    本研究旨在研究多柔比星(DOX)和Santolina香豆素精油(SCEO-NANO)纳米制剂的新型组合对肝(HepG2)和结肠(HT29)癌细胞系的细胞毒性作用。
    通过高压均化制备纳米乳液,然后通过zetasizer和傅里叶变换红外光谱进行分析。HepG2和HT29细胞在体外试验中用于凋亡检测。
    配制的液滴尺寸在DOX@SCEO-NANO/DOX中增加到11.54±0.02,分布均匀(PDI=0.13±0.01),当与SCEO-NANO(尺寸:8.91±0.02nm;PDI=0.1±0.02)相比时。在两个细胞中,DOX@SCEO-NANO/DOX导致菌落形成显著减少。与DOX相比,载脂蛋白在HepG2细胞中过表达,显示caspase-3增加8.66倍,Bax/Bcl-2比率增加4.24倍。在HT29细胞中,观察到ROS依赖性坏死和凋亡。比较DOX@SCEO-NANO/DOX与DOX,观察到更高水平的caspase-3和Bax/Bcl-2比率。
    DOX@SCEO-NANO/DOX制剂显示出靶向根除结肠腺癌和肝细胞癌细胞的潜力。
    UNASSIGNED: This study was aimed at investigating the cytotoxic effect of a novel combination of doxorubicin (DOX) and nano-formulation of Santolina chamaecyparissus L. essential oil (SCEO-NANO) on hepatic (HepG2) and colon (HT29) cancer cell lines.
    UNASSIGNED: A nano-emulsion was prepared by high-pressure homogenisation, then analysed by zetasizer and Fourier transform infrared spectroscopy. HepG2 and HT29 cells were used in in vitro tests for apoptosis detection.
    UNASSIGNED: Formulated droplet size increased in DOX@SCEO-NANO/DOX to 11.54 ± 0.02 with uniform distribution (PDI = 0.13 ± 0.01), when compared with SCEO-NANO (size: 8.91 ± 0.02 nm; PDI = 0.1 ± 0.02). In both cells, DOX@SCEO-NANO/DOX led to a considerable reduction in colony formation. Compared to DOX, apoprotein proteins were overexpressed in HepG2 cells, showing increases of 8.66-fold for caspase-3 and 4.24-fold for the Bax/Bcl-2 ratio. In HT29 cells, ROS-dependent necrosis and apoptosis were seen. Comparing DOX@SCEO-NANO/DOX versus DOX, greater levels of caspase-3 and the Bax/Bcl-2 ratio were observed.
    UNASSIGNED: The DOX@SCEO-NANO/DOX formulation showed potential for targeted eradication of colon adenocarcinoma and hepatocellular carcinoma cells.

    急性髓细胞性白血病(AML)的治愈率仍然不理想;因此,这种致命疾病需要新的治疗策略。蒿叶在传统医学中具有重要价值。尽管在全球范围内对这种植物进行了广泛的研究,叶子的特定抗AML特性受到了有限的调查。本研究旨在探讨油蒿乙酸乙酯提取物(EAEAC)的潜在抗白血病活性,使用来自13例AML患者骨髓的单核细胞。为此,使用MTT测定法评估细胞毒性作用,并通过各种方法研究了细胞死亡的机制,包括碘化丙啶染色,膜联蛋白V/碘化丙啶双重染色,线粒体去极化,和caspase-3/7激活测定。结果表明EAEAC通过增加DNA片段化诱导细胞凋亡,导致线粒体去极化,并激活胱天蛋白酶3/7。另一方面,我们评估了EAEAC对两个白血病干细胞亚群的影响,结果表明,他们的频率可能降低(3/5名患者)。
    Cure rates for acute myeloid leukemia (AML) remain suboptimal; thus, new treatment strategies are needed for this deadly disease. Artemisia campestris leaves hold significant value in traditional medicine. Despite extensive research conducted on this plant globally, the specific anti-AML properties of the leaves have received limited investigation. This study aims to explore the potential anti-leukemic activities of the ethyl acetate extract derived from Artemisia campestris (EAEAC), using mononuclear cells from bone marrow of thirteen AML patients. To this end, cytotoxic effects were evaluated using the MTT assay, and the mechanisms of cell death were investigated through various methods, including propidium iodide staining, annexin V/propidium iodide double staining, mitochondrial depolarization, and caspase-3/7 activation assays. Results demonstrated that EAEAC induced cell apoptosis by increasing DNA fragmentation, causing mitochondrial depolarization, and activating caspases 3/7. On the other hand, we assessed EAEAC\'s effect on two leukemia stem cell subpopulations, with results suggesting a potential decrease in their frequencies (three/five patients).

    尽管努力寻找治疗脓毒症相关急性肾损伤(SA-AKI)的有效药物,SA-AKI患者的死亡率没有降低.我们的研究评估了异黄酮奥沙金(OSJ)通过靶向炎症对大鼠SA-AKI的保护作用,氧化应激,和细胞凋亡,这代表了SA-AKI病理生理机制的基石。通过盲肠结扎和穿孔(CLP)技术在大鼠中诱发多微生物败血症。使用生化方法评估肾组织中的氧化应激标志物。白细胞介素-33(IL-33)的表达,8-羟基脱氧鸟苷(8-OHdG),caspase-3和肾损伤分子-1(KIM-1)作为炎症指标,DNA损伤,凋亡,采用免疫组织化学和免疫荧光检测方法分别检测肾组织中的SA-AKI。CLP技术显着(p<0.001)增加了脂质过氧化(LPO)水平,并显着(p<0.001)降低了肾脏组织中超氧化物歧化酶和过氧化氢酶的活性。在肾组织中,IL-33,8-OHdG的强表达,观察到caspase-3和KIM-1在肾小管上皮中严重变性和坏死以及强烈的间质性肾炎。相比之下,OSJ的给药显著(p<0.001)降低了LPO的水平,抗氧化状态的生物标志物明显改善,降低血清肌酐和尿素水平,降低IL-33,8-OHdG的表达,caspase-3和KIM-1减轻了肾脏组织病理学的变化。通过用小鼠IL-33(PDB代码:5VI4)的OSJ结合模式的分子对接研究发现了有希望的结合评分。因此,OSJ通过抑制IL-33/LPO/8-OHdG/caspase-3通路和改善抗氧化系统来保护SA-AKI。
    Despite efforts to find effective drugs for sepsis-associated acute kidney injury (SA-AKI), mortality rates in patients with SA-AKI have not decreased. Our study evaluated the protective effects of isoflavone osajin (OSJ) on SA-AKI in rats by targeting inflammation, oxidative stress, and apoptosis, which represent the cornerstones in the pathophysiological mechanism of SA-AKI. Polymicrobial sepsis was induced in rats via the cecal ligation and puncture (CLP) technique. Markers of oxidative stress were evaluated in kidney tissues using biochemical methods. The expression of interleukin-33 (IL-33), 8-hydroxydeoxyguanosine (8-OHdG), caspase-3, and kidney injury molecule-1 (KIM-1) was evaluated as indicators of inflammation, DNA damage, apoptosis, and SA-AKI respectively in the kidney tissues using immunohistochemical and immunofluorescent detection methods. The CLP technique significantly (p < 0.001) increased lipid peroxidation (LPO) levels and significantly (p < 0.001) decreased the activities of superoxide dismutase and catalase in kidney tissues. In the renal tissues, strong expression of IL-33, 8-OHdG, caspase-3, and KIM-1 was observed with severe degeneration and necrosis in the tubular epithelium and intense interstitial nephritis. In contrast, the administration of OSJ significantly (p < 0.001) reduced the level of LPO, markedly improved biomarkers of antioxidant status, decreased the levels of serum creatinine and urea, lowered the expression of IL-33, 8-OHdG, caspase-3, and KIM-1 and alleviated changes in renal histopathology. A promising binding score was found via a molecular docking investigation of the OSJ-binding mode with mouse IL-33 (PDB Code: 5VI4). Therefore, OSJ protects against SA-AKI by suppressing the IL-33/LPO/8-OHdG/caspase-3 pathway and improving the antioxidant system.

    如今,极低频电磁场(ELF-EMF)被认为是环境污染。数据表明,ELF-EMF可能会影响与表观遗传调控相关的因素,并改变子宫中的重要生物学过程。ELF-EMF对细胞凋亡和氧化应激相关基因的影响尚未在猪子宫内膜中得到证实。这提出了一个问题,即在围植入期暴露于ELF-EMF是否可以诱导猪子宫内膜的细胞凋亡和/或氧化应激。在围植入期收集的猪子宫内膜切片(100±5mg)(n=5),用ELF-EMF以50Hz的频率和8×104mG的通量密度在体外处理2h。为了确定ELF-EMF对子宫内膜细胞凋亡和氧化应激的影响,CASP3,CASP7,CIDEB,GADD45G,使用实时PCR分析NOS1,NOS2,NOS3和TP53I3mRNA转录本,和蛋白质丰度的CASP3,CASP7使用蛋白质印迹,和eNOS使用ELISA进行测定。此外,使用流式细胞术和比色法分析CASP3/7和NOS活性,分别。在ELF-EMF处理的子宫内膜中观察到CASP7降低和NOS3mRNA转录物和蛋白质丰度增加。此外,CIDEB,GADD45G,TP53I3mRNA转录物丰度增加。只有p≤0.05被认为是统计学上显著的差异。记录的改变表明ELF-EMF可能影响子宫内膜中的细胞凋亡并产生氧化应激。对观察到的后果的洞察首次记录了ELF-EMF可能影响子宫内膜细胞增殖的事实,血管生成,和/或在围植入期间的组织接受性。
    Nowadays, the extremely-low-frequency electromagnetic field (ELF-EMF) is recognized as environmental pollution. The data indicate that the ELF-EMF may affect factors related to epigenetic regulation and alter important biological processes in the uterus. The impact of the ELF-EMF on apoptosis and oxidative-stress-related genes has not been documented in porcine endometrium. This raises the question of whether the exposure to the ELF-EMF can induce apoptosis and/or oxidative stress in the endometrium of pigs during the peri-implantation period. Porcine endometrial slices (100 ± 5 mg) collected (n = 5) during the peri-implantation period were treated in vitro with ELF-EMF at a frequency of 50 Hz and flux density of 8 × 104 mG for 2 h. To determine the effect of ELF-EMF on apoptosis and oxidative stress in the endometrium, CASP3, CASP7, CIDEB, GADD45G, NOS1, NOS2, NOS3, and TP53I3 mRNA transcript were analyzed using real-time PCR, and protein abundance of CASP3, CASP7 using Western blot, and eNOS using ELISA were determined. Moreover, CASP3/7 and NOS activity was analyzed using flow cytometry and colorimetry, respectively. The decreased CASP7 and increased NOS3 mRNA transcript and protein abundance in ELF-EMF-treated endometrium were observed. Moreover, CIDEB, GADD45G, and TP53I3 mRNA transcript abundance was increased. Only p ≤ 0.05 was considered a statistically significant difference. The documented alterations indicate the potential of the ELF-EMF to affect apoptosis and generate oxidative stress in the endometrium. The insight into observed consequences documents for the first time the fact that the ELF-EMF may influence endometrial cell proliferation, angiogenesis, and/or tissue receptivity during peri-implantation.

    OBJECTIVE: This study assessed the effect of cevimeline and different concentrations of gum arabic on the parotid gland of rats being given xerostomia-inducing methotrexate.
    METHODS: One hundred twenty-five rats were divided into five equal groups of twenty-five each. The rats in Group I received basic diets, while those in Groups II, III, IV, and V received 20 mg/kg MTX as a single intraperitoneal dose on day one. Group III received 10 mg/kg CVM dissolved in saline orally and daily, and the other two groups received a 10% W/V aqueous suspension of GA. Therefore, Group IV received 2 ml/kg suspension orally and daily, while Group V received 3 ml/kg suspension orally and daily. After 9 days, the parotid glands were dissected carefully and prepared for hematoxylin and eosin (H&E) staining as a routine histological stain and caspase-3 and Ki67 immunohistochemical staining. Quantitative data from α-Caspase-3 staining and Ki67 staining were statistically analysed using one-way ANOVA followed by Tukey\'s multiple comparisons post hoc test.
    RESULTS: Regarding caspase-3 and Ki67 immunohistochemical staining, one-way ANOVA revealed a significant difference among the five groups. For Caspase-3, the highest mean value was for group II (54.21 ± 6.90), and the lowest mean value was for group I (15.75 ± 3.67). The other three groups had mean values of 31.09 ± 5.90, 30.76 ± 5.82, and 20.65 ± 3.47 for groups III, IV, and V, respectively. For Ki67, the highest mean value was for group I (61.70 ± 6.58), and the lowest value was for group II (18.14a ± 5.16). The other three groups had mean values of 34.4 ± 9.27, 48.03 ± 8.40, and 50.63 ± 8.27 for groups III, IV, and V, respectively.
    CONCLUSIONS: GA, rather than the normally used drug CVM, had a desirable effect on the salivary glands of patients with xerostomia.

    本研究旨在探讨男性睾丸实质细胞对化疗药物的敏感性,以及化疗前和化疗后(紫杉醇(PTX))对结构和功能变化的保护作用和机制。为此,将大鼠随机分为四组(对照组=G1,PTX5mg/kg=G2;PTXNoni10mg/kg=G3,PTXNoni20mg/kg=G4)。连续4周腹腔注射PTX,以5mg/kg的剂量给予除对照组外的所有组。然后在10(G3)和20(G4)mg/kg组中口服(灌胃)诺尼14天。生化分析,实时聚合酶链反应(PCR),进行了免疫组织化学分析。根据我们的结果,PTX组大鼠总氧化应激(TOS)和丙二醛(MDA)明显升高(P<0.01)。超氧化物歧化酶(SOD)酶活性和总抗氧化能力(TAC)水平均降低(P<0.01)。用PTX+Noni20mg/kg处理的大鼠的变化是值得注意的。PTXNoni20mg/kg治疗后,PTX的IL1-β(白细胞介素1β)和TNFα(肿瘤坏死因子α)水平降低(P<0.01)(分别为9%和5%)。此外,Noni通过减少caspase-3表达恢复睾丸组织病理学结构,并显着(61%)抑制氧化DNA损伤和凋亡(通过调节Bax(bcl-2样蛋白4)/Bcl-2(B细胞淋巴瘤基因2)比例)。总之,Noni减少了细胞凋亡,并急剧改变了Caspase8和Bax/Bcl-2水平。此外,它大大减少氧化损伤,可用于睾丸变性。
    The current study aimed to investigate the sensitivity of male testis parenchyma cells to chemotherapy agents and the protective effects and mechanisms of Morinda citrifolia (Noni) administration against structural and functional changes before and after chemotherapy (Paclitaxel (PTX)). For this purpose, rats were randomly assigned into four groups (Control = G1, PTX 5 mg/kg = G2; PTX + Noni 10 mg/kg = G3, PTX + Noni 20 mg/kg = G4). PTX was injected intraperitoneally for 4 consecutive weeks, at a dose of 5 mg/kg to all groups except the control group. Then noni was administrated in 10 (G3) and 20 (G4) mg/kg groups orally (gavage) for 14 days. Biochemical analyses, Real-Time Polymerase Chain Reaction (PCR), and immunohistochemical analyses were performed. According to our results, Total Oxidative Stress (TOS) and Malondialdehyde (MDA) were significantly increased in the PTX group (P < 0.01). Superoxide Dismutase (SOD) enzyme activity and Total Antioxidant Capacity (TAC) levels were decreased (P < 0.01). The changes in the rats treated with PTX + Noni 20 mg/kg were noteworthy. The increased levels of IL1-β (Interleukin 1 beta) and TNFα (tumor necrosis factor-alpha) with PTX were down-regulated after treatment with PTX + Noni 20 mg/kg (P < 0.01) (9 % and 5 % respectively). In addition, Noni restored the testicular histopathological structure by reducing caspase-3 expression and significantly (61 %) suppressed oxidative DNA damage and apoptosis (by regulating the Bax (bcl-2-like protein 4)/Bcl-2 (B-cell lymphoma gene-2) ratio). In conclusion, Noni reduced cellular apoptosis and drastically changed Caspase 8 and Bax/Bcl-2 levels. Furthermore, it considerably decreases oxidative damage and can be used in testicular degeneration.

    过敏性结膜炎(AC)是过敏性眼病的最常见形式,也是越来越普遍的疾病。局部滴眼液治疗是治疗AC的常用方法,尽管它们对眼表的影响并不经常被调查。这项研究的目的是进行比较的物理化学表征,新的多剂量不含防腐剂的bilastine0.6%和主要的市售滴眼液的原代结膜和角膜上皮细胞的体外生物学评估。使用MTT测定法测量细胞活力;用ROS敏感探针分析氧化应激;并监测caspase3/7激活评估凋亡。pH值的差异,渗透压,粘度和磷酸盐水平进行鉴定。在所有配方中,比拉斯汀表现出pH,渗透压和粘度值更接近泪膜(7.4,300mOsm/l和~1.5-10mPa·s,分别),是唯一的无磷酸盐溶液。单剂量酮替芬不诱导ROS产生,单剂量氮卓斯汀和比拉斯汀仅引起轻度增加。比拉斯汀和单剂量酮替芬和氮卓斯汀显示出高存活率,这归因于其制剂中不含防腐剂,24小时后不诱导caspase-3/7介导的细胞凋亡。我们的发现支持使用新的bilastine0.6%治疗AC患者,以保持和维持眼表的完整性。
    Allergic conjunctivitis (AC) is the most common form of allergic eye disease and an increasingly prevalent condition. Topical eye drop treatments are the usual approach for managing AC, although their impact on the ocular surface is not frequently investigated. The aim of this study was to perform a comparative physicochemical characterization, and in vitro biological evaluations in primary conjunctival and corneal epithelial cells of the new multidose preservative-free bilastine 0.6% and main commercially available eye drops. MTT assay was used to measure cell viability; oxidative stress was analyzed with a ROS-sensitive probe; and apoptosis was evaluated monitoring caspase 3/7 activation. Differences in pH value, osmolarity, viscosity and phosphate levels were identified. Among all formulations, bilastine exhibited pH, osmolarity and viscosity values closer to tear film (7.4, 300 mOsm/l and ~ 1.5-10 mPa·s, respectively), and was the only phosphates-free solution. Single-dose ketotifen did not induce ROS production, and single-dose azelastine and bilastine only induced a mild increase. Bilastine and single-dose ketotifen and azelastine showed high survival rates attributable to the absence of preservative in its formulation, not inducing caspase-3/7-mediated apoptosis after 24 h. Our findings support the use of the new bilastine 0.6% for treating patients with AC to preserve and maintain the integrity of the ocular surface.

    目的:儿童全身麻醉和镇静药物使用引起了神经毒性的担忧。这种担忧主要基于动物研究,历史麻醉剂,和评估工具,因此需要进一步调查。检测神经元炎症和细胞凋亡的血液生物标志物是检测神经元损伤的新方法。因此,本可行性研究的目的是评估牙科全身麻醉(DGA)中4种血浆生物标志物作为儿童神经毒性替代标志物的有效性.次要目的是比较麻醉暴露前后运动操纵技能的变化。
    方法:这项单中心前瞻性观察性研究包括22名年龄在3至6岁接受DGA的健康儿童。用一组四种血浆生物标志物测量亚临床神经毒性:Caspase-3,神经元特异性烯醇化酶(NSE),神经丝轻链,和S100B在三个时间点(1;在开始时,2;结束和3;从DGA中恢复)。Skillings-Mack检验用于鉴定在三个时间点的生物标志物水平的差异。运动操纵评分评估,在DGA之前和之后两周也进行。
    结果:共纳入22名研究参与者(平均年龄=5±1岁),DGA持续时间中位数为106±28分钟。记录了Caspase-3水平的降低,在三个时间点上进行成对比较,报告时间点2与之间的统计显著性1和时间点3vs.1.尽管记录了NSE水平的波动,两两比较分析后未发现显著变化.在其他生物标志物中,在这3个时期没有显著变化.此外,没有报告操纵性运动评分的显著变化.
    结论:在日间护理DGA期间,Caspase-3在短时间内显着降低;这可能是由于与更广泛的医学相关治疗相比,与牙科治疗相关的麻醉持续时间相对较短。因此,需要进一步研究Caspase-3作为儿科DGA神经毒性的潜在生物标志物,以进一步确定本研究的结果.
    OBJECTIVE: Neurotoxicity concerns have been raised over general anesthesia and sedation medication use in children. Such concerns are largely based on animal studies, historical anesthetic agents, and assessment tools, thus warranting further investigations. Blood biomarkers in detecting neuronal inflammation and apoptosis are novel methods for detecting neuronal damage. Therefore, the aim of this feasibility study was to assess the usefulness of the levels of four plasma biomarkers in dental general anesthesia (DGA) as surrogate markers of neurotoxicity in children. The secondary aim was to compare changes in motor manipulative skills pre- and post-anesthetic exposure.
    METHODS: This single-center prospective observational study included 22 healthy children aged between 3 and 6 years old who underwent DGA. Subclinical neurotoxicity was measured with a panel of four plasma biomarkers: Caspase-3, neuron-specific enolase (NSE), neurofilament light chain, and S100B at three time points (1; at start, 2; end and 3; on recovery from DGA). The Skillings-Mack test was used to identify the difference in the biomarker levels at three time points. Motor manipulative score assessment, prior and two weeks after DGA was also performed.
    RESULTS: A total of 22 study participants (mean age = 5 ± 1 years) were included with a median DGA duration of 106 ± 28 min. A reduction in Caspase-3 levels was recorded, with pairwise comparison over three time points, reporting a statistical significance between time point 2 vs. 1 and time point 3 vs. 1. Although fluctuations in NSE levels were recorded, no significant changes were found following pairwise comparison analysis. Among other biomarkers, no significant changes over the three periods were recorded. Furthermore, no significant changes in manipulative motor scores were reported.
    CONCLUSIONS: Caspase-3 reduced significantly in the short time frames during day-care DGA; this might be due to the relatively short anesthesia duration associated with dental treatment as compared with more extensive medical-related treatments. Therefore, further studies on Caspase-3 as a potential biomarker in pediatric DGA neurotoxicity are required to further ascertain results of this study.

    方法:将80例脾胃虚弱型慢性腹泻患者随机分为两组,分别给予生活方式调整干预和双歧三联活菌胶囊治疗(对照组,n=40)或使用SSWYG(治疗组,n=40)一周,之后评估慢性腹泻的症状。中药系统药理学分析平台(TCMSP),GeneCards,NCBI,利用OMIM数据库和GEO数据库(GSE14841)获得SSWYG和慢性腹泻相关靶标的活性成分和靶蛋白。通过基因本体论(GO)和KEGG分析的拓扑分析获得关键靶标。使用AutoDock软件通过分子对接验证SSWYG对特定靶标的亲和力和结合特性。
    结果:在两组中,胃肠道症状评定量表(GSRS),治疗后Bristol量表及中医证候积分明显改善(P<0.05),治疗组疗效优于对照组(P<0.05)。获得了SSWYG治疗慢性腹泻的68个靶点,通过拓扑分析筛选出33个最可能的。GO和KEGG分析确定了几种慢性腹泻相关途径,包括TNF和IL-17途径。分子对接研究显示SSWYG核心组分对关键靶标CASP3、JNK、IL1B,IL6和AKT1。与SSWYG的多种主要活性成分相比,JUN和CASP3具有最低的结合能和最高的稳定结合能。
    结论:SSWYG可明显改善慢性腹泻的临床症状,可能是通过CASP3和JUN调节TNF和IL-17及其他途径,提示SSWYG的复杂治疗机制涉及多种成分和靶标以及多种途径的协调调节。
    OBJECTIVE: To investigate the efficacy of Jianpiwenyang Gel (SSWYG) for treating chronic diarrhea and explore its therapeutic mechanism.
    METHODS: Eighty patients with chronic diarrhea of spleen and stomach weakness type were randomized into two groups for interventions with lifestyle adjustment and treatment with bifid triple viable capsules (control group, n=40) or naval application with SSWYG (treatment group, n=40) for one week, after which symptoms of chronic diarrhea were evaluated. The Chinese medicine system pharmacology analysis platform (TCMSP), GeneCards, NCBI, OMIM database and GEO database (GSE14841) were used to obtain the active ingredients and target proteins of SSWYG and chronic diarrhea-related targets. The key targets were obtained by topological analysis for Gene Ontology (GO) and KEGG analyses. The affinity and binding characteristics of SSWYG for specific targets were verified by molecular docking using AutoDock software.
    RESULTS: In both groups, gastrointestinal symptom rating scale (GSRS), Bristol Scale and TCM syndrome scores significantly improved after the treatments (P < 0.05), and better effects were observed in the treatment group (P < 0.05). Sixtyeight targets of SSWYG in treating chronic diarrhea were obtained, and 33 most probable ones were screened out by topological analysis. GO and KEGG analyses identified several chronic diarrhea-related pathways including the TNF and IL-17 pathways. Molecular docking study showed good affinity of the core components of SSWYG for the key targets CASP3, JNK, IL1B, IL6, and AKT1. JUN and CASP3 had the lowest binding energy and the highest stable binding energy with multiple major active ingredients of SSWYG.
    CONCLUSIONS: SSWYG can significantly improve clinical symptoms of chronic diarrhea possibly by regulating the TNF and IL-17 as well as other pathways via CASP3 and JUN, suggesting a complex therapeutic mechanism of SSWYG involving multiple ingredients and targets and coordinated regulation of multiple pathways.

    结果:Zea损害了增殖,附着力,U87和U251细胞以及HUVECs的迁移和侵袭。大鼠主动脉环实验显示,在VEGF诱导的微血管萌发过程中,Zea可显着抑制血管生成。体外和体内血管实验证实Zea抑制VEGF诱导的HUVEC增殖和毛细血管样管形成。此外,Zea通过增加切割的PARP和Caspase3的表达来诱导GBM细胞凋亡。在HUVEC和U251GBM细胞中,Zea下调VEGF诱导的VEGFR2激酶途径的活化。同时p-AKT的表达,p-ERK,p-STAT3和FAK在U251细胞中均减弱。此外,VEGFR2激酶抑制剂SU5408可以阻断Zea对GBM细胞增殖的影响。这些结果表明,Zea可能通过下调致癌信号通路的级联来阻碍GBM血管生成和肿瘤生长。两者通过抑制血管生成和抗肿瘤机制的直接细胞毒作用。此外,Zea抑制GBM血管生成和肿瘤生长通过体内异种移植小鼠模型举例说明。
    结论:Zea在体外和体内都会损害GBM的血管生成和肿瘤生长。可以声明Zea是GBM未来治疗策略的潜在有价值的抗癌候选物。
    OBJECTIVE: To investigate the therapeutic effects of Zeaxanthin (Zea), one of the oxidized xanthophyll carotenoids belonging to the isoprenoids, on inhibiting the angiogenesis and tumor growth of glioblastoma (GBM) via an in vitro and in vivo study.
    METHODS: The effects of Zea on the proliferation, adhesion, migration and invasion of human GBM cell lines were detected by cell proliferation assay, cell adhesion assay and Transwell assay. The effect of Zea on angiogenesis was detected by rat aortic ring assay and human umbilical vein endothelial cells (HUVEC) in vitro tube formation assay. The effects of Zea on PARP, Caspase 3 and VEGFR2 phosphorylation as well as VEGFR2\'s downstream signaling pathway were detected by Western blot. The in vivo human GBM xenograft mouse model was employed to study the therapeutic efficacy of Zea.
    RESULTS: Zea impaired the proliferation, adhesion, migration and invasion of U87 and U251 cells as well as HUVECs. Rat aortic ring experiments displayed Zea significantly inhibited angiogenesis during VEGF-induced microvascular germination. In vitro and in vivo vascular experiments verified that Zea inhibited VEGF-induced HUVEC proliferation and capillary-like tube formation. Additionally, Zea induced GBM cells apoptosis via increasing the expression of cleaved PARP and Caspase 3. In HUVECs and U251 GBM cells, Zea down-regulated VEGF-induced activation of the VEGFR2 kinase pathway. Meanwhile the expression of p-AKT, p-ERK, p-STAT3 and FAK were all attenuated in U251 cells. Moreover, the effects of Zea on GBM cells proliferation could be blocked by VEGFR2 kinase inhibitor SU5408. These results suggest that Zea may hinder GBM angiogenesis and tumor growth through down-regulating a cascade of oncogenic signaling pathways, both through the inhibition of angiogenesis and the anti-tumor mechanism of a direct cytotoxic effect. Besides, Zea inhibits GBM angiogenesis and tumor growth exemplified through a xenograft mouse model in vivo.
    CONCLUSIONS: Zea impairs angiogenesis and tumor growth of GBM both in vitro and in vivo. It can be declared that Zea is a potential valuable anticancer candidate for the future treatment strategy of GBM.
