Abstract
The effects of Mesua ferrea Linn flower (MFE) extract on the pathogenic cascade of Alzheimer's disease (AD) were determined by an in vitro and cell culture model in the search for a potential candidate for the treatment of AD. The 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay exhibited that the MFE extract had antioxidant activities. According to the Ellman and the thioflavin T method's result, the extracts could inhibit acetylcholinesterase and β-amyloid (Aβ) aggregation. Studies on neuroprotection in cell culture found that the MFE extract could reduce the death of human neuroblastoma cells (SH-SY5Y) caused by H2O2 and Aβ. Western blot analysis exhibited that the MFE extract alleviated H2O2-induced neuronal cell damage by downregulating the pro-apoptotic proteins, including cleaved caspase-3, Bax, and by enhancing the expression of anti-apoptotic markers including MCl1, BClxl, and survivin. Moreover, MFE extract inhibited the expression of APP, presenilin 1, and BACE, and increased the expression of neprilysin. In addition, the MFE extract could enhance scopolamine-induced memory deficit in mice. Overall, results showed that the MFE extract had several modes of action related to the AD pathogenesis cascade, including antioxidants, anti-acetylcholinesterase, anti-Aβ aggregation, and neuroprotection against oxidative stress and Aβ. Therefore, the M. ferrea L. flower might be a possibility for further development as a medication for AD.

Abstract
Cancer is one of life's most difficult difficulties and a severe health risk everywhere. Except for haematological malignancies, it is characterized by unchecked cell growth and a lack of cell death, which results in an aberrant tissue mass or tumour. Vascularization promotes tumor growth, which eventually aids metastasis and migration to other parts of the body, ultimately resulting in death. The genetic material of the cells is harmed or mutated by environmental or inherited influences, which results in cancer. Presently, anti-neoplastic medications (chemotherapy, hormone, and biological therapies) are the treatment of choice for metastatic cancers, whilst surgery and radiotherapy are the mainstays for local and non-metastatic tumors. Regrettably, chemotherapy disturbs healthy cells with rapid proliferation, such as those in the gastrointestinal tract and hair follicles, leading to the typical side effects of chemotherapy. Finding new, efficient, targeted therapies based on modifications in the molecular biology of tumor cells is essential because current chemotherapeutic medications are harmful and can cause the development of multidrug resistance. These new targeted therapies, which are gaining popularity as demonstrated by the FDA-approved targeted cancer drugs in recent years, enter molecules directly into tumor cells, diminishing the adverse reactions. A form of cancer treatment known as targeted therapy goes after the proteins that regulate how cancer cells proliferate, divide, and disseminate. Most patients with specific cancers, such as chronic myelogenous leukemia (commonly known as CML), will have a target for a particular medicine, allowing them to be treated with that drug. Nonetheless, the tumor must typically be examined to determine whether it includes drug targets.

Abstract
The present work introduces a simple, electrostatically driven approach to engineered nanomaterial built from the highly cytotoxic [Au2L2]2+ complex (Au2, L = 1,5-bis(p-tolyl)-3,7-bis(pyridine-2-yl)-1,5-diaza-3,7-diphosphacyclooctane (PNNP) ligand) and the pH-sensitive red-emitting [{Re6Q8}(OH)6]4- (Re6-Q, Q = S2- or Se2-) cluster units. The protonation/deprotonation of the Re6-Q unit is a prerequisite for the pH-triggered assembly of Au2 and Re6-Q into Au2Re6-Q colloids, exhibiting disassembly in acidic (pH = 4.5) conditions modeling a lysosomal environment. The counter-ion effect of polyethylenimine causes the release of Re6-Q units from the colloids, while the binding with lysozyme restricts their protonation in acidified conditions. The enhanced luminescence response of Re6-S on the disassembly of Au2Re6-S colloids in the lysosomal environment allows us to determine their high lysosomal localization extent through the colocalization assay, while the low luminescence of Re6-Se units in the same conditions allows us to reveal the rapture of the lysosomal membrane through the use of the Acridine Orange assay. The lysosomal pathway of the colloids, followed by their endo/lysosomal escape, correlates with their cytotoxicity being on the same level as that of Au2 complexes, but the contribution of the apoptotic pathway differentiates the cytotoxic effect of the colloids from that of the Au2 complex arisen from the necrotic processes.

Abstract
Mesenchymal stem cells (MSCs) as undifferentiated cells are specially considered in cell-based cancer therapy due to unique features such as multi-potency, pluripotency, and self-renewal. A multitude of cytokines secreted from MSCs are known to give such multifunctional attributes, but details of their role are yet to be unknown. In the present study, MSCs were cultured, characterized and co-cultured with Molt-4 cells as acute lymphoblastic leukemia cell line in a trans-well plate. Then, cultured Molt-4 alone and Molt-4 co-cultured with MSCs (10:1) were collected on day 7 and subjected to real time-PCR and Western blotting for gene and protein expression assessment, respectively. Ki-67/caspase-3 as well as telomere length were investigated by flow cytometry and real time-PCR, respectively. The results showed that MSCs caused significant decrease in telomere length as well as hTERT gene expression of Molt-4 cells. Also, gene and protein expression of BAD and P53 were significantly increased. Furthermore, the flow cytometry analysis indicated the decrease and increase of the Ki-67 and caspaspase-3 expression, respectively. It was concluded that MSCs co-cultured with Molt-4 cells could be involved in the promotion of Molt-4 cell apoptosis via caspase-3, BAD, and P53 expression. In addition, the decrease of telomere length is another effect of MSCs on Molt-4 leukemic cells.

Abstract
Previous studies both invivo and in vitro have revealed that high levels of fluoride cause neurotoxicity. Mangiferin has been reported to possess antioxidant, antiapoptotic, and anti-inflammatory properties. The present study was designed to characterize the mechanisms by which mangiferin protects against NaF-induced neurotoxicity. Increased levels of proapoptotic Bax, Caspase-3, Caspase-9, and cleaved-caspase 3, as well as a decreased level of antiapoptotic Bcl-2 induced by fluoride in human neuroblastoma SH-SY5Y cells, these effects were prevented by pretreatment of mangiferin. In addition, mangiferin attenuated the enhancement of p-JNK, reductions of Nrf2 and HO-1, and increased level of the mitochondrial fission proteins Drp1 caused by fluoride. Moreover, oxidative stress, as reflected in the levels of reactive oxygen species, 8-hydroxy-2'-deoxyguanosine, and 4-hydroxynonenal, was elevated by fluoride and these effects were again ameliorated by mangiferin. In conclusion, protection by mangiferin against fluoride-induced neurotoxicity involves normalizing the impaired mitochondrial apoptotic pathway and dynamics and reducing oxidative stress via inactivation of the JNK and activation of the Nrf2/HO-1 pathways.

Abstract
Objective To investigate the effect of miRNA210 on primary myocardial cells in lipopolysaccharide(LPS)-induced myocarditis.Methods CCK8 method was used to detect the effect of miRNA210 on the viability of primary myocardial cells in normal or LPS-induced myocarditis rats.ELISA was performed to detect the secretion of tumor necrosis factor(TNF)-α and interleukin(IL)-1β after miRNA210 treatment.Flow cytometry was used to detect the apoptosis of primary myocardial cells before and after the intervention.Western blotting was used to detect the expression of TNF-α and IL-1β.The expression of apoptosis-related proteins bcl-2,bax,caspase-3,and hypoxia inducible factor 1 (HIF1)-vascular endothelial growth factor(VEGF)were detected by Western blotting.Results CCK8 detection results showed that,compared with the control group,the effect of miRNA210 mimic(t=0.000,P=1.000)and siRNA(t=0.686,P=0.500)interference had no significant difference on primary rat cardiomyocytes.The viability of rat primary cardiomyocytes significantly decreased after LPS treatment(t=8.764,P<0.001);compared with LPS group,the viability of rat primary cardiomyocytes significantly increased after inhibition of miRNA210(t=3.576, P=0.012).ELISA showed that,compared with the control group,the expressions of IL-1 β(t=4.166,P=0.014)and TNF-α(t=6.309,P=0.003)were significantly up-regulated after LPS induction;compared with the LPS group,the expressions of IL-1 β(t=4.096,P=0.015)and TNF-α(t=4.424,P=0.011)were significantly increased after application of miRNA210 mimic.After silencing miRNA210,IL-1 β(t=4.287,P=0.012)and TNF-α(t=3.577,P=0.023)were significantly down-regulated.Flow cytometry showed that,compared with the control group,the apoptosis of primary cardiomyocytes induced by LPS was significantly increased(t=32.780,P<0.001);compared with LPS group,the apoptosis induced by LPS was significantly aggravated by miRNA210 mimic(t=7.412,P= 0.002),and the apoptosis rate of primary cardiomyocytes was significantly decreased after miRNA210 was silenced(t=11.720,P<0.001).Western blot analysis showed that,compared with the control group,LPS significantly down-regulated the expression of bcl-2(t=8.346,P=0.001)and increased the expressions of bax(t=12.890,P<0.001)and caspase-3(t=4.331,P=0.012).Compared with LPS group,the expression of bcl-2(t=6.074,P<0.001)was significantly decreased,and the expressions of bax(t=5.376,P=0.022)and caspase-3(t=5.859,P=0.004)were increased after miRNA210 mimic.After silencing miRNA210,the expression of bcl-2 significantly increased(t=3.873,P=0.017),the expressions of bax(t=5.205,P=0.006)and caspase-3(t=2.800,P=0.040)significantly decreased.Compared with the control group,the expressions of HIF1(t =10.380,P=0.001)and VEGF(t=4.973,P=0.008)were significantly up-regulated in LPS group.Compared with LPS group,the expressions of HIF1(t=8.952,P<0.001)and VEGF(t=11.203,P=0.001)were significantly up-regulated after miRNA210 mimic was applied,while HIF1(t=3.893,P=0.017)and VEGF expression(t=3.181,P=0.033)were decreased after miRNA210 was silenced.Compared with LPS group,the expressions of bax(t= 4.899,P=0.008),HIF1(t=2.833,P=0.047),caspase-3(t=2.877,P=0.045),and VEGF(t= 2.994, P=0.040)were significantly decreased,and the expression of bcl-2 was increased(t=3.392,P=0.017).Conclusion Silencing miRNA210 can attenuate LPS-induced cardiomyocyte injury through HIF1-VEGF-mediated apoptotic pathway.

Abstract
Cyclophosphamide (CTX) is a widely used anticancer drug with severe nephrotoxicity. The pentadecapeptide (RVAPEEHPVEGRYLV) from Cyclina sinensis (SCSP) has been shown to affect immunity and to protect the liver. Hence, the purpose of this study was to investigate the ameliorating effect of SCSP on CTX-induced nephrotoxicity in mice. We injected male ICR mice with CTX (80 mg/kg·day) and measured the nephrotoxicity indices, levels of antioxidant enzymes, malondialdehyde (MDA), inflammatory factors, as well as the major proteins of the NF-κB and apoptotic pathways. Cyclophosphamide induced kidney injury; the levels of kidney-injury indicators and cytokines recovered remarkably in mice after receiving SCSP. The activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) increased, while there was a significant decrease in MDA levels. The kidney tissue damage induced by CTX was also repaired to a certain extent. In addition, SCSP significantly inhibited inflammatory factors and apoptosis by regulating the NF-κB and apoptotic pathways. Our study shows that SCSP has the potential to ameliorate CTX-induced nephrotoxicity and may be used as a therapeutic adjuvant to ameliorate CTX-induced nephrotoxicity.

Abstract
Exposure to the food contaminant acrylamide and its reactive epoxide metabolite glycidamide (GA) induces reactive oxygen species (ROS)-mediated oxidative stress and subsequent cellular death. Recent studies have revealed that the toxic effects of acrylamide may be due to GA, especially on male reproductive system cells. In this regard, it is important to determine the effects of GA on Sertoli cells, which are essential cells for the male reproductive system. Antioxidants should be consumed in sufficient quantities to minimise the effects of environmental pollutants. This study aimed to determine the direct toxic effects of GA and protective effects of vitamin C (VitC) against GA-induced damage in Sertoli cells by measuring cell viability, cytotoxicity, lipid peroxidation, ROS, antioxidant enzyme levels, apoptosis and DNA damage. Sertoli cells were exposed to GA for 24 hours at four different concentrations (ranging between 1 and 1000 μM) and in addition to these GA concentrations to VitC (50 μM). The results of cytotoxicity markers, such as cell viability and lactate dehydrogenase (LDH) showed that GA significantly reduced cell viability and increased LDH levels. We also found that GA induced overproduction of intracellular ROS, increased lipid peroxidation in cellular membrane and triggered cell apoptosis and genotoxicity. In addition, VitC supplementation ameliorated the adverse effects of GA on Sertoli cells. Consequently, these findings suggest that GA may damage the cell function in Sertoli cells, depending on the concentration. Additionally, it was evidenced that VitC has an ameliorative effect on toxicity caused by GA.

Abstract
Green nanoparticles represent a revolution in bionanotechnology, providing opportunities to fight life-threatening diseases, such as cancer, with less risk to the environment and to human health. Here, for the first time, we systematically investigated the anticancer activity and possible mechanism of novel silver nanoparticles (N-SNPs) synthesized by Nostoc Bahar M against the MCF-7 breast cancer cells, HCT-116 colorectal adenocarcinoma cells, and HepG2 liver cancer cells, using cell viability assays, morphological characterization with inverted light and transmission electron microscopy, antioxidants and enzymes (glutathione peroxidase (GPx), glutathione (GSH), adenosine triphosphatase (ATPase), and lactate dehydrogenase (LDH)), and western blotting (protein kinase B (Akt), phosphorylated-Akt (p-Akt), mammalian target of rapamycin (mTOR), B-cell lymphoma 2 (Bcl-2), tumor suppressor (p53), and caspase 3). N-SNPs decreased the viability of MCF-7, HCT-116, and HepG2 cells, with half-maximal inhibitory concentrations of 54, 56, and 80 µg/mL, respectively. They also significantly increased LDH leakage, enhanced oxidative stress via effects on antioxidative markers, and caused metabolic stress by significantly decreasing ATPase levels. N-SNPs caused extensive ultrastructural alterations in cell and nuclear structures, as well as in various organelles. Furthermore, N-SNPs triggered apoptosis via the activation of caspase 3 and p53, and suppressed the mTOR signaling pathway via downregulating apoptosis-evading proteins in MCF-7, HCT-116, and HepG2 cells. Ultrastructural analysis, together with biochemical and molecular analyses, revealed that N-SNPs enhanced apoptosis via the induction of oxidative stress and/or through direct interactions with cellular structures in all tested cells. The cytotoxicity of Nostoc-mediated SNPs represents a new strategy for cancer treatment via targeting various cell death pathways. However, the potential of N-SNPs to be usable and biocompatible anticancer drug will depend on their toxicity against normal cells.

Abstract
Enterovirus infection can cause a variety of diseases and severely impair the health of humans, animals, poultry, and other organisms. To resist viral infection, host organisms clear infected cells and viruses via apoptosis. However, throughout their long-term competition with host cells, enteroviruses have evolved a series of mechanisms to regulate the balance of apoptosis in order to replicate and proliferate. In the early stage of infection, enteroviruses mainly inhibit apoptosis by regulating the PI3K/Akt pathway and the autophagy pathway and by impairing cell sensors, thereby delaying viral replication. In the late stage of infection, enteroviruses mainly regulate apoptotic pathways and the host translation process via various viral proteins, ultimately inducing apoptosis. This paper discusses the means by which these two phenomena are balanced in enteroviruses to produce virus-favoring conditions – in a temporal sequence or through competition with each other. This information is important for further elucidation of the relevant mechanisms of acute infection by enteroviruses and other members of the picornavirus family.

Abstract
Photodynamic therapy (PDT) is a cancer treatment modality that utilizes three components: light (λ 650-750 nm), a photosensitizer (PS) and molecular oxygen, which upon activation renders the modality effective. Colorectal cancer has one of the highest incident rates as well as a high mortality rate worldwide. In this study, a zinc (Zn) metal-based phthalocyanine (ZnPcSmix) PS was used to determine its efficacy for the treatment of colon adenocarcinoma cells (DLD-1 and Caco-2). Photoactivation of the PS was achieved by laser irradiation at a wavelength of 680 nm. Dose responses were performed to establish optimal PS concentration and irradiation fluence. A working combination of 20 µM ZnPcSmix and 5 J/cm2 was used. Biochemical responses were determined after 1 or 24 h incubation post-treatment. Since ZnPcSmix is localized in lysosomes and mitochondria, mitochondrial destabilization analysis was performed monitoring mitochondrial membrane potential (MMP). Cytosolic acidification was determined measuring hydrogen peroxide (H2O2) levels in the cytoplasm. Having established apoptotic cell death induction, an apoptosis PCR array was performed to establish the apoptotic mechanism. In DLD-1 cells, expression of genes included 3 up-regulated and 20 down-regulated genes while in Caco-2 cells, there were 16 up-regulated and 22 down-regulated genes. In both cell lines, in up-regulated genes, there was a combination of pro- and anti-apoptotic genes that were significantly expressed. Gene expression results showed that more tumorigenic cells (DLD-1) went through apoptosis; however, they exhibit increased risk of resistance and recurrence, while less tumorigenic Caco-2 cells responded better to PDT, thus being suggestive of a better prognosis post-PDT treatment. In addition, the possible apoptotic mechanisms of cell death were deduced based on the genetic expression profiling of regulatory apoptotic inducing factors.

Abstract
Silver nanoparticles are used in many commercial products in daily life. Exposure to nanosilver has hepatotoxic effects in animals. This study investigated the cytotoxicity associated with polyvinylpyrrolidone-coated nanosilver (23.44 ± 4.92 nm in diameter) exposure in the human hepatoma cell line (HepG2) and normal hepatic cell line (L02), and the molecular mechanisms induced by nanosilver in HepG2 cells. Nanosilver, in doses of 20-160 μg mL-1 for 24 and 48 h, reduced cell viability in a dose- and time-dependent manner and induced cell membrane leakage and mitochondria injury in both cell lines; these effects were more pronounced in HepG2 cells than in L02 cells. Intracellular oxidative stress was documented by reactive oxygen species (ROS) being generated in HepG2 cells but not in L02 cells, an effect possibly due to differential uptake of nanosilver by cancer cells and normal cells. In HepG2 cells, apoptosis was documented by finding that ROS triggered a decrease in mitochondrial membrane potential, an increase in cytochrome c release, activation of caspase 3 and caspase 9, and a decrease in the ratio of Bcl-2/Bax. Furthermore, nanosilver activated the Fas death receptor pathway by downregulation of nuclear factor-κB and activation of caspase 8 and caspase 3. These results suggest that apoptosis induced by nanosilver in HepG2 cells is mediated via a mitochondria-dependent pathway and the Fas death receptor pathway. These findings provide toxicological and mechanistic information that can help in assessing the effects of nanosilver in biological systems, including the potential for anticancer activities.

Abstract
BACKGROUND The lack of selectivity and development of drug-resistance encourage researchers to search for novel, more efficient and multi-targeted agents with less toxicity. OBJECTIVE In this paper, a series of novel chalcone derivatives bearing diverse heterocycles have been synthesized and evaluated for their antiproliferative activity against A549 (Human Lung Adenocarcinoma) and C6 (Rat Brain Glioma) cells. METHOD Structures of the title compounds (3-18) were verified by FT-IR, 1H NMR, 13C NMR, HRMS spectral data and elemental analyses. Antiproliferative activities of the compounds were evaluated using MTT assay, BrdU method, and flow cytometric analysis. RESULTS Compounds 9 and 15 were revealed as the most promising cytotoxic agents due to their selectivity towards A549 cells with lower IC50 values (IC50=0.05 µM and IC50=0.0316 µM) than cisplatin (IC50=0.06 µM). Flow cytometric analysis of compounds 9 and 15 showed that they affected lung cancer cells by the apoptotic pathway. CONCLUSION It is concluded that this study will contribute to the research of novel antiproliferative agents.

Abstract
A series of bromophenol hybrids with N-containing heterocyclic moieties were designed, and their anticancer activities against a panel of five human cancer cell lines (A549, Bel7402, HepG2, HCT116 and Caco2) using MTT assay in vitro were explored. Among them, thirteen compounds (17a, 17b, 18a, 19a, 19b, 20a, 20b, 21a, 21b, 22a, 22b, 23a, and 23b) exhibited significant inhibitory activity against the tested cancer cell lines. The structure-activity relationships (SARs) of bromophenol derivatives were discussed. The promising candidate compound 17a could induce cell cycle arrest at G0/G1 phase and induce apoptosis in A549 cells, as well as caused DNA fragmentations, morphological changes and ROS generation by the mechanism studies. Furthermore, compound 17a suppression of Bcl-2 levels (decrease in the expression of the anti-apoptotic proteins Bcl-2 and down-regulation in the expression levels of Bcl-2) in A549 cells were observed, along with activation caspase-3 and PARP, which indicated that compound 17a induced A549 cells apoptosis in vitro through the ROS-mediated apoptotic pathway. These results might be useful for bromophenol derivatives to be explored and developed as novel anticancer drugs.

Abstract
It has been observed that polymorphonuclear neutrophils (PMN) increase in number and function during obstructive jaundice (OJ). However, the precise mechanisms underlying PMN apoptosis during OJ remain poorly understood. The aim of the present study was to investigate the modulation of cytochrome c (Cytc) on the mitochondrial signaling pathway in bile duct-ligated (BDL) rats and the effect on PMN apoptosis following the intravenous administration of Cytc. Rats were randomly divided into four groups: A control group, a sham group, a BDL group and a BDL + Cytc group (rats with common bile duct ligation as well as Cytc intravenous injection). Blood samples were collected from the inferior vein cava for biochemical analysis and separation of the PMN. PMN apoptosis was evaluated using flow cytometry. The mitochondrial membrane potential (ΔΨm) of PMN was detected by rhodamine-123 staining. The Cytc protein expression levels were examined using western blotting. PMN mitochondria were observed using transmission electron microscopy. The results of the present study revealed that the PMN apoptosis rate in rats decreased gradually from 12 to 72 h following BDL to levels that were significantly lower than those of the control group and the sham group. Compared with the corresponding time point of the BDL group, the BDL + Cytc group showed a significantly increased PMN apoptosis rate. The mean fluorescence intensity (MFI) of ΔΨm decreased from 12 to 72 h following BDL, and was significantly increased compared with the control and sham groups. MFI in the BDL + Cytc group was higher compared with that in the BDL group. Cytc expression levels increased in the mitochondria and decreased in the cytoplasm from the 12 to 72 h in the BDL group, which was significantly different from that in the control and sham groups at the corresponding time points. Compared with the BDL group, Cytc expression levels in the cytoplasm for the BDL + Cytc group tended to gradually and significantly increase. Morphological changes in PMN mitochondria were marginal in BDL rats and marked in the BDL + Cytc group. In the BDL rats, PMN apoptosis was inhibited, a process induced by the mitochondrial apoptotic signaling pathway in which Cytc has an important role. High ΔΨm in the mitochondria and decreased Cytc expression levels in the cytoplasm result in PMN apoptosis inhibition. Intravenous injection of Cytc may help compensate for the lack of Cytc proteins in the cytoplasm, inducing PMN apoptosis following BDL.

Abstract
Defects in apoptosis are common phenomena in many types of cancer and are also a critical step in tumorigenesis. Targeting the apoptotic pathway has been considered an intriguing strategy for cancer therapy. Traditional Chinese medicine (TCM) has been used in the People’s Republic of China for thousands of years, and many of the medicines have been confirmed to be effective in the treatment of a number of tumors. With increasing cancer rates worldwide, the antitumor effects of TCMs have attracted more and more attention globally. Many of the TCMs have been shown to have antitumor activity through multiple targets, and apoptosis pathway-related targets have been extensively studied and defined to be promising. This review focuses on several antitumor TCMs, especially those with clinical efficacy, based on their effects on the apoptotic signaling pathway. The problems with and prospects of development of TCMs as anticancer agents are also presented.

Abstract
BACKGROUND Locoweeds cause significant livestock poisoning and economic loss all over the world. Animals can develop locoism, a chronic neurological disease, after grazing on locoweeds. Oxytropis kansuensis is a variety of locoweed that contains swainsonine as its main toxic ingredient. The purpose of this study was to investigate the apoptotic pathway induced in the cerebrum by swainsonine. RESULTS Twenty-four Sprague-Dawley rats were randomly divided into four groups (experimental groups I, II, III and a control group) and 6 SD rats of each group were feed in 3 cages separately. Rats were penned as groups and fed with feeds containing 15% (SW content 0.03‰), 30% (SW content 0.06‰), or 45% (SW content 0.09‰) O. kansuensis for experimental groups I, II, and III, respectively, or complete feed in the case of the control group. One hundred and nineteen days after poisoning, and all rats showed neurological disorders at different degrees, which were considered to be successful established a chronic poisoning model of O. kansuensis. rats were sacrificed and the expression of Fas, FasL, Bcl-2, Bax as well as cleaved caspase-3, -8 and -9 proteins in brain tissues were detected by Western blot. The results showed that SW treatment up-regulated Fas and Fas ligand (FasL) (P < 0.05), and that there was an increase in Bax and a decrease in Bcl-2 protein (P < 0.01). Moreover, SW treatment significantly increases the activation of caspase-3, 8 and -9, the key effectors in apoptosis pathway (P < 0.01). CONCLUSION Our data suggest that SW induces apoptosis in cells of the brain through death receptor and mitochondria-mediated, caspase-dependent apoptotic pathways in the brain tissue of SD rats.
