Abstract: BACKGROUND: Circular RNAs (circRNA) play key regulatory roles in cancer progression. Human circRNA microarray was performed to screen for abnormally expressed circRNA in gastric cancer tissues. In this study, we found circRNA102958 was up-regulated in gastric cancer tissues and cell lines. METHODS: The hsa_circRNA_102958 levels were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) in gastric tissue and cell. Then, the association between the expression level of hsa_circRNA_102958 and the clinicopathological features of patients with gastric cancer was further analyzed. Finally, a network of hsa_circRNA_102958-miRNA-mRNA interactions was predicated. RESULTS: In this study, we analyzed 30 patients and found that hsa_circRNA_102958 was significantly overexpressed in gastric cancer tissues compared with paired adjacent normal tissues. Clinicopathological features showed that hsa_circRNA_102958 level in GC tissues was positively associated with TNM stage (p= 0.032). The area under the ROC curve was 0.74. Finally, a total of 5 miRNAs were predicted to have an interaction with hsa_circRNA_102958. CONCLUSIONS: hsa_circRNA_102958 may be a potential novel and stable biomarker for the diagnosis of gastric carcinoma.
