Abstract

In spite of advances in the diagnosis and current molecular target therapies of lung cancer, this disease remains the most common cause of cancer-related death worldwide. Approximately 80% of lung cancers is non-small cell lung cancer (NSCLC), and 5-year survival rate of the disease is ~20%. On the other hand, idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease of unknown etiology. IPF is refractory to treatment and has a very low survival rate. Moreover, IPF is frequently associated with lung cancer. However, the common mechanisms shared by these two diseases remain poorly understood. In the post-genome sequence era, the discovery of noncoding RNAs, particularly microRNAs (miRNAs), has had a major impact on most biomedical fields, and these small molecules have been shown to contribute to the pathogenesis of NSCLC and IPF. Investigation of novel RNA networks mediated by miRNAs has improved our understanding of the molecular mechanisms of these diseases. This review summarizes our current knowledge on aberrantly expressed miRNAs regulating NSCLC and IPF based on miRNA expression signatures.
