| 1 | Characterization of drug responses of mini patient-derived xenografts in mice for predicting cancer patient clinical therapeutic response显示文摘Background:Patient-derived organoids and xenografts(PDXs)have emerged as powerful models in functional diag-nostics with high predictive power for anticancer drug response.However,limitations such as engraftment failure and time-consuming for establishing and expanding PDX models followed by testing drug efficacy,and inability to subject to systemic drug administration for ex vivo organoid culture hinder realistic and fast decision-making in selecting the right therapeutics in the clinic.The present study aimed to develop an advanced PDX model,namely MiniPDX,for rapidly testing drug efficacy to strengthen its value in personalized cancer treatment.Methods:We developed a rapid in vivo drug sensitivity assay,OncoVee®MiniPDX,for screening clinically relevant regimens for cancer.In this model,patient-derived tumor cells were arrayed within hollow fiber capsules,implanted subcutaneously into mice and cultured for 7 days.The cellular activity morphology and pharmacokinetics were systematically evaluated.MiniPDX performance(sensitivity,specificity,positive and negative predictive values)was examined using PDX as the reference.Drug responses were examined by tumor cell growth inhibition rate and tumor growth inhibition rate in PDX models and MiniPDX assays respectively.The results from MiniPDX were also used to evaluate its predictive power for clinical outcomes.Results:Morphological and histopathological features of tumor cells within the MiniPDX capsules matched those both in PDX models and in original tumors.Drug responses in the PDX tumor graft assays correlated well with those in the corresponding MiniPDX assays using 26 PDX models generated from patients,including 14 gastric cancer,10 lung cancer and 2 pancreatic cancer.The positive predictive value of MiniPDX was 92%,and the negative predictive value was 81%with a sensitivity of 80%and a specificity of 93%.Through expanding to clinical tumor samples,Min-iPDX assay showed potential of wide clinical application.Conclusions:Fast in vivo MiniPDX assay based on capsule implantation was developed-to assess drug responses of both PDX tumor grafts and clinical cancer specimens.The high correlation between drug responses of paired MiniPDX and PDX tumor graft assay,as well as translational data suggest that MiniPDX assay is an advanced tool for personalized cancer treatment. | Feifei Zhang Wenjie Wang Yuan Long Hui Liu Jijun Cheng Lin Guo Rongyu Li Chao Meng Shan Yu Qingchuan Zhao Shun Lu Lili Wang Haitao Wang Danyi Wen | 2018 | Cancer Communications2018,38,1: | 20 |

| 6 | Quantitative trait locus mapping of yield and plant height in autotetraploid alfalfa(Medicago sativa L.)显示文摘Alfalfa(Medicago sativa L.)is the most widely grown forage legume crop worldwide.Yield and plant height are important agronomic traits influenced by genetic and environmental factors.The objective of this study was to identify quantitative trait loci(QTL)and molecular markers associated with alfalfa yield and plant height.To understand the genetic basis of these traits,a full-sib F1 population composed of 392 individuals was developed by crossing a low-yielding precocious alfalfa genotype(male parent)with a high-yielding latematuring alfalfa cultivar(female parent).The linkage maps were constructed with 3818 single-nucleotide polymorphism(SNP)markers on 64 linkage groups.QTL for yield and plant height were mapped using phenotypic data for three years.Sixteen QTL associated with yield and plant height were identified on chromosomes 1 to 8.Six QTL explained more than 10%of phenotypic variation,representing major loci controlling yield and plant height.One locus on chromosome 1 controlling yield traits had not been identified in previous studies.Three QTL co-located with other QTL(qyield-1 and qheight-7,qheight-5 and qyield-4,qheight-6,and qyield-6).With further validation,the markers closely linked with these QTL may be used for marker-assisted selection in breeding new alfalfa varieties with high yield. | Fei He Ruicai Long Tiejun Zhang Fan Zhang Zhen Wang Xijiang Yang Xueqian Jiang Changfu Yang Xuxin Zhi Mingna Li Longxi Yu Junmei Kang Qingchuan Yang | 2020 | The Crop Journal2020,8,5: | 1 |

| 9 | Genome Assembly of Alfalfa Cultivar Zhongmu-4 and Identification of SNPs Associated with Agronomic Traits显示文摘Alfalfa(Medicago sativa L.)is the most important legume forage crop worldwide with high nutritional value and yield.For a long time,the breeding of alfalfa was hampered by lacking reliable information on the autotetraploid genome and molecular markers linked to important agronomic traits.We herein reported the de novo assembly of the allele-aware chromosome-level genome of Zhongmu-4,a cultivar widely cultivated in China,and a comprehensive database of genomic variations based on resequencing of 220 germplasms.Approximate 2.74 Gb contigs(N50 of 2.06 Mb),accounting for 88.39%of the estimated genome,were assembled,and 2.56 Gb contigs were anchored to 32 pseudo-chromosomes.A total of 34,922 allelic genes were identified from the allele-aware genome.We observed the expansion of gene families,especially those related to the nitrogen metabolism,and the increase of repetitive elements including transposable elements,which probably resulted in the increase of Zhongmu-4 genome compared with Medicago truncatula.Population structure analysis revealed that the accessions from Asia and South America had relatively lower genetic diversity than those from Europe,suggesting that geography may influence alfalfa genetic divergence during local adaption.Genome-wide association studies identified 101 single nucleotide polymorphisms(SNPs)associated with 27 agronomic traits.Two candidate genes were predicted to be correlated with fall dormancy and salt response.We believe that the alleleaware chromosome-level genome sequence of Zhongmu-4 combined with the resequencing data of the diverse alfalfa germplasms will facilitate genetic research and genomics-assisted breeding in variety improvement of alfalfa. | Ruicai Long Fan Zhang Zhiwu Zhang Mingna Li Lin Chen Xue Wang Wenwen Liu Tiejun Zhang Long-Xi Yu Fei He Xueqian Jiang Xijiang Yang Changfu Yang Zhen Wang Junmei Kang Qingchuan Yang | 2022 | Genomics, Proteomics & Bioinformatics2022,20,1: | 1 |

| 12 | Transverse vibration of pre-tensioned nonlocal nanobeams with precise internal axial loads显示文摘This paper investigates the transverse vibration of a simply supported nanobeam with an initial axial tension based on the nonlocal stress field theory with a nonlocal size parameter. Considering an axial elongation due to transverse vibration, the internal axial tension is not precisely equal to the external initial tension. A sixth-order nonlinear partial differential equation that governs the transverse vibration for such nonlocal nanobeam is derived. Using a perturbation method, the relation between natural frequency and nonlocal nanoscale parameter is derived and the transverse vibration mode is solved. The external axial tension and nonlocal nanoscale parameter are proven to play significant roles in the nonlinear vibration behavior of nonlocal nanobeams. Such effects enhance the natural frequency and stiffness as compared to the predictions of the classical continuum mechanics models. Additionally, the frequency is higher if the precise internal axial load is considered with respect to that when only the approximate internal axial tension is assumed. | LI Cheng LIM C. W.

| 14 | A molecular dynamics and computational study of human KAT3 involved in KYN pathway显示文摘Kynurenine aminotransferases (KATs) catalyze the transamination of kynurenine (KYN) pathway and endogenous KYNs have been suggested to highly correlate to abnormal brain diseases. HKAT3 is a key member of KAT family, while the binding mechanism of KYN and cofactor with HKAT3 has not been determined yet. In this study, we focus on the structure-function relationship among KYN, cofactor and HKAT3. The binding models of KYN complex and KYN&cofactor complex were obtained and were studied by molecular dynamics (MD) simulations. We identified several critical residues and influence of conformational changes in human kynurenine aminotransferase 3 (HKAT3) complexes. The cofactor may contribute largely not only to the catalysis, but also to the binding. In addition, a hypothesis is proposed that a strong hydrophobic interaction between Tyr159 and Lys280 may influence the binding mode and the binding region of the substrate and the cofactor. Our results will be a good starting point for further determination of the biological role. | XU Yu ZHENG QingChuan YU LiYing ZHANG HongXing SUN ChiaChung | 2013 | Science China Chemistry2013,56,4: | 0 |
| 15 | Genotype analysis of rotaviruses isolated from children during a phase III clinical trial with the hexavalent rotavirus vaccine in China显示文摘The oral hexavalent live human-bovine reassortant rotavirus vaccine(RV6)developed by Wuhan Institute of Biological Products Co.,Ltd(WIBP)has finished a randomized,placebo-controlled phase III clinical trial in four provinces of China in 2021.The trail demonstrated that RV6 has a high vaccine efficacy against the prevalent strains and is safe for use in infants.During the phase III clinical trial(2019–2021),200 rotavirus-positive fecal samples from children with RV gastroenteritis(RVGE)were further studied.Using reverse transcription-polymerase chain reaction and high-throughput sequencing,VP7 and VP4 sequences were obtained and their genetic characteristics,as well as the differences in antigenic epitopes of VP7,were analyzed in detail.Seven rotavirus genotypes were identified.The predominant rotavirus genotype was G9P[8](77.0%),followed by prevalent strains G8P[8](8.0%),G3P[8](3.5%),G3P[9](1.5%),G1P[8](1.0%),G2P[4](1.0%),and G4P[6](1.0%).The amino acid sequence identities of G1,G2,G3,G4,G8,and G9 genotypes of isolates compared to the vaccine strains were 98.8%,98.2%–99.7%,88.4%–99.4%,98.2%,94.2%–100%,and 93.9%–100%,respectively.Notably,the vaccine strains exhibited high similarity in amino acid sequence,with only minor differences in antigenic epitopes compared to the Chinese endemic strains.This supports the potential application of the vaccine in preventing diseases caused by rotaviruses. | Wenqi Zou Qingchuan Yu Yan Liu Qingliang Li Hong Chen Jiamei Gao Chen Shi Ying Wang Wei Chen Xuan Bai Biao Yang Jiuwei Zhang Ben Dong Bo Ruan Liuyifan Zhou Gelin Xu Zhongyu Hu Xiaoming Yang | 2023 | Virologica Sinica2023,38,6: | 0 |
| 16 | Nanomechanical assay for ultrasensitive and rapid detection of SARS-CoV-2 based on peptide nucleic acid显示文摘The massive global spread of the COVID-19 pandemic makes the development of more effective and easily popularized assays critical.Here,we developed an ultrasensitive nanomechanical method based on microcantilever array and peptide nucleic acid(PNA)for the detection of severe acute respiratory syndrome-coronavirus-2(SARS-CoV-2)RNA.The method has an extremely low detection limit of 0.1 fM(105 copies/mL)for N-gene specific sequence(20 bp).Interestingly,it was further found that the detection limit of N gene(pharyngeal swab sample)was even lower,reaching 50 copies/mL.The large size of the N gene dramatically enhances the sensitivity of the nanomechanical sensor by up to three orders of magnitude.The detection limit of this amplification-free assay method is an order of magnitude lower than RT-PCR(500 copies/mL)that requires amplification.The non-specific signal in the assay is eliminated by the in-situ comparison of the array,reducing the false-positive misdiagnosis rate.The method is amplification-free and label-free,allowing for accurate diagnosis within 1 h.The strong specificity and ultrasensitivity allow single base mutations in viruses to be distinguished even at very low concentrations.Also,the method remains sensitive to fM magnitude lung cancer marker(miRNA-155).Therefore,this ultrasensitive,amplification-free and inexpensive assay is expected to be used for the early diagnosis of COVID-19 patients and to be extended as a broad detection tool. | Yu Wang Tianhao Yan Kainan Mei Depeng Rao Wenjie Wu Ye Chen Yongpei Peng Jianye Wang Shangquan Wu Qingchuan Zhang | 2023 | Nano Research2023,16,1: | 0 |
| 17 | 用于预测癌症患者临床治疗方案的小鼠mini人源肿瘤异种移植模型的建立显示文摘背景与目的患者来源的类器官(patient-derived organoids,PDOs)和异种移植物(patientderivedxenografts,PDXs)具有较强的预测抗癌药物药效的能力,是功能检测的重要模型。然而,移植失败、构建PDX模型和随后检测药效的耗时过长、体外器官培养无法进行系统性给药等限制因素严重阻碍了其在临床上的应用,无法快速地筛选正确、可行的治疗方案。本研究旨在开发一种名为'miniPDX'的改良的PDX模型,用于快速检测药效,提高其在个体化癌症治疗中的应用价值。方法我们开发了一种快速检测体内药物敏感性的方法——OncoVee?MiniPDX,用于筛选癌症临床治疗方案。本模型将患者来源的肿瘤细胞注入中空纤维胶囊内,皮下植入小鼠体内培养7 d。系统评价了细胞的活性形态和药代动力学。以PDX为对照评估miniPDX的性能(敏感性、特异性、阳性和阴性预测值)。分别采用PDX和miniPDX模型以肿瘤生长抑制率和肿瘤细胞生长抑制率为指标检测药物反应。评价miniPDX模型对临床疗效的预测能力。结果MiniPDX胶囊内肿瘤细胞的形态学和组织病理学特征与PDX模型和原发肿瘤细胞的形态学和组织病理学特征均保持一致。26例(包括14例胃癌、10例肺癌和2例胰腺癌)来自患者的PDX肿瘤移植试验的药物反应与相应的miniPDX试验的药物反应结果具有良好的相关性。MiniPDX阳性预测值为92%,阴性预测值为81%,敏感性为80%,特异性为93%。通过扩大临床肿瘤样本,miniPDX检测显示出广泛的临床应用潜力。结论我们建立了基于胶囊植入技术的miniPDX快速体内检测方法,用于评估PDX肿瘤移植物和临床肿瘤标本的药物反应。PDX模型和其对应的miniPDX药效结果具有良好的相关性,结合转化研究数据最终表明miniPDX模型是一种先进的个体化癌症治疗工具。 | Feifei Zhang Wenjie Wang Yuan Long Hui Liu Jijun Cheng Lin Guo Rongyu Li Chao Meng Shan Yu Qingchuan Zhao Shun Lu Lili Wang Haitao Wang Danyi Wen | 2019 | 癌症2019,38,4: | 0 |
| 18 | Combining methylated SEPTIN9 and RNF180 plasma markers for diagnosis and early detection of gastric cancer显示文摘Dear Editor,Early diagnosis is critical for successful treatment of gastric adenocarcinoma(GA).However,the sensitivities of tumor markers carcinoembryonic antigen(CEA),cancer antigen 19-9(CA19-9)and CA72-4 for GA detection are approximately 20%[1],and the sensitivities of all markers combined for early gastric cancer detection is still very low[2].DNA methylation plays a major role in tumorigenesis and therefore has obvious potential as a non-invasive biomarker for cancer detection[3].Through genome-wide methylation analysis and histological verification,we previously identified ring finger protein 180(RNF180)as a novel preferentially methylated gene in GA[4,5]. | Yongzhan Nie Xianchun Gao Xiqiang Cai Zhen Wu Qiaoyi Liang Guobing Xu Na Liu Peng Gao Jingyu Deng Hongzhi Xu Zhanlong Shen Changqi Cao Fenrong Chen Nannan Zhang Yongxi Song Mingjun Sun Chengyin Liu Guangpeng Zhou Weili Han Jianhua Dou Huahong Xie Liping Yao Zhiguo Liu Gang Ji Xin Wang Qingchuan Zhao Lei Shang Daiming Fan Xiaoliang Han Jianlin Ren Han Liang Zhenning Wang Jinhai Wang Qi Wu Jun Yu Kaichun Wu the MAGIS Study Group | 2023 | Cancer Communications2023,43,11: | 0 |
| 19 | Nanomechanical vibration profiling of oocytes显示文摘The beginning of a mammalian life commences with a fertilized oocyte.The study of oocytes is certainly one of the most intriguing scientific questions of our time.Herein,we studied oocytes from a mechanical perspective and characterized the typical life activities of oocytes by nanomechanical vibrations.During the development of oocytes from the germinal vesicle(GV)stage to the zygotes,the GV stage oocytes induced a significant nanomechanical vibration,compared with the oocytes in meiosis I(MI)and meiosis II(MII)stages and zygotes.We analyzed the characteristics of mechanical vibrations of oocytes,including the amplitude as well as the frequency.It showed that the amplitude and frequency of nanomechanical vibrations induced by oocytes were caused by the cytoskeleton(microfilaments)and the distribution of metabolic characteristics(mitochondria)within oocytes.This work provides a new perspective for clinical quality assessment and basic research of oocytes,and can open new doors for development of life science. | Yongpei Peng Junhui Zhang Weiwei Xue Wenjie Wu Yu Wang Kainan Mei Ye Chen Depeng Rao Tianhao Yan Jianye Wang Yunxia Cao Shangquan Wu Qingchuan Zhang | 2023 | Nano Research2023,16,2: | 0 |
| 20 | Relay-type sensing mode:A strategy to push the limit on nanomechanical sensor sensitivity based on the magneto lever显示文摘Ultrasensitive molecular detection and quantization are crucial for many applications including clinical diagnostics,functional proteomics,and drug discovery;however,conventional biochemical sensors cannot satisfy the stringent requirements,and this has resulted in a long-standing dilemma regarding sensitivity improvement.To this end,we have developed an ultrasensitive relay-type nanomechanical sensor based on a magneto lever.By establishing the link between very weak molecular interaction and five orders of magnitude larger magnetic force,analytes at ultratrace level can produce a clearly observable mechanical response.Initially,proof-of-concept studies showed an improved detection limit up to five orders of magnitude when employing the magneto lever,as compared with direct detection using probe alone.In this study,we subsequently demonstrated that the relay-type sensing mode was universal in application ranging from micromolecule to macromolecule detection,which can be easily extended to detect enzymes,DNA,proteins,cells,viruses,bacteria,chemicals,etc.Importantly,we found that,sensitivity was no longer subject to probe affinity when the magneto lever was sufficiently high,theoretically,even reaching single-molecule resolution. | Depeng Rao Tianhao Yan Zihan Qiao Yu Wang Yongpei Peng Han Tu Shangquan Wu Qingchuan Zhang | 2023 | Nano Research2023,16,2: | 0 |
