Compared with the Ctrl-SW579 group, the cell apoptosis rate in the ABCE1-SW579 group was significantly higher (P < 0.01), and proliferation, migration, and invasion were significantly reduced (P < 0.05).
These results revealed that ABCE1 is closely associated with cell proliferation, invasion and migration in esophageal cancer and silencing the ABCE1 gene by electroporation can significantly reduce the proliferation, invasion and migration capacity of EC109 cells in vitro.
Furthermore, ABCE1‑siRNA was found to inhibit proliferation and invasion in breast cancer cells, significantly induce breast cancer cell apoptosis (P<0.05) in vitro and increase the protein expression of RNase L. These findings showed that ABCE1 had an important role in proliferation, invasion and apoptosis in MCF‑7 human breast cancer cells and that ABCE1 may inhibit intracellular RNase L activity, which inhibits the 2‑5A/RNase L pathway, interfering with the biological characteristics of breast cancer cells.
