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 کاملActivation of human histidine decarboxylase gene promoter activity by gastrin is mediated by two distinct nuclear factors.
The human histidine decarboxylase gene is regulated by gastrin through a cis-acting element known as the gastrin response element (GAS-RE) that was initially localized to a site (+2 to +24) downstream of the transcriptional start site. Electrophoretic mobility shift assays using sequentially deleted DNA probes and nuclear extracts from AGS-B gastric cancer cells showed that the GAS-RE is actual...
متن کاملVascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms
Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
متن کاملImmunolocalization of gastrin-dependent histidine decarboxylase activity in rat gastric mucosa during feeding.
The localization of histidine decarboxylase (HDC) activity in the enterochromaffin-like (ECL) cells of the oxyntic mucosa was studied during fasting and refeeding using monoclonal (CURE no. 44178) and polyclonal (CURE no. 94211) antibodies directed against the COOH terminus of HDC (HDC-CT). Changes in HDC immunostaining were correlated with mucosal HDC enzyme activity. Immunoneutralization of c...
متن کاملControl of histidine decarboxylase gene expression in enterochromaffin-like cells.
The ability of histamine to stimulate gastric acid secretion was recognized over 75 years ago by Popielski [1]. The central importance of this action in the physiological regulation of acid secretion was established with the development of histamine H2 receptor antagonists by Black and colleagues in the early 1970s [2]. There has, however, been intense debate about the precise mechanisms of act...
