Overexpression of Mirna 26A and 26B with Mmp-9 are Valuable Diagnostic Biomarkers for Colorectal Cancer Patients

Abstract

<b>Background:</b> The key role of miRNA expression in incidence and progression of colorectal cancer (CLC) have been developed over the last decade. <b>Materials & methods:</b> A total of 153 subjects were enrolled into two phases: 14 selected miRNAs were first evaluated in 50 subjects, then miR-26a and miR-26b relative expression were further evaluated in 103 subjects and their target protein MMP-9 was measured. <b>Results:</b> miR-26a and -26b showed highly significant overexpression. Both miR-26a and -26b (p < 0.001) had high diagnostic efficacy for CRC. There was a significant increase in serum MMP-9 protein in CRC patients with positive correlation with miR-26a and -26b expression levels (p < 0.001). <b>Conclusion:</b> miRNA 26a and 26b with MMP-9 can be used as diagnostic biomarker for CRC patients.
