Duke scientists discover new small-molecule drugs to treat chronic pain

A research team at Duke University has discovered a potential new class of small-molecule drugs that simultaneously block two sought-after targets in the treatment of pain.

Study finds that TPC2 protein regulates melanin production

A year and a half ago, researchers at Brown University found a molecular gas pedal for melanin production. Now they've found a brake. For scientists, the finding deepens not only the basic understanding of how eyes, skin and hair gain color, but also what perhaps can be done in disorders, such as albinism, when that doesn't happen.

TSRI scientists discover new method for harnessing venoms for therapeutic use

There are lessons to be learned from venoms. Scorpions, snakes, snails, frogs and other creatures are thought to produce tens or even hundreds of millions of distinct venoms. These venoms have been honed to strike specific targets in the body.

Researchers partially restore lost function of isolated cystic fibrosis lung cells

In experiments with isolated cystic fibrosis lung cells, University of Alabama at Birmingham researchers and colleagues from two other institutions have partially restored the lost function of those cells.

New molecule has potential to prolong life of cystic fibrosis patients

Scientists at Queen's University Belfast have discovered a new molecule which has the potential to prolong the life of individuals with cystic fibrosis (CF).

Controlling heart cells using a laser: an interview with Prof. Konstantin Agladze

We control their electrical activity. Cardiac cells are capable of producing and transmitting electric signals through changes in a cell membrane potential.

Snapshots of NMDA receptor activation may help in novel drug design

Structural biologists at Cold Spring Harbor Laboratory and Janelia Research Campus/HHMI, have obtained snapshots of the activation of an important type of brain-cell receptor. Dysfunction of the receptor has been implicated in a range of neurological illnesses, including Alzheimer's disease, Parkinson's disease, depression, seizure, schizophrenia, autism, and injuries related to stroke.

Newly identified molecular pathway could lead to new treatments for reflux, incontinence disorders

Researchers at UMass Medical School have identified a new molecular pathway critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system.

Scientists find way to control behaviour of cardiomyocytes using laser radiation

Scientists from MIPT's Laboratory of the Biophysics of Excitable Systems have discovered how to control the behaviour of heart muscle cells (cardiomyocytes) using laser radiation; this study will help scientists to better understand the mechanisms of the heart and could ultimately provide a method of treating arrhythmia. The paper has been published in the journal PLOS ONE.

Scientists identify key pathway that regulates 'switch' between wakefulness and sleep

Falling asleep and waking up are key transitions in everyone's day. Millions of people have trouble with these transitions - they find it hard to fall asleep or stay asleep at night, and hard to stay awake during the day. Despite decades of research, how these transitions work - the neurobiological mechanics of our circadian rhythm - has remained largely a mystery to brain scientists.

CRPS rank higher on pain scales than childbirth, cancer, amputation

Imagine pain in an arm or leg so intense that the sufferer would rather undergo an amputation than put up with it any longer. For those with complex regional pain syndrome (CRPS), this is not just a hypothetical nightmare—it is reality.

Neurons in hypothalamus help maintain blood glucose levels, study finds

To learn what different cells do, scientists switch them on and off and observe what the effects are. There are many methods that do this, but they all have problems: too invasive, or too slow, or not precise enough. Now, a new method to control the activity of neurons in mice, devised by scientists at Rockefeller University and Rensselaer Polytechnic Institute, avoids these downfalls by using magnetic forces to remotely control the flow of ions into specifically targeted cells.

Johns Hopkins scientists develop antibody to curb lung tumor cell growth, breast cancer metastasis

Johns Hopkins scientists report they have developed an antibody against a specific cellular gateway that suppresses lung tumor cell growth and breast cancer metastasis in transplanted tumor experiments in mice, according to a new study published in the February issue of Nature Communications.

Study could lead to potential new therapeutic target with fewer side effects for hypertension

A team of Vermont investigators has been issued a patent for their discovery of a molecule that rescues damaged blood vessels, yet preserves healthy vessels and could serve as a springboard for a new pharmaceutical therapy with fewer side effects for hypertension - a major risk factor for cardiovascular and kidney disease that effects roughly one in three people in the U.S.

Researchers identify new mutation responsible for spinocerebellar ataxia

Using the genetic information of two different families with three generations of disease, researchers have identified a new mutation responsible for a degenerative and ultimately fatal movement disorder. Through induced pluripotent stem cell techniques, researchers also grew neurons from one patient in the laboratory to be used in future experiments.

Researchers identify potential drug target in skin for itchy feeling

No matter the trigger -- bug bites, a medication side-effect or an itchy wound -- the urge to scratch can be a real pain. Researchers at the Duke University Medical Center have identified a potential drug target in the skin for that itchy feeling.

Inhibition of mitochondrial calcium uptake specifically toxic to cancer cells

Inhibiting the transfer of calcium ions into the cell's powerhouse is specifically toxic to cancer cells, according to an article published this week in Cell Reports by researchers from the Perelman School of Medicine at the University of Pennsylvania.
