Organisms employ a fascinating array of strategies to identify and restrain invasive pieces of foreign DNA, such as those introduced by viruses.
Small RNA-based nucleic acid drugs represent a promising new class of therapeutic agents for silencing abnormal or overactive disease-causing genes, and researchers have discovered new mechanisms by which RNA drugs can control gene activity.
Small, mobile sequences of DNA left over from viruses, called transposons or "jumping genes" because of their ability to move around the genome, pose a significant threat to the genetic integrity and stability of an organism.
Berkeley Researchers Get First Look at Gene-Silencing Human RISC-Loading Complex.
Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it.
Tekmira Pharmaceuticals has announced that one of its collaborators, the National Cancer Institute, has presented promising preclinical data treating liver cancer using small interfering RNA enabled by the company's stable nucleic acid-lipid particles delivery technology.
