The authors found that the treated DMBA-induced breast cancer in a rat model with 0.1% molecular iodine/potassium iodide induced the expression of LPO, which contributes to the antineoplastic effect, inducing apoptosis through PPARγ/caspases and preventing estrogen-induced DNA adducts in pre-cancer and cancerous cells. The gene discussed is LPO; the disease is cancer.
