A DNA-covered submicroscopic bead used to deliver genes or drugs directly into cells to treat disease appears to have therapeutic value just by showing up, researchers report. Within a few hours of injecting empty-handed DNA nanoparticles, Georgia Health Sciences University researchers were surprised to see increased expression of an enzyme that calms the immune response. In an animal model of rheumatoid arthritis, the enhanced expression of indoleomine 2,3 dioxygenase, or IDO,...

Mouse lifespan extended up to 24 percent with a single treatment A number of studies have shown that it is possible to lengthen the average life of individuals of many species, including mammals, by acting on specific genes. To date, however, this has meant altering the animals' genes permanently from the embryonic stage — an approach impracticable in humans. Researchers at the Spanish National Cancer Research Centre (CNIO), led by its director María Blasco, have proved...

Scientists from the Medical Research Council (MRC) Institute of Genetics and Molecular Medicine (IGMM) at the University of Edinburgh have discovered an enzyme that corrects the most common mistake in mammalian DNA. The mistake is the inclusion of individual bits of RNA within the DNA sequence, which the researchers found occurs more than a million times in each cell as it divides. The findings, published in Cell, suggest the RNase H2 enzyme is central to an important DNA repair mechanism...

Gene therapy strategies to prevent and treat inherited diseases of the retina that can cause blindness have progressed rapidly. Positive results in animal models of human retinal disease continue to emerge, as reported in several articles published in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The articles are available free on the Human Gene Therapy website. After 20 years of promising research, testing in animal models, and initial clinical trial...

Results open up field of T cell gene therapy for use in other diseases HIV patients treated with genetically modified T cells remain healthy up to 11 years after initial therapy, researchers from the Perelman School of Medicine at the University of Pennsylvania report in the new issue of Science Translational Medicine. The results provide a framework for the use of this type of gene therapy as a powerful weapon in the treatment of HIV, cancer, and a wide variety of other diseases. "We...

UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS. In a paper published in the May issue of the Journal of Virology, the UC Davis HIV team demonstrated both the safety and efficacy of transplanting anti-HIV stem cells into mice that represent models of infected patients. The technique, which involves replacing the immune system with stem cells engineered with a...

A research team, led by John Guy, M.D., professor of ophthalmology at Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine, has pioneered a novel technological treatment for Leber Hereditary Optic Neuropathy (LHON), an inherited genetic defect that causes rapid, permanent, and bilateral loss of vision in people of all ages, but primarily males ages 20-40. Genetic mutations in the mitochondria (part of the cell that produces energy) cause the disorder. Currently,...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
