When these proteins are removed, the cancer cell is sensitive to the body's normal defense mechanisms that are designed to eliminate cancerous cells. This synergistic mechanism also leads to phenoxodiol enhancing in a very potent way the sensitivity of cancer cells to the killing ability of standard anti-cancer drugs, as well as reversing chemo-resistance in cancer cells and restoring their sensitivity to those standard drugs.
