Abstract:

The prevalence of ischemic stroke in metabolic syndrome (MetS) is continually increasing and produces a great impact on both qualities of life and annual healthcare budget. Due to the efficiency limitation of the current therapeutic strategy, the poor availability of polyphenol substances induced by the first pass effect and the beneficial effects of mulberry fruit and ginger on brain and MetS-related diseases together with the synergistic concept, the neuroprotective effect against ischemic stroke in MetS condition of phytosome containing the combined extract of mulberry fruit and ginger (PMG) has been considered. To explore the neuroprotective effect and possible underlying mechanism of PMG on brain damage in cerebral ischemic rat with MetS, male Wistar rats were induced MetS by high-carbohydrate high-fat diet (HCHF) for 16 weeks and subjected to the cerebral ischemia/reperfusion injury (CIRI) at the right middle cerebral artery (Rt. MCAO). PMG at doses of 50, 100, and 200 mg/kg were orally fed with for 21 days, and they were assessed brain damage, neurological deficit score, and the changes of oxidative stress markers, inflammatory markers, PPARexpression, and epigenetic modification via DNMT-1 were performed. All doses of PMG significantly improved brain infarction, brain edema, and neurological deficit score. In addition, the reduction in DNMT-1, MDA level, NF-B, TNF, and C-reactive protein together with the increase in SOD, CAT, and GPH-Px activities, and PPARexpression in the lesion brain were also observed. The current data clearly revealed the neuroprotective effect against cerebral ischemia with MetS condition. The possible underlying mechanism might occur partly via the suppression of DNMT-1 giving rise to the improvement of signal transduction via PPARresulting in the decreasing of inflammation and oxidative stress. In conclusion, PMG is the potential neuroprotectant candidate against ischemic stroke in the MetS condition. However, the clinical trial is still essential.
