20351752 homozygous individuals for the TT haplotype were less likely to respond to the SSRI fluoxetine than to the nortriptyline suggesting a biological process through which GCHFR promoter variants might influence antidepressant response.
20351752 Observational study of gene-disease association, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
19926872 Studies provide a new mechanism for regulation of endothelial GTPCH-1 by its phosphorylation and interplay with GFRP.
19913121 Observational study of gene-disease association. (HuGE Navigator)

19101819 6BH(4) de novo synthesis is controlled by H(2)O(2) in a concentration-dependent manner, but H(2)O(2)-mediated oxidation does not affect the functionality of the GTPCHI/GFRP complex.
18372436 Demonstrate role for GFRP in regulating iNOS-mediated NO synthesis and suggest that the allosteric regulation of GTP-CH1 activity by GFRP may be an important mechanism regulating BH(4) and NO levels in vivo.
17135716 The co-expression of GTP cyclohydrolase I (GCHI) with tyrosine hydroxylase (TH) indicates that TH is indeed active in human neurosecretory neurons.
17101830 GCH1 mutations in Japanese patients with DYT5 dystonia. In some of them, the GCH1 enzyme activity was proved to be impaired.
