Published in the Proceedings of the National Academy of Sciences, the Study by Erkan Tuzel and Scientists at UMass Amherst Provides New Insights into a Cellular System Whose Failure Can Lead to Neurodegenerative Diseases and Cancer. Worcester, MA (PRWEB) December 14, 2012 The interior of an animal cell is like a small city, with factories–called organelles–dedicated to manufacturing, energy production, waste processing, and other life functions. A network of intercellular...

Approximately 250,000 people in the United States suffer from muscular dystrophy, which occurs when damaged muscle tissue is replaced with fibrous, bony or fatty tissue and loses function. Three years ago, University of Missouri scientists found a molecular compound that is vital to curing the disease, but they didn't know how to make the compound bind to the muscle cells. In a new study, published in the Proceedings of the National Academies of Science, MU School of Medicine scientists Yi...

Biologists have identified a new molecular player in asymmetric cell division, a protein named She1 whose role wasn't known before - This is important for self-renewal of stem cells and ensures that daughter cells have different fates and functions Recently biologists at the University of Massachusetts Amherst led by Wei-lih Lee have identified a new molecular player in asymmetric cell division, a regulatory protein named She1 whose role in chromosome- and spindle positioning wasn't known...

JUPITER, Fla., Oct. 10, 2012 /PRNewswire/ -- Dr. Jerry Jacobson, biophysicist and inventor, announced today the results of studies on the effect of extremely low intensity electromagnetic fields on the restoration of forelimb grip strength, and radial nerve ultrastructure in mice with induced motor neuropathy. After administration of neurotoxin, mice persisted to exhibit a 56% decrease in grip strength; and radial nerve electron micrographs showed axonal demyelination, inactive mitochondria...

Mechanism For Organ Placement Shared By Human Cells, Plants, Worms And Frogs

New research identifies special protein that determines what goes where As organisms develop, their internal organs arrange in a consistent asymmetrical pattern--heart and stomach to the left, liver and appendix to the right. But how does this happen? Biologists at Tufts University have produced the first evidence that a class of proteins that make up a cell's skeleton -- tubulin proteins -- drives asymmetrical patterning across a broad spectrum of species, including plants, nematode...

Looking For The Origin Of Muscles

Nature: Central components of muscles of higher animals much older than assumed A characteristic feature of most animals is their ability to move quickly with the help of their musculature. Animals that can move are able to flee, hunt for prey, travel long distances or conquer new habitats. The evolution of muscles was thus a fundamental step during animal evolution. While the structure and function of muscles, especially of vertebrates, have been intensively studied, the evolutionary...

SOUTH PLAINFIELD, N.J., June 27, 2012 /PRNewswire/ -- PTC Therapeutics, Inc. (PTC) today announced the initiation of an open-label study in the European Union, Israel, Australia and Canada for patients with nonsense mutation Duchenne/Becker muscular dystrophy (nmDBMD) who received ataluren in a prior, PTC-sponsored clinical study. The primary objective of this study is to gain further information on the long-term safety and tolerability of ataluren, an investigational new drug. PTC launched a...

An actin-ratchet tightens the contractile ring that severs budding daughter cells from their yeast mothers During the final stage of cell division, a short-lived contractile ring constricts the cellular membrane and eventually separates the dividing cell in two. Although this "molecular muscle's" composition, mainly actin and myosin, is similar to its skeletal counterpart, the force-producing mechanism is fundamentally different, report researchers at the Stowers Institute for Medical...

High-powered microscopes reveal workings of the cell -- results could impact treatment of Down syndrome, lissencephaly (a brain formation disorder) or cancer Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell — and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process. The findings by the international team led by...
