Regulation of MUC5B expression in idiopathic pulmonary fibrosis
Idiopathic pulmonary fibrosis (IPF) is the most common and the most aggressive fibrosing interstitial lung disease (ILD). Despite recent promising clinical trials, IPF remains incurable and largely untreatable. Genetic studies have identified several risk loci for both sporadic and familial forms of IPF. A single variant upstream of MUC5B is predicted to account for more than 30% of all IPF risk. This variant, rs35705950, is associated with expression of MUC5B in healthy lung tissue. However, the mechanism underlying the relationship between rs35705950 and MUC5B expression remains unclear. ...
