How the Treatment Works:
* targets Hydrogen Peroxide: The treatment focuses on increasing levels of hydrogen peroxide within cancer cells. cancer cells naturally produce more hydrogen peroxide than healthy cells.
* Inhibits PRX3: It works by blocking a protein called peroxiredoxin-3 (PRX3). PRX3 is responsible for breaking down hydrogen peroxide before it becomes toxic. By inhibiting PRX3,hydrogen peroxide builds up to lethal levels in cancer cells.
* Mitochondrial Action: The treatment affects the mitochondria within cancer cells – the powerhouses of the cell – where hydrogen peroxide breakdown normally occurs.
* Antioxidant Paradox: The research highlights that antioxidants, while generally considered protective, can actually help cancer cells survive by neutralizing the damaging effects of hydrogen peroxide.
The Compound Used:
* Thiostrepton: The research team started with a natural compound called thiostrepton, known for its anti-cancer properties.
* Molecular Breakdown: They systematically simplified the thiostrepton molecule to identify the smallest component still effective at inhibiting PRX3.
Overall Effect:
The treatment essentially overwhelms cancer cells with their own toxic byproduct (hydrogen peroxide), leading to their destruction. It’s described as a “cleaning team” inside the cancer cells, preventing them from neutralizing the harmful substance.
