DNA Recombination and Repair—A New Twist to RecA Function

...nclude myosin and dynein, proteins that use ATP to ferry intracellular cargo along fibers made of actin or tubulin proteins. The ATP-dependent assembly of actin or tubulin fibers itself can work as a motor: for instance, the march of white blood cells toward pathogens is powered by the growth of actin fila...

UW scientists report a new method to speed bird flu vaccine production

...reducing the number of plasmid vectors required to ferry viral genes into the monkey kidney cells used to produce the virus particles to make vaccines."Compared to other types of cells, which are not approved for vaccine production, it is not always easy to introduce plasmids into the monkey kidney cells, ...

Image of myosin-actin interaction revealed in cover story of Molecular Cell

...khorse of the myosin protein family. It exists to ferry a cargo of proteins needed in a specific place at a specific time. Fueled by hydrolysis -- the process of converting the molecule adenosine triphosphate (ATP) into energy -- myosin V travels in one direction using actin as a track to deliver its payl...

UW scientists unravel critical genetic puzzle for flu virus replication

...g the possibility of using strains of influenza to ferry genes from one virus to another to speed and optimize vaccine production. More efficient methods of vaccine production will be critical should a global outbreak such as the "Spanish " flu pandemic of 1918 recur. That pandemic killed an estimated 30-5...

Nano-particles effective in killing cancer with one-two punch of chemotherapeutics

...es take advantage of the polymersome properties to ferry their drug combination to the tumor. The large polymers making up the shell allow paclitaxel, which is water-insoluble, to embed within the shell. Doxorubicin, which is water-soluble, stays within the interior of the polymersome until it degrades. ...

Cell wall of pneumonia bacteria can cause brain and heart damage

...e have learned how to exploit PAFr and use it as a ferry to cross the endothelium of the blood vessels and escape from the bloodstream," Tuomanen said. "From there they enter the cardiomyocytes or neurons in the brain by binding to PAFr on those cells as well." The investigators used laboratory culture ...

Novel laboratory technique nudges genes into activity

...d "copied" to strands of messenger RNA, which then ferry the plans to protein-making "factories" in the cell. In its experiments, the UT Southwestern team used strands of RNA that were tailor-made to complement the DNA sequence of a specific gene in isolated breast cancer cells. Once the RNA was introd...

Jefferson scientists find rabies-based vaccine could be effective against HIV

...a have used a drastically weakened rabies virus to ferry HIV-related proteins into animals, in essence, vaccinating them against an AIDS-like disease. The early evidence shows that the vaccine ?which doesn’t protect against infection ?prevents development of disease. Reporting April 1, 2007 in the Journa...

Brain's white matter -- More 'talkative' than once thought

...e mammalian brain’s white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do. The discovery in mouse cells, outlined in the cover story of the March issue of Nature Neuroscience, shows that brain cells “talk?with each ot...
