Synthetic peptide targets latent papilloma virus infections

...he base of the skin that can turn into many of the various types of cells that make up the skin. As these cells divide and differentiate into skin cells, the viruses hitch a ride on the cells' chromosomes but do not become part of the chromosomes, as do other known pathogens, such as HIV in blood cells. Th...

A genetic 'gang of 4' drives spread of breast cancer

...ng." To test this idea, the researchers silenced various combinations of the four genes in human breast cancer cells that had metastasized to the lung, and then tested these cells in mice. To silence the four genes, the scientists used a technique called RNA interference, in which RNA molecules are tailore...
