1Expression of cyclooxygenase-2 and its pathogenic effects in nonalcoholic fatty liver disease显示文摘Objective:To investigate the expression of cyclooxygenase-2 and its pathological effect in the experimental nonalcoholic fatty liver of rats,and to explore its possible mechanism.Methods:The rat NAFLD model was established by giving a fat-enriched diet.The blood samples were obtained form abdominal aorta and the levels of serum ALT,AST and IL-1,changes in the hepatic tissue 6-k-PGF1α TXB2 were measured.The expression level of COX-2 in rats livers were assayed by immunohistochemistry,RT-PCR and Western-blot.Results:Light microscope analysis revealed that hepatocytes were injured in the model group and slightly in the treatment group.The levels of serum TXB2 and IL-1 in the fatty liver rats were increased.Compared with the model group,the IL-1 and TXB2 increased significantly(P < 0.05),on the contrary,compared with the normal group,the hepatic tissue 6-Keto-prostagland decreased significantly in the model group(P < 0.05),the treatment group also increased but P > 0.05.There was no positive expression of COX-2 in hepatic tissue of normal rats.In the model group,there was positive expression of COX-2 antigen and the number of COX positive cells progressively increased at 4,8,12 wks.The intensity of expression of COX-2 had significantly increased(P < 0.05)and the intensity of COX-2 expression in the treated group decreased remarkably compared with the model group(P < 0.05).The expression of COX-2 mRNA and the level of COX-2 protein were significantly stronger in the liver of model rats compared with normal rats,and significantly weaker in treated rats,than in 8W and 12W model rats(P < 0.05).Conclusion:The increase of COX-2 expression in NAFLD is closely associated with the severity of liver inflammation and damage.COX-2 may play an important role in the progression of rat NAFLD,and the expression of COX-2 mRNA is downregulated by cyclooxygenase-2 inhibitor,which can depress the oxidative stress and control inflammatory response efficiently.Mingbo Cao Lei Dong Xiaolan Lu Jinyan Luo 2008Journal of Nanjing Medical University2008,22,2:7

3Tumor Microenvironment Cascade‑Responsive Nanodrug with Self‑Targeting Activation and ROS Regeneration for Synergistic Oxidation‑Chemotherapy显示文摘Carrier-free nanodrug with exceptionally high drug payload has attracted increasing attentions.Herein,we construct a pH/ROS cascade-responsive nanodrug which could achieve tumor acidity-triggered targeting activation followed by circularly amplified ROS-triggered drug release via positive-feedback loop.The di-selenide-bridged prodrug synthesized from vitamin E succinate and methotrexate(MTX)self-assembles into nanoparticles(VSeM);decorating acidity-cleavable PEG onto VSeM surface temporarily shields the targeting ability of MTX to evade immune clearance and consequently elongate circulation time.Upon reaching tumor sites,acidity-triggered detachment of PEG results in targeting recovery to enhance tumor cell uptake.Afterward,the VSeM could be dissociated in response to intracellular ROS to trigger VES/MTX release;then the released VES could produce extra ROS to accelerate the collapse of VSeM.Finally,the excessive ROS produced from VES could synergize with the released MTX to efficiently suppress tumor growth via orchestrated oxidation-chemotherapy.Our study provides a novel strategy to engineer cascade-responsive nanodrug for synergistic cancer treatment.Yang Li Jinyan Lin Peiyuan Wang Qiang Luo Fukai Zhu Yun Zhang Zhenqing Hou Xiaolong Liu Jingfeng Liu 2020Nano-Micro Letters2020,12,12:2
4Dyskinesia is Closely Associated with Synchronization of Theta Oscillatory Activity Between the Substantia Nigra Pars Reticulata and Motor Cortex in the Off L-dopa State in Rats显示文摘Excessive theta(θ)frequency oscillation and synchronization in the basal ganglia(BG)has been reported in elderly parkinsonian patients and animal models of levodopa(L-dopa)-induced dyskinesia(LID),particularly theθoscillation recorded during periods when L-dopa is withdrawn(the off L-dopa state).To gain insight into processes underlying this activity,we explored the relationship between primary motor cortex(M1)oscillatory activity and BG output in LID.We recorded local field potentials in the substantia nigra pars reticulata(SNr)and M1 of awake,inattentive resting rats before and after L-dopa priming in Sham control,Parkinson disease model,and LID model groups.We found that chronic L-dopa increasedθsynchronization and information flow between the SNr and M1 in off L-dopa state LID rats,with a SNr-to-M1 flow directionality.Compared with the on state,θoscillational activity(θsynchronization and informationflow)during the off state were more closely associated with abnormal involuntary movements.Our findings indicate thatθoscillation in M1 may be consequent to abnormal synchronous discharges in the BG and support the notion that M1θoscillation may participate in the induction of dyskinesia.Jiazhi Chen Qiang Wang Nanxiang Li Shujie Huang Min Li Junbin Cai Yuzheng Wang Huantao Wen Siyuan Lv Ning Wang Jinyan Wang Fei Luo Wangming Zhang 2021Neuroscience Bulletin2021,37,3:1
5Efficient large fragment deletion in plants:double pairs of sgRNAs are better than dual sgRNAs显示文摘Dear Editor,Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)is a powerful and versatile gene editing system that has been extensively utilized in various animals and plants,which holds enormous potential and value for scientific research and breeding.However,single-targeted CRISPR can only induce a few base deletions,insertions,or substitution.Ideally,thesemutations result in premature termination of the protein encoded by the target gene,leading to a loss of function[1].Guoning Zhu Lingling Zhang Liqun Ma Qing Liu Kejian Wang Jinyan Li Guiqin Qu Benzhong Zhu Daqi Fu Yunbo Luo Hongliang Zhu 2023Horticulture Research2023,10,10:1

8Efficient Semi‑Transparent Wide‑Bandgap Perovskite Solar Cells Enabled by Pure‑Chloride 2D‑Perovskite Passivation显示文摘Wide-bandgap(WBG)perovskite solar cells suffer from severe non-radiative recombination and exhibit relatively large opencircuit voltage(V_(OC))deficits,limiting their photovoltaic performance.Here,we address these issues by in-situ forming a well-defined 2D perovskite(PMA)_(2)PbCl_(4)(phenmethylammonium is referred to as PMA)passivation layer on top of the WBG active layer.The 2D layer with highly pure dimensionality and halide components is realized by intentionally tailoring the side-chain substituent at the aryl ring of the post-treatment reagent.First-principle calculation and single-crystal X-ray diffraction results reveal that weak intermolecular interactions between bulky PMA cations and relatively low cation-halide hydrogen bonding strength are crucial in forming the well-defined 2D phase.The(PMA)_(2)PbCl_(4)forms improved type-I energy level alignment with the WBG perovskite,reducing the electron recombination at the perovskite/hole-transport-layer interface.Applying this strategy in fabricating semi-transparent WBG perovskite solar cells(indium tin oxide as the back electrode),the V_(OC)deficits can be reduced to 0.49 V,comparable with the reported state-of-the-art WBG perovskite solar cells using metal electrodes.Consequently,we obtain hysteresis-free 18.60%-efficient WBG perovskite solar cells with a high V_(OC)of 1.23 V.Liu Yang Yongbin Jin Zheng Fang Jinyan Zhang Ziang Nan Lingfang Zheng Huihu Zhuang Qinghua Zeng Kaikai Liu Bingru Deng Huiping Feng Yujie Luo Chengbo Tian Changcai Cui Liqiang Xie Xipeng Xu Zhanhua Wei 2023Nano-Micro Letters2023,15,8:1
9An ischemic area-targeting,peroxynitrite-responsive,biomimetic carbon monoxide nanogenerator for preventing myocardial ischemia-reperfusion injury显示文摘Myocardial ischemia-reperfusion (MI/R) injury is common in patients who undergo revascularization therapy for myocardial infarction, often leading to cardiac dysfunction. Carbon monoxide (CO) has emerged as a therapeutic molecule due to its beneficial properties such as anti-inflammatory, anti-apoptotic, and mitochondrial biogenesis-promoting properties. However, its clinical application is limited due to uncontrolled release, potential toxicity, and poor targeting efficiency. To address these limitations, a peroxynitrite (ONOO )-triggered CO donor (PCOD585) is utilized to generate a poly (lactic-co-glycolic acid) (PLGA)-based, biomimetic CO nanogenerator (M/PCOD@PLGA) that is coated with the macrophage membrane, which could target to the ischemic area and neutralize proinflammatory cytokines. In the ischemic area, local produced ONOO triggers the continuous release of CO from M/PCOD@PLGA, which efficiently ameliorates MI/R injury by clearing harmful ONOO , attenuating the inflammatory response, inhibiting cardiomyocyte apoptosis, and promoting mitochondrial biogenesis. This study provides a novel insight into the safe therapeutic use of CO for MI/R injury by utilizing a novel CO donor combined with biomimetic technology. The M/PCOD@PLGA nanogenerator offers targeted delivery of CO to the ischemic area, minimizing potential toxicity and enhancing therapeutic efficacy.Jinyan Zhang Liwei Liu Zhen Dong Xicun Lu Wenxuan Hong Jin Liu Xiaoyi Zou Jinfeng Gao Hao Jiang Xiaolei Sun Kai Hu Youjun Yang Junbo Ge Xiao Luo Aijun Sun 2023Bioactive Materials2023,,10:1

14IMMUNOHISTOCHEMICAL ANALYSIS OF TGFβ_1 GENE PROTEIN IN SQUAMOUS CELL CARCINOMA OF ESOPHAGUS显示文摘The expression of TGFβ 1 protein in normal esophageal mucosa (EM), esophageal epithelia dysplasia (EED) and squamous cell carcinoma of esophagus (SCCE) were examined immunohistochemically. In order to discover how TGFβ 1 would express in EM, EED and SCCE, wether the rate of TGFβ 1 positive expression might show any correlation with established histologic grade and the presence of lymph node metastasis in SCCE. The results indicate that there isn’t expression in normal cells of EM; The rates of TGFβ 1 positive expression are 62 8% in cells of EED and 77 1% in cells of SCCE, which has statisticaly significant difference compared with EM group. The positive rate of TGFβ 1 increases successively in the order to EM→well EED→moderately EED→poorly EED→SCCE. It suggests that early examination of expression of TGFβ 1 could help predict the occurrence of esophageal cancer. We can’t find any correlation between the positive rate of TGFβ 1 and established histological grade as well as the presence of lymph node metastasis in SCCE.Zhang Jun,Deng Denghao,Luo Jinyan, Wang Kangmin,Zhang Shasha Gastroenterology Section of Internal Medicine, Second Affiliated Hospital, Xi′an Medical University, Xi′an 710004 1999Journal of Pharmaceutical Analysis1999,13,2:0
15Sensitivity Comparison of Immunocapture PCR and Classical PCR for Detection of Burkholderia glumae显示文摘The present study combined the fluoride ion-selective electrode( ISE) method with classical PCR to increase the detection efficiency of Burkholderia glumae. The four antisera of rabbit anti whole cell of B. glumae had been successfully obtained by polyclonal antibody technique,which were ASBg14,ASBg32,ASBg26 and ASBg04,respectively. The titers of four antisera reached 1∶ 32 in ODD test and 1∶ 5 120 in agglutination reaction. All antisera were identified to be qualified antibodies through combined method. The specificity of ASBg14 and ASBg32 was very high,but that of ASBg26 and ASBg04 was not very satisfying. The results showed that all tested strains of B. glumae produced 500 bp specific fragments by direct PCR and immunocapture PCR detection,while others showed negative PCR result. Comparing the sensitivity of these two detection methods,direct PCR could detect about 1 × 10~5 cfu / m L of bacterial suspension while immunocapture PCR could detect as few as 1 × 10~3 cfu / m L,10~2 times higher than direct PCR in sensitivity. In the detecting experiments of artificially inoculated seeds,at least two seeds were required in direct PCR,while only one seed was enough for immunocapture PCR detection.Luo Jinyan Liu Hui Chen Lei Wu Hanbing 2015Plant Diseases and Pests2015,6,3:0
16Enhanced monopole transition strength from the cluster decay of ^(13)C显示文摘The inelastic excitations and cluster decay of ^(13)C have been measured using the reaction,9Be(^(13)C, ^(13)C* →~9Be + α)~9Be. We observe strong excitation to the 14.3-MeV(1/2-) resonant state from the cluster-decay channel, leading to an enhanced monopole matrix element of(6.3 ± 0.6) fm^2. This large cluster-related monopole strength is a clear indication of the cluster-structure domination of this state and is consistent with the recent prediction of the orthogonality condition model(OCM). It would be interesting to further explore the three-center molecular rotational band that is initiated from the observed band-head.Jun Feng YanLin Ye Biao Yang ChengJian Lin HuiMin Jia DanYang Pang ZhiHuan Li JianLing Lou QiTe Li XiaoFei Yang Jing Li HongLiang Zang Qiang Liu Wei Jiang ChenGuang Li Yang Liu ZhiQiang Chen HongYi Wu ChunGuang Wang Wei Liu Xiang Wang JingJing Li DiWen Luo Ying Jiang ShiWei Bai JinYan Xu NanRu Ma LiJie Sun DongXi Wang 2019Science China(Physics,Mechanics & Astronomy)2019,62,1:0
17The H3K9me2-binding protein AGDP3 limits DNA methylation and transcriptional gene silencing in Arabidopsis显示文摘DNA methylation,a conserved epigenetic mark,is critical for tuning temporal and spatial gene expression.The Arabidopsis thaliana DNA glycosylase/lyase REPRESSOR OF SILENCING 1(ROS1)initiates active DNA demethylation and is required to prevent DNA hypermethylation at thousands of genomic loci.However,how ROS1 is recruited to specific loci is not well understood.Here,we report the discovery of Arabidopsis AGENET Domain Containing Protein 3(AGDP3)as a cellular factor that is required to prevent gene silencing and DNA hypermethylation.AGDP3 binds to H3K9me2 marks in its target DNA via its AGD12 cassette.Analysis of the crystal structure of the AGD12 cassette of AGDP3 in complex with an H3K9me2 peptide revealed that dimethylated H3 K9 and unmodified H3 K4 are specifically anchored into two different surface pockets.A histidine residue located in the methyllysine binding aromatic cage provides AGDP3 with pH-dependent H3K9me2 binding capacity.Our results uncover a molecular mechanism for the regulation of DNA demethylation by the gene silencing mark H3K9me2.Xuelin Zhou Mengwei Wei Wenfeng Nie Yue Xi Li Peng Qijie Zheng Kai Tang Viswanathan Satheesh Yuhua Wang Jinyan Luo Xuan Du Rui Liu Zhenlin Yang Honggui La Yingli Zhong Yu Yang Jian-Kang Zhu Jiamu Du Mingguang Lei 2022Journal of Integrative Plant Biology2022,64,12:0
18Recognition of H3K9me1 by maize RNA-directed DNA methylation factor SHH2显示文摘RNA-directed DNA methylation(Rd DM) is a plant-specific de novo DNA methylation pathway,which has extensive cross-talk with histone modifications. Here, we report that the maize RdDM regulator SAWADEE HOMEODOMAIN HOMOLOG 2(SHH2) is an H3 K9 me1 reader. Our structural studies reveal that H3 K9 me1 recognition is achieved by recognition of the methyl group via a classic aromatic cage and hydrogen-bonding and salt-bridge interactions with the free protons of the mono-methyllysine. The di-and tri-methylation states disrupt the polar interactions, decreasing the binding affinity. Our study reveals a monomethyllysine recognition mechanism which potentially links RdDM to H3 K9 me1 in maize.Yuhua Wang Xuelin Zhou Jinyan Luo Suhui Lv Rui Liu Xuan Du Bei Jia Fengtong Yuan Heng Zhang Jiamu Du 2021Journal of Integrative Plant Biology2021,63,6:0
