HOXC10 promotes tumour metastasis by regulating the EMT-related gene Slug in ovarian cancer

Figure 4. HOXC10 expression is regulated by miR-222-3p. (A) A Venn diagram was used to identify the candidate miRNAs targeting HOXC10. (B) Relative expression of miR-222-3p in cell lines. P=0.0004, P<0.0001, and P<0.0001. (C) Transwell assay of PM cells transfected with the miR-222-3p mimic, miR-222-3p inhibitor or negative control. P=0.0007 and P=0.0012. Scale bars, 100 μm. (D, E) Relative mRNA and protein expression levels of HOXC10 in PM cells transfected with the miR-222-3p mimic or negative control. P<0.0001 and P=0.0037. (F, G) Relative mRNA and protein expression levels of HOXC10 in Skov3 cells transfected with the miR-222-3p inhibitor or negative control. P=0.0041 and P=0.0002. (H) Schematic diagram of the binding site for miR-222-3p in the HOXC10 3’UTR. (I) PM cells were cotransfected with a plasmid containing the full-length HOXC10 3’UTR and increasing concentrations of the miR-222-3p mimic. P=0.0108 and P=0.0005. (J) PM cells were cotransfected with a plasmid containing the mutated full-length HOXC10 3’UTR and increasing concentrations of the miR-222-3p mimic. P=0.4474 and P=0.3730.
