Recently, Matrix metalloproteinase (MMP) has been shown to be regulated by vascular endothelial growth factor family members, especially placental growth factor (PLGF), as a potential mechanism underlying cancer invasion. Here, we studied the molecular relationship between PLGF and MMP7 in the OC.MethodsWe examined the levels of PLGF and MMP7 in the resected OC specimens and compared to paired adjacent non-tumor ovarian tissue. We also examined the correlation between PLGF and MMP7. We modified PLGF levels in a human OC cell line, OVCAR3, and analyzed the effects on MMP7. Prediction of microRNA (miRNA) binding to 3'-UTR of MMP7 mRNA was performed by bioinformatics analyses and confirmed by a dual luciferase reporter assay using miR-543-modifed OC cells. The levels of miR-543 were examined in the OC specimens, and the correlation between miR-543 and PLGF or MMP7 was performed.ResultsPLGF and MMP7 both significantly increased in the OC specimens, compared to paired adjacent non-tumor ovarian tissue. PLGF significantly increased MMP7 in the OC cells at protein level, but not at mRNA level. In OC cells, PLGF significantly decreased the levels of miR-543, which suppressed the translation of MMP7 mRNA via 3'-UTR binding. In OC specimen, miR-543 significantly decreased, compared to paired adjacent non-tumor ovarian tissue. An inverse correlation was detected between the levels of miR-543 and PLGF or MMP7 in the OC specimens.ConclusionMiR-543 inhibits translation of MMP7 through binding to the 3'-UTR of MMP7 mRNA in OC. PLGF suppresses miR-543, which activates MMP7-mediated cancer invasion."xsd:string |
