By treating glioblastoma patients with a simple combination of resveratrol and copper, the researchers found dramatic reductions in tumor aggressiveness, cancer biomarkers, immune checkpoints, and stem-cell–related markers—all without side effects. Their approach focuses on “healing” tumors by eliminating harmful cell-free chromatin particles released from dying cancer cells, which normally inflame and worsen the disease. The findings hint at a future where inexpensive nutraceuticals could transform cancer therapy.
