Live vaccines more effective against horse herpes virus
...he same symptoms from the initial infection can be reactivated
by stress later in life. Osterrieder will present his new findings on vaccine effectiveness, involving a limited study of 15 horses, at a luncheon meeting with other veterinarians and specialists at the annual American College of Veterinary Internal...
Researchers discover mechanism for multiplying adult stem cells
...e what happens in laboratory mice when the gene is reactivated
in adult tissue where it has long been dormant. Hochedlinger found that when he switched the gene on, the mice immediately formed tumors in the gut and in the skin where the gene was active. When he switched the gene off, the tumors subsided, demonst...
Sleeping beauty plays a significant role in identifying cancer genes
...h and made the genes jump again. This research had reactivated
the jumping genes from millions of years of evolutionary sleep; hence the name Sleeping Beauty. In the two current research studies, specially designed Sleeping Beauty transposons were introduced into mouse DNA and made to jump around in the nucleus...

in cancer cells. The research is the latest in a series of studies conducted at NYU's Center for Comparative Functional Genomics in collaboration with researchers at Harvard and Yale Universities, which set the stage for these most recent findings. ...

(by stress of many kinds), HSV-1 proteins are synthesized and new infectious virus particles are formed. These virus particles migrate along the neuronal axons to the epithelial cells of the skin. Viral growth in the skin, or other mucous membranes w...
