Abstract

MicroRNAs (miRNAs) are small, non-coding RNA species that are highly evolutionarily conserved, from higher invertebrates to man. Up to 1000 miRNAs have been identified in human cells thus far, where they are key regulators of the expression of numerous targets at the post-transcriptional level. They are implicated in various processes, including cell differentiation, metabolism, and inflammation. miRNA biogenesis involves the stepwise processing of a precursor primary miRNA (pri-miRNA) molecule by the nuclear RNase III Drosha and the cytosolic RNase III Dicer that eventually results in the incorporation of the so-called “guide strand” deriving from a transitory intermediate RNA duplex into the macromolecular RNA-induced silencing complex (RISC) which silences gene expression through hindering the translation of its mRNA target(s). An expanding list of miRNAs is known to be involved in the pathogenesis of common, non-autoimmune inflammatory diseases. Interestingly, osteoarthritis (OA) is now being conceptualized as a metabolic disease, as there is a correlation among hyperuricemia and metabolic syndrome (MetS). Experimental evidence suggests that metabolic deregulation is a commonality between these different pathological entities, and that miRNAs are key players in the modulation of metabolic routes. In light of these findings, this review discusses the role of miRNAs in OA and gouty arthritis, as well as the possible therapeutic targetability of miRNAs in these diseases.
