Jurassic Pot: Wageningen Scientists “Resurrect” Ancient Cannabis DNA for New Medicines

Wageningen – In a scientific feat reminiscent of Jurassic Park, researchers at Wageningen University & Research (WUR) have successfully brought ancestral cannabis enzymes back to life. By reconstructing the genetic history of the plant, they have unlocked a biological “time machine” that could revolutionize pain medication. The study focuses on producing Cannabichromene (CBC), a rare therapeutic compound that modern cannabis plants have largely “forgotten” how to make efficiently.

The Breakthrough: Resurrecting the Ancestors

Modern cannabis plants are specialists. Over thousands of years of evolution and human breeding, they have become incredibly efficient at producing two specific compounds: THC (the psychoactive component) and CBD (the relaxing component). However, this specialization came at a cost.

Robin van Velzen, the biosystematist leading the research at WUR, discovered that the enzymes in modern plants are “fussy”—they only do one job. To fix this, his team used computational reconstruction to determine what the DNA of the cannabis plant looked like millions of years ago. They then synthesized these “ancestral enzymes” in the lab.

The result? The ancient enzymes were “promiscuous” (scientifically speaking). Unlike their modern descendants, they could produce a wide variety of cannabinoids, including the elusive CBC, with much greater flexibility.

The “Lazy” Evolution of Modern Cannabis

This research offers a fascinating glimpse into plant evolution. “What was once an evolutionary ‘loose end’ is now very useful,” explains Van Velzen.

In the wild, cannabis plants evolved to pump out THC likely as a defense mechanism against pests (or to attract humans!). The enzymes responsible for this became highly specialized, losing the ability to create other compounds. By rewinding the genetic clock, the Dutch team has recovered the “Swiss Army Knife” capability of the original plant, allowing them to manipulate production lines that nature shut down eons ago.

Why CBC? The Medical Holy Grail

Why all this effort? The target is Cannabichromene (CBC).

Currently, CBC appears only in trace amounts (often less than 1%) in most cannabis strains. However, medical research suggests CBC has potent properties:

• Anti-inflammatory: More effective than CBD for certain types of swelling.
• Pain Relief: Blocks pain perception without the “high” of THC.
• Neuroprotection: Early studies suggest it may help brain cell growth.

By using the resurrected ancestral enzymes, scientists can potentially mass-produce CBC, making it available for pharmaceutical trials for the first time in history.

Brewing Medicine: No Plants Required

The most disruptive part of this research is that it doesn’t require fields of marijuana. The team isn’t growing plants; they are using yeast.

By inserting the ancestral cannabis DNA into simple baker’s yeast, the microorganisms act as “mini-factories.” They consume sugar and spit out pure CBC. This method, known as biosynthesis, is:

• Scalable: Can be produced in vats like beer.
• Pure: No pesticides, heavy metals, or variable crop quality.
• Sustainable: Uses a fraction of the water and energy compared to greenhouse cultivation.

Future Implications: Customized Cannabinoids

This breakthrough at Wageningen cements the Netherlands’ status as a global leader in “Green Life Sciences.” The ability to use flexible, ancestral enzymes means we are no longer limited to what the plant wants to give us.

Scientists can now theoretically design “Frankenstein enzymes” to produce entirely new cannabinoids that don’t exist in nature—compounds designed specifically to target cancer cells or treat epilepsy, with zero side effects. We are moving from the era of “Herbal Medicine” to “Precision Plant Engineering.”

Key Takeaways

• Genetic Time Travel: WUR researchers reconstructed enzymes from millions of years ago.
• Flexibility: Ancient enzymes are more versatile than modern, specialized ones.
• Focus on CBC: The goal is to mass-produce Cannabichromene for pain relief.
• Yeast over Plants: The future of medical cannabis is likely fermentation, not farming.
