MicroRNAs (miRNAs) are endogenous small non-coding RNAs that function in the regulation of gene expression and regulate a wide array of biological processes, including carcinogenesis. Several mechanisms are involved in miRNA-associated cancer development, such as amplification or deletion of miRNA genes, abnormal transcriptional control of miRNAs, dysregulated epigenetic changes, and defects in miRNA biogenesis machinery. MiRNA-223 has been found to be a critical miRNA that is involved in a wide range of molecular processes. It is involved in the regulation of inflammatory cytokines, epithelial homeostasis, immune checkpoint signaling pathways, apoptosis, cell cycle, cell proliferation, invasion, and chemosensitivity. Published literature has demonstrated that miRNA-223 expression is associated with cancer development and prevention. Mir-223 functions as either a tumor suppressor or oncogene under certain circumstances, containing multiple targets or specific targets. Hence, miR-223 could be a potential candidate diagnostic biomarker, prognostic biomarker, or therapeutic target of cancer.

In 1993, the discovery of microRNAs in Caenorhabditis elegans (C. elegans) altered the paradigmatic view of RNA biology and post-transcriptional gene regulation. Further study revealed the role of microRNAs in disease development and progression. In particular, this review highlights microRNA-223 (miR-223 or miRNA-223) expression in malignant neoplastic disorders. miR-223 expression controls aspects of hematopoiesis and apoptosis, and cell proliferation, migration …
