We hypothesized that hormonal therapy favors the development of the hormone-resistant (HR) phenotype through epigenetic mechanisms. Human prostate cancer (Pca) tissues and in vitro and in vivo models were used to verify this hypothesis. We demonstrated that tumor cells continuously treated with BCLT or cultured in androgen depleted medium progressively acquire higher DNMT activity and expression. Increased DNMT expression and activity also paralleled the up-regul...
