| 1 | A novel secretagogin/ATF4 pathway is involved in oxidized LDL-induced endoplasmic reticulum stress and islet β-cell apoptosis显示文摘Excessive accumulation of cholesterol inβcells initiates endoplasmic reticulum(ER)stress and associated apoptosis.We have reported that excessive uptake of cholesterol by MIN6 cells decreases the expression of secretagogin(SCGN)and then attenuates insulin secretion.Here,we aimed to determine whether cholesterol-induced SCGN decrease is involved in the modulation of ER stress and apoptosis in pancreaticβcells.In this study,MIN6 cells were treated with oxidized low-density lipoprotein(ox-LDL)for 24 h,and then intracellular lipid droplets and cell apoptosis were quantified,and SCGN and ER stress markers were identified by western blot analysis.Furthermore,small interfer RNA(siRNA)-mediated SCGN knockdown and recombinant plasmid-mediated SCGN restoration experiments were performed to confirm the role of SCGN in ER stress and associated cell apoptosis.Finally,the interaction of SCGN with ATF4 was computationally predicted and then validated by a co-immunoprecipitation assay.We found that ox-LDL treatment increased the levels of ER stress markers,such as phosphorylated protein kinase-like endoplasmic reticulum kinase,phosphorylated eukaryotic initiation factor 2 alpha,activating transcription factor 4(ATF4),and transcription factor CCAAT-enhancer-binding protein homologous protein,and promoted MIN6 cell apoptosis;in addition,the expression of SCGN was downregulated.siRNA-mediated SCGN knockdown exacerbatedβ-cell ER stress by increasing ATF4 expression.Pretreatment of MIN6 cells with the recombinant SCGN partly antagonized ox-LDL-induced ER stress and apoptosis.Furthermore,a co-immunoprecipitation assay revealed an interaction between SCGN and ATF4 in MIN6 cells.Taken together,these results demonstrated that pancreaticβ-cell apoptosis induced by ox-LDL treatment can be attributed,in part,to an SCGN/ATF4-dependent ER stress response. | Li Wu Yuncheng Lv Ying Lv Sunmin Xiang Zhibo Zhao Ziqing Tang Linling Ou Bin Yan Xinhua Xiao Gebo Wen Renxian Cao Jing Yang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，1： | 2 |

| 3 | Modeling and Simulation of Automatic Berthing based on Bow and Stern Thruster Assist for Unmanned Surface Vehicle显示文摘In order to solve the technical problems of autonomous berthing of the Unmanned Surface Vehicle(USV),this research has met the requirements of maneuverability berthing under different conditions by effectively using the bow and stern thrusters,which is a technological breakthrough in actual production and life.Based on the MMG model,the maneuverability mathematical model of the USV with bow and stern thruster was established.And the motion simulation of USV maneuvering was carried out through the numerical simulation calculation.Then the berthing plan was designed based on the maneuverability analysis of the USV low-speed motion,and the simulation of automatic berthing for USV was carried out.The research results of this paper can be of certain practical significance for the USV based on the support of the bow and stern thruster in the berthing.At the same time,it also provides a certain theoretical reference for the handling of the USV automatic berthing. | Gongxing Wu Xiaolong Zhao Linling Wang | 2021 | Journal of Marine Science2021，3，2： | 0 |
| 4 | Hallmark guided identification and characterization of a novel immune-relevant signature for prognostication of recurrence in stageⅠ-Ⅲlung adenocarcinoma显示文摘The high risk of postoperative mortality in lung adenocarcinoma(LUAD)patients is principally driven by cancer recurrence and low response rates to adjuvant treatment.Here,A combined cohort containing 1,026 stageⅠ-Ⅲpatients was divided into the learning(n Z 678)and validation datasets(n Z 348).The former was used to establish a 16-mRNA risk signature for recurrence prediction with multiple statistical algorithms,which was verified in the valida-tion set.Univariate and multivariate analyses confirmed it as an independent indicator for both recurrence-free survival(RFS)and overall survival(OS).Distinct molecular characteristics between the two groups including genomic alterations,and hallmark pathways were compre-hensively analyzed.Remarkably,the classifier was tightly linked to immune infiltrations,high-lighting the critical role of immune surveillance in prolonging survival for LUAD.Moreover,the classifier was a valuable predictor for therapeutic responses in patients,and the low-risk group was more likely to yield clinical benefits from immunotherapy.A transcription factor regulato-ry proteineprotein interaction network(TF-PPI-network)was constructed via weighted gene co-expression network analysis(WGCNA)concerning the hub genes of the signature.The con-structed multidimensional nomogram dramatically increased the predictive accuracy.There-fore,our signature provides a forceful basis for individualized LUAD management with promising potential implications. | Yongqiang Zhang Zhao Yang Yuqin Tang Chengbin Guo Danni Lin d Linling Cheng Xun Hu Kang Zhang Gen Li | 2023 | Genes & Diseases2023，10，4： | 0 |
| 5 | Effects of Herba Picriae Extract on Growth Performance and Immune Organ Index of Guangxi Partridge Chickens显示文摘[Objectives]The purpose of this experiment was to study the effects of dietary supplementation of Herba Picriae extract on the growth performance and immune organ index of Guangxi partridge chickens.[Methods]A total of 500 one-day-old Guangxi partridge chickens were selected and randomly divided into five groups,five replicates for each group and 20 chickens for each replicate.Groups A,B and C were treatment groups,in which 0.70%,0.35%and 0.175%of Herba Picriae extract was added to the basal diet,respectively.Group D was a positive drug control group,in which 0.01%colistin sulfate premix was supplemented.Group E was a blank control group,in which the chickens were fed the basal diet.The experimental period was 105 d.During the experiment,five chickens were randomly selected from each group on days 21,35 and 49,respectively for the measurement of immune organ index.[Results]When the chickens were fed basal diet supplemented with 0.175%of Herba Picriae extract,their daily body weight gain increased significantly from day 22 to day 35 and from day 71 to day 105 and tended to increase from day 1 to day 21,from day 36 to day 49,and from day 50 to day 70,with a range of 7.37%-8.72%.Dietary supplementation of 0.70%and 0.175%of Herba Picriae extract significantly promoted the growth and development of Fabricius bursae in the experimental chickens.[Conclusions]Dietary supplementation of 0.175%of Herba Picriae extract improved the growth performance and feed intake,as well as 21-d-old bursal index of the experimental chickens. | Cui YANG Xiaoguang LIAO Siqian WU Huofu WAN Jing SHI Huihui CAO Linling ZHAO Dawei LAI Fanquan ZENG Fulin WANG Jiahuang YANG Zhuyue WU | 2020 | Asian Agricultural Research2020，12，4： | 0 |
