Three possible diagnostic biomarkers for gastric cancer: miR-362-3p, miR-362-5p and miR-363-5p

Aim: MicroRNAs can be regarded as biomarkers for gastric cancer (GC) diagnosis in the early stages. This study assesses the expression levels of miR-362-3p, miR-362-5p and miR-363-5p as potential biomarkers for GC. Materials & methods: The expression levels of the miRNAs in 90 pairs of GC and adjacent normal tissue samples were analyzed by quantitative real-time reverse transcription PCR (qRT-PCR) and some bioinformatics tools were utilized for analyzing the target genes and possible molecular pathways in which these miRNAs participate. Results & conclusion: There was a significant overexpression of the miRNAs in GC cells and an outstanding correlation between their overexpression with some clinicopathological features of the patients.
