Nonethless, the dysregulation of miR-92a and its role in pulmonary fibrosis [17] has been extensively explained by Berschneider et al. The authors for the first time demonstrated the inverse correlation between the expression of miR-92a and WISP1 protein in idiopathic pulmonary fibrosis. This evidence concerns the gene CCN4 and idiopathic pulmonary fibrosis.
