The $73.5 billion global biotech business may soon have to grapple with a discovery that calls into question the scientific principles on which it was founded.
Last month, a consortium of scientists published findings that challenge the traditional view of how genes function. The exhaustive four-year effort was organized by the United States National Human Genome Research Institute and carried out by 35 groups from 80 organizations around the world. To their surprise, researchers found that the human genome might not be a "tidy collection of independent genes" after all, with each sequence of DNA linked to a single function, such as a predisposition to diabetes or heart disease.
Instead, genes appear to operate in a complex network, and interact and overlap with one another and with other components in ways not yet fully understood. According to the institute, these findings will challenge scientists "to rethink some long-held views about what genes are and what they do."
Biologists have recorded these network effects for many years in other organisms. But in the world of science, discoveries often do not become...
