Drinking Foam with Carbon Monoxide Improves Experimental Therapy
Researchers at the University of Iowa, along with their colleagues, explored a unique avenue in cancer treatment by investigating whether smokers fared better than non-smokers in a clinical trial for an experimental cancer therapy. The team developed a special foam infused with carbon monoxide, and the results, recently published in Advanced Science, revealed promising outcomes.
In the quest for innovative cancer treatments, scientists often look for ways to exploit differences between cancer cells and healthy cells. The team focused on autophagy, the cell's natural recycling system, which is known to be more active in cancer cells. By inhibiting autophagy, researchers hoped to target cancer cells more effectively. Previous clinical trials testing autophagy inhibitors yielded mixed results, prompting the researchers to delve deeper into the intricacies of the process.
Dr. James Byrne, an assistant professor at the University of Iowa and senior author of the study, shared that analyzing data from past trials showed an unexpected trend: smokers seemed to respond better to autophagy inhibitors than non-smokers. This led to the hypothesis that carbon monoxide, which is elevated in smokers, might play a role in enhancing the anti-cancer effects of autophagy inhibitors.
"While we definitely don't recommend smoking, this suggested that elevated carbon monoxide might improve the effectiveness of autophagy inhibitors. We want to harness that benefit and take it into a therapeutic platform," says Dr. Byrne.
To test their hypothesis, the researchers created a drinkable foam infused with carbon monoxide, utilizing gas-entrapping materials (GEMs). In experiments with mice carrying pancreatic and prostate cancers, the carbon monoxide foam, combined with autophagy inhibitors, significantly reduced tumor growth and progression. Similar anti-cancer effects were observed in human prostate, lung, and pancreatic cancer cells in laboratory dishes.
Dr. Byrne envisions moving this approach into human clinical trials, emphasizing the potential of safe, therapeutic levels of carbon monoxide delivered through GEMs to enhance the effectiveness of autophagy inhibitors. He believes this promising new avenue could lead to improved therapies for various types of cancer.
In summary, this innovative study opens doors to exploring the synergy between carbon monoxide and autophagy inhibitors as a potential breakthrough in cancer treatment.
