pubmed:abstractText |
Endothelial dysfunction in diabetes is characterized by decreased nitric oxide (NO) bioactivity and increased superoxide (SO) production. Reduced levels of tetrahydrobiopterin (BH4), an essential cofactor of endothelial NO synthase (eNOS), appear to be associated with eNOS enzymatic uncoupling. We sought to investigate whether augmented BH4 biosynthesis in hyperglycemic human aortic endothelial cells (HAEC) by adenovirus-mediated gene transfer of GTP cyclohydrolase I (GTPCH, the rate-limiting enzyme for the de novo BH4 synthesis), would be sufficient to rescue eNOS activity and dimerization. HAEC were cultured in media with low glucose (5 mM) or high glucose (30 mM).
