Cancer cells tricked into gobbling up poison

Researchers have discovered a biological mechanism that causes colon cancer cells to ingest toxins and die without harming other tissue, paving the way for an immunotoxin therapy for colorectal cancer.

They found that when they injected a monoclonal antibody into the GUCY2C cancer receptor in mice, the toxin-bound antibody attached itself to GUCY2C being expressed from metastases or primary colon cancer cells.
