Effect of hydrocortisone on histidine decarboxylase activity in rat stomach.
Hydrocortisone-stimulated synthesis of histidine decarboxylase (EC 4.1.1.22) was studied in rat stomach. Single or daily administration of hydrocortisone increased the histidine decarboxylase activity but not the histamine content in the fundic glands of stomachs from fed and fasted rats with or without adrenalectomy, and also in those from adrenalectomized fasted rats with concomitant treatmen...
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 کاملSpectroscopic analysis of recombinant rat histidine decarboxylase.
Mammalian histidine decarboxylases have not been characterized well owing to their low amounts in tissues and instability. We describe here the first spectroscopic characterization of a mammalian histidine decarboxylase, i.e. a recombinant version of the rat enzyme purified from transformed Escherichia coli cultures, with similar kinetic constants to those reported for mammalian histidine decar...
متن کاملChanges in ornithine decarboxylase activity in rat intestines during aging.
The ornithine decarboxylase (ODC) activity of rat intestines, liver, and brain was found to vary dramatically as animals develop and age. Unusually high activity was present in the small intestines of adult animals. The ODC activity of the small intestines approximated that of fetal tissues and of regenerating rat liver. Putrescine, spermine, and spermidine levels of fetal and adult animal tiss...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
