BACKGROUND: Human umbilical cord mesenchymal stem cell (hucMSC)-derived exosomes have been reported to be effective in the treatment of cancer. The miR-214-3p is a suppressor miRNA that has been extensively studied and has been proposed as a diagnostic and prognostic biomarker in some cancers.
OBJECTIVES: The aim of this study was to investigate whether the regulatory mechanism of hucMSC-derived exosomal miR-214-3p with GLUT1 and ACLY affects the proliferation and apoptosis of gallbladder cancer (GBC) cells.
MATERIAL AND METHODS: We found that the target genes of miR-214-3p on the TargetScan website contain GLUT1 and ACLY, and the targeting relationship was verified using luciferases. The GBC-SD cells overexpressing GLUT1 and ACLY were constructed to determine proliferation, apoptosis, migration, and other cellular activities.
RESULTS: We identified hucMSCs and exosomes, and found that the exosomes contained miR-214-3p. Furthermore, TargetScan predicted that miR-214-3p had base interactions with ACLY. Dual luciferase assays showed that miR-214-3p could inhibit ACLY (p < 0.05). The results of quantitative reverse transcription polymerase chain reaction (RT-qPCR) and western blot showed that exosomal miR-214-3p could inhibit the expression of ACLY and GLUT1 (p < 0.05). Exosomal miR-214-3p can inhibit the proliferation, cloning and migration of GBC-SD cells (p < 0.05). The apoptosis of GBC-SD cells was increased (p < 0.05). The GBC-SD cells overexpressing ACLY and GLUT1 could reverse the efficacy of miR-214-3p.
CONCLUSIONS: Exosomal miR-214-3p can inhibit the downstream expression of ACLY and GLUT1. The ACLY and GLUT1 could affect the proliferation and apoptosis of GBC-SD cells.
