Abstract

The present study was conducted to investigate the effects of RECK on cervical cancer cell migration and invasion to help understand relevant molecular mechanisms. QRT-PCR and western blot were respectively utilized to examine the transcriptional and translational levels of RECK in cervical cancer cell lines (HELA and C33A) and normal cell line (H8). After transfection with RECK overexpressing vectors, the expression of RECK mRNA, RECK and p53 signaling pathway-related proteins (p21, p53, bcl-2, and Bax) in cervical cancer cells were respectively examined using qRT-PCR and western blot. Cervical cancer cell migration after transfection was detected by wound healing assay and transwell assay. RECK expression was much lower in cervical cancer cell lines compared with normal cell line. Results of wound-healing assay results indicated that RECK could inhibit cervical cancer cell migration, and transwell assay results demonstrated that cell invasion was suppressed by RECK overexpression. Furthermore, western blot indicated that the overexpression of RECK could promote the activation of p53 signaling pathway by influencing related protein expression; whereas its inhibition by PFT-α could antagonize the effect of RECK on migrative and invasive abilities of cervical cancer cells. RECK could inhibit the migration and invasion of cervical cancer cells by activating p53 signaling pathway.
