| 1 | Dysfunction of PLA2G6 and CYP2C44-associated network signals imminent carcinogenesis from chronic inflammation to hepatocellular carcinoma显示文摘很少长期的发炎怎么贡献 hepatocellular 癌(HCC ) 的前进被知道,特别癌症的开始。揭开从长期的发炎的批评转变到在网络水平的 HCC 和分子的机制,我们用我们的动态网络 biomarker (DNB ) 分析了土拨鼠肝炎 virus/c-myc 鼠标和匹配年龄的 wt-C57BL/6 鼠标的时间系列 proteomic 数据模型。DNB 分析显示在转基因的老鼠的出生以后的第 5 月是癌症开始的批评时期,就在批评转变前,它与临床的症状一致。同时,联系 DNB 的网络在批评转变前后显示出蛋白质表示和 coexpression 层次的激烈的倒置。DNB, PLA2G6 和 CYP2C44 的二个成员,与他们的联系差别一起表示了蛋白质,被发现导致 arachidonic 酸新陈代谢的机能障碍,进一步通过短暂受体潜力隧道的煽动性的调停人规定激活煽动性的回答,并且最后导致肝 detoxification 和恶意的转变的缺陷到癌症。作为一个 c-Myc 目标, PLA2G6 断然在表示与 c-Myc 相关,显示出从减少到在 carcinogenesis 期间增加的一个趋势,与在批评转变的最小的点或付小费给的点。相应 PLA2G6 和 c-Myc 的如此的趋势也在人的 hepatocarcinogenesis 期间被观察,与在高级 dysplastic 小瘤(就在 carcinogenesis 前的一个阶段) 的最小的点。我们的学习暗示 PLA2G6 可能在 hepatocarcinogenesis 期间作为象著名 c-Myc 一样的 oncogene 工作,当 PLA2G6 和 c-Myc 的 downregulation 能是显示逼近的 carcinogenesis 的一个警告信号时。 | Meiyi Li Chen Li Wei-Xin Liu Conghui Liu Jingru Cui Qingrun Li Hong Ni Yingcheng Yang Chaochao Wu Chunlei Chen Xing Zhen Tao Zeng Mujun zhao Lei Chen Jiarui Wu Rong Zeng Luonan Chen | 2017 | Journal of Molecular Cell Biology2017,9,6: | 12 |
| 2 | Edge biomarkers for classification and prediction of phenotypes显示文摘In general,a disease manifests not from malfunction of individual molecules but from failure of the relevant system or network,which can be considered as a set of interactions or edges among molecules.Thus,instead of individual molecules,networks or edges are stable forms to reliably characterize complex diseases.This paper reviews both traditional node biomarkers and edge biomarkers,which have been newly proposed.These biomarkers are classified in terms of their contained information.In particular,we show that edge and network biomarkers provide novel ways of stably and reliably diagnosing the disease state of a sample.First,we categorize the biomarkers based on the information used in the learning and prediction steps.We then briefly introduce conventional node biomarkers,or molecular biomarkers without network information,and their computational approaches.The main focus of this paper is edge and network biomarkers,which exploit network information to improve the accuracy of diagnosis and prognosis.Moreover,by extracting both network and dynamic information from the data,we can develop dynamical network and edge biomarkers.These biomarkers not only diagnose the immediate pre-disease state but also detect the critical molecules or networks by which the biological system progresses from the healthy to the disease state.The identified critical molecules can be used as drug targets,and the critical state indicates the critical point of disease control.The paper also discusses representative biomarker-based methods. | ZENG Tao ZHANG WanWei YU XiangTian LIU XiaoPing LI MeiYi LIU Rui CHEN LuoNan | 2014 | Science China(Life Sciences)2014,57,11: | 5 |
| 3 | Surface and intrinsic contributions to extinction properties of ZnSe quantum dots显示文摘This work studies extinction properties of ZnSe quantum dots terminated with either Se-surface or Zn-surface(Se-ZnSe or Zn-ZnSe QDs).In addition to commonly observed photoluminescence quenching by anionic surface sites,Se-ZnSe QDs are found to show drastic signatures of Se-surface states in their UV-visible(Vis)absorption spectra.Similar to most QDs reported in literature,monodisperse Zn-ZnSe QDs show sharp absorption features and blue-shifted yet steep absorption edge respect to the bulk bandgap.However,for monodisperse Se-ZnSe QDs,all absorption features are smeared and a low-energy tail is identified to extend to an energy window below the bulk ZnSe bandgap.Along increasing their size,a cyclic growth of ZnSe QDs switches their surface from Zn-terminated to Se-terminated ones,which confirms that the specific absorption signatures are reproducibly repeated between those of two types of the QDs.Though the extinction coefficients per unit of Se-ZnSe QDs are always larger than those of Zn-ZnSe QDs with the same size,both of them approach the same bulk limit.In addition to contribution of the lattice,extinction coefficients per nanocrystal of Zn-ZnSe QDs show an exponential term against their sizes,which is expected for quantum-confinement enhancement of electron-hole wavefunction overlapping.For Se-ZnSe QDs,there is the third term identified for their extinction coefficients per nanocrystal,which is proportional to the square of size of the QDs and consistent with surface contribution. | Shangxin Lin Jiongzhao Li Chaodan Pu Hairui Lei Meiyi Zhu Haiyan Qin Xiaogang Peng | 2020 | Nano Research2020,13,3: | 5 |
| 4 | Whole exome sequencing identifies an AMBN missense mutation causing severe autosomal-dominant amelogenesis imperfecta and dentin disorders显示文摘Tooth development is a complex process that involves precise and time-dependent orchestration of multiple genetic, molecular,and cellular interactions. Ameloblastin(AMBN, also named 'amelin' or 'sheathlin') is the second most abundant enamel matrix protein known to have a key role in amelogenesis. Amelogenesis imperfecta(AI [MIM: 104500]) refers to a genetically and phenotypically heterogeneous group of conditions characterized by inherited developmental enamel defects. The hereditary dentin disorders comprise a variety of autosomal-dominant genetic symptoms characterized by abnormal dentin structure affecting either the primary or both the primary and secondary teeth. The vital role of Ambn in amelogenesis has been confirmed experimentally using mouse models. Only two cases have been reported of mutations of AMBN associated with non-syndromic human AI. However, no AMBN missense mutations have been reported to be associated with both human AI and dentin disorders.We recruited one kindred with autosomal-dominant amelogenesis imperfecta(ADAI) and dentinogenesis imperfecta/dysplasia characterized by generalized severe enamel and dentin defects. Whole exome sequencing of the proband identified a novel heterozygous C-T point mutation at nucleotide position 1069 of the AMBN gene, causing a Pro to Ser mutation at the conserved amino acid position 357 of the protein. Exfoliated third molar teeth from the affected family members were found to have enamel and dentin of lower mineral density than control teeth, with thinner and easily fractured enamel, short and thick roots, and pulp obliteration. This study demonstrates, for the first time, that an AMBN missense mutation causes non-syndromic human AI and dentin disorders. | Ting Lu Meiyi Li Xiangmin Xu Jun Xiong Cheng Huang Xuelian Zhang Aiqin Hu Ling Peng Decheng Cai Leitao Zhang Buling Wu Fu Xiong | 2018 | International Journal of Oral Science2018,10,4: | 3 |
| 5 | Dynamic edge-based biomarker non-invasively predicts hepatocellular carcinoma with hepatitis B virus infection for individual patients based on blood testing显示文摘Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is a major cause of cancer-related deaths in Asia and Africa. Developing effective and non-invasive biomarkers of HCC for individual patients remains an urgent task for early diagnosis and convenient monitoring. Analyzing the transcriptomic profiles of peripheral blood mononuclear cells from both healthy donors and patients with chronic HBV infection in different states (i.e. HBV carrier, chronic hepatitis B, cirrhosis, and HCC), we identified a set of 19 candidate genes according to our algorithm of dynamic network biomarkers. These genes can both characterize different stages during HCC progression and identify cirrhosis as the critical transition stage before carcinogenesis. The interaction effects (i.e. coexpressions) of candidate genes were used to build an accurate prediction model: the so-called edge-based biomarker. Considering the convenience and robustness of biomarkers in clinical applications, we performed functional analysis, validated candidate genes in other independent samples of our collected cohort, and finally selected COL5A1, HLA-DQB1, MMP2, and CDK4 to build edge panel as prediction models. We demonstrated that the edge panel had great performance in both diagnosis and prognosis in terms of precision and specificity for HCC, especially for patients with alpha-fetoprotein-negative HCC. Our study not only provides a novel edge-based biomarker for non-invasive and effective diagnosis of HBV-associated HCC to each individual patient but also introduces a new way to integrate the interaction terms of individual molecules for clinical diagnosis and prognosis from the network and dynamics perspectives. | Yiyu Lu Zhaoyuan Fang Meiyi Li Chen Qian Tao Zeng Lina Lu Qilong Chen Hui Zhang Qianmei Zhou Yan Sun Xuefeng Xue Yiyang Hu Luonan Chen Shibing Su | 2019 | Journal of Molecular Cell Biology2019,11,8: | 3 |

| 10 | Differences in vascular endothelial function and serum proteome between obese people with phlegm-dampness constitution and balanced constitution显示文摘OBJECTIVE:To evaluate the extent of vascular endothelial dysfunction and preliminary identify serum protein biomarkers associated with obese individuals at risk for cardiovascular disease(CVD).METHODS:Fifteen obese volunteers with the phlegmdampness constitution or balanced constitution were recruited for this study respectively.The clinical baseline data was collected,and the vascular endothelial function was evaluated using the EndoPAT?.Blood samples were collected for the serum proteome analysis.The differences in the serum protein expression levels between the two groups were detected and the protein interaction network analysis,correlation analysis,receiver operating characteristic(ROC)curve analysis,and random forest model investigation were conducted.RESULTS:There were no statistical differences found in the baseline data.For vascular endothelial function,the reactive hyperemia index(RHI)of the phlegm-dampness constitution obese group was significantly lower than that of the balanced constitution obese group(1.46±0.30 vs 2.82±0.78,P<0.0001),indicating vascular endothelial dysfunction.There are 66 differentially expressed serum proteins between the two groups.apolipoprotein A2(Apo A2),angiotensin-converting enzyme 2(ACE-2),interleukin-33(IL-33),and forkhead box P3(FoxP3)showed significant differences and area under curve values of their ROC curves were greater than 0.7 and correlated significantly with RHI.CONCLUSION:Vascular endothelial dysfunction was present in the phlegm-dampness constitution obese group.Thus,alterations in the expression levels of key serum proteins,including Apo A2,ACE-2,IL-33,and Fox P3 could serve as potential biomarkers in the obese population at risk of CVD. | ZHU Linghui SUN Ziwei GUAN Yuanyuan LIU Meiyi ZHENG Yi YU Ruoxi WANG Qi LI Lingru | 2024 | Journal of Traditional Chinese Medicine2024,44,1: | 0 |
| 11 | Women's Dress in Modern China (2)显示文摘THE changes in collars, sleeves and lace of women’s clothing should be regarded as changes in form. But the early 20th century also saw changes in the ideology of and attitudes towards women’s fashions. The first striking change was that women began to adopt men’s fashions. Some women who struggled for emancipation chose to dress as men in order to change the image of women as delicate and frail. Around 1903, Qiu Jin, a famous woman fighter of the Chinese democratic revolution, lived in Beijing. A Japanese friend was deeply impressed | LI MEIYI LIU QIAN | 1996 | Women of China1996,,10: | 0 |

| 13 | An innovative method used for the identification of N-glycans on soybean allergenβ-conglycinins显示文摘β-Conglycinin is one of the major allergens existed in soybean.N-Glycans attached to theβ-conglycinin influenced the immunoreactivity and antigen presenting efficiency ofβ-conglycinin.In this study,we described a new method used to release and collect the N-glycans fromβ-conglycinin,and the N-glycans existed in linear epitopes ofβ-conglycinin were identified.Glycopeptides hydrolyzed fromβ-conglycinin were purified by cotton hydrophilic chromatography.Trifluoromethylsulfonic acid was then used to release glycans from glycopeptides,and new glycopeptides containing one single N-acety1-D-glucosamine(G1 cNAc)moiety were then utilized for mass spectrometry.Five glycosylation sites(Asn-199,Asn-455,Asn-215,Asn-489 and Asn-326)and 22 kinds of glycopeptides were identified.It is noteworthy that the peptide VVN^(#)ATSNL(where^(#)represents for the glycosylation site)was analyzed to be both glycopeptide and linear epitope.Our results provided a new method for the N-glycoform analysis of food allergens,and laid a foundation for understanding the relationship between glyco sylation and food allergy. | Cheng Li Yang Tian Jianli Han Yu Lu Meiyi Zou Yue Jia Chengjian Wang Linjuan Huang Zhongfu Wang | 2023 | Food Science and Human Wellness2023,12,3: | 0 |
| 14 | Neuritin affects the activity of neuralized-like 1 by promoting degradation and weakening its affinity for substrate显示文摘Neuritin plays a key role in neural development and regeneration by promoting neurite outgrowth and synapse maturation.Our previous research revealed the mechanism by which neuritin inhibits Notch signaling through interaction with neuralized-like 1(Neurl1)to promote neurite growth.However,how neuritin regulates Notch signaling through Neurl1 has not been elucidated.Here,we first confirm that neuritin is an upstream regulator of Neurl1 and inhibits Notch signaling through Neurl1.Neurl1 is an E3 ubiquitin ligase that can promote ubiquitination and endocytosis of the Notch1 ligand Jagged1.Therefore,we observe the effect of neuritin on the ligase activity of Neurl1.The results indicate that neuritin inhibits Neurl1 activity by reducing the ubiquitination level and endocytosis of the target protein Jagged1.Moreover,we find that decreased activity of Neurl1 results in reduced expression of Notch receptor Notch intracellular domain(NICD)and downstream target gene hairy and enhancer of split-1(HES1).Furthermore,we investigate how neuritin affects Neurl1 enzyme activity.The results show that neuritin not only weakens the affinity between Neurl1 and Jagged1 but also promotes the degradation of Neurl1 by the 26S proteasome pathway.Taken together,our results suggest that neuritin negatively regulates Notch signaling by inhibiting the activity of Neurl1,promoting the degradation of Neurl1 and weakening the affinity of Neurl1 for Jagged1.Our study clarifies the molecular mechanisms of neuritin in regulating the Notch signaling pathway and provides new clues about how neuritin mediates neural regeneration and plasticity. | Jingling Zhu Yu Li Chen Zhong Meiyi Zhu Yan Zheng Anying Xiong Pingping Meng Liya Shan Yang Li Jin Huang | 2023 | Acta Biochimica et Biophysica Sinica2023,55,10: | 0 |
