| 1 | EMT-associated microRNAs and their roles in cancer stemness and drug resistance显示文摘Epithelial-to-mesenchymal transition(EMT)is implicated in a wide array of malignant behaviors of cancers,including proliferation,invasion,and metastasis.Most notably,previou studies have indicated that both cancer stem-like properties and drug resistance were associated with EMT.Furthermore,microRNAs(miRNAs)play a pivotal role in the regulation of EMT phenotype,as a result,some miRNAs impact cancer stemness and drug resistance.Therefore,understanding the relationship between EMT-associated miRNAs and cancer stemness/drug resistance is beneficial to both basic research and clinical treatment.In this review,we preliminarily looked into the various roles that the EMT-associated miRNAs play in the stem-like nature of malignant cells.Then,we reviewed the interaction between EMT-associated miRNAs and the drugresistant complex signaling pathways of multiple cancers including lung cancer,gastric cancer,gynecologic cancer,breast cancer,liver cancer,colorectal cancer,pancreatic cancer,esophageal cancer,and nasopharyngeal cancer.We finally discussed the relationship between EMT,cancer stemness,and drug resistance,as well as looked forward to the potential applications of miRNA therapy for malignant tumors. | Guangtao Pan Yuhan Liu Luorui Shang Fangyuan Zhou Shenglan Yang | 2021 | Cancer Communications2021,41,3: | 46 |
| 2 | Explicit diagnosis of the local ozone production rate and the ozone-NOx-VOC sensitivities显示文摘In the troposphere, ozone is a harmful gas compound to both human health and vegetation. Ozone is produced from the reaction of NO_x(@NO + NO_2) and VOCs(volatile organic compounds) with light. Due to the highly nonlinear relationships between ozone and its precursors, proper ozone mitigation relies on the knowledge of chemical mechanisms. In this study, an observation-based method is used to simulate ozone formation and elucidate its controlling factors for a rural site on the North China Plain. The instantaneous ozone production rate is calculated utilizing a box model using the dataset obtained from the Wangdu campaign. First, the model was operated in a time-dependent mode to calculate the ozone production rate at each time stamp. The calculated ozone formation rate showed a diurnal average maximum value of 17 ppbv/h(1-h diurnal averaged). The contribution of individual peroxy radicals to ozone production was analyzed. In addition, the functional dependence of calculated P(O_3) reveals that ozone production was in a NO_x-limited regime during the campaign. Furthermore, the missing peroxy radical source will further extend NO_x-limited conditions to earlier in the day, making NO_xlimitation dominate more of a day than the current chemical model predicts. Finally, a multiple scenarios mode,also known as EKMA(empirical kinetic modeling approach), was used to simulate the response of P(O_3) to the imaginary change in precursor concentrations. We found that ozone production was in the NO_x-limited region. However, the use of NO_2 measured by the molybdenum converter and/or the absence of a peroxy radical source in the current chemical model could over-emphasize the VOC-limited effect on ozone production. | Zhaofeng Tan Keding Lu Huabin Dong Min Hu Xin Li Yuhan Liu Sihua Lu Min Shao Rong Su Haichao Wang Yusheng Wu Andreas Wahner Yuanhang Zhang | 2018 | Science Bulletin2018,63,16: | 25 |
| 3 | Exploring atmospheric free-radical chemistry in China:the self-cleansing capacity and the formation of secondary air pollution显示文摘Since 1971,it has been known that the atmospheric free radicals play a pivotal role in maintaining the oxidizing power of the troposphere.The existence of the oxidizing power is an important feature of the troposphere to remove primary air pollutants emitted from human beings as well as those from the biosphere.Nevertheless,serious secondary air-pollution incidents can take place due to fast oxidation of the primary pollutants.Elucidating the atmospheric free-radical chemistry is a demanding task in the field of atmospheric chemistry worldwide,which includes two kinds of work:first,the setup of reliable radical detection systems;second,integrated field studies that enable closure studies on the sources and sinks of targeted radicals such as OH and NO3.In this review,we try to review the Chinese efforts to explore the atmospheric free-radical chemistry in such chemical complex environments and the possible link of this fast gas-phase oxidation with the fast formation of secondary air pollution in the city-cluster areas in China. | Keding Lu Song Guo Zhaofeng Tan Haichao Wang Dongjie Shang Yuhan Liu Xin Li Zhijun Wu Min Hu Yuanhang Zhang | 2019 | National Science Review2019,6,3: | 26 |
| 4 | Meningeal lymphatic vessels regulate brain tumor drainage and immunity显示文摘Recent studies have shown that meningeal lymphatic vessels(MLVs),which are located both dorsally and basally beneath the skull,provide a route for draining macromolecules and trafficking immune cells from the central nervous system(CNS)into cervical lymph nodes(CLNs),and thus represent a potential therapeutic target for treating neurodegenerative and neuroinflammatory diseases.However,the roles of MLVs in brain tumor drainage and immunity remain unexplored.Here we show that dorsal MLVs undergo extensive remodeling in mice with intracranial gliomas or metastatic melanomas.RNA-seq analysis of MLV endothelial cells revealed changes in the gene sets involved in lymphatic remodeling,fluid drainage,as well as inflammatory and immunological responses.Disruption of dorsal MLVs alone impaired intratumor fluid drainage and the dissemination of brain tumor cells to deep CLNs(dCLNs).Notably,the dendritic cell(DC)trafficking from intracranial tumor tissues to dCLNs decreased in mice with defective dorsal MLVs,and increased in mice with enhanced dorsal meningeal lymphangiogenesis.Strikingly,disruption of dorsal MLVs alone,without affecting basal MLVs or nasal LVs,significantly reduced the efficacy of combined anti-PD-1/CTLA-4 checkpoint therapy in striatal tumor models.Furthermore,mice bearing tumors overexpressing VEGF-C displayed a better response to anti-PD-1/CTLA-4 combination therapy,and this was abolished by CCL21/CCR7 blockade,suggesting that VEGF-C potentiates checkpoint therapy via the CCL21/CCR7 pathway.Together,the results of our study not only demonstrate the functional aspects of MLVs as classic lymphatic vasculature,but also highlight that they are essential in generating an efficient immune response against brain tumors. | Xueting Hu Qiuping Deng Lu Ma Qingqing Li Yidong Chen Yuhan Liao Fan Zhou Chen Zhang Linlin Shao Jun Feng Tubao He Weihai Ning Yan Kong Yingqing Huo Aibin He Bing Liu Jingjing Zhang Ralf Adams Yulong He Fuchou Tang Xiuwu Bian Jincai Luo | 2020 | Cell Research2020,30,3: | 11 |
| 5 | The Cenozoic activities of Yangjiang-Yitongdong Fault: insights from analysis of the tectonic characteristics and evolution processes in western Zhujiang(Pearl) River Mouth Basin显示文摘The Yangjiang-Yitongdong Fault (YJF) is an important NW-trending regional fault, which divides the Zhujiang (Pearl) River Mouth Basin (ZRMB) into western and eastern segments. In Cenozoic, the northern continental margin of the South China Sea (SCS) underwent continental rifting, breakup, seafloor spreading and thermal subsidence processes, and the Cenozoic activities of YJF is one part of this series of complex processes. Two long NW-trending multichannel seismic profiles located on both sides of the YJF extending from the continental shelf to Continent-Ocean Boundary (COB) were used to study the tectonic and sedimentary characteristics of western ZRMB. Using the 2D-Move software and back-stripping method, we constructed the balance cross-section model and calculated the fault activity rate. Through the comprehensive consideration of tectonic position, tectonic evolution history, featured structure, and stress analysis, we deduced the activity history of the YJF in Cenozoic. The results showed that the YJF can be divided into two segments by the central uplift belt. From 65 Ma to 32 Ma, the YJF was in sinistral motion as a whole, inherited the preexisting sinistral motion of Mesozoic YJF, in which, the southern part of YJF was mainly in extension activity, controlling the formation and evolution of Yunkai Low Uplift, coupled with slight sinistral motion. From 32 Ma to 23.8 Ma, the sinistral motion in northern part of YJF continued, while the sinistral motion in southern part began to stop or shifted to a slightly dextral motion. After 23.8 Ma, the dextral motion in southern part of YJF continued, while the sinistral motion in northern part of YJF gradually stopped, or shifted to the slightly dextral motion. The shift of the YJF strike-slip direction may be related to the magmatic underplating in continent-ocean transition, southeastern ZRMB. According to the analysis of tectonic activity intensity and rift sedimentary structure, the activities of YJF in Cenozoic played a regulating role in the rift extension process of ZRMB. | Yuhan Li Rongwei Zhu Hailing Liu Xuelin Qiu Haibo Huang | 2019 | Acta Oceanologica Sinica2019,38,9: | 10 |
| 6 | Dynamic soft sensor development based on Gaussian mixture regression for fermentation processes显示文摘The dynamic soft sensor based on a single Gaussian process regression(GPR) model has been developed in fermentation processes.However,limitations of single regression models,for multiphase/multimode fermentation processes,may result in large prediction errors and complexity of the soft sensor.Therefore,a dynamic soft sensor based on Gaussian mixture regression(GMR) was proposed to overcome the problems.Two structure parameters,the number of Gaussian components and the order of the model,are crucial to the soft sensor model.To achieve a simple and effective soft sensor,an iterative strategy was proposed to optimize the two structure parameters synchronously.For the aim of comparisons,the proposed dynamic GMR soft sensor and the existing dynamic GPR soft sensor were both investigated to estimate biomass concentration in a Penicillin simulation process and an industrial Erythromycin fermentation process.Results show that the proposed dynamic GMR soft sensor has higher prediction accuracy and is more suitable for dynamic multiphase/multimode fermentation processes. | Congli Mei Yong Su Guohai Liu Yuhan Ding Zhiling Liao | 2017 | Chinese Journal of Chemical Engineering2017,25,1: | 8 |
| 7 | A Review of Technical Advances,Barriers,and Solutions in the Power to Hydrogen(P2H)Roadmap显示文摘Power to hydrogen(P2H)provides a promising solution to the geographic mismatch between sources of renewable energy and the market,due to its technological maturity,flexibility,and the availability of technical and economic data from a range of active demonstration projects.In this review,we aim to provide an overview of the status of P2H,analyze its technical barriers and solutions,and propose potential opportunities for future research and industrial demonstrations.We specifically focus on the transport of hydrogen via natural gas pipeline networks and end-user purification.Strong evidence shows that an addition of about 10%hydrogen into natural gas pipelines has negligible effects on the pipelines and utilization appliances,and may therefore extend the asset value of the pipelines after natural gas is depleted.To obtain pure hydrogen from hydrogen-enriched natural gas(HENG)mixtures,end-user separation is inevitable,and can be achieved through membranes,adsorption,and other promising separation technologies.However,novel materials with high selectivity and capacity will be the key to the development of industrial processes,and an integrated membrane-adsorption process may be considered in order to produce high-purity hydrogen from HENG.It is also worth investigating the feasibility of electrochemical separation(hydrogen pumping)at a large scale and its energy analysis.Cryogenics may only be feasible when liquefied natural gas(LNG)is one of the major products.A range of other technological and operational barriers and opportunities,such as water availability,byproduct(oxygen)utilization,and environmental impacts,are also discussed.This review will advance readers’understanding of P2H and foster the development of the hydrogen economy. | Guoping Hu Chao Chen Hiep Thuan Lu Yue Wu Congmin Liu Lefu Tao Yuhan Men Guangli He Kevin Gang Li | 2020 | Engineering2020,6,12: | 7 |
| 8 | Adjuvant treatment for triple-negative breast cancer: a retrospective study of immunotherapy with autologous cytokine-induced killer cells in 294 patients显示文摘Objective: To examine the efficacy and safety of a sequential combination of chemotherapy and autologous cytokine-induced killer(CIK) cell treatment in triple-negative breast cancer(TNBC) patients.Methods: A total of 294 post-surgery TNBC patients participated in the research from January 1, 2009 to January 1, 2015. After adjuvant chemotherapy, autologous CIK cells were introduced in 147 cases(CIK group), while adjuvant chemotherapy alone was used to treat the remaining 147 cases(control group). The major endpoints of the investigation were the disease-free survival(DFS) and overall survival(OS). Additionally, the side effects of the treatment were evaluated.Results: In the CIK group, the DFS and OS intervals of the patients were significantly longer than those of the control group(DFS:P = 0.047;OS: P = 0.007). The multivariate analysis demonstrated that the TNM(tumor-node-metastasis) stage and adjuvant CIK treatment were independent prognostic factors for both DFS [hazard ratio(HR)= 0.520, 95% confidence interval(CI):0.271-0.998, P = 0.049;HR = 1.449, 95% CI:1.118-1.877, P = 0.005, respectively] and OS(HR=0.414, 95% CI:0.190-0.903, P = 0.027;HR= 1.581, 95% CI:1.204-2.077, P = 0.001, respectively) in patients with TNBC. Additionally, longer DFS and OS intervals were associated with increased number of CIK treatment cycles(DFS: P = 0.020;OS: P = 0.040). The majority of the patients who benefitted from CIK cell therapy were relatively early-stage TNBC patients.Conclusion: Chemotherapy in combination with adjuvant CIK could be used to lower the relapse and metastasis rate, thus effectively extending the survival time of TNBC patients, especially those at early stages. | Yuhan Zhang Shuaibing Wang Beibei Yang Su Lu Yiyi Du Hong Liu | 2019 | Cancer Biology & Medicine2019,16,2: | 6 |

| 10 | In situ monitoring of atmospheric nitrous acid based on multi-pumping flow system and liquid waveguide capillary cell显示文摘In the last four decades, various techniques including spectroscopic, wet chemical and mass spectrometric methods, have been developed and applied for the detection of ambient nitrous acid(HONO). We developed a HONO detection system based on long path photometry which consists of three independent modules i.e., sampling module, fluid propulsion module and detection module. In the propulsion module, solenoid pumps are applied. With solenoid pumps the pulsed flow can be computer controlled both in terms of pump stroke volume and pulse frequency, which enables the attainment of a very stable flow rate. In the detection module, a customized Liquid Waveguide Capillary Cell(LWCC) is used. The customized LWCC pre-sets the optical fiber in-coupling with the liquid wave guide, providing the option of fast startup and easy maintenance of the absorption photometry. In summer 2014, our system was deployed in a comprehensive campaign at a rural site in the North China Plain. More than one month of high quality HONO data spanning from the limit of detection to 5 ppb were collected. Intercomparison of our system with another established system from Forschungszentrum Juelich is presented and discussed. In conclusion, our instrument achieved a detection limit of 10 ppt V within2 min and a measurement uncertainty of 7%, which is well suited for investigation of the HONO budget from urban to rural conditions in China. | Yuhan Liu Keding Lu Huabin Dong Xin Li Peng Cheng Qi Zou Yusheng Wu Xingang Liu Yuanhang Zhang | 2016 | Journal of Environmental Sciences2016,28,5: | 4 |
| 11 | Efficacy of Traditional Chinese Medicine in patients with acute myocardial infarction suffering from diabetes mellitus显示文摘OBJECTIVE: To investigate the 'real world' effectiveness of Traditional Chinese Medicine(TCM) in patients with acute myocardial infarction suffering from diabetes mellitus(AMI+DM patients).METHODS: This was a retrospective cohort study.During hospitalization, the 'exposure group' was defined as patients who had a TCM injection for ≥ 7 d.During follow-up, the definition of the exposure group was application of a Chinese patent medicine or decoction of Chinese medicine for ≥ 28 d.General information(age, sex, contact details), TCM use and endpoint events of AMI+DM patients during hospitalization and follow-up were collected.The correlation between TCM and the end-point events of AMI + DM patients was analyzed using a multiple logistic regression method.RESULTS: A total of 479 AMI + DM patients were enrolled and 345 cases were followed up. During hospitalization, TCM, age, hypertension and use of an angiotensin-converting enzyme inhibitor(ACEI)or angiotensin receptor blocker(ARB) were associated with cardiac death. During follow-up, TCM was associated with cardiac death. TCM was a relevant factor for a composite endpoint of re-infarction and stroke. TCM, anti-thrombotic therapy and lipid-lowering therapy were related to acute heart failure. TCM, anti-thrombotic therapy, anti-MI therapy and ACEI/ARB use exhibited a strong correlation with re-hospitalization due to cardiovascular disease.CONCLUSION: TCM reduced the prevalence of cardiac death during hospitalization, and cardiac death, a composite endpoint of re-infarction and stroke, acute heart failure and re-hospitalization due to cardiovascular disease during follow-up. | Dai Guohua Gao Wulin Bi Dongxue Liu Chunhua Liu Yuhan Wang Ning Zhao Chen | 2018 | Journal of Traditional Chinese Medicine2018,38,3: | 4 |
| 12 | Morphology and magnetic properties of α-Fe_2O_3 particles prepared by octadecylamine-assisted hydrothermal method显示文摘α-Fe2O3 particles with various morphologies,including micro-doublesphere,tetrakaidecahedron and nanoparticles-aggregated micro-ellipsoid,were successfully synthesized via an octadecylamine-assisted hydrothermal method.The products were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM)and high-resolution transmission electron microscopy(HRTEM).The results indicate that the presence of octadecylamine played a crucial role in morphology evolution by selective crystal adsorption.The protonated octadecylamine increased the pH value that accelerated nucleation,and the long alkyl groups of octadecylamine acted as an adsorption inhibitor to retard the growth of nanoparticles. The as-prepared α-Fe2O3 particles exhibited higher remanent magnetization and coercivity than other α-Fe2O3 particles of similar size.These properties should be attributed to the superstructure and the shape anisotropy of the synthesized particles. | Zhong Liu Baoliang Lv Dong Wu Yuhan Sun | 2012 | Particuology2012,10,4: | 3 |
| 13 | Nuclear UHRF1 is a gate-keeper of cellular AMPK activity and function显示文摘The AMP-activated protein kinase(AMPK)is a central regulator of energy homeostasis.Although much has been learned on how low energy status and glucose starvation activate AMPK,how AMPK activity is properly controlled in vivo is still poorly understood.Here we report that UHRF1,an epigenetic regulator highly expressed in proliferating and cancer cells,interacts with AMPK and serves to suppress AMPK activity under both basal and stressed conditions.As a nuclear protein,UHRF1 promotes AMPK nuclear retention and strongly suppresses nuclear AMPK activity toward substrates H2B and EZH2.Importantly,we demonstrate that UHRF1 also robustly inhibits AMPK activity in the cytoplasm compartment,most likely as a consequence of AMPK nucleocytoplasmic shuttling.Mechanistically,we found that UHRF1 has no obvious effect on AMPK activation by upstream kinases LKB1 and CAMKK2 but inhibits AMPK activity by acting as a bridging factor targeting phosphatase PP2A to dephosphorylate AMPK.Hepatic overexpression of UHRF1 showed profound effects on glucose and lipid metabolism in wild-type mice but not in those with the liver-specific knockout of AMPKα1/α2,whereas knockdown of UHRF1 in adipose tissue led to AMPK activation and reduced sizes of adipocytes and lipogenic activity,highlighting the physiological significance of this regulation in glucose and lipid metabolism.Thus,our study identifies UHRF1 as a novel AMPK gate-keeper with critical roles in cellular metabolism. | Xiang Xu Guangjin Ding Caizhi Liu Yuhan Ding Xiaoxin Chen Xiaoli Huang Chen-Song Zhang Shanxin Lu Yunpeng Zhang Yuanyong Huang Zhaosu Chen Wei Wei Lujian Liao Shu-Hai Lin Jingya Li Wei Liu Jiwen Li Sheng-Cai Lin Xinran Ma Jiemin Wong | 2022 | Cell Research2022,32,1: | 3 |
| 14 | ABM-based emergency evacuation modelling during urban pluvial floods:A“7.20”pluvial flood event study in Zhengzhou,Henan Province显示文摘Increasing urban pluvial flood disasters due to climate change and rapid urbanisation have been a great challenge worldwide.Timely and effective emergency evacuation is important for reducing casualties and losses.This has become a bottleneck for emergency management.This study aimed to develop a commonly used Agent-Based Mode(ABM)for pluvial flood emergency evacuation at the city scale,exploring the cascading impacts of pluvial flooding on human behaviour and emergency evacuation.The July 2021 pluvial flood event in Zhengzhou,Henan Province,claiming 380 lives and 40.9 billion yuan in direct losses,was selected as this case study.A raster-based hydraulic model(ECNU Flood-Urban)was used to predict flood inundation(extent and depth)during an event in Zhengzhou’s centre.Moreover,a comparative analysis of emergency evacuations was conducted before and after the pluvial flood event.The results showed that crowd behaviour plays an important role in an emergency evacuation,and extensive flooding leads to an 11-83%reduction in the number of evacuees.This study highlights the importance of risk education and contingency plans in emergency response.The ABM model developed in this study is proven to be effective and practical and will provide support for decision-making in urban flood emergency management. | Yuhan YANG Jie YIN Dandan WANG Yufan LIU Yi LU Weiguo ZHANG Shiyuan XU | 2023 | Science China Earth Sciences2023,66,2: | 2 |
| 15 | Magnetic and electrochemical behavior of rhombohedral α-Fe_2O_3 nanoparticles with (104) dominant facets显示文摘Uniform rhombohedral α-Fe_2O_3 nanoparticles,~60nm in size,were synthesized via a triphenylphosphine-assisted hydrothermal method.Scanning electron micrograph(SEM) and transmission electron micrograph(TEM) analyses showed that the as-synthesized rhombohedral nanoparticles were enclosed by six(104) planes.The concentration of triphenylphosphine played an important role in morphological evolution of the α-Fe_2O_3 nanoparticles.The as-prepared rhombohedral nanoparticles possessed remanent magnetization M_r of 2.6×10^(-3) emu/g and coercivity H_C of 2.05 Oe,both lower than those of other α-Fe_2O_3 particles with similar size,indicating their potential applications as superparamagnetic precursor materials.Furthermore,these rhombohedral α-Fe_2O_3 nanoparticles exhibited good sensor capability toward H_2O_2 with a linear response in the concentration range of 2-20 mM. | Zhong Liu Baoliang Lv Dong Wu Yuhan Sun Yao Xu | 2013 | Particuology2013,11,3: | 2 |
| 16 | Effects of miR-101-3p on goat granulosa cells in vitro and ovarian development in vivo via STC1显示文摘Background:MiRNAs act as pivotal post-transcriptional gene mediators in the regulation of diverse biological processes,including proliferation,development and apoptosis.Our previous study has showed that miR-101-3p is differentially expressed in dairy goat ovaries compared single with multiple litters.The objective of this research was to explore the potential function and molecular mechanism of miR-101-3p via its target STC1 in goat ovarian growth and development.Results:cDNA libraries were constructed using goat granulosa cells transfected with miR-101-3p mimics and negative control by RNA-sequencing.In total,142 differentially expressed unigenes(DEGs)were detected between two libraries,including 78 down-regulated and 64 up-regulated genes.GO and KEGG enrichment analysis showed the potential impacts of DEGs on ovarian development.STC1 was singled out from DEGs for further research owing to it regulates reproductive-related processes.In vitro,bioinformatics analysis and 3′-UTR assays confirmed that STC1 was a target of miR-101-3p.ELISA was performed to detect the estrogen(E2)and progesterone(P4)levels.CCK8,EdU and flow cytometry assays were performed to detect the proliferation and apoptosis of granulosa cells.Results showed that miR-101-3p regulated STAR,CYP19A1,CYP11A1 and 3β-HSD steroid hormone synthesis-associated genes by STC1 depletion,thus promoted E2 and P4 secretions.MiR-101-3p also affected the key protein PI3K,PTEN,AKT and mTOR in PI3K-AKT pathway by STC1,thereby suppressing proliferation and promoting apoptosis of granulosa cells.In vivo,the distribution and expression levels of miR-101-3p in mouse ovaries were determined through fluorescence in situ hybridisation(FISH).Immunohistochemistry results showed that STC1 expression was suppressed in mouse ovaries in miR-101-3p-agonist and siRNA-STC1 groups.Small and stunted ovarian fragments,decreased numbers of follicles at diverse stages were observed using Hematoxylin-eosin(HE)staining,thereby showing unusual ovarian development after miR-101-3p overexpression or STC1 depletion.Inhibition of miR-101-3p manifested opposite results.Conclusions:Taken together,our results demonstrated a regulatory mechanism of miR-101-3p via STC1 in goat granulosa cells,and offered the first in vivo example of miR-101-3p and STC1 functions required for ovarian development. | Xiaopeng An Haidong Ma Yuhan Liu Fu Li Yuxuan Song Guang Li Yueyu Bai Binyun Cao | 2021 | Journal of Animal Science and Biotechnology2021,12,2: | 2 |

| 18 | The novel ER stress inducer Sec C triggers apoptosis by sulfating ER cysteine residues and degrading YAP via ER stress in pancreatic cancer cells显示文摘Pancreatic adenocarcinoma(PAAD) is one of the most lethal malignancies. Although gemcitabine(GEM) is a standard treatment for PAAD, resistance limits its application and therapy. Secoemestrin C(Sec C) is a natural compound from the endophytic fungus Emericella, and its anticancer activity has not been investigated since it was isolated. Our research is the first to indicate that Sec C is a broad-spectrum anticancer agent and could exhibit potently similar anticancer activity both in GEM-resistant and GEM-sensitive PAAD cells. Interestingly, Sec C exerted a rapid growth-inhibiting effect(80% death at 6 h), which might be beneficial for patients who need rapid tumor shrinkage before surgery. Liquid chromatography/mass spectrometry and N-acetyl-L-cysteine(NAC) reverse assays show that Sec C sulfates cysteines to disrupt disulfide-bonds formation in endoplasmic reticulum(ER) proteins to cause protein misfolding, leading to ER stress and disorder of lipid biosynthesis. Microarray data and subsequent assays show that ER stress-mediated ER-associated degradation(ERAD) ubiquitinates anddownregulates YAP to enhance ER stress via destruction complex(YAP-Axin-GSK-βTr CP), which also elucidates a unique degrading style for YAP. Potent anticancer activity in GEM-resistant cells and low toxicity make Sec C a promising anti-PAAD candidate. | Junxia Wang Minghua Chen Mengyan Wang Wenxia Zhao Conghui Zhang Xiujun Liu Meilian Cai Yuhan Qiu Tianshu Zhang Huimin Zhou Wuli Zhao Shuyi Si Rongguang Shao | 2022 | Acta Pharmaceutica Sinica B2022,12,1: | 2 |

| 20 | Graphitic carbon nitride-based photocatalysts in the applications of environmental catalysis显示文摘Semiconductor photocatalytic technology has shown great prospects in converting solar energy into chemical energy to mitigate energy crisis and solve environmental pollution problems.The key issue is the development of high-efficiency photocatalysts.Various strategies in the state-of-the-art advancements,such as heterostructure construction,heteroatom doping,metal/single atom loading,and defect engineering,have been presented for the graphitic carbon nitride(g-C3N4)-based nanocomposite catalysts to design their surface chemical environments and internal electronic structures to make them more suitable for different photocatalytic applications.In this review,nanoarchitecture design,synthesis methods,photochemical properties,potential photocatalytic applications,and related reaction mechanisms of the modified high-efficiency carbon nitride-based photocatalysts were briefly summarized.The superior photocatalytic performance was identified to be associated with the enhanced visible-light response,fast photoinduced electron-hole separation,efficient charge migration,and increased unsaturated active sites.Moreover,the further advance of the visible-light harvesting and solar-to-energy conversions are proposed. | Hongxia Lin JinmoWu Fan Zhou Xiaolong Zhao Pengfei Lu Guanghui Sun Yuhan Song Yayun Li Xiaoyong Liu Hongxing Dai | 2023 | Journal of Environmental Sciences2023,,2: | 2 |
