Calcium channels control coronary artery relaxation

...nces across the cell membrane, while the T-channel responds to a weaker "depolarization," he said. Campbell and his colleagues first became interested in exploring the T-channel because research by other scientists hinted that it might be involved in the fusion of muscle cells, or myoblasts, to one another du...

Proteins may help identify patients who will respond better to treatments in certain cancers

...h), which are known to affect the way that a tumor responds to radiotherapy. "We are using new strategies for data analysis to exploit the potential of molecular markers," said Francesca Buffa, PhD, of the Gray Cancer Institute in London. "We hope that by tailoring cancer therapy to the biological behavior ...

Mantis shrimp fluoresce to enhance signaling in the dim ocean depths

...ree visual pigments in color vision, each of which responds to light of a different color by sending signals to the brain, which recreates a richly colored world. Some stomatopods, however, have at least eight pigments sensitive to various visual wavelengths and three more sensitive to ultraviolet light. Plus...

Diet may improve cognition, slow aging, and help protect against cosmic radiation

...age-related increase in a protein (NF-kappaB) that responds to oxidative stress, a probable cause of brain aging. "Our findings fit into an emerging pattern of data from many laboratories that point to a buildup of oxidative damage as one of the key factors in brain aging," says Pilar Goyarzu, a doctoral stud...

NIH establishes Rare Diseases Clinical Research Network

...nd imaging facilities. The creation of the network responds to the Rare Disease Act of 2002, which directed NIH to support "regional centers of excellence for clinical research into, training in, and demonstration of diagnostic, prevention, control, and treatment methods for rare diseases." The term "rare (or...

Jefferies' research focuses on dendritic cells. A networ...

Retroviral protein triggers proliferation of immune cells

...uses adult T-cell leukemia/lymphoma, a cancer that responds poorly to treatment and that can cause death within six months of diagnosis. In others, it causes crippling and painful autoimmune-like disorders. Lairmore and a team of colleagues tested the function of p12 in both laboratory-grown lymphocytes know...

There is also a contribution from resident hepatic stem cells, about which little is known. Miguel Marcos and colleagues from Universidad ...

Scientists determine identity, cell locale and quantity of nearly all proteins in an organism

...tion, and at least one phase in which the organism responds to specialized stress conditions and produces spores - sort of like abandoning ship. The scientists expect that a significant proportion of the proteins they did not identify simply are not expressed in the normal growth phase that they studied. In a...

New protein provides clue to diabetes

...in sends a signal. It is the only transporter that responds exclusively to the presence of insulin. For the study, Bogan engineered GLUT4 proteins so that they contained two distinct fluorescent tags, and studied them in cultured fat cells. One tag glowed only when GLUT4 appeared at the cell surface. The ot...

What can the genomics revolution teach us about global change?

... how an organism whether a microbe or corn plant responds to its environment. These scientists hope to understand how global warming and increased carbon dioxide affect agriculture production. "There remains great uncertainty over how crops respond to interacting environmental factors and whether new varie...

Grant explains that the Deschutes River possesses several unique characteristics: It has the most constant streamflow of any river of its size in the United States and behaves like a large, spring-fed...

Protein is shown to aid cell's reading of genetic code

...ly cells and studied the activation of a gene that responds to heat shock by rapidly making large amounts of protein that helps the fly adjust to heat stress. The process of gene expression is the same throughout the animal kingdom, so the work applies as much to humans as to fruit flies, Lis notes. The rese...
