...e beneficial reaction to continue. In addition, it interrupted the feedback loop that stoked calpain activation. "This is potentially a treatment for any conditions that involve this kind of excitotoxicity," Baudry said, and especially, he added, for the "window of opportunity" in the few hours after a stroke...

Protein splicing upsets the DNA colinearity paradigm

... colinearity of DNA and protein sequences was only interrupted by RNA splicing," says LICR's Dr. Benoit Van den Eynde, the study's senior author. "This new study shows that protein splicing also occurs, and may even result in protein fragments, or peptides, being spliced together in the order opposite to that wh...

'Trojan Horse' agent halts bone metastasis in mice

... but what they did not know is whether the protein interrupted bone maintenance or promoted growth of blood vessels to feed the neophyte cancer, Rosenblum said To find out, Rosenblum designed an experiment with VEGF121/rGel, an agent he and his colleagues began to develop several years ago. They created the ...

MIT sheds light on how tumor cells form

...they removed either protein from a cell or if they interrupted the way the proteins work together, the cell would become aneuploid. In other words, the checkpoint proteins need to sense that the APC and EB1 proteins both are present for normal cell division to take place. "This is important because it is the fi...

Gene variation increases SIDS risk in African Americans

...abies sleeping on their bellies had more spells of interrupted breathing or apnea. One of the immediate consequences of apnea is a slight increase in acid levels inside oxygen-hungry muscle cells.

Researchers reverse juvenile diabetes in animal model

...s over the course of several weeks. The injections interrupted the T cell and beta cell interaction, allowing the beta cells in the pancreas to regenerate. This enabled the pancreas of the mice to begin producing insulin again," said Dr. Trucco, who also is the Hillman Professor of Pediatric Immunology at Childr...

Synthetic Protein Eases Arthritis Symptoms in Mice

...functioning correctly. In ALPS, the signal pathway interrupted by PLAD leads to disease symptoms. But, the scientists reasoned, PLAD might also be able to block a related cell surface receptor ?one involved in passing signals that lead to inflammation. In theory, inhibiting this pathway might benefit people with...

Sperm trading can resolve hermaphrodite mating conflicts

...ea slugs that mated with such a "cheating" partner interrupted sexual intercourse significantly sooner than did control pairs. This supports the concept of sperm trading, where mates negotiate mating roles in order to balance sexual interactions. ...
