MicroRNAs (miRNAs) are important players in all biological pathways in multicellular organisms. Over 1,400 human miRNAs have been identified, and many are conserved among vertebrates and invertebrates. MicroRNA regulation is the most abundant mode of post-transcriptional gene regulation. MicroRNAs that are involved in the initiation and progression of cancers are termed oncomiRs, several of which have been identified in canine and human cancer. Similarly, several miRNAs have been reported to be down-regulated in cancers of the two species. In this review, current information on the expression and roles of miRNAs in oncogenesis and the progression of human and canine cancer as well the roles miRNAs play in cancer stem cells’ biology is highlighted. The potential for miRNAs as therapeutic targets for personalized cancer therapy in domestic dogs and their possible application in human cancer counterparts are also discussed.
