Endosulfan exposure was recently associated to higher risk of prostate cancer incidence in humans probably due to its mutagenic [61], anti-androgen, estrogen agonist and aromatase inducer activites [62]; endosulfan increase activating phosphorylation of EGFR type 2 and it increases activity of several oncogenes like MAPK in prostate cancer cells [63]. The gene discussed is CYP19A1; the disease is prostate cancer.
