University of Illinois Researchers have tried for decades to understand the undulations and gyrations that allow transport proteins to shuttle molecules from one side of a cell membrane to the other. Now scientists report that they have found a way to penetrate the mystery. They have worked out every step in the molecular dance that enables one such transporter to do its job. The new findings, reported in the Proceedings of the National Academy of Sciences, will help scientists figure...

For the first time, researchers at Karolinska Institutet in Sweden have managed to obtain detailed images of the way in which the transport protein GLUT transports sugars into cells. Since tumors are highly dependent on the transportation of nutrients in order to be able to grow rapidly, the researchers are hoping that the study published in the scientific magazine Nature Structural & Molecular Biology will form the basis for new strategies to fight cancer cells. In order to be able to...

A research team led by Edward Yu of Iowa State University and the Ames Laboratory has identified and described two parts of the three-part system that pumps toxins from bacteria and allows them to resist antibiotics. The discoveries are published in the Feb. 24 issue of the journal Nature. The paper describes the co-crystal structure of two parts of the three-part efflux pump that recognizes and removes heavy metal toxins from bacteria. A research team led by Yu "“ an Iowa State...

Scientists at IRB Barcelona resolve a three-dimensional structure required for the function of some vital cell transporters which communicate cells with the external environment. This finding will contribute to understanding some of the functional disruptions caused by human diseases. Researchers at IRB Barcelona have completed the 3D structural sequence adopted by several essential proteins in the exchange of substances between the extra and intracellular milieu. This finding provides a...

A research team led by Edward Yu of Iowa State University and the Ames Laboratory has discovered the crystal structures of pumps that remove heavy metal toxins from bacteria, making them resistant to antibiotics. The findings are published in the Sept. 23 issue of the journal Nature. Yu - an Iowa State associate professor of chemistry, of physics and astronomy, of biochemistry, biophysics and molecular biology and an associate of the U.S. Department of Energy's Ames Laboratory - said the...

The blood-brain barrier (BBB) remains a major obstacle to the successful delivery of drugs to treat central nervous system (CNS) disorders, reports Genetic Engineering and Biotechnology News (GEN). Researchers are exploring a variety of approaches to preserve the ability of the BBB to block harmful and toxic substances from entering the brain and to permit the passage of effective medicines for the treatment of CNS diseases, according to the February 1 issue of GEN. "The blood-brain barrier...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
