| 1 | Allosteric inhibition reveals SHP2-mediated tumor immunosuppression in colon cancer by single-cell transcriptomics显示文摘Colorectal cancer(CRC), a malignant tumor worldwide consists of microsatellite instability(MSI) and stable(MSS) phenotypes. Although SHP2 is a hopeful target for cancer therapy, its relationship with innate immunosuppression remains elusive. To address that, single-cell RNA sequencing wasperformed to explore the role of SHP2 in all cell types of tumor microenvironment(TME) from murine MC38 xenografts. Intratumoral cells were found to be functionally heterogeneous and responded significantly to SHP099, a SHP2 allosteric inhibitor. The malignant evolution of tumor cells was remarkably arrested by SHP099. Mechanistically, STING-TBK1-IRF3-mediated type I interferon signaling was highly activated by SHP099 in infiltrated myeloid cells. Notably, CRC patients with MSS phenotype exhibited greater macrophage infiltration and more potent SHP2 phosphorylation in CD68;macrophages than MSI-high phenotypes, suggesting the potential role of macrophagic SHP2 in TME. Collectively,our data reveals a mechanism of innate immunosuppression mediated by SHP2, suggesting that SHP2 is a promising target for colon cancer immunotherapy. | Jian Gao Zhigui Wu Mingxia Zhao Rui Zhang Manru Li Dongdong Sun Haibo Cheng Xianjia Qi Yuxian Shen Qiang Xu Hongqi Chen Dijun Chen Yang Sun | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 5 |
| 2 | Preparation of high concentration polyaluminum chloride with high content of Al_b or Al_c显示文摘A novel membrane distillation concentration method was used to prepare high concentration polyaluminum chloride (PACl) with high content of Alb or Alc. 2.52 mol/L PACl1 with 88% Alb and 2.38 mol/L PACl2 with 61% Alc were successfully prepared. Three coagulants, AlCl3, PACl1 and PACl2 were investigated on their hydrolysis behavior and speciation under different conditions. The effects of pH and dilution ratio on Al species distribution were investigated by ferron assay. Experimental result showed that pH had a significant effect on Al species distribution for the three coagulants. Dilution ratio had little effects on Alb and Alc distribution in whole dilution process except the beginning for PACl1 and PACl2. The results indicated that transformation of Al depends largely on their original composition. AlCl3 was the most unstable coagulant among these three coagulants during hydrolysis process. PACl1 and PACl2 with significant amounts of highly charged and stable polynuclear aluminum hydrolysis products were less affected by the hydrolysis conditions and could maintain high speciation stability under various conditions. | ZHAO Changwei ZHANG Jingbo LUAN Zhaokun PENG Xianjia REN Xiaojing | 2009 | Journal of Environmental Sciences2009，21，10： | 3 |
| 3 | A complete assembly of the rice Nipponbare reference genome显示文摘Dear Editor,In 2005,the current commonly used rice reference genome(Oryza sativa ssp.japonica cv.Nipponbare)was initially released by the International Rice Genome Sequencing Project(International Rice Genome Sequencing Project,2005).Thereafter,the reference genome was further updated in 2013 with improved genome assembly(IRGSP-1.0)and gene annotations(MSU7,RAP-DB)(Kawahara et al.,2013;Sakai et al.,2013).In the past 10 years,this reference has been serving as one of the most important genetic resources for subsequent rice functional genomics efforts.As several rice genomes had been assembled into gapless chromosomes with only 2–5 telomeres absent(Li et al.,2021;Song et al.,2021;Zhang et al.,2022),the IRGSP1.0 and its annotations still performed as the most widely used reference.However,limitations of sequencing technology and intricate genomic organization led to an under-representation of complex regions in this reference,leaving a total of 72 major gaps(including 19 telomeres),167 minor gaps,and 779 unknown bases(Kawahara et al.,2013),with an estimated length of3%of the genome unsolved. | Lianguang Shang Wenchuang He Tianyi Wang Yingxue Yang Qiang Xu Xianjia Zhao Longbo Yang Hong Zhang Xiaoxia Li Yang Lv Wu Chen Shuo Cao Xianmeng Wang Bin Zhang Xiangpei Liu Xiaoman Yu Huiying He Hua Wei Yue Leng Chuanlin Shi Mingliang Guo Zhipeng Zhang Bintao Zhang Qiaoling Yuan Hongge Qian Xinglan Cao Yan Cui Qianqian Zhang Xiaofan Dai Congcong Liu Longbiao Guo Yongfeng Zhou Xiaoming Zheng Jue Ruan Zhukuan Cheng Weihua Pan Qian Qian | 2023 | Molecular Plant2023，16，8： | 1 |
| 4 | Just-in-Time Human Gesture Recognition Using WiFi Signals显示文摘In-air gesture recognition using wireless signals acts as a key enabler for various applications including smart homes, remote healthcare, shared autopilot, etc. Although researchers have conducted extensive research on Wi Fi-based gesture recognition, it remains an open question of providing accurate, robust, and in-time recognition system with the commodity WiFi infrastructure. We present Fa See, a just-in-time Wi Fibased gesture recognition system by identifying the fine-grained Channel state information(CSI) features upon off-the-shelf WiFi devices. The core of Fa See is essentially a novel hybrid recognition algorithm, which combines the classical K-Means algorithm with Dynamic time warping(DTW) together, to transform the feature matching in traditional gesture recognition schemes into a hierarchical manner, thereby significantly improving the recognition efficiency. Experimental results show that Fa See recognizes 9 representative gestures with an average accuracy of 94.75% without tedious per-person training,while achieving 30% signal processing delay saving when compared with the state-of-the-arts gesture recognition schemes. | MENG Xianjia FENG Lin CHEN Hao CHEN Ting MA Jianfeng WANG Anwen LIU Dongdong ZHAO Yanfeng | 2021 | Chinese Journal of Electronics2021，30，6： | 1 |
| 5 | CIDP: a multi-functional platform for designing CRISPR sgRNAs显示文摘Dear Editor,Compared with traditional technologies affecting gene expression,changing DNA sequences of target genes is one of the most outstanding characters of CRISPR(Clustered Regularly Interspaced Short Palindromic Repeats).Single-guide RNAs(sgRNAs)guiding endonuclease Cas to target sites is a crucial step of CRISPR-Cas system for changing DNA sequences.An ideal sgRNA should only bind to the target gene.However,similar sequences of non-target sites can also be recognized leading to off-target effects[1]. | Dong Xu Jin Zhang Xianjia Zhao Yuze Hou Heling Jiang Wenchuang He Xiongfeng Ma Weihua Pan | 2023 | Horticulture Research2023，10，7： | 0 |
| 6 | Clean and effective removal of Cl(-I)from strongly acidic wastewater by PbO_(2)显示文摘Recycling strongly acidic wastewater as diluted H_(2)SO_(4) after contaminants contained being removed was previously proposed,however,Cl(-I),a kind of contaminant contained in strongly acidic wastewater,is difficult to remove,which severely degrades the quality of recycled H_(2)SO_(4).In this study,the removal of Cl(-I)using PbO_(2) was investigated and the involved mechanisms were explored.The removal efficiency of Cl(-I)reached 93.38%at 50℃ when PbO_(2)/Cl(-I)mole ratio reached 2:1.The identification of reaction products shows that Cl(-I)was oxidized to Cl_(2),and PbO_(2) was reduced to PbSO_(4).Cl_(2) was absorbed by NaOH to form NaClO,which was used for the regeneration of PbO_(2) from the generated PbSO_(4).Cl(-I)was removed through two pathways,i.e.,surface oxidation and•OH radical oxidation.•OH generated by the reaction of PbO_(2) and OH−plays an important role in Cl(-I)removal.The regenerated PbO_(2) had excellent performance to remove Cl(-I)after six-time regeneration.This study provided an in-depth understanding on the effective removal of Cl(-I)by the oxidation method. | Jinmin Zhao Linghao Kong Xingyun Hu Xianjia Peng | 2022 | Journal of Environmental Sciences2022，34，10： | 0 |
