A total of 63 miRNAs were up-regulated and 20 miRNAs were down-regulated in rat POF tissues versus the control tissues. qRT-PCR verified some of these altered miRNAs, i.e. miR-29a and miR-144 were down-regulated in POF tissues, which may target expression of PLA2G4A that is involved in prostaglandin biosynthesis, whereas miR-27b and miR-190 were up-regulated in POF tissues by negative control of PAPPA and CCL2 expression, respectively, both of which have been shown to relate to response to hormone stimulus.
