TY - JOUR. T1 - Effects of dietary glutamine supplementation on lung injury induced by lipopolysaccharide administration. AU - Hou, Yu-Chen. AU - Pai, Man Hui. AU - Chiu, Wan Chun. AU - Hu, Ya Mei. AU - Yeh, Sung Ling. PY - 2009/3. Y1 - 2009/3. N2 - Acute lung injury (ALI) is a critical syndrome associated with respiratory dysfunction, and neutrophils are considered to be central to the pathogenesis of ALI. This study investigated the effects of glutamine (Gln) on neutrophil recruitment in a model of lipopolysaccharide (LPS)-induced ALI. C57BL/6 mice were fed a standard diet either with casein as the nitrogen source or with 25% of total nitrogen replaced by Gln. After 10 days, intratracheal instillation of LPS was used to induce ALI. Mice were killed at 0, 6, 12, and 24 h after LPS administration (n = 10/group). Bronchoalveolar lavage fluid and lung tissues were collected for further analysis. The results showed that, compared with the control group, lipid peroxide levels in the lungs were ...
The second part of the thesis consists of observational studies on plasma glutamine concentrations in connection to outcome and specific diagnoses. In the post ICU period, plasma glutamine concentration was within the reference range and was not related to mortality. In liver failure, regardless of aetiology, severity and course of illness, a high plasma glutamine concentration was a common finding, although most frequent in patients with acute fulminant and acute-on-chronic liver failure. There was a positive correlation between the severity of liver failure and plasma glutamine concentration. Admission hyperglutaminemia (≥930 μmol/L) was an independent predictor for high mortality. A majority of the hyperglutaminemic patients had a liver condition, although hyperglutaminemia was also observed in patients without signs of liver affection ...
Deregulated expression of MYC enhances glutamine utilization and renders cell survival dependent on glutamine, inducing "glutamine addiction". Surprisingly, colon cancer cells that express high levels of MYC due to WNT pathway mutations are not glutamine‐addicted but undergo a reversible cell cycle arrest upon glutamine deprivation. We show here that glutamine deprivation suppresses translation of endogenous MYC via the 3′‐UTR of the MYC mRNA, enabling escape from apoptosis. This regulation is mediated by glutamine‐dependent changes in adenosine‐nucleotide levels. Glutamine deprivation causes a global reduction in promoter association of RNA polymerase II (RNAPII) and slows transcriptional elongation. While activation of MYC restores binding of MYC and RNAPII function on most promoters, restoration of elongation is imperfect and activation of MYC in the absence of glutamine causes stalling of RNAPII on multiple genes, correlating with R‐loop formation. Stalling of RNAPII and R‐loop ...

Review question: In preterm infants, does glutamine supplementation reduce the risk of death or disability?. Background: Glutamine is an important nutrient for growth and development and may be especially important in protecting preterm infants from infections and gut problems that cause death and disability. We sought evidence that giving preterm infants extra glutamine improves important outcomes.. Study characteristics: We found 12 randomised controlled trials (enrolling 2877 infants in total). The trials were generally of good methodological quality.. Key results: These trials did not provide strong or consistent evidence that glutamine supplementation affected the risk of death, serious infection or bowel disease, or longer term development.. Conclusions: Glutamine supplementation is not likely to be beneficial for preterm infants.. ...
1.During infusion of [5-15N]glutamine in patients with gastrointestinal cancer we unexpectedly observed a gradual decrease in time of the appearance rate (Ra) of glutamine in plasma. Here we investigate whether the failure to achieve a plateau isotopic enrichment in plasma is, among other factors, due to incomplete equilibration of the glutamine tracer with the large intramuscular free glutamine pool.. 2.Plasma and intramuscular glutamine enrichment were measured during 6-11 ;h infusions of L-[5-15N]glutamine and L-[1-13C]glutamine in post-absorptive patients admitted to hospital for elective abdominal surgery. L-[1-13C]Leucine and L-[ring-2H5]phenylalanine were infused to measure the proportion of glutamine appearing in plasma directly due to its release from protein.. 3.The glutamine tracer entered muscle, but the rise in intramuscular glutamine enrichment was small, presumably as a result of the enormous size of the intramuscular glutamine pool and the limited speed of entry of glutamine into ...
Glutamine, a nonessential amino acid, is preferred fuel for rapidly proliferating cells in human body. Those cells include the enterocytes in small intestine, lymphocytes, macrophages, and fibroblasts. Glutamine also transports nitrogen between tissues and serves as a precursor to glutathione which is a potent antioxidant. A healthy human body contains abundant glutamine, either from diet or from skeletal muscle tissue that synthesizes it.. During critical illness the demand for glutamine is increased. Rapid depletion of glutamine stores in critically ill patients has been described and correlated to increased mortality. Glutamine depletion may be deleterious in critical illness because of adverse effects on the essential functions mentioned above. For example glutamine depletion may cause gut mucosal barrier function to deteriorate, leading to bacterial translocation and enhanced systemic inflammatory response with increased risk for multisystem organ failure. Clinical trials performed in a ...
This study aimed to establish the plasma glutamine levels in a group of mixed ICU patients. It is important as the measurement of glutamine levels is currently not readily available, expensive and impractical in most hospital settings. This research serves as a pilot study for a larger study to be conducted in the SA setting, which will further elaborate on plasma glutamine levels throughout ICU stay, taking into account severity of illness as well as nutritional status of the patients. In order to obtain a representative sample of a real-life ICU population, all patients admitted to the chosen ICUs during the study period were eligible for inclusion.. The median plasma glutamine level of this ICU population (497 μmol/L [387-644 μmol/L]) was in the normal range, with 38.2 % categorised as glutamine deficient. This is comparable with findings by Oudemans-van Straaten et al. [15], indicating a median ICU admission level of 495 μmol/L (interquartile range 350-600 μmol/L) together with other ...

ObjectiveEnteral glutamine supplements have been shown to reduce infectious morbidity in trauma patients, but their effect on burn patients is not known. The objective of this study was to measure the impact of enteral glutamine supplementation on infectious morbidity, length of care, and the immune
The patients who fulfilled the described criteria were randomly assigned to groups P or E using sequentially numbered containers for concealed randomization. Those in group P received the continuous infusion of parenteral glutamine dipeptide supplement (Dipeptiven 100ml, Fresenius Kabi) and were fed enterally with a standard commercial enteral polymeric diet without added glutamine (Ensure, Abbott Ross). The patients in group E received the enteral glutamine supplement as continuous administration of a standard commercial enteral diet supplemented with glutamine (Alitraq, Abbott Ross). The dose of the enteral glutamine, in a form of a free acid in this diet, depended on the volume of enteral food. Both groups of patients were treated with the glutamine supplement for five days. The other therapeutic procedures did not differ between the groups. All the patients were on continuous gastric feeding for 20 hours daily, starting with 20ml/hour. The enteral nutrition was started in 24 hours following ...

In the present study, we evaluated the effect of Gln supplementation on ethanol-induced gut barrier dysfunction and liver injury in mice in vivo. Ethanol feeding caused a significant increase in inulin permeability in distal colon. Elevated permeability was associated with a redistribution of tight junction and adherens junction proteins and depletion of detergent-insoluble ...
To assist in preventing OTS, consume glutamine both before and after training, and before you go to sleep. Follow the recommended dose (which usually falls between five and ten grams postworkout). Depending on your diet, you may want to consider increasing or decreasing the amount. For a high carbohydrate diet, for example, more glutamine may be appropriate. Glutamine can increase glycogen storage by as much as 16 percent if consumed post-workout.. If you consume glutamine half an hour before working out, you may see noticeable improvements in mass gains.. Side Effects. Although glutamine is not noted for having side effects, people sometimes mention those such as nausea when consuming glutamine in high quantities (above the recommended dose. In short, if you consume glutamine as recommended, you should see no problems.. As with most supplements, the amount of glutamine to take offers no one answer for everyone. Use the above recommendations as a guide and look to your body for feedback. With ...
Glutamine is one of the conditionally essential free amino acids with multiple biological functions. Its supplementation to parenteral nutrition has been widely used for the management of complications in intensive care. However, controversial clinical reports have generated reluctance in the use of this pharmaco-nutrient. In this commentary, we address the impact of four studies that influenced the recommendations on glutamine supplementation by the Canadian Clinical Practice Guide 2015. Because of the importance of this guideline in clinical practice, we strongly believe that a more rigorous and critical evaluation is required to support recommendations in future guidelines.
Advanced Recovery & Immune System Support. Glutamine is the most abundant single amino acid in the body and its considered to be conditionally essential during times when the body undergoes large amounts of stress (ex: heavy exercise). At this point your body may need more Glutamine than it can produce making supplementation advantageous. Glutamine supplementation may support the removal of waste products in the body, digestion and immune system function. Stress on the body can also result in inadequate amounts of Alanine, which along with Glutamine, is considered to be the most one of the important of the amino acids for actual amino acid metabolism. Alanine has also been shown to support the immune system as well as energy management. Glutamine Plus also features Sustamine, a unique dipeptide ingredient that combines the amino acids L-Alanine and L-Glutamine to help your body rehydrate, replenish and recover. Sustamines dipeptide structure is quickly and easily absorbed by the body ...

Glutamine is a conditionally essential amino acid that is an important metabolic resource for proliferating tissues by acting as a proteinogenic amino acid, a nitrogen donor for biosynthetic reactions and as a substrate for the citric acid or tricarboxylic acid cycle. The human immunodeficiency virus type 1 (HIV-1) productively infects activated CD4(+) T cells that are known to require glutamine for proliferation and for carrying out effector functions. As a virus, HIV-1 is furthermore entirely dependent on host metabolism to support its replication. In this study, we compared HIV-1 infected with uninfected activated primary human CD4(+) T cells with regard to glutamine metabolism. We report that glutamine concentrations are elevated in HIV-1-infected cells and that glutamine is important to support HIV-1 replication, although the latter is closely linked to the glutamine dependency of cell survival. Metabolic tracer experiments showed that entry of glutamine-derived carbon into the citric acid ...
Taking a combination product containing glutamine and other ingredients doesnt seem to improve the healing rate of foot sores in glutamine with diabetes. One early study shows that allergy glutamine by mouth reduces the duration of diarrhea glutamine children. But taking glutamine by mouth along with conventional rehydration solutions doesnt seem to have an advantage over rehydration solutions alone. Early research shows that taking glutamine might help with weight loss in obese women.. Withdrawal from heroin, morphine, and other opioid drugs. Taking a combination of glutamine and other ingredients might reduce the mood-related ffacts associated with opioid withdrawal. Swelling inflammation and facts inside the mouth oral mucositis.

The effects of dexamethasone on nitrogen and amino acid metabolism in the dog were studied in order to gain insight into the role of glucocorticoids in accelerated proteolysis and altered metabolism of glutamine in catabolic illnesses. After dexamethasone administration at a dose of 0.44 mg X day-1 X kg-1, nitrogen balance shifted from slightly positive (+0.126 g N X day-1 X kg-1) to markedly negative (-0.278 g N X day-1 X kg-1). This was associated with a 23% fall in total free amino acid nitrogen in skeletal muscle, with 80% of the decline accounted for by a decrease in glutamine. Plasma glutamine concentration decreased by 26%, although total plasma free amino acid nitrogen was unchanged because of a 49% increase in alanine. The alterations in intracellular and circulating levels of glutamine were not accompanied by measurable changes in glutamine synthetase or glutaminase activities in skeletal muscle. Hindquarter amino acid flux measurements demonstrated that the decline in intracellular ...
Studies of enterally administered glutamine supplementation to patients fed by enteral nutrition comprise a much more heterogenic patient group [29, 30, 46-50]. There are studies of exclusively trauma patients or burn patients, or there are studies that include a broad spectrum of critically ill patients with a wide range of diagnoses and consequently a very variable ICU length of stay. Not surprisingly the meta-analysis shows no mortality advantage but in many individual studies a morbidity advantage [16]. These studies represent an interpretation problem in several respects; in many cases a hypocaloric feeding, uncertainty concerning the utilization of the given supplementation, sometimes a considerable dilution effect from many included short-stayers with a low mortality rate, and a short treatment period [48].. An interesting study with a different concept uses an enteral product with key nutrients, including 30 g of glutamine per day. Some studies employing this product are small in size ...
Allmax Glutamine is a naturally occurring amino acid and one of the most abundant amino acids in the body (comprising approximately 30% of amino acids in the plasma). It is usually classified as a conditionally essential amino acid, as it is produced by the body, but during periods of extreme stress or trauma, it is released from the body and may need to be replenished. Glutamine is naturally found in beans, poultry, fish and dairy products. The majority of Glutamine is produced in the skeletal muscle and adipose tissue. Additionally, glutamine is synthesized in the lungs, liver and brain. It is predominately used for fuel by the small intestines, immune system, hair follicles and the gastrointestinal tract.. Allmax Glutamine supplementation is beneficial during periods of stress, such as after training Glutamine ensures the body remains in a state of anabolism. For those who train, supplementing with glutamine ensures the bodys stores of this important amino acid are optimized and the skeletal ...
Glutamine is taken up into the rat hepatoma cell line H4-IIE-C3 by a Na+-dependent transport system which is specific for glutamine, alanine, serine, cysteine and asparagine and does not tolerate substitution of Na+ by Li+. Glutamine transport was relatively weakly inhibited by a 50-fold excess of leucine and was not inhibited by phenylalanine or N-methyl aminoisobutyrate. These general properties are characteristic of the recently identified ASCT/B0 family of transporters. Using a reverse transcriptase PCR-based homology cloning approach, we have characterized a cDNA for a novel member of this transporter family (H4-ASCT2) from H4-IIE-C3 cells. The cDNA encodes a 551-amino acid protein which exhibits similarities of between 75 and 85% with ASCT/B0 transporters previously cloned from other sources. When expressed in Xenopus oocytes, this transporter catalyses Na+-dependent glutamine uptake with characteristics very similar to those of glutamine uptake into the H4-IIE-C3 cells. This newly ...

Metabolic acidosis redirects interorgan glutamine flow from hepatic utilization to renal ammoniagenesis at the expense of ureagenesis. The roles of arterial glutamine load and organ glutaminase capacity in the regulation of glutamine balance across the gut, liver, and kidneys were studied in control and chronically acidotic rats. In control rats these organs combined to remove 733 nmol glutamine X min-1 X 100 g-1 in agreement with their respective glutaminase content, gut greater than liver greater than kidneys. In chronic metabolic acidosis renal glutamine extraction alone increased to 1,158 nmol X min-1 X 100 g-1 associated with an increased glutaminase capacity. However, the total glutamine deficit across these organs rose to only 1,043 nmol glutamine consumed X min-1 X 100 g-1 as a consequence of hepatic glutamine uptake reversing to net release. This reversal was not dependent on increased hepatic glutamine synthetase capacity, but rather appears to be dependent on the combined effect of ...
Alcohol inhibits the production of glutamine once it enters the bloodstream. This in itself is not a bad thing; it is when the body tries to play catch-up that creates fatigue. Glutamine production revs up after the partying is done and the partier is in bed. The bonus glutamine stimulates the brain and keeps it from achieving a deep sleep. The effect of being hopped up on glutamine upon waking is fatigue, often punctuated with tremors, anxiety and feelings of restlessness. This diabolical mix of tiredness and scratchy-eyed irritability is known as "glutamine rebound" and can also lead to increased blood pressure, nausea and a host of other ailments. Ouch.. Since a glutamine rebound is the result of alcohol preventing the production of glutamine, the only real cure is not drinking alcohol, but lets be realistic; just drinking a bit less than usual will help. The liver processes alcohol at roughly one drink per hour, so if you can manage to drink fewer drinks than hours you have to sleep, you ...
In 1955 Harry Eagle found that glutamine was essential for proliferating cells. Eagle studied on nutritional needs of a cell and found that glutamine was consumed ten times more than any other amino acids. Cells were unable to multiply without glutamine. Kovacevic and collegues found, in 1971, that glutamine is used as fuel and the carbon molecules found in gluatmine was also found in the carbon dioxide excreted by the cell. Glutamine loses its amide group using the an enzyme, glutaminase, to produce glutamic acid, which then loses its amine group using glutamic acid dehydrogenase to form α-ketogluterate.. Current studies use 13C to identify the carbon movements in the conversion of glutamine to lactic acid. Gluatamine uses malic enzymes to convert to lactic acid. Malic enzymes decarboxylates malic acid making carbon dioxide, NADPH and pyruvate. The NADPH produced is then used to for the cell to multiply.. Glutamine also contributes to the cell by producing oxaloacetate according to studies ...
Proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity. In these cells, glutamine uptake is markedly enhanced and far exceeds the metabolic requirements of the cell. Much of this glutamine is inefficiently used and secreted from the cells as lactic acid, ammonia, or alanine, a situation with many parallels to the inefficient metabolism of glucose by many cancer cells (1). Glutamine is used by the cell for both bioenergetic and biosynthetic needs. Glutamine can be used an amino acid for protein synthesis, as a carbon source, or as the primary nitrogen donor for multiple essential biosynthetic reactions in the cell. Once taken up by the cell, much of the glutamine is converted to glutamate by mitochondrial glutaminase, an enzyme whose levels are
The aims of this study were twofold: (i) to determine quantitatively the contribution of glutamate/glutamine cycling to total astrocyte/neuron substrate trafficking for the replenishment of neurotransmitter glutamate; and (ii) to determine the relative contributions of anaplerotic flux and glutamate/glutamine cycling to total glutamine synthesis. In this work in vivo and in vitro (13)C NMR spectroscopy were used, with a [2-(13)C]glucose or [5-(13)C]glucose infusion, to determine the rates of glutamate/glutamine cycling, de novo glutamine synthesis via anaplerosis, and the neuronal and astrocytic tricarboxylic acid cycles in the rat cerebral cortex. The rate of glutamate/glutamine cycling measured in this study is compared with that determined from re-analysis of (13)C NMR data acquired during a [1-(13)C]glucose infusion. The excellent agreement between these rates supports the hypothesis that glutamate/glutamine cycling is a major metabolic flux ( approximately 0.20 micromol/min/g) in the cerebral
It may sound like leucine is free to exert its powerful effect of mTOR activation, but one must remember that protein breakdown and synthesis are occurring throughout the entire body; the bodys protein stores are in a constant state of flux. The constant body protein flux plus the increased BCAA/leucine oxidation caused by exercise means that leucine is in high demand and therefore may not be able to participate in muscle growth at its full potential. This is where supplementing with additional BCAAs (or free-form leucine depending on your beliefs) and glutamine comes into play. Supplementing with glutamine will help keep skeletal muscle and plasma glutamine concentrations elevated and decrease BCAA/leucine oxidation and therefore muscle catabolism. ...

Insulinemia and HOMA-IR declined by 20% after glutamine, but not significantly so ...
If total body health is your goal, then you should definitely be supplementing your diet with glutamine. Glutamine is a supplement we strongly recommend here at BodipHat. Glutamine is the most prevalent amino acid in the body. Because glutamine is so prevalent, it is also very versatile in what it does in the body. Glutamine is known mostly as an immune system booster but also has been known to aid in muscle building, fight of muscle wasting in burn victims and A.I.D.S. patients, aid in gut health and digestion, and even repair ulcers and stomach lining. On top of all these benefits glutamine has also been shown to aid with fat loss. As I mentioned earlier glutamine helps fight of muscle wasting. This is due to a "cell-volumizing" effect that glutamine has. Cell volumizing is when a cell expands in size due to its ability to absorb more water and nutrients. This reduces muscle tissue breakdown and helps keep your muscles full. This in turn helps create a better "pump". This is beneficial because ...
Exactly what are the health benefits and then challenges connected to having to take glutamine peptide to be a add to? It is essential to realize that glutamine is definitely an amino acid how the person releases effortlessly. Since it are usually created from the human body as well as end up being assimilated, it can be considered a new non-essential protein. Glutamine GHRP 6 is usually a better sort of further glutamine. Its covered by insurance with other protein and so the figure might absorb it all more quickly, considering the predictions that speedier intake provides relating to the preferred good results far sooner.. When the entire body releases glutamine typically, how come create a supplementation as efficient just as glutamine peptide? Glutamine becomes vital, indicating the system will not manufacture sufficiently, during strong physical activity, condition, and even upon a trauma. Players, specially musclemen, seek the a look at all the supplement to really make it glutamine for ...
Glutamine supplementation has been advocated for patients requiring parenteral nutritional support. However, the direct effect of glutamine on neoplastic cells is poorly understood. We therefore investigated the effects of glutamine on the proliferation, differentiation, and cell-matrix interactions of two human colon carcinoma cell lines (Caco-2 and SW620) adapted to glutamine-free media. Doubling times were calculated by logarithmic transformation of serial cell counts. Alkaline phosphatase, cathepsin C (dipeptidyl peptidase), lactase, and isomaltase expression (markers of differentiation) were assayed by digestion of synthetic substrates. Adhesion to matrix proteins was assessed by colorimetric quantitation of toluidine blue staining of adherent cells. Surface expression of Caco-2 receptors for matrix proteins (integrins) was studied by biotinylation and immunoprecipitation with specific antibodies. Glutamine (1-10 mm) dose-dependently stimulated Caco-2 proliferation on all matrices studied ...
Glutamine is a nonessential amino acid that is the most abundant free amino acid in human muscle and plasma. It is necessary for rapidly dividing cells, including those of the gut and immune system. It is also used as an energy source in mitochondria, and is a precursor of the brain neurotransmitter glutamate. Glutamine is also needed for optimal nucleotide biosynthesis and protein synthesis. Glutamine is a very diverse amino acid that is utilized in numerous functions that are important for daily living. People that do heavy exercising can lower their glutamine levels causing stress to their body and immune systems. For that reason supplementing with glutamine can be an important part of a serious athletes program or someone challenged with loss of muscle, or just wanting to help maintain optimal immune function while under heavy stress. There is evidence that undertaking prolonged, exhaustive exercise such as running a full marathon or intensive training sessions can reduce blood concentrations

Oxygenated cancer cells have a high metabolic plasticity as they can use glucose, glutamine and lactate as main substrates to support their bioenergetic and biosynthetic activities. Metabolic optimization requires integration. While glycolysis and glutaminolysis can cooperate to support cellular proliferation, oxidative lactate metabolism opposes glycolysis in oxidative cancer cells engaged in a symbiotic relation with their hypoxic/glycolytic neighbors. However, little is known concerning the relationship between oxidative lactate metabolism and glutamine metabolism. Using SiHa and HeLa human cancer cells, this study reports that intracellular lactate signaling promotes glutamine uptake and metabolism in oxidative cancer cells. It depends on the uptake of extracellular lactate by monocarboxylate transporter 1 (MCT1). Lactate first stabilizes hypoxia-inducible factor-2α (HIF-2α), and HIF-2α then transactivates c-Myc in a pathway that mimics a response to hypoxia. Consequently, lactate-induced ...
What Is It? Glutamine is classified as a “semi-essential†or “conditionally essential†amino acid. "Conditionally essential" means that under normal conditions the body can create enough glutamine to maintain a state of health and homeostasis. However, when under great stress such as when you suffer from disease, trauma, or are subjected to harsh drugs such as chemotherapy, the body exhausts its supply to glutamine. In these cases glutamine supplementation can help the body maintain the necessary quantities of glutamine to maintain healthy metabolic function. Few people who are generally healthy and follow a balanced diet are deficient in this amino acid, one of the most abundant in the bloodstream. However, as the body is subjected to undue stress shortages can occur, causing significant physiological distress ...
Youll find glutamine in many sports drinks and nutritional candy bars. The low dosages included in these products pose very little potential danger, but they also provide very little benefit. Depending on your training intensity, researchers recommend 8 to 20 grams of glutamine daily.. Clinical studies do not report any side effects at dosages as high as 21 grams, so you probably neednt worry when taking glutamine in moderate amounts ranging from 5 to 10 grams daily. However, because taking an excess of any one amino acid can cause an imbalance in your other amino-acid levels, to be on the safe side its best to combine your intake of glutamine with a complete chain of other amino acids. Rather than taking glutamine by itself, try mixing the powder into a protein drink or glass of juice. Glutamine also abounds in both vegetable and animal protein (meats, eggs, dairy, beans and some nuts), so unless youre training vigorously, a well-balanced diet will probably provide all the glutamine - and ...
Low prices on Glutamine! Glutamine provides great benefits for those under stress*. Glutamine (or L-Glutamine) is an amino acid best known to support recovery after exercise and to support overall health in many ways. L-Glutamine is also an important nutrient for brain, immune and intestinal cells. Dieting can also impair the bodys synthesis of glutamine.
What is the difference between Glutamine and Glutamate? Glutamine is a conditionally essential amino acid while Glutamate is a non-essential amino acid. It is..
Supplementary MaterialsSupplementary Table 1 Nutrient requirements. were divided into 2 groups: glutamine group (N=44) and non-glutamine group (N=47). We analyzed the rate of weight change, infection (clinically/microbiologically documented), complications (duration of mucositis and neutropenia, acute graft versus host disease), and 100-days mortality in each group. Results Regarding the clinical characteristics from the individuals, there have been no significant variations between your 2 organizations except that there is a larger percentage of myeloablative fitness routine in the glutamine group ( em P /em =0.005). In the glutamine group, the common amount of times of glutamine make use of, parenteral nourishment, and mucositis was 7.61.4, 14.69.9, and 13.39.5, respectively. Furthermore, multivariate evaluation revealed chances ratios of 0.37 (95% CI, 0.14C0.96; em P /em =0.042) and 0.08 (95% CI, 0.01C0.98; em P /em =0.048) for clinically documented disease and 100-days mortality, ...
Kaposis Sarcoma-Associated Herpesvirus (KSHV) is the etiologic agent of Kaposis Sarcoma, an endothelial-based tumor. Similarly to tumor cells, KSHV infected endothelial cells metabolize glucose preferentially through fermentation rather than oxidative phosphorylation, a process known as the Warburg effect. To support altered metabolism, tumor cells derive additional energy by hyperactiviating the conversion of glutamine to glutamate onto alpha-ketoglutarate, to enter into the TCA cycle and promote macromolecular biosynthesis. While it is known how glutamine is metabolized in tumor cells, glutamine metabolism in KSHV infected cells has not yet been explored. The Lagunoff lab has established that glucose is required during KSHV infection. In addition to glucose, I hypothesize that KSHV modulates glutamine utilization to sustain viral oncogenic infection. My project will focus on understanding how KSHV infected endothelial cells modulate both glucose and glutamine utilization and the cell ...
Glutamine has recently been the focus of much scientific interest. A growing body of evidence suggests that during certain stressful times, the body may require more Glutamine than it can produce. Under these circumstances Glutamine may be considere
Mediates the side-chain deamidation of N-terminal glutamine residues to glutamate, an important step in N-end rule pathway of protein degradation. Conversion of the resulting N-terminal glutamine to glutamate renders the protein susceptible to arginylation, polyubiquitination and degradation as specified by the N-end rule. Does not act on substrates with internal or C-terminal glutamine and does not act on non-glutamine residues in any position. Does not deaminate acetylated N-terminal glutamine. With the exception of proline, all tested second-position residues on substrate peptides do not greatly influence the activity. In contrast, a proline at position 2, virtually abolishes deamidation of N-terminal glutamine (By similarity ...
