Role of circ-FNTA in the progression of bladder cancer (BCa) and its underlying mechanism were investigated. circ-FNTA level in BCa tissues and cell lines was detected. The prognostic potential of circ-FNTA was assessed by Kaplan-Meier methods and the proliferative and invasive abilities of BCa influenced by circ-FNTA were explored. Through dual-luciferase reporter gene assay, miRNA-451a, the target of circ-FNTA and the target gene of miRNA-451a, S1PR3 were determined. circ-FNTA was upregulated in BCa, especially in invasive BCa. High level of circ-FNTA indicated worse prognosis in BCa patients. Silence of circ-FNTA attenuated the proliferative and invasive abilities of T24 and UM-UC-3 cells. miRNA-451a was verified to be the target of circ-FNTA, which was downregulated in BCa cells. circ-FNTA negatively regulated the expression level of miRNA-451a. Moreover, S1PR3 was the downstream gene of miRNA-451a. Overexpression of miRNA-451a downregulated S1PR3 level in BCa cells. circ-FNTA accelerates the proliferative and invasive abilities of BCa through targeting miRNA-451a/S1PR3 axis, and indicates a poor prognosis of BCa patients.
