The usefulness of supplementary dietary L-carnitine as an immunomodulator to increase antigen-specific antibody levels was analysed in 2-6-week-old broilers. The chickens received commercial feeds either unsupplemented (starter feed 17.8 mg carnitine/kg, finisher diet 22.9 mg carnitine/kg) or supplemented with L-carnitine (100 mg carnitine/kg added to feed). At 14 d of age, both groups were dis...
To examine the kinetics of carnitine palmitoyltransferase-I (CPT-I) and the influence of dietary variables, young pigs (18 kg, n 5 20) were fed corn-soybean meal diets supplemented with 40 g soy oil/kg and containing either 136 or 180 g crude protein/kg and either 0 or 500 mg/kg L-carnitine (2 3 2 factorial design). Diets were offered for 10 d (85% of ad libitum); CPT-I activities in liver and ...
Primary carnitine deficiency is caused by the defective OCTN2 carnitine transporter encoded by the SLC22A5 gene. A lack of carnitine impairs fatty acid oxidation resulting in hypoketotic hypoglycemia, hepatic encephalopathy, skeletal and cardiac myopathy, and arrhythmia. This condition can be detected by finding low levels of free carnitine (C0) in neonatal screening. Mothers with primary carni...
This study was carried out to investigate the effects of in ovo feeding of L-carnitine and Satureja Khuzistanica extract on hatchability, post-hatch performance and carcass traits in broiler chickens. A total of 560 fertile eggs of Ross 308 strain (36-wk-old breeder flock) were assigned randomly to seven treatments with four replicates and 20 eggs per replicate. Treatments included control grou...
background: the aim of the study was to compare the radioprotective efficacy in the kidney of l-carnitine to that of amifostine. materials and methods: thirty three-month-old wistar albino rats were randomly assigned to four groups: group 1 (control); group 2 (irradiation alone); group 3 (amifostine plus irradiation); and group 4 (l-carnitine before irradiation). the rats in groups 2, 3, and 4...
The effects of carnitine on the metabolism of palmitoylcarnitine were studied by using isolated rat liver mitochondria. Particular attention was given to carnitine acyltransferase-mediated interactions between carnitine and the mitochondrial CoA pool. Carnitine concentrations less than 1.25mm resulted in an increased production of acetylcarnitine during palmitoylcarnitine oxidation. Despite thi...
BACKGROUND In the present study, we tested the hypothesis that carnitine supplementation counteracts obesity-induced muscle fiber transition from type I to type II. METHODS 24 obese Zucker rats were randomly divided into two groups of 12 rats each (obese control, obese carnitine) and 12 lean Zucker rats were selected for lean control group. A control diet was given to both control groups and ...
BACKGROUND L-Carnitine has been demonstrated to ameliorate cachectic symptoms. In the present study, we sought to investigate the role of the peroxisome proliferator-activated receptor-γ (PPAR-γ) signaling pathway in the ameliorative effects of L-carnitine on cancer cachexia in a colon-26 tumor-bearing mouse model. METHODS The cachectic mice received L-carnitine (p.o.) or etomoxir (i.p.), or ...
Carnitine is a small molecule widely present in all cells from prokaryotic to eukaryotic. It is an important element in β-oxidation of fatty acids. Carnitine is a scavenger of oxygen free radicals in mammalian tissues. Lack of carnitine in a hemodialysis patient can lead to carnitine deficiency. Oxidation of fatty acids and lipid metabolism are severly affected by carnitine deficiency. Oxidativ...
BACKGROUND In rodents and pigs, it has shown that carnitine synthesis and uptake of carnitine into cells are regulated by peroxisome proliferator-activated receptor α (PPARA), a transcription factor which is physiologically activated during fasting or energy deprivation. Dairy cows are typically in a negative energy balance during early lactation. We investigated the hypothesis that genes of ca...
