| 1 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |
| 2 | Comparative untargeted proteomic analysis of ADME proteins and tumor antigens for tumor cell lines显示文摘In the present study, total membrane proteins from tumor cell lines including HepG2, Hep3 B2,H226, Ovcar3 and N87 were extracted and digested with γLys C and trypsin. The resulting peptide lysate were pre-fractionated and subjected to untargeted quantitative proteomics analysis using a high resolution mass spectrometer. The mass spectra were processed by the Max Quant and the protein abundances were estimated using total peak area(TPA) method. A total of 6037 proteins were identified, and the analysis resulted in the identification of 2647 membrane proteins. Of those, tumor antigens and absorption,metabolism, disposition and elimination(ADME) proteins including UDP-glucuronosyltransferase,cytochrome P450, solute carriers and ATP-binding cassette transporters were detected and disclosed significant variations among the cell lines. The principal component analysis was performed for the cluster of cell lines. The results demonstrated that H226 is closely related with N87, while Hep3 B2 aligned with HepG2. The protein cluster of Ovcar3 was apart from that of other cell lines investigated. By providing for the first time quantitative untargeted proteomics analysis, the results delineated the expression profiles of membrane proteins. These findings provided a useful resource for selecting targets of choice for anticancer therapy through advancing data obtained from preclinical tumor cell line models to clinical outcomes. | Xiaomei Gu Qing Xiao Qian Ruan Yuezhong Shu Ashok Dongre Ramaswamy Iyer W.Griffith Humphreys Yurong Lai | 2018 | Acta Pharmaceutica Sinica B2018，8，2： | 3 |
| 3 | Assembly-enhanced triplet-triplet annihilation upconversion in the aggregation formed by Schiff-base Pt(Ⅱ) complex grafting-permethyl-β-CD and 9,10-diphenylanthracence dimer显示文摘Water-soluble triplet sensitizer with permethyl-β-cyclodextrin(PMCD)grafting on a Schiff-base Pt(II)complex(Pt-2),in which PMCD unit serves as a host for binding the acceptors and the Schiff-base Pt(II)complex serves as a triplet sensitizer,was synthesized to investigate the effect of supramolecular complexation and assembly on the triplet-triplet annihilation upconversion emission in water.9,10-Diphenylanthracence(DPA)carboxylate(A-1)and its dimer(A-2)in which two DPA carboxylate were covalently linked with an alkyl chain were synthesized as triplet acceptors which also play a role of guest molecules for PMCD.A-1 and A-2 showed high affinity with PMCD,and A-2 can readily aggregate in water and form micron sized assemblies due to the hydrophobic effect andπ-πstacking of anthracene core in A-2.The efficiency of TTA-UC was demonstrated to be enhanced by a synergistic effect of host-guest complexation of Pt-2 with A-2 and the self-aggregation of the acceptor A-2,which facilitated the energy transfer and energy fusion among donor and acceptor. | Hongxia Lai Ting Zhao Yurong Deng Chunyin Fan Wanhua Wu Cheng Yang | 2019 | Chinese Chemical Letters2019，30，11： | 1 |
| 4 | Recent advances in the translation of drug metabolism and pharmacokinetics science for drug discovery and development显示文摘Drug metabolism and pharmacokinetics(DMPK) is an important branch of pharmaceutical sciences.The nature of ADME(absorption,distribution,metabolism,excretion) and PK(pharmacokinetics) inquiries during drug discovery and development has evolved in recent years from being largely descriptive to seeking a more quantitative and mechanistic understanding of the fate of drug candidates in biological systems.Tremendous progress has been made in the past decade,not only in the characterization of physiochemical properties of drugs that influence their ADME,target organ exposure,and toxicity,but also in the identification of design principles that can minimize drug-drug interaction(DDI) potentials and reduce the attritions.The importance of membrane transporters in drug disposition,efficacy,and safety,as well as the interplay with metabolic processes,has been increasingly recognized.Dramatic increases in investments on new modalities beyond traditional small and large molecule drugs,such as peptides,oligonucleotides,and antibody-drug conjugates,necessitated further innovations in bioanalytical and experimental tools for the characterization of their ADME properties.In this review,we highlight some of the most notable advances in the last decade,and provide future perspectives on potential major breakthroughs and innovations in the translation of DMPK science in various stages of drug discovery and development. | Yurong Lai Xiaoyan Chu Li Di Wei Gao Yingying Guo Xingrong Liu Chuang Lu Jialin Mao Hong Shen Huaping Tang Cindy Q.Xia Lei Zhang Xinxin Ding | 2022 | Acta Pharmaceutica Sinica B2022，12，6： | 0 |
