Tiny molecule controls stress-induced heart disease
A tiny snippet of RNA, a chemical cousin of DNA, controls damage to the heart under several types of stress, researchers at UT Southwestern Medical Center have found. view more (2007-03-23)
Study offers clues to beating hearing loss
Researchers at the University of Leeds have made a significant step forward in understanding the causes of some forms of deafness. view more (2009-03-04)
Ancient protein offers clues to killer condition
More than 600 million years of evolution has taken two unlikely distant cousins - turkeys and scallops - down very different physical paths from a common ancestor. But University of Leeds researchers have found that a motor protein, myosin 2, remains structurally identical in both creatures. view more (2008-05-13)
Molecular motor works by detecting minute changes in force
Researchers at the University of Pennsylvania School of Medicine discovered that the activity of a specific family of nanometer-sized molecular motors called myosin-I is regulated by force. The motor puts tension on cellular springs that allow vibrations to be detected within the body. view more (2008-07-10)
'Muscle' protein drives prostate cancer
Researchers at the Johns Hopkins Kimmel Cancer Center have for the first time implicated the muscle protein myosin VI in the development of prostate cancer and its spread. view more (2006-11-09)
St. Jude scientists discover a new mechanism controlling neuronal migration
The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital. view more (2009-07-16)
Image of myosin-actin interaction revealed in cover story of Molecular Cell
Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction. view more (2005-09-30)
Dividing cells 'feel' their way out of warp
Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs - even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes. view more (2009-09-11)
A new focus for the mechanism of nerve growth
Researchers at Yale shed new light on the mechanism of nerve cell growth by identifying novel functions for a molecular "motor" protein, myosin-II, according to an article in the March issue of Nature Cell Biology. view more (2006-03-20)
A balancing act in Parkinson's disease: Phosphorylation of alpha-synuclein
Both genetic and pathologic data indicate a role for the neuronal protein alpha-synuclein in Parkinson disease. view more (2009-10-13)
From mother to daughters: A central mystery in cell division solved
Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have identified a key step required for cell division in a study that could help improve therapies to treat cancer. view more (2008-12-09)
Molecular motors may speed nutrient processing
Matthew Tyska, Ph.D., recalls being intrigued, from the first day of his postdoctoral fellowship in 1999, with a nearly 30-year-old photograph. It was an electron micrograph that showed the internal structures of an intestinal cell microvillus, a finger-like protrusion on the cell surface. Microvilli are common features on the epithelial cells... view more... (2007-05-31)
Researchers find level of special protein is critical to proper formation of muscles
Proper formation of the proteins that power heart and skeletal muscle seems to rely on a precise concentration of a "chaperone" protein known as UNC-45, according to a new study. view more (2007-04-25)
What Are Muscle Proteins Doing in the Nucleus?
The proteins actin and myosin have a firm place in the muscles where they are responsible for contraction. While recent investigations have shown that they are also found in the nucleus, it has been unclear to date just what they are doing there. Now an international team of investigators headed by Professor Dr. Ingrid Grummt, head of the Division... view more... (2005-02-01)
Potential therapy for congenital muscular dystrophy
Current research suggests laminin, a protein that helps cells stick together, may lead to enhanced muscle repair in muscular dystrophy. view more (2008-12-30)
Anti-malarials most effective in lupus patients genetically at risk of high levels of TNF-alpha
Anti-malarial drugs are most effective in people with lupus who are genetically predisposed to high levels of tumour necrosis factor alpha and low levels of the cytokine IL-10. view more (2006-02-13)
The Structural Basis of Familial Hypertrophic Cardiomyopathy is Revealed
Familial Hypertrophic Cardiomyopathy (FHC), the leading cause of sudden death in athletes and young people, is a genetic disorder of the heart that is characterized by an increased thickness in tissue of the left ventricle. view more (2007-11-12)
Movement of chromosome in nucleus visualized
The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around. view more (2006-04-18)
Lessons from yeast: A possible cure for Parkinson's disease?
Parkinson disease (PD) is a debilitating and lethal neurodegenerative disease, for which there is currently no cure. It is caused by the progressive loss of nerve cells that produce the chemical dopamine and is characterized by the accumulation of abnormal aggregates of a protein called alpha-syn in these dopaminergic nerve cells. view more (2008-08-15)
TNF-alpha antagonist stops inflammation-induced colon cancer in its tracks
Individuals with the inflammatory bowel disease ulcerative colitis are at increased risk of developing colon cancer. New data generated by Naofumi Mukaida and colleagues at Kanazawa University, Japan, identified a central role for the soluble factor TNF-alpha in the development of colon cancer in mice in which inflammation of the bowel was induced... view more...
