2Diversity characterization and association analysis of agronomic traits in a Chinese peanut (Arachis hypogaea L.) mini-core collection显示文摘Association mapping is a powerful approach for exploring the molecular basis of phenotypic variations in plants.A peanut(Arachis hypogaea L.)mini-core collection in China comprising 298 accessions was genotyped using 109 simple sequence repeat(SSR)markers,which identified 554 SSR alleles and phenotyped for 15 agronomic traits in three different environments,exhibiting abundant genetic and phenotypic diversity within the panel.A model-based structure analysis assigned all accessions to three groups.Most of the accessions had the relative kinship of less than 0.05,indicating that there were no or weak relationships between accessions of the mini-core collection.For 15 agronomic traits in the peanut panel,generally the Q t K model exhibited the best performance to eliminate the false associated positives compared to the Q model and the general linear model-simple model.In total,89SSR alleles were identified to be associated with 15 agronomic traits of three environments by the Q t K model-based association analysis.Of these,eight alleles were repeatedly detected in two or three environments,and 15 alleles were commonly detected to be associated with multiple agronomic traits.Simple sequence repeat allelic effects confirmed significant differences between different genotypes of these repeatedly detected markers.Our results demonstrate the great potential of integrating the association analysis and marker-assisted breeding by utilizing the peanut mini-core collection.Huifang Jiang Li Huang Xiaoping Ren Yuning Chen Xiaojing Zhou Youlin Xia Jiaquan Huang Yong Lei Liying Yan Liyun Wan Boshou Liao 2014Journal of Integrative Plant Biology2014,56,2:14
3Low-dose decitabine enhances the effect of PD-1 blockade in colorectal cancer with microsatellite stability by re-modulating the tumor microenvironment显示文摘PD-1 blockade has demonstrated impressive clinical outcomes in colorectal cancers that have high microsatellite instability.However,the therapeutic efficacy for patients with tumors with low microsatellite instability or stable microsatellites needs further improvement.Here,we have demonstrated that low-dose decitabine could increase the expression of immune-related genes such as major histocompatibility complex genes and cytokine-related genes as well as the number of lymphocytes at the tumor site in CT26 colorectal cancer-bearing mice.A more significant inhibition of tumor growth and a prolongation of survival were observed in the CT26 mouse model after treatment with a combination of PD-1 blockade and decitabine than in mice treated with decitabine or PD-1 blockade alone.The anti-tumor effect of the PD-1 blockade was enhanced by low-dose decitabine.The results of RNA sequencing and whole-genome bisulfite sequencing of decitabine-treated CT26 cells and tumor samples with microsatellite stability from the patient tumor-derived xenograft model have shown that many immune-related genes,including antigen-processing and antigen-presenting genes,were upregulated,whereas the promoter demethylation was downregulated after decitabine exposure.Therefore,decitabine-based tumor microenvironment re-modulation could improve the effect of the PD-1 blockade.The application of decitabine in PD-1 blockade-based immunotherapy may elicit more potent immune responses,which can provide clinical benefits to the colorectal cancer patients with low microsatellite instability or stable microsatellites.Ganjun Yu Yanfeng Wu Wenying Wang Jia Xu Xiaoping Lv Xuetao Cao Tao Wan 2019Cellular & Molecular Immunology2019,16,4:14
4Wavy PtCu alloy nanowire networks with abundant surface defects enhanced oxygen reduction reaction显示文摘Bimetalic platinum-copper(Pt-Cu)alloy nanowires have emerged as a novel class of fuel cell electrocatalysts for oxygen reduction reaction(ORR)due to their intrinsic high catalytic activity and durability,but preparing such electrocatalysts with clean surface via facile method is still a challenge.Herein,PtCu alloy with nanowire networks(NWNs)structure is obtained by a simple modified polyol method accompanied with a salt-mediated self-assembly process in a water/ethylene glycol(EG)mixing media.The formation mechanism of PtCu NWNs including the morphological evolution and the relevant experimental parameters has been investigated systematically.We propose that a micro-interface in H2O-EG media formed with the assistance of disodium dihydrogen pyrophosphate(Na2H2P2O7)and its unique nature of coordinating with Pt^2+ or Cu^2+ play critical roles in the formation of NWNs.When tested as ORR catalyst,the PtCuNWNs/C exhibits much higher activity and durability than that of PtNWNs/C and commercial PtC,even exceeding the target of DOE in 2020.The excellent performance of PtCuNWNs/C could be attributed to the unique structure of NWNs with 2.4 nm ultrathin wavy nanowires and plentiful surface defects and the modified electronic effect caused by alloying with Cu atoms.Dahui Fang Lei Wan Qike Jiang Hongjie Zhang Xuejun Tang Xiaoping Qin Zhigang Shao Zidong Wei 2019Nano Research2019,12,11:4
5Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC.Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 2022Hepatobiliary Surgery and Nutrition2022,11,2:4
6p190A inactivating mutations cause aberrant RhoA activation and promote malignant transformation via the Hippo-YAP pathway in endometrial cancer显示文摘The Rho family of GTPases is strictly regulated by a large family of GTPase-activating proteins(GAPs)that stimulate the relatively weak intrinsic GTP-hydrolyzing activity of Rho GTPases.p190A is a potent and widely expressed GAP that acts on RhoA GTPases.p190A is frequently mutated in endometrial cancer,but the contribution of p190A mutations to endometrial tumorigenesis remains unclear.Here we identified that p190A is an upstream regulator of the Hippo-YAP signaling pathway,which is a critical regulator of cell proliferation,apoptosis,and cell fate.p190A knockout in endometrial cancer cells promoted cell proliferation,migration,and epithelial–mesenchymal transition(EMT),which were partially dependent on YAP activation.Wild-type p190A,but not endometrial cancer-associated mutants,suppressed the nuclear localization,transcriptional activity,and malignant transformation function of YAP.Moreover,the nuclear localization of YAP was enhanced in p190A-mutated endometrial cancer.These findings reveal novel molecular mechanisms underlying Hippo-YAP pathway-driven endometrial tumorigenesis and elucidate the potential for therapy targeting the Hippo-YAP pathway in p190A-mutated endometrial cancer.Xiaoli Wen Jing Wan Qizhi He Mengfei Wang Shuangdi Li Mei Jiang Zhen Qian Binya Liu Wen Lu Kai Wang Kun Gao Xiaoping Wan 2020Signal Transduction and Targeted Therapy2020,5,1:3
7Genetic diversity of atoxigenic Aspergillus flavus isolates from peanut kernels in China显示文摘Aflatoxin contamination in peanuts is a major threat to public health, especially in tropical and subtropical regions of the world. Recently, the use of atoxigenic Aspergillus flavus strains as biological control agents prove to be effective in reducing aflatoxin contamination in crops. A total of 208 atoxigenic A. flavus isolates, collected from peanut kernels, were grouped into 7 deletion patterns by quadruplex PCR products of nor-1, ver-1, aflR and omtA genes. 49 SNPs, found in 1254 bp fragment of omtA gene, showed genetic variation of omtA among different A. flavus isolates. These isolates were assigned to either MAT1-1 type or MAT1-2 type with primers for each MAT locus. Thus, rich genetic diversity was found in the atoxigenic A. flavus isolates of peanut in China. The results indicated that quadruplex PCR would be an effective method for rapid screening of atoxigenic isolates with gene deletion in aflatoxin biosynthetic cluster.Liying Yan Yanping Kang Yong Lei Liyun Wan Dongxin Huai Huifang Jiang Xiaoping Ren Boshou Liao 2018Oil Crop Science2018,3,1:2
8Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection显示文摘Sensitive and fast detection of neutrons and gamma rays is vital for homeland security,high-energy physics,and proton therapy.Fast-neutron detectors rely on light organic scintillators,andγ-ray detectors use heavy inorganic scintillators and semiconductors.Efficient mixed-field detection using a single material is highly challenging due to their contradictory requirements.Here we report hybrid perovskites(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)that combine light organic cations and heavy inorganic skeletons at a molecular level to achieve unprecedented performance for mixed-field radiation detection.High neutron absorption due to a high density of hydrogen,strong radiative recombination within the highly confined[PbX_(6)]^(4-)layer,and sub-nanometer distance between absorption sites and radiative centers,enable a light yield of 41000 photons/MeV,detection pulse width of 2.97 ns and extraordinary linearity response toward both fast neutrons andγ-rays,outperforming commonly used fast-neutron scintillators.Neutron energy spectrum,time-of-flight based fast-neutron/γ-ray discrimination and neutron yield monitoring were all successfully achieved using(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)detectors.We further demonstrate the monitoring of reaction kinetics and total power of a nuclear fusion reaction.We envision that molecular hybridized scintillators open a new avenue for mixed-field radiation detection and imaging.Mengling Xia Guangda Niu Linyue Liu Runlong Gao Tong Jin Pengying Wan Weicheng Pan Xianpeng Zhang Zuoxiang Xie Sam Teale Zenghua Cai Jiajun Luo Shan Zhao Haodi Wu Shiyou Chen Zhiping Zheng Qingguo Xie Xiaoping Ouyang Edward HSargent Jiang Tang 2022InfoMat2022,4,9:2

17In-Situ FT-IR Investigation Methane to Syngas over of Partial Oxidation of Rh/SiO2 Catalyst显示文摘Partial oxidation of methane to syngas(POM)over Rh/SiO_2 catalyst was investigated using in-situ FT-IR.When methane interacted with 1.0wt%Rh/SiO_2 catalyst,it was dissociated to adsorbed hydrogen and CH_x species.The adsorbed hydrogen atoms were transferred to SiO_2 surface by'spill-over'and reacted with lattice oxygen to form surface -OH species. POM mechanism was investigated over Rh/SiO_2 catalyst using in-situ FT-IR.It was found that CO_2 was formed before CO could be detected when CH_4 and O_2 were introduced over the preoxidized Rh/SiO_2 catalyst,whereas CO was detected before CO_2 was formed over the prereduced Rh/SiO_2 catalyst.Tinghua Wu Dongmin Lin Ying Wu Xiaoping Zhou Qiangu Yan Weizheng Weng Huilin Wan 2007Journal of Natural Gas Chemistry2007,16,3:1
18Identification of major QTL for seed number per pod on chromosome A05 of tetraploid peanut(Arachis hypogaea L.)显示文摘The inheritance of pod-and seed-number traits(PSNT) in peanut(Arachis hypogaea L.) is poorly understood. In the present study, a recombinant inbred line(RIL) population of 188 lines was used to map quantitative trait loci(QTL) for number of seeds per pod(NSP),number of pods per plant(NPP), and numbers of one-, two-, and three-seeded pods per plant(N1 PP, N2 PP, and N3 PP) in four environments. A total of 28 consensus QTL and 14 single QTL were identified, including 11 major and stable QTL. Four major and stable QTL including qN3 PPA5.2, q N3 PPA5.4, qN3 PPA5.5, and qN3 PPA5.7 each explained 12.3%–33.0% of phenotype variation. By use of another integrated linkage map for the A5 group(hereafter referred to as INT A5 group), QTL for PSNT were located in seven intervals of 0.73–9.68 Mb in length on chromosome A05, and candidate genes underlying N3 PP were suggested. These findings shed light on the genetic basis of PSNT. Major QTL for N3 PP could be used as candidates for further positional cloning.Yuning Chen Zhihui Wang Xiaoping Ren Li Huang Jianbin Guo Jiaojiao Zhao Xiaojing Zhou Liying Yan Huaiyong Luo Nian Liu Weigang Chen Liyun Wan Yong Lei Boshou Liao Dongxin Huai Huifang Jiang 2019The Crop Journal2019,7,2:1
