MicroRnas profiling in asthma: potential biomarkers and therapeutic targets

Asthma is a heterogeneous chronic inflammatory disorder in which different endotypes contribute to define clinical-inflammatory phenotypes. MicroRNAs (miRNAs) are a group of minute, endogenous 22-25 nt RNA elements that join to particular mRNAs to reduce translation and increase mRNA degradation. miRNAs operate in post-transcriptional control and regulate physiological and pathological processes in several illnesses. The purpose of this work is to review and discuss the current knowledge on the function of miRNAs in asthma, focusing the attention particularly on their biological properties, pathophysiologic actions, and possible usage as markers and treatments for asthma.
