50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

... brain, heart and skeletal muscles "fire," sending out nervous impulses that become thoughts, heartbeats ...ch as potassium, sodium and calcium to flow in and out and so are key regulators of many fundamental processes in biology. "Ions are the currency of the c...

Stem cells from brain transformed to produce insulin at Stanford

...insulin was exciting. Kim's next step was to find out if the cells could perform the same feat in a mouse. The group transplanted the cells into a cavity in the kidney where other types of insulin-producing cells have been found to survive. When the blood sugar went up in these mice, the cells once agai...

Stopping smallpox in its tracks: A new anti-viral approach

...lberg from the National Institutes of Health point out that this approach "may serve to turn the tables on the virus by interfering with the very pathways that are required for viral replication and extrusion." This study demonstrates, for the first time, that chemical inhibition of host cell signaling ...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

Key mechanism in genetic inheritance during cell division identified

...d controls the transportation of substances in and out of a cell. During cell division (mitosis), the microtubule fibers disassemble and reform into spindles across which duplicate sets of chromosomes line up. During this phase, it is critical that the spindles maintain their structural integrity so that...

Multi-purpose protein regulates new protein synthesis and immune cell development

...'s only one IRE1 gene and one protein that carries out a unique biochemical reaction. This makes IRE1 a perfect target for pharmacological intervention for B cell-driven autoimmune diseases, like myasthenia gravis or systemic lupus erythematosus." Results from the study will be published in the Feb. 1 i...

Computational Method Speeds Mapping of Cell Signaling Networks

...mpt activated T-cells to multiply rapidly and send out molecular "distress signals" that attract other immune system molecules to battle the infection. Components in the pathway are chemically altered during the signaling. Such alterations occur only at points of active signaling in the network. The res...

Researchers rein in regulatory RNAs

...denori Kiyosawa, the lead author on the paper, set out to confirm the presence of SATs in a variety of mouse tissue types and cell cultures, as well as to identify common characteristics of these unique transcripts. Employing a custom-made microarray chip designed to detect strand-specific expression of...

Birds brains reveal source of songs

...motor pathway that is producing a song, jarring it out of the routine and making it sing something new," Fee says. Then another, still unexplained, pathway compares that variation to the bird's memory of the father's song. Gradually, the bird gets it right more often and eventually sings only the songs o...

"The evidence in favor of the prion hypothesis was strong, but the final proof was still missing. Now we have supplied this proof." Soto emph...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

.... Successful testing of this idea has been carried out by three vessels fishing for tuna in Pacific waters. In initial testing, 42 percent more bigeye tuna were caught using Beverly's new weighted, deep-set gear. An innovative combination of glowing ropes and stiffer nets--the results of collaboration a...
