MicroRNAs (miRNAs) are a class of small single-stranded non-protein-coding RNAs that play important regulatory roles in many cellular processes including cell proliferation, differentiation, growth control, and apoptosis. They regulate gene expression on the posttranscriptional level by translational repression, mRNA cleavage, or mRNA degradation in various physiological and pathological processes. In addition, some miRNAs can function as oncogenes or tumor suppressors, so they can regulate several genes that play important roles in tumorigenesis. It was found that miRNAs are directly involved in many types of cancer, including lung cancer. Lung cancer is the leading cause of cancer mortality worldwide with a substantially low survival rate. In this work, we summarize recent findings related to miRNAs mechanisms of action and the role of their dysregulated expression in lung tumorigenesis. We describe the most important miRNAs involved in lung cancer development and targets of their activity. The understanding of the miRNA regulation in cancer may help better understand the molecular mechanisms of tumorigenesis and their importance in cancerous transformation. |
