| 1 | Discovery and identification of EIF2AK2 as a direct key target of berberine for anti-inflammatory effects显示文摘Using chemoproteomic techniques,we first identified EIF2AK2,eEF1A1,PRDX3 and VPS4B as direct targets of berberine(BBR)for its synergistically anti-inflammatory effects.Of them,BBR has the strongest affinity with EIF2AK2 via two ionic bonds,and regulates several key inflammatory pathways through EIF2AK2,indicating the dominant role of EIF2AK2.Also,BBR could subtly inhibit the dimerization of EIF2AK2,rather than its enzyme activity,to selectively modulate its downstream pathways including JNK,NF-κB,AKT and NLRP3,with an advantage of good safety profile.In EIF2AK2 gene knockdown mice,the inhibitory IL-1β,IL-6,IL-18 and TNF-a secretion of BBR was obviously attenuated,confirming an EIF2AK2-dependent anti-inflammatory efficacy.The results highlight the BBR's network mechanism on anti-inflammatory effects in which EIF2AK2 is a key target,and inhibition of EIF2AK2 dimerization has a potential to be a therapeutic strategy against inflammationrelated disorders. | Wei Wei Qingxuan Zeng Yan Wang Xixi Guo Tianyun Fan Yinghong Li Hongbin Deng Liping Zhao Xintong Zhang Yonghua Liu Yulong Shi Jingyang Zhu Xican Ma Yanxiang Wang Jiandong Jiang Danqing Song | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 2 |

| 3 | Inhibition of the negative effect of high glucose on osteogenic differentiation of bone marrow stromal cells by silicon ions from calcium silicate bioceramics显示文摘Human bone marrow stem cells(hBMSCs)are exploited for miscellaneous applications in bone tissue engineering where they are mainly used as seed cells.However,high glucose(HG)environment has negative impacts on the proliferation and osteogenic differentiation of hBMSCs,thus reducing the bone formation in diabetic patients.In our former research works,we discovered that silicon(Si)ions extracted from silicate-based bioceramics are able to stimulate the proliferation and osteogenic differentiation of hBMSCs under normal culture condition.This study aimed to investigate if Si ions could prevent HG-induced inhibition of proliferation and osteogenesis of hBMSCs.We found that 2.59ppm concentration of Si ions promoted the proliferation of hBMSCs under HG condition.The results from alkaline phosphatase(ALP)activity assay,Alizarin red S staining and quantitative real-time PCR analysis of osteogenic genes(BMP2,RUNX2,ALP,COL1 and OCN)demonstrated that the 15.92ppm concentration of Si ions prevented HG-induced inhibition of the osteogenic differentiation of hBMSCs.Moreover,application of Si ions reduced the level of reactive oxygen species in HG-treated hBMSCs.In HG-treated hBMSCs following 15.92ppm Si ions treatment,activation of BMP2/SMAD signaling pathway was detected,as indicated by the increased expression of BMP2 receptors and its downstream genes such as SMAD1,SMAD4 and SMAD5.Taken together,we provide evidence that the specific concentration of Si ions compensated HG-induced inhibition of proliferation and osteogenic differentiation of hBMSCs through antioxidant effect and modulation of BMP2/SMAD pathway.The results suggest that silicate-based bioceramics might be good scaffold biomaterials for bone engineering applications in diabetes patients. | Xixi Dong Xiaoya Wang Min Xing Cancan Zhao Bin Guo Junkai Cao Jiang Chang | 2020 | Regenerative Biomaterials2020，7，1： | 1 |
| 4 | Stacking monolayers at will:A scalable device optimization strategy for two-dimensional semiconductors显示文摘In comparison to monolayer(1L),multilayer(ML)two-dimensional(2D)semiconducting transition metal dichalcogenides(TMDs)exhibit more application potential for electronic and optoelectronic devices due to their improved current carrying capability,higher mobility,and broader spectral response.However,the investigation of devices based on wafer-scale ML-TMDs is still restricted by the synthesis of uniform and high-quality ML films.In this work,we propose a strategy of stacking MoS_(2) monolayers via a vacuum transfer method,by which one could obtain wafer-scale high-quality MoS_(2) films with the desired number of layers at will.The optical characteristics of these stacked ML-MoS_(2) films(>2L)indicate a weak interlayer coupling.The stacked MLMoS_(2) phototransistors show improved optoelectrical performances and a broader spectral response(approximately 300-1,000 nm)than that of 1L-MoS_(2).Additionally,the dual-gate ML-MoS_(2) transistors enable enhanced electrostatic control over the stacked ML-MoS_(2) channel,and the 3L and 4L thicknesses exhibit the optimal device performances according to the turning point of the current on/off ratio and the subthreshold swing. | Xiaojiao Guo Honglei Chen Jihong Bian Fuyou Liao Jingyi Ma Simeng Zhang Xinzhi Zhang Junqiang Zhu Chen Luo Zijian Zhang Lingyi Zong Yin Xia Chuming Sheng Zihan Xu Saifei Gou Xinyu Wang Peng Gong Liwei Liu Xixi Jiang Zhenghua An Chunxiao Cong Zhijun Qiu Xing Wu Peng Zhou Xinyu Chen Ling Tong Wenzhong Bao | 2022 | Nano Research2022，15，7： | 0 |

| 6 | Lipid droplets as endogenous intracellular microlenses显示文摘Using a single biological element as a photonic component with well-defined features has become a new intriguing paradigm in biophotonics.Here we show that endogenous lipid droplets in the mature adipose cells can behave as fully biocompatible microlenses to strengthen the ability of microscopic imaging as well as detecting intra-and extracellular signals.By the assistance of biolenses made of the lipid droplets,enhanced fluorescence imaging of cytoskeleton,lysosomes,and adenoviruses has been achieved.At the same time,we demonstrated that the required excitation power can be reduced by up to 73%.The lipidic microlenses are finely manipulated by optical tweezers in order to address targets and perform their real-time imaging inside the cells.An efficient detecting of fluorescence signal of cancer cells in extracellular fluid was accomplished due to the focusing effect of incident light by the lipid droplets.The lipid droplets acting as endogenous intracellular microlenses open the intriguing route for a multifunctional biocompatible optics tool for biosensing,endoscopic imaging,and single-cell diagnosis. | Xixi Chen Tianli Wu Zhiyong Gong Jinghui Guo Xiaoshuai Liu Yao Zhang Yuchao Li Pietro Ferraro Baojun Li | 2021 | Light(Science & Applications)2021，10，12： | 0 |
| 7 | Greenhouse gas emissions from Daihai Lake,China:Should eutrophication and salinity promote carbon emission dynamics?显示文摘Greenhouse gases(GHGs)emitted or absorbed by lakes are an important component of the global carbon cycle.However,few studies have focused on the GHG dynamics of eutrophic saline lakes,thus preventing a comprehensive understanding of the carbon cycle.Here,we conducted four sampling analyses using a floating chamber in Daihai Lake,a eutrophication saline lake in Inner Mongolia Autonomous Region,China,to explore its carbon dioxide(CO_(2))and methane(CH_(4))emissions.The mean CO_(2)emission flux(FCO_(2))and CH_(4)emission flux(FCH_(4))were 17.54±14.54 mmol/m^(2)/day and 0.50±0.50 mmol/m^(2)/day,respectively.The results indicated that Daihai Lake was a source of CO_(2)and CH_(4),and GHG emissions exhibited temporal variability.The mean CO_(2)partial pressure(p CO_(2))and CH_(4)partial pressure(p CH_(4))were 561.35±109.59μatm and 17.02±13.45μatm,which were supersaturated relative to the atmosphere.The regression and correlation analysis showed that the main influencing factors of p CO_(2)were wind speed,dissolved oxygen(DO),total nitrogen(TN)and Chlorophyll a(Chl.a),whereas the main influencing factors of p CH_(4)were water temperature(WT),Chl.a,nitrate nitrogen(NO_(3)^(-)-N),TN,dissolved organic carbon(DOC)and water depth.Salinity regulated carbon mineralization and organic matter decomposition,and it was an important influencing factor of p CO_(2)and p CH_(4).Additionally,the trophic level index(TLI)significantly increased p CH_(4).Our study elucidated that salinity and eutrophication play an important role in the dynamic changes of GHG emissions.However,research on eutrophic saline lakes needs to be strengthened. | Xiangwei Li Ruihong Yu Jun Wang Heyang Sun Xinyu Liu Xiaohui Ren Shuai Zhuang Zhiwei Guo Xixi Lu | 2024 | Journal of Environmental Sciences2024，，1： | 0 |
