Background: Long noncoding RNAs (lncRNAs) have been considered as significant regulators in many cancer progression, such as proliferation, invasion and other path of evolution. Nevertheless, we have not had a grasp of the role of lncRNA TP73-AS1 in gastric cancer (GC).Methods: qRT-PCR analysis was first conducted to examine the TP73-AS1 level in both GC tissues and cell lines. Then gain or loss-of-function assays were carried out to detect the effect of TP73-AS1 on GC development. In mechanism, bioinformatics analysis and luciferase reporter assays were used to search and confirm the target gene of TP73-AS1. Finally, rescue assays were performed to confirm the influence of TP73-AS1-miR-194-5p-SDAD1 axis on GC development.Results: TP73-AS1 was upregulated in GC tissues and cell lines. Furthermore, TP73-AS1 exerted oncogenic role in GC through promoting cell growth and metastasis. In addition, TP73-AS1 was certified as a ceRNA by regulating miR-194-5p/SDAD1 axis.Conclusions: TP73-AS1 accelerates tumor progression in gastric cancer through regulating miR-194-5p/SDAD1 axis.
