chicken liver glutamate dehydrogenase

Q Hu, U Agarwal, B J Bequette
We aimed to quantify the rate of gluconeogenesis (GNG), non-essential amino-acid (NEAA) synthesis, and substrate partitioning to the Krebs cycle in embryonic (e) day e14 and e19 chicken embryos. An in ovo continuous tracer infusion approach was employed to test the hypotheses that GNG and NEAA synthesis in developing chicken embryo increases from e14 to e19. [(13)C6]Glucose or [(13)C3]glycerol was continuously infused (8 h) into the chorio-allantoic compartment of eggs on e14 and e19. Glucose entry rate, Cori cycling, and GNG were higher (P < 0...

In the present study, clinical chemistry was applied to assess the pathogenesis and progression of experimentally induced inclusion body hepatitis (IBH). For this, five fowl aviadenovirus (FAdV) strains from recent IBH field outbreaks were used to orally inoculate different groups of day-old specific pathogen-free chickens, which were weighed, sampled and examined during necropsy by sequential killing. Mortalities of 50% and 30% were recorded in two groups between 6 and 9 days post-infection (dpi), along with a decreased weight of 23% and 20%, respectively, compared to the control group...

Cathepsin L, a lysosomal protein in mouse embryonic stem cells has been shown to clip the histone H3 N- terminus, an activity associated with gene activity during mouse cell development. Glutamate dehydrogenase (GDH) was also identified as histone H3 specific protease in chicken liver, which has been connected to gene expression during aging. In baker's yeast, Saccharomyces cerevisiae, clipping the histone H3 N-terminus has been associated with gene activation in stationary phase but the protease responsible for the yeast histone H3 endopeptidase activity had not been identified...

Site-specific proteolysis of the N or C-terminus of histone tails has emerged as a novel form of irreversible post-translational modifications assigned to histones. Though there are many reports describing histone specific proteolysis, there are very few studies on purification of a histone specific protease. Here, we demonstrate a histone H3 specific protease (H3ase) activity in chicken liver nuclear extract. H3ase was purified to homogeneity and identified as glutamate dehydrogenase (GDH) by sequencing. A series of biochemical experiments further confirmed that the H3ase activity was due to GDH...

Clipping of histone tails has been reported in several organisms. However, the significance and regulation of histone tail clipping largely remains unclear. According to recent discoveries H3 clipping has been found to be involved in regulation of gene expression and chromatin dynamics. Earlier we had provided evidence of tissue-specific proteolytic processing of histone H3 in White Leghorn chicken liver nuclei. In this study we identify a novel activity of glutamate dehydrogenase (GDH) as a histone H3-specific protease in chicken liver tissue...

Glutamate dehydrogenase (GDH) enzyme is recently being reported to be present in the nucleus in addition to the mitochondria in a number of organisms. Here we investigated the distribution of GDH in liver and brain tissues of chicken. Polyclonal anti-GDH antibody against bovine GDH was raised by us, which was later shown to be immunereactive to chicken GDH. The nuclear and the mitochondrial extracts from liver and brain tissues of chicken were made as described. By quantitative immunoreactivity, it was revealed that the nuclear GDH expressed in comparable efficiencies in the liver and brain...

Chickens aged 6 weeks were inoculated intravenously with two strains of Newcastle disease virus: a mesogenic strain (MAJ) with relatively high neurotropism and a lentogenic strain (V5K7E1). The levels of several enzymes were determined in serum and in various tissues of the infected birds. A marked increase in lactic dehydrogenase (LDH) level in skeletal muscles and a decrease of LDH activity in liver were found in chickens infected with the MAJ strain. Differentiation of LDH isoenzymes by either heating or electrophoresis indicated a significant elevation of LDH 5 iso-enzyme in breast muscle and of LDH 1 in leg muscle, while the activity of LDH 1 in liver decreased...

Data on the effects of Plasmodium gallinaceum on domesticated fowl are sparse, justifying a full investigation of its pathology. Clinical signs following blood-induced infections with the Wellcome line of strain 8A included depression, fever, anorexia, reduced weight gain, poor feed conversion, anaemia, green faeces and often death. After administration of 10(6) erythrocytic parasites, mortality 5 to 10 days after infection was 10% to 93% in chickens 7 to 84 days old. The older the birds, the lower the mortality and the longer the time to death...

Recently, we have reported a novel tropomyosin (TM) -binding protein, glutamate dehydrogenase (GDH) and demonstrated by affinity column chromatography that chicken liver TM interacts with GDH in an ATP-dependent manner. To elucidate the physiological roles of the interaction between TM and GDH, we performed co-sedimentation assays of TM and GDH with F-actin, because it is known that TM exerts its physiological functions by associating with actin filaments. The results showed that TM and GDH co-pelleted with F-actin...

Aflatoxin B(1) (AFB(1)) negatively affects chicken (Gallus domesticus) growth. This effect is more severe during development. We studied the influence of age on the toxic effects of AFB(1) on plasma, renal and hepatic enzymes, under two protocols, in adult and in developing Arbor-Acres chickens. Protocol A: 100 male 4-week-old chickens (640 g), received AFB(1), 0.5, 1.0, or 2.0 microg/g of feed (daily p.o.), a fourth group received an aflatoxin-free diet. Five birds/group were slaughtered at 7, 14, 21 and 28 days of treatment...

Profiles of plasma enzymes were compared in two strains of single comb white leghorn laying hens, a normal commercial strain and strain UCD-003, which is highly susceptible to fatty liver-hemorrhagic syndrome. Plasma activity of lactate dehydrogenase (LDH), glutamate dehydrogenase (GDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatine kinase (CK) averaged 194 +/- 27, 4.0 +/- 2.8, 146 +/- 20, 1.0 +/- 1.0, and 1041 +/- 268 U/liter, respectively in normal birds. Activities of LDH, GDH, AST, and ALT, but not CK, were significantly higher in UCD-003 than in normal hens...

The present studies were undertaken to characterise oxidative metabolism with diverse substrates in hepatic mitochondria of acidotic chicks. Metabolic acidosis was experimentally induced by replacement of drinking water with ammonium chloride solution (15 g/l) for 5 d. State 3 oxidation rates in liver mitochondria were significantly reduced in acidotic chicks only for pyruvate and glutamate as substrates requiring complex I, III and IV of the electron transport chain, while they were not changed for either succinate-requiring complexes II, III and IV, ascorbate+TMPD-requiring complex IV, or alpha-ketoglutarate requiring complexes I, III and IV...

In a first experiment, 28 specific pathogen-free chickens aged 3 weeks showed clinical signs 1 to 5 days after intramuscular inoculation with Erysipelothrix rhusiopathiae. Twelve of 28 birds died 2 to 4 days after inoculation. Macroscopically, the liver, spleen and kidneys were seen to be enlarged and congested. Histologically, fibrinous thrombus formation, seen in the hepatic sinusoids, renal glomerular capillaries and small pulmonary blood vessels, was a characteristic feature. In addition, the liver showed marked congestion, increase of mononuclear cells and heterophils in the sinusoids, hyperplasia of sinusoidal lining cells, and vacuolar changes in hepatic cells...

Ross male broiler chickens were used to determine the effect of dietary energy on metabolism following a 6-day dietary energy restriction. Chickens were fed an amount of food (10 g) from 6 to 12 days of age calculated to only maintain body weight (maintenance energy) and not support appreciable growth. The chickens were then fed 1, 2, or 4x this amount of food for the period from from 13 to 21 days of age. Another group of chickens were also restricted from 6 to 12 days of age, but on an ad libitum basis from days 12 to 21...

The hepatic glycine cleavage system in the chicken was examined at different stages of development to study regulation of its biosynthesis. Embryonic levels of polypeptide and mRNA for glycine decarboxylase, one of the three intrinsic components of this enzyme system, were approximately 10% of their adult levels and were rapidly increased following hatching. Those of H-protein, another intrinsic component, were somewhat higher and were more slowly increased throughout the course of development. The change in activities of the two components went with the increase in their polypeptide levels...

Succinate dehydrogenase activity was measured in rat pancreatic islet homogenates incubated in the presence of [1,4-14C]succinate, the reaction velocity being judged through the generation of 14CO2 in the auxiliary reactions catalysed by pig heart fumarase and chicken liver NADP-malate dehydrogenase. In the presence of 1.0 mM succinate, the reaction velocity averaged 5.53 +/- 0.44 pmol min-1 microgram-1 islet protein. The Km for succinate was close to 0.4 mM and the enzymic activity was restricted to mitochondria...

1. The two molecular forms of mitochondrial malate dehydrogenase are partly bound to the mitochondrial membranes. 2. The A form is located on the outer surface of the inner mitochondrial membrane and also in the intermembrane space. 3. The B form of the enzyme appears in the matrix and bound in part, probably, to the inner surface of the inner mitochondrial membrane. 4. Glutamate dehydrogenase, glutamate oxaloacetate transaminase, fumarase and lactate dehydrogenase are bound, to a greater or lesser extent, to the mitochondrial membranes, the fumarase having the highest degree of binding...
