The role of microRNAs in lung cancer progression.

Lung cancer is a heterogeneous disease with currently still unknown mechanisms of development. Besides genetic and epigenetic mechanisms, microRNAs (miRNAs) have recently been discovered as one of the crucial players in lung carcinogenesis through posttranscriptional regulation of tumor suppressor and oncogenes. A substantial number of deregulated miRNAs have been revealed in lung cancer, and the biological significance of those miRNAs has been confirmed in multiple functional experiments.
