Oxidative Stress Indicators

Septic liver injury/failure that is mainly characterized by oxidative stress, inflammation, and apoptosis led to a great part of terminal liver pathology with limited effective intervention. Here, we used a lipopolysaccharide (LPS) stimulation model to simulate the septic liver injury and investigated the effect of sophocarpine on LPS-stimulated mice with endotoxemia. We found that sophocarpine increases the survival rate of mice and attenuates the LPS-induced liver injury, which is indicated by pathology and serum liver enzymes. Further research found that sophocarpine ameliorated hepatic oxidative stress indicators (H2O2, O2∙−, and NO) and enhanced the expression of antioxidant molecules such as superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH). In addition, sophocarpine also attenuated regional and systematic inflammation and further reduced apoptosis of hepatocytes. Mechanistic evidence was also investigated in the present study as sophocarpine inhibited hepatic expression of the CYP2E/Nrf2 pathway during oxidative stress, inactivated p38/JNK cascade and NF-κB pathway, and, meanwhile, suppressed PI3K/AKT signaling that reduced apoptosis. Conclusively, the present study unveiled the protective role of sophocarpine in LPS-stimulated oxidative reaction, inflammation, and apoptosis by suppressing the CYP2E/Nrf2/ROS as well as PI3K/AKT pathways, suggesting its promising role in attenuating inflammation and liver injury of septic endotoxemia.

The effect of Watermelon (Citrullus lanatus) Pulp Juice (WPJ) on scopolamine (SCOP) induced memory deficits is due to the involvement of oxidative stress and AChE activity. The juice was obtained by crushing the pulp in blender and three different concentrations of 100%, 50% and 25% was administration to prevent memory deficit by evaluating changes of AChE activity and oxidative stress indicators (SOD, CAT, LPO and GPx) induced by scopolamine. These results provide evidence that WPJ is an alternative to protect SCOP induced memory deficits in mice by involvement of oxidative stress and AChE activity.

Abstract Hepatocellular carcinoma (HCC) accounts for more than 90% of primary liver cancers and is a major global health problem. The present application relates to normalizing abnormal levels of hematological blood parameters, oxidative stress indicators, and liver enzyme levels in the rats using melanin, and particularly, to treating their abnormal levels, in addition to evaluate the role of melanin during and after the progression of HCC, which will be supplemented histologically. Hematological blood parameters such as white blood cells (WBCs), red blood cells (RBCs), hemoglobin (HGB), hematocrit (HCT), and platelets (PLTs); liver enzymes such as alanine transaminase (ALT) and aspartate transaminase (AST); oxidative stress such as glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD); LP malondialdehyde (MDA) were evaluated in all groups of rats. Injection of Diethylnitrosamine (DEN) and 2-Acetyaminofluorine (2-AFF) induced HCC in the rats accompanied with a significant reduction in WBCs, RBCs, HGB, HCT, and PLTs, GSH-PX, and SOD; while a significant elevation was observed in ALT and AST, and MDA compared to the control. Melanin normalized all the above mentioned parameters during and after the progression of cancer towards their control values. These results demonstrate the beneficial use of melanin as a powerful antioxidant tool in inhibiting and treating HCC in the rats.

Oxidative Stress Indicators

We studied the alterations in oxidative stress indicators (hydrogen peroxide, superoxide radical, lipid peroxidation – LPO) and the alterations in the content of low molecular weight metabolites (ascorbic acid, glutathione, proline, chlorophyll and carotenoids) in the shoots of triticale (Triticosecale) under short-term (0-96 h) sodium chloride stress (120 mM) with statistical methods: principal component analysis (PCA) and cluster analysis. An analysis of the alterations in oxidative stress indicators allowed us to calculate the correlation coefficients for the pairs: peroxide – superoxide (0.52), peroxide – LPO (0.62), superoxide – LPO (0.23). The inclusion in the analysis of data on alterations in the content of low molecular weight antioxidants showed that the PCA method forms three main groups for all the studied characteristics: (1) LPO and hydrogen peroxide, (2) chlorophyll and carotenoids, (3) glutathione and ascorbate. The correlation coefficients were calculated for pairs: ascorbate – glutathione (0.71), ascorbate – proline (0.81), glutathione – proline (0.28). Such a value of the coefficient of the first pair suggests that ascorbic acid also performs numerous other functions, in addition to participating in the ascorbate-glutathione cycle. The high correlation between ascorbate and proline can be explained by the similar nature of alterations in their content in triticale shoots under conditions of short-term sodium chloride stress. Negative correlation coefficients in pairs of hydrogen peroxide – chlorophyll (-0.73), peroxide – carotenoids (-0.75), ascorbic acid – LPO (-0.70), LPO – proline (-0.69) give reason to talk about the possible protective role of photosynthesis pigments from accumulating hydrogen peroxide, as well as the potential role of ascorbic acid and proline in protecting membranes from lipid peroxidation. The application of the cluster analysis method showed that first and second order clusters between ascorbate, proline and glutathione reflect their known antioxidant role. The results obtained may also indicate that pigments have a much lower protective function.

Denv2 Infection

Dengue viruses (DENVs) cause dengue fever which is an important mosquito-borne disease in tropical areas. Generally, DENV does not cause cellular damage in mosquito cells. However, alterations in cytosolic calcium ions ([Ca2+]cyt) and the mitochondrial membrane potential (MMP), as well as accumulated reactive oxygen species (ROS), including superoxide anions (O2∙-) and hydrogen peroxide (H2O2), can be detected in C6/36 cells with DENV2 infection. Evident upregulation of BiP/GRP78 also appeared at 24 h postinfection in DENV2-infected C6/36 cells. As expression of BiP/GRP78 mRNA was reduced when the transcription factor X-box-binding protein-1 (XBP1) was knocked down in C6/36 cells, it demonstrated that BiP/GRP78 is the target gene regulated by the XBP1 signal pathway. We further demonstrated that the expression and splicing activity of XBP1 were upregulated in parallel with DENV2 infection in C6/36 cells. In C6/36 cells with BiP/GRP78 overexpression, oxidative stress indicators including [Ca2+]cyt, MMP,O2∙-, and H2O2were all pushed back to normal. Taken together, DENV2 activates XBP1 at earlier stage of infection, followed by upregulating BiP/GRP78 in mosquito cells. This regulatory pathway contributes a cascade in relation to oxidative stress alleviation. The finding provides insights into elucidating how mosquitoes can healthily serve as a vector of arboviruses in nature.
