Tracesof the chemical are often found in mouse and humanurine, leading scientists towonderwhether the drug is being made naturally or being delivered by something the subjectsconsumed.
The new research shows that mice produce the "incrediblepainkiller"—and that humans and other mammalspossessthe same chemical road map for making it, said study co-author Meinhart Zenk, who studies plant-based pharmaceuticals at the Donald Danforth Plant Science Center in St. Louis, Missouri.
In the study, researchers injected mice with an extra dose of a natural brain chemical called tetrahydropapaveroline (THP), which humans and mice are known to produce.
Using a tool called a mass spectrometer to analyze the mouse urine, the team was able to tell that THPunderwentchemical changes in the body that created morphine, according to the study, published this week in the journal Proceedings of the National Academy of Sciences.
What's more, the study found that mouse morphine is produced in nearly the same way as the morphine inpoppies—the only morphine-making plants known to science.
