Evidence is presented suggesting that the increased uptake of amino acids by the liver of rats fed on high-protein diets is obtained by developing favourable Cited by:

    Nonalcoholic fatty liver disease (NAFLD) is a serious health problem in developed countries. We documented the effects of feeding with a NAFLD-inducing, methionine- and choline-deficient (MCD) diet, for 1–4 weeks on rat liver oxidative stress, with respect to a control diet. Glycogen, neutral lipids, ROS, peroxidated proteins, and SOD2 were investigated using histochemical Cited by:   Excess iron modulates endoplasmic reticulum stress-associated pathways in a mouse model of alcohol and high-fat diet-induced liver injury Terrence C H Tan 1, 2, 3 Darrell H G Crawford 1, 2.

      The objective of this study was to determine the effects of creatine supplementation on liver biomarkers of oxidative stress in exercise-trained rats. Forty day-old adult male Wistar rats were assigned to four groups for the eight-week experiment. Control group (C) rats received a balanced control diet; creatine control group (CCr) rats received a balanced diet Cited by:   Evidence is presented suggesting that the increased uptake of amino acids by the liver of rats fed on high-protein diets is obtained by developing favourable gradients and enhancing transport capacities. These adaptations allow sufficient amounts of amino acids to enter the liver, where accelerated metabolism plays a decisive role. PMCID: PMCCited by:

Response of liver proteins to dietary and physiological stress in the rat by Margaret Carol Cheney Download PDF EPUB FB2

Abstract. The influence of prolonged protein deprivation followed by protein repletion in the adult male rat upon liver neutral glycerides and cholesterol was studied.

Neutral glyceride and cholesterol concentrations increased for 8 weeks. Thereafter neutral glycerides decreased to normal and cholesterol to below normal after 14 weeks of Cited by: This immunohistochemical study was performed to analyze the distribution of three stress proteins (HSP25, HSP72, GRP75) in rat kidney and liver orally exposed to.

Further dynamic proteomic research used fluorescence difference gel electrophoresis, found 42 changed proteins in the liver of chronic restraint stress rats, and validated 3 proteins to suggest how functional proteins act on metabolites to produce energy and process materials in rat liver as it responds to restraint stress.

Our previous study has demonstrated that long-term stress, known as chronic stress (CS), can aggravate nonalcoholic fatty liver disease in high-fat diet (HFD)-fed rat. In this study, we tried to figure out which lipid metabolic pathways were impacted by CS in the HFD-fed rat.

Accordingly, deficiency or excessive production of most dietary nutrients can impair the balance between the anti- and pro-oxidant agents, also causing liver by: stress proteins reaction against Al. Stress proteins are a superfamily of proteins, called heat-shock proteins (HSP) and glucose-regulated proteins (GRP), highly conserved from procariotes to mammals.

Major members are commonly expressed in the kidney and liver under physiological conditions but play a cytoprotective role during adverse conditions.
