Colorectal cancer treatment : new model
Based on existing research, the most suitable and well-documented cancer model for your purpose is colorectal cancer, specifically cell lines that are deficient in DNA Mismatch Repair (MMR). The key to proving your model would be to demonstrate a measurable shift in the mutation rate when cells are exposed to a specific chemotherapy drug. This creates a direct, observable cause-and-effect relationship that you can test. 🧬 Why This Cancer and Drug Work 1. The Cancer Model: MMR-Deficient Colorectal Cancer A well-studied example is the HCT116 human colon cancer cell line, which is deficient in MMR because of a defect in the hMLH1 gene. This deficiency makes the cells genomically unstable, resulting in spontaneous mutation rates that are 50 to 750 times higher than in cells with functional MMR. This high baseline of mutations provides a sensitive background to test the effect of drugs that can further influence mutation rates. 2. The Drug: Etoposide Among common chemotherapies, etopo...
