7Germacrone Induces Apoptosis in Human Hepatoma HepG2 Cells through Inhibition of the JAK2/STAT3 Signalling Pathway显示文摘Previous studies have shown that STAT3 plays a vital role in the genesis and progression of cancer. In this study, we investigated the relationship between the JAK2/STAT3 signalling pathway and germacrone-induced apoptosis in HepG2 cells. HepG2 cells were incubated with germacrone for 24 h, the protein expression of p-STAT3, STAT3, p-JAK2 and JAK2 was detected by Western Blotting, and RT-PCR was used to determine the expression of STAT3, p53, Bcl-2 and Bax at transcriptional levels. Besides that, HepG2 cells were pre-treated with AG490 or IL-6 for 2 h, and then incubated with germacrone for 24 h. The expression of p-JAK2, JAK2, p-STAT3, STAT3, p53, Bax and Bcl-2 was detected by Western blotting. The activity of HepG2 cells was tested by MTT assay. The apoptosis of HepG2 cells and levels of reactive oxygen species (ROS) were flow cytometrically measured. The results showed that germacrone exposure decreased p-STAT3 and p-JAK2 and regulated expression of p53 and Bcl-2 family members at the same time. Moreover, IL-6 enhanced the activation of the JAK2/STAT3 signalling pathway and therefore attenuated the germacrone-induced apoptosis. Suppression of JAK2/STAT3 signalling pathway by AG490, an inhibitor of JAK2, resulted in apoptosis and an increase in ROS in response to germacrone exposure. We therefore conclude that germacrone induces apoptosis through the JAK2/STAT3 signalling pathway.柳昀熠 郑倩 方斌 王维 马凤云 Sadia Roshan Amal Banafa 陈明洁 常俊丽 邓小敏 李克秀 杨广笑 何光源 2013Journal of Huazhong University of Science and Technology(Medical Sciences)2013,33,3:9
8Fucoidan Induces Apoptosis of HepG2 Cells by Down-regulating p-Stat3显示文摘Fucoidan is one of the main bioactive components of polysaccharides. The current study was focused on the anti-tumor effects of fucoidan on human heptoma cell line HepG2 and the possible mechanisms. Fucoidan treatment resulted in cell cycle arrest and apoptosis of HepG2 cells in a dose-dependent manner detected by MTT assay, flow cytometry and fluorescent microscopy. The results of flow cytometric analysis revealed that fucoidan induced G2/M arrest in the cell cycle progression. Hoechst 33258 and Annexin V/PI staining results showed that the apoptotic cell number was increased, which was associated with a dose-dependent up-regulation of Bax and down-regulation of Bcl-2 and p-Stat3. In parallel, the up-regulation of p53 and the increase in reactive oxygen species were also observed, which may play important roles in the inhibition of HepG2 growth by fucoidan. In the meantime,Cyclin B1 and CDK1 were down-regulated by fucoidan treatment. Down-regulation of p-Stat3 by fucoidan resulted in apoptosis and an increase in ROS in response to fucoidan exposure. We therefore concluded that fucoidan induces apoptosis through the down-regulation of p-Stat3. These results suggest that fucoidan may be used as a novel anti-cancer agent for hepatocarcinoma.Sadia Roshan 柳昀熠 Amal Banafa 陈慧洁 李克秀 杨广笑 何光源 陈明洁 2014Journal of Huazhong University of Science and Technology(Medical Sciences)2014,34,3:7
9Preparation and properties of chitosan–metal complex:Some factors influencing the adsorption capacity for dyes in aqueous solution显示文摘Chitosan–metal complexes have been widely studied in wastewater treatment, but there are still various factors in complex preparation which are collectively responsible for improving the adsorption capacity need to be further studied. Thus, this study investigates the factors affecting the adsorption ability of chitosan–metal complex adsorbents, including various kinds of metal centers, different metal salts and crosslinking degree. The results show that the chitosan–Fe( Ⅲ) complex prepared by sulfate salts exhibited the best adsorption efficiency(100%) for various dyes in very short time duration(10 min), and its maximum adsorption capacity achieved 349.22 mg/g. The anion of the metal salt which was used in preparation played an important role to enhance the adsorption ability of chitosan–metal complex. SO_4^(2-) ions not only had the effect of crosslinking through electrostatic interaction with amine group of chitosan polymer, but also could facilitate the chelation of metal ions with chitosan polymer during the synthesis process.Additionally, the p H sensitivity and the sensitivity of ionic environment for chitosan–metal complex were analyzed. We hope that these factors affecting the adsorption of the chitosan–metal complex can help not only in optimizing its use but also in designing new chitosan–metal based complexes.Sadia Rashid Chensi Shen Jing Yang Jianshe Liu Jing Li 2018Journal of Environmental Sciences2018,30,4:6
10Concomitant-chemoradiotherapy-associated oral lesions in patients with oral squamous-cell carcinoma显示文摘Objective:Oral squamous-cell carcinoma(OSCC)accounts for >90% of oral cancers affecting adults mostly between the fourth to seventh decades of life.The most common OSCC treatment is concomitant chemoradiotherapy(CCRT)having both locoregional and distant control,but CCRT has acute and chronic toxic effects on adjacent normal tissue.This study aimed to determine the side effects of CCRT on the oral mucosa and to characterize the clinicopathology of oral lesions in patients with OSCC.Methods:This descriptive,cross-sectional study was certified by the Ethical Review Committee(UHS/Education/126-12/2728)of the University of Health Sciences,Lahore,Pakistan.OSSC patients(n=81)with various histological subtypes,grades,and stages were recruited,and findings on their oral examination were recorded.These patients received 70,90,and 119 Gy of radiotherapy dosages in combination with the chemotherapy drugs cisplatin and 5-fluorouracil.Data were analyzed using SPSS 20.0.Results:The most common presentation of OSCC was a nonhealing ulcer(63%) involving tongue(55.6%).Clinical findings included mucositis(92.6%)and xerostomia of mild,moderate,and severe degrees in 11.1%,46.9%,and 35.8% cases,respectively.Ulcers(87.7%),palpable lymph nodes(64.2%),limited mouth opening(64.2%)and fistula(40.7%) were also observed.In females,the association of radiotherapy dosage with limited mouth opening,xerostomia,and histological grading was statistically significant(P<0.05).The association of chemotherapy drugs with xerostomia(P=0.003)was also statistically significant.Conclusions:CCRT induced mucositis,xerostomia,and trismus in patients with OSCC.Sadia Minhas Muhammad Kashif Wasif Altaf Nadeem Afzal Abdul Hanan Nagi 2017Cancer Biology & Medicine2017,14,2:6
11土壤中重金属形态分布对化学提取的影响显示文摘重金属在土壤中有多种赋存形态,其形态分布不仅决定了土壤污染的程度,也在很大程度上影响着对土壤重金属污染的修复效果。鉴于目前关于重金属的形态分布对化学提取效率影响研究不足的问题,本文以Pb、Cr实际污染的土壤(A1、B1)以及配制的污染土壤(A2、B2)为研究对象,采用改进的BCR连续提取法对土壤重金属的形态进行分析,选取氯化钙、盐酸、氢氧化钠、柠檬酸、乙二胺四乙酸二钠、谷氨酸二乙酸四钠和皂角苷7种化学提取剂对土壤重金属进行提取,对比提取前后重金属的形态分布来确定重金属形态分布对提取效率的影响。结果表明:人工配制污染土壤A2、B2中可提取态重金属的含量(88.07%、79.81%)高于实际污染土壤A1、B1(80.80%、37.55%)。EDTA(乙二胺四乙酸二钠)对A1、A2、B1、B2中重金属的提取效率最高分别为80.09%、89.80%、24.22%、53.63%,7种提取剂振荡提取结果显示,可提取形态重金属含量越高,重金属的提取率越高。对化学提取后重金属的形态进行分析,发现除B1外,EDTA和GLDA(谷氨酸二乙酸四钠)对A1、A2、B2可提取态的去除量占总去除量的比例都达到92%以上,证明了重金属整体的提取率主要是由可提取态重金属的提取率所决定的。臧小龙 谷庆宝 孟柯 Sadia Qayyum 彭昌盛 2017环保科技2017,23,1:6

14Fucoidan Induces G_1 Phase Arrest and Apoptosis through Caspases-dependent Pathway and ROS Induction in Human Breast Cancer MCF-7 Cells显示文摘Fucoidan is an active component of seaweed, which inhibits proliferation and induces apoptosis of several tumor cells while the detailed mechanisms underlying this process are still not clear.In this study, the effect of Fucoidan on the proliferation and apoptosis of human breast cancer MCF-7cells and the molecular mechanism of Fucoidan action were investigated. Viable cell number of MCF-7 cells was decreased by Fucoidan treatment in a dose-dependent manner as measured by MTT assay.Fucoidan treatment resulted in G1 phase arrest of MCF-7 cells as revealed by flow cytometry, which was associated with the decrease in the gene expression of cyclin D1 and CDK-4. Annexin V/PI staining results showed that the number of apoptotic cells was associated with regulation of cytochrome C, caspase-8, Bax and Bcl-2 at transcriptional and translational levels. Both morphologic observation and Hoechst 33258 assay results confirmed the pro-apoptotic effect of Fucoidan. Meanwhile, the ROS production was also increased by Fucoidan treatment, which suggested that Fucoidan induced oxidative damage in MCF-7 cells. The results of present study demonstrated that Fucoidan could induce G1 phase arrest and apoptosis in MCF-7 cells through regulating the cell cycle and apoptosis-related genes or proteins expression, and ROS generation is also involved in these processes.Amal M.

15ω-3多不饱和脂肪酸抗肿瘤新途径——抑制具核梭杆菌黏附宿主细胞显示文摘【背景】大量文献报道ω-3多不饱和脂肪酸尤其是二十二碳六烯酸(Docosahexaenoic Acid,DHA)与二十碳五烯酸(Eicosapentaenoic Acid,EPA)具有抗肿瘤作用,但是其抗肿瘤机制还不够完善。【目的】探究ω-3多不饱和脂肪酸、具核梭杆菌以及结直肠癌三者之间的关联。【方法】在检测二十二碳六烯酸、二十碳五烯酸、α-亚麻酸(α-Linolenic Acid,ALA)等ω-3多不饱和脂肪酸对人结直肠腺癌细胞Caco-2、正常结肠上皮细胞NCM460生长影响的基础上,检测DHA等3种多不饱和脂肪酸对具核梭杆菌黏附人体细胞以及Fap2、FadA、RadD等具核梭杆菌毒力关键基因表达的影响。【结果】30μg/mL的DHA、EPA、ALA对Caco-2生长抑制分别为9.09%、4.95%、7.52%,而对NCM460生长抑制达31.15%、25.48%、29.11%,而且相关抑制作用仅具有浓度依赖性而无时间依赖性。经30μg/mL的DHA、EPA、ALA预处理的具核梭杆菌黏附Caco-2细胞的能力分别下降81.04%(P=0)、93.63%(P=0)和68.63%(P=0);而共培养时加入DHA、EPA、ALA对具核梭杆菌黏附Caco-2细胞的能力没有显著影响。同时,30μg/mLDHA处理导致F.nucleatum的Fap2基因显著下降10.22%(P=0.027);30μg/mL EPA处理导致FadA、Fap2基因分别显著下降23.49%(P=0)、15.09%(P=0.003);30μg/mL ALA处理导致FadA基因显著下降26.75%(P=0.012)。【结论】综合上述实验结果以及DHA、EPA、ALA仅能短时间抑制具核梭杆菌生长等文献报道,我们认为,DHA、EPA等ω-3多不饱和脂肪酸并非简单地直接杀伤或抑制肿瘤细胞和F.nucleatum;抑制FadA、Fap2等黏附相关基因表达,降低F.nucleatum黏附宿主细胞能力是其抗肿瘤作用的关键组成部分。ω-3多不饱和脂肪酸等活性物质对F.nucleatum等在结直肠肿瘤发生、发展中发挥重要作用的肠道细菌的影响与机制应深入开展研究。其力格尔 Sadia Nawab 范殊璇 曹博 李雨昕 田明振 张商浩 马伟 邓子新 2021微生物学通报2021,48,3:4
16Are serum leptin levels predicted by lipoproteins, vitamin D and body composition?显示文摘BACKGROUND Both obesity and vitamin D deficiency are important health issues in Pakistan.The connection between body composition, Vitamin D and leptin in young adults is important to be studied as body composition may affect bone health and therefore the possibility of osteoporosis in later life. Few studies have attempted to investigate the effect of body composition and leptin with vitamin D in adolescence.AIM To investigate the association of serum leptin with body composition, lipids and25-hydroxyvitamin D(25 OHD) in adults.METHODS This cross-sectional study was conducted on 167 apparently healthy adults.Demographics were recorded, bioelectrical impedance analysis was performed and clinical history noted. Serum leptin was measured using DIA source kit on ELISA and total 25 OHD was measured on ADVIA-Centaur; Siemens. Total cholesterol and high density lipoprotein cholesterol were quantified using Enzymatic Endpoint Method and Cholesterol Oxidase-Phenol Aminophenazone method respectively. Biochemical analysis was done in the Departments of Pathology and Laboratory Medicine and Biological and Biomedical Sciences, Aga Khan University Hospital Karachi Pakistan.RESULTS Median age of the group(n = 167) was 20 years(IQR 27-20); 55.7% were females.Majority(89.2%, n = 149) of the study group was 25 OHD deficient, 6%(n = 10)had insufficient serum 25 OHD levels and 4.8%(n = 8) had sufficient D levels.Females, had higher median leptin levels [2.71(IQR 4.76-1.66 ng/mL)] compared to their counterparts [1.3(3.60-0.54 ng/mL), P < 0.01]. Multiple regression analysis suggested that basal metabolic rate, muscle mass, body fat percent, bone mass and serum 25 OHD were the most contributing factors to serum leptin levels. Bone mass and serum 25 OHD in fact bore a negative correlation with leptin.CONCLUSION The results indicate that basal metabolic rate, muscle mass, body fat percent, bone mass and serum 25 OHD have an impact on serum leptin. Being a cross sectional study causal relationship between leptin and other variables could not be determined.Aysha Habib Khan Syeda Sadia Fatima Ahmed Raheem Lena Jafri 2019World Journal of Diabetes2019,10,4:4
17The amazing potential of fungi:50 ways we can exploit fungi industrially显示文摘Fungi are an understudied,biotechnologically valuable group of organisms.Due to the immense range of habitats that fungi inhabit,and the consequent need to compete against a diverse array of other fungi,bacteria,and animals,fungi have developed numerous survival mechanisms.The unique attributes of fungi thus herald great promise for their application in biotechnology and industry.Moreover,fungi can be grown with relative ease,making production at scale viable.The search for fungal biodiversity,and the construction of a living fungi collection,both have incredible economic potential in locating organisms with novel industrial uses that will lead to novel products.This manuscript reviews fifty ways in which fungi can potentially be utilized as biotechnology.We provide notes and examples for each potential exploitation and give examples from our own work and the work of other notable researchers.We also provide a flow chart that can be used to convince funding bodies of the importance of fungi for biotechnological research and as potential products.Fungi have provided the world with penicillin,lovastatin,and other globally significant medicines,and they remain an untapped resource with enormous industrial potential.Kevin D.Hyde Jianchu Xu Sylvie Rapior Rajesh Jeewon Saisamorn Lumyong Allen Grace T.Niego Pranami D.Abeywickrama Janith V.S.Aluthmuhandiram Rashika S.Brahamanage Siraprapa Brooks Amornrat Chaiyasen K.W.Thilini Chethana Putarak Chomnunti Clara Chepkirui Boontiya Chuankid Nimali I.de Silva Mingkwan Doilom Craig Faulds Eleni Gentekaki Venkat Gopalan Pattana Kakumyan Dulanjalee Harishchandra Hridya Hemachandran Sinang Hongsanan Anuruddha Karunarathna Samantha C.Karunarathna Sehroon Khan Jaturong Kumla Ruvishika S.Jayawardena Jian-Kui Liu Ningguo Liu Thatsanee Luangharn Allan Patrick G.Macabeo Diana S.Marasinghe Dan Meeks Peter E.Mortimer Peter Mueller Sadia Nadir Karaba N.Nataraja Sureeporn Nontachaiyapoom Meghan O’Brien Watsana Penkhrue Chayanard Phukhamsakda Uma Shaanker Ramanan Achala R.Rathnayaka Resurreccion B.Sadaba Birthe Sandargo Binu C.Samarakoon Danushka S.Tennakoon Ramamoorthy Siva Wasan Sriprom T.S.Suryanarayanan Kanaporn Sujarit Nakarin Suwannarach Thitipone Suwunwong Benjarong Thongbai Naritsada Thongklang Deping Wei S.Nuwanthika Wijesinghe Jake Winiski Jiye Yan Erandi Yasanthika Marc Stadler 2019Fungal Diversity2019,,4:3
