In order to increase the tissue level of tetrahydrobiopterin (BH4 ) , supplementation with 6R-tetrahydrobiopterin (6RBH4) has been widely employed. In this work, the profile of BH4 accumulation was compared between the liver and the small intestine a

Tetrahydrobiopterin (BH4) was released from PC 12 cells to the extracellular fluid. We found that the BH4 outward flow from the cells placed in Hanks medium was increased when NaCl concentration of the medium was decreased. Increase in the BH4 out fl

A new function of tetrahydrobiopterin (BH4) was demonstrated in vitro in which BH4 stimulated serotonergic cells to release serotonin (5HT). RBL2H3 cells were pre-loaded with serotonin at 100 μM for 6 hours. The cells were able to release serotonin

The intracellular actlvlty of tryptophan hydroxylase was assessed by applying NSD-1055, an inhibitor of aromatic L-amino acid decarboxylase, to a monolayer culture of RBL2H3 cells from a serotonin producing rat basophilic leukemia cell line. Tryptoph

Cellular uptake of sepiapterin and tetrahydrobiopterin was compared quantitatively with RBL2H3 cells in culture. RBL2H3 is a mast cell line and has the ability to synthesize serotonin. Sepiapterin was incorporated and converted into tetrahydrobiopter
