Latest Actin Stories
A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al. The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14).
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 â€” even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes.
Cells rely on tiny molecular motors to deliver cargo, such as mRNA and organelles, within the cell. The critical nature of this transport system is evidenced by the fact that disruption of motors by genetic defects leads to fatal diseases in humans.
Understanding how neurons migrate to their proper place during brain development will offer insights into how malfunctions in the machinery cause epilepsy and mental retardationMEMPHIS, Tenn., July 15 /PRNewswire-USNewswire/ -- The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St.
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.
Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories.
Notch signaling helps determine the fate of a number of different cell types in a variety of organisms, including humans.
DNA might be the blueprint for living things, but proteins are the builders. Researchers trying to understand how and which proteins work together have developed a new crosslinking tool that is small and unobtrusive enough to use in live cells.
During desperate times, such as fasting, or muscle wasting that afflicts cancer or AIDS patients, the body cannibalizes itself, atrophying and breaking down skeletal muscle proteins to liberate amino acids.
Advanced Control Systems Enable Robotic Oil and Natural Gas Drilling CAMBRIDGE, Mass., May 27 /PRNewswire/ -- Seabed Rig AS has licensed technology and contracted with Energid Technologies Corporation to create a robot control system for its next-generation automated drilling and exploration platforms. Seabed Rig AS is developing a new autonomous drilling rig that operates in ultra deep water and arctic environments.
