NIAID begins clinical trial of West Nile virus vaccine

...the vaccine is injected into the muscle, the inner machinery of the muscle cells "reads" the DNA and converts it into two WNV proteins. Recognizing that the proteins are foreign, the muscle cells display them on their surface to alert the body's immune system--both helper T cells, which spur the production of ...

Novel gene-silencing nanoparticles shown to inhibit Ewing's sarcoma

...coma tumors. Once inside these cells, the genetic machinery of the tumor cells are effectively silenced or shut down, preventing further growth. "This is the first study to show that systemic administration of siRNA can inhibit disseminated tumor growth," said Siwen Hu, a postdoctoral fellow at Children's Ho...

Shutting down the HIV assembly line

... immunodeficiency virus hijacks that cell's normal machinery to produce carbon copies of itself. New HIV particles roll off the cellular assembly lines, burst like bubbles out of the cell, and float off to invade other cellular factories. Vanderbilt University Medical Center investigators have now identified a...

Gene Therapy Cures Inherited Liver Disease In Rats

...erm effect. It does not become part of the genetic machinery of the cell and poses no risk of causing cancer, said Lee. "This approach would be applicable to many diseases where you are trying to put something back, targeting the liver," he said. He is hesitant to predict when the treatment can be tried in h...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...functionally important proteins are assembled into machinery from one species to another is also, to a certain degree, conserved," said Ideker. "The circuitry is not exactly the same. In fact, there are striking differences that warrant more investigation." The team included Roded Sharan, a computer scientist...

An HIV Protein Plays a Surprising Role in Gene Activation

...e HIV have evolved myriad ways of redirecting that machinery to their own benefit. Humans and other eukaryotes have three types of RNA polymerases, each charged with transcribing different types of genetic elements. RNA polymerase II transcribes protein-coding genes. RNA polymerases join with so-called genera...
