Research out this week helps us understand basics of how neurons communicate

...um cannot freely enter cells, and must wait for an opening of a molecular gate, which is called a calcium channel. "In this study we removed a specific part of the calcium channel molecule called the 'synaptic protein interaction site' and put this mutant calcium channel back into cells," Dr. Harkins said. "...

Channel protein converts vibrations to electrical signal

...e which is as much as 1,000 times faster than the opening of similar channels in the eye in response to light indicated to scientists that the channel must respond directly to the mechanical stimulus, rather than relying on a signal from another molecule. The speed of the response was determined more than ...

Clues to improving TB treatment

...Oc. The presence of HexOc alters EthR's structure, opening up a wider gap between two key DNA recognition areas on the protein. The wider gap disrupts EthR's ability to bind to DNA and limit the production of the EthA enzyme, the researchers found. The next step for Baulard and colleagues was to show ...

Sandbagging cancer in the bloodstream

Once tumor cells leave their primary tumor, they enter the blood stream and ultimately must find an exit strategy in order to set up new "satellite" lesions...

Stress impairs thinking via mania-linked enzyme

... The enzyme then travels out to the cell membrane, opening ion channels that heighten the cell's excitability, and stoking protein machinery that propels neurotransmitters into the synapse. PKC also moves into the cell's nucleus, where it turns-on genes. To tease out PKCs role, the researchers selectively ...

"Often, these aquifers are contaminated. Sources of contamination include runoff from paved surfaces or because a good portion o...

Researchers discover transport molecule that allows boron into cells

...on transporters are embedded in the cell membrane, opening and closing like gates to let charged ions and molecules enter and leave the cell. The movement of these molecules affects numerous essential cellular functions. Like other nutrients, cells must transport boron across the membrane to control its c...

New gene target found for common brain tumors in children

...of one of the most common childhood brain cancers, opening the door to tailored therapies that block the gene's tumor-promoting ability. The gene, called Notch2, whose pathway is known to be an important factor in regulating brain stem-cell growth and survival, has been studied in fruit flies for almost a ce...

2004 IUCN Red List of Threatened Species reveals 15,589 species at risk of extinction

Halting the growing extinction crisis will be a major focus of the 3,500 delegates attending the world's largest conservation gathering. "This sobering new report should serve as a wake-up call to take imm...

How receptors govern inflammatory pain
