A newly defined biochemical pathway in plants may provide the scientific tools to design plants that will yield larger quantities of alternative transportation fuels than currently can be produced, according to Purdue University researchers. The pathway moves materials that determine cell shape and size through a system of signaling proteins, said Dan Szymanski, a plant geneticist and cellular biologist. By learning more about the growth and development process, it may be possible to engineer...

PROVIDENCE, R.I. -- How life takes shape is a mystery. Butterfly or baby, cells organize themselves into tissues, tissues form organs, organs become organisms. Over and over, patterns emerge in all living creatures. Spiders get eight legs. Leopards get spots. Every nautilus is encased in an elegant spiral shell. This phenomenon of pattern formation is critical in developmental biology. But the forces that govern it are far from clear. Alan Turing, father of modern computer science,...

UA's nanotechnology research group is using proteins from living cells to "grow" wires on microchips. Their work promises to revolutionize the way microchips are made by combining biology and electronics "” leading to smaller, faster and more efficient circuits for cell phones, computers, MP3 players and a thousand other microelectronic devices. But that's only one of the benefits of this research. The work holds promise in several areas, such as improving testing methods for anticancer...

Researchers at the Albert Einstein College of Medicine and the German Cancer Research Institute have shown how protein synthesis is targeted to certain regions of a cell--a process crucial for the cellular motility that governs nerve growth, wound healing and cancer metastasis. Their study appears in the November 24 issue of the journal Nature. Led by Drs. Robert Singer and Dr Stefan Huettelmaier, the research team focused on migrating fibroblast cells important in wound healing. To move...

A new study provides important insight into the mechanisms of a muscle wasting disorder that interferes with treatment for cancer and has a negative impact on patient survival. The research, published in the November issue of Cancer Cell, describes an unexpected link between muscular dystrophy and muscle wasting associated with cancer, and suggests a potential strategy for development of therapies to combat cancer-associated muscle wasting. Muscle wasting, or cachexia, is a severe and...

Biological cells are mechanically stable because they contain actin filaments and microtubules that form networks and bundles. These filament architectures are determined and controlled by crosslinking proteins, which have two sticky ends that bind to different filaments. In order to understand the underlying forces and to optimise the mechanical properties of these architectures, one must study biomimetic model systems that are solely composed of filaments and crosslinking proteins. One...

Santa Barbara, Calif.) "“ Materials scientists working with biologists at the University of California, Santa Barbara have developed "smart" bio-nanotubes "” with open or closed ends "” that could be developed for drug or gene delivery applications. The nanotubes are "smart" because in the future they could be designed to encapsulate and then open up to deliver a drug or gene in a particular location in the body. The scientists found that by manipulating the electrical...

ANN ARBOR, Mich. "“ A common chemical used in the manufacturing and pharmaceutical industries can repair damage to cardiac muscle cell membranes and prevent heart failure in mice with the genetic mutation that causes Duchenne muscular dystrophy, according to scientists at the University of Michigan Medical School. The mutation in the dystrophin gene causes the progressive deterioration of skeletal muscles seen in people with MD. But the mutation affects cardiac muscle, too. Many people...

Microtubules need a helping hand to find chromosomes in dividing egg cells, scientists have discovered. Although it was generally accepted that microtubules act alone as the cellular ropes to pull chromosomes into place, a new study by researchers at the European Molecular Biology Laboratory (EMBL) shows that this is not the case. They found that in large cells such as animal eggs, something else is needed to move the chromosomes into the correct location - fibres of the cytoskeletal molecule...

BERKELEY, CA "“ Microtubules are active protein polymers critical to the structure and function of cells and the process of cell division. In a living cell their growing ends constantly elongate and retreat in a thrashing frenzy of polymerization and depolymerization, like the writhing snakes of Medusa's hair. Known prosaically as "dynamic instability," this ongoing rapid growth and shrinkage is key to the diverse workings of microtubules in the cell.  For the first time,...
