Objective.
Circular RNAs (circRNAs) have been reported to be widely involved in pathological processes of various cancers.
However, little is known about their diagnostic values in early gastric cancer (EGC).
This study is aimed at exploring whether circulating circRNAs in plasma could act as biomarkers for EGC diagnosis.
Materials and Methods.
Mass spectrometry (MS) was performed to identify the proteins that at significantly aberrantly levels in gastric cancer (GC) tissues.
The target circRNA was identified by bioinformatics analysis.
A receiver operating characteristic (ROC) curve was generated to evaluate the diagnostic utility.
Results.
MS revealed that the ribosomal protein L6 (RPL6) expression was significantly downregulated only in EGC tissues vs.
nontumorous tissues; this was validated by western blotting (n=30, p=0.0094).
Bioinformatics analysis predicted that there is a hsa_circ_0006848/hsa_miR-329-5p/RPL6 axis in GC progression.
The hsa_circ_0006848 expression was significantly downregulated in EGC tissues (vs.
nontumorous tissues, n=30, p=0.0073) and plasma samples from EGC patients (vs.
paired healthy volunteers, n=30, p=0.0089).
In addition, the hsa_circ_0006848 plasma level in postoperative patients was significantly higher than that of preoperative patients (n=30, p=0.047).
Furthermore, the decreased hsa_circ_0006848 expression in plasma was negatively correlated with poor differentiation (p=0.037) and tumor size (p=0.046).
The area under the ROC curve (AUC) of hsa_circ_0006848 in plasma was 0.733, suggesting a good diagnostic value.
The plasma hsa_circ_0006848 level combined with the carcinoembryonic antigen (CEA), carbohydrate-associated antigen 19-9 (CA19-9), and carbohydrate-associated antigen 72-4 (CA72-4) level increased the AUC to 0.825.
Conclusion.
Our results indicated that plasma hsa_circ_0006848 may be a novel noninvasive biomarker in EGC diagnosis.
