Abstract
BACKGROUND: Circular RNAs (circRNAs) play a crucial role in the occurrence of several diseases including cancers. However, little is known about circRNAs' diagnostic values for gastric cancer, one of the worldwide most common diseases of mortality. METHODS: The hsa_circ_0003159 levels in 108 paired gastric cancer tissues and adjacent non-tumorous tissues from surgical patients with gastric cancer were first detected by real-time quantitative reverse transcription-polymerase chain reaction. Then, the relationships between hsa_circ_0003159 expression levels in gastric cancer tissues and the clinicopathological factors of patients with gastric cancer were analyzed. Finally, its diagnostic value was evaluated through the receiver operating characteristic curve. RESULTS: Compared with paired adjacent non-tumorous tissues, hsa_circ_0003159 expression was significantly down-regulated in gastric cancer tissues. What is more, we found that hsa_circ_0003159 expression levels were significantly negatively associated with gender, distal metastasis, and tumor-node-metastasis stage. CONCLUSIONS: All of the results suggest that hsa_circ_0003159 may be a potential cancer marker of patients with gastric cancer.
