Could controlling cell-membrane fat play a key role in turning off disease? Researchers at the University of Illinois at Chicago think so, and a biosensor they've created that measures membrane lipid levels may open up new pathways to disease treatment. Wonhwa Cho, distinguished professor of chemistry, and his coworkers engineered a way to modify proteins to fluoresce and act as sensors for lipid levels. Their findings are reported in Nature Chemistry, online on Oct. 9. "Lipid...

Professor Rikard Blunck receives the Society of General Physiologists' Cranefield Award for his breakthrough Toxin proteins are genetically engineered into our food because they kill insects by perforating body cell walls, and Professor Rikard Blunck of the University of Montreal's Group for the study of membrane proteins (GÉPROM) has detected the molecular mechanism involved. In recognition of his breakthrough, he received the Traditional Paul F. Cranefield Award 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...

By mimicking the structure of the silk moth's antenna, University of Michigan researchers led the development of a better nanopore"”a tiny tunnel-shaped tool that could advance understanding of a class of neurodegenerative diseases that includes Alzheimer's. A paper on the work is newly published online in Nature Nanotechnology. This project is headed by Michael Mayer, an associate professor in the U-M departments of Biomedical Engineering and Chemical Engineering. Also collaborating...

Rapid turnover and remodelling of lipid membranes could help phytoplankton cope with nutrient scarcity in the open ocean. A team led by Patrick Martin of the National Oceanography Centre has shown that a species of planktonic marine alga can rapidly change the chemical composition of its cell membranes in response to changes in nutrient supply. The findings indicate that the process may be important for nutrient cycling and the population dynamics of phytoplankton in the open ocean. Tiny...

Nanopore array allows simultanous tests in search for new drugs Membrane-associated receptors, channels and transporters are among the most important drug targets for the pharmaceutical industry. The search for new drugs resembles looking for a needle in a haystack. Therefore new analytical techniques are required which facilitate the simultaneous screening of a large library of compounds across a variety of membrane proteins. However, this class of methods is still at the early stages of...

Researchers dispel the notion that membrane infrastructure is all water like... it can have bounce, too Mix two parts cornstarch and one part water. Swirl your fingers in it slowly and the mixture is a smoothly flowing liquid. Punch it quickly with your fist and you meet a rubbery solid -- so solid you can jump up and down on a vat of it. It turns out that cell membranes "“ or, more precisely the two-molecule-thick lipid sheets that form the structural basis of all cellular membranes --...

NEW YORK, Sept. 29 /PRNewswire-USNewswire/ -- The International Journal of Astrobiology, a peer reviewed scientific journal published by Cambridge University Press, has published "The Origin of the Vertebrate Skeleton," submitted by Synthetic Life Lab of New York City. It has been reprinted in Astrobiology Magazine, an official organ of NASA. The paper describes the origin of the human skeleton and the shapes of the component bones in sequential animations beginning with the fertilized...

Research published in the journal Genetics suggests that sertraline targets intracellular membranes of yeast cells that don't express the known therapeutic target, suggesting a secondary drug target or pathway A new discovery about selective serotonin reuptake inhibitors (SSRIs) suggests that these drugs, which are used to treat mental health disorders like depression and anxiety, have multiple effects on our cells. In a research report published in the August 2010 issue of GENETICS...

Bioprobes offer first intracellular measurements with a semiconductor deviceChemists and engineers at Harvard University have fashioned nanowires into a new type of V-shaped transistor small enough to be used for sensitive probing of the interior of cells.The new device, described this week in the journal Science, is smaller than many viruses and about one-hundredth the width of the probes now used to take cellular measurements, which can be nearly as large as the cells themselves. Its...
