Pixelwise correlation of each 18F tracer and 131I-SIP(L19) uptake revealed higher correlation coefficients for 18F-fluorocholine and 18F-FET than for 18F-FDG. These findings may be explained by the different metabolic pathways.. 18F-Fluorocholine is a choline analog and has uptake characteristics similar to those of radiolabeled natural choline (11,26). Choline, an essential compound of the cell membrane, is transported into mammalian cells and then phosphorylated by choline kinase (27). In a further step, it is metabolized to phosphatidylcholine, which is incorporated into the cell membrane. In previous studies, the increased choline uptake in tumor cells was explained mainly by the upregulation of choline kinase due to an increased demand of membrane constituents (28,29). Consequently, further in vitro and in vivo studies postulated the use of choline analogs as a marker for tumor proliferation (9,29,30). Because 18F-fluorocholine mimics natural choline, it might be a potential tracer of ...
Choline is a crucial nutrient that contributes to several biological functions and serves as a precursor molecule to the neurotransmitter acetylcholine. Choline is integral to the development and function of the central nervous system, and its availability during the prenatal period has lasting and protective effects on neural function. Researchers have found that prenatal choline supplementation in the rat enhances learning and memory processes later in life, especially those involving spatial memory. Researchers have also demonstrated that choline protects against a number of physical stressors to the neural environment, such as prenatal alcohol exposure, induced seizures, and chronic stress-induced exposure to corticosteroids. Compared to the study of these types of physical stressors, relatively little research has examined the influence of prenatal choline exposure on psychological stress later in life. In an attempt to contribute to this field, the present study examined the effects of prenatal
Water maze experience and prenatal choline supplementation differentially promote long-term hippocampal recovery from seizures in adulthood.

Purpose: 11C-Choline positron emission tomography (PET) has been exploited to detect the aberrant choline metabolism in tumors. Radiolabeled choline uptake within the imaging time is primarily a function of transport, phosphorylation and oxidation. Rapid choline oxidation, however, complicates interpretation of PET data. In this study we investigated the biological basis of the oxidation of deuterated choline analogues and assessed their specificity in human tumor xenografts. Experimental Design: 11C-Choline, 11C-methyl-[1,2-2H4]-choline (11C-D4-choline) and 18F-D4-choline were synthesized to permit comparison. Biodistribution, metabolism, small-animal PET studies, and kinetic analysis of tracer uptake were performed in human colon HCT116 xenograft-bearing mice. Results: Oxidation of choline analogs to betaine was highest with 11C-choline, with reduced oxidation observed with 11C-D4-choline and substantially reduced with 18F-D4-choline; suggesting that both fluorination and deuteration were ...
BACKGROUND. The choline oxidation pathway comprises the sequential metabolism of choline into betaine, dimethylglycine (DMG), and sarcosine. In addition, dietary choline and betaine can be turned into trimethylamine N-amino oxide (TMAO). Alterations in choline metabolism may relate to cardiovascular disease (CVD) and type 2 diabetes (T2D). Several investigations have focused on systemic concentrations of choline and betaine; however large-scale prospective data are scarce. There is therefore a need for more comprehensive assessments of choline metabolites in relation to incident CVD, T2D and mortality, in addition to investigating any potential benefit in risk prediction from such biomarkers. AIM. We carried out observational cohort studies of the prospective relationships between plasma DMG and incident acute myocardial infarction (AMI) and mortality, as well as the association between systemic and urinary choline metabolites with the risk of incident T2D. The biomarkers impact on model ...

The placental epigenome regulates processes that affect placental and fetal development, and could be mediating some of the reported effects of maternal choline supplementation (MCS) on placental vascular development and nutrient delivery. As an extension of work previously conducted in pregnant mice, the current study sought to explore the effects of MCS on various epigenetic markers in the placenta. RNA and DNA were extracted from placentas collected on embryonic day 15.5 from pregnant mice fed a 1X or 4X choline diet, and were subjected to genome-wide sequencing procedures or mass-spectrometry-based assays to examine placental imprinted gene expression, DNA methylation patterns, and microRNA (miRNA) abundance. MCS yielded a higher (fold change = 1.63-2.25) expression of four imprinted genes (Ampd3, Tfpi2, Gatm and Aqp1) in the female placentas and a lower (fold change = 0.46-0.62) expression of three imprinted genes (Dcn, Qpct and Tnfrsf23) in the male placentas (false discovery rate (FDR) ≤ 0.05

The influence of choline availability on acetylcholine (ACh) release in the hippocampus of the awake rat was investigated using the microdialysis procedure. Three treatments enhancing choline availability for basal and atropine-evoked ACh release were evaluated: acute administration of choline chloride (20 mg/kg i.p.); pretreatment of animals with nicotinamide (10 mmol/kg s.c.) 2 hr before atropine injection and dietary choline supplementation (5-fold increase of choline intake for 15-18 days). Although acute choline administration led to a short-lasting (15 min) increase of basal choline efflux by 25% and nicotinamide caused a long-lasting (5 hr) increase by 105%, neither one affected basal ACh release. However, basal release of choline (1.38 pmol/min) and of ACh (114 fmol/min) in the hippocampus was slightly increased in choline-supplemented animals (choline: 1.92 pmol/min; ACh: 140 fmol/min). In untreated animals, atropine administration caused a 3-fold increase of ACh efflux that lasted ...
Not all sources of choline are the same. Choline itself is the basic form (also referred to as basic choline) and is usually purchased as bitartrate. Basic choline is just that-the most basic and inexpensive form of choline. It is far less expensive than CDP-choline and as a result, it is used much more often in various supplements. Basic choline does not effectively cross the blood-brain barrier and doesnt reliably increase neural (brain) concentrations of choline. While the basic form of choline does have some benefits to your liver and may help with methylation, its benefits are definitely lacking when it comes to helping your brain.. Another basic form of choline is choline citrate. This form can have about 50% more choline content than choline bitartrate and may have some other health benefits, such as helping to prevent fatty deposits from accumulating in the liver. Unfortunately, it is also ineffective at crossing the blood-brain barrier or increasing choline concentrations in ...
Magnetic resonance (MR) has become one of the most important diagnostic tools in modern medicine. It provides superior soft tissue contrast compared to other imaging modalities, it is extremely flexible as it can be used to image all parts of the body, and it is considered to be safe for patients.. Today almost all MR is performed in a non-quantitative manner, only by comparing neighbouring tissue in the search for pathology. It is possible to quantify the MR-signals to its physical entities, but time consuming and complicated calibration procedures have prevented this in clinical routine.. In this work two different applications of quantitative MR-spectroscopy in diffuse liver and neurological disease, and a new rapid method for simultaneous quantification of proton density, T1 relaxation and T2* relaxation in MR-imaging are presented.. In Paper I, absolutely quantified phosphorus MR-spectroscopy was tested as a predictive tool in order to determine the degree of fibrosis on patients with ...

Regular physical exercise not only enhances fitness but also has a positive impact on brain metabolism, researchers say. The findings showed that physical activity prevented an increase in choline - a macronutrient thats important for liver function, normal brain development, nerve function, muscle movement, supporting energy levels and maintaining a healthy metabolism.. The concentration of this metabolite often rises as a result of the increased loss of nerve cells, which typically occurs in the case of Alzheimers disease, said Johannes Pantel, Professor at the Goethe University Frankfurt in Germany. In the study, physical exercise led to stable cerebral choline concentrations in the training group, whereas choline levels increased in the control group. The participants physical fitness also improved and they showed increased cardiac efficiency after the training period.. Overall, these findings suggest that physical exercise not only improves physical fitness but also protects cells. To ...
High choline purity, guaranteed by IC (Ion Chromatography)Choline chloride is an essential nutrient and an important component in the regulation of certain metabolic processes. As choline chloride is synthesized in the liver, it is naturally available. It is however required in greater amounts than the body produces. Therefore choline chloride is an essential B-Vitamin and a required dietary supplement. Impextraco offers different choline chlorides within the KOLVIT® range.
Anaerobic choline metabolism by human gut microbiota to produce trimethylamine (TMA) has recently evolved as a potential therapeutic target because of its association with chronic kidney disease and increased cardiovascular risks. Limited examples of choline analogs have been reported as inhibitors of bacterial enzyme choline TMA-lyase (CutC), a key enzyme regulating choline anaerobic metabolism. We utilized a new workflow to discover CutC inhibitors based on focused screening of a diversified library of small molecules for intestinal metabolic stability followed by in vitro CutC inhibitory assay. This workflow identified a histidine-based scaffold, (compound 5), as a CutC inhibitor with an IC50 value of 1.9 ± 0.2 μM. Remarkably, compound 5 was able to reduce the production of TMA in whole cell assays using various bacterial strains as well as in complex gut microbiota environment. The improved efficiency of the new scaffold identified in this study in comparison to previously reported CutC ...

BACKGROUND AND PURPOSE: Choline positron emission tomography (PET) can help to optimize radiation treatment strategy of prostate cancer. Therefore, the aim of this study was to elucidate the effects of ionizing radiation on the choline uptake in an androgen-dependent (LNCaP) and an androgen-independent (PC3) prostate cancer cell line. MATERIAL AND METHODS: Uptake of [methyl-(3)H]choline chloride was investigated between 4 and 96 h after irradiation with 6 Gy. Dose dependence of choline uptake was examined following irradiation with 2-12 Gy, and cell survival was analyzed via the clonogenic assay. Michaelis-Menten kinetics was determined 24 h (PC3) and 48 h (LNCaP) after irradiation with 6 Gy. RESULTS: PC3 cells showed a significant transitory increase of [methyl-(3)H]choline uptake with a maximum at 24 h after irradiation. In LNCaP cells irradiation induced a significant decrease with a minimum at 48 h. Changes in choline uptake in both cell lines were almost dose-independent up to 12 Gy. ...
The aim of this study was to prospectively compare the detection rate of 68Ga-PSMA versus 11C-Choline in men with prostate cancer with biochemical recurrence and to demonstrate the added value of a tri-modality PET/CT-MRI system. We analysed 36 patients who underwent both 11C-Choline PET/CT and 68Ga-PSMA PET/CT scanning within a time window of 1-2 weeks. Additionally, for the 68Ga-PSMA scan, we used a PET/CT-MRI (3.0 T) system with a dedicated shuttle, acquiring MRI images of the pelvis. Both scans were positive in 18 patients (50%) and negative in 8 patients (22%). Nine patients were positive with 68Ga-PSMA alone (25%) and one with 11C-Choline only (3%). The median detected lesion per patient was 2 for 68Ga-PSMA (range 0-93) and 1 for 11C-Choline (range 0-57). Tumour to background ratios in all concordant lesions (n = 96) were higher for 68Ga-PSMA than for 11C-Choline (110.3 ± 107.8 and 27.5 ± 17.1, mean ± S.D., for each tracer, respectively P = 0.0001).

The aim of the present study was to investigate the function of human CTL1 in choline transport. The function of CTL1 as a choline transporter has been demonstrated in the Torpedo electric lobe (40), mouse (57), and rat (16, 40, 47). Human CTL1 was cloned and characterized as a cell-surface antigen in monocytes and differentiating dendritic cells; however, its choline transport was not clearly established (55). This study is the first to establish a functional link between the regulation of surface expression of CTL1 protein and choline transport in monocytes and differentiated macrophages. We realized that the well-known induction process of monocytic cell differentiation to macrophages by PMA is a good model for our study because the PMA/PKC system has the following properties: 1) they contribute to the differentiation processes, 2) they are common modulators of choline uptake in multiple systems, and 3) they are well-documented regulators of surface receptors and transporters (3, 10, 24, ...

PURPOSE: We have previously reported results of a pilot study in patients with locally advanced breast cancer receiving primary systemic chemotherapy (PST) showing that a decrease in tumor choline concentration ([tCho]) measured one day after starting treatment was associated with clinical response based on MRI. In this follow-up study with a larger cohort, we assessed whether early changes in [tCho] were associated with clinical response, based on both MRI and pathology, and survival.. METHODS AND MATERIALS: Women with locally advanced breast cancer scheduled for PST were scanned using a high-field MRI/MRS protocol prior to treatment, day 1 after treatment, and at the end of the first course of chemotherapy. MRI/MRS was performed on a 4 T Varian system with unilateral transmit/receive breast coils. MRI consisted of contrast-enhanced T1-weighted 3D gradient echo scans with one-minute temporal resolution. A single-voxel MR spectrum was acquired from the index lesion after MRI, and the ...

The effects of several non-neuronal cell types on neurotransmitter synthesis in cultures of dissociated sympathetic neurons from the new-born rat were studied. Acetylcholine synthesis from radioactive choline was increased 100- to 1000-fold in the presence of non-neuronal cells from sympathetic ganglia. This increase was roughly dependent on the number of ganglionic non-neuronal cells present. The effect did not appear to be due to an increased plating efficiency of neurons, since the non-neuronal cells were capable of increasing acetylcholine synthesis after only 48-hr contact with neurons that had been previously grown without non-neuronal cells for 2 weeks. C6 rat glioma cells were also able to stimulate acetylcholine synthesis, but 3T3 mouse fibroblast cells had little or no effect. None of the non-neuronal cell types synthesized detectable acetylcholine in the absence of the neurons. The ganglionic non-neuronal cells had no significant effect on catecholamine synthesis (which occurs in the ...

Y1 - 1986/7/23. N2 - We have previously reported that a diet supplemented with choline induces an increase in the concentration of a brain nicotinic-like receptor, as measured by α-bungarotoxin (BuTX) binding. Here we report the effects of choline administered in the drinking water on BuTX binding in the cortex, midbrain and brainstem of rats at 3 ages. In comparison with animals fed a choline-free diet, choline supplementation produced increases averaging 50% in 23-day-old rats and increases of approximately 30% in 60-day-old rats. Increases were also found in 6-month-old animals (averaging 16%), but the differences were generally not statistically significant. The mechanism responsible for the increase in the concentration of BuTX binding sites following the administration of dietary choline is not ...

Advanced imaging of veterinary cancer patients has evolved in recent years and modalities once limited to human medicine have now been described for diagnostic purposes in veterinary medicine (positron emission tomography/computed tomography, single-photon emission computed tomography, whole body magnetic resonance imaging). Magnetic resonance spectroscopy (MRS) is a non-invasive and non-ionizing technique that is well described in the human medical literature and is most frequently used to evaluate the metabolic activity of tissues with questionable malignant transformation. Differentiation of neoplastic tissue from surrounding normal tissue is dependent on variations in cellular metabolism. Choline (Cho) levels have been described as diagnostic markers for malignancy for many different tumor types in vivo and ex vivo (tissue biopsies). Monitoring of pre- and post-therapy choline metabolites in tumors has also been performed to evaluate a patients response to cancer treatment. Positive ...

Electrical stimulation of the chick ciliary nerve leads to a frequency-dependent increase in the Na+-dependent high affinity uptake of [3H]choline (SDHACU) and its conversion to acetylcholine (ACh) in the nerve terminals innervating the iris muscle. The forces that drive this choline (Ch) uptake across the presynaptic membrane were evaluated. Depolarization with increased [K+] out or veratridine decreases Ch accumulation. In addition to the electrical driving force, energy is provided by the Na+ gradient. Inhibition of the Na,K-ATPase decreased the Ch taken up. Thus, changes in the rate of Ch transport are dependent on the electrochemical gradients for both Ch and Na+. Ch uptake and ACh synthesis were increased after a conditioning preincubation with high [K+] out or veratridine. As is the case for electrical stimulation, this acceleration of Ch uptake and ACh synthesis was strongly dependent on the presence of Ca++ in the incubation medium. Na+ influx through a TTX-sensitive channel also ...

Choline- and acetylcholine-induced changes in the morphology of Fusarium graminearum: evidence for the involvement of the choline transport system and acetylcholinesterase
Choline for ACh biosynthesis can potentially be supplied through three pathways: (1) de novo synthesis, (2) uptake of free choline by low- and high-affinity transporters, and (3) turnover of membrane phospholipids. Assessing the relative contributions of these pathways from the literature is somewhat difficult. Observations on the mouse CHT knockout suggest that choline uptake through the high-affinity transporter is critical for the synthesis of synaptically releasable pools of ACh (Ferguson et al. 2004). However, as noted earlier, researchers have also reported that a small, but significant fraction (∼20%) of ACh synthesis is independent of HC-3-sensitive choline uptake (Birks and Macintosh 1957; Guyenet et al. 1973). Other researchers have demonstrated that neuroendocrine cells are capable of synthesizing and releasing ACh in the absence of detectable CHT expression (Bauerfeind et al. 1993; Ferguson et al. 2003). These observations are generally attributed to the activity of low-affinity ...

And in the unfortunate case that you do believe that you are running short of choline, because you dont eat all the good choline containing foods out of ethical or whatever other reasons, and thus insist on supplementing, I suggest you yourself a 500g container of choline bitartrate powder (dont let that become wet, though! It will stink like rotten fish ;-). Those 500g of choline bitartrate (40% choline, 60% tartate) will cost you about as much as 60x300mg caps of the overpriced GPC and has been scientifically proven (not in supplement company terms, but in SuppVersity terms) to safely increase circulating and brain choline levels and its metabolites after oral ingestion, as well (Stoll. 1996; Babb. 2004). And lets be honest, even if the effects on growth hormone were GPC specific - even on the boards, people have meanwhile realized none of those arginine + lysine GH boosters does make a difference and not because they would not produce transient increases in GH, but simply because those ...

Affiliation:Centro Ricerche Cliniche, Telemedicina e Telefarmacia Università di Camerino, Via Madonna delle Carceri 9, 62032 Camerino (MC) Italy.. Keywords:Adult-onset dementia, choline alphoscerate, cholinergic neurotransmission, clinical trials, preclinical studies.. Abstract:Cholinergic precursors have represented the first approach to counter cognitive impairment occurring in adultonset dementia disorders. These compounds were early leaved because their clinical efficacy was not clearly demonstrated. This is probably not true for some choline-containing phospholipids including choline alphoscerate. Choline alphoscerate increases the release of acetylcholine in rat hippocampus, facilitates learning and memory in experimental animals, improves ...
PtdCho is a major component of eukaryotic but not prokaryotic membranes. We demonstrate for the first time that a bacterium can inhibit the de novo synthesis of PtdCho in human cells. Significantly, this inhibition triggers apoptosis. Although inhibition of PtdCho biosynthesis initiates apoptosis in cells exposed to xenobiotics (13-15, 17, 28), in mutant cells with genetic CCT dysfunction (40), or in nutritional choline deprivation (18, 31), the response of human cells to pneumococcus is the first case where this mechanism plays a critical role in pathogenesis.. In the brain, PtdCho has an additional role as a precursor for the biosynthesis of the important neurotransmitter acetylcholine. It is unlikely that acetylcholine deprivation accounts for the observed pneumococcal-induced neuronal cell death because a low level of acetylcholine is not known to be a death signal and PtdCho serves as a reservoir of choline for acetylcholine biosynthesis under conditions of nutritional choline deprivation ...
After the impulse is transmitted across the synapse, the acetylcholine is broken down by the enzyme cholinesterase. 83+ Ways to Increase or Decrease Acetylcholine. Choline is a precursor for acetylcholine, an important neurotransmitter synthesized by cholinergic neurons and involved in muscle control, circadian rhythm, memory, and many other neuronal functions. Acetylcholine (ACh) is a neurotransmitter that has been receiving a lot of attention in memory research. It is the main neurotransmitter released into the nerves throughout your body (excluding your spinal cord and brain), and is responsible for … While your liver makes choline, it doesnt make enough to meet your daily needs so its … If youre trying to make more acetylcholine, you have to increase your choline levels. These compounds are toxic because they inhibit the action of acetylcholinesterase, leading to a build-up of acetylcholine. Acetylcholine, a biochemical, plays a large role in maintaining your hearts rhythm when you ...
Choline kinase alpha (ChoK) overexpression is connected with an aggressive tumor phenotype. in 4175-Luc+ tumors that LY500307 was followed by concomitant decrease in JAS239 uptake and reduced total choline metabolite amounts as assessed using magnetic resonance spectroscopy. At higher healing dosages, JAS239 was as effectual as MN58b at arresting tumor development and inducing apoptosis in MDA-MB-231 tumors, considerably reducing tumor choline below baseline amounts without observable systemic toxicity. These data bring in a new solution to monitor therapeutically effective inhibitors of choline fat burning capacity in breasts cancer utilizing a little molecule partner diagnostic. phospholipid biosynthesis qualified prospects to lower degrees of pro-mitotic second messenger Kennedy pathway intermediates, elevated ceramide amounts, and de-stabilized endoplasmic reticulum [2, 17C19]. The strongest of these agencies, TCD-717, is certainly a appealing anti-cancer medication [19] thats being ...

The neurotransmitter acetylcholine (ACh) is bound with 50-micromolar affinity by a completely synthetic receptor (host) comprising primarily aromatic rings. The host provided an overall hydrophobic binding site, but one that could recognize the positive charge of the quaternary ammonium group of ACh through a stabilizing interaction with the electron-rich π systems of the aromatic rings (cation-π interaction). Similar interactions may be involved in biological recognition of ACh and other choline derivatives. ...

Vitamins are organic substances that are indispensable to the normal metabolic processes of animals. Vitamins are required in very small amounts and are classified as micronutrients. They are essential to maintain health and performance, and have to be supplied as part of the overall diet. Vitamins can also be ingested as pro-vitamins, which are converted into the corresponding vitamins by the animal organism. In most cases, the animal organism itself is not able to synthesise vitamins.. A deficiency or complete lack of one or more vitamins may lead to multiple metabolic malfunctions, possibly resulting in depressed performance, growth retardation, fertility problems or diseases and possibly death. Furthermore, an increased supply of certain vitamins can have positive effects on health (Fefana, 2014). Orffa can offer a broad and complete range of vitamins to the compound feed and premix industry.. Availability can depend on region. ...
Data from a large, long-running Finnish study, involving some 2,500 men aged 42-60, has found that dietary intake of phosphatidylcholine was associated with a reduced risk of dementia (the risk was 28% lower in men with the highest intake compared to the lowest). Men with the highest intake of dietary phosphatidylcholine also excelled in tests measuring their memory and linguistic abilities.. The key sources of phosphatidylcholine in the study populations diet were eggs (39%) and meat (37%).. Choline is necessary for the formation of the neurotransmitter acetylcholine. Earlier studies have linked choline intake with cognitive processing, and adequate choline intake may play a role in the prevention of cognitive decline and Alzheimers disease.. There was no interaction with the APOE4 gene.. https://www.eurekalert.org/pub_releases/2019-08/uoef-dca080619.php. ...
