Purpose: This study was designed to explore the functional role of FYVE, RhoGEF, and PH domain containing 5 antisense RNA 1 (FGD5-AS1) and the underlying regulatory mechanism in the progression of glioblastoma (GBM).
Materials and Methods: FGD5-AS1 expression was analyzed in The Cancer Genome Atlas (TCGA), and then detected in GBM tissues and cells by quantitative reverse-transcription polymerase chain reaction. Viability, migration, and invasion of GBM cells were assessed using the MTT, wound healing, and transwell assays, respectively. StarBase/TargetScan analysis and dual-luciferase reporter gene (DLR) assay were performed to investigate the relationship between FGD5-AS1/tumor protein D52 (TPD52) and miR-103a-3p. A xenograft tumor model was established to evaluate the role of FGD5-AS1 in GBM tumorigenesis in vivo.
Results: FGD5-AS1 was overexpressed in GBM tissues and cells, and silencing of FGD5-AS1 expression resulted in the inhibition of the viability, migration, and invasion of GBM cells. miR-130-3p was a target of FGD5-AS1, and its expression was negatively regulated by FGD5-AS1. Silencing miR-103a-3p expression resulted in the abrogation of the inhibitory effects of si-FGD5-AS1 on the viability, migration, and invasion of GBM cells. TPD52 was a target of miR-103a-3p and suppressed the antitumor effects of FGD5-AS1 silencing on GBM cells. In addition, FGD5-AS1 silencing inhibited the growth of xenograft tumors in vivo by modulating the miR-103a-3p/TPD52 axis.
Conclusion: Silencing of FGD5-AS1 inhibited the viability, migration, and invasion of GBM cells by regulating the miR-103a-3p/TPD52 axis.
