| 2 | Effect of phosphogypsum and dicyandiamide as additives on NH_3,N_2O and CH_4 emissions during composting显示文摘A laboratory scale experiment of composting in a forced aeration system using pig manure with cornstalks was carried out to investigate the effects of both phosphogypsum and dicyandiamide (DCD, C2 H4 N4 ) as additives on gaseous emissions and compost quality. Besides a control, there were three amended treatments with different amounts of additives. The results indicated that the phosphogypsum addition at the rate of 10% of mixture dry weight decreased NH3 and CH4 emissions significantly during composting. The addition of DCD at the rate of 0.2% of mixture dry weight together with 10% of phosphogypsum further reduced the N20 emission by affecting the nitrification process. Reducing the phosphogypsum addition to 5% in the presence of 0.2% DCD moderately increased the NH3 emissions but not N20 emission. The additives increased the ammonium content and electrical conductivity significantly in the final compost. No adverse effect on organic matter degradation or the germination index of the compost was found in the amended treatments. It was recommended that phosphogypsum and DCD could be used in composting for the purpose of reducing NH3 , CH4 and N20 emissions.0ptimal conditions and dose of DCD additive during composting should be determined with different materials and composting systems in further study. | Yiming Luo Guoxue Li Wenhai Luo Frank Schuchardt Tao Jiang Degang Xu | 2013 | Journal of Environmental Sciences2013,25,7: | 28 |
| 3 | Herbal decoctosome is a novel form of medicine显示文摘Traditionally, herbal medicine is consumed by drinking decoctions produced by boiling herbs with water. The functional components of the decoction are heat stable. Small RNAs(sRNAs) were reported as a new class of functional components in decoctions. However, the mechanisms by which sRNAs survive heat treatment of the decoction and enter cells are unclear.Previous studies showed that plant-derived exosome-like nanoparticles(ELNs), which we call botanosomes, could deliver therapeutic reagents in vivo. Here, we report that heat-stable decoctosomes(ELNs) from decoctions have more therapeutic effects than the decoctions in vitro and demonstrate therapeutic efficacy in vivo. Furthermore, sRNAs, such as HJT-sRNA-m7 and PGY-sRNA-6, in the decoctosome exhibit potent anti-fibrosis and anti-inflammatory effects, respectively. Decoctosome is comprised of lipids, chemical compounds, proteins, and s RNAs. A medical decoctosome mimic is called bencaosome. A single lipid sphinganine(d22:0) identified in the decoctosome was mixed and heated with the synthesized sRNAs to form the simplest bencaosome. This simple bencaosome structure was identified by critical micelle concentration(cmc) assay that sRNAs coassembled with sphinganine(d22:0) to form the lipid layers of vesicles. The heating process facilitates co-assembly of sRNAs and sphinganine(d22:0) until a steady state is reached. The artificially produced sphinganine-HJT-sRNA-m7 and sphinganinePGY-sRNA-6 bencaosomes could ameliorate bleomycin-induced lung fibrosis and poly(I:C)-induced lung inflammation, respectively, following oral administration in mice. Our study not only demonstrates that the herbal decoctosome may represent a combinatory remedy in precision medicine but also provides an effective oral delivery route for nucleic acid therapy. | Xiaoyun Li Zhu Liang Jianchao Du Zhiqing Wang Song Mei Zhiqing Li Yan Zhao DANDan Zhao Yiming Ma Jun Ye Jiantao Xu Yu Zhao Jiahui Chang Yuhao Qin Lanlan Yu Chenxuan Wang Chengyu Jiang | 2019 | Science China(Life Sciences)2019,62,3: | 26 |
| 4 | Schisandra sphenanthera extract(Wuzhi Tablet)protects against chronic-binge and acute alcohol-induced liver injury by regulating the NRF2-ARE pathway in mice显示文摘Alcohol abuse leads to alcoholic liver disease and no effective therapy is currently available.Wuzhi Tablet(WZ), a preparation of extract from Schisandra sphenanthera that is a traditional hepatoprotective herb, exerted a significant protective effect against acetaminophen-induced liver injury in our recent studies, but whether WZ can alleviate alcohol-induced toxicity remains unclear. This study aimed to investigate the contribution of WZ to alcohol-induced liver injury by using chronic-binge and acute models of alcohol feeding. The activities of ALT and AST in serum were assessed as well as the level of GSH and the activity of SOD in the liver. The expression of CYP2E1 and proteins in the NRF2-ARE signaling pathway including NRF2, GCLC, GCLM, HO-1 were measured, and the effect of WZ on NRF2 transcriptional activity was determined. We found that both models resulted in liver steatosis accompanied by increased transaminase activities, but that liver injury was significantly attenuated by WZ. WZ administration also inhibited CYP2E1 expression induced by alcohol, and elevated the level of GSH and the activity of SOD in the liver. Moreover, the NRF2-ARE signaling pathway was activated by WZ andthe target genes were all upregulated. Furthermore, WZ significantly activated NRF2 transcriptional activity. Collectively, our study demonstrates that WZ protected against alcohol-induced liver injury by reducing oxidative stress and improving antioxidant defense, possibly by activating the NRF2-ARE pathway. | Xuezhen Zeng Xi Li Chenshu Xu Fulin Jiang Yufei Mo Xiaomei Fan Yaoting Li Yiming Jiang Dongshun Li Min Huang Huichang Bi | 2017 | Acta Pharmaceutica Sinica B2017,7,5: | 13 |

| 7 | Prognostic implications of epidermal growth factor receptor variant Ⅲ expression and nuclear translocation in Chinese human gliomas显示文摘Objective: To determine the prognostic implications and clinical significance of epidermal growth factor receptor variant Ⅲ(EGFRvⅢ) expression and EGFRvⅢ nuclear translocation in Chinese human gliomas.Methods: We retrospectively examined EGFRvⅢ expression and EGFRvⅢ nuclear translocation using immunohistochemistry in specimens of 240 Chinese patients with glioma, including 84 World Health Organization(WHO) II gliomas, 84 WHO Ⅲ gliomas and 72 glioblastomas(WHO IV). Factors that correlated with EGFRvⅢ and EGFRvⅢ nuclear translocation expression were analyzed by the Chi-square test. Kaplan-Meier methodology and Cox regression were used for the survival analysis.Results: Log-rank tests showed that patient age, Karnofsky performance scale(KPS) score, tumor grade,EGFRvⅢ expression, EGFRvⅢ nuclear translocation, 1 p/19 q codeletion, isocitrate dehydrogenase(IDH)mutation, Ki-67 labeling index and O6-methylguanine-DNA methyltransferase(MGMT) status(P<0.05) were significantly correlated with overall survival(OS) time. Multivariate Cox regression analysis revealed that patient age, tumor grade, EGFRvⅢ nuclear translocation, 1 p/19 q codeletion, and IDH mutation(P<0.05) were significantly correlated with OS. Patients with a high level of EGFRvⅢ nuclear translocation(≥7%) had both significantly shorter OS [hazard ratio(HR): 1.920, 95% confidence interval(95% CI): 1.228-3.003, P=0.004] and progression-free survival(PFS) times(HR: 1.661, 95% CI: 1.116-2.471, P=0.012) than those with a low level of EGFRvⅢ nuclear translocation(<7%).Conclusions: A high level of EGFRvⅢ nuclear translocation in glioma is an independent factor indicating a poor prognosis, but EGFRvⅢ expression is not an independent clinical prognostic factor. The level of EGFRvⅢ nuclear translocation maybe a novel and crucial prognostic biomarker in glioma. | Kaiyuan Yang Xiaohui Ren Liyuan Tao Peipei Wang Haihui Jiang Li Shen Yiming Zhao Yong Cui Mingxiao Li Song Lin | 2019 | Chinese Journal of Cancer Research2019,31,1: | 8 |
| 8 | Building a sequence map of the pig pan-genome from multiple de novo assemblies and Hi-C data显示文摘Pigs were domesticated independently in the Near East and China,indicating that a single reference genome from one individual is unable to represent the full spectrum of divergent sequences in pigs worldwide.Therefore,12 de novo pig assemblies from Eurasia were compared in this study to identify the missing sequences from the reference genome.As a result,72.5 Mb of nonredundant sequences(~3% of the genome)were found to be absent from the reference genome(Sscrofa11.1)and were defined as pan-sequences.Of the pan-sequences,9.0 Mb were dominant in Chinese pigs,in contrast with their low frequency in European pigs.One sequence dominant in Chinese pigs contained the complete genic region of the tazarotene-induced gene 3(TIG3)gene which is involved in fatty acid metabolism.Using flanking sequences and Hi-C based methods,27.7% of the sequences could be anchored to the reference genome.The supplementation of these sequences could contribute to the accurate interpretation of the 3D chromatin structure.A web-based pan-genome database was further provided to serve as a primary resource for exploration of genetic diversity and promote pig breeding and biomedical research. | Xiaomeng Tian Ran Li Weiwei Fu Yan Li Xihong Wang Ming Li Duo Du Qianzi Tang Yudong Cai Yiming Long Yue Zhao Mingzhou Li Yu Jiang | 2020 | Science China(Life Sciences)2020,63,5: | 7 |
| 9 | The histone H3 lysine-27 demethylase Jmjd3 plays a critical role in specific regulation of Th17 cell differentiation显示文摘Interleukin(IL)17-producing T helper(Th17)cells play critical roles in the clearance of extracellular bacteria and fungi as well as the pathogenesis of various autoimmune diseases,such as multiple sclerosis,psoriasis,and ulcerative colitis.Although a global transcriptional regulatory network of Th17 cell differentiation has been mapped recently,the participation of epigenetic modifications in the differentiation process has yet to be elucidated.We demonstrated here that histone H3 lysine-27(H3K27)demethylation,predominantly mediated by the H3K27 demethylase Jmjd3,crucially regulated Th17 cell differentiation.Activation of naı¨ve CD41 T cells immediately induced high expression of Jmjd3.Genetic depletion of Jmjd3 in CD41 T cells specifically impaired Th17 cell differentiation both in vitro and in vivo.Ectopic expression of Jmjd3 largely rescued the impaired differentiation of Th17 cells in vitro in Jmjd3-deficientCD41 T cells.Importantly,Jmjd3-deficient mice were resistant to the induction of experimental autoimmune encephalomyelitis(EAE).Furthermore,inhibition of the H3K27 demethylase activity with the specific inhibitor GSK-J4 dramatically suppressed Th17 cell differentiation in vitro.At the molecular level,Jmjd3 directly bound to and reduced the level of H3K27 trimethylation(me3)at the genomic sites ofRorc,which encodes the masterTh17 transcription factorRorgt,and Th17 cytokine genes such as Il17,Il17f,and Il22.Therefore,our studies established acritical role of Jmjd3-mediatedH3K27demethylation inTh17 cell differentiation andsuggest that Jmjd3 can be a novel therapeutic target for suppressing autoimmune responses. | Zhi Liu Wei Cao Longxia Xu Xi Chen Yu Zhan Qian Yang Sanhong Liu Pengfei Chen Yuhang Jiang Xiaohua Sun Yu Tao Yiming Hu Cuifeng Li Qi Wang Ying Wang Charlie Degui Chen Yufang Shi Xiaoren Zhang | 2015 | Journal of Molecular Cell Biology2015,7,6: | 6 |
| 10 | Genesis and Implications of the Composition and Sedimentary Structure of Fine-Grained Carbonate Rocks in the Shulu Sag显示文摘Fine-grained carbonate rocks, which extensively occur in the Eocene strata in the Shulu sag, Bohai Bay Basin, North China, represent an unconventional, fine-grained carbonate reservoir. However, previous studies have ignored the complexity of the lithofacies components and their formation mechanisms. Fine-grained carbonate rocks are typical reservoirs in which hydrocarbons form and gather. A better understanding of the nature of these rocks is extremely important for evaluating the quality of unconventional, fine-grained carbonate reservoirs. Various lithofacies components were discriminated in this study with a combination of petrographic observations and carbon isotope analyses. These finegrained carbonate rocks comprise terrigenous, biogenic and diagenetic materials. Terrigenous input and biologically induced precipitation are the main sources of the materials in the lake. Five lithofacies were identified based on the observations of sedimentary features(core and thin section) and mineralogical data:(1) varve-like laminated calcilutite,(2) graded laminated calcilutite,(3) interlaminated calcisiltitecalcilutite,(4) massive calcilutite, and(5) massive calcisiltite-calcarenite. Their origins were recorded by various lithofacies components, which are controlled by the interactions of physical, chemical and biological processes. This study indicated that the lithology of the bedrocks was the key factor controlling carbonate accumulation. The tectonics and climate can influence the weathering and types of lithofacies. Primary productivity controlled the precipitation of the endogenic calcite. These factors jointly determined the abundant fine-grained carbonate rocks that have accumulated in the Shulu sag. | Xiangxin Kong Zaixing Jiang Chao Han Lijing Zheng Yiming Zhang Ruifeng Zhang Jianzhang Tian | 2017 | Journal of Earth Science2017,28,6: | 6 |
| 11 | Elevating H3K27me3 level sensitizes colorectal cancer to oxaliplatin显示文摘Histone methylation is a context-dependent modification that regulates gene expression,and the trimethylation of histone H3 lysine 27(H3K27me3)usually induces gene silencing.Overcoming colorectal cancer(CRC)chemoresistance is currently a huge challenge,but the relationship between H3K27me3 modification and chemoresistance remains largely unclear.Here,we found that H3K27me3 levels positively correlated with the metastasis-free survival of CRC patients and a low H3K27me3 level predicted a poor outcome upon chemotherapeutic drug treatment.Oxaliplatin stimulation significantly induced the expression of H3K27 lysine demethylase 6A/6B(KDM6A/6B),thus decreasing the level of H3K27me3 in CRC cells.Elevation of H3K27me3 level through KDM6A/6B depletion or GSK-J4(a KDM6A/6B inhibitor)treatment significantly enhanced oxaliplatin-induced apoptosis.Conversely,when inhibiting the expression of H3K27me3 by EPZ-6438,an inhibitor of the histone methyltransferase EZH2,the proportion of apoptotic cells remarkably decreased.In addition,the combination of GSK-J4 and oxaliplatin significantly inhibited tumor growth in an oxaliplatin-resistant patient-derived xenograft model.Importantly,we revealed that oxaliplatin treatment dramatically induced NOTCH2 expression,which was caused by downregulation of H3K27me3 level on the NOTCH2 transcription initiation site.Thus,the activated NOTCH signaling promoted the expression of stemness-related genes,which resulted in oxaliplatin resistance.Furthermore,oxaliplatin-induced NOTCH signaling could be interrupted by GSK-J4 treatment.Collectively,our findings suggest that elevating H3K27me3 level can improve drug sensitivity in CRC patients. | Qi Wang Xi Chen Yuhang Jiang Sanhong Liu Hanshao Liu Xiaohua Sun Haohao Zhang Zhi Liu Yu Tao Cuifeng Li Yiming Hu Dandan Liu Deji Ye Yongzhong Liu Mingliang Wang Xiaoren Zhang | 2020 | Journal of Molecular Cell Biology2020,12,2: | 6 |
| 12 | Intergranular corrosion behavior and mechanism of the stabilized ultra-pure 430LX ferritic stainless steel显示文摘Intergranular corrosion(IGC) behavior of the stabilized ultra-pure 430 LX ferritic stainless steel(FSS) was investigated by using double loop electrochemical potentiokinetic reactivation(DL-EPR) and oxalic acid etch tests to measure the susceptibility of specimens given a two-step heat treatment. The results reveal that IGC occurs in the specimens aged at the temperature range of 600–750℃ for a short time. The aging time that is required to cause IGC decreases with the increase of aging temperature. A longer aging treatment can reduce the susceptibility to IGC. The microstructural observation shows that M(23)C6 precipitates form along the grain boundaries, leading to the formation of Cr-depleted zones. The presence of Cr-depleted zones results in the susceptibility to IGC. However, the atoms of stabilizing elements replace chromium atoms to form MC precipitates after long-time aging treatment, resulting in the chromium replenishment of Cr-depleted zones and the reduction of the susceptibility to IGC. | Peize Cheng Ning Zhong Nianwei Dai Xuan Wu Jin Li Yiming Jiang | 2019 | Journal of Materials Science & Technology2019,35,8: | 5 |
| 13 | Evaluation of Pitting Behavior on Solution Treated Duplex Stainless Steel UNS S31803显示文摘The pitting corrosion resistance of duplex stainless steels UNS S31803 annealed at different temperatures ranging from 1050 ℃ to 1200 ℃ for 24 h has been investigated by means of potentiostatic critical pitting temperature(CPT).The microstructural evolution and pit morphologies of the specimens were studied through optical microscopy and scanning electron microscopy.The potentiostatic CPT measurements show that the CPT was elevated with the annealing temperature increased from 1050 ℃ to 1150 ℃ and decreased as the temperature further increased to 1200 ℃.The specimens annealed at 1150 ℃ exhibited the highest CPTand the best pitting corrosion resistance.The pit morphologies show that the pit initiation sites transfer from austenite phase to ferrite phase as the annealing temperature increases.The results were explained by the variation of pitting resistance equivalent number(PREN) of ferrite and austenite phases as the annealing temperature was varied. | Yiming Jiang Tao Sun Jin Li Jie Xu | 2014 | Journal of Materials Science & Technology2014,30,2: | 4 |

| 15 | An Approach for Network Function Combination Based on Least Busy Placement Algorithm显示文摘Recently, integrating Softwaredefined networking(SDN) and network functions virtualization(NFV) are proposed to address the issue that difficulty and cost of hardwarebased and proprietary middleboxes management. However, it lacks of a framework that orchestrates network functions to service chain in the network cooperatively. In this paper, we propose a function combination framework that can dynamically adapt the network based on the integration NFV and SDN. There are two main contributions in this paper. First, the function combination framework based on the integration of SDN and NFV is proposed to address the function combination issue, including the architecture of Service Deliver Network, the port types representing traffic directions and the explanation of terms. Second, we formulate the issue of load balance of function combination as the model minimizing the standard deviations of all servers' loads and satisfying the demand of performance and limit of resource. The least busy placement algorithm is introduced to approach optimal solution of the problem. Finally, experimental results demonstrate that the proposed method can combine functions in an efficient and scalable way and ensure the load balance of the network. | XIE Lijun JIANG Yiming WANG Binqiang XIONG Gang CHENG Guozhen | 2016 | China Communications2016,13,S1: | 3 |
| 16 | GSH-sensitive polymeric prodrug: Synthesis and loading with photosensitizers as nanoscale chemo-photodynamic anti-cancer nanomedicine显示文摘Precisely delivering combinational therapeutic agents has become a crucial challenge for anti-tumor treatment. In this study, a novel redox-responsive polymeric prodrug(molecular weight,MW: 93.5 k Da) was produced by reversible addition-fragmentation chain transfer(RAFT) polymerization. The amphiphilic block polymer-doxorubicin(DOX) prodrug was employed to deliver a hydrophobic photosensitizer(PS), chlorin e6(Ce6), and the as-prepared nanoscale system [NPs(Ce6)] was investigated as a chemo-photodynamic anti-cancer agent. The glutathione(GSH)-cleavable disulfide bond was inserted into the backbone of the polymer for biodegradation inside tumor cells, and DOX conjugated onto the polymer with a disulfide bond was successfully released intracellularly. NPs(Ce6) released DOX and Ce6 with their original molecular structures and degraded into segments with low MWs of 41.2 k Da in the presence of GSH. NPs(Ce6) showed a chemo-photodynamic therapeutic effect to kill 4 T1 murine breast cancer cells, which was confirmed from a collapsed cell morphology, a lifted level in the intracellular reactive oxygen species, a reduced viability and induced apoptosis. Moreover, ex vivo fluorescence images indicated that NPs(Ce6) retained in the tumor, and exhibited a remarkable in vivo anticancer efficacy. The combinational therapy showed a significantly increased tumor growth inhibition(TGI,58.53%). Therefore, the redox-responsive, amphiphilic block polymeric prodrug could have a great potential as a chemo-photodynamic anti-cancer agent. | Lei Luo Yiming Qi Hong Zhong Shinan Jiang Hu Zhang Hao Cai Yahui Wu Zhongwei Gu Qiyong Gong Kui Luo | 2022 | Acta Pharmaceutica Sinica B2022,12,1: | 3 |
| 17 | Visible light-promoted, iodine-catalyzed selenoalkoxylation of olefins with diselenides and alcohols in the presence of hydrogen peroxide/air oxidant: an efficient access to α-alkoxyl selenides显示文摘Under iodine-catalyzed and visible light-irradiated aerobic conditions, selenoalkoxylation of olefins with diselenides and alcohols can be efficiently achieved to afford the useful α-alkoxyl selenides in the presence of only 0.5 equiv. of H_2O_2. Controlling the sub-stoichiometric H_2O_2 amount is crucial to avoid the non-selective over-oxidation of the diselenides that leads to the ineffective hyper-valent selenium compounds. Meanwhile, under visible light irradiation, the green, safe, and low-cost air can work as a supplemental mild oxidant in the reaction to ensure selective oxidation of the diselenides, full conversion of the reactants, and ultimately good yield of the products. | Mingxuan Liu Yiming Li Lei Yu Qing Xu Xuefeng Jiang | 2018 | Science China Chemistry2018,61,3: | 3 |
| 18 | Microstructures and mechanical properties of titanium-reinforced magnesium matrix composites: Review and perspective显示文摘Currently, many gratifying signs of progress have been made in magnesium(Mg) matrix composites(MMCs) by virtue of their high mechanical properties both at room and elevated temperatures. Although the commonly used reinforcements in MMCs are ceramic particles,they often provide improved yield and ultimate stresses by a significant loss in ductility. Therefore, hard metallic phases were introduced as alternative candidates for the manufacturing of MMCs, especially titanium(Ti). It has a high melting point, high Young’s modulus, high plasticity, low level of mutual solubility with Mg matrix, and closer thermal expansion coefficient to that of Mg metal than that of ceramic particles. It is highly preferable to provide both high ultimate stress and ductility in Mg matrix. However, many critical challenges for the fabrication of Ti-reinforced MMCs remain, such as Ti’s homogeneity, low recovery rate, and the optimization of interfacial bonding strength between Mg and Ti, etc. Meanwhile, different fabrication methods have various effects on the microstructures, mechanical properties, and the interfacial strength of Ti-reinforced MMCs. Hence, this review placed emphasis on the microstructural characteristics and mechanical properties of Ti-reinforced MMCs fabricated by different techniques. The influencing factors that govern the strengthening mechanisms were systematically compared and discussed. Future research trends, key issues, and prospects were also proposed to develop Ti-reinforced MMCs. | Hong Yang Xianhua Chen Guangsheng Huang Jiangfeng Song Jia She Jun Tan Kaihong Zheng Yiming Jin Bin Jiang Fusheng Pan | 2022 | Journal of Magnesium and Alloys2022,10,9: | 2 |
| 19 | Passivity breakdown on 436 ferritic stainless steel in solutions containing chloride显示文摘Passivity breakdown on 436 ferritic stainless steel(FSS) has been investigated in solutions containing different concentrations of chloride at 25?C and interpreted in terms of the point defect model(PDM). The measured near-normal distributions of passivity breakdown potentials for 436 FSS under experimental conditions are in good agreement with the calculated results according to the PDM. The linear dependence of breakdown potential on the square root of potential scanning rate, which was described by the PDM,provides the estimation of the critical concentration of condensed vacancies at the metal/film interface,which leads to the passivity breakdown. This value is in good agreement with that calculated from the microstructure properties of the alloy substrate and the barrier layer of the passive film. This study demonstrates the validity of the PDM in describing the passivity breakdown on 436 FSS in NaCl solutions. | Jiaming Wang Shengsheng Qian Yanhui Li Digby D.Macdonald Yiming Jiang Jin Li | 2019 | Journal of Materials Science & Technology2019,35,4: | 2 |
| 20 | Constitutive androstane receptor induced-hepatomegaly and liver regeneration is partially via yes-associated protein activation显示文摘The constitutive androstane receptor(CAR, NR3 I1) belongs to nuclear receptor superfamily.It was reported that CAR agonist TCPOBOP induces hepatomegaly but the underlying mechanism remains largely unknown. Yes-associated protein(YAP) is a potent regulator of organ size. The aim of this study is to explore the role of YAP in CAR activation-induced hepatomegaly and liver regeneration.TCPOBOP-induced CAR activation on hepatomegaly and liver regeneration was evaluated in wildtype(WT) mice, liver-specific YAP-deficient mice, and partial hepatectomy(PHx) mice. The results demonstrate that TCPOBOP can increase the liver-to-body weight ratio in wild-type mice and PHx mice.Hepatocytes enlargement around central vein(CV) area was observed, meanwhile hepatocytesproliferation was promoted as evidenced by the increased number of KI67+cells around portal vein(PV)area. The protein levels of YAP and its downstream targets were upregulated in TCPOBOP-treated mice and YAP translocation can be induced by CAR activation. Co-immunoprecipitation results suggested a potential proteineprotein interaction of CAR and YAP. However, CAR activation-induced hepatomegaly can still be observed in liver-specific YAP-deficient(Yape/e) mice. In summary, CAR activation promotes hepatomegaly and liver regeneration partially by inducing YAP translocation and interaction with YAP signaling pathway, which provides new insights to further understand the physiological functions of CAR. | Yue Gao Shicheng Fan Hua Li Yiming Jiang Xinpeng Yao Shuguang Zhu Xiao Yang Ruimin Wang Jianing Tian Frank JGonzalez Min Huang Huichang Bi | 2021 | Acta Pharmaceutica Sinica B2021,11,3: | 2 |
