Fig. 5: miR-125b inhibited trophoblast invasion via KCNA1 mediation.

The invasiveness of HTR8/SVneo cells transfected with miR-125b, miR-125b inhibitor, and KCNA1 siRNA were determined using Transwell insert invasion assay, as presented the typical field in a and relative invasion index in b. Nā=ā3 performed in triplicates and results are presented as meanā±āSEM. Statistical comparison between miR-125b mimics (or inhibitor) and the negative control was performed using Student t test, with pā<ā0.05 considered as significant. *pā<ā0.05, **pā<ā0.01. c Typical microscope fields of Transwell insert invasion assays to examine cell invasion in HTR8/SVneo cells transfected with either KCNA1 overexpressing pcDNA 4 vector (pcKCNA1) or pcDNA 4 vector (pDNA4). miR-125b mimic or negative control miRs was co-transfected. d Relative invasion index based on 3 independent experiments performed in triplicates and results are presented as meanā±āSEM. with pā<ā0.05 considered as significant. *pā<ā0.05, **pā<ā0.01.
