Decorin and TGF-beta1 polymorphisms and development of COPD in a general population.

ABSTRACT:

Background

Decorin, an extracellular matrix (ECM) proteoglycan, and TGF-beta1 are both involved in lung ECM turnover. Decorin and TGF-beta1 expression are decreased respectively increased in COPD lung tissue. Interestingly, they act as each other's feedback regulator. We investigated whether single nucleotide polymorphisms (SNPs) in decorin and TGF-beta1 underlie accelerated decline in FEV1 and development of COPD in the general population.

Methods

We genotyped 1390 subjects from the Vlagtwedde/Vlaardingen cohort. Lung function was measured every 3 years for a period of 25 years. We tested whether five SNPs in decorin (3'UTR and four intron SNPs) and three SNPs in TGF-beta1 (3'UTR rs6957, C-509T rs1800469 and Leu10Pro rs1982073), and their haplotypes, were associated with CO
