| 1 | DDIT4 promotes gastric cancer proliferation and tumorigenesis through the p53 and MAPK pathways显示文摘Background:Gastric cancer(GC)is one of the most common malignancies worldwide,particularly in China.DNA damage-inducible transcript 4(DDIT4)is a mammalian target of rapamycin inhibitor and is induced by various cellular stresses;however,its critical role in GC remains poorly understood.The present study aimed to investigate the poten-tial relationship and the underlying mechanism between DDIT4 and GC development.Methods:We used western blotting,real-time polymerase chain reaction,and immunohistochemical or immunoflu-orescence to determine DDIT4 expression in GC cells and tissues.High-content screening,cell counting kit-8 assays,colony formation,and in vivo tumorigenesis assays were performed to evaluate cell proliferation.Flow cytometry was used to investigate cell apoptosis and cell cycle distribution.Results:DDIT4 was upregulated in GC cells and tissue.Furthermore,downregulating DDIT4 in GC cells inhibited proliferation both in vitro and in vivo and increased 5-fluorouracil-induced apoptosis and cell cycle arrest.In contrast,ectopic expression of DDIT4 in normal gastric epithelial cells promoted proliferation and attenuated chemosensitivity.Further analysis indicated that the mitogen-activated protein kinase and p53 signaling pathways were involved in the suppression of proliferation,and increased chemosensitivity upon DDIT4 downregulation.Conclusion:DDIT4 promotes GC proliferation and tumorigenesis,providing new insights into the role of DDIT4 in the tumorigenesis of human GC. | Feng Du Lina Sun Yi Chu Tingyu Li Chao Lei Xin Wang Mingzuo Jiang Yali Min Yuanyuan Lu Xiaodi Zhao Yongzhan Nie Daiming Fan | 2018 | Cancer Communications2018,38,1: | 10 |
| 2 | Red and Blue Lights Significantly Affect Photosynthetic Properties and Ultrastructure of Mesophyll Cells in Senescing Grape Leaves显示文摘Light quality significantly affects photosynthetic efficiency in plants. The mechanisms for how light quality affects photosynthesis in grape is poorly understood. Therefore, to investigate the effects of different light qualities on chloroplast ultrastructure and photosynthesis efficiency, two grape cultivars ‘Italia'(slower speed of leaf senescence) and ‘Centennial Seedless'(faster speed of leaf senescence) grown under protected and delayed conditions were used. The three treatments, replicated three times, were control(no supplemental lighting), red light and blue light. Chlorophyll content, net photosynthetic rate, and the ratio of F_v/F_m significantly increased in red light relative to the control. The opposite trend was observed in blue light in the early phase of leaf senescence. At later stages, physiological indexes were gradually higher than that of control, resulting in a delay in leaf senescence. Compared to the control, red and blue light both significantly increased the chlorophyll a/b ratio. Electron microscopy showed that blue light caused severe damage to the fine structure of chloroplasts at early stages of leaf senescence, but effects at later stages of leaf senescence became less severe compared to the control. The degradation of chloroplast ultrastructure was apparently delayed in red light throughout the experimental timeframe compared to other treatments. In this experiment, ‘Italia' showed higher chlorophyll content, net photosynthetic rate, ratios of F_v/F_m, chlorophyll a/b and better preserved chloroplast ultrastructure relative to ‘Centennial Seedless', resulting in a slower rate of leaf senescence. | WANG Shuai WANG Xiaodi SHI Xiangbin WANG Baoliang ZHENG Xiaocui WANG Haibo LIU Fengzhi | 2016 | Horticultural Plant Journal2016,2,2: | 10 |

| 4 | Sedimentary Characteristics of the Cretaceous in the Songliao Basin显示文摘The rupture of the lithosphere in Late Jurassic brought about the eruption of basaltic magma in the Songliao Basin. The evolution of the basin in Cretaceous progressed through six stages: pre-rift doming, extensional fracturing, fault subsidence, fault downwarping, downwarping and shringkage, resulting in the deposition of terrstrial facies nearly 10,000 m thick. There are different depositional sequences in these stages: the depositional period of the Early Cretaceous Shahezi and Yincheng Formations is the development stage of the down-faulted basin, forming a volcanic rock-alluvial fan-fan delta-lacustrine (intercalated with episodic turbidites)-swamp facies sequences; the period of the Early Cretaceous Dengluku Formation is the transformation stage of fault subsidence into fault downwarping of the basin, forming a sequence mainly of alluvial plain-lacustrine facies; the depositional period of the Early Cretaceous Quantou Formation-Late Cretaceous Nenjiang Formation is the downwarping stage of the basin, forming an alluvial plain-delta-lacustrine facies sequence; the period of the Late Cretaceous Sifangtai Formation-Mingshui Formation is the shringkage stage of the basin, forming again a sequence mainly of alluvial plain-alluvial fan and small relict lacustrine facies. These vertical depositional sequences fully display the sedimentary characteristics of a failed continental rift basin. Many facts indicate that the two large-scale lake invasions, synchronous with the global rise of sea level, which took place in the downwarping stage of the basin development, led to the connection between the lake and sea. | Liu Zhaojun, Wang Dongpo, Liu Li, Liu Wanzhu, Wang Pujun, Du Xiaodi and Yang Guang Changchun University of Earth Sciences, Changchun, Jilin Sun Sheping | 1993 | Acta Geologica Sinica(English Edition)1993,67,2: | 7 |
| 5 | The error source analysis of oil spill transport modeling: a case study显示文摘Numerical modeling is an important tool to study and predict the transport of oil spills.However,the accuracy of numerical models is not always good enough to provide reliable information for oil spill transport.It is necessary to analyze and identify major error sources for the models.A case study was conducted to analyze error sources of a three-dimensional oil spill model that was used operationally for oil spill forecasting in the National Marine Environmental Forecasting Center(NMEFC),the State Oceanic Administration,China.On June 4,2011,oil from sea bed spilled into seawater in Penglai 19–3 region,the largest offshore oil field of China,and polluted an area of thousands of square kilometers in the Bohai Sea.Satellite remote sensing images were collected to locate oil slicks.By performing a series of model sensitivity experiments with different wind and current forcings and comparing the model results with the satellite images,it was identified that the major errors of the long-term simulation for oil spill transport were from the wind fields,and the wind-induced surface currents.An inverse model was developed to estimate the temporal variability of emission intensity at the oil spill source,which revealed the importance of the accuracy in oil spill source emission time function. | LI Yan ZHU Jiang WANG Hui KUANG Xiaodi | 2013 | Acta Oceanologica Sinica2013,32,10: | 6 |
| 6 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022,15,5: | 6 |
| 7 | Silicon-coated fibrous network of carbon nanotube/iron towards stable and wideband electromagnetic wave absorption显示文摘Materials that can absorb electromagnetic(EM)wave have garnered increased attention in recent years due to their potential to mitigate the ever increasing environmental pollution by EM waves.Thanks to recent advances in micro/nanofabrication,a variety of magnetic metal-based EM absorbers have been reported.The design and synthesis of EM absorbers that exhibit efficient and wide-band absorption at small thicknesses,however,remains elusive.Here we report the design of fibrous nanostructures consisting of magnetic iron(Fe)nanoparticles and carbon nanotubes(CNTs),which exhibits a wide-band EM absorption(3.8 GHz)while maintain the thickness at 1.2 mm.In our work,we created a novel core-shell structure by immersing the highly fibrous CNT-Fe structure into solid-state silicon(SiO)matrix.Finally,the SiO-coated CNT-Fe structures exhibit good stability against air-induced oxidation and acid corrosion while maintaining high EM absorption.Overall,the results reported in this study present new avenues to absorb EM from ambient air.We believe that our work elevates the utility of EM absorbers to real-world applications such as anti-acid and oxidation ability. | Xiaodi Zhou He Han Yuchao Wang Cheng Zhang Hualiang Lv Zhichao Lou | 2022 | Journal of Materials Science & Technology2022,,26: | 4 |
| 8 | Chronostratigraphy and Stratigraphic Classification of the Cretaceous of the Songliao Basin显示文摘Isotopic ages of synsedimentary clay minerals were directly determined with the ultrasonicscattering-settlement separation-K-Ar dilution technique. The apparent age of black mudstoneis 123 Ma for the Quantou Formation, 111.9-89.0 Ma for the Qingshankou Formation and77.6-76.8 Ma for the upper part of the Nenjiang Formation. The Rb-Sr isochrone age of themuddy limestone-mudstone sequence of the lower part of the Nenjiang Formation is 81 Ma andthat of the muddy evaporite of the middle part of the Quantou Formation is 122.2 Ma. On thebasis of the above isotopic ages, the authors propose a modified scheme of stratigraphic classifi-cation of the Cretaceous of the Songliao basin. | Wang Pujun Du Xiaodi Wang Jun and Wang Dongpo 1)Geoenergy Department, Changchun University of Earth Sciences, Changchun, Jilin 2)Earth Sciences Department,Nanjing University,Nanjing,Jiangsu | 1996 | Acta Geologica Sinica(English Edition)1996,70,2: | 4 |
| 9 | Genome and transcriptome of Papaver somniferum Chinese landrace CHM indicates that massive genome expansion contributes to high benzylisoquinoline alkaloid biosynthesis显示文摘Opium poppy(Papaver somniferum)is a source of morphine,codeine,and semisynthetic derivatives,including oxycodone and naltrexone.Here,we report the de novo assembly and genomic analysis of P.somniferum traditional landrace‘Chinese Herbal Medicine’.Variations between the 2.62 Gb CHM genome and that of the previously sequenced high noscapine 1(HN1)variety were also explored.Among 79,668 protein-coding genes,we functionally annotated 88.9%,compared to 68.8%reported in the HN1 genome.Gene family and 4DTv comparative analyses with three other Papaveraceae species revealed that opium poppy underwent two whole-genome duplication(WGD)events.The first of these,in ancestral Ranunculales,expanded gene families related to characteristic secondary metabolite production and disease resistance.The more recent species-specific WGD mediated by transposable elements resulted in massive genome expansion.Genes carrying structural variations and large-effect variants associated with agronomically different phenotypes between CHM and HN1 that were identified through our transcriptomic comparison of multiple organs and developmental stages can enable the development of new varieties.These genomic and transcriptomic analyses will provide a valuable resource that informs future basic and agricultural studies of the opium poppy. | Li Pei Baishi Wang Jian Ye Xiaodi Hu Lihong Fu Kui Li Zhiyu Ni Zhenlong Wang Yujie Wei Luye Shi Ying Zhang Xue Bai Mengwan Jiang Shuhui Wang Chunling Ma Shujin Li Kaihui Liu Wanshui Li Bin Cong | 2021 | Horticulture Research2021,8,1: | 4 |
| 10 | A Superaerophobic Bimetallic Selenides Heterostructure for Efficient Industrial-Level Oxygen Evolution at Ultra-High Current Densities显示文摘Cost-effective and stable electrocatalysts with ultra-high current densities for electrochemical oxygen evolution reaction(OER)are critical to the energy crisis and environmental pollution.Herein,we report a superaerophobic three dimensional(3D)heterostructured nanowrinkles of bimetallic selenides consisting of crystalline NiSe2 and NiFe2Se4 grown on NiFe alloy(NiSe2/NiFe2Se4@NiFe)prepared by a thermal selenization procedure.In this unique 3D heterostructure,numerous nanowrinkles of NiSe2/NiFe2Se4 hybrid with a thickness of ~100 nm are grown on NiFe alloy in a uniform manner.Profiting by the large active surface area and high electronic conductivity,the superaerophobic NiSe2/NiFe2Se4@NiFe heterostructure exhibits excellent electrocatalytic activity and durability towards OER in alkaline media,outputting the low potentials of 1.53 and 1.54 V to achieve ultra-high current densities of 500 and 1000 mA cm^−2,respectively,which is among the most active Ni/Fe-based selenides,and even superior to the benchmark Ir/C catalyst.The in-situ derived FeOOH and NiOOH species from NiSe2/NiFe2Se4@NiFe are deemed to be efficient active sites for OER. | Jiaxin Yuan Xiaodi Cheng Hanqing Wang Chaojun Lei Sameer Pardiwala Bin Yang Zhongjian Li Qinghua Zhang Lecheng Lei Shaobin Wang Yang Hou | 2020 | Nano-Micro Letters2020,12,8: | 4 |
| 11 | Biomass-Derived Carbon Heterostructures Enable Environmentally Adaptive Wideband Electromagnetic Wave Absorbers显示文摘Although advances in wireless technologies such as miniature and wearable electronics have improved the quality of our lives,the ubiquitous use of electronics comes at the expense of increased exposure to electromagnetic(EM)radiation.Up to date,extensive efforts have been made to develop high-performance EM absorbers based on synthetic materials.However,the design of an EM absorber with both exceptional EM dissipation ability and good environmental adaptability remains a substantial challenge.Here,we report the design of a class of carbon heterostructures via hierarchical assembly of graphitized lignocellulose derived from bamboo.Specifically,the assemblies of nanofibers and nanosheets behave as a nanometer-sized antenna,which results in an enhancement of the conductive loss.In addition,we show that the composition of cellulose and lignin in the precursor significantly influences the shape of the assembly and the formation of covalent bonds,which affect the dielectric response-ability and the surface hydrophobicity(the apparent contact angle of water can reach 135°).Finally,we demonstrate that the obtained carbon heterostructure maintains its wideband EM absorption with an effective absorption frequency ranging from 12.5 to 16.7 GHz under conditions that simulate the real-world environment,including exposure to rainwater with slightly acidic/alkaline pH values.Overall,the advances reported in this work provide new design principles for the synthesis of high-performance EM absorbers that can find practical applications in real-world environments. | Zhichao Lou Qiuyi Wang Ufuoma IKara Rajdeep SMamtani Xiaodi Zhou Huiyang Bian Zhihong Yang Yanjun Li Hualiang Lv Solomon Adera Xiaoguang Wang | 2022 | Nano-Micro Letters2022,14,1: | 3 |

| 13 | Linear polarization holography显示文摘Polarization holography is a newly researched field,that has gained traction with the development of tensor theory.It primarily focuses on the interaction between polarization waves and photosensitive materials.The extraordinary capabil-ities in modulating the amplitude,phase,and polarization of light have resulted in several new applications,such as holo-graphic storage technology,multichannel polarization multiplexing,vector beams,and optical functional devices.In this paper,fundamental research on polarization holography with linear polarized wave,a component of the theory of polariz-ation holography,has been reviewed.Primarily,the effect of various polarization changes on the linear and nonlinear po-larization characteristics of reconstructed wave under continuous exposure and during holographic recording and recon-struction have been focused upon.The polarization modulation realized using these polarization characteristics exhibits unusual functionalities,rendering polarization holography as an attractive research topic in many fields of applications.This paper aims to provide readers with new insights and broaden the application of polarization holography in more sci-entific and technological research fields. | Jinyu Wang Xiaodi Tan Peiliang Qi Chenhao Wu Lu Huang Xianmiao Xu Zhiyun Huang Lili Zhu Yuanying Zhang Xiao Lin Jinliang Zang Kazuo Kuroda | 2022 | Opto-Electronic Science2022,1,2: | 3 |
| 14 | Dual-channel Method for Fast Long PN-code Acquisition显示文摘Long PN-code acquisition is a difficult and time-consuming task due to long code period.To accelerate acquisition,folding methods like XFAST are widely used.In highdynamic environment however,the application of those methods are largely restricted due to nonnegligible residual frequency.This paper proposes a new dual-channel method for fast acquisition of long PN-code.In the proposed method,both non-overlapping local PNcode blocks are employed to correlate with input sample block;the detection process is eased through finding the maximum value among correlation results and verification is made with all the full and partial peaks taken into account.False alarm probabilities from analysis of the verification process are derived.Both theoretical and Monte Carlo simulations reveal that,with respect to acquisition probability and mean acquisition time under the same false alarm rate,dual-channel method has advantage over zero-padding and XFAST based folding methods under certain false alarm probabilities. | FENG Wenquan XING Xiaodi ZHAO Qi WANG Zulin | 2014 | China Communications2014,11,5: | 3 |

| 16 | Establishing an experimental model of photodynamic induced anterior ischemic optic neuropathy显示文摘BACKGROUND: Scholars have supposed to establish animal models of optic neuropathy by pressing and partially amputating optic nerve, increasing intraocular pressure and injecting vasoconstrictor, etc., but the models are greatly different from anterior ischemia optic neuropathy. Therefore, a more ideal method is needed to establish animal model of anterior ischemic optic neuropathy (AION).OBJECTIVE: To establish AION models in rats, observe the functional changes of fundus, fundus fluorescein angiography (FFA), optical coherence tomography (OCT), flash visual evoked potential (F-VEP), and histopathologically confirm its reliability.DESIGN: A randomized control trial.SETTINGS: Department of Ophthalmology, Xi’an Fourth Hospital; Xi’an Institute of Ocular Fundus Diseases.MATERIALS: The experiments were carried out in the research room of Xi’an Institute of Ocular Fundus Diseases from February 2005 to May 2006. Thirty healthy male SD rats of 4-5 weeks old, weighing 140-160 g, were provided by the animal experimental center of the Fourth Military Medical University of Chinese PLA [SCXK(Military)2002-005], and those without eye disease examined by slit lamp and direct ophthalmoscope after mydriasis were enrolled. The conditions for feeding mice without special pathogen were strictly followed. The rats were randomly divided into blank control group (n =5), laser group (n =5), hematoporphyrin derivative (HPD) group and AION group (n =15), each group was numbered randomly. For each rat, the right eye was taken as the experimental eye, and the left one as the control one.METHODS: In the AION group, the rats were injected with HPD (10 mg/kg) via caudal vein, and then the optic discs were exposed to krypton red (647 nm, 80 mV) for 120 s, and the rats were in avoidance of light for 2 weeks postoperatively. Rats in the laser group were only exposed to krypton red (647 nm, 80 mV) for 120 s, and in avoidance of light for 2 weeks postoperatively; Those in the HPD group were only injected with HPD (10 mg/kg) via caudal vein; Those in the blank control group were untouched. ① Visual electrophysiological test: The F-VEP was used to evaluate the function of visual nerve. ② FFA: After mydriasis and anesthesia as describe above, the fluorescein sodium parenteral solution (1 mL/kg) was injected via caudal vein and finished within about 3 s, the time of FFA was recorded from the beginning of injection, the video sight aimed at the optic disc and the surrounding area. ③ After mydriasis and anesthesia as describe above, the rats were examined with OCT. ④ Histological observation: After hematoxylin and eosin (HE) staining, the optic disc and surrounding blood vessels of retina were observed under light microscope at high power field. MAIN OUTCOME MEASURES: The results of fundus, FFA, visual electrophysiological test and OCT detection within 90 days after model establishment were observed. RESULTS: Of the 30 rats, 1 died after anesthesia in the laser group and 2 died in the AION group respectively, and finally 27 rats were involved in the analysis of results. ① Changes in fundus: In the AION group, there was edema in upper optic disc and unclear boundary at 1 day after establishment, edema still could be observed at 6 days, and upper optic disc atrophied and appeared as pale at 90 days. ② FFA results: In the AION group, early 'low fluorescence', middle and late 'high fluorescence' were observed in upper optic disc 1 day after model establishment, and there was 'low fluorescence' at 6 days, and the low fluorescence could be observed all the time at 23 days. ③ Visual electrophysiological changes: In the AION group as compared with the control eyes, the experimental ones had prolonged F-VEP P100 latency [(71.65±8.81), (57.58±8.38) ms, t =3.148, P =0.012], and decreased wave amplitude [(4.77±1.90), (10.06±3.66) μV, t =4.082, P =0.003], and these changes lasted to 35 days after model establishment. ④ OCT results: In the AION group, the reflection surface of part nerve fiber layer was higher than the retina plane, the surface was rough and the thickness was increased at 6 days after model establishment. ⑤ Histopathological results: At 1 day after model establishment, part optic discs had highly edema, edema of nerve fibers, and loose tissue, also accompanied by the displacement of surrounding retina; At 23 days, the optic disc and surrounding nerve fiber layers became thinner, and the numbers of ganglion nuclei in the retina tissue sections were obviously decreased. These changes were not observed in the laser group, HPD group and blank control group. CONCLUSION: The changes of fundus, FFA, OCT, visual electrophysiology and histopathology confirmed that the krypton red laser irradiation (647 nm) at 2 hours after HPD was injected via caudal vein can establish more ideal animal models of AION. | Runsheng Wang Xiaodi Wang Peilin Lue Jianwei Bai Jianzhou Wang Xiaoqin Lei Xiao- liang Zhou Hongfen Sun Aizhu Pan | 2006 | Neural Regeneration Research2006,1,4: | 3 |
| 17 | Atomic manganese coordinated to nitrogen and sulfur for oxygen evolution显示文摘Lack of high-efficiency,cost-efficient,and well-stocked oxygen evolution reaction(OER)electrocatalysts is a main challenge in large-scale implementation of electrolytic water.By regulating the electronic structure of isolated single-atom metal sites,highperformance transition-metal-based catalysts can be fabricated to greatly improve the OER performance.Herein,we demonstrate single-atom manganese coordinated to nitrogen and sulfur species in two-dimensional graphene nanosheets MnNSG(NSG means N-and S-codoped graphene)as an active and durable OER catalyst with a low overpotential of 296 mV in alkaline media,compared to that of the benchmark IrO_(2) catalyst.Theoretical calculations and experimental measurements reveal that the Mn-N3S sites in the graphene matrix are the most active sites for the OER due to modified electronic structure of the Mn site by three nitrogen and one sulfur atoms coordination,which show lower theoretical overpotential than the Mn-N4 sites and over which the O–O formation step is the rate-determining step. | Xue Bai Liming Wang Bing Nan Tianmi Tang Xiaodi Niu Jingqi Guan | 2022 | Nano Research2022,15,7: | 3 |
| 18 | The determination of atmospheric phosphine in Ny-lesund显示文摘Phoshpine (PH3), a volatile and toxic gas, has been proved to commonly exist in the environment.The determination of gaseous phosphine and its emission fluxes in Ny-lesund is reported in this paper.Results showed that gaseous phosphine exist in Arctic atmosphere commonly and the concentration of phosphine ranged from 16.3-600.2 ng/m3, with the maximum concentration of phosphine in tundra areas and the minimum in surface air of ocean.The concentration of phosphine ranged from 65.79-1259 ng/m3 in colliery atmosphere at different altitudes and the maximum was found in the center of colliery.Emission fluxes of phosphine were different in various Arctic areas.Emission fluxes of phosphine from protected areas, with average concentration of 32.13±5.353 ng m–2 h–1, were higher than from other areas.And the flux of phosphine from ocean was lower. | ZHANG Rui WU Min WANG Qiang GENG JinJu YANG XiaoDi | 2010 | Chinese Science Bulletin2010,55,16: | 2 |
| 19 | Nuciferine protects against high-fat diet-induced hepatic steatosis and insulin resistance via activating TFEB-mediated autophagy——lysosomal pathway显示文摘Nonalcoholic fatty liver disease(NAFLD) is characterized by hepatic steatosis and insulin resistance and there are currently no approved drugs for its treatment.Hyperactivation of mTOR complex1(mTORCl) and subsequent impairment of the transcription factor EB(TFEB)-mediated autophagy-lysosomal pathway(ALP) are implicated in the development of NAFLD.Accordingly,agents that augment hepatic TFEB transcriptional activity may have therapeutic potential against NAFLD.The objective of this study was to investigate the effects of nuciferine,a major active component from lotus leaf,on NAFLD and its underlying mechanism of action.Here we show that nuciferine activated ALP and alleviated steatosis,insulin resistance in the livers of NAFLD mice and palmitic acid-challenged hepatocytes in a TFEB-dependent manner.Mechanistic investigation revealed that nuciferine interacts with the Ragulator subunit hepatitis B X-interacting protein and impairs the interaction of the Ragulator complex with Rag GTPases,thereby suppressing lysosomal localization and activity of mTORC1,which activates TFEB-mediated ALP and further ameliorates hepatic steatosis and insulin resistance.Our present results indicate that nuciferine may be a potential agent for treating NAFLD and that regulation of the mTORCl-TFEB-ALP axis could represent a novel pharmacological strategy to combat NAFLD. | Xiliang Du Chiara Di Malta Zhiyuan Fang Taiyu Shen Xiaodi Niu Meng Chen Bo Jin Hao Yu Lin Lei Wenwen Gao Yuxiang Song Zhe Wang Chuang Xu Zhijun Cao Guowen Liu Xinwei Li | 2022 | Acta Pharmaceutica Sinica B2022,12,6: | 2 |
