The present study was designed to explore phlorotannin eckol protein targets and evaluate the anti-cancer effects of eckol against human breast cancer cells. ProTox-II server and protein-ligand docking analysis deter-mined the aryl hydrocarbon receptor (AhR) as a putative target of eckol. The AhR has been determined as a potential target for breast cancer treatment. The effect of eckol treatment on proliferation, apoptosis, and cell cycle activities was detected in MDA-MB-231 and SK-BR-3 breast cancer cell lines which were selected dependent on AhR expression profiles. Consistent with the AhR expression profile, MDA-MB-231 cells were more sensitive to eckol treatment compared to SK-BR-3 cells in proliferation, apoptosis and cell cycle results. Eckol treatment shows a significant antiproliferative and apoptotic response in breast cancer cells. Overall, these results indicated that the action of eckol may be related to the AhR gene regulation in different breast cancer cell lines.
本研究旨在探索根皮藤素-eckol蛋白靶点,并评价eckol对人乳腺癌症细胞的抗癌作用。ProTox II服务器和蛋白质配体对接分析确定芳烃受体(AhR)是eckol的假定靶标。AhR已被确定为癌症治疗的潜在靶点。在根据AhR表达谱选择的MDA-MB-231和SK-BR-3乳腺癌症细胞系中检测到eckol处理对增殖、凋亡和细胞周期活性的影响。与AhR表达谱一致,与SK-BR-3细胞相比,MDA-MB-231细胞在增殖、凋亡和细胞周期结果方面对eckol处理更敏感。Eckol治疗显示癌症细胞具有显著的抗增殖和凋亡反应。总之,这些结果表明,在不同的乳腺癌症细胞系中,eckol的作用可能与AhR基因调控有关。

This study is designed to investigate the mechanism underlying zoledronic acid for the bone metastasis of breast cancer. Dickkopf 1 (DKK1) was both expressed in breast cancer cells and exosomes isolated from breast cancer cells. The expression of DKK1 was synchronously inhibited in breast cancer cells and exosomes with zoledronic acid or transfecting with cDNA3.1-DKK1. The proliferation and migration of MDA-MB-453 cells were greatly repressed and the differentiation and maturity of osteoclasts were dramatically repressed by exosomes derived from zoledronic acid-treated MDA-MB-453 cells. In the co-cultural system of RAW264.7 cells and MDA-MB-453 cells, the proliferation and migration of MDA-MB-453 cells were facilitated by exosomes derived from MDA-MB-453 cells. Lastly, the EMT progression and TGF-β signaling were significantly blocked by exosomes derived from zoledronic acid-treated MDA-MB-453 cells. Zoledronic acid suppressed the bone metastasis of breast cancer by inhibiting the exosomes loaded with DKK1.
本研究旨在探讨唑来膦酸在乳腺癌骨转移中的作用机制。Dickkopf 1 (DKK1)在乳腺癌细胞和从乳腺癌细胞分离的外泌体中均有表达。用唑来膦酸或转染cDNA3.1-DKK1可同步抑制乳腺癌细胞和外泌体中DKK1的表达。唑来膦酸处理的MDA-MB-453细胞外泌体显著抑制MDA-MB-453细胞的增殖和迁移,显著抑制破骨细胞的分化和成熟。在RAW264.7细胞与MDA-MB-453细胞共培养系统中,MDA-MB-453细胞衍生的外泌体促进了MDA-MB-453细胞的增殖和迁移。最后,来自唑来膦酸处理的MDA-MB-453细胞的外泌体显著阻断EMT进展和TGF-β信号传导。唑来膦酸通过抑制负载DKK1的外泌体抑制乳腺癌骨转移。

This study aims to evaluate the effect of alcoholic extract of Phyllanthus amarus leaves on arsenic-induced histological changes in Wistar rats. Rats were divided into 4 groups: Group I: normal control; Group II: rats received sodium arsenite (40 mg/kg); Group III: rats received sodium arsenite (40 mg/kg) + P. amarus extract (100 mg/kg); Group IV: rats received sodium arsenite (40 mg/kg) + extract (200 mg/kg). All groups were treated by oral gavage with sodium arsenite for 28 days and the animals were subsequently administered (oral) with 100 and 200 mg/kg extract, once daily for two weeks. Animals were sacrificed 24 hours after the last treatment and different organs were collected for histopathological analysis. Results revealed mild to severe type of necrosis and degenerative changes in brain, kidney, and liver of arsenic fed animals. In rats administered with extract showed significant improvements, and the normal histological feature of the cells was almost restored in rats.  These suggest that P. amarus can be used to treat arsenic-induced multi-organ damages.
本研究旨在评价苦叶醇提物对砷诱导的Wistar大鼠组织学变化的影响。将大鼠分为4组:第一组:正常对照组;第二组:大鼠接受亚砷酸钠(40mg/kg);第三组:大鼠接受亚砷酸钠(40mg/kg)+苦杏仁提取物(100mg/kg);第IV组:大鼠接受亚砷酸钠(40mg/kg)+提取物(200mg/kg)。所有组均用亚砷酸钠经口灌胃治疗28天,随后用100和200mg/kg提取物(口服)给药,每天一次,持续两周。最后一次治疗后24小时处死动物,收集不同的器官进行组织病理学分析。结果显示,砷喂养的动物大脑、肾脏和肝脏出现轻度至重度坏死和退行性变化。在给予提取物的大鼠中显示出显著的改善,并且在大鼠中细胞的正常组织学特征几乎恢复。这些结果表明,苦杏仁可用于治疗砷引起的多器官损伤。

Biogenic amines are a group of low molecular weight nitrogenous organic compounds that have an important physiological role in cell proliferation, differentiation, and signal transduction. Also, certain biogenic amines act as an important biomarker for the detection of neuroendocrine and cardiovascular disorders in humans. Besides this, the abundance of biogenic amines in food is recognized as a toxin and anti-nutritional element that have several health implications. This visual experiment demonstrates all the critical steps required for the extraction of biogenic amines followed by derivatization and high performance liquid chromatography analysis for the successive detection and quantification of biogenic amines such as histamine, cadaverine, tryptamine, agmatine, putrescine, 2-phenylethylamine, spermine, tyramine, and spermidine.

This study intends to investigate the effect of thymoquinone against possible ovarian damage and infertility caused by cyclophosphamide in female rats. The rats in the experiment (n=36) were separated into three groups; cyclophosphamide administered, thymoquinone plus cyclophosphamide administered and healthy control. At the end of 30 days of administration, 6 rats from each group were killed and the biochemical and histopathological examina-tions were performed on the ovarian tissues. The remaining animals were kept in the same cage with mature male rats for two months. Infertility developed in 83% of cyclophosphamide group animals. Thymoquinone attenuated cyclophosphamide-related oxidative and inflammatory ovarian damage and reduced the development of infertility. The outcomes suggest that thymoquinone may be useful in treating infertility due to oxidative and inflammatory ovarian damage.
本研究旨在研究胸腺醌对环磷酰胺可能引起的雌性大鼠卵巢损伤和不孕的影响。实验中的大鼠(n=36)被分为三组;环磷酰胺给药、胸腺醌加环磷酰胺给药和健康对照。给药30天后,每组6只大鼠处死,并对卵巢组织进行生化和组织病理学检查。其余动物与成年雄性大鼠一起被关在同一笼子里两个月。83%的环磷酰胺组动物出现不孕。胸腺醌减轻了环磷酰胺相关的氧化和炎症性卵巢损伤,并减少了不孕的发生。研究结果表明,胸腺肽醌可能有助于治疗因氧化和炎症性卵巢损伤引起的不孕不育。

The protective effect of medroxyprogesterone acetate on propionic acid-induced autism in rats was evaluated. For this purpose, 30 rats were divided into three groups. The significant difference in the levels of IL-17 (p<0.05), IL-2 (p<0.05), and TNF-α (p<0.05), lactate (p<0.05), and nerve growth factor (p<0.05) were found in the medroxyprogesterone-treated group by biochemical analysis. In histopathological examination, the medroxyprogesterone-treated group revealed significant improvement in neural body degeneration, neural count, and dysmorphological changes in both CA1 and CA3 regions. Immunohistochemical examination revealed improvement in glial activity with glial fibrillar acidic protein and morphological changes in Purkinje cells. Magnetic resonance spectroscopy showed an improvement in the level of lactate duplets in the medroxyprogesterone-treated group. To our knowledge, this is the first study, to evaluate the protective effect of medroxyprogesterone on propionic acid-induced autism in rats.

Sirtuins (SIRTs) which are nicotinamide adenine dinucleotide (NAD+) dependent class III histondeacetylases have a controversial role in cancer. In this study, the effect of pharmacological inhibition of AK-7, a SIRT2 inhibitor, was investigated in U87 glioblastoma multiforme cells. The cytotoxic effect of AK-7 was evaluated by XTT analysis. After AK-7 treatment, colony forming capacity of cells was determined and apoptosis was evaluated. The expression levels of apoptosis-related genes were determined by qRT-PCR. According to the results, AK-7 inhibited cell proliferation in a dose- and time-dependent manner. After AK-7 treatment, the colony forming capacity of U87 cells was suppressed. And, AK-7 increased apoptosis rate, DNA fragmentation, and caspase-3 activity. According to qRT-PCR, a significant increase was observed in expression levels of apoptosis-related genes. This study revealed that AK-7 inhibits cell proliferation and induces apoptosis in glioblastoma multiforme cells and SIRT2 inhibition can be evaluated as a therapeutic approach in glioblastoma multiforme.
Sirtuins (SIRTs)是烟酰胺腺嘌呤二核苷酸(NAD+)依赖的III类组去乙酰化酶,在癌症中的作用存在争议。本研究研究了SIRT2抑制剂AK-7对U87胶质母细胞瘤多形性细胞的药理抑制作用。采用XTT法评价AK-7的细胞毒作用。AK-7处理后,测定细胞集落形成能力,并观察细胞凋亡情况。采用qRT-PCR检测细胞凋亡相关基因的表达水平。结果表明,AK-7对细胞增殖的抑制作用呈剂量和时间依赖性。AK-7处理后,U87细胞的集落形成能力受到抑制。AK-7增加细胞凋亡率、DNA断裂和caspase-3活性。qRT-PCR结果显示,凋亡相关基因表达水平显著升高。本研究揭示AK-7在多形性胶质母细胞瘤细胞中抑制细胞增殖并诱导细胞凋亡,SIRT2抑制可作为多形性胶质母细胞瘤的一种治疗方法。

The present study aimed to explore the effects of α-cyperone, an extract of Cyperus rotundus, on PC12 cells, as well as the underlying mechanism. Following the cells were induced by oxygen-glucose deprivation/reoxygena-tion (OGD/R), the viability, morphology, inflammation, oxidative stress and apoptotic levels in the cells were evaluated. To explore the mechanism of α-cyperone, cells were treated with 3-TYP, a sirtuin-3 (SIRT3) inhibitor, and then the effects of 3-TYP on the function of α-cyperone were assessed. α-Cyperone was found to reduce OGD/R-induced damage to neuronal viability and alleviate inflammation, oxidative stress, and apoptosis. In addition, α-cyperone could elevate SIRT3 and decline acetyl-forkhead box O1 (FOXO1) levels, and 3-TYP broke the effects of α-cyperone on the aforementioned aspects in the PC12 cells. In conclusion, α-cyperone activated SIRT3 and FOXO1 deacetylation, and alleviated OGD/R-induced cell inflammation, oxidative stress, and apoptosis.
本实验旨在探讨香附提取物α-cyperone对PC12细胞的作用及其机制。氧-糖剥夺/再氧化(OGD/R)诱导细胞后,观察细胞活力、形态学、炎症、氧化应激和凋亡水平。为了探讨α-cyperone的作用机制,我们用sirtuin-3 (SIRT3)抑制剂3-TYP处理细胞,然后评估3-TYP对α-cyperone功能的影响。α-赛柏酮可降低OGD/ r诱导的神经元活力损伤,减轻炎症、氧化应激和细胞凋亡。此外,α-cyperone可以提高SIRT3水平,降低乙酰叉头盒O1 (FOXO1)水平,而3-TYP则打破了α-cyperone在PC12细胞中上述方面的作用。综上所述,α-cyperone可激活SIRT3和FOXO1去乙酰化,减轻OGD/ r诱导的细胞炎症、氧化应激和凋亡。
