The regulation of histidine decarboxylase gene expression.
Histamine is a biogenic amine, which is involved in a variety of biologic processes comprising inflammation, allergic responses, neurotransmission and regulation of gastric acid secretion. The key enzyme for the generation of histamine is histidine decarboxylase (HDC), which converts the amino acid L-histidine to histamine. In this article, we review the history, biochemistry and molecular biol...
متن کاملHuman kininogen gene is transactivated by the farnesoid X receptor.
Human kininogen belongs to the plasma kallikreinkinin system. High molecular weight kininogen is the precursor for two-chain kinin-free kininogen and bradykinin. It has been shown that the two-chain kinin-free kininogen has the properties of anti-adhesion, anti-platelet aggregation, and anti-thrombosis, whereas bradykinin is a potent vasodilator and mediator of inflammation. In this study we sh...
متن کاملChapter 6 L - Histidine Decarboxylase A Marker of Histaminergic Neurons
The role of histamine (HA) as a neurotransmitter in the CNS, although proposed a decade ago (Schwartz, 1975), has been only progressively recognized (reviewed by Schwartz et al., 1980, 1982, 1984; Hough and Green, 1984). One of the key pieces of expenmental evidence has been the demonstration that synthesis of the amine in CNS depends on a specific enzyme, L-histidine decarboxylase (HDC) (Schwa...
متن کاملL-histidine decarboxylase decreases its own transcription through downregulation of ERK activity.
A poorly defined negative feedback loop decreases transcription of the L-histidine decarboxylase (HDC) gene. To help understand this regulation, we have studied the effect of HDC protein expression on HDC gene transcription in transfected AGS-B cells. Expression of the rat HDC protein inhibited HDC promoter activity in a dose-dependent fashion. The region of the HDC promoter mediating this inhi...
متن کاملMast cell-/basophil-specific transcriptional regulation of human L-histidine decarboxylase gene by CpG methylation in the promoter region.
L-Histidine decarboxylase (HDC) catalyzes the formation of histamine from L-histidine, and in hematopoietic cell lineages the gene is expressed only in mast cells and basophils. We attempted here to discover how HDC gene expression is restricted in these cells. In the cultured cell lines tested, only the mast cells and basophils strongly transcribed the HDC gene. However, in transient transfect...
