PG - 159-65 LID - 10.3892/mmr.2014.2763 [doi] AB - The present study aimed to investigate the effect of C-type natriuretic peptide (CNP) on the function of cardiac fibroblasts (CFs). Western blotting was used to investigate the expression of myofibroblast marker proteins: alpha-smooth muscle actin (alpha-SMA), extra domain-A fibronectin, collagen I and collagen III, and the activity of extracellular signal-regulated kinase 1/2 (ERK1/2). Immunofluorescence was used to examine the morphological changes; a transwell assay was used to analyze migration, and reverse transcription-quantitative polymerase chain reaction and ELISA were employed to determine the mRNA expression and protein secretion of monocyte chemoattractant protein-1 (MCP-1) and plasminogen activator inhibitor-1 (PAI-1). The results demonstrated that CNP significantly reduced the protein expression of alpha-SMA, fibronectin, collagen I and collagen III, and suppressed the migratory ability of CFs. Additionally, the mRNA and protein expression of MCP-1 and PAI-1 was inhibited under the CNP treatment; and this effect was mediated by the inhibition of the ERK1/2 activity. In conclusion, CNP inhibited cardiac fibroblast differentiation and migration, and reduced the secretion of MCP-1 and PAI-1, which demonstrates novel mechanisms to explain the antifibrotic effect of CNP.
