Long Non-Coding RNA Review and Implications in Lung Diseases

Non-coding genes occupy the majority of the human genome and have recently garnered increased attention for their implications in a range of diseases. This review illustrates the current scientific landscape concerning long non-coding RNA biogenesis, regulation, and degradation, as well as their functional roles in lung pathogenesis. LncRNAs share many similar biogenesis and regulatory processes with mRNA, such as capping, polyadenylation, post-transcriptional modifications, and exonuclease degradation. Evidence suggests that these lncRNAs become dysregulated in lung diseases such as Acute Lung Injury, Idiopathic Pulmonary Fibrosis, COPD, Lung Cancer, and Pulmonary Arterial Fiypertension. Some lncRNAs have known functions, but the overwhelming majority requires further research to completely understand.
