Figure 2 Effect of GCH1 Haplotype on Vascular GTPCH mRNA Levels

The presence of the XX genotype was associated with significantly lower messenger ribonucleic acid (mRNA) levels of GTPCH compared with OO genotype. Shown are the data derived from 23 saphenous veins (SVs) and 17 internal mammary arteries (IMAs). *p < 0.05 versus OO.
