Due to its molecular conformation similar to estradiol, nonylphenol exhibits several prostate cellular effects; in fact it stimulates cell survival and metastasis of hormone-dependent prostate cancer cells line by reducing mRNA levels of tumour suppressor genes like p27 and Bax [66] and all of these effects are similar to those observed for dihydrotestosterone (DHT) indicating the strong hormonal impact of this industrial chemical in prostate cancer biology. The gene discussed is BAX; the disease is Familial prostate cancer.
