Lipid And Protein Oxidation

It has been proposed that there is a correlation between high-fat diet (HFD), oxidative stress and decreased γ-aminobutyric acid (GABA) levels, but this has not been thoroughly demonstrated. In the present study, we determined the effects of strawberry extract intake on the oxidative stress and GABA levels in the frontal cortex (FC) of obese rats. We observed that an HFD increased lipid and protein oxidation, and decreased GABA levels. Moreover, UV-irradiated strawberry extract (UViSE) decreased lipid peroxidation but not protein oxidation, whereas non-irradiated strawberry extract (NSE) reduced protein oxidation but not lipid peroxidation. Interestingly, NSE increased GABA concentration, whereas UViSE was not as effective. In conclusion, our results suggest that an HFD increases oxidative damage in the FC, whereas strawberry extract intake may ameliorate the disturbances associated with HFD-induced oxidative damage.

Markers Of Oxidative Stress

Purpose: This study was aimed to evaluate the antioxidant and anti-inflammatory effects of vitamin D and Simvastatin (SIM) on a high-fat diet (HFD) induced-obese rats. Methods: 40 adult male rats were divided into four groups: control group, HFD, HFD + vitamin D, and HFD + SIM for 14 weeks. Vitamin D or SIM supplementation was done for the last 6 weeks. Vitamin D dosage was 500 IU/kg, while SIM dosage was 10 mg/kg. Interleukin-6 (IL-6) concentration and markers of oxidative stress including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione(GSH) concentrations in serum were determined using ELISA kits and spectrophotometry methods, respectively. Results: Treatment with vitamin D or SIM could significantly reduce IL-6 and MDA and increases SOD, GPx activities, and GSH levels. Oxidative stress can result not only from increased ROS production but also from dysfunctional antioxidant defenses. Conclusion: From the experimental results, it was observed that SIM and vitamin D could attenuate oxidative stress and inflammation markers associated with obesity.

Abstract. The effects of instant cooked rice made from a combination of white rice and pigmented giant embryonic Keunnunjami rice, in comparison with those of instant regular white or brown rice and instant non-pigmented giant embryonic brown rice, on the glucose metabolism and antioxidant defense status in high-fat diet-fed mice were investigated. 56 male C57BL/6N mice were randomly divided into 7 dietary groups: normal control, high fat (23 %, HF), and HF supplemented with normal white (HF + NW) or brown rice (HF + NB), non-pigmented giant embryonic rice (HF + GB), and white rice with 8 % Keunnunjami (HF + KJ8) and 18 % Keunnunjami (HF + KJ18). After 7 weeks, HF mice showed marked increases in blood glucose (156 mg/dL), plasma insulin (12.1 mg/mL), and lipid peroxidation, and a significant decrease in hepatic glycogen (14.2 mg/g) relative to the control group (p < 0.05). However, addition of instant NB, GB, KJ8, andKJ18) rice suppressed this high-fat diet-induced hyperglycemia and oxidative stress through altering glucose-regulating enzymes (glucokinase, glucose-6-phosphatase, and phosphoenolpyruvate carboxykinase) and activation of antioxidant enzymes (superoxide dismutase, glutathione peroxidase, catalase, glutathione reductase, and paraoxonase). Compared with HF mice, HF + KJ8 and HF + KJ18 groups exhibited significantly lower glucose (139–141 mg/dL), insulin (10.6–10.9 mg/mL), and lipid peroxidation and higher glycogen (15.3–16.4 mg/g) (p < 0.05). The hypoglycemic and antioxidant effects of instant KJ8 and KJ18 rice were generally comparable to those of instant NB and GB rice. These findings illustrate that instant rice made from white rice with 8 % Keunnunjami rice may be useful as a functional food with therapeutic potential against hyperglycemia and oxidative damage.

And Oxidative Stress

While we continue to refine our understanding of the pathophysiology of bipolar disorder (BD), several hypotheses have been postulated including a role for monoamines, gamma-amino butyric acid, glutamate, and second messenger signaling pathways. Recently, mitochondrial dysfunction and oxidative stress have been identified by a number of studies, as an important etiological factor in this disorder. Mitochondria play a crucial role in ATP production through oxidative phosphorylation, a process carried out by the electron transport chain (ETC) complexes. During the transfer of electrons along this ETC, the ROS can be generated, especially in complex I and III4. Growing body of evidence suggests the association of mitochondrial dysfunction and BD. Recent DNA microarray analysis in post-mortem frontal cortex and hippocampus revealed that the expression of several mRNAs coding for ETC complexes I-V subunits was decreased in subjects with BD. Supporting the key involvement of oxidative damage in BD, assays conducted with peripheral blood samples have demonstrated that BD is associated with alterations in antioxidant enzymes and increased lipid peroxidation. Recently we found that oxidative damage to lipid is present in the frontal cortex of BD subjects. A meta-analysis suggested that the levels of lipid peroxidation are elevated in BD providing support for oxidative stress hypothesis of BD. Furthermore, BD subjects showed increased DNA damage, as well as, upregulation of apoptotic genes. These data not only suggest that oxidative mechanisms may form unifying common pathogenic pathways in psychiatric disorders, but also introduce new targets for the development of therapeutic interventions.

The objective of this study was to investigate the antioxidant capability and preventive effect of probiotics on high fat diet induced oxidative damage. Thirty male rats were randomly divided into three groups.The control group consumed a normal standard diet (5% fat, w:w), the high fat diet group received a high fat diet (20% fat, w:w), and probiotics group received a high fat diet supplemented with 2% probiotics. After 6 weeks, antioxidant capability of liver was determined and DNA fragmentation of liver cell was determined using a comet assay. The results showed that high fat diet could induce oxidative stress, shown as significant increases in lipid peroxidation and nitric oxide free radical, significant decrease in activities of superoxide dismutase and glutathione peroxidase, the percentage of DNA fragmentation was markedly increased, compared with control group. These alterations were significantly reversed in probiotics supplemented group and had no significant difference in antioxidant capability, lipid peroxidation and DNA damage compared with control group. Present observation indicated the probiotics had antioxidant property, which could scavenge free radical and enhance antioxidant defense system, and had the positive protective function on oxidative damage.
