MicroRNAs (miRNAs) constitute a large family of small, non-coding RNAs with the capacity to regulate gene expression post-transcriptionally. miRNAs appear to hold promise of mechanistic explanations for various physiological and pathological processes. miRNA-223 is highly conserved and preferentially expressed in the hematopoietic system in regulation of myeloid differentiation. Recently, increasing evidence suggests that miRNA-223 may also play an essential part in both hematological malignancies and solid tumors. miRNA-223 can function as either an oncogene or a tumor suppressor gene, which is achieved by targeting a wide range of genes and regulating downstream signal transduction. As yet, the function of miR-223 in cancer has not been fully characterized and understood. To make it more clear, this review firstly summarizes the present understanding of the regulation of miR-223 at the molecular level, its crucial role in oncogenesis, development, and metastasis, its function as a diagnostic and prognostic biomarker and finally, its potential applications in monitoring and therapy of diverse types of malignancies.
