Abstract

CD44 is a prognostic indicator of shorter survival time in ovarian cancer. E‑cadherin fragmentation promotes the progression of ovarian cancer. However, the effects of CD44 and E‑cadherin overexpression on ovarian cancer cells have remained elusive. The present study aimed to investigate the effects of overexpression of CD44 and E‑cadherin on cell proliferation, adhesion and invasion of SKOV‑3 and OVCAR‑3 ovarian cancer cells. Overexpression of CD44 and E‑cadherin was achieved by transfecting SKOV‑3 and OVCAR‑3 cells with viruses carrying the CD44 or E‑cadherin gene, respectively. Expression of CD44 and E‑cadherin was detected by western blot analysis. The proliferation of SKOV‑3 and OVCAR‑3 cells was measured by a Cell Counting Kit‑8 at 0, 24 and 48 h after viral transfection. The adhesion ability of SKOV‑3 and OVCAR‑3 cells to the endothelial layer was detected. A Transwell invasion assay was utilized to assess the invasion ability of the cells. Overexpression of CD44 and E‑cadherin in SKOV‑3 and OVCAR‑3 cells was confirmed by western blot. Compared with the blank or negative control groups, the CD44 overexpression groups of SKOV‑3 and OVCAR‑3 cells exhibited an increased cell proliferation rate at 24 and 48 h, whereas overexpression of E‑cadherin did not alter the proliferation of these cells. Furthermore, compared with the blank and negative control groups, the cell adhesion and invasion ability in the CD44 overexpression groups of SKOV‑3 and OVCAR‑3 cells was markedly higher. There were no significant differences in adhesion ability between the E‑cadherin overexpression group and the blank/negative control group. Of note, overexpression of E‑cadherin decreased the invasive ability of SKOV‑3 and OVCAR‑3 cells. In conclusion, Overexpression of CD44 increased the proliferation, adhesion and invasion of ovarian cancer cells, while overexpression of E‑cadherin decreased the invasion of ovarian cancer cells.
