Natural compounds have been found to modulate glutathione levels and function beyond their role as mere antioxidants. For example, certain compounds can upregulate the expression of glutathione-related enzymes, increase the availability of cysteine, the limiting amino acid for glutathione synthesis, or directly interact with glutathione and modulate its function.

This vitamin is capable of exerting antioxidant and anti-inflammatory activities, and acting as immunomodulators. Despite these well-known biological activities, the findings regarding the ability of vitamin E and its serum metabolites to prevent and/or control chronic disease are often conflicting and inconsistent.

These effects vary from the occasional simple sunburn to conditions resulting from chronic exposure such as skin aging and cancers. Secondary metabolites from the plant kingdom, including phenolic compounds, show relevant photoprotective activities.

A diet rich in fruits and vegetables can help to reduce the incidence of colorectal cancer thanks to the phenolic compounds, which possess antimutagenic and anticarcinogenic properties. Polyphenols, alongside their well-known antioxidant properties, also show a pro-oxidative potential, which makes it possible to sensitize tumor cells to oxidative stress.

Particular features in the pulp of blood oranges are marked levels of anthocyanin, a class of polyphenolic compounds well known to exert numerous health-promoting actions on human wellbeing including anti-obesity effects. In this study, we investigated , the antioxidant and anti-adipogenic activities of Morosil, a standardised extract of Moro blood oranges. During adipocyte differentiation, 3T3-L1 cells were treated with concentrations of extract containing 2.

Brain and other nervous system cancers are the 10th leading cause of death worldwide. Genome instability, cell cycle deregulation, epigenetic mechanisms, cytoarchitecture disassembly, redox homeostasis as well as apoptosis are involved in carcinogenesis. A diet rich in fruits and vegetables is inversely related with the risk of developing cancer.

View Article and Find Full Text PDFType 1 diabetes mellitus (T1D) is a chronic autoimmune disease resulting in the destruction of insulin producing β-cells of the pancreas, with consequent insulin deficiency and excessive glucose production. Hyperglycemia results in increased levels of reactive oxygen species (ROS) and nitrogen species (RNS) with consequent oxidative/nitrosative stress and tissue damage. Oxidative damage of the pancreatic tissue may contribute to endothelial dysfunction associated with diabetes.

This cluster of metabolic abnormalities comprises insulin resistance, increased levels of free fatty acids, hypercholesterolemia, obesity, hyperglycemia and hypertension, diabetes mellitus (DM) type 1 (T1DM) and type 2 (T2DM) along with DM-induced complications. Most of them are included in the well-known metabolic syndrome (MS).

HO-1 induction and/or activation is able to counterbalance, at least in part, oxidative stress and inflammation. For this reason, HO-1 can be regarded as an attractive target to ameliorate different stress-related pathologies.
