Menadione, a vitamin K precursor, shows promise in slowing prostate cancer in mice by disrupting cancer cell survival processes, with potential applications for human treatment and myotubular myopathy therapy.
Prostate cancer is a quiet killer. In most men, it’s treatable. While it’s treatable in many men, some cases prove resistant to all current therapies and become highly aggressive. Researchers at Cold Spring Harbor Laboratory (CSHL) have made a new discovery that could lead to a game-changing solution.
CSHL Professor Lloyd Trotman’s lab has found that the pro-oxidant supplement menadione slows prostate cancer progression in mice. The supplement is a precursor to vitamin K, commonly found in leafy greens. The story begins more than two decades ago.
In 2001, the National Cancer Institute’s SELECT trial sought to determine if an antioxidant vitamin E supplement could successfully treat or prevent prostate cancer. The trial involving 35,000 men was planned to last up to 12 years.

However, after just three years, participants were told to stop taking their supplements. Not only had vitamin E failed to slow or prevent prostate cancer—more men taking the supplement started to get the disease. Seeing these results, Trotman thought, ‘If an antioxidant failed, maybe a pro-oxidant would work.’ His new findings in mice show just that.
How Menadione Targets Cancer Cells
When mice with prostate cancer are given menadione, it messes with the cancer’s survival processes. Trotman’s team has discovered that menadione kills prostate cancer cells by depleting a lipid called PI(3)P, which works like an ID tag. Without it, the cells stop recycling incoming materials and eventually explode.
“It’s like a transport hub, like JFK. If everything that goes in is immediately de-identified, nobody knows where the airplanes should go next. New stuff keeps coming in, and the hub starts to swell. This ultimately leads to the cell bursting,” explains Trotman.
This causes the cancer’s progression to slow significantly in mice. Trotman now hopes to see the experiment translated to pilot studies in human prostate cancer patients:
“Our target group would be men who get biopsies and have an early form of the disease diagnosed. We wonder if they start to take the supplement, whether we would be able to slow that disease down.”
Amazingly, Trotman’s research suggests menadione may also prove effective against myotubular myopathy, a rare condition that prevents muscle growth in infant boys. Those diagnosed rarely live beyond early childhood. Trotman’s lab has found that depleting PI(3)P with menadione can double the lifespan of mice with this condition.
If the results hold up in humans, it would mean that men with prostate cancer can enjoy a better quality of life and more time with their families. It could also mean more precious time for children born with an incurable disease.
