Abstract

Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer‑associated mortality worldwide. CRC currently has no specific biomarkers to promote its diagnosis and treatment and the underlying mechanisms regulating its pathogenesis have not yet been determined. MicroRNAs (miRs) are small, non‑coding RNAs that exhibit regulatory functions and have been demonstrated to serve a crucial role in the post‑transcriptional regulatory processes of gene expression that is associated with cell physiology and disease progression. Recently, abnormal miR‑20a expression has been identified in a number of cancers types and this has become a novel focus within cancer research. High levels of miR‑20a expression have been identified in CRC tissues, serum and plasma. In a recent study, miR‑20a was indicated to be present in feces and to exhibit a high sensitivity to CRC. Therefore, miR‑20a may be used as a marker for CRC and an indicator that can prevent the invasive examination of patients with this disease. Changes in the expression of miR‑20a during chemotherapy can be used as a biomarker for monitoring resistance to treatment. In conclusion, miR‑20a exhibits the potential for clinical application as a novel diagnostic biomarker and therapeutic target for use in patients with CRC. The present study focused on the role and mechanisms of miR‑20a in CRC.
