[3H]-Mesulergine labels 5-HT7 sites in rat brain and guinea-pig ileum but not rat jejunum. (1/38)

1. The primary aim of this investigation was to determine whether binding sites corresponding to the 5-HT7 receptor could be detected in smooth muscle of the rat jejunum. Binding studies in rat brain (whole brain minus cerebellum) and guinea-pig ileal longitudinal muscle were also undertaken in order to compare the binding characteristics of these tissues. Studies were performed using [3H]-mesulergine, as it has a high affinity for 5-HT7 receptors. 2. In the rat brain and guinea-pig ileum, pKD values for [3H]-mesulergine of 8.0 +/- 0.04 and 7.9 +/- 0.11 (n = 3) and Bmax values of 9.9 +/- 0.3 and 21.5 +/- 4.9 fmol mg(-1) protein were obtained respectively, but no binding was detected in the rat jejunum. [3H]-mesulergine binding in the rat brain and guinea-pig ileum was displaced with the agonists 5-carboxamidotryptamine (5-CT) > 5-hydroxytryptamine (5-HT) > or = 5-methoxytryptamine (5-MeOT) > sumatriptan and the antagonists risperidone > or = LSD > or = metergoline > ritanserin > > pindolol. 3. Despite the lack of [3H]-mesulergine binding in the rat jejunum, functional studies undertaken revealed a biphasic contractile response to 5-HT which was partly blocked by ondansetron (1 microM). The residual response was present in over 50% of tissues studied and was found to be inhibited by risperidone > LSD > metergoline > mesulergine = ritanserin > pindolol, but was unaffected by RS 102221 (3 microM), cinanserin (30 nM), yohimbine (0.1 microM) and GR 113808 (1 microM). In addition, the agonist order of potency was 5-CT > 5-HT > 5-MeOT > sumatriptan. 4. In conclusion, binding studies performed with [3H]-mesulergine were able to detect 5-HT7 sites in rat brain and guinea-pig ileum, but not in rat jejunum, where a functional 5-HT7-like receptor was present.  (+info)

Discriminative stimulus properties of indorenate, a serotonin agonist. (2/38)

OBJECTIVE: To determine whether indorenate, a serotonin-receptor agonist, can exert discriminative control over operant responses, to establish the temporal course of discriminative control and to compare its stimulus properties to a (5-HT)IA receptor agonist. [3H]-8-hydroxy-2-(di-N-propylamino) tetralin (8-OH-DPAT). DESIGN: Prospective animal study. ANIMALS: Ten male Wistar rats. INTERVENTIONS: Rats were trained to press either of 2 levers for sucrose solution according to a fixed ratio schedule, which was gradually increased. Rats were given injections of either indorenate or saline solution during discrimination training. Once they had achieved an 83% accuracy rate, rats underwent generalization tests after having received a different dose of indorenate, the training dose of indorenate at various intervals before the test, various doses of 8-OH-DPT, or NAN-190 administered before indorenate or 8-OH-DPAT. OUTCOME MEASURES: Distribution of responses between the 2 levers before the first reinforcer of the session, response rate for all the responses in the session, and a discrimination index that expressed the drug-appropriate responses as a proportion of the total responses. RESULTS: Indorenate administration resulted in discriminative control over operant responses, maintained at fixed ratio 10, at a dose of 10.0 mg/kg (but not 3.0 mg/kg). When the interval between the administration of indorenate and the start of the session was varied, the time course of its cue properties followed that of its described effects on 5-HT turnover. In generalization tests, the discrimination index was a function of the dose of indorenate employed; moreover, administration of 8-OH-DPAT (from 0.1 to 1.0 mg/kg) fully mimicked the stimulus properties of indorenate in a dose-dependent way. The (5-HT)IA antagonist NAN-190 prevented the stimulus generalization from indorenate to 8-OH-DPAT. Also, NAN-190 antagonized the stimulus control of indorenate when administered 45 minutes before the session, but not when administered 105 minutes before the session (i.e., 15 minutes before the administration of indorenate). CONCLUSION: (5-HT)IA receptors are of relevance to the stimulus function of indorenate. However, other receptor subtypes may also be involved. Hence, other agonists and specific antagonists should be studied before definite conclusions are drawn.  (+info)

Pharmacological characterization of 5-HT4 receptors mediating relaxation of canine isolated rectum circular smooth muscle. (3/38)

This study aimed to characterize for the first time in vitro 5-HT4 receptors in the canine gastrointestinal tract. For this purpose, we used circular muscle strips of the canine isolated rectum. In the presence of methysergide (60 microM), 5-HT induced relaxation of methacholine (1 microM)-precontracted muscle strips, yielding a monophasic sigmoidal concentration-relaxation curve (pEC50 7.2+/-0.07). Tetrodotoxin (0.3 microM) did not affect the curve to 5-HT, suggesting the inhibitory 5-HT receptor is located on the smooth muscle. Granisetron (0.3 microM) did also not affect the curve to 5-HT, which excludes the 5-HT3 receptor mediating the relaxation to 5-HT. The presence of methysergide rules out the involvement of 5-HT1, 5-HT2 or 5-HT7 receptors. 5-HT, the selective 5-HT4 receptor agonists R076186, prucalopride (R093877) and SDZ HTF-919 and the 5-HT4 receptor agonists cisapride and 5-MeOT relaxed the muscle strips with a rank order of potency R076186 = 5-HT > cisapride > prucalopride > or = SDZ HTF-919 > 5-MeOT. The selective 5-HT4 receptor antagonists GR 125487, RS 39604 and GR 113808 competitively antagonized the relaxations to 5-HT, yielding pK(B) estimates of 9.7, 7.9 and 9.1, respectively. The selective 5-HT4 receptor antagonist SB 204070 shifted the curve to 5-HT rightward and depressed the maximal response (apparent pA2 10.6). GR 113808 (10 nM) produced a parallel rightward shift of the curve to the selective 5-HT4 receptor agonists R076186 (pA2 8.8). It is concluded that 5-HT induces relaxation of the canine rectum circular muscle through stimulation of a single population of smooth muscle 5-HT4 receptors. For the first time, a nonhuman species was shown to exhibit relaxant 5-HT4 receptors in the large intestine.  (+info)

5-HT(4) receptors in nucleus tractus solitarii attenuate cardiopulmonary reflex in anesthetized rats. (4/38)

We determined whether the cAMP-protein kinase A (PKA) pathway modulation of the cardiopulmonary reflex was caused by activation of 5-HT(4) receptors at the level of the nucleus tractus solitarii (NTS) of the anesthetized rat. NTS microinjection of 5-methoxytryptamine (5-MeOT, 2.25 pmol, n = 13), a 5-HT-receptor agonist, attenuated the cardiopulmonary reflex-evoked bradycardia and tachypnea. Microinjection of RS-39604 (4.5 pmol, n = 6), a selective 5-HT(4)-receptor antagonist, blocked the attenuating effect of 5-MeOT. NTS microinjection of 8-bromoadenosine 3', 5'-cyclic monophosphate (8-BrcAMP, 9 nmol, 45 nl, n = 10), a membrane-permeant analog of cAMP, significantly attenuated the reflex bradycardia and tachypnea. Rp-adenosine 3',5'-cyclic monophosphorothioate (4.5 nmol, n = 6), a cAMP-dependent PKA inhibitor, had no effect on the cardiopulmonary reflex when microinjected into the NTS alone but when given before a microinjection of either 8-BrcAMP (n = 6) or 5-MeOT (n = 6) blocked the attenuating effect on the reflex-evoked bradycardia. Thus stimulation of 5-HT(4) receptors within the NTS depresses the reflex bradycardia components of the cardiopulmonary reflex via a cAMP-dependent PKA pathway.  (+info)

Smooth muscle layer-dependent distribution of 5-hydroxytryptamine(7) receptor in the porcine myometrium. (5/38)

1. To analyse the mechanisms of muscle layer-dependent inhibition of porcine myometrial contractility by 5-hydroxytryptamine (5-HT), the effects of 5-HT, 5-carboxamidotryptamine(5-CT), 5-methoxytryptamine (5-MeOT), forskolin and cyclic adenosine 3', 5'-monophosphate (cyclic AMP) analogues on spontaneous and stimulant-induced contractions were examined in longitudinal (LM) and circular muscles (CM). In addition, accumulation of cyclic AMP by 5-HT and distribution of 5-HT(7) receptors in LM and CM layers were compared using biochemical and molecular approaches. 2. 5-HT receptor agonists inhibited the spontaneous contractions of LM and CM (5-CT>5-HT>5-MeOT), but CM was more sensitive than was LM. The inhibition by the agonists was antagonized by methiothepin (100 nM). 3. Carbachol-, high-K(+)-, histamine- and Ca(2+)-induced contractions were inhibited by 5-HT with different responses (CM>LM). Even in the presence of 3-isobutyl-1-methylxanthine (IBMX), the inhibition by 5-HT in the CM was still more conspicuous than that in the LM. 4. Compared with the CM, the inhibition of spontaneous contraction by forskolin, dibutyryl-cyclic AMP and 8-bromo-cyclic AMP was marked in the LM. 5. 5-HT (1 nM - 1 microM) increased the cyclic AMP in both muscle layers, but the increment in the CM was higher than that in the LM whether IBMX was present or not. 6. LM and CM layers contained a single class of [(3)H]-5-CT binding sites with a similar K(d) value (0.21 - 0.24 nM). However, B(max) (5-HT(7) receptor concentration) in the CM (120.6 fmol mg(-1) protein) was higher than that in the LM (30.4 fmol mg(-1) protein). 7. The molecular study (reverse transcription polymerase chain reaction) demonstrated the expression of 5-HT(7) receptor mRNA in the CM was higher than that in the LM. 8. These results suggest that the muscle layer-dependent difference in inhibition by 5-HT is not restricted to spontaneous contraction but applies to various contractions in the porcine myometrium. Different inhibition of the contractility by 5-HT is caused by muscle layer-related accumulation of cyclic AMP (CM>LM), due to smooth muscle-layer dependent distribution (CM>LM) of 5-HT(7) receptors.  (+info)

Serotonin and pancreatic duct function. (6/38)

1. 5-HT inhibits spontaneous fluid secretion as well as stimulated secretion with secretin (cAMP mediated) or ACh (Ca2+ mediated) in the isolated guinea pig pancreatic ducts. 2. The inhibitory effect of 5-HT is reversible and is dependent on the concentration in the range 0.01-0.1 microM, which is much lower than those that affect intestinal motility and secretion. 3. The 5-HT3 receptor in duct cells appears to mediate the inhibitory effect of 5-HT. 4. [Ca2+]i is unlikely to mediate the inhibitory effect of 5-HT.  (+info)

Modulation by serotonin 5-HT(4) receptors of long-term potentiation and depotentiation in the dentate gyrus of freely moving rats. (7/38)

Tetanization-induced long-term potentiation (LTP) in the hippocampus can be depotentiated by low-frequency stimulation. 5-HT(4) receptors are expressed in the hippocampus and are suggested to be involved in hippocampus-dependent cognitive processes. Since the role of these receptors in the dentate gyrus has yet not been characterized, this study investigated the effects of 5-HT(4) receptors on basal synaptic transmission, LTP and depotentiation in the dentate gyrus of freely moving rats. Male Wistar rats were chronically implanted with a recording electrode in the dentate gyrus granule cell layer, a stimulation electrode in the medial perforant path and a cannula for drug administration in the ipsilateral ventricle. The 5-HT(4) agonist methoxytryptamine dose-dependently inhibited basal synaptic transmission and LTP. Priming of receptors by a dose of this agonist which elicited no significant change of basal synaptic transmission inhibited depotentiation. These effects could be prevented by the 5-HT(4) antagonist RS 39604, which did not produce independent effects on synaptic transmission, LTP or depotentiation. The effects of methoxytryptamine were confirmed with the highly selective 5-HT(4) agonist, RS 67333. These results strongly support a role for 5-HT(4) receptors in hippocampal synaptic plasticity and provide an important link to findings with regard to the involvement of 5-HT in processes related to learning and memory.  (+info)

Activity-dependent bidirectional regulation of GABA(A) receptor channels by the 5-HT(4) receptor-mediated signalling in rat prefrontal cortical pyramidal neurons. (8/38)

Emerging evidence has implicated a potential role for 5-HT(4) receptors in cognition and anxiolysis. One of the main target structures of 5-HT(4) receptors on 'cognitive and emotional' pathways is the prefrontal cortex (PFC). As GABAergic signalling plays a key role in regulating PFC functions, we examined the effect of 5-HT(4) receptors on GABA(A) receptor channels in PFC pyramidal neurons. Application of 5-HT(4) receptor agonists produced either an enhancement or a reduction of GABA-evoked currents in PFC neurons, which are both mediated by anchored protein kinase A (PKA). Although PKA phosphorylation of GABA(A) receptor beta3 or beta1 subunits leads to current enhancement or reduction respectively in heterologous expression systems, we found that beta3 and beta1 subunits are co-expressed in PFC pyramidal neurons. Interestingly, altering PKA activation levels can change the direction of the dual effect, switching enhancement to reduction and vice versa. In addition, increased neuronal activity in PFC slices elevated the PKA activation level, changing the enhancing effect of 5-HT(4) receptors on the amplitude of GABAergic inhibitory postsynaptic currents (IPSCs) to a reduction. These results suggest that 5-HT(4) receptors can modulate GABAergic signalling bidirectionally, depending on the basal PKA activation levels that are determined by neuronal activity. This modulation provides a unique and flexible mechanism for 5-HT(4) receptors to dynamically regulate synaptic transmission and neuronal excitability in the PFC network.  (+info)

Typically, G protein-coupled receptors interact with agonists via high- and low-affinity sites, and their relative affinities can be examined with competition experiments using a radioactive antagonist. Displacement of [3H]mesulergine by 5-HT at 5-HT2C receptors, however, fitted well to a single site-binding model with a Ki of 159 ± 12 nM (Fig. 2). This monophasic profile indicates more than 90% of receptors existing in low-affinity states for 5-HT, leaving only a negligible receptor population in high-affinity states, probably caused by high-receptor density of the cloned cells (Alberts et al., 1999). PNU-69176E concentration-dependently shifted the displacement curve to the left (Fig. 3C). The Ki for 5-HT decreased from 159 ± 12 to 86 ± 10, 36 ± 3, 10 ± 1, and 6.4 ± 0.9 nM in the presence of PNU-69176E at 2.5, 5, 10, and 20 μM, respectively.

TY - JOUR. T1 - Retroviral‐mediated transduction of p53 gene increases TGF‐β expression in a human glioblastoma cell line. AU - Fujiwara, Toshiyoshi. AU - Mukhopadhyay, Tapas. AU - Cai, De Wei. AU - Morris, Danna K.. AU - Roth, Jack A.. AU - Grimm, Elizabeth A.. PY - 1994/3/15. Y1 - 1994/3/15. N2 - Transforming growth factor‐β (TGF‐β) has been implicated as a potent growth regulator; the degree of responses to it, whether positive or negative, generally correlates with the stage of cell differentiation in various cell types. We examined the effect of the p53 gene, which participates in the control of cell‐cycle progression, on the expression of human TGF‐β. The human glioblastoma cell line SNB‐19, which expresses the latent form of TGF‐β, was transfected with a retroviral vector containing wild‐type p53 (wt‐p53) or p53 with a mutation (mut‐p53) at codon 273. Stable G418‐resistant SNB‐19 clones were isolated. The growth kinetics of wt‐p53 transfectants were ...

TY - JOUR. T1 - Phenoxazine derivatives induce caspase-independent cell death in human glioblastoma cell lines, A-172 and U-251 MG. AU - Shirato, Ken. AU - Imaizumi, Kazuhiko. AU - Abe, Akihisa. AU - Tomoda, Akio. PY - 2007/1. Y1 - 2007/1. N2 - The apoptotic effects of 2-amino-4,4α-dihydro-4α, 7-dimethyl-3H-phenoxazine-3-one (Phx-1) and 2-amino-phenoxazine-3-one (Phx-3) on human glioblastoma cell lines, A-172 and U-251 MG were studied. These phenoxazines extensively decreased the viability of A-172 and U-251 MG cells (IC50 of Phx-1: 60 μM, in both lines; IC50 of Phx-3: 10 and 3 μM, for A-172 and U-251 cells, respectively). Phx-1 and Phx-3 increased the population of annexin V and PI double-positive cells in A-172 and U-251 MG cells, resulting in cell death at late stage apoptosis/necrosis. The activities of caspase-3/7 were greatly increased in A-172 and U-251 MG cells treated with Phx-1 or Phx-3. However, a pan-caspase inhibitor, z-VAD-fmk, failed to reverse the antiproliferative and ...
The ability of 5-hydroxyl-L-tryptophan (5-HTP) or pentobarbital anesthesia to elevate rat serum GH levels is completely blocked by the simultaneous administration of the serotonin antagonist cyprophepatidine, as well as by the pineal gland principles melatonin and 5-methoxytryptamine (5-MT), and by the 0-methylated dopamine derivative 3,4-dimethoxyphenylethylamine (DMPEA). Small doses of 5-MT cause paradoxical elevations in serum rat GH but at the same time inhibit the action of 5-HTP. Blockade of dopaminergic pathways by treatment with either DMPEA or chlorpromazine causes a slight, nonsignificant suppression of serum GH in normal rats while serum prolactin levels are increased greater than tenfold showing that, unlike prolactin, rat GH is not subject to tonic inhibitory control by dopamine. The data presented support the recently advanced hypothesis that rat GH is under serotoninergic CONTROL AND DEMONSTRATE THAT GH secretion can be significantly suppressed by serotoninergic blockade. It is suggested
5,N-dimethyl-N-isopropyltryptamine (5-Me-MiPT) is a tryptamine derivative that is thought to be a psychedelic drug. It was first made in 1989.

Therapeutic interest in augmentation of 5-hydroxytryptamine2A (5-HT2A) receptor signaling has been renewed by the effectiveness of psychedelic drugs in the treatment of various psychiatric conditions. In this study, we have further characterized the pharmacological properties of the recently developed 5-HT2 receptor agonist N-2-hydroxybenzyl)-2,5-dimethoxy-4-cyanophenylethylamine (25CN-NBOH) and three structural analogs at recombinant 5-HT2A, 5-HT2B, and 5-HT2C receptors and investigated the pharmacokinetic properties of the compound. 25CN-NBOH displayed robust 5-HT2A selectivity in [3H]ketanserin/[3H]mesulergine, [3H]lysergic acid diethylamide and [3H]Cimbi-36 binding assays (Ki2C/Ki2A ratio range of 52-81; Ki2B/Ki2A ratio of 37). Moreover, in inositol phosphate and intracellular Ca2+ mobilization assays 25CN-NBOH exhibited 30- to 180-fold 5-HT2A/5-HT2C selectivities and 54-fold 5-HT2A/5-HT2B selectivity as measured by Δlog(Rmax/EC50) values. In an off-target screening 25CN-NBOH (10 μM) ...
NAS může hrát roli v antidepresivních účincích selektivních inhibitorů zpětného vychytávání serotoninu (SSRI) a inhibitorů monoaminooxidázy (MAOI). [3] SSRI fluoxetin a MAO-A inhibitor klorgylin zvyšuje AANAT nepřímo prostřednictvím serotonergních mechanismů, a tím zvedá hladinu NAS po chronickém podávání, a to koreluje s nástupem jeho antidepresivních účinků.

BACKGROUND: Although irritable bowel syndrome (IBS) is not a life-threatening condition, it can have a serious impact on a patients daily activities and quality of life. This effect on quality of life has not been compared previously across different cultures.. METHODS: We compared measures of health-related quality of life and health care resource utilization using a cross-sectional point-in-time postal survey of a random sample of 500 members of the International Foundation for Functional Gastrointestinal Disorders in the US and 500 members of the IBS Network support group in the UK. The analysis was limited to persons who reported that a physician had told them they had IBS. A general health status questionnaire, the SF-36, and a disease-specific questionnaire, the Irritable Bowel Syndrome Quality of Life questionnaire (IBSQOL), were self-administered as part of the survey to measure health-related quality of life. Results on the SF-36 were compared with published normative data for adults ...
As a well-known animal hormone, melatonin (N-acetyl-5-methoxytryptamine) is also involved in multiple plant biological processes, especially in various stress responses. Rice is one of the most important crops, and melatonin is taken in by many people everyday from rice. However, the transcriptional profiling of melatonin-related genes in rice is largely unknown. In this study, the expression patterns of 11 melatonin related genes in rice in different periods, tissues, in response to different treatments were synthetically analyzed using published microarray data. These results suggest that the melatonin-related genes may play important and dual roles in rice developmental stages. We highlight the commonly regulation of rice melatonin-related genes by abscisic acid (ABA), jasmonic acid (JA), various abiotic stresses and pathogen infection, indicating the possible role of these genes in multiple stress responses and underlying crosstalks of plant hormones, especially ABA and JA. Taken together, this
3. ___ dump. ___, a naturally occurring serotonin agonist causes vivid hallucinations and a dream-like state. I am personally familiar with drug experiences related to serotonin agonist/antagonists (___) from my teen years in the early 70s. I have had no personal experience with ___ but have seen patients under its influence. The rich ultra-reality would still require fairly intact auditory and visual neocortex as target regions in which to generate such a rich audiovisual experience as I had in a coma. Prolonged coma due to bacterial meningitis had badly damaged my neocortex, which is where all of the serotonin from the raphe nuclei in my brainstem (or ___, a serotonin agonist) would have had effects on visual/auditory experiences. But my cortex was off, and the ___ would have no place in the brain to act. - See more at: www.spiritscienceandmetaphysics.com... ...

Melatonin (N-acetyl-5-methoxytryptamine) is secreted during the dark hours at night by pineal gland, and it regulates a variety of important central and peripheral actions related to circadian rhythms and reproduction. It has been believed that melatonin regulates ovarian function by the regulation of gonadotropin release in the hypothalamus-pituitary gland axis via its specific receptors. In addition to the receptor mediated action, the discovery of melatonin as a direct free radical scavenger has greatly broadened the understanding of melatonins mechanisms which benefit reproductive physiology. Higher concentrations of melatonin have been found in human preovulatory follicular fluid compared to serum, and there is growing evidence of the direct effects of melatonin on ovarian function especially oocyte maturation and embryo development. Many scientists have focused on the direct role of melatonin on oocyte maturation and embryo development as an anti-oxidant to reduce oxidative stress induced by
The type beta transforming growth factors (TGF) are potent regulators of the growth and functions of lymphocytes and macrophages. Recently the human glioblastoma cell line 308 was shown to produce TGF-beta 2. The relevance of this finding was evaluated further by comparing human glioblastoma cells with their nontransformed animal counterpart, astrocytes, with regard to the production of the three TGF-beta isoforms observed so far in mammals. In this report astrocytes are demonstrated to secrete also TGF-beta 2 and to express TGF-beta 1, -beta 2, and -beta 3 mRNA in vitro. In contrast, cultured murine brain macrophages release TGF-beta 1 and are positive for TGF-beta 1 mRNA only. Glia cell-derived TGF-beta 1 and -beta 2 are detected in latent form whereas both latent and active TGF-beta are identified in the supernatant of three human glioblastoma cell lines tested. These cell lines, however, show heterogeneity in regard to the isoform of TGF-beta expressed but share with astrocytes the inability ...

WHI-P154 is first described as a JAK3 inhibitor that displays no activity at JAK1 or JAK2. WHI-P154 inhibits STAT1 activation, iNOS expression and NO production in macrophages in vitro. But it is proved that WHI-P154 also inhibits other common kinases including EGFR, Src, Abl, VEGFR, MAPK and PI3-K and induces apoptosis in human glioblastoma cell lines. [1] WHI-P154 inhibits glioblastoma cell adhesion and migration in the context of ECM.[2] WHI-P154 exhibits significant cytotoxicity against U373 and U87 human glioblastoma cell lines, causing apoptotic cell death at micromolar concentrations. The in vitro antiglioblastoma activity of WHI-P154 is amplified > 200-fold and rendered selective by conjugation to recombinant human epidermal growth factor (EGF). In vitro treatment with EGF-P154 results killing of glioblastoma cells at nanomolar concentrations with an IC50 of 813 nM, whereas no cytotoxicity against EGF-R-negative leukemia cellsis observed, even at concentrations as high as 100 ...
So -- getting down to basics. If you want to take melatonin for anti-aging purposes, how much should you take? [Jteiber, this is response to your query as well.] No one knows with any certainty. The theory that many people are proposing is that you should aim to recreate the melatonin levels you had in your youth, which, for many people, is between 75-150 picograms per ml. This amounts to hormone replacement therapy. How much melatonin do you need to take to attain those levels? It depends on the preparation you are using (sublingual, timed-release or fast release) and the vagaries of your own liver. If you have an efficient liver, it will filter out as much as 90 percent of the melatonin, converting it to 6-hydroxymelatonin. Eventually, it is secreted in the urine. If your liver is sluggish, more of the melatonin will enter your bloodstream. This tends to happen as you age. [Pineal Melatonin: Cell Biology of its synthesis and of its physiological interactions.

In vertebrates, the essential amino acid L-tryptophan is the precursor of 5-methoxyindoles, or indolamines/tryptamines, including melatonin (N-acetyl-5-methoxytryptamine), through the intermediate serotonin (5-HT, 5-hydroxytryptamine) and the activity of hydroxyindole-O-methyltransferase (HIOMT) [14]. In mammals, melatonin is synthesized in the pineal gland, predominantly during the night-time, although it can be also produced in other organs, such as retina, gastrointestinal tract, lymphocytes and bone marrow cells. Conversely, light at night has an inhibitory effect on pineal melatonin biosynthesis which is initiated by the uptake of tryptophan from the circulation into pinealocytes [15]. Once synthesized, melatonin is not stored in the pineal cells, but it is released into the bloodstream with a circadian rhythm, from which it reaches other body fluids, including urine, saliva, cerebrospinal fluid, bile, semen and amniotic fluid [16, 17]. The circadian rhythm of melatonin secretion is ...

Cell culture. The human glioblastoma cell line U87-MG [American Type Culture Collection (ATCC), Manassas, VA] was used in all animal experiments. U87-MG were cultured in MEM-α (Life Technologies, Inc., Grand Island, NY) supplemented with 2 mmol/L l-glutamine, 2 mmol/L sodium pyruvate, 100 units/mL penicillin, 0.25 μg/mL streptomycin fungizone, and 10% fetal bovine serum (FBS; Life Technologies). Cells were maintained in T-25 tissue culture flasks in 5% CO2/95% air at 37°C in a humidified incubator and were routinely passaged at confluency. For the intracranial transplantation experiments, U87 cells were dispersed with a 0.05% solution of trypsin/EDTA (Life Technologies), washed with PBS, and adjusted to a final concentration of 5 × 104cells/10 μL in PBS. The porcine aortic endothelial cell line stably transfected with KDR (PAE/KDR; ATCC) was used as control for the migration experiments. These cells were cultured in Hams F-12 medium with 10% FCS and 10 μg/mL geneticin (G-418 sulfate). ...
