Herin was downregulated (Figure 5A). Then, we performed transwell, wound healing and colony formation assay to detect alterations in cell invasion, migration and proliferation capability. The outcomes showed that overexpression of COL1A1 can certainly reverse the inhibitory effect of miR29a3p on cell migration (Figure 5B), invasion (Figure 5C) and proliferation (Figure 5D) capability to a particular extent.miR29a3p Can Partially Reverse the Function of circKRT7 in Ovarian Cancer CellsTo verify that the function of circKRT7 in ovarian cancer was mediated by miR29a3p, we performed a rescue experiment. CircKRT7 was knocked down in ovarian cancer cells, and after that miR29a3p inhibitor was transfected to inhibit the raise of miR29a3p caused by circKRT7 downregulation. Soon after detecting the expressions of circKRT7 and miR29a3p (Figure 6A), Western blot test was used to detect the expression of COL1A1, Ecadherin and vimentin in ES2 cells. The outcomes showed that inhibition of circKRT7 could release miR29a3p, which caused the downregulation of COL1A1, vimentin and Ecadherin upregulation. Soon after blocking with miR29a3p antisense oligonucleotides, the expression of COL1A1 and vimentin was restored (Figure 6B). We then used transwell, wound healing and colony formation experiments to confirm whether miR29a3p ASO could counteract the impact of cicKRT7 knockdown. Final results suggested that inhibition of miR29a3p could indeed restore the cell invasion (Figure 6C), migration (Figure 6D) and proliferation capability (Figure 6E) that inhibited by circKRT7 downregulation in ES2 and SKOV3 cells.Overexpression of miR29a3p Inhibits Ovarian Cancer Cell Invasion and ProliferationWe transfected miR29a3p mimics into ovarian cancer cells SKOV3 and ES2 after which detected the expression of COL1A1, Ecadherin and vimentin. Outcomes showed that the expressions of COL1A1 and vimentin expression have been suppressed right after miR29a3p mimics remedy, even though Ecadherin expression was upregulated (Figure 4A). The morphology of cells was also observed to be changed by an electron microscope (Figure 4B). In the exact same time, we employed transwell and wound healing tests to detect cell invasion and migration capacity. Benefits showed that overexpression of miR29a3p can inhibit ovarian cancer cell invasion and migration (Figure 4C and D).
