"In cisplatin-resistant ovarian cancer cells c-Myc enhances the expression of EZH2 by directly suppressing miR-137 that targets EZH2 mRNA. Inhibition of c-Myc-miR-137-EZH2 pathway re-sensitizes resistant cells to cisplatin. Clinical studies further confirm the activated c-Myc-miR-137-EZH2 pathway in platinum drug-resistant or recurrent ovarian cancer patients."xsd:string
