Aim To investigate the effects of ginsenoside(GS) on phosphorylation of tau protein,microtubule,cellular apoptosis and its related factors in cellular model of Alzheimer disease(AD) induced by the protein phosphatase 1 and 2A inhibitor okadaic acid(OA).Methods The human neuroblastoma cell line SK-N-SH cells were cultured with GS for 24 h,the culture medium was changed,and then incubated with OA 10 nmol?L-1 for 6 h.The changes of cell morphology were observed by inverted microscope.The laser confocal microscopy was used to observe the microtubule changes.Western blot was applied to determine the expression of phosphorylation of tau protein,and apoptosis-regulating factors Bcl-2,Bax and Caspase-3.The changes of apoptotic cells were observed by TUNEL method.Results The normal SK-N-SH cells spread well.OA-treated cells showed that the cell axons and the microtubules were broken and decreased under the inverted microscope and laser confocal microscope.Preincubation of GS demonstrated the significantly protective effects against the morphologic damage induced by OA.In OA-treated group,the phosphorylation of tau protein at Ser-199/202 and Ser-404 sites was higher than that in normal group,and the non-phosphorylation of tau protein at the same sites was lower;Incubation of GS at the dose of 50 mg?L-1 and 100 mg?L-1 with the cells decreased the phosphorylation of tau protein Ser-199/202 and Ser-404 sites.GS group at the dose of 50 mg?L-1 and 100 mg?L-1 decreased the expression of at non-phosphorylation of tau protein at the Ser202 site.The apoptotic cells were not found in normal group.The number of apoptotic cells were obviously increased.the expression of Bax and caspase-3 significantly enhanced,and Bcl-2 expression decreased in the OA-treated model group.GS significantly decreased the apoptotic cell number of nerve cells,inhibited the expression of Bax and caspase-3.Conclusion GS can protect the nerve cells from pathological change induced by OA.Maybe because it can inhibit the hyperphosphorylation of tau protein and protect the nerve cells from apoptosis,thus GS may have potential to treat Alzheimer disease.

OBJECTIVE:To investigate the effects and the mechanisms of cornel iridoid glycoside(CIG)on antiapoptosis in cellular model of alzheimer disease(AD)induced by the protein phosphatase inhibitor okadaic acid(OA).METHODS:The human neuroblastoma cell line SK-N-SH cells were preincubated with CIG for 24 h,and then incubated with OA 10 nmol for 6 h.The changes of apoptotic cells were observed by TUNEL method.Western blotting was used to determine the expression of apoptosis-regulating factors Bcl-2,Bcl-2 related X protein(Bax)and Caspase-3.RESULTS:The normal SK-N-SH cells spread well and no apoptotic cells appeared.In OA-treated model group,the number of apoptotic cells increased significantly,the expressions of Bax and Caspase-3 increased significantly,but Bcl-2 expression decreased significantly.In CIG(100 and 200 ?g?mL-1)-treated group,the number of apoptotic cells decreased significantly as compared with OA-treated model group,and the expressions of Bax and Caspase-3 decreased significantly whereas Bcl-2 expression increased significantly.CONCLUSION:CIG can inhibit the apoptosis of nerve cells through affecting apoptosis-regulating factors,suggesting its potential as a therapy for AD.

When senescence induction is based on DNA damage, senescent cells display a unique phenotype, which has been termed “senescence-associated secretory phenotype”( SASP ) . SASP, including proinflammatory cytokines, growth factors, chemokines, matrix remodeling enzymes and other cytokines, may be an important driver of chronic inflammation and therefore may be part of a vicious cycle of inflammation, DNA damage and senescence. Senescence-associated secretory products released by such cells can affect the neighboring cells and further exacer-bate their regenerative capacity. SASP is associated with many chronic age-related diseases.

Objective To establish an aging model of mesenchymal stem cells (MSCs) and to investigate aging related biological mechanism for the purpose of studying the senesence of MSCs .Methods MSCs were separated and purified from human placenta, and the cells of the third passage(P3-MSCs) were cultured in the medium for 2 hours, then 100,200 and 300 μmol/L hydrogen peroxide ( H2 O2 ) was added to the cells for 2 hours to establish the MSCs aging model in vitro. Biological characteristics of aging MSCs were evaluated by cell cycle assay and senescence associated β-galactosidase staining.The expression of p16,p21 and p53 genes was further measured using quantitative real-time PCR (RT-PCR).Re-sults Compared with the control , the number of MSCs treated with 200μmol/L H2 O2 for 2 hours was significantly decreased and the cells displayed less adipogenic ,osteogenic and chondrogenic differentiation .Moreover ,after exposure to 200 μmol/L H2 O2 , the majority of the cells were in the G 0/G1 phase as showed by cell cycle analysis .The percentage of senescence-associated β-galactosidase-positive cells was increased , and the expression of p 16 , p21 and p53 mRNA and protein was significantly increased.Conclusion The results of this study has demonstrated that the H 2 O2 (200 μmol/L) can be used to establish the aging model of MSCs in vitro, and the cellular phenotypic alteration may attribute to the cell cycle associated gene expression (p16, p21, and p53).
