    A gene silencing approach can save monkeys from high doses of the most lethal strain of Ebola virus in what researchers call the most viable route yet to treating the deadly and frightening infection. They used small interfering RNAs or siRNAs, a new technology being developed by a number of companies, to hold the virus at bay for a week until the immune system could take over. Tests in four rhesus monkeys showed that seven daily injections cured 100 per cent of them. U.S. government researchers and a small Canadian biotech company, Tekmira Pharmaceuticals, worked together to develop the new...

    WELLINGTON (AFP) - Scientists in New Zealand and Japan have created a "tear-free" onion using biotechnology to switch off the gene behind the enzyme that makes us cry, one of the leading researchers said Friday. The discovery could signal an end to one of cooking's eternal puzzles: why does cutting up a simple onion sting the eyes and trigger teardrops? The research institute in New Zealand, Crop and Food, used gene-silencing technology to make the breakthrough which it hopes could lead to a prototype onion hitting the market in a decade's time. Colin Eady, the institute's senior scientist, said the...
  • 2 U.S. Researchers Win Nobel for Work on Genes

    This year’s Nobel prize for physiology or medicine has been awarded to two American researchers, Andrew Z. Fire and Craig C. Mello, for a far-reaching discovery about how genes are controlled within living cells. The discovery was made in 1998, only eight years ago. It has been recognized with unusual speed by the Nobel Foundation in Stockholm, which often lets decades elapse before awarding its accolade. The two scientists’ finding clarified a series of puzzling results obtained mostly by plant biologists trying to change the colors of petunias. By clarifying what was going on, they discovered a novel and quite...
  • Gene silencing directs muscle-derived stem cells to become bone-forming cells

    Using a relatively new technology called RNA interference to turn off genes that regulate cell differentiation, University of Pittsburgh researchers have demonstrated they can increase the propensity of muscle-derived stem cells (MDSCs) to become bone-forming cells. Based on these results, the investigators believe that by turning off specific genetic factors they can control the capacity of MDSCs as a means of treating various musculoskeletal diseases and injuries. RNA interference is a simple yet powerful technique that uses short interfering RNAs (siRNAs) – small molecules that prevent a gene from being expressed – to turn off the production of specific proteins...
