| 1 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021，8，3： | 3 |
| 2 | Enhancement of α-ketoisovalerate production by relieving the product inhibition of L-amino acid deaminase from Proteus mirabilis显示文摘L-Amino acid deaminase(LAAD) is a key enzyme in the deamination of L-valine(L-val) to produce α-ketoisovalerate(KIV). However, the product inhibition of LAAD is a major hindrance to industrial KIV production.In the present study, a combination strategy of modification of flexible loop regions around the product binding site and the avoidance of dramatic change of main-chain dynamics was reported to reduce the product inhibition.The four mutant PM-LAAD^(M4)(PM-LAAD^(S98A/T105A/S106A/L341A)) achieved a 6.2-fold higher catalytic efficiency and an almost 6.7-fold reduction in product inhibition than the wild-type enzyme. Docking experiments suggested that weakened interactions between the product and enzyme, and the flexibility of the 'lid' structure relieved LAAD product inhibition. Finally, the whole-cell biocatalyst PM-LAAD^(M4) has been applied to KIV production,the titer and conversion rate of KIV from L-val were 98.5 g·L^-1 and 99.2% at a 3-L scale, respectively. These results demonstrate that the newly engineered catalyst can significantly reduce the product inhibition, that making KIV a prospective product by bioconversion method, and also provide the understanding of the mechanism of the relieved product inhibition of PM-LAAD. | Shanshan Pei Xiaobo Ruan Jia Liu Wei Song Xiulai Chen Qiuling Luo Liming Liu Jing Wu | 2020 | Chinese Journal of Chemical Engineering2020，28，8： | 2 |

| 4 | A high-resolution cell atlas of the domestic pig lung and an online platform for exploring lung single-cell data显示文摘The genetically engineered pig is regarded as an optimal source of organ transplantation for humans and an excellent model for human disease research,given its comparable physiology to human beings.A myriad of single-cell RNA sequencing(sc RNA-seq)data on humans has been reported,but such data on pigs are scarce.Here,we apply sc RNA-seq technology to study the cellular heterogeneity of 3-month-old pig lungs,generating the single-cell atlas of 13,580 cells covering 16 major cell types.Based on these data,we systematically characterize the similarities and differences in the cellular cross-talk and expression patterns of respiratory virus receptors in each cell type of pig lungs compared with human lungs.Furthermore,we analyze pig lung xenotransplantation barriers and reported the cell-type expression patterns of 10 genes associated with pig-to-human immunobiological incompatibility and coagulation dysregulation.We also investigate the conserved transcription factors(TFs)and their candidate target genes and constructed five conserved TF regulatory networks in the main cell types shared by pig and human lungs.Finally,we present a comprehensive and openly accessible online platform,Scdb Lung.Our sc RNA-seq atlas of the domestic pig lung and Scdb Lung database can guide pig lung research and clinical applicability. | Lijing Zhang Jiacheng Zhu Haoyu Wang Jun Xia Ping Liu Fang Chen Hui Jiang Qiuling Miao Weiying Wu Lingli Zhang Lihua Luo Xiaosen Jiang Yong Bai Chengcheng Sun Dongsheng Chen Xingliang Zhang | 2021 | Journal of Genetics and Genomics2021，48，5： | 1 |

| 6 | Design,Synthesis,and Applications of ortho-Sulfur Substituted Arylphosphanes显示文摘Ortho-sulfur substituted arylphosphine oxides and arylphosphonates are the precursors of orthosulfurated arylphosphanes,which are widely utilized as ligands in transition metal-catalyzed reactions.However,efficient synthetic methods to access such compounds are sparse.Herein,highly valuable ortho-sulfur substituted arylphosphine oxides and arylphosphonates were constructed via difunctionalization of aryne precursors with P(O)H and elemental sulfur.This method avoids the use of transition metal catalysts and corrosive phosphorus chloride.The synthetic utility of this reaction is further demonstrated by the reduction of the synthesized products to access monophosphine ligands and their applications in cross-coupling reactions.Moreover,by introducing an alkyne moiety into the P(O)H substrate,cyclic sulfur-containing phosphines could be obtained in a one-pot reaction,which represents a new P,S structure that is inaccessible by known strategies. | Yu Guo Ying Luo Shiqiang Mu Jianke Su Jian Xu Qiuling Song | 2023 | CCS Chemistry2023，5，6： | 0 |
