Obejective:To explore the establishment of an oxygen glucose deprivation/reperfusion model of senescent SH-SY5Y cells.Methods:SH-SY5Y cells were randomly divided into control(D-galactose 0 mmol/L group),D-galactose(25 mmol/L,50 mmol/L,100 mmol/L,200 mmol/L,400 mmol/L)groups,and treated with corresponding concentrations of D-galactose for 48 h.The changes of cell morphology,β-galactosidase,the cell morphology,β-galactosidase activity by microscopic observation,cell proliferation rate by EdU kit and cell survival rate by CCK-8 assay were used to determine the decaying concentration of D-galactose and to establish the senescence model.The senescent SH-SY5Y cells were randomly divided into control group(oxygen glucose deprivation without treatment group),oxygen glucose deprivation treatment(0.5 h,1 h,1.5 h,2 h)group,followed by re-glucose reoxygenation for 24 h,and CCK-8 assay for the survival rate of senescent SH-SY5Y cells.Results:There were no significant changes in cell morphology and β-gal activity in the 25 mmol/L and 50 mmol/L groups compared with the control group(P>0.05),cytosolic hypertrophy was seen in the cells of the 100 mmol/L group,chromatin fixation in the cells of the 200 mmol/L group,and massive vacuolization in the cells of the 400 mmol/L group;the positive rate ofβ-galactosidase staining in the cells of the(100-400 mmol/L)group was significantly higher compared with the control group(P<0.05),with little difference between the 100 mmol/L and 200 mmol/L groups(P>0.05);the cell proliferation ability of the(100-400 mmol/L)group was significantly decreased in a concentration-dependent manner(P<0.05);the cell survival rate was decreased in a concentration-dependent manner(P<0.05),with IC_(50) between 100 mmol/L and 200 mmol/L.The survival of senescent SH-SY5Y cells showed a time-dependent decrease in oxygen-glucose deprivation(P<0.05),with an IC_(50) close to 1 h.Conclusion:D-gal concentration of 100 mmoL/L and 48 h of cell action could establish a survival rate of about 50%of senescent SH-SY5Y cells,and oxygen glucose deprivation of senescent SH-SY5Y cells for 1 h and reperfusion for 24 h could establish an oxygen glucose deprivation/reperfusion model of senescent SH-SY5Y cells with a survival rate close to 50%. 展开更多

Objective:To investigate the effect of asiatic acid(AA) on the differentiated human neuroblastoma SH-SY5 Y cells cytotoxic-induced by cholesterol.Methods:Human neuroblastoma SH-SY5 Y cells were either exposed to different concentrations of AA or treated with different doses of cholesterol to reveal their responding viability by MTT assay.The selective 1 mmol/L concentration of AA was then used to test for either the protective or the recovery effects on the cells treated with 250 mmol/L concentration of cholesterol.Results:AA has a propensity to directly increase the viability of differentiated human neuroblastoma SH-SY5 Y cells.Cholesterol has significant cytotoxic effect on those cells in a concentration-dependent manner.AA has the ability to slightly recover the viability of the differentiated culture cytotoxic-induced by cholesterol but could not protect those cells from cytotoxic-induced by cholesterol.Conclusions:High concentrations of cholesterol were observed to be harmful to the neurons and AA had a slight effect of reducing neuronal death caused by cholesterol. 展开更多

Objective:To investigate the neuroprotective effects of Fructus Mume total flavone(FMF)against cell apoptosis and mitochondrial injury induced by 1-methyl-4-phenylpyridinium(MPP^(+))in human neuroblastoma(SH-SY5Y)cells and explore its molecular mechanisms.Methods:MPP^(+) induced SH-SY5Y cells injury model were established in vitro cell culture,the cells were divided into 5 groups:normal control group,model group(250μmol·L^(-1) MPP^(+)),FMF low-and middle-and high-dose experimental group(10,50,100μmol·L^(-1) FMF).After 72 h administration,4’,6-diamidino-2-phenylindole(DAPI)staining was used to observe the effects of different concentrations of FMF on the morphologic changes of apoptotic cells,the ratio of cell apoptosis was measured by Annexin-FITC/PI double staining.The mitochondrial membrane electro-bit were detected by flow cytometry(FCM).The expression of Bcl-2,Bax and Caspase-3 were detected by Western blot.Results:The results of DAPI staining showed that the injury SH-SY5Y cells induced by MPP+were densely condensed,the nucleus showed nuclear shrinkage,showing an apoptotic characteristic morphology;after 72h of FMF action,the apoptotic morphology of the cells showed different degrees of improvement,and the apoptotic number of SH-SY5Y cells also decreased.Compared with that in the normal control group,the apoptotic rate and of mitochondrial membrane electrobit of SH-SY5Y cells in the model group increased significantly(P<0.01),the expression of Bax and Caspase-3 proteins increased significantly(P<0.01),Bcl-2 protein and the ratio of Bcl-2/Bax decreased significantly(P<0.01).Compared with that in the model group,the apoptotic rate and mitochondrial membrane electro-bit of SH-SY5Y cells in FMF groups(10,50,100μmol·L^(-1))were significantly lower,while Bax and Caspase-3 proteins were significantly lower(P<0.01),and Bcl-2 protein and the ratio of Bcl-2/Bax were significantly higher,with statistically significant difference in FMF middle-and high-dose experimental groups(P<0.01).The results indicated that FMF can decrease the experession level of Bax and Caspase-3 and increase the ratio of Bcl-2/Bax,inhibit MPP+induced apoptosis.Conclusion:FMF improves the damage of SH-SY5Y cells induced by MPP+,and plays a neuroprotective effect by regulating the expressions of related proteins in mitochondrial apoptosis pathway. 展开更多

Neonatal hypoxic-ischemic encephalopathy is often associated with permanent cerebral palsy,neurosensory impairments,and cognitive deficits,and there is no effective treatment for complications related to hypoxic-ischemic encephalopathy.The therapeutic potential of human placental chorionic plate-derived mesenchymal stem cells for various diseases has been explored.However,the potential use of human placental chorionic plate-derived mesenchymal stem cells for the treatment of neonatal hypoxic-ischemic encephalopathy has not yet been investigated.In this study,we injected human placental chorionic plate-derived mesenchymal stem cells into the lateral ventricle of a neonatal hypoxic-ischemic encephalopathy rat model and observed significant improvements in both cognitive and motor function.Protein chip analysis showed that interleukin-3 expression was significantly elevated in neonatal hypoxic-ischemic encephalopathy model rats.Following transplantation of human placental chorionic plate-derived mesenchymal stem cells,interleukin-3 expression was downregulated.To further investigate the role of interleukin-3 in neonatal hypoxic-ischemic encephalopathy,we established an in vitro SH-SY5Y cell model of hypoxic-ischemic injury through oxygen-glucose deprivation and silenced interleukin-3 expression using small interfering RNA.We found that the activity and proliferation of SH-SY5Y cells subjected to oxygen-glucose deprivation were further suppressed by interleukin-3 knockdown.Furthermore,interleukin-3 knockout exacerbated neuronal damage and cognitive and motor function impairment in rat models of hypoxic-ischemic encephalopathy.The findings suggest that transplantation of hpcMSCs ameliorated behavioral impairments in a rat model of hypoxic-ischemic encephalopathy,and this effect was mediated by interleukin-3-dependent neurological function. 展开更多

Nucleo CMP Forte? is a nucleotide-based drug consisting of cytidinemonophosphate, uridinemonophosphate, uridin-ediphosphate and uridinetriphosphate. It has been prescribed for peripheral nervous system disorders, such as lum-bosciatalgia, diabetic or alcoholic polyneuropathy, or trigeminal neuralgia. Its effects on brain pathologies has re-ceived little attention. We examined its neuroprotective effects on cell toxicity induced by glutamate excitotoxicity or by 1-methyl-4-phenyl-pyridinium (MPP+), an in vitro cell model of Parkinson’s disease. We used the human dopaminergic cell line SH-SY5Y and a primary culture of rat cortical cells pre-treated with the drug for 24 hours and then exposed to MPP+ or glutamate at a range of concentrations. Cell viability was measured at different times. Nucleo CMP Forte? pre-treatment significantly increased the rate of cell division in SH-SY5Y cells, as well as the synthesis of triglycerides and phospholipids. More interestingly, drug pre-treatment significantly reduced MPP+- and glutamate-induced cell death in SH-SY5Y cells and in rat cortical cells. These results indicate that the nucleotides included in Nucleo CMP Forte? are promising therapeutic molecules for the prevention of neuronal death in brain caused by focal ischemia, Parkinson’s disease or other neurodegenerative pathologies. 展开更多

Nicotinicα4β2 receptor antagonists have drawn increasing attention in the development of new antidepressants.In this study,we aimed to investigate the protective effect of VMY-2-95,the new selective antagonist ofα4β2 nicotinic acetylcholine receptor(nAChR)on corticosterone(CORT)injured mice and cellular models.Fluoxetine was applied as a positive control,and the effects of VMY-2-95 were investigated with three different doses or concentrations(1,3,10 mg/kg in mice,and 0.003,0.03,0.1μmol/L in cells).As a result,VMY-2-95 showed significant antidepressant-like effects in the CORT injured mice by improving neuromorphic function,promoting hippocampal nerve proliferation,and regulating the contents of monoamine transmitters.Meanwhile,VMY-2-95 exhibited protective effects on cell viability,cell oxidant,cell apoptosis,and mitochondrial energy metabolism on corticosterone-impaired SH-SY5 Y cells.Also,the PKA-CREB-BDNF signaling pathway was up-regulated by VMY-2-95 both in vitro and in vivo,and pathway blockers were also combined with VMY-2-95 to verify the effects furtherly.Therefore,we preliminarily proved that VMY-2-95 had protective effects in depressed mice and SH-SY5 Y cells against injuries induced by corticosterone.This work indicated that the application of VMY-2-95 is a potential pharmacological solution for depression.This study also supported the development ofα4β2 nAChR antagonists towards neuropsychiatric dysfunctions. 展开更多

(±)-Crataegusnorin A(la/1b) and B(2a/2b),two pairs of rare 8,9’-epoxy-type norlignan enantiomers featuring a y-butyrolactone ring,were isolated from the fruit of Crataegus pinnatifida.Their structures were determined via extensive spectroscopic analyses.Gauge-independent atomic orbital(GIAO) NMR chemical shift calculations,combined with the advanced statistical method DP4+were employed to establish the relative configurations of four compounds.Next,chiral separation was accomplished by chiral chromatographic column and the absolute configurations of the four compounds were unambiguously assigned by comparison between their experimental electronic circular dichroism curves with the quantum-mechanically calculated curves based on time-dependent density functional theory(TDDFT).All the isolates were evaluated fo r their neuroprotective activities against H2O2-induced cell injury in human neuroblastoma SH-SY5Y cells.The results showed that two pairs of enantiomers 1a/1b and 2a/2b displayed diff;erent effect on neuroprotective activity.Among them,compound 2a displayed the most potent neuroprotective effect Further flow cytometry analysis indicated that 2a could protect SH-SY5Y cells from oxidative damage through inhibiting cell apoptosis. 展开更多
