TY - JOUR. T1 - Glucocorticoid regulation of phenylethanolamine N-methyltransferase (PNMT) in organ culture of superior cervical ganglia. AU - Bohn, M. C.. AU - Bloom, E.. AU - Goldstein, M.. AU - Black, I. B.. PY - 1984/9. Y1 - 1984/9. N2 - Glucocorticoid regulation of the adrenergic enzyme, phenylethanolamine N-methyltransferase (PNMT) was studied in organ cultures of the superior cervical ganglion (SCG) from newborn rats. Although PNMT catalytic activity was present in control ganglia, enzyme levels were too low to allow visualization of PNMT immunofluorescent cells. Addition of dexamethasone (DEX) or corticosterone to the medium resulted in a large increase in PNMT activity and bright PNMT immunoreactive (PNMT-IR) staining in cells resembling small, intensely fluorescent (SIF) cells. Addition of non-glucocorticoid steroids was ineffective. Exposure to a brief, 2-hr pulse of DEX (10-6 M) in vitro elicited the same increase in PNMT as continual exposure to DEX. Studies using metabolic ...

Expression of the noradrenaline transporter (NAT) was examined in normal human adrenal medulla and phaeochromocytoma by using immunohistochemistry and confocal microscopy. The enzymes tyrosine hydroxylase (TH) and phenylethanolamine N-methyltransferase (PNMT) were used as catecholamine biosynthetic markers and chromogranin A (CGA) as a marker for secretory granules. Catecholamine content was measured by using high performance liquid chromatography (HPLC). In normal human adrenal medulla (n=5), all chromaffin cells demonstrated strong TH, PNMT and NAT immunoreactivity. NAT was co-localized with PNMT and was located within the cytoplasm with a punctate appearance. Human phaeochromocytomas demonstrated strong TH expression (n=20 samples tested) but variable NAT and PNMT expression (n=24). NAT immunoreactivity ranged from absent (n=3) to weak (n=10) and strong (n=11) and, in some cases, occupied an apparent nuclear location. Unlike the expression seen in normal human adrenal medullary tissue, NAT ...

Objective: Social isolation is regarded as one of the most relevant causes of diseases in mammalian species. The activation of the sympathoneural system represents one of the key components of the stress response. The sympathetic nervous system is one of the major pathways involved in immune-neuroendocrine interactions. The aim of the present study was to determine plasma epinephrine and norepinephrine in individually housed rats, as well as to find out whether splenic gene expression of catecholamine synthesizing enzymes and their protein levels are affected by chronic psychosocial stress. Methods: Tyrosine hydroxylase (TH), dopamine-beta-hydroxylase (DBH) and phenylethanolamine N-methyltransferase (PNMT) mRNA levels were quantified by quantitative real-time RT-PCR. The TH, DBH and PNMT immunoproteins were assayed by Western blot. Results: Chronic social isolation of adult male rats produced a significant increase in plasma catecholamine levels and a decrease in splenic TH mRNA, DBH m...RNA and ...

Adrenergic cell group C1 is a group of cells that show evidence of phenylethanolamine N-methyltransferase (PNMT), the enzyme that converts norepinephrine to epinephrine (adrenalin); thus, they are regarded as putative adrenergic cells. They are found in the ventrolateral medulla in conjunction with the noradrenergic cell group A1. The adrenergic group C1 is seen in vertebrates, including rodents and primates.

In the present study, channelrhodopsin 2 (ChR2) was specifically introduced into murine cells expressing the Phenylethanolamine n-methyltransferase (Pnmt) gene, which encodes for the enzyme responsible for conversion of noradrenaline to adrenaline. The new murine model enabled the identification of a distinctive class of Pnmt-expressing neuroendocrine cells and their descendants (i.e. Pnmt+ cell derived cells) within the heart. Here, we show that Pnmt+ cells predominantly localized to the left side of the adult heart. Remarkably, many of the Pnmt+ cells in the left atrium and ventricle appeared to be working cardiomyocytes based on their morphological appearance and functional properties. These Pnmt+ cell derived cardiomyocytes (PdCMs) are similar to conventional myocytes in morphological, electrical and contractile properties. By stimulating PdCMs selectively with blue light, we were able to control cardiac rhythm in the whole heart, isolated tissue preparations and single cardiomyocytes. Our new

TY - JOUR. T1 - Catecholaminergic horizontal and amacrine cells in the ferret retina. AU - Keyser, K. T.. AU - Karten, H. J.. AU - Katz, Barrett. AU - Bohn, M. C.. PY - 1987. Y1 - 1987. N2 - Enzymes involved in the synthesis of catecholamines were detected in amacrine and what appeared to be a specific class of horizontal cells in the ferret retina. Antisera directed against the enzymes tyrosine hydroxylase (TH), which converts tyrosine to DOPA, and phenylethanolamine N-methyltransferase (PNMT), which converts norepinephrine to epinephrine, were used with conventional immunohistochemical techniques. A population of perikarya located at the outer margin of the inner nuclear layer (INL) exhibited TH-like immunoreactivity. The cell bodies were 9-12 μm in diameter and gave rise to stout dendrites that tapered rapidly after emergence from the somata. The processes formed a planar array in the inner half of the outer plexiform layer (OPL) slightly external to the cells of origin. We could not detect ...

Phenylethanolamine (sometimes abbreviated PEOH), or β-hydroxyphenethylamine, is a trace amine with a structure similar to those of other trace phenethylamines as well as the catecholamine neurotransmitters dopamine, norepinephrine, and epinephrine. As an organic compound, phenylethanolamine is a β-hydroxylated phenethylamine that is also structurally related to a number of synthetic drugs in the substituted phenethylamine class. In common with these compounds, phenylethanolamine has strong cardiovascular activity and, under the name Apophedrin, has been used as a drug to produce topical vasoconstriction ...

The catecholamines epinephrine and norepinephrine play critical roles in the maintenance of cardiovascular function. Phenylethanolamine-N-methyltransferase (Pnmt) catalyzes the conversion of norepinephrine to epinephrine and serves as a marker for adrenergic cells. We have previously shown that the selective destruction of Pnmt+ cells in the mouse produces severe left-ventricular dysfunction under anesthesia and that epinephrine deficiency alone does not recapitulate the phenotype. Here, we test the hypothesis that Pnmt+ cells are key modulators of the stress response to immobilization. Using a suicide reporter mouse model to ablate Pnmt+ cells (Pnmt-Cre/DTA), we achieve greater than 50% Pnmt+ cell reduction in the adrenal medulla and 97% reduction in Pnmt transcript. Remarkably, Pnmt+ cell destruction does not markedly diminish the cardiovascular response to restraint stress. At one hour of immobilization, heart rate and ejection fraction showed a similar increase in response to restraint in ...

Primary cultures of bovine adrenal chromaffin cells provide large quantities of a homogeneous population of target cells for nerve growth factor (NGF) and, thus, are a suitable system for studying the molecular mechanism of action of NGF. In this study, we have shown that NGF mediates the specific induction of the key enzymes in catecholamine biosynthesis, tyrosine hydroxylase (TH), dopamine-beta-hydroxylase (DBH), and phenylethanolamine-N-methyltransferase (PNMT). Acetylcholinesterase (AChE), an enzyme which catalyzes the breakdown of acetylcholine, is also induced by NGF. We have compared NGF-mediated TH and AChE induction and have provided pharmacological evidence that TH induction involves a post-transcriptional, polyadenylation-dependent event (blockable by 9-beta-arabinofuranosyladenine but not by alpha- amanitin), whereas AChE induction requires transcription (blockable by alpha-amanitin). DBH and PNMT appear to be regulated via the same mechanism as TH. The time course of TH induction is ...

Halostachine (also known as N-methylphenylethanolamine) is a natural product, an alkaloid first isolated from the Asian shrub Halostachys caspica (synonym Halostachys belangeriana), and structurally a β-hydroxy-phenethylamine (a phenylethanolamine) related to its better-known parent biogenic amine, phenylethanolamine, to the adrenergic drug synephrine, and to the alkaloid ephedrine. The pharmacological properties of halostachine have some similarity to those of these structurally-related compounds, and Halostachys caspica extracts have been included as a constituent of certain OTC dietary supplements, but halostachine has never been developed as a prescription drug. Although it is found in nature as a single stereoisomer, halostachine is more commonly available as a synthetic product in the form of its racemate (see below). In appearance it is a colorless solid. Naturally-occurring halostachine was first discovered by Syrneva in the halophytic plant Halostachys caspica (now classed as ...

Phenylethanolamine-N-methyltransferase (PNMT)-containing neurons in the rostral ventrolateral medulla (RVLM) are believed to play a role in cardiovascular regulation. To determine whether injection of anti-dopamine beta-hydroxylase (DbetaH)-saporin directly into the RVLM in rats could selectively destroy these cells and thereby provide an approach for evaluating their role in cardiovascular regulation, we studied rats 2 wk after unilateral injection of 21 ng anti-DbetaH-saporin into the RVLM. There was an approximately 90% reduction in the number of PNMT-positive neurons in the RVLM, although the number of non-C1, spinally projecting barosensitive neurons of this area was not altered. The A5 cell group was the only other population of DbetaH-containing cells that was significantly depleted. The depressor response evoked by injection of tyramine into the RVLM was abolished by prior injection of toxin. The pressor response evoked by injection of glutamate into the RVLM was attenuated ipsilateral to the

Background: Both catecholamines and δ-opioid receptor (DOR) agonists exert infarct-size-limiting effect against ischemia via the same final signaling pathways. We hypothesized that DOR-initiated cardioprotection is dependent on adrenergic activation via intrinsic cardiac adrenergic (ICA) cells, a newly identified cardiac neuroendocrine system.. Methods and Results: Using immunofluorescent double labeling coupled with in situ hybridization, we have detected tyrosine hydroxylase (TH) mRNA, the gene for rate-limiting catecholamine-forming enzyme in human ventricular ICA cells. We have colocalized the immunoreactivity of TH and DOR to the ICA cells in human and rat hearts. No TH mRNA or DOR immunoreactivity was identified in ventricular myocytes or sympathetic nerve endings. The physiological significance of DOR expression was examined by determining changes of cytosolic [Ca2+]i transients in fura-2-loaded isolated rat ICA cells using a fluorescence spectrophotometer. Application of a DOR agonist ...

The transgenic strategy applied in the current study may have several limitations. Expression of the Dbh-transgene may not be restricted to adrenergic cells (Mercer et al., 1991; Hoyle et al., 1994). However, mRNA expression of the Dbh-α2A-transgene was 26- to 169-fold lower in nonadrenergic regions of the CNS than in adrenergic nuclei, including locus ceruleus or sympathetic ganglia (Fig. 1d). Misexpression of α2A-receptors under the control of the Dbh promoter used for the present study may lead to false-positive assignments of α2-functions as autoreceptor (i.e., receptors in adrenergic cells). Furthermore, higher-than-physiological levels of α2A-receptor expression may result in a gain of function that is not achieved by endogenously expressed receptors. Indeed, we observed that transgenic α2A-receptors compensated for the loss of both α2A and α2C in sympathetic ganglia (Fig. 4b). Finally, α2A-adrenoceptors expressed under control of the Dbh promoter may alter their expression pattern ...

Background: Calcitonin gene-related peptide (CGRP) is a neuropeptide with broad salutary cardiovascular effects. Mechanisms underlying cardiac CGRP regulation are poorly understood. The intrinsic cardiac adrenergic (ICA) cell is a novel cardiac neuroendocrine cell that expresses the δ-opioid receptor. We have shown that δ-opioid stimulation of ICA cells induces epinephrine liberation exerting an infarct-size limiting effect via β2-adrenoreceptor (β2-AR) stimulation. In this study we hypothesize that ICA cells synthesize and release CGRP which is involved in myocardial function and that CGRP gene expression can be autoregulated by epinephrine released from the ICA cell or regulated exogenously via β2-AR agonist.. Methods and Results: In situ hybridization coupled with immunofluorescent double labeling localized CGRP mRNA expression exclusively to ICA cells in explanted human left ventricular tissue. To determine whether δ-opioid-enhanced epinephrine release from ICA cells autoregulates CGRP ...

Mycobacterial lipids have long been known to modulate the function of a variety of cells of the innate immune system. Here, we report the extraction and characterisation of polar and apolar free lipids from Mycobacterium bovis AF 2122/97 and identify the major lipids present in these fractions. Lipids found included trehalose dimycolate (TDM) and trehalose monomycolate (TMM), the apolar phthiocerol dimycocersates (PDIMs), triacyl glycerol (TAG), pentacyl trehalose (PAT), phenolic glycolipid (PGL), and mono-mycolyl glycerol (MMG). Polar lipids identified included glucose monomycolate (GMM), diphosphatidyl glycerol (DPG), phenylethanolamine (PE) and a range of mono- and di-acylated phosphatidyl inositol mannosides (PIMs). These lipid fractions are capable of altering the cytokine profile produced by fresh and cultured bovine monocytes as well as monocyte derived dendritic cells. Significant increases in the production of IL-10, IL-12, MIP-1β, TNFα and IL-6 were seen after exposure of antigen ...

The biosynthetic pathway of caffeine (1,3,7 Trimethylxanthine) starts with xanthosine, which is a natural component of the purine metabolism of all organisms. Necessary for its production are three distinct N-methyl transferases and one nucleosidase. However, it remains to be elucidated whether the nucleosidase reaction is catalyzed by an unspecific purine nucleoside phosphorylase (PNP) or by the first N-methyl transferase of the reaction cascade shown in the picture (Fig. 1). Being involved in the catabolism of all purine nucleosides, PNP is an essential enzyme for organisms and was shown to catalyze the removal of the ribose moiety of 7-methylxanthine in in vitro caffeine biosynthesis [Uefuji et al., 2003]. The in vivo synthesis of caffeine has also been shown by expression of the three N-methyl transferases in tobacco plants. Therefore, the assumption that the first methyl transferase is bifunctional and catalyzes the nucleosidase reaction is favored [Ashihara et al., 2008], [McCarthy and ...
