The I(2) subgroup of imidazoline-binding sites was identified as monoamine oxidases (MAOs), but it is unclear whether there are I(2)-binding sites located on proteins distinct from MAOs. To address this issue, we characterized I(2)-binding proteins in liver and brain of wild-type and MAO A- and MAO B-deficient mice. I(2)-binding sites were identified using(More)
A cDNA library was prepared from quiescent guinea-pig endometrial glandular epithelial cells stimulated for 2 h with estradiol-17 beta (E2) in the presence of cycloheximide. It was screened by differential hybridization for estrogen-regulated sequences. Six recombinants containing E2-regulated sequences were identified. One of them, called gec1 was then(More)
In the present study, we investigated the existence of a back-regulation of the catecholamine-degrading enzyme monoamine oxidase (MAO)-A by dopamine in rat renal cells. In proximal tubule cells, MAO-A expression was not modified after dopamine receptor stimulation. In contrast, in mesangial cells, enzyme assay and Western blots showed that MAO activity and(More)
Glandular epithelial (GE) and stromal cells were isolated from guinea-pig endometrium, cultured and subcultured separately. At the end of subculture, the purity of each cell population was higher than 95% and cells displayed a high level of estrogen receptors. Calcium phosphate transfection conditions were defined using a control plasmid containing the(More)
The c-fos expression was investigated in primary culture of guinea pig glandular epithelial cells. These cells were made quiescent by serum deprivation and stimulated with fetal calf serum (FCS, 15%), 17 beta-estradiol (E2 10(-8) mol/l) alone or in combination with epidermal growth factor (EGF, 100 ng/ml) and insulin (I, 10 micrograms/ml). Low levels of(More)
