Colorectal Tumors Use Mitochondrial Complex II to Stockpile Iron, but Eliminating It Causes Cell Death

Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death

Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type of iron-related cell death called ferroptosis. But in cancer cells, the iron continues to accumulate well beyond normal levels without succumbing to expected cell death processes.

New Study Reveals Mechanisms Behind High Iron Levels in Colorectal Cancer

University of Michigan Rogel Cancer Center researchers have unveiled a groundbreaking metabolic mechanism that colorectal cancer cells exploit to maintain exceptionally high iron levels, a discovery that opens promising avenues for targeted cancer therapies. Published recently in Cell Metabolism, this study provides an unprecedented insight into how tumor cells sidestep iron toxicity and evade a form of cell death known as ferroptosis, potential…
