Opium and marijuana research go underground

High-security Canadian mine used for biochemical research into opium poppy and cannabis

The world’s leading expert on the opium poppy has joined forces with researchers working on another infamous drug-producing plant – cannabis – in hopes of finding new uses for the much-maligned sources of heroin and marijuana.

Peter Facchini, professor of Biological Sciences and Canada Research Chair in Plant Biotechnology, has received a $650,000 NSERC Strategic Project Grant to create new varieties of opium poppy and cannabis that can be used for medicinal and industrial purposes, but will have no value as illicit drugs. And his work is taking him where few Canadians have gone before: Deep underground into the country’s ultra high-security medicinal marijuana growth facility.

“It’s certainly unusual for a plant biochemist to work in a copper mine hundreds of metres underground,” Facchini said. “This is a really great project that involves two of the world’s most important medicinal plants and is clearly unique in the plant biology field.”

Facchini and a new team of U of C postdoctoral researchers have teamed up with Saskatoon-based Prairie Plant Systems Inc., the National Research Council – Plant Biotechnology Institute, the Alberta Research Council and the University of Saskatchewan to create and study mutant varieties of opium poppy and cannabis in an unused portion of a copper and zinc mine near Flin Flon, Manitoba. Prairie Plant Systems produces medicinal marijuana under contract with Health Canada in this state-of-the-art facility.

Despite awareness of the importance of crop diversification for the long-term success of agriculture in Canada, few plants are cultivated for the production of high-value bioproducts. Opium poppy accumulates the alkaloids morphine, codeine and thebaine, and cannabis produces psychoactive cannabinoids and is used as a source of high-quality fiber and oil. The domestic market for codeine, morphine and oxycodone, which is derived from thebaine, is in excess of $1.6 billion annually, all of which is currently imported. “Canada is well-positioned to support the development of new crops cultivated for the production of valuable bioproducts, such as pharmaceuticals and fibers,” says Facchini. The research will identify novel genes for use in the metabolic engineering of opium poppy to accumulate high-value pharmaceutical alkaloids and to block cannabinoid production in cannabis. The latter will allow for a safe, legal, made-in-Canada cannabis crop that will have virtually none of the mind-altering chemical of marijuana but can be grown for hemp fibre, oil and food.

“The overall theme of this work is to modify plants to make them more useful as crops and chemical factories,” Facchini said. “Alberta is quickly becoming a leader in this area, especially in the area of biofuels. The immense potential of plants as sources of high-value bioproducts for the agricultural and pharmaceutical sectors also needs attention.”

The Biosecure Underground Growth Chamber is in a mine owned by Hudson Bay Smelting & Mining Co. Ltd. Facchini says it is a superb venue for his research. “It’s not what you would picture an old mine shaft to be. It’s clean and well-lit, it’s kept at a constant temperature and it’s one of the most secure places in the country,” he says. “It gives a whole new meaning to ‘mining our data.’”

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
