ABSTRACT: Background
Fibroblast dysfunction is the main pathogenic mechanism underpinning idiopathic pulmonary fibrosis (IPF). Potassium voltage-gated channel subfamily J member 2 (KCNJ2) plays critical roles in the proliferation of myofibroblasts and in the development of cardiac fibrosis.Objectives
This study aimed to evaluate the role of KCNJ2 in IPF.Methods
KCNJ2 mRNA expression was measured using real-time PCR in fibroblasts from IPF patients and normal controls (NCs). Protein concentrations were measured by ELISA in bronchoalveolar lavage (BAL) fluid obtained from NCs (n = 30), IPF (n = 30), IPF (n = 30), IPF (n = 30), IPF (n = 30), IPF (.Results
KCNJ2 mRNA expression was measured using real-time PCR in fibroblasts from IPF patients and normal controls (NCs). Protein concentrations were measured by ELISA in bronchoalveolar lavage (BAL) fluid obtained from NCs (n = 30), IPF (n = 30), IPF (p < 0.001). KCNJ2 protein levels in BAL fluid were significantly higher in IPF (6.587 [1.441-26.01] ng/mL) than in NCs (0.084 [0.00-0.260] ng/mL, p < 0.001). KCNJ2 protein levels in BAL fluid were significantly higher in IPF (6.587 [1.441-26.01] ng/mL) than in NCs (0.084 [0.00-0.260] ng/mL, p < 0.001). KCNJ2 protein levels in BAL fluid were significantly higher in IPF (6.587 [1.441-26.01] ng/mL) than in NCs (0.084 [0.00-0.260] ng/mL, p < 0.001). KCNJ2 protein levels in BAL fluid were significantly higher in IPF (6.587 [1.441-26.01] ng/mL) than in NCs (0.084 [0.00-0.260] ng/mL, p < 0.001). KCNJ2 protein levels in BAL fluid were significantly higher in IPF (6.587 [1.441-26.01] ng/mL) than in NCs (0.084 [0.00-0.260] ng/mL.Conclusion
KCNJ2 may participate in the development of IPF, and its protein level may be a candidate diagnostic and therapeutic molecule for IPF.
