Abstract

Multiple intracellular and extracellular regulatory factors affect transcription of the tyrosine hydroxylase (TH) gene encoding the rate-limiting enzyme in the biosynthesis of the neurotransmitters dopamine, norepinephrine and epinephrine. Short chain fatty acids like butyrate are known to alter TH gene expression, but the mechanism of action is unknown. In this report, transient transfection assays identified the proximal TH promoter to contain sufficient genetic information to confer butyrate responsiveness to a reporter gene. Deletion studies and gel shift analyses revealed that the promoter region spanning the cAMP response element is an absolute requirement for transcriptional activation by butyrate. The branched short chain fatty acid valproate is used for seizure control in humans. Significantly, it has a similar aliphatic structure to butyrate, and it was found to have similar effects on TH in PC12 cells. Site-directed mutagenesis indicated that the effects of both fatty acids were mediated through the canonical CRE. Butyrate treatment also resulted in CREB phosphorylation without changing CREB protein levels. The increased phosphorylation of CREB correlated with accumulation of TH mRNA. The adenylate cyclase inhibitor dideoxyadenosine blocked both CREB phosphorylation and accumulation of TH mRNA. The data are consistent with the conclusion that butyrate induces post-translational modifications of pre-existing CREB molecules in a cAMP/PKA-dependent manner to alter TH transcription. These results support the role of butyrate as a novel exogenous regulatory factor in TH gene expression. Our data delineate a molecular mechanism through which diet-derived environmental signals (e.g. butyrate) can modulate catecholaminergic systems by affecting TH gene transcription.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
