SiRNA and epigenetic aberrations in ovarian cancer.

Abstract:

:Ovarian cancer has the most noteworthy lethal rate around gynecologic malignancies, and it is also considered as the fourth most frequent cancer in the woman in world. Two most critical barriers to treatment of ovarian malignancy are absence of early diagnostic markers and advancement of drug resistance after therapy, especially in advanced stages. Various epigenetic changes have been recognized in ovarian cancer. Recent progresses in our understanding of molecular pathogenesis of ovarian malignancy have dramatically provided potential new targets for molecularly targeted therapies. In very recent years, small interfering RNA (siRNA)-mediated gene silencing has been emerging as a novel treatment modality in preclinical studies in the light of its strong gene-specific silencing. Gene suppression mediated by RNA interference (RNAi) significantly suppressed gene expression at the messenger RNA (mRNA) and protein levels. SiRNAs have therapeutic potential for ovarian cancer through various mechanisms. In this review, we not only provide an overview of siRNA designing for epigenetic silencing of genes aberrantly expressed in ovarian cancer but also we will highlight that the epigenetically silenced genes offer new targets for therapeutic approaches based on re-expression of tumor suppressor genes via demethylating and deacetylating drugs.
