--- - |2- Abstract Aberrant microRNA (miR) expression is implicated in multiple human malignancies. miR‐21, acting as a proto‐oncogene, is involved in a variety of cellular processes and tumorigenesis and is frequently overexpressed in some cancer types. Several tumor suppressors, metastatic, and apoptotic genes have been identified as miR‐21 targets, including Ras homolog gene family member B, PTEN, Sprouty2, programmed cell death 4, Integrin‐β4, and E‐cadherin thereby regulating tumor growth, invasion, and metastasis. There is a growing evidence that miR‐21 expression is associated with clinical outcomes in patients with colorectal cancer (CRC). In this review, we summarize the potential diagnostic, prognostic, and therapeutic values of miR‐21 in CRC progression for a better understanding and hence a better management of this disease. - Journal of Cellular Physiology, EarlyView.
