No / MicroRNAs are a relatively new class of small, noncoding RNA species that represent a cornerstone of cell biology, with diverse roles ranging from embryonic development to aging. miRNAs function to regulate posttranscriptional gene expression, are critical to the normal function of cells, and as such are frequently dysregulated during disease processes. In this chapter, we discuss the biogenesis and mechanism of action of miRNA and their role in cancer initiation, promotion, and progression. In addition, we discuss the most recently identified dual roles of miRNA in epigenetic gene regulation; how they are both regulators and regulated. Finally, we discuss the emerging roles of miRNA as epigenetic anti-cancer therapeutics, the current research examining inhibition of oncogenic miRNAs, and studies now establishing the potential of replacing lost, tumor-suppressive miRNA.
