.... Together, two enzymes, tyrosine hydroxylase (TH,encoded by ple) and dopa decarboxylase (DDC, encoded by Ddc), produce the dopamine that is required for tanning. Levels of both the ple and Ddc transcripts begin to accumulate before eclosion, coincident with the onset of pigmentation of the pharate adult...

... chromaffin cells and sympathetic neurons. Additionally, mRNA analyses of purified chromaffin cells from Gata3 mutants show that levels of Mash1, Hand2 and Phox2b(postulated upstream regulators of Gata3) as well as terminally differentiated SA lineage products (tyrosine hydroxylase, Th, and dopamineβ...

...-catenin overexpression either alone or in association with RA express the caudal neuronal marker Hoxc4. However, RA treatment inhibits the β-catenin-mediated generation of tyrosine hydroxylase-positive neurons, suggesting that not all of the effects of RA are dependent upon β-catenin signaling...

... or the more generic process of neuronal differentiation itself. In gain-of-function experiments, Nurr1 is able to activate transcription of the tyrosine hydroxylase gene by binding a response element within a region of the tyrosine hydroxylase promoter necessary for midbrain-specific expression...

...Guoping Fan; David M. Katz ABSTRACT Although some sensory ganglion cells in mature animals are catecholaminergic, most mammalian sensory neurons that express the catecholamine-synthesizing enzyme tyrosine hydroxylase (TH) do so only transiently during early gangliogenesis in vivo. The lack of TH...

Tyrosine hydroxylase (TH)-immuno-reactive neurons developed in vitro in 4/12 such explants; therefore, cells...

... of enteric neuronal diversity, we examined the expression of serotonin (5-HT), tyrosine hydroxylase and GABA in vitro . In the mature avian intestine, intrinsic neurones contain 5- HT or GABA but not tyrosine hydroxylase. These markers were demonstrated immunocytochemically, singly or simultaneously. All...

Both total tyrosine hydroxylase activity and protein levels in sympathetic chains were reduced by about 30 % in embryos treated with 27/21 antibody but not in embryos treated with a control antibody. The 27/21 antibody cross-reacts with chick...
