In California, Michael Rose, who created the aged fruit flies, has not yet found the genes responsible for his insects' longevity, but does believe genetic manipulation can be a key to prolonging life. Manipulating any senescence genes could be years--indeed, decades--away. But the alternative--subjecting human beings to...
Meanwhile, more and more genes involved in the aging process are giving up their secrets. At the Veterans Affairs Medical Center in Seattle, a group led by molecular geneticist Gerard Schellenberg has identified the human gene responsible for the disorder known as Werner's syndrome. People suffering from Werner's...
Running parallel to Schellenberg's work is research being conducted at the New York State Institute for Basic Research into the more devastating Werner's-like disorder known as progeria. People suffering from progeria grow old precociously too, but at a much faster rate; they are claimed by the infirmities...
The problem facing any scientist trying to find a genetic lever on the aging process is the sheer number of genes involved. Geneticist George Martin at the University of Washington in Seattle, who was involved in the discovery of the Werner's gene, believes that even if only a few...
For the time being, therefore, many researchers are shifting their focus to goals that are more achievable. If the genes responsible for regulating senescence can't yet be manipulated, they wonder, is it possible to directly treat parts of the body they affect? Jerry Shay, a biologist specializing in cancer...
