| 1 | Transmission Dynamics of an Outbreak of the COVID-19 Delta Variant B.1.617.2——Guangdong Province,China,May-June 2021显示文摘On May 21,2021,a local case of coronavirus disease 2019(COVID-19)was confirmed in a 75-year-old woman(experienced onset of symptoms on May 18)in Liwan District,Guangzhou City,Guangdong Province,China.The number of infections has increased in the following 10 days and led to 5 generations of transmission. | Meng Zhang Jianpeng Xiao Aiping Deng Yingtao Zhang Yali Zhuang Ting Hu Jiansen Li Hongwei Tu Bosheng Li Yan Zhou Jun Yuan Lei Luo Zimian Liang Youzhi Huang Guoqiang Ye Mingwei Cai Gongli Li Bo Yang Bin Xu Ximing Huang Yazun Cui Dongsheng Ren Yanping Zhang Min Kang Yan Li | 2021 | China CDC weekly2021，3，27： | 51 |
| 2 | GRAIN LENGTH AND AWN 1 negatively regulates grain size in rice显示文摘Grain size is an important factor determining yield in rice. Here, we identified a recessive mutant gene, grain length and awn 1 (gla1), which caused a significant increase in grain length and weight, and was associated with long awns. The gla1 mutation was mapped to a single-nucleotide polymorphism in a gene encoding a cytoplasmically-localized mitogen-activated protein kinase (MAPK) phosphatase. Overexpression of GLA1 caused a decrease in grain length, and the GLA1 protein interacted with OsMAPK6. These results suggest that GLA1 may serve as a negative regulator of the OsMAPKK4-OsMAPK6 cascade, controlling grain size via the dephosphorylation of OsMAPK6. | Tao Wang Ting Zou Zhiyuan He Guoqiang Yuan Tao Luo Jun Zhu Yueyang Liang Qiming Deng Shiquan Wang Aiping Zheng Huainian Liu Lingxia Wang Ping Li Shuangcheng Li | 2019 | Journal of Integrative Plant Biology2019，61，10： | 7 |
| 3 | The m^(6)A methylome of SARS-CoV-2 in host cells显示文摘The newly identified Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2)has resulted in a global health emergency because of its rapid spread and high mortality.The molecular mechanism of interaction between host and viral genomic RNA is yet unclear.We demonstrate herein that SARS-CoV-2 genomic RNA,as well as the negative-sense RNA,is dynamically N6-methyladenosine(m^(6)A)-modified in human and monkey cells.Combined RIP-seq and miCLIP analyses identified a total of 8 m^(6)A sites at single-base resolution in the genome.Especially,epidemic strains with mutations at these identified m^(6)A sites have emerged worldwide,and formed a unique cluster in the US as indicated by phylogenetic analysis.Further functional experiments showed that m^(6)A methylation negatively regulates SARS-CoV-2 infection.SARS-CoV-2 infection also triggered a global increase in host m^(6)A methylome,exhibiting altered localization and motifs of m^(6)A methylation in mRNAs.Altogether,our results identify m^(6)A as a dynamic epitranscriptomic mark mediating the virus–host interaction. | Jun’e Liu Yan-Peng Xu Kai Li Qing Ye Hang-Yu Zhou Hanxiao Sun Xiaoyu Li Liu Yu Yong-Qiang Deng Rui-Ting Li Meng-Li Cheng Bo He Jia Zhou Xiao-Feng Li Aiping Wu Chengqi Yi Cheng-Feng Qin | 2021 | Cell Research2021，31，4： | 5 |
| 4 | Less and shrunken pollen 1(LSP1) encodes a member of the ABC transporter family required for pollen wall development in rice(Oryza sativa L.)显示文摘Pollen fertility is an agronomic trait that strongly influences rice yield. Recent studies have revealed that the development of the pollen wall is required for pollen fertility and is regulated by several genes. However, the mechanisms underlying pollen and pollen wall development in rice remain largely unknown. In the present study, a point mutation in a gene on chromosome 1 was identified that resulted in the production of less and shrunken pollen(LSP) and led to defects in pollen wall formation. This gene was named LSP1 and was found to encode a member of the adenosine triphosphate-binding cassette(ABC)transporter G subfamily, OsABCG3. Two other loss-of-function mutants of LSP1/OsABCG3,generated using CRISPR/Cas9 technology, showed the same male sterile phenotype. The LSP1/OsABCG3 gene showed a spatio-temporal expression pattern in the developing anthers, and is an ortholog of the Arabidopsis genes At ABCG1 and At ABCG16, which play an important role in pollen wall development. Mutation of LSP1/OsABCG3 affected the expression of several genes involved in pollen and pollen wall formation. These results suggest that LSP1/OsABCG3 is critical for normal pollen fertility and shed light on the molecular mechanisms underlying rice pollen wall development. | Tao Luo Ting Zou Guoqiang Yuan Zhiyuan He Wenjie Li Yang Tao Miaomiao Liu Dan Zhou Hongfeng Zhao Jun Zhu Yueyang Liang Qiming Deng Shiquan Wang Aiping Zheng Huainian Liu Lingxia Wang Ping Li Shuangcheng Li | 2020 | The Crop Journal2020，8，3： | 4 |
| 5 | Comparison of Omicron and Delta Variant Infection COVID-19 Cases—Guangdong Province,China,2022显示文摘What is already known about this topic?The Omicron variant has been listed as a variant of concern,but the characteristics still remain unclear.What is added by this report?The vaccinated proportion of 65 imported coronavirus disease 2019 cases that were infected with Omicron variant in this study was 89.23%,which was higher than Delta cases.Most imported cases infected with Omicron were tested positive using polymerase chain reaction after entering Guangdong within 3 days,a shorter period than Delta. | Ting Hu Meng Zhang Aiping Deng Yingtao Zhang Bosheng Li Yan Li Min Kang | 2022 | China CDC weekly2022，4，18： | 3 |
| 6 | mTOR regulates TLR-induced c-fos and Th1 responses to HBV and HCV vaccines显示文摘Although IL-12 plays a critical role in priming Th1 and cytotoxic T lymphocyte(CTL) responses, Toll-like receptor(TLR) signaling only induces low amounts of IL-12 in dendritic cells and macrophages, implying the existence of stringent regulatory mechanisms. In this study, we sought to uncover the mechanisms underlying TLR-induced IL-12 expression and the Th1 response. By systemic screening, we identified a number of protein kinases involved in the regulation of TLRinduced IL-12 expression. In particular, PI3 K, ERK, and m TOR play critical roles in the TLR-induced Th1 response by regulating IL-12 and IL-10 production in innate immune cells. Moreover, we identified c-fos as a key molecule that mediates m TOR-regulated IL-12 and IL-10 expression in TLR signaling. Mechanistically, m TOR plays a crucial role in c-fos expression, thereby modulating NFκB binding to promoters of IL-12 and IL-10. By controlling the expression of a special innate gene program, m TOR can specifically regulate the TLR-induced T cell response in vivo. Furthermore, blockade of m TOR by rapamycin efficiently boosted TLR-induced antigen-specific T and B cell responses to HBV and HCV vaccines. Taken together, these results reveal a novel mechanism through which m TOR regulates TLR-induced IL-12 and IL-10 production, contributing new insights for strategies to improve vaccine efficacy. | Li He Aiping Zang Min Du Dapeng Ma Chuanping Yuan Chun Zhou Jing Mu Huanjing Shi Dapeng Li Xulin Huang Qiang Deng Jianhua Xiao Huimin Yan Lijian Hui Ke Lan Sidong Xiong Xiaoxia Li Zhong Huang Hui Xiao | 2015 | Virologica Sinica2015，30，3： | 2 |
| 7 | First Imported Case of SARS-CoV-2 Omicron Subvariant BA.2.12.1-Guangdong Province,China,April 30,2022显示文摘On April 23,2022,an international flight KQ880 from Nairobi,Kenya arrived at Guangzhou Baiyun International Airport,Guangzhou City,Guangdong Province.All passengers were transferred to the quarantine hotel for routine 14-day medical observation and regularly tested of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)nucleic acid.One of the patients,a 27-year-old Chinese male,reported positive SARS-CoV-2 nucleic acid on April 27,2022.The patient had a history of full coronavirus disease 2019(COVID-19)vaccination and denied exposure to other COVID-19 cases in the past 14 days.After diagnosis,he was transferred to Guangzhou Eighth People’s Hospital for treatment. | Lijun Liang Xiang Zhao Aiping Deng Kuibiao Li Jiajun Liu Fangzhu Ouyang Qianfang Guo Jing Xu Shen Huang Lirong Zou Yang Song Kai Nie Baisheng Li | 2022 | China CDC weekly2022，4，31： | 2 |
| 8 | Self-immolative micellar drug delivery:The linker matters显示文摘Redox-responsive polymer-drug conjugate micelles are excellent nanoscale vehicles for self-immolative intracellular drug delivery.To covalently connect the polymer and drug,disulfide-bearing linkers,such as 3,3'-dithiodipropionic acid (DDPA) and 4,4'-dithiodibutyric add (DDBA),are used.In this paper,we report the influence of linker length on the therapeutic outcome of redox-sensitive conjugate micelles.Curcumin was selected as the model drug and it was conjugated to a multivalent methoxy poly(ethylene glycol)-polylysine copolymer with DDPA or DDBA as the linker.The obtained two polymer-curcumin conjugates were amphiphilic and could self-assemble into micelles that have a hydrodynamic diameter less than 100 nm.The loading of curcumin in both micelles was above 20% (w/w).Irrespective of the linker type,micelle disassembly was observed due to the collapse of the disulfide bond in a reducing environment.However,the rate of curcumin release was much faster with the DDBA linker than with the DDPA linker as the side product was a 5-membered ring with a low ring strain.The linker length-induced variation of curcumin release kinetics caused a significant difference in the intracellular drug concentration and a higher cytotoxicity was witnessed in three model cell lines (HeLa,PC3,and 4T1) for the micelles with a DDBA linker compared to those containing a DDPA linker.As expected,this phenomenon was also observed in HeLa tumor-bearing nude mice in vivo.The current work highlights the significance of linker length in engineering redox-responsive on-demand delivery systems. | Xuan Meng Min Gao Jian Deng Di Lu Aiping Fan Dan Ding Deling Kong Zheng Wang Yanjun Zhao | 2018 | Nano Research2018，11，12： | 2 |

| 15 | Observation of Transcription Regulation in the Mouse Heart Nuclear DNA Fragments and the Specific-protein Interaction by AFM显示文摘Using atom force microscopy (AFM), in vitro transcription, PAGE and other experimental technologies, it is observed that, in active genes of mice (Balb/c) nuclear DNA fragments of non-transcriptional state, only regulation sequences at both ends are associated with scaffold proteins (indissociable proteins) and some transcriptional factors such as complexes (dissociable proteins) made of gene-coding proteins and specific auxiliary small molecules, while there are no combining proteins in intermediate coding sequences. However, in active genes of transcriptional state, both regulation sequences and intermediate coding sequences are associated with active transcriptional factors by non-covalent bonds.This paper shows the prospective application of AFM observation and in vitro transcription in the research on gene expression and regulation. It also offers some theoretical basis for localization of specific genes in human genomes. | 袁明秀 Ren Zhong Zheng Fei Deng Aiping Li Jianwei | 2003 | High Technology Letters2003，9，1： | 0 |

| 19 | A unique binding pocket induced by a noncanonical SAH mimic to develop potent and selective PRMT inhibitors显示文摘Protein arginine methyltransferases(PRMTs)are attractive targets for developing therapeutic agents,but selective PRMT inhibitors targeting the cofactor SAM binding site are limited.Herein,we report the discovery of a noncanonical but less polar SAH surrogate YD1113 by replacing the benzyl guanidine of a pan-PRMT inhibitor with a benzyl urea,potently and selectively inhibiting PRMT3/4/5.Importantly,crystal structures reveal that the benzyl urea moiety of YD1113 induces a unique and novel hydrophobic binding pocket in PRMT3/4,providing a structural basis for the selectivity.In addition,YD1113 can be modified by introducing a substrate mimic to form a“T-shaped”bisubstrate analogue YD1290 to engage both the SAM and substrate binding pockets,exhibiting potent and selective inhibition to typeⅠPRMTs(IC_(50)<5 nmol/L).In summary,we demonstrated the promise of YD1113 as a general SAH mimic to build potent and selective PRMT inhibitors. | Youchao Deng Xiaosheng Song Iredia D.Iyamu Aiping Dong Jinrong Min Rong Huang | 2023 | Acta Pharmaceutica Sinica B2023，13，12： | 0 |
| 20 | Dynamical analysis of diversity lump solutions to the(2+1)-dimensional dissipative Ablowitz-Kaup-Newell-Segure equation显示文摘The lump solution is one of the exact solutions of the nonlinear evolution equation.In this paper,we study the lump solution and lump-type solutions of(2+1)-dimensional dissipative Ablowitz-Kaup-Newell-Segure(AKNS)equation by the Hirota bilinear method and test function method.With the help of Maple,we draw three-dimensional plots of the lump solution and lump-type solutions,and by observing the plots,we analyze the dynamic behavior of the(2+1)-dimensional dissipative AKNS equation.We find that the interaction solutions come in a variety of interesting forms. | Hongcai Ma Yidan Gao Aiping Deng | 2022 | Communications in Theoretical Physics2022，74，11： | 0 |
