AIM: To investigate the effect of gastrodin on the expression of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) in the striatum of cerebral ischemia rats, and to explore the potential mechanism of gastrodin in treating cerebral ischemia. METHODS: The rats were randomly divided into four groups: normal, sham, model, and gastrodin groups, each consisting of 10 rats. After successful modeling using middle cerebral artery occlusion (MCAO), the gastrodin group received intraperitoneal injection of gastrodin injection at a dose of 10 mg/kg once a day for 14 consecutive days. Pathological changes in striatal neurons were observed using Nissl staining. Immunohistochemistry was utilized to detect positive expression of BDNF and IL-6 proteins in the striatum. Additionally, immunoblot analysis was performed to determine the expression levels of BDNF and IL-6 proteins in the striatum. RESULTS: Nissl staining revealed clear and intact structures of striatal neurons in the normal and sham groups, with tightly arranged cells. In the model group, the number of cells was significantly reduced compared to the sham group (P<0.01), and there was a noticeable cytosolic atrophy and loose cell arrangement. The gastrodin group showed a significant increase in the number of Nissl-positive neurons compared to the model group (P<0.01), and there was also a significant improvement in cell morphology. The results of immunohistochemistry and immunoblot were consistent, and there was no statistically significant difference in BDNF and IL-6 protein expression between the normal group and the sham group (P>0.05). Compared to the sham group, the model group showed a decrease in the protein expression level of BDNF in the striatum on the ischemic side (P<0.01) and an increase in the protein expression level of IL-6 (P<0.05, P<0.01). In contrast, the gastrodin group showed an increase in the protein expression level of BDNF in the striatum on the ischemic side (P<0.05, P<0.01) and a decrease in the protein expression level of IL-6 (P< 0.05, P<0.01) compared to the model group. CONCLUSION: Gastrodin has a significant protective effect on striatal injury caused by cerebral ischemia, and its mechanism may be related to the up-regulation of the anti-inflammatory factor BDNF and the down-regulation of the pro-inflammatory factor IL-6.

Objective Mitochondrial reactive oxygen species(mtROS)could cause damage to pancreatic β-cells,rendering them susceptible to oxidative damage.Hence,investigating the potential of the mitochondria-targeted antioxidant(Mito-TEMPO)to protect pancreatic β-cells from ferroptosis by mitigating lipid peroxidation becomes crucial. Methods MIN6 cells were cultured in vitro with 100 μmol/L sodium palmitate(SP)to simulate diabetes.FerroOrange was utilized for the detection of Fe2+fluorescence staining,BODIPY581/591C11 for lipid reactive oxygen species,and MitoSox-Red for mtROS.Alterations in mitophagy levels were assessed through the co-localization of lysosomal and mitochondrial fluorescence.Western blotting was employed to quantify protein levels of Acsl4,GPX4,FSP1,FE,PINK1,Parkin,TOMM20,P62,and LC3.Subsequently,interventions were implemented using Mito-TEMPO and Carbonyl cyanide 3-chlorophenylhydrazone(CCCP)to observe changes in ferroptosis and mitophagy within MIN6 cells. Results We found that SP induced a dose-dependent increase in Fe2+and lipid ROS in MIN6 cells while decreasing the expression levels of GPX4 and FSP1 proteins.Through bioinformatics analysis,it has been uncovered that mitophagy assumes a crucial role within the ferroptosis pathway associated with diabetes.Additionally,SP decreased the expression of mitophagy-related proteins PINK1 and Parkin,leading to mtROS overproduction.Conversely,Mito-TEMPO effectively eliminated mtROS while activating the mitophagy pathways involving PINK1 and Parkin,thereby reducing the occurrence of ferroptosis in MIN6 cells.CCCP also demonstrated efficacy in reducing ferroptosis in MIN6 cells. Conclusion In summary,Mito-TEMPO proved effective in attenuating mtROS production and initiating mitophagy pathways mediated by PINK1 and Parkin in MIN6 cells.Consequently,this decreased iron overload and lipid peroxidation,ultimately safeguarding the cells from ferroptosis.
