| 1 | Neuroprotective effects of ginsenoside Rb1 on hippocampal neuronal injury and neurite outgrowth显示文摘Ginsenoside Rb1 has been reported to exert anti-aging and anti-neurodegenerative effects. In the present study, we investigate whether ginsenoside Rb1 is involved in neurite outgrowth and neuroprotection against damage induced by amyloid beta(25–35) in cultured hippocampal neurons, and explore the underlying mechanisms. Ginsenoside Rb1 significantly increased neurite outgrowth in hippocampal neurons, and increased the expression of phosphorylated-Akt and phosphorylated extracellular signal-regulated kinase 1/2. These effects were abrogated by API-2 and PD98059, inhibitors of the signaling proteins Akt and MEK. Additionally, cultured hippocampal neurons were exposed to amyloid beta(25–35) for 30 minutes; ginsenoside Rb1 prevented apoptosis induced by amyloid beta(25–35), and this effect was blocked by API-2 and PD98059. Furthermore, ginsenoside Rb1 significantly reversed the reduction in phosphorylated-Akt and phosphorylated extracellular signal-regulated kinase 1/2 levels induced by amyloid beta(25–35), and API-2 neutralized the effect of ginsenoside Rb1. The present results indicate that ginsenoside Rb1 enhances neurite outgrowth and protects against neurotoxicity induced by amyloid beta(25–35) via a mechanism involving Akt and extracellular signal-regulated kinase 1/2 signaling. | Juan Liu Jing He Liang Huang Ling Dou Shuang Wu Qionglan Yuan | 2014 | Neural Regeneration Research2014,9,9: | 15 |
| 2 | Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits. | Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang | 2022 | National Science Review2022,9,1: | 13 |

| 4 | Graphitic carbon nitride (g-C3N4)-based nanosized heteroarrays: Promising materials for photoelectrochemical water splitting显示文摘Photoelectrochemical(PEC)water splitting is recognized as a sustainable strategy for hydrogen generation due to its abundant hydrogen source,utilization of inexhaustible solar energy,high-purity product,and environment-friendly process.To actualize a practical PEC water splitting,it is paramount to develop efficient,stable,safe,and low-cost photoelectrode materials.Recently,graphitic carbon nitride(g-C3N4)has aroused a great interest in the new generation photoelectrode materials because of its unique features,such as suitable band structure for water splitting,a certain range of visible light absorption,nontoxicity,and good stability.Some inherent defects of g-C3N4,however,seriously impair further improvement on PEC performance,including low electronic conductivity,high recombination rate of photogenerated charges,and limited visible light absorption at long wavelength range.Construction of g-C3N4-based nanosized heteroarrays as photoelectrodes has been regarded as a promising strategy to circumvent these inherent limitations and achieve the high-performance PEC water splitting due to the accelerated exciton separation and the reduced combination of photogenerated electrons/holes.Herein,we summarize in detail the latest progress of g-C3N4-based nanosized heteroarrays in PEC water-splitting photoelectrodes.Firstly,the unique advantages of this type of photoelectrodes,including the highly ordered nanoarray architectures and the heterojunctions,are highlighted.Then,different g-C3N4-based nanosized heteroarrays are comprehensively discussed,in terms of their fabrication methods,PEC capacities,and mechanisms,etc.To conclude,the key challenges and possible solutions for future development on g-C3N4-based nanosized heteroarray photoelectrodes are discussed. | Liqun Wang Wenping Si Yueyu Tong Feng Hou Daniele Pergolesi Jungang Hou Thomas Lippert Shi Xue Dou Ji Liang | 2020 | Carbon Energy2020,2,2: | 10 |
| 5 | Ginsenoside Rg1 protects against neurodegeneration by inducing neurite outgrowth in cultured hippocampal neurons显示文摘Ginsenoside Rg1(Rg1) has anti-aging and anti-neurodegenerative effects. However, the mechanisms underlying these actions remain unclear. The aim of the present study was to determine whether Rg1 affects hippocampal survival and neurite outgrowth in vitro after exposure to amyloid-beta peptide fragment 25–35(Aβ_(25–35)), and to explore whether the extracellular signal-regulated kinase(ERK) and Akt signaling pathways are involved in these biological processes. We cultured hippocampal neurons from newborn rats for 24 hours, then added Rg1 to the medium for another 24 hours, with or without pharmacological inhibitors of the mitogen-activated protein kinase(MAPK) family or Akt signaling pathways for a further 24 hours. We then immunostained the neurons for growth associated protein-43, and measured neurite length. In a separate experiment, we exposed cultured hippocampal neurons to Aβ_(25–35) for 30 minutes, before adding Rg1 for 48 hours, with or without Akt or MAPK inhibitors, and assessed neuronal survival using Hoechst 33258 staining, and phosphorylation of ERK1/2 and Akt by western blot analysis. Rg1 induced neurite outgrowth, and this effect was blocked by API-2(Akt inhibitor) and PD98059(MAPK/ERK kinase inhibitor), but not by SP600125 or SB203580(inhibitors of c-Jun N-terminal kinase and p38 MAPK, respectively). Consistent with this effect, Rg1 upregulated the phosphorylation of Akt and ERK1/2; these effects were reversed by API-2 and PD98059, respectively. In addition, Rg1 significantly reversed Aβ_(25–35)-induced apoptosis; this effect was blocked by API-2 and PD98059, but not by SP600125 or SB203580. Finally, Rg1 significantly reversed the Aβ_(25–35)-induced decrease in Akt and ERK1/2 phosphorylation, but API-2 prevented this reversal. Our results indicate that Rg1 enhances neurite outgrowth and protects against Aβ_(25–35)-induced damage, and that its mechanism may involve the activation of Akt and ERK1/2 signaling. | Liang Huang Li-feng Liu Juan Liu Ling Dou Ge-ying Wang Xiao-qing Liu Qiong-lan Yuan | 2016 | Neural Regeneration Research2016,11,2: | 9 |
| 6 | Osteoclast-derived apoptotic bodies couple bone resorption and formation in bone remodeling显示文摘Bone remodeling is precisely coordinated by bone resorption and formation.Apoptotic osteoclasts generate large amounts of apoptotic bodies(ABs)marking the end of the bone resorption phase,whereas the functions of osteoclast-derived ABs remain largely unknown.Here,we identified the molecular profile of ABs derived from osteoclasts at distinct differentiation stages and investigated their corresponding functions.ABs were isolated from apoptotic bone marrow macrophages,preosteoclasts,and mature osteoclasts induced by staurosporine.Proteomic signature analysis with liquid chromatography-tandem mass spectrometry suggested marked protein cargo differences among the different ABs.Further bioinformatic analysis showed that the proteomic signatures of the ABs were highly similar to those of their parental cells.Functionally,pOC-ABs induced endothelial progenitor cell differentiation and increased CD31hiEmcnhi endothelial cell formation in a murine bone defect model via their PDGF-BB cargo.mOC-ABs induced osteogenic differentiation of mesenchymal stem cells and facilitated osteogenesis via RANKL reverse signaling.In summary,we mapped the detailed proteomic landscapes of ABs derived from osteoclasts and showed that their potential biological roles are important in coupling bone formation with resorption during bone remodeling. | Qinyu Ma Mengmeng Liang Yutong Wu Fei Luo Zaisong Ma Shiwu Dong Jianzhong Xu Ce Dou | 2021 | Bone Research2021,9,1: | 8 |

| 9 | The expression and binding properties of the rice WRKY68 protein in the Xa21-mediated resistance response to Xanthomonas oryzae pv. Oryzae显示文摘Plant WRKY transcription factors are involved in various physiological processes, including biotic and abiotic stress responses, as well as developmental processes. In this study, the expression patterns of the WRKY68 protein during interactions between rice 4021 containing the bacterial blight resistance gene Xa21 and Xanthomonas oryzae pv. oryzae(Xoo) were investigated. A possible modified form of the WRKY68 protein appeared in the Xa21-mediated disease resistance response, and its expression levels were similar in compatible and incompatible responses, but differed significantly from that of the mock control treatment, suggesting that WRKY68 may be involved in the bacterial blight response in rice. To further understand WRKY68's roles in the resistance signaling pathway, WRKY68 recombinant protein was expressed in Escherichia coli and a microscale thermophoresis analysis was performed to investigate the interactions between WRKY68 and cis-elements in crucial pathogenesis-related(PR) genes. The results showed that the WRKY68 protein binds to W-boxes in the PR1 b promoter region, with an apparent dissociation constant of 25 nmol L–1, while the binding between WRKY68 and PR10 a was W-box independent. The results suggested that a possible modified form of the WRKY68 protein was induced during the interaction between rice and Xoo, which then regulated the activity of the downstream PR genes by binding with the W-boxes in the PR1 b gene's promoter region. Moreover, the constitutive transcription of the WRKY68 gene in dozens of rice tissues and the expression of the WRKY68 protein in leaves during all growth stages suggests that WRKY68 plays important roles in rice during normal growth processes. | YANG Shuo ZHOU Liang MIAO Liu-yang SHI Jia-nan SUN Cai-qiang FAN Wei LAN Jin-ping CHEN Hao LIU Li-juan DOU Shi-juan LIU Guo-zhen LI Li-yun | 2016 | Journal of Integrative Agriculture2016,15,11: | 6 |
| 10 | Long non-coding RNA HOTAIRM1 promotes proliferation and inhibits apoptosis of glioma cells by regulating the miR-873-5p/ZEB2 axis显示文摘Background:Glioblastoma is one of the most common malignant brain tumors.Conventional clinical treatment of glioblastoma is not sufficient,and the molecular mechanism underlying the initiation and development of this disease remains unclear.Our study aimed to explore the expression and function of miR-873a-5p in glioblastoma and related molecular mechanism.Methods:We analyzed the most dysregulated microRNAs from the Gene Expression Omnibus(GEO)database and examined the expression of miR-873-5p in 20 glioblastoma tissues compared with ten normal brain tissues collected in the Zhejiang Tongde Hospital.We then overexpressed or inhibited miR-873-5p expression in U87 glioblastoma cell lines and analyzed the phenotype using the cell counting kit-8 assay,wound healing assay,and apoptosis.In addition,we predicted upstream and downstream genes of miR-873-5p in glioblastoma using bioinformatics analysis and tested our hypothesis in U87 cells using the luciferase reporter gene assay and Western blotting assay.The differences between two groups were analyzed by Student’s t test.The Kruskal-Wallis test was used for the comparison of multiple groups.A P<0.05 was considered to be significant.Results:The miR-873-5p was downregulated in glioblastoma tissues compared with that in normal brain tissues(normal vs.tumor,0.762±0.231 vs.0.378±0.114,t=4.540,P<0.01).Overexpression of miR-873-5p inhibited cell growth(t=6.095,P<0.01)and migration(t=3.142,P<0.01)and promoted cell apoptosis(t=4.861,P<0.01),while inhibition of miR-873-5p had the opposite effect.Mechanistically,the long non-coding RNA HOTAIRM1 was found to act as a sponge of miR-873-5p to activate ZEB2 expression in U87 cells.Conclusions:We uncovered a novel HOTAIRM1/miR-873-5p/ZEB2 axis in glioblastoma cells,providing new insight into glioblastoma progression and a theoretical basis for the treatment of glioblastoma. | Yi-Hai Lin Liang Guo Feng Yan Zhang-Qi Dou Qian Yu Gao Chen | 2020 | Chinese Medical Journal2020,,2: | 5 |

| 13 | Accelerated methane storage in clathrate hydrates using surfactantstabilized suspension with graphite nanoparticles显示文摘In this study,enhanced kinetics of methane hydrate formation in the sodium dodecyl sulfate(SDS)solution with different concentrations of suspended graphite nanoparticles(GNPs)were investigated at 6.1-9.0 MPa and 274.15 K.The GNPs with rough surfaces and excellent thermal conductivity not only provided a considerable number of microsites for hydrate nucleation but also facilitated the fast hydrate heat transfer in the suspension system.At a relatively low pressure of 6.1 MPa,the suspension with 0.4 wt%of GNPs exhibited the minimum induction time of 22 min and maximum methane uptake of 126.1 cm3·cm-3.However,the methane storage performances of the suspensions with higher and lower concentrations of GNPs were not satisfactory.At the applied pressure,the temperature increase arising from the hydrate heat in the suspension system with the optimized concentration(0.4 wt%)of GNPs was more significant than that in the traditional SDS solution.Furthermore,compared with those of the system without GNPs,enhanced hydration rate and storage capacity were achieved in the suspensions with GNPs,and the storage capacities were increased by 3.9%-17.0%.The promotion effect of GNPs on gas hydrate formation at low pressure is much more obvious than that at high pressure. | Liang Yang Xin Wang Daoping Liu Guomin Cui Binlin Dou Juan Wang Shuqing Hao | 2020 | Chinese Journal of Chemical Engineering2020,28,4: | 4 |
| 14 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022,65,12: | 4 |
| 15 | Effect of combined medicated thread moxibustion plus needle picking therapy of Zhuang nationality medicine on antioxidant levels in a rat model of sciatica显示文摘OBJECTIVE: To investigate the effect and underlying mechanisms of combined medicated thread moxibustion therapy plus needle picking therapy of Zhuang nationality medicine on antioxidant levels in a rat model of sciatica.METHODS: One hundred Wistar rats, of specific pathogen free level, were randomly divided into five groups: normal control group, model group,medicated thread moxibustion group, needle picking group, and combination group. Each group contained 20 rats. In the model, medicated thread moxibustion, needle picking, and combination groups,sciatica models were established through chronicconstriction injury of the sciatic nerve. After the model was established, the rats in the medicated thread moxibustion, needle picking, and combination groups were given the corresponding therapies for 21 days. The control and model groups received no treatment. Reactive oxygen species, superoxide dismutase, malondialdehyde, and total antioxidant capacity changes were determined.Nicotinamide adenine dinucleotide phosphate(NADPH) oxidase subunit NADPH oxidases 4(NOX4) m RNA expression and the morphology of cells were observed to detect apoptosis of gamma-aminobutyric acid ergic(GABAergic) neurons.RESULTS: Compared with control group, reactive oxygen species and malondialdehyde levels rose significantly in the model group(P < 0.01), while superoxide dismutase and total antioxidant capacity levels were lowered(P < 0.05). Compared with the model group, reactive oxygen species and malondialdehyde decreased in the needle picking group(P < 0.05), while superoxide dismutase levels were increased(P < 0.05); reactive oxygen species and malondialdehyde significantly decreased in the combination group(P < 0.01). In addition, the model group had higher NOX4 m RNA expression than that of the control group(P < 0.05), and the combination group had lower expression levels than that of the model group(P < 0.05). Apoptosis of GABAergic neurons was observed in the model group, and was attenuated after combined therapy.CONCLUSION: The medicated thread moxibustion therapy plus needle picking therapy of Zhuang nationality medicine can prevent oxidative damage in the rat model of sciatica via down-regulating NOX4 expression, improving antioxidant capacity, and in-hibiting the oxidative damage pathway of GABAergic neurons. | Tang Hanqing Zheng Jianyu Li Tianzi Li Keming Li Xiaohua Dou Xibin Huang Chunchuan Liang Ye | 2016 | Journal of Traditional Chinese Medicine2016,36,6: | 4 |
| 16 | Pt/WO_3/C nanocomposite with parallel WO_3 nanorods as cathode catalyst for proton exchange membrane fuel cells显示文摘Pt/WO3/C nanocomposites with parallel WO3 nanorods were synthesized and applied as the cathode catalyst for proton exchange membrane fuel cells(PEMFCs). Electrochemical results and single cell tests show that an enhanced activity for the oxygen reduction reaction(ORR) is obtained for the Pt/WO3/C catalyst compared with Pt/C. The higher catalytic activity might be ascribed to the improved Pt dispersion with smaller particle sizes. The Pt/WO3/C catalyst also exhibits a good electrochemical stability under potential cycling. Thus, the Pt/WO3/C catalyst can be used as a potential PEMFC cathode catalyst. | Meiling Dou Ming Hou Zhilin Li Feng Wang Dong Liang Zhigang Shao Baolian Yi | 2015 | Journal of Energy Chemistry2015,24,1: | 4 |
| 17 | H.sinensis mycelium inhibits epithelial–mesenchymal transition by inactivating the midkine pathway in pulmonary fibrosis显示文摘The medical fungus Hirsutella sinensis has been used as a Chinese folk health supplement because of its immunomodulatory properties.Our previous studies established the antifibrotic action of Hirsutella sinensis mycelium(HSM)in the lung.The epithelial–mesenchymal transition(EMT)is involved in the pathogenesis of idiopathic pulmonary fibrosis.The present study investigates the role of HSM in mediating EMT during the development of pulmonary fibrosis.HSM significantly inhibits bleomycin(BLM)-induced pulmonary fibrosis by blocking the EMT.In addition,the expression levels of midkine are increased in the lungs of the BLM-induced group.Further analysis of the results indicates that the mRNA level of midkine correlated positively with EMT.HSM markedly abrogates the transforming growth factorβ-induced EMT-like phenotype and behavior in vitro.The activation of midkine related signaling pathway is ameliorated following HSM treatment,whereas this extract also caused an effective attenuation of the induction of EMT(caused by midkine overexpression)in vitro.Results further confirm that oral medication of HSM disrupted the midkine pathway in vivo.Overall,findings suggest that the midkine pathway and the regulation of the EMT may be considered novel candidate therapeutic targets for the antifibrotic effects caused by HSM. | Li Lu Haiyan Zhu Hailin Wang Huaping Liang Yayi Hou Huan Dou | 2021 | Frontiers of Medicine2021,15,2: | 3 |
