Cystic fibrosis (CF), a genetic disorder, is characterized by chronic lung disease. Small non‐coding RNAs are key regulators of gene expression and participate in various processes, which are dysregulated in CF; however, they remain poorly studied. Here, we determined the complete microRNAs (miRNAs) expression pattern in three CF ex vivo models. The miRNA profiles of air–liquid interface cultures of airway epithelia (bronchi, nasal cells, and nasal polyps) samples from patients with CF and non‐CF controls were obtained by deep sequencing. Compared with non‐CF controls, several miRNAs were deregulated in CF samples; for instance, miR‐181a‐5p and the miR‐449 family were upregulated. Moreover, mature miRNAs often showed variations (i.e. isomiRs) relative to their reference sequence, such as miR‐101, suggesting that miRNAs consist of heterogeneous repertoires of multiple isoforms with different effects on gene expression. Analysis of miR‐181a‐5p and miR‐101‐3p roles indicated that they regulate the expression of WISP1, a key component of cell proliferation/migration programs. We showed that miR‐101 and miR‐181a‐5p participated in aberrant recapitulation of wound healing programs by controlling WISP1 mRNA and protein level. Our miRNA expression data bring new insights into CF physiopathology and define new potential therapeutic targets in CF. © 2020 The Pathological Society of Great Britain and Ireland.
