Chronic inflammatory diseases of the lung are often life-threatening and are a leading cause of morbidity in our communities. MicroRNAs (miRs) are now recognized to play critical roles in a wide range of cellular functions, including the regulation of immunologic processes, which are often dysregulated in chronic respiratory diseases. These small noncoding RNA molecules regulate networks of genes by inhibiting translation through the targeting of one or multiple messenger RNA transcripts. This review highlights discoveries that identify important roles for miRs in the regulation of specific pathogenic features of a range of diseases. Furthermore, experimental evidence suggests that pharmacologic inhibition of miR function or delivery of mimics may have therapeutic potential. The review also therefore discusses the potential utility and limitations of therapeutically targeting these molecules and their downstream pathways.

Lung cancer is the primary cause of cancer-related deaths. Most patients are typically diagnosed at advanced stages. Low-dose computed tomography (LDCT) has been proven to reduce lung cancer mortality, but screening programs using LDCT are associated with a high number of false positives and unnecessary thoracotomies.

Pulmonary hypertension associated with lung diseases and/or hypoxia is classified as group 3 in the clinical classification of pulmonary hypertension. The efficacy of existing selective pulmonary vasodilators for group 3 pulmonary hypertension is still unknown, and it is currently associated with a poor prognosis. The mechanisms by which pulmonary hypertension occurs include hypoxic pulmonary vasoconstriction, pulmonary vascular remodeling, a decrease in pulmonary vascular beds, endothelial dysfunction, endothelial-to-mesenchymal transition, mitochondrial dysfunction, oxidative stress, hypoxia-inducible factors (HIFs), inflammation, microRNA, and genetic predisposition.

Background: MicroRNAs (miRNAs) are crucial post-transcriptional regulators involved in inflammatory diseases, such as asthma. Poor lung function and airflow issues in childhood are linked to the development of chronic obstructive pulmonary disease (COPD) in adulthood.
Methods: We analyzed small RNA-Seq data from 365 peripheral whole blood samples from the Genetics of Asthma in Costa Rica Study (GACRS) for association with airflow levels measured by FEV1/FVC.
