Model-independent way to study ion channel gating

Two studies in The Journal of General Physiology (JGP) help pave the way for a "shortcut" model-free approach to studying activation of "polymodal" ion channels-channels that open in response to multiple stimuli. Transmembrane ion channels respond to various physiological stimuli to regulate numerous cellular functions. Different classes of channels respond to different types of stimuli; some channels, for instance, respond to changes in membrane potential whereas others are activated by ligand binding.

Ion channel acts as powerful ‘brake’ after epileptic seizures

Given that epilepsy impacts more than 2 million Americans, there is a pressing need for new therapies to prevent this disabling neurological disorder. New findings from the neuroscience laboratory of Mark S. Shapiro, Ph.D., at The University of Texas Health Science Center at San Antonio, published Dec. 20 in the high-impact scientific journal, Neuron, may provide hope.

Scientists uncover molecular basis of gentle touch

Stroke the soft body of a newborn fruit fly larva ever-so-gently with a freshly plucked eyelash, and it will respond to the tickle by altering its movement-an observation that has helped scientists at the University of California, San Francisco (UCSF) uncover the molecular basis of gentle touch, one of the most fundamental but least well understood of our senses.

Bisphenol A blocks calcium channels in cell membranes

Bisphenol A, a substance found in many synthetic products, is considered to be harmful, particularly, for fetuses and babies. Researchers from the University of Bonn have now shown in experiments on cells from human and mouse tissue that this environmental chemical blocks calcium channels in cell membranes. Similar effects are elicited by drugs used to treat high blood pressure and cardiac arrhythmia. The results are now presented in the journal "Molecular Pharmacology."

New paper describes MCUR1 protein and its function

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

Study shows how MCUR1 protein helps regulate movement of calcium into mitochondria

A team of scientists from Temple University School of Medicine and the University of Pennsylvania has moved another step closer to solving a decades-long mystery of how the all-important flow of calcium into the cell's power source, the mitochondria, is controlled.

Obesity and oxidative stress: an interview with Dr Elizabeth New

Even though oxygen is essential for us to live, it can react with other compounds in the body to produce molecules called free radicals, which are highly reactive and damaging.

Electrophysiology: an interview with Dr Kaylene Young

Bioelectricity is an essential part of our make-up. All cells in our body communicate by electrical activity. If an electrical charge is applied to one of our muscles it will interpret that electrical activity as a signal telling it to contract.
