The impact of red grape juice (Vitis labrusca)consumption associated with physical training on oxidative stress, inflammatory and epigenetic modulation in healthy elderly women.

Abstract
The imbalance of epigenetic, oxidative stress and inflammatory markers is associated with the aging physiopathology. Then, the influence of bioactive nutritional compounds and physical training on these biomarkers has been studied, although the combination of both strategies has been not investigated. Therefore, our aim was to verify the effect of the association of physical training with red grape juice (Vitis labrusca) consumption on global histone acetylation H3 and H4 levels, oxidative stress markers and interleukin 6 (IL-6) levels in peripheral blood of healthy elderly women. This double-blind randomized clinical study consisted of 29 volunteers, aged 59 years and over, divided into three groups: grape juice group (GJG, n = 9); placebo and exercise group (PLEG, n = 10) and grape juice and exercise group (GJEG, n = 10). During 1 month, GJG consumed 400 ml of grape juice per day (integral and conventional), while the PLEG and GJEG groups, besides consuming juice or placebo were submitted to a concurrent physical training protocol (two times per week, 60 min / session). The volunteers were submitted to blood collections before and after the intervention for the biomarkers analysis, e.g. IL-6, histone acetylation H3 and H4, lipid oxidative damage (TBARS), proteins (Carbonyl), non-enzymatic antioxidant defense (Sulfhydryl groups) and activity of antioxidant enzymes (superoxide dismutase and catalase). There were no statistically significant differences in the global levels of histone acetylation H3 and H4 post intervention compared to the basal period as well and between groups were found. However, PLEG and GJEG showed a remarkable reduction on IL-6 levels after intervention. We also observed an increase in Carbonyl levels, SOD activities and Sulfhydryl levels comparing before and after intervention. Considering the interaction of time and groups, a significant increase in Sulfhydryl levels only in GJG was found. The physical training protocol associated or not with grape juice consumption showed anti-inflammatory effects and an influence in the antioxidant defenses (non enzymatic and enzymatic) in elderly women. However in grape juice group, without exercise, we observed an increase in non enzymatic antioxidant defense, what could be attributed to the polyphenols content. These responses seem not to be involved with histone acetylation status.

Front Physiol 2020; 11:451.

Abstract
Neuromuscular diseases (NMDs) are a group of often severely disabling disorders characterized by dysfunction in one of the main constituents of the motor unit, the cardinal anatomic-functional structure behind force and movement production. Irrespective of the different pathogenic mechanisms specifically underlying these disease conditions genetically determined or acquired, and the related molecular pathways involved in doing that, oxidative stress has often been shown to play a relevant role within the chain of events that induce or at least modulate the clinical manifestations of these disorders. Due to such a putative relevance of the imbalance of redox status occurring in contractile machinery and/or its neural drive in NMDs, physical exercise appears as one of the most important conditions able to positively interfere along an ideal axis, going from a deranged metabolic cell homeostasis in motor unit components to the reduced motor performance profile exhibited by the patient in everyday life. If so, it comes out that it would be important to identify a proper training program, suitable for load and type of exercise that is able to improve motor performance in adaptation and response to such a homeostatic imbalance. This review therefore analyzes the role of different exercise trainings on oxidative stress mechanisms, both in healthy and in NMDs, also including preclinical studies, to elucidate at which extent these can be useful to counteract muscle impairment associated to the disease, with the final aim of improving physical functions and quality of life of NMD patients.
