MicroRNAs in the lung

Adv Exp Med Biol. 2013;774:121-34. doi: 10.1007/978-94-007-5590-1_7.


The lung constitutes one of the most delicate tissue structures in mammalian organisms to accomplish the vital function of gas exchange. On the other hand, its immense surface area, necessary in this context, exhibits the first line of defense against a variety of pro-inflammatory stimuli.MicroRNAs (miRNAs) are a class of post-transcriptional regulators that revolutionized our view of gene expression regulation. By now, it is well established that miRNAs impair all known cellular and developmental processes. Extensive research over the last years revealed not only a fundamental role for miRNAs in lung development and homeostasis, but also in the process of lung inflammation. Lung inflammation occurs in response to stimuli very different in nature (e.g., physical, radioactive, infective, pro-allergenic, or toxic), and in some cases becomes manifest in chronic diseases (e.g., chronic bronchitis/chronic obstructive pulmonary disease (COPD), asthma and allergic airway diseases) or even lung cancer.This review chapter will briefly describe the current knowledge concerning miRNA expression and their exerted target regulation in the course of lung inflammation and lung cancer.
