It is helpful "” even life-saving "” to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that's easy to read is a challenge. Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change. The study was conducted by professor Daniel Hammer and graduate students Neha Kamat and Laurel Moses...

As the gatekeepers of ion flow through cell membranes, ion channels are of key interest in numerous cellular processes. Now, a new study describes an innovative new computational model that realistically simulates the complex conditions found in biological systems and allows for a more accurate look at ion channel function at the level of individual atoms. The research, published by Cell Press in the August 17th issue of the Biophysical Journal, provides a remarkably detailed look at the...

The research group of Professor Pekka Lappalainen at the Institute of Biotechnology, University of Helsinki, has identified a previously unknown mechanism which modifies the structure of plasma membranes in intestinal epithelial cells. Unlike other proteins with a similar function, the new protein "“ named 'Pinkbar' by the researchers - creates planar membrane sheets. Further research investigates the potential connection of this protein with various intestinal disorders. The study was...

Plant receptors use different signalling method than do animal receptors Every living plant cell and animal cell is surrounded by a membrane. These cellular membranes contain receptor molecules that serve as the cell's eyes and ears, and help it communicate with other cells and with the outside world. The receptor molecules accomplish three basic things in the communication process: 1) recognize an outside signal, 2) transport that signal across the cell's membrane and 3) initiate the reading...

The mechanisms by which obesity leads towards metabolic co-morbidities, such as diabetes mellitus, are poorly understood and of great public health interest. A study led by Matej OreÃ…¡ič from VTT Technical Research Centre of Finland suggests that adaptation of fat cell membranes to obesity may play a key role in the early stages of inflammatory disorders. Millions of adults are diagnosed as obese each year, worldwide. Many of these people suffer...

(Ivanhoe Newswire)-- Millions of adults are diagnosed with obesity each year, but how do fat cell membranes adapt to this high body mass index? A study led by Matej Oresic, from VTT Technical Research Center of Finland, suggests that adaptation of fat cell membranes to obesity may play a major role in early stages of inflammatory disorders. Many of those diagnosed with obesity suffer from a disorder known as metabolic syndrome which includes symptoms such as hypertension and elevated blood...

Max Planck scientists decipher important mechanisms of bacterial cell wall synthesis Almost all bacteria owe their structure to an outer cell wall that interacts closely with the supporting MreB protein inside the cell. As scientists at the Max Planck Institute for Biochemistry and at the French INRA now show, MreB molecules assemble into larger units, but not - as previously believed "“ into continuous helical structures. The circular movement of these units along the inside of the...

Blood clotting is a complicated business, particularly for those trying to understand how the body responds to injury. In a new study, researchers report that they are the first to describe in atomic detail a chemical interaction that is vital to blood clotting. This interaction "“ between a clotting factor and a cell membrane "“ has baffled scientists for decades. The study appears online in the Journal of Biological Chemistry. "For decades, people have known that blood-clotting...

In two new studies, researchers provide the first detailed view of the elaborate chemical and mechanical interactions that allow the ribosome "“ the cell's protein-building machinery "“ to insert a growing protein into the cellular membrane. The first study, in Nature Structural and Molecular Biology, gives an atom-by-atom snapshot of a pivotal stage in the insertion process: the moment just after the ribosome docks to a channel in the membrane and the newly forming protein winds...
