Contribution of signaling pathways associated with cellular senescence and regulatory non-coding RNAs to chronic obstructive pulmonary disease

Abstract

Chronic obstructive pulmonary disease (COPD) is a multifactorial disease of the respiratory system that affects the lung parenchyma and airways; it is one of the leading causes of death in the world, which explains the constant search for new approaches to diagnosis, treatment and prevention of the disease. COPD develops as a result of a complex interaction of molecular genetic factors, a network of epigenetic regulators, and environmental factors that are closely related to lifestyle. The molecular pathogenesis of COPD may include the mechanisms of alteration of the regulation of stressful reactions that prevent cellular senescence. Non-coding RNAs play an important role in the regulation of various intracellular signaling pathways and is the most relevant subject of genetic studies of various pathological phenotypes. The expression profile of long non-coding RNA is often disregulated in various diseases. Information on the role of long non-coding RNA in the development of COPD is limited. Long non-coding RNA and the target-genes of signaling pathways involved in cellular senescence form a complex interactive network and may be targets for disease therapy. The review presents the data concerning some aspects of the molecular pathogenesis of COPD, as well as role of long non-coding RNAs in the development of the COPD.
