| 1 | LncRNA PU.1 AS regulates arsenic-induced lipid metabolism through EZH2/Sirt6/SREBP-1c pathway显示文摘Arsenic (As) is an omnipresent metalloid toxicant,which has elicited serious environmental pollution and health risky problems.Previous studies have uncovered that the As exposure could also cause markedly reduction of serum triglycerides in mice.However,the regulation mechanisms are still largely unknown.The present study is aimed to elucidate the molecular mechanisms of lncRNAs in As-induced lipid metabolic disequilibrium.We demonstrated that lncRNA PU.1 AS was significantly induced in the liver of As-feed mice companied with lower serum triglycerides contents;further in vitro experiment confirmed that PU.1 AS regulated liver cells lipid accumulation by nile red fluorescence staining.Intensive mechanistic investigations illustrated that PU.1 AS could interact with EZH2 protein to regulate its downstream target gene expression,and Asinduced PU.1 AS attenuated EZH2-supppressed Sirt6 expression,thereafter leading to a decreased SREBP-1c protein expression,as well as the diminished synthesis of triglycerides in hepatocytes.In conclusion,this study provided a new lncRNA-related regulatory signaling pathway participating in As-induced abnormal lipid metabolism. | Zheng Dong Changying Li Chunyang Yin Ming Xu Sijin Liu Ming Gao | 2019 | Journal of Environmental Sciences2019,31,11: | 8 |
| 2 | Antimicrobial activity of silver loaded MnO_2 nanomaterials with different crystal phases against Escherichia coli显示文摘Silver-loaded MnO_2 nanomaterials(Ag/MnO_2),including Ag/α-MnO_2,Ag/β-MnO_2,Ag/γ-MnO_2and Ag/δ-MnO_2 nanorods,were prepared with hydrothermal and impregnation methods.The bactericidal activities of four types of Ag/MnO_2 nanomaterials against Escherichia coli were investigated and an inactivation mechanism involving Ag^+ and reactive oxygen species(ROS)was also proposed.The bactericidal activities of Ag/MnO_2 depended on the MnO_2 crystal phase.Among these nanomaterials,Ag/β^-MnO_2 showed the highest bactericidal activity.There was a 6-log decrease in E.coli survival number after treatment with Ag/β^-MnO_2 for120 min.The results of 5,5-dimethyl-l-pyrroline-N-oxide spin-trapping measurements by electron spin resonance indicate OH and O_2^- formation with addition of Ag/β-MnO_2,Ag/γ-MnO_2 or Ag/δ-MnO_2.The strongest peak of OH appeared for Ag/β-MnO_2,while no OH or ·O_2^-signal was found over Ag/α-MnO_2.Through analysis of electron spin resonance(ESR) and Ag+elution results,it could be deduced that the toxicity of Ag^+ eluted from Ag/MnO_2 nanomaterials and ROS played the main roles during the bactericidal process.Silver showed the highest dispersion on the surface of β-MnO_2,which promoted ROS formation and the increase of bactericidal activity.Experimental results also indicated that Ag/MnO_2 induced the production of intracellular ROS and disruption of the cell wall and cell membrane. | Lian Wang Hong He Changbin Zhang Li Sun Sijin Liu Shaoxin Wang | 2016 | Journal of Environmental Sciences2016,28,3: | 6 |
| 3 | Superatomic Aub clusters ligated by different N-heterocyclic carbenes and their ligand-dependent catalysis, photoluminescence, and proton sensitivity显示文摘We report herein a class of superatomic AU13 clusters stabilized by different N-heterocyclic carbenes(NHCs).The clusters show diverse metal surface structures,properties and functions as exemplified by:(1)the first anionic AU13 cluster[Au1g(NHC-1)sBr6],which has bulky NHC-1 ligands that lead to a rather open metal surface contributing to its high catalytic activity;(2)the tricationic cluster[Au13(NHC-2)sBr2]+which has bidentate,benzyl-rich NHC-2 ligands that make it ultra-stable and highly-luminescent,suitable for bio-imaging;and(3)by bearing two pyridyl groups on NHC-3,the dicationic cluster[Au:a(NHC-3)gClg]f+exhibits reversible and stable visible absorption and solubility responses to protonation/deprotonation cycles,making it a potential pH sensor(NHC-1=1,3-disopropylbenzimidazolin-ylidene;NHC-2=1,3-bis(1-benzyl-1H-benzimidazol-1-ium-yl)propane;NHC-3=1,3-bis(icolyI)benzimidazolin-ylidene).The study nicely demonstrates the importance of ligands in designing metal nanoclusters with desired functionalities. | Hui Shen Sijin Xiang Zhen Xu Chen Liu Xihua Li Cunfa Sun Shuichao Lin Boon K.Teo Nanfeng Zheng | 2020 | Nano Research2020,13,7: | 6 |
| 4 | Multi-perspective digital image correlation method using a single color camera显示文摘A novel 3 D digital image correlation(DIC) system based on a single three charge-couple device(3 CCD) color camera is proposed in this paper. Images from three different perspectives are captured by a 3 CCD camera using a reflective-based pseudo-vision system. These images are then separated by the different CCD channels, and the correlation algorithm for the multi-camera DIC system is adopted to evaluate the images. Compared to the conventional multi-camera DIC system, the proposed system is much more compact. In addition, the proposed system has no loss of spatial resolution, compares to the traditional single camera DIC system. The complex surface measurement ability and the measurement accuracy is significantly improved through the use of the multi-camera DIC algorithm. The principle of the proposed system is described in detail as well as the experimental setup. A series of validation tests are performed, and the results are verified with the commercial 3 D-DIC system. | WANG YongHong DAN XiZuo LI JunRui WU SiJin YANG LianXiang | 2018 | Science China(Technological Sciences)2018,61,1: | 5 |
| 5 | Primary cilia in hard tissue development and diseases显示文摘Bone and teeth are hard tissues.Hard tissue diseases have a serious effect on human survival and quality of life.Primary cilia are protrusions on the surfaces of cells.As antennas,they are distributed on the membrane surfaces of almost all mammalian cell types and participate in the development of organs and the maintenance of homeostasis.Mutations in cilium-related genes result in a variety of developmental and even lethal diseases.Patients with multiple ciliary gene mutations present overt changes in the skeletal system,suggesting that primary cilia are involved in hard tissue development and reconstruction.Furthermore,primary cilia act as sensors of external stimuli and regulate bone homeostasis.Specifically,substances are trafficked through primary cilia by intraflagellar transport,which affects key signaling pathways during hard tissue development.In this review,we summarize the roles of primary cilia in long bone development and remodeling from two perspectives:primary cilia signaling and sensory mechanisms.In addition,the cilium-related diseases of hard tissue and the manifestations of mutant cilia in the skeleton and teeth are described.We believe that all the findings will help with the intervention and treatment of related hard tissue genetic diseases. | Sijin Li Han Zhang Yao Sun | 2021 | Frontiers of Medicine2021,15,5: | 4 |
| 6 | Disruption of iron homeostasis and resultant health effects upon exposure to various environmental pollutants:A critical review显示文摘Environmental pollution has become one of the greatest problems in the world, and the concerns about environmental pollutants released by human activities from agriculture and industrial production have been continuously increasing. Although intense efforts have been made to understand the health effects of environmental pollutants, most studies have only focused on direct toxic effects and failed to simultaneously evaluate the long-term adaptive, compensatory and secondary impacts on health. Burgeoning evidence suggests that environmental pollutants may directly or indirectly give rise to disordered element homeostasis, such as for iron. It is crucially important to maintain concerted cellular and systemic iron metabolism. Otherwise, disordered iron metabolism would lead to cytotoxicity and increased risk for various diseases, including cancers. Thus, study on the effects of environmental pollutants upon iron homeostasis is urgently needed. In this review, we recapitulate the available findings on the direct or indirect impacts of environmental pollutants, including persistent organic pollutants(POPs), heavy metals and pesticides, on iron homeostasis and associated adverse health problems. In view of the unanswered questions, more efforts are warranted to investigate the disruptive effects of environmental pollutants on iron homeostasis and consequent toxicities. | Wenli Guo Jie Zhang Wenjun Li Ming Xu Sijin Liu | 2015 | Journal of Environmental Sciences2015,27,8: | 3 |
| 7 | Mesoporous carbon nanomaterials induced pulmonary surfactant inhibition,cytotoxicity,inflammation and lung fibrosis显示文摘Environmental exposure and health risk upon engineered nanomaterials are increasingly concerned. The family of mesoporous carbon nanomaterials(MCNs) is a rising star in nanotechnology for multidisciplinary research with versatile applications in electronics,energy and gas storage, and biomedicine. Meanwhile, there is mounting concern on their environmental health risks due to the growing production and usage of MCNs. The lung is the primary site for particle invasion under environmental exposure to nanomaterials. Here, we studied the comprehensive toxicological profile of MCNs in the lung under the scenario of moderate environmental exposure. It was found that at a low concentration of 10 μg/mL MCNs induced biophysical inhibition of natural pulmonary surfactant. Moreover, MCNs at similar concentrations reduced viability of J774 A.1 macrophages and lung epithelial A549 cells.Incubating with nature pulmonary surfactant effectively reduced the cytotoxicity of MCNs.Regarding the pro-inflammatory responses, MCNs activated macrophages in vitro, and stimulated lung inflammation in mice after inhalation exposure, associated with lung fibrosis.Moreover, we found that the size of MCNs played a significant role in regulating cytotoxicity and pro-inflammatory potential of this nanomaterial. In general, larger MCNs induced more pronounced cytotoxic and pro-inflammatory effects than their smaller counterparts. Our results provided valuable information on the toxicological profile and environmental health risks of MCNs, and suggested that fine-tuning the size of MCNs could be a practical precautionary design strategy to increase safety and biocompatibility of this nanomaterial. | Yunan Chen Yi Yang Bolong Xu Shunhao Wang Bin Li Juan Ma Jie Gao Yi Y.Zuo Sijin Liu | 2017 | Journal of Environmental Sciences2017,29,12: | 3 |
| 8 | Paraffin section observation of flower bud differentiation of Chimonanthus praecox in Kunming and comparison of the differentiation processes in different regions,China显示文摘Chimonanthus praecox is an important ornamental plant and cut flower material in China.It blooms in the freezing winter and its flower emits charming fragrance.However,in different region the flowering time is variable.In order to understand the flowering mechanism of Ch.praecox in the winter,we studied the flower bud differentiation in Spring City-Kunming using paraffin sectioning method in the present study.Meanwhile we compared the differentiation process difference from different regions.It was found that the temperature is the key factor for its flower bud differentiation and blossom of Ch.praecox.In the process of bud differentiation,the temperature 20℃was the optimum for inducing changes from vegetative axillary buds to reproductive buds and subsequent morphological differentiation in Ch.praecox.Furthermore in the first three differentiation periods—tepal primordial stage,staminal primordial stage and pistil primordial stage,Kunming took the shortest time to finish the process due to very rapid temperature rise to 20℃,whereas,in Zhengzhou the time for these differentiations was the longest,which may be caused by the slow temperature rise.After May,the high temperature stress forced the flower buds into the first long dormant period in all regions except Kunming.In Kunming,the average temperature was only 20–25℃,so the flower bud continued to differentiate.In all regions,Kunming is the first to complete whole flower bud differentiation even on the early August,and started the second dormancy very early but very long.In the other regions,the plants went through a shorter dormancy and the low temperature broke the dormancy rapidly.Contrarily the plants of Kunming spent a longer period for the low temperature.Thus,the low temperature less than 10℃is a key factor to breaking the second dormancy.Surely the regular effects of temperature on flower bud differentiation and blossom is very helpful for florescence regulation of Ch.praecox. | Sijin Li Nan Yang Longqing Chen | 2022 | Horticultural Plant Journal2022,8,2: | 2 |
| 9 | A non-metabolic function of hexokinase 2 in small cell lung cancer:promotes cancer cell stemness by increasing USP11-mediated CD133 stability显示文摘Background:Maintenance of cancer stem-like cell(CSC)stemness supported by aberrantly regulated cancer cell metabolism is critical for CSC self-renewal and tumor progression.As a key glycolytic enzyme,hexokinase 2(HK2)plays an instrumental role in aerobic glycolysis and tumor progression.However,whether HK2 directly contribute to CSC stemness maintenance in small cell lung cancer(SCLC)is largely unclear.In this study,we aimed to investgate whether HK2 independent of its glycolytic activity is directly involved in stemness maintenance of CSC in SCLC.Methods:Immunoblotting analyses were conducted to determine the expression of HK2 in SCLC CSCs and their differentiated counterparts.CSC-like properties and tumorigenesis of SCLC cells with or without HK2 depletion or overexpression were examined by sphere formation assay and xenograft mouse model.Immunoprecipitation and mass spectrometry analyses were performed to identify the binding proteins of CD133.The expression levels of CD133-associated and CSC-relevant proteins were evaluated by immunoblotting,immunoprecipitation,immunofluorescence,and immunohistochemistry assay.RNA expression levels of Nanog,POU5F1,Lin28,HK2,Prominin-1 were analyzed through quantitative reverse transcription PCR.Polyubiquitination of CD133 was examined by in vitro or in vivo ubiquitination assay.CD133+cells were sorted by flow cytometry using an anti-CD133 antibody.Results:We demonstrated that HK2 expression was much higher in CSCs of SCLC than in their differentiated counterparts.HK2 depletion inhibited CSC stemness and promoted CSC differentiation.Mechanistically,nonmitochondrial HK2 directly interacted with CD133 and enhanced CD133 expression without affecting CD133 mRNA levels.The interaction of HK2 and CD133 promoted the binding of the deubiquitinase ubiquitin-specific protease 11(USP11)to CD133,thereby inhibiting CD133 polyubiquitylation and degradation.HK2-mediated upregulation of CD133 expression enhanced the expression of cell renewal regulators,SCLC cell stemness,and tumor growth in mice.In addition,HK2 expression was positively correlated with CD133 expression in human SCLC specimens,and their expression levels were associated with poor prognosis of SCLC patients.Conclusions:These results revealed a critical non-metabolic function of HK2 in promotion of cancer cell stemness.Our findings provided new insights into the multifaceted roles of HK2 in tumor development. | Juhong Wang Fei Shao Yannan Yang Wei Wang Xueying Yang Renda Li Hong Cheng Sijin Sun Xiaoli Feng Yibo Gao Jie He Zhimin Lu | 2022 | Cancer Communications2022,42,10: | 2 |

| 11 | A tumor-penetrable drug nanococktail made from human histones for interventional nucleus-targeted chemophotothermal therapy of drug-resistant tumors显示文摘Nanoparticle-based chemophotothermal therapy(CPT)is a promising treatment for multidrug resistant tumors.In this study,a drug nanococktail of DIR825@histone was developed by employing doxorubicin(DOX),NIR dye IR825 and human histones for interventional nucleus-targeted CPT of multidrug resistant tumors with an interventional laser.After localized intervention,DIR825@histone penetrated tumor tissues by transcytosis,efficiently entered tumor cells and targeted the cell nuclei.DIR825@histone also exhibited good photothermal performance and thermal-triggered drug release.Efficient multidrug resistant tumor inhibition was achieved by enhanced CPT sensitization and MDR reversion via nuclear targeting.Moreover,an interventional laser assisted DIR825@histone in inhibiting multidrug resistant tumors by promoting the sufficient delivery of laser energy inside the tumor while reducing skin injury.Therefore,DIR825@histone together with this interventional nucleus-targeted CPT strategy holds great promise for treating multidrug resistant tumors. | Jianquan Guo Dongsheng Tan Chenmei Lou Shiying Guo Xing Jin Haijing Qu Lijia Jing Sijin Li | 2022 | Bioactive Materials2022,7,3: | 0 |
| 12 | 3D RNA nanocage for encapsulation and shielding of hydrophobic biomolecules to improve the in vivo biodistribution显示文摘Ribonucleic acid(RNA)nanotechnology platforms have the potential of harboring therapeutics for in vivo delivery in disease treatment.However,the nonspecific interaction between the harbored hydrophobic drugs and cells or other components before reaching the diseased site has been an obstacle in drug delivery.Here we report an encapsulation strategy to prevent such nonspecific hydrophobic interactions in vitro and in vivo based on a self-assembled three-dimensional(3D)RNA nanocage.By placing an RNA three-way junction(3WJ)in the cavity of the nanocage,the conjugated hydrophobic molecules were specifically positioned within the nanocage,preventing their exposure to the biological environment.The assembly of the nanocages was characterized by native polyacrylamide gel electrophoresis(PAGE),atomic force microscopy(AFM),and cryogenic electron microscopy(cryo-EM)imaging.The stealth effect of the nanocage for hydrophobic molecules in vitro was evaluated by gel electrophoresis,flow cytometry,and confocal microscopy.The in vivo sheathing effect of the nanocage for hydrophobic molecules was assessed by biodistribution profiling in mice.The RNA nanocages with hydrophobic biomolecules underwent faster clearance in liver and spleen in comparison to their counterparts.Therefore,this encapsulation strategy holds promise for in vivo delivery of hydrophobic drugs for disease treatment. | Congcong Xu Kaiming Zhang Hongran Yin Zhefeng Li Alexey Krasnoslobodtsev Zhen Zheng Zhouxiang Ji Sijin Guo Shanshan Li Wah Chiu Peixuan Guo | 2020 | Nano Research2020,13,12: | 0 |
| 13 | Facile discovery of red blood cell deformation and compromised membrane/skeleton assembly in Prader—Willi syndrome显示文摘Prader—Willi syndrome(PWS)is a rare congenital disease with genetic alterations in chromosome 15.Although genetic disorders and DNA methylation abnormalities involved in PWS have been investigated to a significant degree,other anomalies such as those in erythrocytes may occur and these have not been clearly elucidated.In the present study,we uncovered slight anemia in children with PWS that was associated with increased red blood cell(RBC)distribution width(RDW)and contrarily reduced hematocrit(HCT)values.Intriguingly,the increased ratio in RDW to HCT allowed sufficient differentiation between the PWS patients from the healthy controls and,importantly,with individuals exhibiting conventional obesity.Further morphologic examinations revealed a significant deformity in erythrocytes and mild hemolysis in PWS patients.Comprehensive mechanistic investigations unveiled compromised membrane skeletal assembly and membrane lipid composition,and revealed a reduced F-actin/G-actin ratio in PWS patients.We ascribed these phenotypic changes in erythrocytes to the observed genetic defects,including DNA methylation abnormalities.Our collective data allowed us to uncover RBC deformation in children with PWS,and this may constitute an auxiliary indicator of PWS in early childhood. | Yashuang Yang Guimei Li Yanzhou Wang Yan Sun Chao Xu Zhen Wei Shuping Zhang Ling Gao Sijin Liu Jiajun Zhao | 2022 | Frontiers of Medicine2022,16,6: | 0 |
| 14 | Pd@Ir-LOD multienzyme utilizing endogenous lactate consumption cooperates with photothermal for tumor therapy显示文摘Lactic acid(LA)plays a major role in the occurrence,development,and spread of cancer.Enlightened by its high accumulation in tumor site,a novel lactate oxidase(LOD)conjugated two-dimensional Pd@Ir nanoplatform(Pd@Ir-LOD,PIL)was fabricated to combine cascade reaction with photothermal for tumor therapy.In detail,the overexpressed LA in tumor microenvironment(TME)was a key factor to activate the PIL-based cascade reaction:(1)Plenty of H_(2)O_(2)could be generated from LA by the catalysis of LOD with O_(2);(2)potent·OH was produced from H_(2)O_(2)due to the peroxidase(POD)-like activity of PIL;(3)meantime,PIL’s catalase(CAT)-like activity could decompose part H_(2)O_(2)into O_(2)to achieve the purpose of LA cyclic oxidization.Moreover,the reduced glutathione(GSH)scavenging capability of PIL might protect the produced reactive oxygen species(ROS)from being cleared to further improve the cascade therapeutic effect.More importantly,PIL had excellent photothermal conversion efficiency(37.35%)and manifested a surprising temperature rising effect in tumor.Taken together,the decreasing LA concentration,accumulation of high-toxic ROS,the depletion of GSH together with the higher intra-tumoral temperature potently enhanced in vivo antitumor therapy.Therefore,a promising therapeutic tactic based on PIL integrating endogenous LA consumption,chemodynamic therapy(CDT),and photothermal therapy(PTT)has been put forward. | Zichen Ye Yun Li Jingchao Li Xinyan Hu Jinyang Zheng Gongxin Zhang Sijin Xiang Tianbao Zhu Zhide Guo Xiaolan Chen | 2024 | Nano Research2024,17,1: | 0 |
| 15 | Implicit,But Not Explicit,Emotion Regulation Relieves Unpleasant Neural Responses Evoked by High-Intensity Negative Images显示文摘Evidence suggests that explicit reappraisal has limited regulatory effects on high-intensity emotions,mainly due to the depletion of cognitive resources occupied by the high-intensity emotional stimulus itself.The implicit form of reappraisal has proved to be resource-saving and therefore might be an ideal strategy to achieve the desired regulatory effect in high-intensity situations.In this study,we explored the regulatory effect of explicit and implicit reappraisal when participants encountered low-and high-intensity negative images.The subjective emotional rating indicated that both explicit and implicit reappraisal down-regulated negative experiences,irrespective of intensity.However,the amplitude of the parietal late positive potential(LPP;a neural index of experienced emotional intensity)showed that only implicit reappraisal had significant regulatory effects in the high-intensity context,though both explicit and implicit reappraisal successfully reduced the emotional neural responses elicited by low-intensity negative images.Meanwhile,implicit reappraisal led to a smaller frontal LPP amplitude(an index of cognitive cost)compared to explicit reappraisal,indicating that the implementation of implicit reappraisal consumes limited cognitive control resources.Furthermore,we found a prolonged effect of implicit emotion regulation introduced by training procedures.Taken together,these findings not only reveal that implicit reappraisal is suitable to relieve high-intensity negative experiences as well as neural responses,but also highlight the potential benefit of trained implicit regulation in clinical populations whose frontal control resources are limited. | Yueyao Zhang Sijin Li Kexiang Gao Yiwei Li Jiajin Yuan Dandan Zhang | 2023 | Neuroscience Bulletin2023,39,8: | 0 |
| 16 | ^(18)F-FDG PET/MR Imaging for Evaluating of Obstructive Jaundice:Chinese Expert Consensus显示文摘The cause of obstructive jaundice is usually complex which renders its differential diagnosis and lesion localization challenging in clinical practice.Integrated Positron Emission tomography/Magnetic Resonance(PET/MR)offers complementary information from PET and MR in the diagnosis of obstructive jaundice and is becoming widely adopted in clinical setting.While preserving its diagnostic accuracy,it is important to standardize and streamline the clinical scan protocol of PET/MR in evaluating obstructive jaundice.Based on literature review and experience of large number of clinical cases from the author group,this article reports an expert consensus on imaging protocol optimization and case interpretation template standardization. | Lifang PANG Yushen GU Zhi YANG Zhifang WU Wei FAN Xiaohua ZHU Jun ZHAO Changjiu ZHAO Xuemei WANG Yongju GAO Li HUO Yi MO Meiyun WANG Jie LU Lingzhi HU Zheng ZHANG Feng WANG Xuemei DU Yue CHEN Jianjun LIU Zhaoping CHENG Yunlong LOU Shuzhan YAO Rong XU Sijin LI Hongcheng SHI | 2022 | Clinical Cancer Bulletin2022,1,2: | 0 |
| 17 | An atlas of glucose uptake across the entire human body as measured by the total-body PET/CT scanner:a pilot study显示文摘Glucose uptake differs in organs and tissues across the human body.To date,however,there has been no single atlas providing detailed glucose uptake profiles across the entire human body.Therefore,we aimed to generate a detailed profile of glucose uptake across the entire human body using the uEXPLORER positron emission tomography/computed tomography scanner,which offers the opportunity to collect glucose metabolic imaging quickly and simultaneously in all sites of the body.The standardized uptake value normalized by lean body mass(SUL)of 18F-fluorodeoxyglucose was used as a measure of glucose uptake.We developed a fingerprint of glucose uptake reflecting the mean SULs of major organs and parts across the entire human body in 15 healthy-weight and 18 overweight subjects.Using the segmentation of organs and body parts from the atlas,we uncovered the significant impacts of age,sex,and obesity on glucose uptake in organs and parts across the entire body.A difference was recognized between the right and left side of the body.Overall,we generated a total-body glucose uptake atlas that could be used as the reference for the diagnosis and evaluation of disordered states involving dysregulated glucose metabolism. | Weizhao Lu Zhaoping Cheng Xue Xie Kun Li Yanhua Duan Min Li Chao Ma Sijin Liu Jianfeng Qiu | 2022 | Life Metabolism2022,1,2: | 0 |
| 18 | Engineering Saccharomyces cerevisiae to produce plant benzylisoquinoline alkaloids显示文摘Benzylisoquinoline alkaloids(BIAs)are a diverse family of plant natural products with extensive pharmacological properties,but the yield of BIAs from plant is limited.The understanding of BIA biosynthetic mechanism in plant and the development of synthetic biology enable the possibility to produce BIAs through microbial fermentation,as an alternative to agriculture-based supply chains.In this review,we discussed the engineering strategies to synthesize BIAs in Saccharomyces cerevisiae(yeast)and improve BIA production level,including heterologous pathway reconstruction,enzyme engi neering,expression regulation,host engineering and fermentation engineering.We also highlight recent meta bolic engineering advances in the production of BIAs in yeast. | Jianing Han Yinan Wu Yilun Zhou Sijin Li | 2021 | aBIOTECH2021,2,3: | 0 |
| 19 | Scalable synthesis of lipid nanoparticles for nucleic acid drug delivery using an isometric channel-size enlarging strategy显示文摘Lipid nanoparticles(LNPs)have emerged as highly effective delivery systems for nucleic acid-based therapeutics.However,the broad clinical translation of LNP-based drugs is hampered by the lack of robust and scalable synthesis techniques that can consistently produce formulations from early development to clinical application.In this work,we proposed a method to achieve scalable synthesis of LNPs by scaling inertial microfluidic mixers isometrically in three dimensions.Moreover,a theoretical predictive method,which controls the mixing time to be equal across different chips,is developed to ensure consistent particle size and size distribution of the synthesized LNPs.LNPs loaded with small interfering RNA(siRNA)were synthesized at different flow rates,exhibiting consistent physical properties,including particle size,size distribution and encapsulation efficiency.This work provides a practical approach for scalable synthesis of LNPs consistently,offering the potential to accelerate the transition of nucleic acid drug development into clinical application. | Zesen Ma Haiyang Tong Sijin Lin Li Zhou Demeng Sun Baoqing Li Changlin Tian Jiaru Chu | 2024 | Nano Research2024,17,4: | 0 |
| 20 | Palladium nanoplates scotch breast cancer lung metastasis by constraining epithelial-mesenchymal transition显示文摘Metastasis accounts for the majority of cancer deaths in many tumor types including breast cancer.Epithelial-mesenchymal transition(EMT)is the driving force for the occurrence and progression of metastasis,however,no targeted strategies to block the EMT program are currently available to combat metastasis.Diverse engineered nanomaterials(ENMs)have been reported to exert promising anti-cancer effects,however,no ENMs have been designed to target EMT.Palladium(Pd)nanomaterials,a type of ENM,have received substantial attention in nanomedicine due to their favorable photothermal performance for cancer therapeutics.Herein,Pd nanoplates(PdPL)were found to be preferentially biodistributed to both primary tumors and metastatic tumors.Importantly,PdPL showed a significant inhibition of lung metastasis with and without near-infrared(NIR)irradiation.Mechanistic investigations revealed that EMT was significantly compromised in breast cancer cells upon the PdPL treatment,which was partially due to the inhibition of the transforming growth factor-beta(TGF-β)signaling.Strikingly,the PdPL was found to directly interact with TGF-βproteins to diminish TGF-βfunctions in activating its downstream signaling,as evidenced by the reduced phosphorylation of Smad2.Notably,TGF-β-independent pathways were also involved in undermining EMT and other important biological processes that are necessary for metastasis.Additionally,NIR irradiation elicited synergistic effects on PdPL-induced inhibition of primary tumors and metastasis.In summary,these results revealed that the PdPL remarkably curbed metastasis by inhibiting EMT signaling,thereby indicating the promising potential of PdPL as a therapeutic agent for treating breast cancer metastasis. | Shunhao Wang Jingchao Li Mei Chen Liting Ren Wenya Feng Lining Xu Xiaolan Chen Tian Xia Nanfeng Zheng Sijin Liu | 2021 | National Science Review2021,8,7: | 0 |
