with type 1 diabetes, whose insulin-producing cells have been destroyed by the body's own immune system, are particularly vulnerable to a form of inflammatory heart disease (myocarditis) caused by a different autoimmune reaction. Scientists at Joslin Diabetes Center have revealed the exact target of this other onslaught, taking a large step toward potential...

Novel mechanistic approach to directly modulating muscle contractility may represent a promising strategy to treat systolic heart failure Cytokinetics, Incorporated (Nasdaq: CYTK) 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...

NIH researchers present work today at Biophysical Meeting in Baltimore Researchers have created the first mouse models of human MYH9 genetic disorders, which cause several problems -- including enlarged platelets and sometimes fatal kidney disease. The MYH9 gene makes non-muscle myosin II-A protein. This protein plays a critical role in helping cells move to their correct home during embryonic development. Later in life, the protein continues its involvement in cell migration, cell-cell...

Presentation today at Biophysical Society Meeting in Baltimore From grinding heavy metal to soothing ocean waves, the sounds we hear are all perceptible thanks to the vibrations felt by tiny molecular motors in the hair cells of the inner ear. Researchers at the University of Pennsylvania School of Medicine have now identified the mechanism by which a single amino acid change can disrupt the normal functioning of one of the critical components of that physiology -- a molecular motor protein...

New research sheds light on the interaction between the semi-flexible protein tropomyosin and actin thin filaments. The study, published by Cell Press on February 15th in the Biophysical Journal, provides the first detailed atomic model of tropomyosin bound to actin and significantly advances the understanding of the dynamic relationship between these key cellular proteins. Tropomyosin is a long protein that associates with actin, a highly conserved thin filament protein found in organisms...

Potentially big implications for cancer control By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single cell into two daughter cells. The protein, called 14-3-3, sits at an intersection where it integrates converging signals from within the cell and cues cell shape change and, ultimately, the splitting that allows for normal and...

Researchers have shown that LIM kinase (LIMK), 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. Cancer metastasis is a multi-stage process that starts with the invasion of tumor cells into their surrounding tissue. The ability of metastatic cells to invade requires reorganization of the actin-myosin cytoskeleton, which is controlled by a sophisticated network of...

Findings add new dimension to how memories are encoded, suggest new therapeutic targets 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...

New findings could lead to better treatments 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. The study was published as the cover story of the journal Neuron on August 26, 2010. In the study, the scientists found that a main...
