Abstract
Alzheimer's disease (AD) is a neurodegenerative disease associated with long non-coding RNAs and DNA methylation; however, the mechanisms underlying the role of lncRNA small nucleolar RNA host gene 1 (lncRNA SNHG1) and subsequent involvement of DNA methylation in AD development are not known. The aim of this study was to examine the regulatory mechanisms attributed to lncRNA SNHG1 gene utilizing 2 strains of senescence-accelerated mouse prone 8 (SAMP8) model of AD and compared to senescence-accelerated mouse resistant (SAMR) considered a control. Both strains of the mouse were transfected with either blank virus, psLenti-U6-SNHG1(low gene expression) virus, and psLenti-pA-SNHG1(gene overexpression) virus via a single injection into the brains for 2 weeks. At 2 weeks mice were subjected to a Morris water maze to determine any behavioral effects followed by sacrifice to extract hippocampal tissue for Western blotting to measure protein expression of p-tau, DNMT1, DNMT3A, DNMT3B, TET1, and p-Akt. No marked alterations were noted in any parameters following blank virus transfection. In SAMP8 mice, a significant decrease was noted in protein expression of DNMT1, DNMT3A, DNMT3B, and p-Akt associated with rise in p-tau and TET1. Transfection with ps-Lenti-U6-SNHG1 alone in SAMR1 mice resulted in a significant rise in DNMTs and p-Akt and a fall in p-tau and TET1. Transfection of SAMP8 with ps-Lenti-U6-SNHG1 blocked effects on overexpression noted in this mouse strain. However, knockdown of lncRNA SNHG1 yielded the opposite results as found in SAMR1 mice. In conclusion, the knockdown of lncRNA SNHG1 enhanced DNA methylation through the PI3K/Akt signaling pathway, thereby reducing the phosphorylation levels of tau in SAMP8 AD model mice with ameliorating brain damage attributed to p-tau accumulation with consequent neuroprotection.

Abstract
Schisandra chinensis (S. chinensis) has a long history as a traditional Chinese medicine that is astringent, beneficial to vital energy, tonifies the kidney, tranquilizes the heart, etc. Significantly, Schisandrol A (SA) is extracted from S. chinensis and shows surprising and satisfactory biological activity, including anti-inflammatory, hepatoprotective, cardiovascular protection, and antitumor properties, among others. SA has a more pronounced protective effect on central damaged nerves among its numerous pharmacological effects, improving neurodegenerative diseases such as Alzheimer's and Parkinson's through the protection of damaged nerve cells and the enhancement of anti-oxidant capacity. Pharmacokinetic studies have shown that SA has a pharmacokinetic profile with a rapid absorption, wide distribution, maximal concentration in the liver, and primarily renal excretion. However, hepatic and intestinal first-pass metabolism can affect SA's bioavailability. In addition, the content of SA, as an index component of S. chinensis Pharmacopoeia, should not be less than 0.40%, and the content of SA in S. chinensis compound formula was determined with the help of high-performance liquid chromatography (HPLC), which is a stable and reliable method, and it can lay a foundation for the subsequent quality control. Therefore, this paper systematically reviews the preparation, pharmacological effects, pharmacokinetic properties, and content determination of SA with the goal of updating and deepening the understanding of SA, as well as providing a theoretical basis for the study of SA at a later stage.

Abstract
The aim of this study was to examine the estrogen-like effects of gentiopicroside, macelignan, γ-mangostin, and three lignans (schisandrol A, schisandrol B, and schisandrin C), and their possible mechanism of action. Their effects on the proliferation of the estrogen receptor (ER)-positive breast cancer cell line (MCF-7) were evaluated using Ez-Cytox reagents. The expression of extracellular signal-regulated kinase (ERK), phosphatidylinositol 3-kinase (PI3K), AKT, and estrogen receptor α (ERα) was measured by performing Western blot analysis. 17β-estradiol (E2), also known as estradiol, is an estrogen steroid and was used as a positive control. ICI 182,780 (ICI), an ER antagonist, was used to block the ER function. Our results showed that, except for gentiopicroside, all the compounds promoted proliferation of MCF-7 cells, with schisandrol A being the most effective; this effect was better than that of E2 and was mitigated by ICI. Consistently, the expression of ERK, PI3K, AKT, and ERα increased following treatment with schisandrol A; this effect was slightly better than that of E2 and was mitigated by ICI. Taken together, the ERα induction via the PI3K/AKT and ERK signaling pathways may be a potential mechanism underlying the estrogen-like effects of schisandrol A. This study provides an experimental basis for the application of schisandrol A as a phytoestrogen for the prevention of menopausal symptoms.

Abstract
Schisandrol A possesses pharmacological properties and is used to treat various diseases; however, its effects on osteoarthritis (OA) progression remain unclear. Here, we investigated Schisandrol A as a potential therapeutic agent for OA. In vitro, Schisandrol A effects were confirmed based on the levels of expression of catabolic factors (MMPs, ADAMTS5, and Cox2) induced by IL-1β or Schisandrol A treatment in chondrocytes. In vivo, experimental OA in mice was induced using a destabilized medial meniscus (DMM) surgical model or oral gavage of Schisandrol A in a dose-dependent manner, and demonstrated using histological analysis. In vitro and in vivo analyses demonstrated that Schisandrol A inhibition attenuated osteoarthritic cartilage destruction via the regulation of Mmp3, Mmp13, Adamts5, and Cox2 expression. In the NF-κB signaling pathway, Schisandrol A suppressed the degradation of IκB and the phosphorylation of p65 induced by IL-1β. Overall, and Schisandrol A reduced the expression of catabolic factors by blocking NF-κB signaling and prevented cartilage destruction. Therefore, Schisandrol A attenuated OA progression, and can be used to develop novel OA drug therapies.

Abstract
BACKGROUND Alzheimer's disease (AD) is a common neurodegenerative disease with an increasing incidence rate. Numerous microRNAs (miRNAs) have been found to be involved in AD progression. This study aimed to investigate the expression and diagnostic value of microRNA-331-3p (miR-331-3p) in AD patients and to explore the effects of miR-331-3p on neuronal viability and neuroinflammation. METHODS This study recruited AD patients and used Aβ1-40 treated SH-SY5Y cells mimicking AD characteristics. The expression of miR-331-3p was estimated using reverse transcription quantitative PCR. A receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic value of miR-331-3p, and the correlation of miR-331-3p with patients' Mini-Mental State Examination (MMSE) scores and serum proinflammatory cytokines were analyzed. The effects of miR-331-3p on neuronal viability and inflammatory response were explored in SH-SY5Y cells by in vitro analysis. RESULTS In AD patients and Aβ1-40 treated SH-SY5Y cells, the expression of miR-331-3p was significantly downregulated. Serum miR-331-3p had certain diagnostic potential and was correlated with the MMSE scores and serum proinflammatory cytokine levels of AD patients. In Aβ1-40-treated SH-SY5Y cells, the overexpression of miR-331-3p enhanced cell viability and inhibited inflammatory responses. CONCLUSION The data of this study indicated that serum expression of miR-331-3p is decreased in AD patients, and is correlated with the MMSE scores and proinflammatory cytokine levels of AD patients. In addition, miR-331-3p can regulate the cell viability and the expression of pro-inflammatory cytokines of Aβ1-40 treated SH-SY5Y cells, indicating the potential neuroprotective role of miR-331-3p.

Abstract
Autophagy, a lysosomal degradative pathway, is crucial for the pathogenesis of Alzheimer's disease (AD). Schizandrol A (SchA) shows multiple pharmacological effects. However, the potential effects and mechanisms of SchA on amyloid-β (Aβ)-induced autophagy remain unclear. In this study, differentiated SH-SY5Y cells or primary hippocampal neurons were pretreated with SchA (2 μg/ml) for 1 h before subjected to Aβ1-42 (10 μM) for 24 h to test its effects on cell viability, apoptosis, oxidative stress, and autophagy. Then an mTOR inhibitor (rapamycin) and a PI3K inhibitor (LY294002) were employed to explore the role of PI3K/AKT/mTOR pathway. The results showed that SchA significantly inhibited Aβ1-42-triggered reduction of viable cells, increases of apoptotic cell number and pro-apoptotic protein expressions, as well as alterations of oxidative stress markers. In addition, the increases of LC3-II/LC3-I and Beclin-1 and decrease of p62 were suppressed by SchA. At the molecular level, we found that the inactivation of PI3K/AKT/mTOR pathway was ameliorated by SchA. Inhibition of PI3K/AKT/mTOR pathway deteriorated the protective effects of SchA against Aβ1-42-induced autophagy activation, cell death, and apoptosis. In conclusion, we demonstrate that SchA attenuates Aβ1-42-induced autophagy through activating PI3K/AKT/mTOR signaling pathway. SchA may be a novel drug for the prevention and treatment of AD.

Abstract
Hypoxic preconditioning has been shown to improve hypoxic tolerance in mice, accompanied by the downregulation of DNA methyltransferases (DNMTs) in the brain. However, the roles played by DNMTs in the multiple neuroprotective mechanisms associated with hypoxic preconditioning remain poorly understood. This study aimed to establish an in vitro model of hypoxic preconditioning, using a cultured mouse hippocampal neuronal cell line (HT22 cells), to examine the effects of DNMTs on the endogenous neuroprotective mechanisms that occur during hypoxic preconditioning. HT22 cells were divided into a control group, which received no exposure to hypoxia, a hypoxia group, which was exposed to hypoxia once, and a hypoxic preconditioning group, which was exposed to four cycles of hypoxia. To test the ability of hypoxic preadaptation to induce hypoxic tolerance, cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-5(3-carboxymethonyphenol)-2-(4-sulfophenyl)-2H-tetrazolium assay. Cell viability improved in the hypoxic preconditioning group compared with that in the hypoxia group. The effects of hypoxic preconditioning on the cell cycle and apoptosis in HT22 cells were examined by western blot assay and flow cytometry. Compared with the hypoxia group, the expression levels of caspase-3 and spectrin, which are markers of early apoptosis and S-phase arrest, respectively, noticeably reduced in the hypoxic preconditioning group. Finally, enzyme-linked immunosorbent assay, real-time polymerase chain reaction, and western blot assay were used to investigate the changes in DNMT expression and activity during hypoxic preconditioning. The results showed that compared with the control group, hypoxic preconditioning downregulated the expression levels of DNMT3A and DNMT3B mRNA and protein in HT22 cells and decreased the activities of total DNMTs and DNMT3B. In conclusion, hypoxic preconditioning may exert anti-hypoxic neuroprotective effects, maintaining HT22 cell viability and inhibiting cell apoptosis. These neuroprotective mechanisms may be associated with the inhibition of DNMT3A and DNMT3B.

Abstract
The extract of Schisandrin a traditional Chinese medicine was postulated to be effective in prevention and treatment of Alzheimer's disease (AD). The aim of this study was to examine the underlying protective actions of Schizandrin using a human neuroblastoma cell line (SH-SY5Y). In particular Schizandrin-mediated effects on expression of glycogen synthase kinase (GSK)-3β, protein kinase B (Akt) and Tau protein, known to be altered in AD were determined. In preliminary assays, various concentrations of Schisandrin were incubated SH-SY5Y cells to establish effects on cell viability and potential toxicity in further experimentation. Amyloid-β (Aβ1-42) peptide 10 μmol/L was used to induce in vitro AD model in SH-SY5Y. Exposure to Aβ1-42 significantly reduced cell viability. Treatment with Schisandrin to Aβ1-42 exposed cells increased cell viability compared to amyloid peptide; however only the 10 μmol/L Schisandrin concentration was effective in restoring cell viability to control. Western blot analysis demonstrated that Aβ1-42 produced a significant decrease in p-Akt protein expression levels accompanied by marked elevation in p-tau and p-GSK-3β protein expression levels. Addition of 10 μmol/L Schisandrin to amyloid-treated SH-SY5Y cells was found to significantly increase protein expression levels of p-Akt associated with reduction in expression levels of p-tau and p-GSK-3β protein. Treatment with 10 μmol/L Schisandrin of SH-SY5Y cells with the p-Akt inhibitor LY294002 demonstrated that the herbal-induced rise in p-Akt protein expression was diminished by this inhibitor indicating that signal transduction occurred in the observed cellular effects. Evidence indicates that Schisandrin inhibition of Aβ1-42 -mediated cellular damage in AD neurons may involve activation of the PI3K/Akt signaling pathway where up-regulation of p-Akt activity consequently leads downstream to decreased activity of p-GSK-3β phosphorylation accompanied by reduced tau protein. Consequently, restoration of neuronal cell viability was noted. Our findings suggest that the use of Schisandrin may be considered beneficial as a therapeutic agent in AD.

Abstract
A number of complex human diseases including neurological diseases is characterized by dysregulation of long-chain noncoding RNA (lncRNA). The pathogenesis of Alzheimer's disease (AD), a neurodegenerative disorder is believed to involve alterations in lncRNAs. However, the specific lncRNAs modified in AD remain to be determined. The aim of this study was to identify lncRNAs associated with AD using human neuroblastoma cell line (SH-SY5Y) treated with beta-amyloid (Aβ) as a model of this disease. The differential expressions of lncRNA were compared between beta-amyloid (Aβ) SH-SY5Y cells and normal SH-SY5Y cells utilizing Illumina X10 gene sequencing. The differential expression profiles of amyloid (Aβ)-treated SH-SY5Y cells were determined and verified by qRT-PCR method. The expression levels of lncRNA were expressed by calculating the abundance of FPKM (measure gene expression). The differential expression of log2 (multiple change) >1 or log2 (multiple change) < -1 had statistical significance (P< .05). The differential expression profiles of amyloid (Aβ)-treated SH-SY5Y cells showed 40 lncRNA were up-regulated, while 60 lncRNA were down-regulated. GO and KEGG analysis demonstrated that differentially expressed genes were predominantly involved in the mitogen-activated protein kinase (MAPK) signaling pathway, p53 signaling pathway, hepatitis B, cell cycle, post-translational protein modification, and regulation. In conclusion, approximately 100 dysregulated lncRNA transcripts were found in amyloid (Aβ)-treated SH-SY5Y cells and these lncRNAs may play an important role in the occurrence and development of AD through altered signal pathways.

Abstract
It is well-known that hypoxia induces neuronal injury; however, the mechanisms underlying this observed effect remain to be determined. Schisandra chinensis lignans (SCL). The aim of this study was thus to examine the ability of Schisandra chinensis lignans (SCL) to prevent hypoxia-induced neuronal injury using a human adrenal pheochromocytoma cell line (PC12). Exposure to hypoxia significantly reduced cell survival rate in cultured PC12 cells. However, pretreatment with SCL at 10, 20 or 40 μmol/L followed by hypoxia prevented loss of cellular viability. Flow cytometry demonstrated that the apoptotic rate in PC12 cells following hypoxia was significantly increased. Pretreatment with SCL 20 or 40 μmol/L in hypoxia-exposed cells resulted in significantly reduced apoptotic rates compared to hypoxia. Immunocytochemical staining showed that protein expression of p-Akt was significantly diminished by hypoxia. Following pre-treatment with different concentrations of SCL, PC12 cells were markedly stimulated as evidenced by elevated protein expression of p-Akt in a concentration-dependent manner. The expression of p-Akt protein in the presence of PI3K/Akt signaling pathway inhibitor LY294002 and SCL was not markedly changed indicating that signal transduction was affected by this Chinese herb. There were no significant differences in total Akt protein expression following hypoxia or pretreatment with SCL. Western blot demonstrated that expression levels of caspase-3 protein were significantly increased while expression levels of Bcl-2 protein were decreased in hypoxic cells. Pretreatment with SCL followed by hypoxia significantly lowered expression levels of caspase-3 protein accompanied by elevated expression levels of Bcl-2 protein in a concentration-dependent manner. After co-incubation with LY29004 and SCL, down-regulation of expression of caspase-3 protein and up-regulation of the expression of Bcl-2 protein noted with SCL alone were suppressed. Data suggest that the protective effect exerted by SCL in hypoxia-induced PC12 cell injury involves enhanced cell proliferation and inhibition of apoptosis mediated by activation of PI3K/Akt signaling pathway. The increased protein Akt phosphorylation expression levels resulted in consequent reduced downstream caspase-3 expression and enhanced Bcl-2 expression.

Abstract
Schisandrin B, an active substance, is derived from Chinese herb fruit Wuweizi, which exerts various pharmacological activities and has displayed significant beneficial effects in ameliorating Alzheimer's disease (AD). The aim of this study was to further extend our examination for the use of schisandrin B extract in the potential treatment of AD effects by investigating DNA methylation (DNMT), known to be modified in this disease using SH-SY5Y neuronal cell line exposed to β-amyloid protein (Aβ1-42). In particular, the purpose of this investigation was to examine alterations in mRNA and protein expression of DNMT. Data demonstrated that schisandrin B blocked Aβ1-42-mediated injury in SH-SY5Y neuronal cell line as evidenced by a restoration of cellular morphology and cell viability to approximate control levels at the highest 10 μg/ml Schisandrin B. Incubation with Aβ1-42 significantly decreased mRNA and protein expression of DNMT3A and DNMT1 in SH-SY5Y neuronal cell line. Incubation with Aβ1-42 followed by 24 treatment with schisandrin B significantly inhibited the Aβ1-42 -induced changes in mRNA and protein expression of DNMT3A and DNMT3B in a concentration-dependent manner. It is of interest that the mRNA expression of DNMT3A and DNMT1 were significantly higher than control. Data thus indicate schisandrin B was effective in inhibiting the actions of Aβ1-42 on cell survival and morphology and that DNA methylation may be associated with the beneficial findings.

Abstract
Epigenetic processes such as DNA methylation are essential for processes of gene expression in normal mammalian development. DNA methyltransferases (DNMT) are responsible for initiating and maintaining DNA methylation. It is known that 5-Aza-CdR, an inhibitor of DNMT induces cytotoxicity by reducing DNMT activity in various tumor cell lines. However, disturbances in neuronal DNA methylation may also play a role in altered brain functions. Thus, it was of interest to determine whether alterations in DNA methylation might be associated with neuronal functions by using 5-Aza-CdR, on mouse hippocampus-derived neuronal HT22 cell line. In particular, the aim of this study was to investigate the effects of 5-Aza-CdR on cell growth inhibition, cell cycle arrest, apoptosis as well as the expression levels of DNMT in HT22 cells. HT22 cells were incubated with 5 or 20 μmol/L 5-Aza-CdR for 24 h. Data showed that 5-Aza-CdR at both concentrations significantly inhibited proliferation of HT22 cells and exacerbated cytoplasmic vacuolization. Flow cytometry analysis demonstrated that 5-Aza-CdR treatment at both concentrations decreased early apoptosis but enhanced late apoptosis. Cell cycle analysis illustrated that 5-Aza-CdR treatment induced S phase arrest. Further, incubation with 5-Aza-CdR produced a down-regulation in expression of mRNA and protein DNMT1 and 3A but no marked changes were noted in DNMT 3B and p21 expression. In addition, DNMT1 activity was significantly decreased at both 5-Aza-CdR concentrations. Evidence indicates that 5-Aza-CdR induced cytotoxicity was associated with altered mRNA and protein expression of DNMT 1 and 3A associated with reduced DNMT1 activity in HT22 cells which might affect brain functions.

Abstract
Vanadate is a transition element that present in nature and was shown to be a nonspecific inhibitor of protein tyrosine phosphatases. It was reported that vanadium (Vd) compounds exhibit antitumor actions in several cancer cell lines. This study aimed to examine the antiproliferative and apoptotic actions of different concentrations of sodium vanadate (NaVd) (+5) in esophageal squamous carcinoma cell line EC109 by determining the protein expression levels of cyclin D1 and caspase-3 following incubation for various times from 15 min up to 4 h. In addition, cell proliferation of EC109 treated with different concentrations (NaVd) was also measured using the MTT assay at 4, 12, 24, and 48 h. The cell cycle of EC109 cells exposed to different concentrations of NaVd was detected using flow cytometry determination at 24 h. Data showed that NaVd greater than 100 µM significantly increased cyclin D1. In contrast, reduced caspase-3 protein expression levels occurred at 50 µM. Cellular proliferation was significantly decreased at 50uM. The cell cycle was arrested at S phase with 100 µM NaVd. Taken together, data indicate that NaVd produced concentration- and time-dependent antitumor actions in EC109 cell line.
