Objective(s): Gallic acid (GA) is a highly effective antioxidant, which its beneficial effects are well known, but its impact on expression of microRNAs (miRs) following hepatic ischemia-reperfusion (I/R) is not well recognized. Therefore, the current research was designed to specify the beneficial effect of GA on miRs (122 and 34a), liver functional tests, and histopathological alterations bey...
We characterized the effects of calorie restriction (CR) on the expression of key glycolytic, gluconeogenic, and nitrogen-metabolizing enzymes in mice. Of the gluconeogenic enzymes investigated, liver glucose-6-phosphatase mRNA increased 1.7- and 2.3-fold in young and old CR mice. Phospho enolpyruvate carboxykinase mRNA and activity increased 2.5- and 1.7-fold in old CR mice. Of the key glycoly...
Initiating mechanisms that impair gluconeogenic enzymes and spare lipogenic enzymes in diet-induced obesity (DIO) are obscure. Here, we examined insulin signaling to Akt and atypical protein kinase C (aPKC) in liver and muscle and hepatic enzyme expression in mice consuming a moderate high-fat (HF) diet. In HF diet-fed mice, resting/basal and insulin-stimulated Akt and aPKC activities were dimi...
It is now well established that major changes in hepatic fatty acid degradation occur at birth and at weaning. Thus the rate of oxidation of [14C]palmitate by liver preparations increases rapidly after birth and decreases on weaning (Lockwood & Bailey, 1970; Bailey & Lockwood, 1973). Similar changes are observed with regard to theconcentration of ketone bodies in the blood (Lockwood &Bailey, 19...
Background: Gentamicin is an aminoglycosides antibiotic which is used to treat several types of bacterial infections. The aim of this study was to evaluate the effects of Nigella sativa L. extract (NSE) on liver toxicity and serum level of liver enzymes in rats induced by gentamicin. Methods: In the present experimental study, 42 Wistar male rats were divided randomly into 6 groups includes: c...
Background: Probiotics have attracted a great attention aiming to develop natural non-toxic antioxidants, because of their role in decreasing the risk of reactive oxygen species (ROS) accumulation. Objectives: The purpose of this study was to assess the antioxidant activity of a probiotic Streptococcus salivarius ssp thermophillus (St.sa) and to evaluate its protective effect against the ...
Hepatic function of 80 children aged under 3 years with Plasmodium vivax malaria were studied during the acute attack and 6 weeks after antimalarial treatment. Raised levels of serum aspartate transaminase (serum AST; SGOT), serum alanine transaminase (serum ALT; SGPT), and alkaline phosphatase were observed in 68%, 39% and 46% of cases respectively. AST levels were higher than ALT ones and the...
Nitric-oxide synthase, the enzyme responsible for mammalian nitric oxide generation, and cytochrome P450, the major enzymes involved in drug metabolism, share striking similarities. Therefore, it makes sense that cytochrome P450 drug mediated biotransformations might play an important role in the pharmacological modulation of nitric oxide synthase. In this work, we have undertaken an integrated...
The synthesis of nucleotides in the body is centrally controlled by the liver, via salvage or de novo synthesis. We reveal a pervasive circadian influence on hepatic nucleotide metabolism, from rhythmic gene expression of rate-limiting enzymes to oscillating nucleotide metabolome in wild-type (WT) mice. Genetic disruption of the hepatic clock leads to aberrant expression of these enzymes, toget...
We report the synthesis of aramide nanoparticles containing a chiral N-phthaloyl valine moiety and their antioxidant activities on hepatic contents of cytochrome P₄₅₀, amidopyrene N-demethylase, aniline-4-hyroxylase and induced the hepatic content of cytochrome b5 and nicotinamide adenine dinucleotide phosphate (NADPH) cytochrome C-reductase. Polymers were obtained as well-separated spherical n...
