    Abstract:
    Applying the method of multiple parallel sequencing on the MiSeq platform (Illumina, United States), a comparative analysis of miRNA expression in tumor and normal colon tissuie cells was performed. Forty miRNAs aberrantly expressed in cancer were detected. Among them, 15 and 25 miRNAs showed increased arid decreased expression, respectively, for all or most of the cases. Sixteen miRNA clusters were identified, which showed a coordinated or incompletely coordinated aberrant expression in colorectal cancer cells. In two (miR-183/182 and miR-106b/25) and four (miR-143/145, miR-497/195, miR-30e/30c-1, and miR-30a/30c-2) miRNA clusters, respectively, a statistically significant coordinated increase or decrease in expression was iegistered for all miRNAs withini the corresponding cluster. Three aberrantly expressed well-known miRNAs (miR-100-5p, mil-30d-5p, and miR-204-5p) were identified, which, however, had never 'before been associated with coloreictal cancer. The obtained results demonstrate the potential and promising application of 6 miRNA clusters with' coordinated aberrant expression as markers for colorectal cancer.
