Minireview: epigenetic changes in ovarian cancer.

ABSTRACT: Epigenetic aberrations, including DNA methylation, histone modifications, and micro-RNA dysregulation, are now well established in the development and progression of ovarian cancer, and their gradual accumulation is associated with advancing disease stage and grade. Epigenetic aberrations are relatively stable, associated with distinct disease subtypes, and present in circulating serum, representing promising diagnostic, prognostic, and pharmacodynamic biomarkers. In contrast to DNA mutations and deletions, aberrant gene-repressive epigenetic modifications are potentially reversible by epigenetic therapies, including inhibitors of DNA methylation or histone-modifying enzymes. Although epigenetic monotherapies have not shown activity against solid tumors, including ovarian cancer, preclinic
