microRNAs regulate gene expression primarily by inhibiting the mRNA translation of target genes. The expression of many miRNAs has been shown to be deregulated in cancer and to play a role in cancer progression. With respect to lung cancer in general and non-small cell lung cancer in particular, deregulated expression of miRNA is being used as an early detection system.
