Monoamine oxidase inhibitors (MAOI) have been widely used as antidepressants. Recently, there has been renewed interest in MAO inhibitors. The activity-guided fractionation of extracts from Angelica keiskei Koidzumi (A. keiskei K.) led to the isolation of two prenylated chalcones, xanthoangelol and 4-hydroxyderricin and a flavonoid, cynaroside. These three isolated compounds are the major activ...
Serum DBH activity in a normal population of 58 individuais shows a gaussian distribution, on the opposite to what happens in a popuiation of 100 diabetics. These two populations also differ statistically by the analysis of variance. However it was round that it is not possible to correiate ...rum DBH neither with insulin admi nistration, type of diabetes, duration of disease, nor with the seve...
Acorn production varies considerably among oak (Quercus) species, individual trees, years, and locations, which directly affects oak regeneration and populations of wildlife species that depend on acorns for food. Hard mast indices provide a relative ranking and basis for comparison of withinand between-year acorn crop size at a broad scale, but do not provide an estimate of actual acorn yield—...
In the present study, we determined the involvement of brainstem catecholaminergic inputs to the paraventricular nucleus (PVN) on estrogen receptor alpha (ERalpha) expression in this nucleus during conditions of 48-h fasting, 2-deoxy-d-glucose (2DG)-induced acute glucoprivation and 1-h immobilization, in ovariectomized rats. Our approach was to examine the effect of lesioning catecholaminergic ...
Nitric oxide (NO) regulates a wide range of physiological processes. Recent studies show that NO can regulate the release of catecholamines (CA) from the adrenal medulla. In the current study, the PC12 cell line was used to examine the effect of NO on the regulation of the CA biosynthetic enzymes: tyrosine hydroxylase (TH), dopamine-β-hydroxylase (DBH) and phenylethanolamine Nmethyltransferase ...
Depression is associated with increased risk of coronary heart diseases. Selective serotonin reuptake inhibitors (SSRIs) have been proved to be very effective in normalizing symptoms of depression, but the data on possible influence of these drugs on cardiovascular function is controversial. Applying Taqman RT-PCR assay, the effect of chronic treatment with a SSRI antidepressant fluoxetine has ...
The resistance of breast cancer to radiotherapy remains a major obstacle to successful cancer management. Radiotherapy may result in DNA damage and activate breast cancer stem cells. DNA damage may lead to activation of the checkpoint kinase (CHK) signaling pathway, of which debromohymenialdisine (DBH) is a specific inhibitor. Radiotherapy also increases the expression of phosphorylated CHK1/2 ...
In viva biosynthesis of the 2 subunit forms of dopamine B-hydroxylase (DBH) was examined in the rat brain. %-methionine was injected into the noradrenergic neurons of the locus coeruleus (LC) using a stereotactic device. Several hours later, newly synthesized 35S-Met-labeled DBH was immunoprecipitated and quantitated. Both M, = 77,000 (77K) and 73,000 (73K) subunit forms were present in near-eq...
