VPS53 and idiopathic pulmonary fibrosis: In addition, five potential altered microRNA–mRNA interactions were found, including hsa-miR-939-5p–PLXNA4, hsa-miR-3918–CTIF, hsa-miR-4768-5p–PDE5A, hsa-miR-1273g-3p–VPS53, and hsa-miR-1972–PCSK9. In summary, differentially expressed genes and microRNAs in response to EGCG treatment in IPF fibroblasts were identified in the current study.
