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.
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, suggested that the basis for pattern formation was chemical.
UA's nanotechnology research group is using proteins from living cells to "grow" wires on microchips.
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.
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.
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...
Materials scientists working with biologists at the University of California, Santa Barbara have developed "smart" bio-nanotubes â€” with open or closed ends â€” that could be developed for drug or gene delivery applications.
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.
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.
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.
