Stanford bioengineers have hacked the DNA of yeast, reprograming these simple cells to make opioid-based medicines* via a sophisticated extension of the basic brewing process that makes beer.
Led by Associate Professor of Bioengineering Christina Smolke, the Stanford team has already spent a decade genetically engineering yeast cells to reproduce the biochemistry of poppies, with the ultimate goal of producing opium-based medicines, from start to finish, in fermentation vats.
“We are now very close to replicating the entire opioid production process in a way that eliminates the need to grow poppies, allowing us to reliably manufacture essential medicines while mitigating the potential for diversion to illegal use,” said Smolke, who outlines her work in the August 24 edition of Nature Chemical Biology.
Smolke added five genes from…
