2The Role of Exportin-5 in MicroRNA Biogenesis and Cancer显示文摘Micro RNAs(mi RNAs) are conserved small non-coding RNAs that play an important role in the regulation of gene expression and participate in a variety of biological processes. The biogenesis of mi RNAs is tightly controlled at multiple steps, such as transcription of mi RNA genes,processing by Drosha and Dicer, and transportation of precursor mi RNAs(pre-mi RNAs) from the nucleus to the cytoplasm by exportin-5(XPO5). Given the critical role of nuclear export of premi RNAs in mi RNA biogenesis, any alterations of XPO5, resulting from either genetic mutation,epigenetic change, abnormal expression level or posttranslational modification, could affect mi RNA expression and thus have profound effects on tumorigenesis. Importantly, XPO5 phosphorylation by ERK kinase and its cis/trans isomerization by the prolyl isomerase Pin1 impair XPO50 s nucleo-to-cytoplasmic transport ability of pre-mi RNAs, leading to downregulation of mature mi RNAs in hepatocellular carcinoma. In this review, we focus on how XPO5 transports pre-mi RNAs in the cells and summarize the dysregulation of XPO5 in human tumors.Ke Wu Juan He Wenchen Pu Yong Peng 2018Genomics, Proteomics & Bioinformatics2018,16,2:8

4Effect of Yiqihuoxue prescription on myocardial energy metabolism after myocardial infarction via cross talk of liver kinase B1-depen-dent Notch1 and adenosine 5'-monophosphate-activated protein kinase显示文摘OBJECTIVE: To investigate the effect of Yiqihuoxue prescription(YQHX) from Traditional Chinese Medicine(TCM) on myocardial glucose and lipid metabolism after myocardial infarction via the cross talk between the liver kinase B1(LKB1)-dependent Notch1 and adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK). YQHX was prepared with substances with properties that benefit, to activate blood circulation based on the TCM theory.METHODS: Animal models of myocardial infarction were established by ligating Sprague Dawley rats' left anterior descending coronary arteries. The animals were randomly divided into a myocardial infarction(MI) group, a YQHX group, a perindopril group, a γ-secretase inhibitor, Notch signal inhibitor(DAPT) group, a DAPT+YQHX group and a sham group. The related drugs were administered on the second day after operation, and changes in the relevant indexes were examined on weeks 1 and 4.Changes in cardiac structure and function were examined by echocardiography. The glucose and free fatty acids(FFA) were examined by ELISA. The expression of Notch, LKB1 and AMPK m RNA was examined by a real-time fluorescence quantitative method. The expression of glucose transporter 4(GLUT4), and the expression of total acetyl-Co A carboxylase(ACC) and its phosphorylation were examined by western blotting.RESULTS: Compared with the sham group, the expression of Notch, LKB1 and AMPK m RNA in the MI group was lower. Compared with the MI group, the expression of these m RNAs in the YQHX and perindopril groups was higher, and their expression in the DAPT group was lower. At all time points, the protein expression of GLUT4 and p ACC decreased in the MI group. On week 1, the expression of p ACC protein was higher. In the DAPT group, the expression of p ACC protein decreased. Compared with the YQHX group, the expression of p ACC protein in the DAPT + YQHX group was lower. On week 4,compared with the MI group, the expression of GLUT4 protein in the YQHX group and the perindo-pril group was higher. The expression of GLUT4 protein in the DAPT group decreased. Compared with the YQHX group, the expression of GLUT4 protein in the DAPT+YQHX group was lower. There was no significant difference in the expression of ACC protein between the groups.CONCLUSION: YQHX promoted cross talk between the LKB1-dependent Notch1 and AMPK in myocardial tissue after myocardial infarction. Furthermore,it regulated the glucose and lipid metabolism of cardiomyocytes at different time points, thereby ameliorating the cardiac energy metabolism via different mechanisms and protecting the heart.Wu Jiangong Chen Xi Guo Shuwen Liu Wenchen Zhang Lu Li Fanghe Wu Jiani Huang Xiaolou Cai Qian Tan Xiaobo Wang Hui 2017Journal of Traditional Chinese Medicine2017,37,3:7
5Analysis of abnormal texture formation and strengthening mechanism in an extruded Mg-Gd-Y-Zn-Zr alloy显示文摘A Mg-Gd-Y-Zn-Zr magnesium alloy with different initial states was extruded under different extrusion parameters.The effect of solution treatment and extrusion parameters on the microstructure,texture and mechanical properties were analyzed in detail,and the abnormal texture formation and strengthening mechanism was revealed.When extruded at low temperature and small extrusion ratio,the bimodal microstructure consisting of fine dynamically recrystallized grains and coarse deformed grains occurred both in the as-cast alloy and solution-treated alloy.When the extrusion temperature and extrusion ratio were increased,the amount and size of dynamically recrystallized grains increased and the grain size of the solution-treated alloy showed higher growth rate.Furthermore,an abnormal texture with<0001>parallel with extrusion direction developed due to the occurrence of non-basal slip and continuous dynamic recrystallization.This could be enhanced by solution treatment,high temperature,and large extrusion ratio.Both the as-cast alloy and solution-treated alloy exhibited the highest tensile strength after extrusion at 300℃with an extrusion ratio of 9.Grain refinement was the main strengthening mechanism utilized in both the as-cast alloy and the solution-treated alloy.Work hardening played an important role in the sample extruded at low temperature and small extrusion ratio,with the highest contribution of about 33 MPa after extrusion at 300℃with an extrusion ratio of 9.Texture strengthening contributed more in the sample extruded at high temperature and large extrusion ratio,but no more than 24.1 MPa.Solution strengthening was another strengthening mechanism in the extruded as-cast alloy,especially at high temperature and large extrusion ratio(no more than 9 MPa).Xueze Jin Wenchen Xu Zhongze Yang Can Yuan Debin Shan BugangTeng Bo Cheng Jin 2020Journal of Materials Science & Technology2020,42,10:7
6Selective catalytic reduction of NO by C_2H_2 over Ce-Al_2O_3 catalyst with rate-determining step of NO oxidation显示文摘Ce-Al2O3 catalysts prepared by co-precipitation are investigated both in NO oxidation by O2 and in selective catalytic reduction of NO by C2H2(C 2 H 2-SCR).It is found that C2H2-SCR is initiated and controlled by NO oxidation to NO 2 over Al2O3.Ce loading on Al2O3 is almost inactive for NO oxidation below 350 C,since NO2 strongly adsorbs on cerium oxide,leading to the active sites being blocked,which was characterized by temperature-programmed desorption of NO and NO 2 and Fourier transform infrared spectroscopy after NO+O 2 coadsorption over the samples.However,in the case of C2H2-SCR,Ce loading on Al 2 O 3 significantly improves the reaction by accelerating the NO oxidation step in the temperature range of 250-450 C,since the nitrate species produced by NO 2 adsorption is an active intermediate required by C2H 2-SCR.Suhua Yan Xinping Wang Wenchen Wang Zequn Liu Jiahao Niu 2012Journal of Natural Gas Chemistry2012,21,3:6

8Exosomes rewire the cartilage microenvironment in osteoarthritis:from intercellular communication to therapeutic strategies显示文摘Osteoarthritis(OA)is a prevalent degenerative joint disease characterized by cartilage loss and accounts for a major source of pain and disability worldwide.However,effective strategies for cartilage repair are lacking,and patients with advanced OA usually need joint replacement.Better comprehending OA pathogenesis may lead to transformative therapeutics.Recently studies have reported that exosomes act as a new means of cell-to-cell communication by delivering multiple bioactive molecules to create a particular microenvironment that tunes cartilage behavior.Specifically,exosome cargos,such as noncoding RNAs(ncRNAs)and proteins,play a crucial role in OA progression by regulating the proliferation,apoptosis,autophagy,and inflammatory response of joint cells,rendering them promising candidates for OA monitoring and treatment.This review systematically summarizes the current insight regarding the biogenesis and function of exosomes and their potential as therapeutic tools targeting cell-to-cell communication in OA,suggesting new realms to improve OA management.Yuangang Wu Jiao Li Yi Zeng Wenchen Pu Xiaoyu Mu Kaibo Sun Yong Peng Bin Shen 2022International Journal of Oral Science2022,14,3:4
9Reexamination of Radiolarian Biostratigraphy in Permian in Pelagic Chert Sequences at Dachongling Section, South China显示文摘Permian radiolarian biostratigraphy was reexamined in the bedded chert section in Qinzhou area of southeast Guangxi Zhuang Autonomous Region, South China. On the basis of the analyses of characteristic radiolarian composition, six radiolarian zones are recognized, namely, Pseudoalbaillella longtanensis Zone, Pseudoalbaillella globosa Zone, Follicucullus monacanthus Zone, Follicucullus scholasticus Zone, Follicucullus charveti Zone and Neoalbaillella ornithoformis Zone, in ascending order. Correlation of these radiolarian zones with those in Japan is presented. The Neoalbaillella ornithoformis Zone was firstly discovered in Dachongling Section, which may indicate that pelagic chert of the late Permian existed there, according to the co occurring conodonts.Sun Dongying Xia Wenchen Liu Dongjie Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074 2002Journal of China University of Geosciences2002,13,3:3
10Three-source partitioning of soil respiration by ^(13)C natural abundance and its variation with soil depth in a plantation显示文摘Partitioning soil respiration into three components is vital to identify CO_2 sink or source and can help us better understand soil carbon dynamics. However, knowledge about the influences of soil depth and the priming effect on soil respiration components under field has been limited. Three components of soil respiration(root respiration, rhizomicrobial respiration and basal respiration) in a plantation in the hilly area of the North China were separated by the 13 C natural abundance method. The results showed that the average proportions of rhizomicrobial respiration, root respiration and basal respiration at the 25–65 cm depths were about 14, 23 and 63 %, respectively. Three components of soil respiration varied with soil depth, and root respiration was the main component of soil respiration in deeper soil. The priming effect was obvious for the deep soil respiration, especially at the 40–50 cm depth. Thus, depth and priming effect should be taken into account to increase the accuracy of estimations of soil carbon flux.Wenchen Song Xiaojuan Tong Jinsong Zhang Ping Meng 2016Journal of Forestry Research2016,27,3:3
11Periostin mediates epithelial-mesenchymal transition through the MAPK/ERK pathway in hepatoblastoma显示文摘Objective: The aim of the present study was to analyze the prognostic factors in patients with hepatoblastoma(HB) in our single center and to evaluate periostin(POSTN) expression in HB and its association with clinicopathological variables. In addition, the underlying mechanism of how POSTN promotes HB progression was discussed.Methods: POSTN expression was investigated in HB tumors by immunohistochemistry(IHC), immunofluorescence(IF) and Western blot(WB). The association among POSTN expression, clinicopathological features and overall survival(OS) was also evaluated. The migration and adhesion ability of HB cells were measured using chemotaxis and cell-matrix adhesion assays,respectively. Epithelial-mesenchymal transition(EMT)-associated markers and activation of the ERK pathway were detected by WB.Results: HB patients had poor prognosis which displayed lymph node metastasis, vascular invasion, POSTN and vimentin expression. POSTN expression was also associated with lymph node metastasis. Furthermore, overexpressed POSTN promoted migration and the adhesive ability of HB cells in vitro. In addition, we demonstrated that POSTN activated the MAPK/ERK pathway, upregulated the expression of Snail and decreased the expression of OVOL2. Finally, POSTN promoted the expression of EMT-associated markers.Conclusions: POSTN might modulate EMT via the ERK signaling pathway, thereby promoting cellular migration and invasion.Our study also suggests that POSTN may serve as a therapeutic biomarker in HB patients.Lu Chen Xiangdong Tian Wenchen Gong Bo Sun Guangtao Li Dongming Liu Piao Guo Yuchao He Ziye Chen Yuren Xia Tianqiang Song Hua Guo 2019Cancer Biology & Medicine2019,16,1:3
12Characteristics of Albaillella (Albaillellarian,Radiolarian) Fauna from Guadalupian to Lopingian Series in Permian,South China显示文摘On the basis of establishment of radiolarian biostratigraphy and conodont biostratigraphy, a radiolarian Albaillella fauna in the transitional environment from Guadalupian to Lopingian Series in Permian was found at a pelagic chert section in southeast Guangxi, South China. Radiolarian Albaillella is one of the most sensitive biology to the transitional environment. The Albaillella fauna shows an ecological evolutionary process from Guadalupian to Lopingian: declined stage-recovery stage-flourishing stage. The study of characteristics of the Albaillella fauna in the transitional environment may provide more information, not only for the subdivision and correlation of a high-resolution biostratigraphy, but also for influence of radiolarian Albaillella fauna on the pre-Lopingian mass extinction.Sun Dongying Xia Wenchen Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074 2003Journal of China University of Geosciences2003,14,4:2
13Microfluidic fabrication of water-in-water droplets encapsulated in hydrogel microfibers显示文摘Aqueous microdroplets are of significant interest in biological fields, while the employment of water-inoil (w/o) emulsion and lack of spatial control precluded its widespread application. Herein a novel microfluidic approach is developed to generate water-in-water (w/w) microdroplets embedded in hydrogel microfibers. Aqueous two phase system (ATPS) is applied to generate w/w droplets, and alginate is introduced to continuous phase to form microfibers, which offers spatial restriction and manipulation possibility to droplets. The size and pattern of aqueous droplets can be precisely controlled, and immobilization within hydrogel fiber facilitates easy manipulation and observation. The microdroplets surrounded by hydrophilic environment can act as a cell-cell interaction model, and their potential for biological and environmental applications are demonstrated by long-term culture of encapsulated cells and water remediation of Bacillus subtilis.Chenguang Liu Wenchen Zheng Ruoxiao Xie Yupeng Liu Zhe Liang Guoan Luo Mingyu Ding Qionglin Liang 2019Chinese Chemical Letters2019,30,2:2
14Fabrication of electrochemically-modified BiVO_(4)-MoS_(2)-Co_(3)O_(4)composite film for bisphenol A degradation显示文摘A new electrochemically-modified BiVO_(4)-MoS_(2)-Co_(3)O_(4)(represented as E-BiVO_(4)-MoS_(2)-Co_(3)O_(4))thin film electrode was successfully synthesized for environmental application.MoS_(2)and Co_(3)O_(4)were grown on the surface of Bi VO 4 to obtain BiVO_(4)-MoS_(2)-Co_(3)O_(4).E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)film was achieved by further electrochemical treatment of BiVO_(4)-MoS_(2)-Co_(3)O_(4).The asprepared E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)exhibited significantly enhanced photoelectrocatalytic activity.The photocurrent density of E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)thin film is 6.6 times that of Bi VO 4 under visible light irradiation.The degradation efficiency of E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)for bisphenol A pollutant was 81.56%in photoelectrochemical process.The pseudo-first order reaction rate constant of E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)film is 3.22 times higher than that of Bi VO 4.And its reaction rate constant in photoelectrocatalytic process is 14.5 times or 2 times that in photocatalytic or electrocatalytic process,respectively.The improved performance of E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)was attributed to the synergetic effects of the reduction of interfacial charge transfer resistance,the formation of oxygen vacancies and sub-stoichiometric metal oxides and higher separation efficiency of photogenerated electron-hole pairs.E-BiVO_(4)-MoS_(2)-Co_(3)O_(4)is a promising composite material for pollutants removal.Yanqing Cong Wenhua Zhang Wenchen Ding Tongtong Zhang Yi Zhang Nianping Chi Qi Wang 2021Journal of Environmental Sciences2021,33,4:2

16Conodont Biostratigraphy across the Permian-Triassic Boundary at the Xinmin Section,Guizhou,South China显示文摘A continuous sedimentation at the Xinmin Section, Anshun, Guihzou Province, with the Upper Permian Talung Formation dominated by bedded siliceous rocks, and the Lower Triassic Luolou Formation consisting mudstones and marls as well as siliceous mudstones at its basal part indicates that it represents a deeper-water basinal facies across the Permian-Triassic boundary. Based on a systematic conodont biostratigraphic work, nine conodont species belong to two genera have been identified in this study. It enable us to establish five conodont zones at this section, in ascending order, they are: Clarkina changxingensis Zone(beds 1-3–4-2), Clarkina yini Zone(beds 4-3–5-1-1), Clarkina meishanensis Zone(beds 5-1-2–5-2), Hindeodus changxingensis Zone(beds 5-3-1–5-3-2) and Hindeodus parvus Zone(beds 5-3-3–5-3-4), respectively. According to the first occurrence of Hindeodus parvus in bed 5-3-3, the Permian-Triassic boundary is placed at the base of bed 5-3-3. This conodont zonation of the Xinmin Section provides precise biostratigraphic framework for further investigations on the geological events across the Permian-Triassic boundary at this section. In addition, the new conodont data also reveals that several siliceous beds occurred at the basal Triassic. It provides an exception of Early Triassic Chert Gap.Ning Zhang Haishui Jiang Wenli Zhong Haohao Huang Wenchen Xia 2014Journal of Earth Science2014,25,5:2
17Research on the Characteristics of Hot Deformation in BT20 Titanium alloy and Its Optimum Spinning Temperature Range显示文摘Hot compression tests were conducted on a Gleeble-1500 simulator to investigate the hot deformation behavior of BT20 Ti alloy (Ti-6Al-2Zr-1Mo-1V) in the temperature range from 550 to 1000℃ at constant strain rate in the range of 0.01~1 s-1, and then the optimum spinning temperature range was determined. Moreover, tube spinning experiments were executed to verify the reasonability of the optimum temperature range. The results show that the flow stress declines gradually with increasing deformation temperature and decreasing strain rate. In α+β phase region the dynamic recrystallization is the main softening mechanism and in β phase region the hot deformation softening is controlled by dynamic recovery. In α+βphase region with reducing strain rate dynamic recrystallization is fully developed. The optimum temperature of hot spinning is 850~900℃ and that of warm spinning is 600~650℃.Meanwhile, at the temperature above 600℃ tubular workpieces of BT20 Ti alloy have been spun without surface cracks and microstructure inhomogeneity, which proves that the optimum spinning temperature range obtained through hot compression experiments is reasonable.Wenchen XU+, Debin SHAN, Yan LU and Chunfeng LISchool of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China 2005Journal of Materials Science & Technology2005,21,6:2
18Autophagosome activity in macrophage for atherosclerotic plaques in ApoE^-/-mice enhanced by Tiaozhi Tongmai Granules显示文摘Objective:Atherosclerosis is the fundamental pathophysiologic component of cardiovascular disease,and Tiaozhi Tongmai Granules show great efficiency in the treatment of the disease.However,the mechanism of Tiaozhi Tongmai Granules is still unclear.In this study,we have combined experiments with network pharmacology to explore the antiatherosclerosis mechanism of Tiaozhi Tongmai Granules.Method:120 male ApoE/mice were randomly divided into three groups:the model group,Chinese herb group and Atorvastatin group.The model group,Atorvastatin group and Chinese herb group were fed with a high-fat diet,a high-fat diet plus atorvastatin(5.1 mg/kg/d)and a high-fat diet plus Tiaozhi Tongmai Granules(16.5 g/kg/d)for 16 weeks,respectively.Atherogenesis was identified by H&E staining.The colocalization of neutral lipid stain BODIPY and microtubule-associated protein 1 light chain 3(LC3)and the colocalization of BODIPY and lysosomal-associated membrane protein 1(LAMP1)within ApoE/mice aortic plaques were tested using fluorescence confocal microscopy and the Pearson’s coefficients were calculated.To further explore the anti-atherosclerosis mechanism of Tiaozhi Tongmai Granules,the network pharmacology was used to construct the herb-compound-target network.Results:The size of the aortic lipid plaque in the Chinese herb group and Atorvastatin group were smaller compared with the model group on the 16th week.Compared with the model group on the 16th week,the BODIPY and LC3 colocalization rate,the BODIPY and LAMP1 colocalization rate of the Chinese herb group and Atorvastatin group all presented significant increase in the aortic plaque(P<.001),showing that Tiaozhi Tongmai Granules could enhance autophagosome activity in the macrophage.In the herb-compound-target network,17 active compounds and 27 targets were obtained through literature searching and using LHRI&DAVID Bioinformatics.It was found that 23 targets were correlated with the macrophage.Some of them participated in macrophage inflammatory response,and the other targets could promote/inhibit phagocytosis of the macrophage.It was hypothesized that the active compounds of Tiaozhi Tongmai Granules were acting on these targets and having y the biological effects.Conclusions:In the progression stage of atherosclerosis,Tiaozhi Tongmai Granules can still make the macrophage have higher autophagosome activity,and play a role of anti-atherogenesis.Chenglong Zheng Qing Sun Lu Zhang Shuwen Guo Min Zheng Yan Tang Jiangong Wu Jiani Wu Wenchen Liu Zhaoduo Su Xi Chen 2015Journal of Traditional Chinese Medical Sciences2015,2,3:2
19Long non-coding RNA LncKdm2b regulates cortical neuronal differentiation by cis-activating Kdm2b显示文摘The mechanisms underlying spatial and temporal control of cortical neurogenesis of the brain are largely elusive.Long non-coding RNAs(lncRNAs)have emerged as essential cell fate regulators.Here we found LncKdm2b(also known as Kancr),a lncRNA divergently transcribed from a bidirectional promoter of Kdm2b,is transiently expressed during early differentiation of cortical projection neurons.Interestingly,Kdm2b’s transcription is positively regulated in cis by LncKdm2b,which has intrinsic-activating function and facilitates a permissive chromatin environment at the Kdm2b’s promoter by associating with hnRNPAB.Lineage tracing experiments and phenotypic analyses indicated LncKdm2b and Kdm2b are crucial in proper differentiation and migration of cortical projection neurons.These observations unveiled a lncRNA-dependent machinery in regulating cortical neuronal differentiation.Wei Li Wenchen Shen Bo Zhang Kuan Tian Yamu Li Lili Mu Zhiyuan Luo Xiaoling Zhong Xudong Wu Ying Liu Yan Zhou 2020Protein & Cell2020,11,3:2
20NUMB enhances Notch signaling by repressing ubiquitination of NOTCH1 intracellular domain显示文摘The release and nuclear translocation of the intracellular domain of Notch receptor(NICD)is the prerequisite for Notch signaling-mediated transcriptional activation.NICD is subjected to various posttranslational modifications including ubiquitination.Here,we surprisingly found that NUMB proteins stabilize the intracellular domain of NOTCH1 receptor(N1ICD)by regulating the ubiquitin–proteasome machinery,which is independent of NUMB’s role in modulating endocytosis.BAP1,a deubiquitinating enzyme(DUB),was further identified as a positive N1ICD regulator,and NUMB facilitates the association between N1ICD and BAP1 to stabilize N1ICD.Intriguingly,BAP1 stabilizes N1ICD independent of its DUB activity but relying on the BRCA1-inhibiting function.BAP1 strengthens Notch signaling and maintains stem-like properties of cortical neural progenitor cells.Thus,NUMB enhances Notch signaling by regulating the ubiquitinating activity of the BAP1–BRCA1 complex.Zhiyuan Luo Lili Mu Yue Zheng Wenchen Shen Jiali Li Lichao Xu Bo Zhong Ying Liu Yan Zhou 2020Journal of Molecular Cell Biology2020,12,5:2
