Abstract

The aim of this study was to analyze the liver injury and oxidative stress in an experimental model of Metabolic Syndrome (MS) induced by chronic administration of a sucrose-rich diet (SRD) and to evaluate the effects of chia seed as a therapeutic strategy. Male Wistar rats were fed with a reference diet (RD) -6 months- or a SRD -3 months. Then, the latter group was randomly divided into two subgroups. One subgroup continued receiving the SRD for up to 6 months and the other was fed with a SRD where whole chia seed was incorporated as a source of dietary fat for the next 3 months (SRD+CHIA). The results showed that rats fed with a SRD for a long period of time developed dyslipidemia, hyperglycemia, hepatic lipid accumulation, liver injury, hepatic lipid peroxidation and oxidative stress. Hepatic NrF2 expression was significantly decreased. In addition, a significant increase in hepatic NFκB p65 expression and a positive correlation of this with plasma TNFα levels were found. The administration of chia seed for 3 months reversed dyslipidemia, hyperglycemia, lipid accumulation, liver injury, lipid peroxidation and oxidative stress. In the liver tissue, NrF2 expression was normalized and NFκB p65 expression was decreased, the latter was associated with a decrease in plasma TNFα levels. The present study showed new aspects of liver damage, lipid peroxidation and oxidative stress in dyslipidemic insulin resistant rats chronically fed with a sucrose-rich diet. However, we demonstrated new properties and molecular mechanisms associated with the beneficial anti-oxidant effects of chia seed consumption.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
