Cardiomegaly in the juvenile visceral steatosis (JVS) mouse is reduced with acute elevation of heart short-chain acyl-carnitine level after L-carnitine injection. (1/1186)

The long-term administration of L-carnitine was very effective in preventing cardiomegaly in juvenile visceral steatosis (JVS) mice, which was confirmed by heart weight as well as the lipid contents in heart tissue. After i.p. injection of L-carnitine, the concentration of free carnitine in heart remained constant, although serum free carnitine level increased up to 80-fold. On the other hand, a significant increase in short-chain acyl-carnitine level in heart was observed. These results suggest that increased levels of short-chain acyl-carnitine, not free carnitine, might be a key compound in the protective effect of L-carnitine administration in JVS mice.  (+info)

Mutations in the organic cation/carnitine transporter OCTN2 in primary carnitine deficiency. (2/1186)

Primary carnitine deficiency is an autosomal recessive disorder of fatty acid oxidation caused by defective carnitine transport. This disease presents early in life with hypoketotic hypoglycemia or later in life with skeletal myopathy or cardiomyopathy. The gene for this condition maps to 5q31.2-32 and OCTN2, an organic cation/carnitine transporter, also maps to the same chromosomal region. Here we test the causative role of OCTN2 in primary carnitine deficiency by searching for mutations in this gene in affected patients. Fibroblasts from patients with primary carnitine deficiency lacked mediated carnitine transport. Transfection of patient's fibroblasts with the OCTN2 cDNA partially restored carnitine transport. Sequencing of the OCTN2 gene revealed different mutations in two unrelated patients. The first patient was homozygous (and both parents heterozygous) for a single base pair substitution converting the codon for Arg-282 to a STOP codon (R282X). The second patient was a compound heterozygote for a paternal 1-bp insertion producing a STOP codon (Y401X) and a maternal 1-bp deletion that produced a frameshift creating a subsequent STOP codon (458X). These mutations decreased the levels of mature OCTN2 mRNA and resulted in nonfunctional transporters, confirming that defects in the organic cation/carnitine transporter OCTN2 are responsible for primary carnitine deficiency.  (+info)

Mutations of OCTN2, an organic cation/carnitine transporter, lead to deficient cellular carnitine uptake in primary carnitine deficiency. (3/1186)

Systemic primary carnitine deficiency (CDSP, OMIM 212140) is an autosomal recessive disease characterized by low serum and intracellular concentrations of carnitine. CDSP may present with acute metabolic derangement simulating Reye's syndrome within the first 2 years of life. After 3 years of age, patients with CDSP may present with cardiomyopathy and muscle weakness. A linkage with D5S436 in 5q was reported in a family. A recently cloned homologue of the organic cation transporter, OCTN2, which has sodium-dependent carnitine uptake properties, was also mapped to the same locus. We screened for mutation in OCTN2 in a confirmed CDSP family. One truncating mutation (Trp132Stop) and one missense mutation (Pro478Leu) of OCTN2 were identified together with two silent polymorphisms. Expression of the mutant cDNAs revealed virtually no uptake activity for both mutations. Our data indicate that mutations in OCTN2 are responsible for CDSP. Identification of the underlying gene in this disease will allow rapid detection of carriers and postnatal diagnosis of affected patients.  (+info)

Study on propionyl-L-carnitine in chronic heart failure. (4/1186)

AIMS: In patients with chronic heart failure, fatigue is independent of haemodynamic and neuroendocrine changes and possibly may be due to impaired muscle metabolism. Propionyl-L-carnitine, a carnitine derivative, was shown in previous studies to improve muscle metabolism. The objective of this study was to evaluate the effect of propionyl-L-carnitine on exercise capacity in mild moderate chronic heart failure patients, treated with ACE inhibitors and diuretics. METHODS AND RESULTS: This was a phase III, double-blind, randomized, parallel, multicentre study. The primary objective was the evaluation of the effect of propionyl-L-carnitine vs placebo on maximum exercise duration using a bicycle exercise test. The primary analysis performed in the intention-to-treat population (271 and 266 patients in propionyl-L-carnitine and placebo), showed no statistically significant difference between treatments. A difference of 15 s in favour of propionyl-L-carnitine was observed in the completer/complier population (P=0.092). An a priori specified subgroup analysis on patients stratified by baseline maximum exercise duration showed a trend of improvement in propionyl-L-carnitine patients with shorter maximum exercise duration. A non a priori specified analysis in patients stratified by ejection fraction (< or = 30% vs 30-40%), showed a statistically significant difference in maximum exercise duration in favour of propionyl-L-carnitine in those patients with a higher ejection fraction (40 s, P<0.01). There were no safety issues. CONCLUSION: The study fails to meet the primary objective, but confirms the good safety profile of propionyl-L-carnitine. An exploratory non-prespecified analysis suggests that propionyl-L-carnitine improves exercise capacity in patients with preserved cardiac function. This hypothesis needs to be confirmed by a specific tailored study.  (+info)

Pharmacokinetic analysis of the cardioprotective effect of 3-(2,2, 2-trimethylhydrazinium) propionate in mice: inhibition of carnitine transport in kidney. (5/1186)

The site of action of 3-(2,2,2-trimethylhydrazinium) propionate (THP), a new cardioprotective agent, was investigated in mice and rats. I.p. administration of THP decreased the concentrations of free carnitine and long-chain acylcarnitine in heart tissue. In isolated myocytes, THP inhibited free carnitine transport with a Ki of 1340 microM, which is considerably higher than the observed serum concentration of THP. The major cause of the decreased free carnitine concentration in heart was found to be the decreased serum concentration of free carnitine that resulted from the increased renal clearance of carnitine by THP. The estimated Ki of THP for inhibiting the reabsorption of free carnitine in kidneys was 52.2 microM, which is consistent with the serum THP concentration range. No inhibition of THP on the carnitine palmitoyltransferase activity in isolated mitochondrial fractions was observed. These results indicate that the principal site of action of THP as a cardioprotective agent is the carnitine transport carrier in the kidney, but not the carrier in the heart.  (+info)

Decreased tissue distribution of L-carnitine in juvenile visceral steatosis mice. (6/1186)

We kinetically analyzed the disposition of L-carnitine of juvenile visceral steatosis (JVS) mice compared with that of normal mice to elucidate the mechanism of the systemic L-carnitine deficiency of JVS mice. There were significant differences in the plasma concentration-time course of total radioactive carnitine (L-[3H]carnitine, [acetyl-3H]carnitine, and other [acyl-3H]carnitines) between normal and JVS mice after a single i.v. or p.o. administration of L-[3H]carnitine (250 ng/kg). The oral bioavailability of L-[3H]carnitine in JVS mice (0.341) was about half of that in normal mice (0.675). The cumulative urinary excretion of total radioactive carnitine in JVS mice was about 10-fold more than that in normal mice, and the total clearance of unchanged L-[3H]carnitine for JVS mice (6.70 ml/min) was significantly higher than that for normal mice (2.45 ml/min). The distribution volume at the steady state of unchanged L-[3H]carnitine in JVS mice (1.10 liters/kg) was significantly smaller than that in normal mice (8.16 liters/kg). At 4 h after an i.v. administration, the apparent tissue-to-plasma concentration ratios of unchanged L-[3H]carnitine for various tissues of JVS mice, except for brain, were about one half to one 20th of those in normal mice. In conclusion, this in vivo disposition kinetic study of L-carnitine supports the previous in vitro finding that the L-carnitine transporter is absent or functionally deficient in JVS mice because the renal reabsorption, the intestinal absorption, and the apparent tissue-to-plasma concentration ratios in JVS mice are significantly lower than those in normal mice. The JVS mouse should be a useful experimental model for studying carnitine deficiency diseases.  (+info)

Comparisons of flux control exerted by mitochondrial outer-membrane carnitine palmitoyltransferase over ketogenesis in hepatocytes and mitochondria isolated from suckling or adult rats. (7/1186)

The primary aim of this paper was to calculate and report flux control coefficients for mitochondrial outer-membrane carnitine palmitoyltransferase (CPT I) over hepatic ketogenesis because its role in controlling this pathway during the neonatal period is of academic importance and immediate clinical relevance. Using hepatocytes isolated from suckling rats as our model system, we measured CPT I activity and carbon flux from palmitate to ketone bodies and to CO2 in the absence and presence of a range of concentrations of etomoxir. (This is converted in situ to etomoxir-CoA which is a specific inhibitor of the enzyme.) From these data we calculated the individual flux control coefficients for CPT I over ketogenesis, CO2 production and total carbon flux (0.51 +/- 0.03; -1.30 +/- 0.26; 0.55 +/- 0.07, respectively) and compared them with equivalent coefficients calculated by similar analyses [Drynan, L., Quant, P.A. & Zammit, V.A. (1996) Biochem. J. 317, 791-795] in hepatocytes isolated from adult rats (0.85 +/- 0.20; 0.23 +/- 0.06; 1.06 +/- 0.29). CPT I exerts significantly less control over ketogenesis in hepatocytes isolated from suckling rats than those from adult rats. In the suckling systems the flux control coefficients for CPT I over ketogenesis specifically and over total carbon flux (< 0.6) are not consistent with the enzyme being rate-limiting. Broadly similar results were obtained and conclusions drawn by reanalysis of previous data {from experiments in mitochondria isolated from suckling or adult rats [Krauss, S., Lascelles, C.V., Zammit, V.A. & Quant, P.A. (1996) Biochem. J. 319, 427-433]} using a different approach of control analysis, although it is not strictly valid to compare flux control coefficients from different systems. Our overall conclusion is that flux control coefficients for CPT I over oxidative fluxes from palmitate (or palmitoyl-CoA) differ markedly according to (a) the metabolic state, (b) the stage of development, (c) the specific pathway studied and (d) the model system.  (+info)

Replenishment and depletion of citric acid cycle intermediates in skeletal muscle. Indication of pyruvate carboxylation. (8/1186)

The effects of various substrates on the concentrations of free amino acids, citric acid cycle intermediates and acylcarnitines were studies in perfused hindquarter of rat in presence of glucose and insulin in order to assess regulatory mechanisms of the level of citric acid cycle intermediates in skeletal muscle. 1. Acetate and acetoacetate effected a significant increase in the level of citrate cycle intermediates and accumulation of acetylcarnitine. These changes were accompanied by a reduction in the level of alanine. The concentration of AMP was significantly elevated. 2. Muscle mitochondria fixed 14CO2 in the presence of pyruvate. The products were identified as malate or citrate when whole and disintegrated mitochondria were used respectively. The fixation was greatly stimulated by acetylcarnitine. 3. Acetylcarnitine inhibited the production of pyruvate from malate by muscle mitochondria. 4. Perfusion with 2-oxoisocaproate and 2-oxoisovalerate promoted increases in the level of citric cycle intermediates, a drop in both alanine and glutamate, and accumulation of branched-chain acylcarnitines. 2-Oxoisocaproate also caused a reduction of alanine released from the muscle. 5. Perfusion with leucine and valine did not change the concentration of citric acid cycle intermediates, but elevated glutamate and still more the concentration of alanine. 6. It is concluded that citric cycle intermediate level in the perfused resting muscle is modified by a) conditions which change the concentration of acetyl-CoA and thereby modify the rate of pyruvate carboxylation and decarboxylation of malate via malic enzyme b) conditions which change the concentration of pyruvate cause changes in alanine and cycle intermediates in the same direction via transamination reactions c) conditions which change the concentrations of 2-oxoacids which are converted to cycle intermediates via oxidation.  (+info)

Systemic primary carnitine deficiency (SPCD), also known as carnitine uptake defect, carnitine transporter deficiency (CTD) or systemic carnitine deficiency is an inborn error of fatty acid transport caused by a defect in the transporter responsible for moving carnitine across the plasma membrane. Carnitine is an important amino acid for fatty acid metabolism. When carnitine cannot be transported into tissues, fatty acid oxidation is impaired, leading to a variety of symptoms such as chronic muscle weakness, cardiomyopathy, hypoglycemia and liver dysfunction. The specific transporter involved with SPCD is OCTN2, coded for by the SLC22A5 gene located on chromosome 5. SPCD is inherited in an autosomal recessive manner, with mutated alleles coming from both parents. Acute episodes due to SPCD are often preceded by metabolic stress such as extended fasting, infections or vomiting. Cardiomyopathy can develop in the absence of an acute episode, and can result in death. SPCD leads to increased ...

A total of 59 gilts were used to determine the effects of supplemental L-carnitine on reproductive performance. Experimental treatments were arranged in a 2 × 3 factorial with main effects of L-carnitine (0 or 50 ppm) and day of gestation (40, 55, or 70). All gilts received a constant feed allowance of 3.86 lb/day and a top-dress containing either 0 or 88 mg of L-carnitine, starting on the first day of breeding and continuing until the day of harvest. Total litter size, total litter weight, and crown-to-rump length of fetuses were not different (P,0.10) between treatments at any gestation length. By d 70 of gestation, average fetus weight was heavier (P = 0.06) for fetuses from gilts fed L-carnitine, compared with fetuses from gilts fed the control diet. In addition, at d 70, fetal insulin-like growth factor- II (IGF-II) concentrations were lower (P = 0.09) for fetuses from gilts fed L-carnitine than for fetuses from gilts fed the control diet. Feeding L-carnitine may have decreased fetal ...
The introduction of Highly Active AntiRetroviral Therapy (HAART) for AIDS and HIV has improved survival considerably. However, HIV patients treated with HAART show significant metabolic symptoms, such as lipodystrophy, dyslipidemia, and insulin resistance. A possible contribution to these dysmetabolic symptoms in HIV/HAART is a decrease in mitochondrial function, resulting in a decreased fatty acid oxidation. Life style modulation such as aerobic exercise and L-carnitine supplementation may be beneficial to mitochondrial function. Aerobic exercise improves the biogenesis and function of mitochondria. A combined regime of aerobic and resistance training has been demonstrated to increase lean body mass and reduce overall fat and truncal fat and the levels of triglyceride and LDL cholesterol. L-Carnitine plays an important role in the transfer of long-chain acyl groups into the mitochondrial matrix and potentially improves energy metabolism. Further, L-carnitine supplementation decreases serum ...

Vegetarian athletes generally eat better than their meat-eating counterparts, but there are some nutrients (e.g. vitamin B12) that they lack including one crucial amino acid that is key to muscle performance and recovery: carnitine.. Normally, carnitine is supplied in meat and dairy products, items that vegetarians usually avoid unless they are ovo-lacto (able to consume eggs and dairy) (1, 2). Blood concentrations of carnitine in vegetarians are reported to be strikingly low or around 20-30 percent lower than their meat-eating counterparts and suggests that tissue carnitine stores in the body are also low in concentration (3).. Unfortunately, lower carnitine intake in vegetarians has received relatively little attention (4). But the role carnitine plays in the body is one of heavy involvement in energy metabolism and cellular protection. Additionally, 95 percent of the bodys carnitine is found in muscle tissue.. Carnitine supplementation is shown to correct low concentrations and support ...

This study was conducted to determine the effect on semen quality traits of supplementing the diets of Iraqi drakes with L-carnitine. Forty eight male Iraqi ducks, 30 weeks old, were randomly allocated to four treatments with 12 drakes per treatment group, replicated three times, with four drakes per replicate. The treatment groups consisted of birds fed a diet free of L-carnitine (T1, control group); birds fed a diet containing 50 mg L-carnitine/kg diet (T2); birds fed a diet containing 100 mg L-carnitine/kg diet (T3); and birds fed a diet containing 150 mg L-carnitine/kg diet. The drakes were fed the experimental diets only during the experimental period, which lasted three months. The semen quality traits that were investigated were ejaculate volume, mass and individual motility of spermatozoa, spermatocrit, spermatozoa ...
L-carnitine is concentrated in the epididymis, where sperm mature and acquire their motility (86). Two uncontrolled trials of L-carnitine supplementation in more than 100 men diagnosed with decreased sperm motility found that oral L-carnitine supplementation (3 grams/day) for three to four months significantly improved sperm motility (87, 88). However, no information on subsequent fertility was reported. A cross-sectional study of 101 fertile and infertile men found that L-carnitine concentrations in semen were positively correlated with the number of sperm, the percentage of motile sperm, and the percentage of normal appearing sperm in the sample (89), suggesting that L-carnitine levels in semen may be useful in evaluating male infertility. More recently, a placebo-controlled,double-blind, cross-over trial in 86 patients with male infertility found that L-carnitine (2 grams/day) supplementation for two months led to significantly improvements in sperm quality, evidenced by increases in sperm ...
Without carnitine, fats cannot be burned for energy. This explains the fascination with carnitine supplementation as a fat burner. In two separate studies, supplementation of carnitine (3 grams per day) for 10 days resulted in significantly higher rates of fat oxidation (1,2). This work was recently validated by researchers in the United Kingdom (3). They studied healthy endurance-trained men who supplemented with 80 grams of carbohydrate 2 times per day for 24 weeks. One group also received 2 grams l-carnitine l-tartrate (LCLT) in their carbohydrate beverage. Resting muscle carnitine was unchanged after 12 weeks but increased by 21% after 24 weeks in the carnitine group. When the carnitine group exercised at a low intensity after 24 weeks of supplementation, they showed the higher muscle carnitine was linked to significant muscle glycogen sparing (55% less) compared to controls. Work output was 35% greater than controls. Several lines of evidence support a role of carnitine in other processes ...
The acylcarnitines in plasma and blood spots of 23 patients with proven deficiency of long-chain 3-hydroxyacylcoenzyme A dehydrogenase were reviewed. Long-chain 3-hydroxyacylcarnitines of C14:1, C14, C16 and C18:1 chain length, and long-chain acylcarnitines of C12, C14:1, C14, C16, C18:2 and C18:1 chain length were elevated. Acetylcarnitine was decreased. In plasma, elevation of hydroxy-C18:1 acylcarnitine over the 95th centile of controls, in combination with an elevation of two of the three acylcarnitines C14, C14:1 and hydroxy-C16, identified over 85% of patients with high specificity (less than 0.1% false positive rate). High endogenous levels of long-chain acylcarnitines in normal erythrocytes reduced the diagnostic specificity in blood spots compared with plasma samples. The results were also diagnostic in asymptomatic patients, and were not influenced by genotype. Treatment with diet low in fat and high in medium-chain triglyceride decreased all disease-specific acylcarnitines, often to normal,
Raising your carnitine levels will fight this visceral fat gain because it increases fat burning, which has the effect of taking triglycerides and low-density lipoproteins out of the system so that they dont build up causing high cholesterol and atherosclerosis. A new research study in the journal Food and Chemical Toxicology illustrates this. Researchers gave a carnitine supplement to mice who were fed a high-fat diet in order to make them gain weight. In comparison to a group of mice fed a placebo, the carnitine group gained substantially less visceral and subcutaneous fat (fat that is right below the surface of the skin that you can pinch with your fingers). The placebo group exhibited the beginning stages of non-alcoholic fatty liver disease and atherosclerosis, neither of which were evident in the carnitine group ...

L-Carnitine L Carnitine deficiency has been identified in some dogs with dilated cardiomyopathy. Unfortunately we know from animal models that carnitine deficiency can be created by making the heart beat at very rapid heart rate (using a pacemaker); we also know that very rapid heart rates are common in dogs with DCM. Therefore the carnitine deficiency that was reported in earlier years may be the result of, rather than the cause of, DCM. So while we had all hoped that carnitine supplementation would resolve or prevent DCN in dogs, unfortunately it hasn’t. Many people choose to supplement L-carnitine in the diets of dogs with DCM and it is not likely to cause them any harm, but it is costly and may not be of any real benefit. Boxers with DCM should get 2-3 grams every 12 hours. If you want to supplement a Cocker Spaniel with DCM, the recommended dose is 1 gram of L-carnitine every 12 hours. DO NOT GIVE D-CARNITINE OF D,L-CARNITINE.. Taurine In the late 1980s taurine deficiency was ...
The conversion of 6-N-[Me-14C]trimethyl-lysine into carnitine and 4-N-trimethylaminobutyrate (butyrobetaine) was demonstrated in rats kept on a lysine-deficient diet. After the rats were given [14C]trimethyl-lysine for 4 days, a total of 17% of the injected label was recovered as carnitine from carcass and urine extracts. Another 8% of the trimethyl-lysine label was converted into 4-N-trimethylaminobutyrate, most of which was recovered from the urine. The conversion of trimethyl-lysine into the above two metabolites supports the pathway of carnitine biosynthesis as lysine+methionine → 6-N-trimethyl-lysine → 4-N-trimethylaminobutyrate → carnitine. In addition, three other metabolites representing 2% of the injected dose were recovered. Only an insignificant portion of the label was recovered as free trimethyl-lysine from the carcass, whereas 22% of the injected label was recovered in the urine. A relatively low specific radioactivity in carnitine was found when ...

L-carnitine is concentrated in the epididymis, where sperm mature and acquire their motility (86). Two uncontrolled trials of L-carnitine supplementation in more than 100 men diagnosed with decreased sperm motility found that oral L-carnitine supplementation (3 grams/day) for three to four months significantly improved sperm motility (87, 88). However, no information on subsequent fertility was reported. A cross-sectional study of 101 fertile and infertile men found that L-carnitine concentrations in semen were positively correlated with the number of sperm, the percentage of motile sperm, and the percentage of normal appearing sperm in the sample (89), suggesting that L-carnitine levels in semen may be useful in evaluating male infertility. More recently, a placebo-controlled,double-blind, cross-over trial in 86 patients with male infertility found that L-carnitine (2 grams/day) supplementation for two months led to significantly improvements in sperm quality, evidenced by increases in sperm ...
This case study suggest that CoQ deficiency and the concomitant significant reductions in complex I, I+III, and II+III enzymatic activities in respiratory chain (RC) were responsable for the mitochondrial disorders observed in this patient. The observed muscle carnitine deficiency is most likely related to an increased reduced nicotinamide adenine dinucleotide-nicotinamide adenine dinucleotide ratio associated with respiratory chain defects. The increased ratio could impair beta-oxidation at the level of 3-hydroxyacyl- coenzyme A dehydrogenases, with a subsequent accumulation of acyl-coenzyme A beta-oxidation intermediates. These intermediates, released as carnitine esters, are transported into plasma and eliminated in urine, leading to secondary carnitine deficiency ...
New research by the Cleveland Clinic has found another reason why consuming a lot of red meat increases your risk of heart disease. Researchers are now convinced that the association between red meat and arteriosclerosis is more complex than just consuming bad fat. A chemical compound in red meat called carnitine, and the type of gut bacterial flora that you have also play an important role.. Large amounts of diet sourced carnitine are found in red meats and pork. For most people, dietary carnitine isnt necessary since your liver and kidneys also produce carnitine from the amino acids lysine and methionine.. How Does Dietary Carnitine Increase Your Risk Of Heart Disease?. The cardio health problems associated with dietary carnitine comes when certain bacteria in your intestines convert it into a chemical called trimethylamine-N-oxide or TMAO. TMAO is known to increase your risk of developing arteriosclerosis or clogged arteries that can lead to heart attacks and death.. By eating large amounts ...
Carnitine is a natural substance that the body uses to process fats and produce energy. Carnitine deficiency is when not enough of the nutrient carnitine is available to cells in the body. This can cause muscle weakness and heart or liver problems.
We determined the effects of supplemental L-carnitine on the insulin-like growth factor (IGF) system in porcine embryonic myoblasts (PEM) from gilts. Forty gilts (BW = 303.6 lb) were allotted to 1 of 4 treatments that were arranged in a 2 × 2 factorial, with main effects of L-carnitine (0 or 50 ppm) and day of gestation (55 or 70). All gilts were fed 3.86 lb/day and a top-dress containing either 0 or 50 ppm of L-carnitine, starting on the first day of breeding and continuing through the allotted gestation length. At d 55 or 70 of gestation, fetuses were removed for isolation of PEM from the hind-limb muscles. Real-time quantitative PCR was used to determine growth factor messenger RNA (mRNA) expression in cultured PEM at 72-, 96-, 120-, and 144-h after plating. Flow cytometry was used to analyze percentage of myogenic cells with a myoblast/myotube specific monoclonal antibody 5.1H11, and for determination of cell cycle stage. There was no treatment differences (P,0.10) for the expression of ...

April 11, 2013 A study published in Nature Medicine claims that carnitine, a compound abundant in red meat, sold as a dietary supplement, and present in some energy drinks, may increase the risk of heart disease. Carnitine typically helps the body transport fatty acids into cells to be used as energy. But researchers at the Cleveland Clinic found that in both humans and mice, certain bacteria in the digestive tract convert carnitine to another metabolite, called TMAO, which promotes atherosclerosis, or a thickening of the arteries. The researchers tested the carnitine and TMAO levels of omnivores, vegans, and vegetarians, and examined records of 2,595 patients undergoing cardiac evaluations. In patients with high TMAO levels, the more carnitine in their blood, the more likely they were to develop cardiovascular disease, heart attacks, stroke, and death. The researchers speculated that carnitine could be compounding the danger. "Cholesterol is still needed to clog the arteries, but TMAO changes ...

Intestinal microbiota metabolism of choline and phosphatidylcholine produces trimethylamine (TMA), which is further metabolized to a proatherogenic species, trimethylamine-N-oxide (TMAO). We demonstrate here that metabolism by intestinal microbiota of dietary l-carnitine, a trimethylamine abundant in red meat, also producesTMAO and accelerates atherosclerosis in mice. Omnivorous human subjects produced more TMAO than did vegans or vegetarians following ingestion of l-carnitine through a microbiota-dependent mechanism. The presence of specific bacterial taxa in human feces was associated with both plasma TMAO concentration and dietary status. Plasma l-carnitine levels in subjects undergoing cardiac evaluation (n = 2,595) predicted increased risks for both prevalent cardiovascular disease (CVD) and incident major adverse cardiac events (myocardial infarction, stroke or death), but only among subjects with concurrently high TMAO levels. Chronic dietary l-carnitine supplementation in mice altered ...

This Pilot study follows up on a publication entitled A novel X-linked inborn error of carnitine biosynthesis and a neuronal carnitine pathway hypothesis for autism. This paper describes a new genetic condition (called TMLHE deficiency) that results in the loss of ability to make carnitine in the body.
Effective evaluation or prediction of therapy response could be helpful for treatment of chronic kidney disease (CKD), which may rely on accurate biomarkers. Acylcarnitines are involved with lipid metabolism and mitochondrial function. The relation of acylcarnitines with treatment response in patients with CKD is unknown. The purpose of this study is to investigate the association of plasma acylcarnitines with renal function and its alteration by intervention in patients with IgA nephropathy (IgAN). A retrospective study was performed in 81 IgAN patients with treatment by traditional Chinese medicine (TCM). Multivariate linear regression analyses were performed to identify the association of acylcarnitines with baseline estimated glomerular filtration rate (eGFR) and eGFR changes after treatment. Twenty-seven acylcarnitines were measured at baseline and after 1-year TCM intervention. Certain short-chain and median-chain acylcarnitines were independently associated with baseline eGFR and eGFR alterations

The researchers examined the records of 2,595 meat eaters and vegetarians undergoing cardiac evaluations and found that patients with high levels of TMAO were more likely to develop cardiovascular disease and suffer heart attacks, strokes and death.. Dr. Stanley Hazen, chief of cellular and molecular medicine at Lerner, said carnitine may be compounding the negative effects of the cholesterol and saturated fat found in beef, pork and other red meat.. However, Dr. Betsy Booren, chief scientist at the American Meat Institute, noted that cardiovascular disease is "a complex condition" thats associated with a number of factors, from genetics to lifestyle, and attempts to link it to "a single compound found at safe levels in red meat oversimplifies" the issue.. Many other studies examining carnitine have not shown adverse effects at a number of doses, she said, adding that a fact sheet from the National Institutes of Health concludes that carnitine is essential and safe.. In fact, Hazen said some ...

L-Carnitine is known to improve blood sugar levels and sperm production, lower cholesterol, counteract symptoms of hyperthyroidism and fight heart disease. Since L-carnitine demonstrates antioxidant activity, it is sometimes used as a complementary therapy in treating various conditions related to oxidative stress, most notably heart disease and angina. In fact, The American Journal of Cardiology reports that this nutrient permits angina patients to exercise more with less pain and also to reduce medication levels. A few studies indicate that carnitine may also permit heart failure patients to experience similar results.. L-carnitine (the CAS No. is 541-15-1) also plays a role in preserving bone density. Unfortunately, this nutrient becomes less concentrated in bone along with osteocalcin, a protein secreted by osteoblasts that is involved in bone mineralization. In fact, these deficiencies are the main factors that contribute to osteoporosis in postmenopausal women. Studies have shown that this ...

BACKGROUND.l-Carnitine, an abundant nutrient in red meat, accelerates atherosclerosis in mice via gut microbiota-dependent formation of trimethylamine (TMA) and trimethylamine N-oxide (TMAO) via a multistep pathway involving an atherogenic intermediate, γ-butyrobetaine (γBB). The contribution of γBB in gut microbiota-dependent l-carnitine metabolism in humans is unknown. METHODS. Omnivores and vegans/vegetarians ingested deuterium-labeled l-carnitine (d3-l-carnitine) or γBB (d9-γBB), and both plasma metabolites and fecal polymicrobial transformations were examined at baseline, following oral antibiotics, or following chronic (≥2 months) l-carnitine supplementation. Human fecal commensals capable of performing each step of the l-carnitine→γBB→TMA transformation were identified. RESULTS. Studies with oral d3-l-carnitine or d9-γBB before versus after antibiotic exposure revealed gut microbiota contribution to the initial 2 steps in a metaorganismal l-carnitine→γBB→TMA→TMAO ...
Mechanisms mediating the cardioprotective actions of glucagon-like peptide 1 (GLP-1) were unknown. Here, we show in both ex vivo and in vivo models of ischemic injury that treatment with GLP-1(28-36), a neutral endopeptidase-generated (NEP-generated) metabolite of GLP-1, was as cardioprotective as GLP-1 and was abolished by scrambling its amino acid sequence. GLP-1(28-36) enters human coronary artery endothelial cells (caECs) through macropinocytosis and acts directly on mouse and human coronary artery smooth muscle cells (caSMCs) and caECs, resulting in soluble adenylyl cyclase Adcy10-dependent (sAC-dependent) increases in cAMP, activation of protein kinase A, and cytoprotection from oxidative injury. GLP-1(28-36) modulates sAC by increasing intracellular ATP levels, with accompanying cAMP accumulation lost in sAC-/- cells. We identify mitochondrial trifunctional protein-α (MTPα) as a binding partner of GLP-1(28-36) and demonstrate that the ability of GLP-1(28-36) to shift substrate ...

What Does This Mean?. Changes in metabolites may be a response to altered biochemical pathways due to disease (Jones 2010). We believe that a change in our patients acylcarnitine profiles is a useful indicator of changes in their metabolic states. Monitoring these changes in our patients could be an opportunity to advance understanding of the mechanism of their diseases, finding new biomarkers, or new therapies.. The formation of acylcarnitines is important not only in the metabolism of fatty acids but is also an important pathway in the mechanism of the ketogenesis. Carnitine could also be involved in a host of other pathways by consequence of its free hydroxyl group. It has been suggested that L-carnitine can complex with various other metabolites and carboxylic acids of varying lengths to transport them throughout the body for a variety of functions (Jones 2010).. Our Focus. In some research circles it is believed that changes in the concentration of carnitine can be used to identify changes ...

Our son, Carter was born on January 20, 2009, with no apparent health problems except reflux. He always lagged in his milestones, even early in his life, but doctors assured us that he was just a little behind and would catch up. Throughout the first year of his life, he struggled with head and trunk control, reflux and respiratory infections. When he was admitted at 10 months old for a respiratory infection, we were finally referred to a neurologist to address his developmental delays and abnormal carnitine levels. That is when mitochondrial disease was brought up for the first time. We were referred to a Genetics Counselor from there, and that is when the process of testing began.. In Atlanta, in May of 2011, after two muscle biopsies, a spinal tap, MRIs, EKGs, EEGs, RMR and many more tests, we received his official diagnosis of Complex I mitochondrial disease. For our son, his brain and gastrointestinal tract are effected the most. He still struggles with dysmotility, constipation, reflux, ...

L-carnitine is essential for the transport of fatty acids into the heart muscle and mitochondria for energy production and is sensitive to the level of oxygen in the heart muscle. Studies have shown that patients with CHF who take L-carnitine have improved ejection fraction (Goa KL et al 1987; Mancini M et al 1992; Pucciarelli G et al 1992). There is evidence that L-carnitine helps the heart by preventing the enlargement of the left ventricle, which is a critical step in the progression of CHF. Studies have shown that L-carnitine can help prevent left ventricular enlargement after bypass surgery in patients who have had a heart attack (Taggart DP et al 1996). The same results were found among patients who have had an acute heart attack (Colonna P et al 2000). By improving ejection fraction and preventing enlargement of the left ventricle, L-carnitine addresses two of the most serious problems associated with CHF ...

acylcarnitine; carnitine; carnitine palmitoyltransferase; chronic fatigue syndrome; fatty acid. Abstract. Reuter SE, Evans AM (School of Pharmacy & Medical Sciences, University of South Australia, Adelaide, SA, Australia; Sansom Institute for Health Research, University of South Australia, Adelaide, SA, Australia). Long-chain acylcarnitine deficiency in patients with chronic fatigue syndrome. Potential involvement of altered carnitine palmitoyltransferase-I activity. J Intern Med 2011; 270: 76-84.. Objective. The underlying aetiology of chronic fatigue syndrome is currently unknown; however, in the light of carnitines critical role in mitochondrial energy production, it has been suggested that chronic fatigue syndrome may be associated with altered carnitine homeostasis. This study was conducted to comparatively examine full endogenous carnitine profiles in patients with chronic fatigue syndrome and healthy controls.. Design. A cross-sectional, observational study.. Setting and subjects. ...
The potent anti-hyperuricemia activities of Fructus Gardenia Extract (FGE) have been well reported. The aim of this study was to evaluate the uricosuric and nephro-protective effects of FGE and explore its possible mechanisms of action in oxonate-induced hyperuricemic mice. FGE was orally administered to hyperuricemic and normal mice for 1 week. Serum and urinary levels of uric acid, creatinine and blood urea nitrogen (BUN), and fractional excretion of uric acid (FEUA) were measured. The mRNA and protein levels of mouse urate transporter 1 (mURAT1), glucose transporter 9 (mGLUT9), ATP-binding cassette, subfamily G, 2 (mABCG2), organic anion transporter 1 (mOAT1), mOAT3, oncoprotein induced transcript 3 (mOIT3), organic cation/carnitine transporters in the kidney were analyzed. Simultaneously, Tamm-Horsfall glycoprotein (THP) levels in urine and kidney were detected. FGE significantly reduced serum urate levels and increased urinary urate levels and FEUA in hyperuricemic mice. It could also effectively
Transporters influence the disposition of chemicals within the body by participating in absorption, distribution, and elimination. Transporters of the solute carrier family (SLC) comprise a variety of proteins, including organic cation transporters (OCT) 1 to 3, organic cation/carnitine transporters (OCTN) 1 to 3, organic anion transporters (OAT) 1 to 7, various organic anion transporting polypeptide isoforms, sodium taurocholate cotransporting polypeptide, apical sodium-dependent bile acid transporter, peptide transporters (PEPT) 1 and 2, concentrative nucleoside transporters (CNT) 1 to 3, equilibrative nucleoside transporter (ENT) 1 to 3, and multidrug and toxin extrusion transporters (MATE) 1 and 2, which mediate the uptake (except MATEs) of organic anions and cations as well as peptides and nucleosides. Efflux transporters of the ATP-binding cassette superfamily, such as ATP-binding cassette transporter A1 (ABCA1), multidrug resistance proteins (MDR) 1 and 2, bile salt export pump, multidrug ...
Jerry Vockley and Inform Network describe everything you want to know about CACT deficiency, a rare fatty acid oxidation disorder. Read more about its symptoms and some developing treatments.
Dodecanedioic acid is a dicarboxylic acid which is water soluble and involves in a metabolic pathway intermediate to those of lipids and carbohydrates. (PMID 9591306). Dodecanedioid acid is an indicator of hepatic carnitine palmitoyltransferase I (CPT IA) deficiency. CPT IA deficiency is characterized by hypoketotic dicarboxylic aciduria with high urinary levels of dodecanedioic acid. This C12 dicarboxylic aciduria suggests that carnitine palmitoyltransferase I may play a role in the uptake of long-chain dicarboxylic acids by mitochondria after their initial shortening by beta-oxidation in peroxisomes. (PMID: 16146704 ...
Our study has confirmed that the most important criterion for the detection of MCAD deficiency is the presence in the blood spot of octanoylcarnitine at a concentration , 0.3 μM (in this study , 0.38 μM). However, we have also shown that blood spot octanoylcarnitine concentrations are higher in neonates with MCAD deficiency and that there is an association between low octanoylcarnitine and low free carnitine. There are two possible explanations for the latter association. The first is that the volume of blood in the 6 mm disc was substantially less than 10 μl or that the elution was much less efficient for this group of blood spots. We consider this to be very unlikely; all the Guthrie cards that were received were made from approved brands of filter paper, all blood spots were inspected visually to make sure that the 6 mm disc was completely filled, and a standardised procedure was adopted for the elution step. The second and more likely explanation for the association is that these patients ...

Very long-chain acyl-CoA dehydrogenase deficiency (VLCAD) is a rare genetic condition resulting from a mutation (change) in a persons DNA. Due to this change, people with VLCAD have problems breaking down certain fats properly. VLCAD occurs when the body either does not make enough or makes non-working enzyme called very long-chain acyl-CoA dehydrogenase. Enzymes are proteins that help break down the food we eat into the pieces our body can use for energy. In this case, the job of the VLCAD enzyme is to break down the very long-chain fatty acids, which are parts of the fat from our food. These fatty acids are important energy sources when there are not enough sugars in the body, such as in between meals. A person with VLCAD cannot use this type of fatty acid for energy because it cant break it down. This also causes a build-up of too many unused very long-chain fatty acids, which can be harmful to the body.. Those affected by VLCAD can show symptoms any time between infancy and adulthood. ...
