Arterial stiffness is a risk factor for cardiovascular disease. Transforming growth factor beta1 is a pleiotropic cytokine, with many functions, including influence on the vascular wall (e.g., on angiogenesis, endothelial cells and the extracellular matrix). We investigated five functional polymorphisms in the transforming growth factor beta1 gene (-800 G/A, -509 C/T, codon 10 Leu/Pro, codon 25 Arg/Pro and codon 263 Thr/Ile) in relation to arterial stiffness in a population-based study. A total of 3863 participants of the Rotterdam Study, a prospective population-based study, were included in the current study. The relations of the genotypes and haplotypes with arterial stiffness (pulse wave velocity (PWV), distensibility coefficient (DC) and pulse pressure (PP)) were studied using analyses of variance and linear regression. The analyses were adjusted for age, sex, mean arterial pressure, heart rate, conventional cardiovascular risk factors and measures of atherosclerosis. There were no associations between PWV and -800 G/A (P=0.56), -509 C/T (P=0.29), codon 10 (P=0.98) and, codon 25 (P=0.28). These polymorphisms were not associated with the DC or with PP. The haplotype-based analyses yielded similar results. The results of this study show that the TGF-beta1 -800 G/A, -509 C/T, codon 10 Leu/Pro and codon 25 Arg/Pro polymorphisms are not associated with arterial stiffness.
