Abstract

Colorectal adenoma is a major precursor to colorectal cancer. Investigating the alteration of microRNA (miRNA/miR) expression during the progression from normal colorectal tissue to adenoma, and finally to colorectal carcinoma may aid our understanding of the biological mechanisms of colorectal tumorigenesis. In the present study, the miRNA expression profiles of normal colorectal tissue, adenoma and colorectal carcinoma from 6 patients were evaluated using miRNA‑sequencing. A total of 334 miRNAs were identified as differentially expressed. It was revealed that 34 miRNAs were upregulated in all 6 patients, including miR‑135b‑5p, miR‑18a‑5p and miR‑29b‑3p, and 28 miRNAs were downregulated, including miR‑1‑3p, miR‑338‑3p and miR‑218‑5p. Using bioinformatic analysis, the potential target genes of these 62 miRNAs were predicted and found to be enriched in ‘transcription, DNA‑dependent (GO:0006351)’, ‘signal transduction (GO:0007165)’, ‘small molecule metabolic process (GO:0044281)’ ‘PI3K/AKT signaling pathway (path ID:04151)’ and ‘MAPK signaling pathway (path ID:04010)’. The miRNA expression profiles identified in the present study may extend our understanding of the molecular mechanisms underlying colorectal tumorigenesis and promote novel perspectives for prevention, diagnosis and treatment.
