Original Article


The present study aims to investigate the effects of microRNA-218 (miR-218) on the proliferation, migration, invasion, and apoptosis of gastric cancer (GC) cells by targeting LIM and SH3 domain protein 1 (LASP1). The GC cells in the logarithmic phase were selected and divided into five groups: the blank group, negative control (NC) group, miR-218 inhibitors group, miR-218 inhibitors + siLASP1 group, and miR-218 mimics + siLASP1 group. The miR-218 expression in each group was also detected by qRT-PCR. The CCK8 assay, Transwell migration, and invasion assays and flow cytometry were performed to determine the effects of miR-218 on cell proliferation, migration, invasion, and apoptosis of GC cells. Western blotting was conducted to measure LASP1 protein expression in GC cells after transfection. The qRT-PCR revealed that the transfection of miR-218 mimics could upregulate the miR-218 expression, and the transfection of miR-218 inhibitors could downregulate the miR-218 expression in the GC cells. Compared with the blank and NC groups, the proliferation, migration, and invasion of GC cells were significantly reduced in the miR-218 mimics, miR-218 inhibitors + siLASP1, and miR-218 mimics + siLASP1 groups but enhanced in the miR-218 inhibitors group. Similarly, compared with the blank and NC groups, the cell apoptosis rates in the miR-218 mimics, miR-218 inhibitors + siLASP1, and the miR-218 mimics + siLASP1 groups were significantly increased, while the miR-218 inhibitors group had a lower apoptosis rate. In conclusion, these results indicate that miR-218 could inhibit the proliferation, migration, and invasion and promote apoptosis of GC cells by downregulating LASP1 expression.
