摘　　要：BACKGROUND As a non-coding RNA molecule,circular RNAs(circRNAs)have significant specificity,and existing data suggest a close relationship between them and the prognosis of patients with gastric cancer(GC).However,this mechanism has no evidence yet.This article explores the functions of hsa_circRNA_102415 in the malignant behavior and potential downstream signaling of GC cells.The chosen approach is loss of signal and functional gain.AIM To investigate and analyze the relationship between hsa_circRNA_102415 and GC and explore its specific role.Results provide reference for other researchers to develop targeted treatment plans.METHODS The gene expression omnibus(GEO)database can be used to obtain the microarray dataset GSE83521.Data were analyzed using the GEO2R tool to identify differences in circRNAs between normal and GC samples.Quantitative real-time polymerase chain reaction was used to detect differentially expressed genes in GC tissue samples and adjacent cancer tissue samples.GC cells were transfected with small interfering-hsa_circRNA_104415 and plasmid DNA(pcDNA)-hsa_ircRNA_102415.Multiple detection methods,such as Transwell and cell counting kit 8,were used to evaluate cellular physiological activities,including cell invasion and proliferation.The relationship between Wnt family members 2B,microRNA(miR)-4529-5p,etc.,including argonaute 2-RNA immunoprecipitation and luciferase reporter genes was analyzed.Rescue experiments were conducted to analyze and explore the relationship between the malignant behavior of GC cells and hsa_circRNA_102415.RESULTS GEO2R analysis confirmed that hsa_circRNA_102415 had significantly higher expression levels in disease tissues.hsa_circRNA_102415 and miR-4529-5p showed a negative correlation in disease cells,suggesting that hsa_circRNA_102415 upregulated WNT2B expression in GC cells as a competing endogenous RNA for miR-4529-5p.miR-4529-5p mimic or small interfering-WNT2B reversed the effects of pcDNA-hsa_circRNA_102415 or miR-4529-5p inhibitor on cell malignant functions.C
