microRNAs (miRNAs) are small non-coding RNA transcripts (20-24 nucleotides) that bind to their complementary sequences in the 3'-untranslated regions (3'-UTR) of targeted genes to negatively or positively regulate their expression. miRNAs affect the expression of genes in cells, thereby contributing to several important biological processes, including tumorigenesis. Identifying the miRNA cluster as a human embryonic stem cell (hESC)-specific miRNAs initially led to the identification of miR-371, miR-372, miR-373, and miR-373*, which can ultimately be translated into mature miRNAs. Recent evidence suggests that miR-371-373 genes are abnormally expressed in various cancers and act either as oncogenes or tumor suppressors, indicating they may be suitable as molecular biomarkers for cancer diagnosis and prevention. In this article, we summarize recent studies linking miR-371-373 functions to tumorigenesis and speculate on the potential applications of miR-371-373 as biomarkers for cancer diagnosis and treatment.
