2Chromosome-level genome of Himalayan yew provides insights into the origin and evolution of the paclitaxel biosynthetic pathway显示文摘Taxus,commonly known as yew,is a well-known gymnosperm with great ornamental and medicinal value.In this study,by assembling a chromosome-level genome of the Himalayan yew(Taxus wallichiana)with 10.9 Gb in 12 chromosomes,we revealed that tandem duplication acts as the driving force of gene family evolution in the yew genome,resulting in the main genes for paclitaxel biosynthesis,i.e.those encoding the taxadiene synthase,P450s,and transferases,being clustered on the same chromosome.The tandem duplication may also provide genetic resources for the nature to sculpt the core structure of taxoids at different positions and subsequently establish the complex pathway of paclitaxel by neofunctionalization.Furthermore,we confirmed that there are two genes in the cluster encoding isoenzymes of a known enzyme in the paclitaxel biosynthetic pathway.The reference genome of the Himalayan yew will serve as a platform for decoding the complete biosynthetic pathway of paclitaxel and understanding the chemodi-versity of taxoids in gymnosperms.Jian Cheng Xiao Wang Xiaonan Liu Xiaoxi Zhu Zihe Li Huanyu Chu Qian Wang QianQian Lou Bijun Cai Yiqun Yang Xiaoyun Lu Kai Peng Dingyu Liu Yuwan Liu Lina Lu Huan Liu Ting Yang Qijin Ge Chengcheng Shi Guichun Liu Zhiwei Dong Xun Xu Wen Wang Huifeng Jiang Yanhe Ma 2021Molecular Plant2021,14,7:6
3Monocyte chemoattractant protein-1 induces endothelial cell apoptosis in vitro through a p53-dependent mitochondrial pathway显示文摘cystinecystine (CC ) chemokine 单核白血球 chemoattractant protein-1 (MCP-1 ) 被建立了由于它领先的单核白血球的趋化性的能力在动脉粥样硬化的发展起一个病原的作用定位到 subendothelia。最近的研究揭示了除趋化性以外的更多的 MCP-1 功能。这里,我们报导 MCP-1 的各种各样的集中(0.1100 ng/ml ) 导致了人的脐的静脉 endothelial 房间(HUVEC ) 紧张 CRL-1730 apoptosis, caspase-9 激活,和几 mitochondrial 改变。而且, HUVEC 的 MCP-1 upregulated p53 表示和 p53 特定的禁止者 pifithrin-(PFT ) 救了 HUVEC 的 MCP-1-induced apoptosis。而且,激活或抑制可能也影响的 PKC (蛋白质 kinase C ) HUVEC apoptosis 由 MCP-1 导致了。这些调查结果一起证明 MCP-1 经由一条 p53 依赖的 mitochondrial 小径在 vitro 在 HUVEC 上施加直接 proapoptotic 效果。Xuan Zhang, Xiping Liu Huifeng Shang Yan Xu Minzhang Qian 2011Acta Biochimica et Biophysica Sinica2011,43,10:6
4Controlled growth of molecularly pure Au_(25) (SR)_(18) and Au_(38) (SR)_(24) nanoclusters from the same polydispersed crude product显示文摘We report the controlled growth of Au25(SR)18 and Au38 (SR)24 (where R = CH2CH2Ph) nanoclusters of molecular purity via size-focusing from the same crude product that contains a distribution of nanoclusters. In this method, gold salt was first mixed with tetraoctylammonium bromide (TOAB), and then reacted with excess thiol to form Au(I)-SR polymers in THF (as opposed to toluene in previous work), followed by NaBH 4 reduction. The resultant crude product contains polydisperse nanoclusters and was then used as the common starting material for controlled growth of Au25(SR)18 and Au38(SR)24 , respectively. In Route I, Au25(SR)18 nanoclusters of molecular purify were produced from the crude product after 6 h aging at room temperature. In Route II, the crude product was isolated and further subjected to thermal thiol etching in a toluene solution containing excess thiol, and one obtained pure Au38(SR)24 nanoclusters, instead of Au25(SR)18 . This work not only provides a robust and simple method to prepare both Au25(SR)18 and Au38(SR)24 nanoclusters, but also reveals that these two nanoclusters require different environments for the size-focusing growth process.QIAN HuiFeng LIU Chao JIN RongChao 2012Science China Chemistry2012,55,11:3

9pUGTdb:A comprehensive database of plant UDP-dependent glycosyltransferases显示文摘Dear Editor,Plant UDP-dependent glycosyltransferases(UGTs),belonging to the carbohydrate-active enzyme glycosyltransferase 1 family(Louveau and Osbourn,2019),not only play important roles in adaptation to various environments(Cai et al.,2020;Pastorczyk-Szlenkier and Bednarek,2021)but also endow plant natural products with great pharmaceutical and ecological significance(Margolin et al.,2020).In recent years,an increasing number of plant UGTs have been characterized to function in the biosynthesis of many bioactive compounds such as ginsenosides(Wei et al.,2015),breviscapine(Liu et al.,2018),and rubusoside(Xu et al.,2022).Yuqian Liu Qian Wang Xiaonan Liu Jian Chengi Lei Zhang Huanyu Chu Ruoyu Wang Haoran Li Hong Chang Nida Ahmed Zhonghua Wang Xiaoping Liao Huifeng Jiang 2023Molecular Plant2023,16,4:1

13PCPD:Plant cytochrome P450 database and web-based tools for structural construction and ligand docking显示文摘Plant cytochrome P450s play key roles in the diversification and functional modification of plant natural products.Although over 200,000 plant P450 gene sequences have been recorded,only seven crystalized P450 genes severely hampered the functional characterization,gene mining and engineering of important P450s.Here,we combined Rosetta homologous modeling and MD-based refinement to construct a high-resolution P450 structure prediction process(PCPCM),which was applied to 181 plant P450s with identified functions.Furthermore,we constructed a ligand docking process(PCPLD)that can be applied for plant P450s virtual screening.10 examples of virtual screening indicated the process can reduce about 80%screening space for next experimental verification.Finally,we constructed a plant P450 database(PCPD:http://gffzz90f9b80da1174166hkwk55q6w9vfq6qqc.ffgz.tsg.suse.edu.cn/),which includes the sequences,structures and functions of the 181 plant P450s,and a web service based on PCPCM and PCPLD.Our study not only developed methods for the P450-specific structure analysis,but also introduced a universal approach that can assist the mining and functional analysis of P450 enzymes.Hui Wang Qian Wang Yuqian Liu Xiaoping Liao Huanyu Chu Hong Chang Yang Cao Zhigang Li Tongcun Zhang Jian Cheng Huifeng Jiang 2021Synthetic and Systems Biotechnology2021,6,2:1

16An Analysis on the Improvement of the Housing Security System Based on Population Mobility显示文摘China's urban housing security system has developed for years. The dual division between registered population and migrant population in cities still exists. While local governments undertake responsibility of the housing security through intergovernmental duty division, it is not appropriate because housing security is a kind of national income redistribution that belongs to the central government. From the perspective of the population mobility, the article discusses the problems of the current housing security system, based on which it proposes three recommendations for improving the existing housing security system. First, we should make a distinction between the national income redistribution carried out by the central government and the public services provided by local governments. The responsibility and fi scal expenditure of the local, provincial, and central government should be clearly defined. Second, intergovernmental fiscal transfer payment should be designed according to the population mobility status. Third, the housing security system should protect the demands of the new generation of peasant workers and migrant families.Qi Huifeng Wang Weiqiang Qian Fang 2016China City Planning Review2016,25,4:0
17Origin and evolution of the main starch biosynthetic enzymes显示文摘Starch,a semi-crystalline energy storage form primarily found in plant plastids plays a crucial role in various food or no-food applications.Despite the starch biosynthetic pathway’s main enzymes have been characterized,their origin and evolution remained a subject of debate.In this study,we conducted the comprehensive phylogenetic and structural analysis of three types of starch biosynthetic enzymes:starch synthase(SS),starch branching enzyme(SBE)and isoamylase-type debranching enzyme(ISA)from 51,151 annotated genomes.Our findings provide valuable insights into the possible scenario for the origin and evolution of the starch biosynthetic pathway.Initially,the ancestor of SBE can be traced back to an unidentified bacterium that existed before the formation of the last eukaryotic common ancestor(LECA)via horizontal gene transfer(HGT).This transfer event likely provided the eukaryote ancestor with the ability to synthesize glycogen.Furthermore,during the emergence of Archaeplastida,one clade of SS was transferred from Deltaproteobacteria by HGT,while ISA and the other clade of SS originated from Chlamydiae through endosymbiosis gene transfer(EGT).Both these transfer events collectively contributed to the establishment of the original starch biosynthetic pathway.Subsequently,after the divergence of Viridiplantae from Rhodophyta,all three enzymes underwent multiple duplications and N-terminus extension domain modifications,resulting in the formation of functionally specialized isoforms and ultimately leading to the complete starch biosynthetic pathway.By shedding light on the evolutionary origins of key enzymes involved in the starch biosynthetic pathway,this study provides important insights into the evolutionary events of plants.Hong Chang Jie Bai Hejian Zhang Rong Huang Huanyu Chu Qian Wang Hao Liu Jian Cheng Huifeng Jiang 2023Synthetic and Systems Biotechnology2023,8,3:0
18Genetic Architecture of Childhood Kidney and Urological Diseases in China显示文摘Kidney disease is manifested in a wide variety of phenotypes,many of which have an important hereditary component.To delineate the genotypic and phenotypic spectrum of pediatric nephropathy,a multicenter registration system is being imple-mented based on the Chinese Children Genetic Kidney Disease Database(CCGKDD).In this study,all the patients with kidney and urological diseases were recruited from 2014 to 2020.Genetic analysis was conducted using exome sequencing for families with multiple affected individuals with nephropathy or clinical suspicion of a genetic kidney disease owing to early-onset or extrarenal features.The genetic diagnosis was confirmed in 883 of 2256(39.1%)patients from 23 provinces in China.Phenotypic profiles showed that the primary diagnosis included steroid-resistant nephrotic syndrome(SRNS,23.5%),glomerulonephritis(GN,32.2%),congenital anomalies of the kidney and urinary tract(CAKUT,21.2%),cystic renal disease(3.9%),renal calcinosis/stone(3.6%),tubulopathy(9.7%),and chronic kidney disease of unknown etiology(CKDu,5.8%).The pathogenic variants of 105 monogenetic disorders were identified.Ten distinct genomic disorders were identified as pathogenic copy number variants(CNVs)in 11 patients.The diagnostic yield differed by subgroups,and was highest in those with cystic renal disease(66.3%),followed by tubulopathy(58.4%),GN(57.7%),CKDu(43.5%),SRNS(29.2%),renal calcinosis/stone(29.3%)and CAKUT(8.6%).Reverse phenotyping permitted correct identification in 40 cases with clinical reassessment and unexpected genetic conditions.We present the results of the largest cohort of children with kidney disease in China where diagnostic exome sequencing was performed.Our data demonstrate the utility of family-based exome sequencing,and indicate that the combined analysis of genotype and phenotype based on the national patient registry is pivotal to the genetic diagnosis of kidney disease.Ye Fang Hua Shi Tianchao Xiang Jiaojiao Liu Jialu Liu Xiaoshan Tang Xiaoyan Fang Jing Chen Yihui Zhai Qian Shen Guomin Li Li Sun Yunli Bi Xiang Wang Yanyan Qian Bingbing Wu Huijun Wang Wenhao Zhou Duan Ma Jianhua Mao Xiaoyun Jiang Shuzhen Sun Ying Shen Xiaorong Liu Aihua Zhang Xiaowen Wang Wenyan Huang Qiu Li Mo Wang Xiaojie Gao Yubin Wu Fang Deng Ruifeng Zhang Cuihua Liu Li Yu Jieqiu Zhuang Qing Sun Xiqiang Dang Haitao Bai Ying Zhu Siguang Lu Bili Zhang Xiaoshan Shao Xuemei Liu Mei Han Lijun Zhao Yuling Liu Jian Gao Ying Bao Dongfeng Zhang Qingshan Ma Liping Zhao Zhengkun Xia Biao Lu Yulong Wang Mengzhun Zhao Jianjiang Zhang Shan Jian Guohua He Huifeng Zhang Bo Zhao Xiaohua LI Feiyan Wang Yufeng Li Hongtao Zhu Xinhui Luo Jinghai Li Jia Rao Hong Xu 2021Phenomics2021,1,3:0
