Fig. 9From: MicroRNA-545 suppresses progression of ovarian cancer through mediating PLK1 expression by a direct binding and an indirect regulation involving KDM4B-mediated demethylationDiagram presentation of the molecular mechanism. KDM4B promotes the demethylation of H3K9me3 to reduce the transcriptional suppression of PLK1, while miR-545 directly binds to PLK1 and KDM4B, therefore suppressing PLK1 expression through a direct targeting manner and an indirect regulation through KDM4B, thus alleviating OC developmentBack to article page
