| 1 | Microfossils and molecular records in oil shales of the Songliao Basin and implications for paleo-depositional environment显示文摘Several oil shale beds, over 10 m thick, occur at the base of the first member of the Upper Cretaceous Qingshankou Formation (K2qn1) in the Songliao Basin. They act both as excellent source rocks for conventional oil and as potential oil deposit for shale oil production. Here we combine micropaleon-tology with organic geochemistry to investigate the paleo-depositional environment and organic source characteristics of the oil shales and black shales. Our results indicate that algal remains are dominant microfossils in K2qn1 oil shales, and their relatively high abundance suggests a major algal thriving event during the oil shale deposition. The presence of fresh water and brackish water species, Sentusidinium, Vesperopsis and Nyktericysta, and marine or brackish water deltaic and lagoonal species such as Kiokansium and Dinogymniopsis demonstrate that this paleo-continental lake was influenced by marine transgressions at the time of K2qn1 oil shale formation. The extremely low pristine/phytane ratios, relatively high abundance of gammacerane and 4-methyl steranes, and low δ 13C values of C14-C37 n-alkanes in the oil shale organic extracts indicate the deposition of oil shales in anoxic and highly stratified water columns and the significant contribution of lacustrine algae to sedimentary organic matter. High molecular-weight paraffinic hydrocarbons with unusually high abundance of nC43, nC45, and nC47 may be related to special algal species associated with marine transgression events. The giant water body of Songliao paleo-lake and the change in the organic and chemical environment (such as nutrition source and water column salinity) associated with seawater transgression into the lake are among the most important reasons for oil shales in the Songliao Basin being different from mudstone and oil shale in other rifted basins. | FENG ZiHui FANG Wei WANG Xue HUANG ChunYan HUO QiuLi ZHANG JuHe HUANG QingHua ZHANG Lei | 2009 | Science China Earth Sciences2009，52，10： | 12 |
| 2 | Distribution and significance of C~_(40) alkanes in the extracts of Cretaceous source rocks from the Songliao Basin显示文摘Source rock extracts and crude oils from the Songliao Basin were analyzed by high-temperature gas chromatography (HTGC), gas chromatography-mass spectrometry (HTGC-MS) and gas chromatography-isotope ratio-mass spectrometry (GC-IRMS), for high molecular-weight alkanes. The distributions of n-alkanes in the Nenjiang Formation extracts are in the C14―C63 range; a bimodal distribution occurs in the C-21 and C21―40 regions. The C30―C37 n-alkanes are accompanied by C29―C35 hopanes, whereas the high molecular-weight C45―C47 n-alkanes co-occur with abundant isoalkanes, alkylcyclohexanes and alkylcyclopentanes. The high δ 13C values of the n-alkanes and the microscopic maceral compositions indicate a highly diversified organic source input for the Nenjiang Formation source rocks, ranging from aquatic plants, blue alge-bacteria, to land plant material. In contrast, n-alkanes in the rock extracts of the Qingshankou Formation are characterized by a single modal distribution, with relatively low abundances of C29―C35 hopanes, but high molecular-weight isoalkanes, alkylcyclohexanes and alkylcyclopentanes. The relatively low δ 13C values of C22―C44 n-alkanes and organic material compositions indicate that the source rocks in the Qingshankou Formation contain dominantly type I algal organic matter. The relative abundance of C+40 compounds in source rocks changes little at low maturity stage, but decreases drastically at higher maturity levels, with a concurrent reduction in the odd/even carbon predominance. In crude oils, in contrast, the relative abundance of C+40 compounds appears to relate closely with the oil source and oil viscosity. | FENG ZiHui FANG Wei ZHANG JuHe LI ZhenGuang HUANG ChunYan WANG Xue ZHAO QinLing HUO QiuLi | 2007 | Science China Earth Sciences2007，50，10： | 10 |
| 3 | The chromosome-level Hemerocallis citrina Borani genome provides new insights into the rutin biosynthesis and the lack of colchicine显示文摘Hemerocallis citrina Borani(huang hua cai in Chinese)is an important horticultural crop whose flower buds are widely consumed as a delicious vegetable in Asia.Here we assembled a high-quality reference genome of H.citrina using single-molecule sequencing and Hi-C technologies.The genome assembly was 3.77 Gb and consisted of 3183 contigs with a contig N50 of 2.09 Mb,which were further clustered into 11 pseudochromosomes.A larger portion(3.25 Gb or 86.20%)was annotated as a repetitive content and 54,295 protein-coding genes were annotated in the genome.Genome evolution analysis showed that H.citrina experienced a recent whole-genome duplication(WGD)event at~15.73 million years ago(Mya),which was the main factor leading to many multiple copies of orthologous genes.We used this reference genome to predict 20 genes involved in the rutin biosynthesis pathway.Moreover,our metabolomics data revealed neither colchicine nor its precursors in H.citrina,challenging the long-standing belief that this alkaloid causes poisoning by the plant.The results of our disruptive research are further substantiated by our genomic finding that H.citrina does not contain any genes involved in colchicine biosynthesis.The high-quality genome lays a solid foundation for genetic research and molecular breeding of H.citrina. | Zhixing Qing Jinghong Liu Xinxin Yi Xiubin Liu Guoan Hu Jia Lao Wei He Zihui Yang Xiaoyan Zou Mengshan Sun Peng Huang Jianguo Zeng | 2021 | Horticulture Research2021，8，1： | 6 |
| 4 | Depositional environment of terrestrial petroleum source rocks and geochemical indicators in the Songliao Basin显示文摘To determine geochemical indicators for depositional environment favored by terrestrial petroleum source rocks, we selected 40 source rock samples from the Late Cretaceous Qingshankou Formation (K2qn) and the first member of Nenjiang Formation (K2n1) in the Songliao Basin to qualify saturate fraction and aromatic fraction using GC-HRT (gas chromatography high reso lution time-of-flight mass spectrometry) and quantify important biomarkers using GC-MS. The results reveal that source rocks from the 1st member of Qingshankou Formation (K2qn1) are characterized by not only high contents of terpanes, regular ster anes and 4-methylsteranes but also high contents of dinosteranes, C31 steranes and aryl isoprenoids. Presence of specific bi omarkers like elementary sulfur and lanostanes indicates a depositional environment of lagoon characterized by water stratifi cation and high salinity. In the 2nd-3rd members of Qingshankou Formation (K2qn2+3), source rocks contain lower contents of biomarkers, indicating a depositional environment of shallow fresh-water lake delta. Source rocks in the K2n1 contain high contents of terpanes, regular steranes and 4-methylsteranes but lower contents of dinosteranes, C31 steranes and aryl isopre noids, indicating a depositional environment of fresh-brackish open lake characterized by low salinity and poor water stratifi cation, where organic matter is seriously altered by bacteria. Overall analysis shows that primary geochemical indicators for terrestrial petroleum source rocks are as follows: 1) C30 hopanes > 1500 ppm; 2) gammacerane >190 ppm; 3) C27 steranes >200 ppm; 4) 4-methylsteranes >100 ppm; 5) aryl isoprenoids > 3 ppm; 6) dehydroxyl-vitamin E >10 ppm. | FENG ZiHui FANG Wei LI ZhenGuang WANG Xue HUO QiuLi HUANG ChunYan ZHANG JuHe ZENG HuaSen | 2011 | Science China Earth Sciences2011，54，9： | 6 |
| 5 | A Single-cell Transcriptome Atlas of Cashmere Goat Hair Follicle Morphogenesis显示文摘Cashmere,also known as soft gold,is produced from the secondary hair follicles(SHFs)of cashmere goats.The number of SHFs determines the yield and quality of cashmere;therefore,it is of interest to investigate the transcriptional profiles present during cashmere goat hair follicle development.However,mechanisms underlying this development process remain largely unexplored,and studies regarding hair follicle development mostly use a murine research model.In this study,to provide a comprehensive understanding of cellular heterogeneity and cell fate decisions,single-cell RNA sequencing was performed on 19,705 single cells of the dorsal skin from cashmere goat fetuses at induction(embryonic day 60;E60),organogenesis(E90),and cytodifferentiation(E120)stages.For the first time,unsupervised clustering analysis identified 16 cell clusters,and their corresponding cell types were also characterized.Based on lineage inference,a detailed molecular landscape was revealed along the dermal and epidermal cell lineage developmental pathways.Notably,our current data also confirmed the heterogeneity of dermal papillae from different hair follicle types,which was further validated by immunofluorescence analysis.The current study identifies different biomarkers during cashmere goat hair follicle development and has implications for cashmere goat breeding in the future. | Wei Ge Weidong Zhang Yuelang Zhang Yujie Zheng Fang Li Shanhe Wang Jinwang Liu Shaojing Tan Zihui Yan Lu Wang Wei Shen Lei Qu Xin Wang | 2021 | Genomics, Proteomics & Bioinformatics2021，19，3： | 3 |
| 6 | Characteristics of remaining oil viscosity in water-and polymer-flooding reservoirs in Daqing Oilfield显示文摘The experimental analysis of 21 crude oil samples shows a good correlation between high molecular-weight hydrocarbon components (C 40+) and viscosity.Forty-four remaining oil samples extracted from oil sands of oilfield development coring wells were analyzed by high-temperature gas chromatography (HTGC),for the relative abundance of C 21-,C 21-C 40 and C 40+ hydrocarbons.The relationship between viscosity of crude oil and C 40+ (%) hydrocarbons abundance is used to expect the viscosity of remaining oil.The mobility characteristics of remaining oil,the properties of remaining oil,and the next displacement methods in reservoirs either water-flooded or polymer-flooded are studied with rock permeability,oil saturation of coring wells,etc.The experimental results show that the hydrocarbons composition,viscosity,and mobility of remaining oil from both polymer-flooding and water-flooding reservoirs are heterogeneous,especially the former.Relative abundance of C 21- and C 21-C 40 hydrocarbons in polymer-flooding reservoirs is lower than that of water-flooding,but with more abundance of C 40+ hydrocarbons.It is then suggested that polymer flooding must have driven more C 40- hydrocarbons out of reservoir,which resulted in relatively enriched C 40+,more viscous oils,and poorer mobility.Remaining oil in water-flooding reservoirs is dominated by moderate viscosity oil with some low viscosity oil,while polymer-flooding mainly contained moderate viscosity oil with some high viscosity oil.In each oilfield and reservoir,displacement methods of remaining oil,viscosity,and concentration by polymer-solution can be adjusted by current viscosity of remaining oil and mobility ratio in a favorable range.A new basis and methods are suggested for the further development and enhanced oil recovery of remaining oil. | XU ZhengShun,ZHANG JuHe,FENG ZiHui,FANG Wei & WANG FengLan Exploration and Development Research Institute,Daqing Oilfield Company Ltd.,Daqing 163712,China | 2010 | Science China Earth Sciences2010，53，1： | 3 |

| 8 | Effect of end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture in pancreatic surgery显示文摘The aim of this paper is to summarize the methods of pancreaticojejunostomy in the pancreatic operation and to study the safety and feasibility of a new operative method called end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture to prevent fistula of pancreaticojejunostomy.Eight-three patients with pancreaticoduodenectomy in the 3rd Hospital,Jilin University from 2001 January to 2006 April were reviewed.The incidences of pancreatic fistula with different types of pancreaticojejunostomy were compared.The overall incidence rate of pancreatic fistula was 26.5%(22/83).No pancreatic fistula occurred in end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture.The incidence rate of the fistula following end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture was significantly lower than that of traditional end-to-end pancreaticojejunostomy[40%,(10/25),P<0.01]and end-to-side pancreaticojejunostomy[27.3%,(12/44),P<0.05],but no significant difference(P>0.05)between traditional end-to-end pancreaticojejunostomy and end-to-side pancreaticojejunostomy was discovered.End-to-end invagination pancreaticojejunostomy with circle discontinuous U suture has a definite effect on avoiding pancreatic fistula following pancreaticojejunostomy and is worth being recommended.But the cases were limited,so this method would still need to be observed and confirmed further in the future. | ZHANG Xuewen XUAN Wei JIANG Tao JI Degang YANG Yongsheng ZHANG Dan XIE Yingjun MENG Zihui ZHAO Jisheng | 2007 | Frontiers of Medicine2007，1，1： | 1 |
| 9 | Experimental and numerical study of a gas cyclone with a central filter显示文摘This paper studies a novel gas cyclone with a cylindrical fiter face installed in the center from the vortex finder to the bottom hopper.The experimental results show that this composite cyclone has a higher collection fficiency and a lower pressure drop than the original cyclone.The mechanisms for the improvement are analyzed by both physical experiments and numerical simulations.By measuring dust samples collected at different places it is revealed that the center filter can prevent fine particles from entering the inner vortex and escaping,which accounts for the increase of the collection eficiency.In addition,the flow field of the composite cyclone is simulated by computational fluid dynamics and compared with that of the original cyclone.The analysis shows that with the filter layer installed,the swirling flow disappears in the vortex finder,which decreases the kinetic energy dissipation and hence lowers the pressure drop. | Zihui Zhang Sijie Dong Kejun Dong Li'an Hou Wenzheng Wang Yi Wei Bo Wang | 2022 | Particuology2022，20，4： | 1 |
| 10 | Crude-oil hydrocarbon composition characteristics and oil viscosity prediction in the northern Songliao Basin显示文摘Crude oil hydrocarbon composition characteristics and oil viscosity prediction are important bases in petroleum exploration.A total of 54 oil/heavy-oil samples and 17 oil sands were analyzed and quantified using both comprehensive 2D gas chromatography(GC×GC)and comprehensive 2D gas chromatography/time-of-flight mass spectrometry(GC×GC/TOFMS).The results show that crude oil in the West slope is mainly heavy oil and its hydrocarbon composition is characterized overall by paraffins>mono-aromatics>naphthenes>non-hydrocarbons>di-aromatics>tri-aromatics>tetra-aromatics.Aromatics are most abundant and non-hydrocarbons are least abundant,whilst content differences among paraffins,naphthenes,aromatics,and non-hydrocarbons are less than 15%.There are two types of heavy oil,secondary type and mixing type.Biodegradation is the main formation mechanism of heavy oil.Biodegradation levels cover light biodegradation,moderate biodegradation,and severe biodegradation.With increasing biodegradation,paraffin content decreases while contents of aromatics and nonhydrocarbons increase.In contrast,naphthene content increases first and then decreases with increasing biodegradation.In severe biodegradation stage,naphthenes decrease more quickly than aromatics and non-hydrocarbons.This provides a new method for studying oil/heavy-oil biodegradation mechanism and biodegradation resistance of different hydrocarbons at different biodegradation stages.In the Longhupao-Daan terrace and Qijia-Gulong depression,most crude oil is conventional oil.Its composition is dominated by paraffins with the lowest content of aromatics.In some casual oil wells from the Longhupao-Daan terrace,crude oil from Saertu oil reservoirs is moderately biodegraded whereas crude oil from Putaohua oil reservoir is lightly biodegraded.Chemical parameters using saturate hydrocarbons and aromatics are usually not suitable for determining organic type and thermal maturity of biodegraded oil,especially of moderately or severely biodegraded oil,whilst Ts/(Ts+Tm)ratio can be used to determine thermal maturity of both conventional crude oil and heavy oil. | ZHANG JuHe FENG ZiHui FANG Wei HUO QiuLi ZHANG Kun LI JingKun ZENG HuaSen ZHANG BoWei | 2014 | Science China Earth Sciences2014，57，2： | 1 |
| 11 | Femoral mechanical performance of precocial and altricial birds:a simulation study显示文摘Background:As the major load-bearing structures,bones exhibit various properties related to mechanical perfor-mance to adapt to different locomotor intensities.The habits and ontogenetic changes of locomotion in animals can,thus,be explored by assessing skeletal mechanical performance.Methods:In this study,we investigated the growing femoral mechanical performance in an ontogenetic series of Cabot’s Tragopans(Tragopan caboti)and Pigeons(Columba livia domestica).Micro-computed tomography-based finite element analysis was conducted to evaluate the stress,strain,and strain energy density(SED)of femora under axial and radial loading.Results:Femora deflected medio-laterally and dorso-ventrally under axial and radial loading,respectively.Femora deformed and tensed more severely under radial loading than axial loading.In adult individuals,Cabot’s Tragopans had lower strain and SED than pigeons.During ontogeny,the strain and SED of pigeons decreased sharply,while Cabot’s Tragopans showed moderately change.The structural properties of hatchling pigeons are more robust than those of hatchling Cabot’s Tragopans.Conclusions:Limb postures have dominant effect on skeletal deformation.The erect posture is preferred by large mammals and birds to achieve a high safety factor of bones during locomotion.Adult Cabot’s Tragopans have stronger femora than pigeons,reflecting a better bone adaption to the terrestrial locomotion of the studied pheas-ant species.Changes in strain and SED during growth reflect the marked difference in locomotor ability between precocial and altricial hatchlings.The femora of hatchling Cabot’s Tragopans were built with better energy efficiency than deformation resistance,enabling optimized mechanical performance.In contrast,although weak in mechani-cal function at the time of hatching,pigeon femora were suggested to be established with a more mature structural design as a prerequisite for rapid growth.These results will be helpful for studies regarding developmental patterns of fossil avian species. | Xinsen Wei Zihui Zhang | 2021 | Avian Research2021，12，2： | 1 |

| 13 | Crosstalk between PC 12 cells and endothelial cells in an artificial neurovascular niche constructed by a dual-functionalized selfassembling peptide nanofiber hydrogel显示文摘The coordination between neurogenesis and angiogenesis plays an important role in nerve tissue development and regeneration.Recently,using bioactive materials to drive neurogenic and angiogenic responses has gained increasing attention.Understanding the neurovascular link between regulatory cues offers valuable insight into the mechanisms underlying nerve regeneration and the design of new bioactive materials.In this study,we utilized a dual-functionalized peptide nanofiber hydrogel presenting the brain-derived neurotrophic factor and vascular endothelial growth factor mimetic peptides RGIDKRHWNSQ(RGI)and KLTWQELYQLKYKGI(KLT)to construct an artificial neurovascular microenvironment.The dual-functionalized peptide nanofiber hydrogel enhanced the neurite outgrowth of pheochromocytoma(PC12)cells and tube-like structures formation of human umbilical vein endothelial cells(HUVECs)in vitro,and promoted rapid lesion infiltration of neural and vascular cells in a rat brain injury model.Using indirect co-culture models,we found that the dual-functionalized peptide hydrogel effectively mediated neurovascular crosstalk by regulating secretion of paracrine factors from PC12 cells and HUVECs.When the two cells types were directly co-cultured on the dua卜functionalized peptide hydrogel,the efficiency of cell-cell communication was enhanced,which further accelerated the differentiation and maturation of PC12 cells with an increased number of pseudopodia and spread morphology,and HUVECs tube-like structure formation.In summary,the dual-functionalized peptide nanofiber hydrogel successfully formed an artificial neurovascular niche to directly regulate the behaviors of neural and vascular cells and promote their neurovascular crosstalk through paracrine signaling and direct cell-cell contact. | Zhe Zhang Yi Chai He Zhao Shuhui Yang Wei Liu Zihui Yang Weilong Ye Chenlong Wang Xiaohan Gao Xiangdong Kong Xiaodan Sun Lingyun Zhao Tuoyu Chen Yuqi Zhang Jiaju Lu Xiumei Wang | 2022 | Nano Research2022，15，2： | 0 |
| 14 | Types of the Cambrian platform margin mound-shoal complexes and their relationship with paleogeomorphology in Gucheng area,Tarim Basin,NW China显示文摘Based on the observation of outcrops and cores,thin section identification,restoration of paleogeomorphology by residual thickness method,fine description of seismic facies,etc.,the coupling relationships between the development patterns of various types of Cambrian platform margin mound-shoal complexes and paleogeomorphology in the Gucheng area of Tarim Basin have been examined.The Cambrian platform margin mound-shoal complex is divided into mound base,mound core,mound front,mound back and mound flat microfacies,which are composed of dolomites of seven textures with facies indication.The different paleogeomorphology before the deposition of mound-shoal complex in each period was reconstructed,and three types of mound-shoal complex sedimentary models corresponding to the paleogeomorphologies of four stages were established:namely,the first stage of gentle slope symmetric accretion type,the second stage of steep slope asymmetric accretion type and the third and fourth stages of steep slope asymmetric progradation type.Their microfacies are respectively characterized by-mound base-mound back+(small)mound core+mound front-mound flat'symmetric vertical accretion structure,'mound base-(large)mound core+mound front-mound flat'asymmetric vertical accretion structure,'mound base-(small)mound core+mound front-mound flat'asymmetric lateral progradation structure.With most developed favorable reservoir facies belt,the steep slope asymmetric accretion type mound-shoal complex with the characteristics of'large mound and large shoal'is the exploration target for oil and gas reservoir. | ZHANG Junlong HU Mingyi FENG Zihui LI Qiang HE Xiangxiang ZHANG Bin YAN Bo WEI Guoqi ZHU Guangyou ZHANG You | 2021 | Petroleum Exploration and Development2021，48，1： | 0 |
| 15 | Model-based assessment of muscle forces and strain distribution in the femur of Cabot’s Tragopans(Tragopan caboti)显示文摘The hindlimbs play a crucial role in bird locomotion,making the biomechanical properties of the musculoskeletal system in these limbs a focal point for researchers studying avian behaviour.However,a comprehensive analysis of the mechanical performance within the long bones of hindlimbs during locomotion remains lacking.In the present study,the strain and deformation of the femur of Cabot’s Tragopans(Tragopan caboti)were estimated.We employed inverse simulation to calculate the force and moment of femoral muscles during mid-stance terrestrial locomotion and conducted finite element analysis to calculate femoral strain.Results showed that during mid-stance,the femur experiences combined deformation primarily characterized by torsion,bending,and compression.It emphasises the importance of considering the influence of varying loads on bone adaptation when investigating bone form-function relationships.Muscles were found to play a significant role in offsetting joint loads on the femur,subsequently reducing the deformation and overall strain on the bone.This reduction enhances femoral safety during locomotion,allowing birds to meet mechanical demands while maintaining a lightweight bone structure.Notably,the M.iliotrochantericus caudalis significantly reduces torsional deformation of the proximal femur,protecting the vulnerable femoral neck from high fracture risk induced by rotation load.Given that the femur torsion during terrestrial locomotion in birds is associated with changes in hindlimb posture due to their adaptation to flight,the characteristics of M.iliotrochantericus caudalis may provide insight into the locomotor evolution of theropods and the origin of avian flight. | Xinsen Wei Zihui Zhang | 2023 | Avian Research2023，14，4： | 0 |
| 16 | S-nitrosylation of EMMPRIN influences the migration of HSCs and MMP activity in liver fibrosis显示文摘The mechanism of extracellular matrix metalloproteinase inducer(EMMPRIN)in the regulation of liver fibrosis has not been clarified.This study aims to investigate the role of EMMPRIN S-nitrosylation(SNO)in the regulation of hepatic stellate cell(HSC)migration and matrix metalloproteinase(MMP)activities in liver fibrosis.The results from the tissue microarrays and rat/mouse liver tissues suggest that EMMPRIN mRNA and protein levels in the fibrotic livers are lower than those in the corresponding normal control livers,but higher SNO level of EMMPRIN in fibrotic liver area was shown by immunohistochemistry,immunofluorescence staining,and biotin-switch assay conversely in vivo.Primary EMMPRIN comes from hepatocytes and liver sinus epithelial cells(LSECs)rather than quiescent HSCs.To mimic the uptake of extrinsic EMMPRIN,supernatants from mouse primary hepatocytes/293 cells transfected with EMMPRIN wild-type plasmids(WT)and EMMPRIN SNO site(cysteine 87)mutation plasmids(MUT)were collected and added to JS-1/LX2 cell medium.The MUT EMMPRIN diminishes SNO successfully,enhances the activities of MMP2 and MMP9,and subsequently increases HSC migration.In conclusion,SNO of EMMPRIN influences HSC migration and MMP activities in liver fibrosis.This finding may shed light on the possible regulatory mechanism of MMPs in ECM accumulation in liver fibrosis. | Xinyan Zhu Zihui Tang Wei Li Xiaojuan Li Yasuko Iwakiri Fei Liu | 2023 | Acta Biochimica et Biophysica Sinica2023，55，10： | 0 |
| 17 | Quantitative characterization of filamentous fungal promoters on a single-cell resolution to discover cryptic natural products显示文摘Characterization of filamentous fungal regulatory elements remains challenging because of time-consuming transformation technologies and limited quantitative methods.Here we established a method for quantitative assessment of filamentous fungal promoters based on flow cytometry detection of the superfolder green fluorescent protein at single-cell resolution.Using this quantitative method,we acquired a library of 93 native promoter elements from Aspergillus nidulans in a high-throughput format.The strengths of identified promoters covered a 37-fold range by flow cytometry.P_(zipA) and P_(sltA)were identified as the strongest promoters,which were 2.9-and 1.5-fold higher than that of the commonly used constitutive promoter P_(gpdA).Thus,we applied P_(zipA)and P_(sltA)to activate the silent nonribosomal peptide synthetase gene Afpes1 from Aspergillus fumigatus in its native host and the heterologous host A.nidulans.The metabolic products of Afpes1 were identified as new cyclic tetrapeptide derivatives,namely,fumiganins A and B.Our method provides an innovative strategy for natural product discovery in fungi. | Peng-Lin Wei Jie Fan Jingwen Yu Zihui Ma Xian Guo Nancy PKeller Erwei Li Chunbo Lou Wen-Bing Yin | 2023 | Science China(Life Sciences)2023，66，4： | 0 |
| 18 | Kidney-Qi deficiency diagnosed by Deng's diagnosis standard was not correlated with aging based on clinical observation of 90 participants显示文摘OBJECTIVE: To verify the Traditional Chinese Medicine(TCM) theory that kidney-Qi deficiency(KQD)is considered to be the main cause of aging using cross-sectional study.METHODS: Demographic and lifestyle characteristics of 90 healthy participants were collected with a self-administered questionnaire. KQD syndrome was diagnosed according to Deng's diagnosis standard. Creatinine-adjusted urinary 8-hydroxy-2'-deoxyguanosine(8-OH-dG) and 8-isomeric-prostaglandin2α(8-iso-PGF2α), salivary advanced oxidation protein products(AOPPs), malondialdehyde(MDA) and dehydroepiandrosterone-sulfate(DHEA-S) were selected as aging markers and measured using enzyme-linked immunosorbent assay.RESULTS: No significant differences were observed in participant characteristics between the KQD group and non-KQD(NKQD) group(P > 0.05). Levels of 8-OH-dG, 8-iso-PGF2α, AOPPs, and MDA increased with age, except for a slight decrease in8-OH-dG in the older group. The increase in8-iso-PGF2α was significant(P < 0.05). DHEA-S significantly decreased with increasing age(P < 0.01).8-OH-dG levels were higher in the KQD group compared with the NKQD group. Levels of urinary8-iso-PGF2α, salivary AOPPs, and MDA in the KQD group were lower than in the NKQD group. Salivary DHEA-S was higher in the KQD group compared with the NKQD group. However, differences between KQD group and NKQD group were not significant.CONCLUSION: The current results suggested that KQD syndrome, as diagnosed by Deng's standard,does not underlie the aging phenotype. | Zhao Zhengxiao Liu Lumei Tang Zihui Mohammadtursun Nabijan Lu Linwei Li Mihui Lü Yibao Mo Shuming Ma Wenjuan Wang Meng Wei Ying Gong Weiyi Dong Jingcheng | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 0 |
