KIT computer models explain how ion channels in cell membranes react to light / light switch for nerve cells as a sensitive tool of research Networked nerve cells are the control center of organisms. In a nematode, 300 nerve cells are sufficient to initiate complex behavior. To understand the properties of the networks, re-searchers switch cells on and off with light and observe the resulting behavior of the organism. In the Science journal, sci-entists now present a protein that...

Researchers from the University of Southampton, in collaboration with researchers at the University of Quebec at Montreal, have developed a new microsystem for more efficient testing of pharmaceutical drugs to treat diseases such as cystic fibrosis, MG (myasthenia gravis) and epilepsy. A large percentage of pharmaceutical drugs target ion channels, which are proteins found in a cell's membrane, that play a pivotal role in these serious disorders and that are used to test the effectiveness...

While great strides have been achieved in cancer treatment, scientists are looking for the new targets and next generation of therapeutics to stop this second leading cause of death nationwide. A new platform for drug discovery has been developed through a collaborative effort linking chemists at NYU and pharmacologists at USC. In a study appearing in Proceedings of the National Academy of Sciences, the research groups of Paramjit Arora, a professor in NYU's Department of Chemistry, and...

Water Molecules Control Long Post-activation Recovery Period Of Potassium Channels
2013-07-29 08:51:57

University of Chicago Medical Center Just 12 molecules of water cause the long post-activation recovery period required by potassium ion channels before they can function again. Using molecular simulations that modeled a potassium channel and its immediate cellular environment, atom for atom, University of Chicago scientists have revealed this new mechanism in the function of a nearly universal biological structure, with implications ranging from fundamental biology to the design of...

UConn researchers shed new light on how cellular transport systems harness energy to perform their work inside the cell Using highly sensitive fluorescent probes, a team of scientists from the University of Connecticut has captured the never-before-seen structural dynamics of an important protein channel inside the cell's primary power plant – the mitochondrion. The UConn team's study found that the channel complex - known as the translocase of the inner mitochondrial...

Cancer Research In Space: Microgravity Could Be The Key
2013-06-25 13:19:29

Lee Rannals for redOrbit.com – Your Universe Online The International Space Station (ISS) has been helping provide cancer biologists a laboratory 220 miles above the surface of the Earth. Although it may seem a little odd, NASA says the orbiting laboratory acts as a great place to study cancer, along with other diseases. Cells in the human body normally grow within support structures made up of proteins and carbohydrates in three-dimensional shape. In a laboratory setting, however,...

“Outsourced Ion Channel Testing Trends 2013” is the new market research report added to ReportsnReports.com store. Dallas, Texas (PRWEB) May 03, 2013 This market report summarizes the results of global web-based benchmarking survey on outsourced ion channel testing carried out in April 2013. The full report provides the data, details of the breakdown of the responses for each question, its segmentation and the estimates for the future (2015). It also highlights some interesting...

Retinoic Acid Gradient Observed For The First Time In A Zebrafish Embryo
2013-04-08 13:31:35

RIKEN In a ground-breaking study, researchers from the RIKEN Brain Science Institute in Japan report a new technique that allows them to visualize the distribution of retinoic acid in a live zebrafish embryo, in real-time. This technique enabled them to observe two concentration gradients going in opposing directions along the head-to-tail axis of the embryo, thus providing long-awaited evidence that retinoic acid is a morphogen. The report, published today in the journal Nature, puts...

Hearing Mechanism Compared To Car Battery
2013-01-08 03:42:16

redOrbit Staff & Wire Reports - Your Universe Online One of the mechanisms involved in human hearing is similar to the operation of a car battery, according to a new study by researchers at the University of Iowa (UI). The scientists conducted their study using fruit flies, whose hearing mechanisms resemble that of humans. Specifically, the flies´ auditory system contains a protein that functions as a sodium/potassium pump, and is highly expressed in a specialized support...

Birth-defect Mystery Solved By BYU Biochemistry Professor And Students
2012-09-12 12:20:17

The cellular cause of birth defects like cleft palates, missing teeth and problems with fingers and toes has been a tricky puzzle for scientists. Now Professor Emily Bates and her biochemistry students at Brigham Young University have placed an important piece of the developmental puzzle. They studied an ion channel that regulates the electrical charge of a cell. In a new study published by the journal Development, they show that blocking this channel disrupts the work of a protein that is...
