3Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only.Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao 2019Cell Research2019,29,2:16

7Glucocorticoid receptor promotes the function of myeloid-derived suppressor cells by suppressing HIF1α-dependent glycolysis显示文摘Immunomodulatory signaling imposes tight regulations on metabolic programs within immune cells and consequentially determines immune response outcomes.Although the glucocorticoid receptor(GR)has been recently implicated in regulating the function of myeloid-derived suppressor cells(MDSCs),whether the dysregulation of GR in MDSCs is involved in immune-mediated hepatic diseases and how GR regulates the function of MDSCs in such a context remains unknown.Here,we revealed the dysregulation of GR expression in MDSCs during innate immunological hepatic injury(IMH)and found that GR regulates the function of MDSCs through modulating HIF1α-dependent glycolysis.Pharmacological modulation of GR by its agonist(dexamethasone,Dex)protects IMH mice against inflammatory injury.Mechanistically,GR signaling suppresses HIF1αand HIF1α-dependent glycolysis in MDSCs and thus promotes the immune suppressive activity of MDSCs.Our studies reveal a role of GR-HIF1αin regulating the metabolism and function of MDSCs and further implicate MDSC GR signaling as a potential therapeutic target in hepatic diseases that are driven by innate immune cell-mediated systemic inflammation.Yun Lu Huanrong Liu Yujing Bi Hui Yang Yan Li Jian Wang Zhengguo Zhang Yu Wang Chunxiao Li Anna Jia Linian Han Ying Hu Yong Zhao Ruoning Wang Guangwei Liu 2018Cellular & Molecular Immunology2018,15,6:4
8High-performance polarization-sensitive photodetector based on a few-layered PdSe2 nanosheet显示文摘The extraordinary optical and electronic properties of anisotropic two-dimensional materials,such as black phosphorus,ReS2,and GeSe,enable them a promising component of polarization-sensitive photodetectors.However,these applications are significantly limited by the challenges of air-stability,response time,and linearly dichroic ratio.Interestingly,palladium diselenide(PdSe2)with high air stability is an emerging material that has robust in-plane anisotropy induced by its asymmetric pentagonal lattice structure.We have successfully prepared a few-layer PdSe2 using micromechanical exfoliation,and here we demonstrate the strong linear dichroism behavior of PdSe2 by polarization-resolved absorption spectra measurements.Such unique linear dichroism,endows the PdSe2 photodetector powerful ability to detect polarized light.The photodetector based on 5L PdSe2,as tested with polarization-dependent photocurrent mapping,exhibited competitive capability to detect polarized light,achieving a significant photocurrent on/off ratio(>10^2),the quite fast response time(<11 ms)and robust linearly dichroic ratios(/max//min≈1.9 at 532 nm).These results are essential advance in the development of polarization-sensitive photodetector,a crucial step towards opening up a new avenue for the application of 2D optoelectronic devices.Jiahong Zhong Juan Yu Lingkai Cao Cheng Zeng Junnan Ding Chunxiao Cong Zongwen Liu Yanping Liu 2020Nano Research2020,13,6:4

10Systematic Full-Cycle Engineering Microbial Biofilms to Boost Electricity Production in Shewanella oneidensis显示文摘Electroactive biofilm plays a crucial rule in the electron transfer efficiency of microbial electrochemical systems(MES).However,the low ability to form biofilm and the low conductivity of the formed biofilm substantially limit the extracellular electron transfer rate of microbial cells to the electrode surfaces in MES.Feng Li Rui Tang Baocai Zhang Chunxiao Qiao Huan Yu Qijing Liu Junqi Zhang Liang Shi Hao Song 2023Research2023,,2:2
11The chromosome-level Stevia genome provides insights into steviol glycoside biosynthesis显示文摘Stevia(Stevia rebaudiana Bertoni)is well known for its very sweet steviol glycosides(SGs)consisting of a common tetracyclic diterpenoid steviol backbone and a variable glycone.Steviol glycosides are 150–300 times sweeter than sucrose and are used as natural zero-calorie sweeteners.However,the most promising compounds are biosynthesized in small amounts.Based on Illumina,PacBio,and Hi-C sequencing,we constructed a chromosome-level assembly of Stevia covering 1416 Mb with a contig N50 value of 616.85 kb and a scaffold N50 value of 106.55 Mb.More than four-fifths of the Stevia genome consisted of repetitive elements.We annotated 44,143 high-confidence protein-coding genes in the high-quality genome.Genome evolution analysis suggested that Stevia and sunflower diverged~29.4 million years ago(Mya),shortly after the whole-genome duplication(WGD)event(WGD-2,~32.1 Mya)that occurred in their common ancestor.Comparative genomic analysis revealed that the expanded genes in Stevia were mainly enriched for biosynthesis of specialized metabolites,especially biosynthesis of terpenoid backbones,and for further oxidation and glycosylation of these compounds.We further identified all candidate genes involved in SG biosynthesis.Collectively,our current findings on the Stevia reference genome will be very helpful for dissecting the evolutionary history of Stevia and for discovering novel genes contributing to SG biosynthesis and other important agronomic traits in future breeding programs.Xiaoyang Xu Haiyan Yuan Xiaqing Yu Suzhen Huang Yuming Sun Ting Zhang Qingquan Liu Haiying Tong Yongxia Zhang Yinjie Wang Chunxiao Liu Lei Wu Menglan Hou Yongheng Yang 2021Horticulture Research2021,8,1:2

15Unveiling the origin of anomalous low-frequency Raman mode in CVD-grown monolayer WS_(2)显示文摘Substrates provide the necessary support for scientific explorations of numerous promising features and exciting potential applications in two-dimensional (2D) transition metal dichalcogenides (TMDs). To utilize substrate engineering to alter the properties of 2D TMDs and avoid introducing unwanted adverse effects, various experimental techniques, such as high-frequency Raman spectroscopy, have been used to understand the interactions between 2D TMDs and substrates. However, sample-substrate interaction in 2D TMDs is not yet fully understood due to the lack of systematic studies by techniques that are sensitive to 2D TMD-substrate interaction. This work systematically investigates the interaction between tungsten disulfide (WS_(2)) monolayers and substrates by low-frequency Raman spectroscopy, which is very sensitive to WS_(2)-substrate interaction. Strong coupling with substrates is clearly revealed in chemical vapor deposition (CVD)-grown monolayer WS_(2) by its low-wavenumber interface mode. It is demonstrated that the enhanced sample-substrate interaction leads to tensile strain on monolayer WS_(2), which is induced during the cooling process of CVD growth and could be released for monolayer WS_(2) sample after transfer or fabricated by an annealing-free method such as mechanical exfoliation. These results not only suggest the effectiveness of low-frequency Raman spectroscopy for probing sample-substrate interactions in 2D TMDs, but also provide guidance for the design of high-performance devices with the desired sample-substrate coupling strength based on 2D TMDs.Qian Xiang Xiaofei Yue Yanlong Wang Bin Du Jiajun Chen Shaoqian Zhang Gang Li Chunxiao Cong Ting Yu Qingwei Li Yuqi Jin 2021Nano Research2021,14,11:1
16Linear polyketides produced by co-culture of Penicillium crustosum and Penicillium fellutanum显示文摘Two new polyketides, penifellutins A (1) and B (2), possessing a 22 carbon linear skeleton, were isolated from a co-culture of the deep-sea-derived fungi Penicillium crustosum PRB-2 and Penicillium fellutanum HDN14-323. Meanwhile, two esterification products of 1, penifellutins C (3) and D (4), were obtained because compound 1 could be esterified spontaneously when stored in methanol. Their configurations were difficult to determine because of chiral central crowdedness, structural flexibility and instability. As such, we solved this issue by comprehensively using Mo2(OAc)4-based CD experiments, density functional theory calculation of 13C NMR, DP4 + probability analysis and many chemical reactions, including making acetonide derivative, Mosher’s method, PGME method, etc. Compounds 1 and 2 show obvious inhibitory activity on the liver hyperplasia of zebrafish larvae at a concentration of 10 μmol/L, while 3 and 4 show no activity, indicating that two carboxyls in the structure are important active sites.Guihong Yu Peng Sun Reyilamu Aierken Chunxiao Sun Zhenzhen Zhang Qian Che Guojian Zhang Tianjiao Zhu Qianqun Gu Mingyu Li Dehai Li 2022Marine Life Science & Technology2022,4,2:1
17Catalytic mechanism of manganese ions and visible light on chalcopyrite bioleaching in the presence of Acidithiobacillus ferrooxidans显示文摘The bioleaching of chalcopyrite is low cost and environmentally friendly,but the leaching rate is low.To explore the mechanism of chalcopyrite bioleaching and improve its leaching rate,the effect and mechanism of manganese ions(Mn^(2+))and visible light on chalcopyrite mediated by Acidithiobacillus ferrooxidans(A.ferrooxidans)were discussed.Bioleaching experiments showed that when both Mn^(2+)and visible light were present,the copper extraction was 14.38%higher than that of the control system(without Mn^(2+)and visible light).Moreover,visible light and Mn^(2+)promoted the growth of A.ferrooxidans.Scanning electron microscopy(SEM)and energy dispersive spectrometer(EDS)analysis revealed that Mn^(2+)promoted the formation of extracellular polymeric substance(EPS)on the surface of chalcopyrite,changed the morphology of A.ferrooxidans,enhanced the adsorption of bacteria on chalcopyrite surface with light illumination,and thus promoted the bioleaching of chalcopyrite.UV–vis absorbance spectra indicated that Mn^(2+)promoted the response of chalcopyrite to visible light and enhanced the catalytic effect of visible light on chalcopyrite bioleaching.Based on X-ray photoelectron spectroscopy(XPS),the relevant sulfur speciation of chalcopyrite before and after bioleaching were analyzed and the results revealed that visible light and Mn^(2+)promoted chalcopyrite bioleaching by reducing the formation of passivation layer(S_(n)^(2-)/S0).Investigation into electrochemical results further indicated that Mn^(2+)and visible light improved the electrochemical activity of chalcopyrite,thus increasing the bioleaching rate.Chunxiao Zhao Baojun Yang Rui Liao Maoxin Hong Shichao Yu Jun Wang Guanzhou Qiu 2022Chinese Journal of Chemical Engineering2022,35,1:1

20The parameters in the band-anticrossing model for In_xGa_(1-x)N_yP_(1-y) before and after annealing显示文摘We investigate the parameters in the band-anticrossing (BAC) model for GaNP and InGaPN in this work. The parameters in the BAC model for GaNP and InGaNP are obtained by fitting experimental data. It is found that the band gap bowing of InGaNP is stronger than that of InGaNAs. The effects of annealing on the parameters in the BAC model for InGaNP are also discussed in this work. In addition, the origins for improving luminescence efficiency by annealing are explained. It is relative to the forming of more In-N clusters.ZHAO ChuanZhen ZHANG Rong LIU Bin YU LiYuan TANG ChunXiao XIE ZiLi XIU XiangQian ZHENG YouDou 2011Science China(Physics,Mechanics & Astronomy)2011,54,12:1
