Sublethal behavioral and biochemical toxicity of cypermethrin in juvenile Oreochromis niloticus in a static bioassay

Sublethal behavioral and biochemical toxicity of cypermethrin in Oreochromis niloticus (L.) juveniles was accessed under static conditions at concentrations of 0.5, 1.1, and 2.1 µg L−1 for up to eight weeks. The juveniles were highly sensitive to cypermethrin, with a 96-h LC50 of 12 µg L−1. Biphasic trends were noted for four avoidance behaviors: loss of equilibrium; erratic swimming; air gulping; opercular ventilation. Dose- and duration-dependent increases occurred in mucus secretion and color change. Mixed trends were noted for mean glutamate pyruvate transaminase, triglycerides, proteins, and cholesterol. These parameters decreased significantly depending on dose and duration in weeks two and six, but they increased in week eight. Mean glucose and glutamic oxaloacetic transaminase increased significantly depending on dose and duration up to week eight. No differences in glucose were noted in the control in week two. The findings of the present study confirmed that cypermethin adversely affected the health of fish even at a sublethal level.

A non-canonical convergence of carbohydrate and glutamine metabolism is required after metabolic rewiring in 3D environment

The fate of pyruvate, which is modulated mitochondrial pyruvate carrier (MPC) activity, is a defining metabolic feature in many cancers. Diffuse large B-cell lymphomas (DLBCLs) are a genetically and metabolically heterogenous cancer. Although MPC expression and activity differed between DLBCL subgroups, mitochondrial pyruvate oxidation was uniformly minimal. Mitochondrial pyruvate was instead robustly consumed by glutamate pyruvate transaminase 2 to support α-ketoglutarate production as part of glutamine catabolism. This led us to discover that glutamine exceeds pyruvate as a carbon source for the TCA cycle, but, MPC function is required to enable GPT2-mediated glutamine catabolism. Furthermore, we found that MPC inhibition only decreased DLBCL proliferation in a solid culture environment, but not in a suspension environment. Thus, the non-canonical connection between the consumption and assimilation of carbohydrates and glutamine in DLBCLs enables their proliferation in a solid 3D environment.

Nutritional Status of Tuberculosis Patients in Against Serum Glutamate Pyruvate Transaminase Levels

Background: Treatment of Tuberculosis patients are given in the form of a drugs combination. Some drugs which are Pyrazinamide, Isoniazid and Rifampicin can provide hepatotoxic side effects. Specific sign of hepatotoxic occurrence is increasing in the Serum Glutamate Pyruvate Transaminase levels. One of factors that influence hepatotoxicity is nutritional status. This study aims to determine the relationship between nutritional status and levels of Serum Glutamate Pyruvate Transaminase in tuberculosis patients.Methods: A non-experimental correlation study, retrospective approach with total sampling method, according to inclusion and exclusion criteria.

Serum Levels of Glutamate-Pyruvate Transaminase, Glutamate-Oxaloacetate Transaminase and Gamma-Glutamyl Transferase in 1494 Patients with Various Genotypes for the Alpha-1 Antitrypsin Gene

Background: Patients with liver disease associated with alpha-1 antitrypsin deficiency (AATD) are homozygous for the Z mutation, leading to chronic liver damage. Objective: To assess the serum levels of glutamate-oxaloacetate transaminase (GOT), glutamate-pyruvate transaminase (GPT), and gamma-glutamyl transpeptidase (GGT) in patients with different genotypes for the alpha-1 antitrypsin (AAT) gene. Methods: Patients (n = 1494) underwent genotyping of the SERPINA1 gene, together with a determination of AAT and GOT and GPT and GGT transaminase levels. Patients with a deficient allele (n = 476) and with a normal genotype were compared. Results: A statistically significant association was found between deficient genotypes and GOT (p < 0.0003), GPT (p < 0.002), and GGT (p < 0.006). Comparing GOT levels in patients with PI*Z deficient variant versus those with normal genotype, an odds ratio (OR) of 2.72 (CI: 1.5–4.87) (p < 0.0005) was obtained. This finding was replicated with the PI*Z allele and the GPT values (OR = 2.31; CI: 1.45–3.67; p < 0.0003). In addition, a statistically significant association was found between liver enzymes and AAT values. Conclusion: The PI*Z allele seemed to be a risk factor for the development of liver damage. AAT deficient genotypes were associated with GOT, GPT, and GGT altered values. Low AAT levels were associated with high GPT and GGT levels.

ALANINE AMINO TRANSFERASE (ALT) SPECIFIC ACTIVITIES IN LONG TERM SYSTEMIC HYPOXIC RAT BRAIN TISSUES

Background: Brain as a very aerobic organ is sensitive to hypoxia. Energy scarcities must be overcome by gluconeogenesis, which uses alanine or lactate as starting material. The reaction is catalyzed by alanine amino transaminase (ALAT or ALT), also known as glutamate pyruvate transaminase (GPT). Objective: To investigate whether the specific activities of alanine aminotransferase (ALT) increased in hypoxic rat brain.Methods: This experimental study used rats exposed to systemic normobaric hypoxia during 14 days. A group of 5 rats was sacrificed in days 1, 3, 7 and 14. The specific activities of ALT were analyzed in their brains using a reaction coupled with lactate dehydrogenase (LDH) activities.Results: The ALT specific activities in rat brain were very low. There was no significant increase of specific activities during long term hypoxia (p > 0.05).Conclusion: The rat brain ALT has no role in gluconeogenesis.

THE BENEFIT EFFECT OF GINGER SUPPLEMENTATION AGAINST NICKEL-INDUCED HEPATOTOXICITY IN ALBINO WISTAR RATS

Objective: This study was performed to study the potential capacity effect of ginger on the modulation effects of nickel-induced hepatotoxicity. Methods: Thirty-two female albino Wistar rats were divided into four groups of eight each. One served as a control group, the second group (Gi) received ginger 20 g/kg diet, while the third group (Ni) was given nickel 800 mg/L in their drinking water as NiSO46H2O and the fourth group (Ni+Gi) was treated daily with both nickel and ginger. The experiment was lasted for 21 days. Results: The exposure to nickel led to a significant decrease in body weight and food intake with an increase of liver weight. Nickel treatment also produced oxidative liver injury characterized by an increase of glucose, cholesterol, triglyceride, total lipids, bilirubin, malondialdehyde (MDA) concentrations and glutamate-pyruvate transaminase, glutamic oxaloacetic transaminase, and alkaline phosphatase activities. Meanwhile, serum total proteins and liver reduced glutathione (GSH) levels, catalase, GSH peroxidase, and GSH superoxide dismutase activities were decreased. These results are substantiated with marked changes in the histopathology, whereas the supplementation of ginger resulted in a restoration of the previous parameters. Conclusion: It seems that ginger supplementation is a potent factor for reducing the oxidative severity of nickel hepatotoxicity through its antioxidant action.
