| 2 | Targeted mutagenesis in rice using CRISPR-Cpf1 system显示文摘Cpfl is a class 2/type V CRISPR effector that has been recently harnessed for genome editing(Zetsche et al.,2015;Hur et al.,2016;Kim et al.,2016).Cpfl recognizes thymidine-rich sequence as the protospacer-adjacent motif(PAM)at the 5'end of target sequences.In addition,Cpfl requires only a single shorter crRNA | Xixun Hu Chun Wang Qing Liu Yaping Fu Kejian Wang | 2017 | Journal of Genetics and Genomics2017，44，1： | 17 |
| 3 | Robust genome editing of CRISPR-Cas9 at NAG PAMs in rice显示文摘Dear Editor,The CRISPR-Cas9(clustered regularly interspaced short palindromic repeats/Cas9)system has been widely used for a variety of applications,including targeted gene knockout,gene insertion,gene replacement and base editing.Despite its wide use,the genome editing using CRISPR-Cas9 is performed almost exclusively at sites containing canonical NGG protospacer adjacent motifs(PAMs).To overcome the PAM constraint of the CRISPR-Cas9 system,many attempts have been made to develop various Cas9 orthologs | Xiangbing Meng Xixun Hu Qing Liu Xiaoguang Song Caixia Gao Jiayang Li Kejian Wang | 2018 | Science China(Life Sciences)2018，61，1： | 11 |
| 4 | Comparison of lymph node number and prognosis in gastric cancer patients with perigastric lymph nodes retrieved by surgeons and pathologists显示文摘Objective: To compare the numbers of positive and total lymph nodes and prognosis in gastric cancer patients whose perigastric lymph node retrieval was performed by surgeons and pathologists.Methods: We conducted a retrospective analysis of clinical and follow-up data from 1,056 patients who underwent gastric cancer D2 radical lymph node resection between January 2008 and December 2010 in the Gastrointestinal Surgery Department of Yantai Yuhuangding Hospital.The follow-up ended in December 2015.Patients were divided into two groups according to the specialty of physicians who performed the postoperative perigastric lymph node retrieval: the surgeon group(475 cases) and the pathologist group(581 cases).The numbers of positive and total perigastric lymph nodes and the 3- and 5-year survival were compared between gastric cancer patients in the two groups overall and stratified by TNM stage(AJCC 7th Edition).Results: Overall, the numbers of positive and total lymph nodes were significantly higher in the surgeon group than in the pathologist group(6.53±4.07 vs.4.09±3.70, P=0.021; 29.64±11.50 vs.20.71±8.56, P<0.001).Further analysis showed that the total number of lymph nodes in stage Ⅰ patients(19.40±9.62 vs.15.45±8.59, P=0.011) and the numbers of positive and total lymph nodes in stage Ⅱ(1.38±1.08 vs.0.87±1.55, P=0.031; 25.35±10.80 vs.16.75±8.56, P<0.001) and stage Ⅲ patients(8.11±6.91 vs.6.66±5.12, P=0.026; 32.34±12.55 vs.25.45±8.31, P<0.001)were significantly higher in the surgeon group than in the pathologist group.The survival analysis showed that the3- and 5-year survival of stage Ⅱ and Ⅲ patients was significantly higher in the surgeon group than in the pathologist group(82.0% vs.73.1%, 69.5% vs.61.2%, P=0.038; 49.2% vs.38.9%, 36.3% vs.28.0%; P=0.045).Conclusions: Compared with retrieval performed by pathologists, postoperative perigastric lymph node retrieval performed by surgeons was associated with significant increase in the total lymph node number of stage Ⅰ patients, the numbers of positive and total lymph nodes of stage Ⅱ and Ⅲ patients, and the survival of stage Ⅱ and stage Ⅲ gastric cancer patients. | Lixin Jiang Zengwu Yao Yifei Zhang Jinchen Hu Dawei Zhao Huiyuan Zhai Xixun Wang Zhenbin Zhang Dong Wang | 2016 | Chinese Journal of Cancer Research2016，28，5： | 5 |
| 5 | Cerebral Dopamine Neurotrophic Factor:A Potential Therapeutic Agent for Parkinson's Disease显示文摘The application of neurotrophic factors(NTFs)is a promising therapeutic strategy for neurodegenerative disorders such as Parkinson's disease(PD). Many NTFs have been reported to enhance the survival, regeneration,and differentiation of neurons and to induce synaptic plasticity. However, because of their potential side-effects and low efficacy after clinical administration, more potent treatments for neurodegenerative disorders are being sought. Cerebral dopamine neurotrophic factor(CDNF), a newly-identified NTF homologous to mesencephalic astrocyte-derived NTF, is structurally and functionally different from other NTFs, providing new hope especially for PD patients. In various animal models of PD, CDNF is efficient in protecting and repairing dopaminergic neurons,and it inhibits endoplasmic reticulum stress, neuroinflammation, and apoptosis. Recent progress in all facets of CDNF research has enabled researchers to better understand its beneficial effects in the treatment of PD. | Tingting Tang Yong Li Qian Jiao Xixun Du Hong Jiang | 2017 | Neuroscience Bulletin2017，33，5： | 4 |
| 6 | Development and Application of CRISPR/Cas System in Rice显示文摘In the past several years, the CRISPR(clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated protein) system has been harnessed as an efficient and powerful tool for targeted genome editing in different prokaryotic and eukaryotic species. Here, we review the development and application of CRISPR/Cas system in rice, emphasizing different varieties of CRISPR/Cas systems have been applied, strategies for multiplex editing, methods for precise gene insertion and replacement, and efficient systems for base editing and site-specific transcriptional regulation. In addition, the biosecurity of CRISPR/Cas system is also discussed, including transgene-free methods and off-target effects of CRISPR/Cas system. Thus, the development and application of CRISPR/Cas system will have significant impact on functional genomic research and variety improvement in rice. | REN Jun HU Xixun WANG Kejian WANG Chun | 2019 | Rice science2019，26，2： | 4 |

| 8 | Correlation of Ferroptosis and Other Types of Cell Death in Neurodegenerative Diseases显示文摘Ferroptosis is defined as an iron-dependent,non-apoptotic cell death pathway,with specific morphological phenotypes and biochemical changes.There is a growing realization that ferroptosis has significant implications for several neurodegenerative diseases.Even though ferroptosis is different from other forms of programmed death such as apoptosis and autophagic death,they involve a number of common protein molecules.This review focuses on current research on ferroptosis and summarizes the cross-talk among ferroptosis,apoptosis,and autophagy that are implicated in neurodegenerative diseases.We hope that this information provides new ideas for understanding the mechanisms and searching for potential therapeutic approaches and prevention of neurodegenerative diseases. | Xiaoting Dang Xuejie Huan Xixun Du Xi Chen Mingxia Bi Chunling Yan Qian Jiao Hong Jiang | 2022 | Neuroscience Bulletin2022，38，8： | 1 |

| 10 | Improving the efficiency of the CRISPR-Cas12a system with tRNA-crRNA arrays显示文摘CRISPR-Cas12a offers a convenient tool for multiplex genome editing in rice. However, the CRISPR-Cas12a system displays variable editing efficiency across genomic loci, with marked influence by CRISPR RNAs(crRNAs). To improve the efficiency of the CRISPR-Cas12a system for multiplex genome editing, we identified various architectures and expression strategies for crRNAs. Transformation of binary vectors loaded with engineered CRISPR-Cas12a systems into rice calli and subsequent sequencing revealed that a modified tRNA-crRNA array not only efficiently achieved rice multiplex genome editing, but also successfully edited target sites that were not edited by the crRNA array. This improvement contributes to the application of the CRISPR-Cas12a system in plant genome editing, especially for genomic loci that have hitherto been difficult to edit. | Xixun Hu Xiangbing Meng Jiayang Li Kejian Wang Hong Yu | 2020 | The Crop Journal2020，8，3： | 1 |
| 11 | Decomposition of Fast and Slow Cloud Responses to Quadrupled CO_(2)Forcing in BCC–AGCM2.0 over East Asia显示文摘In this study,the decomposed fast and slow responses of clouds to an abruptly quadrupled CO_(2)concentration(approximately 1139 ppmv)in East Asia(EA)are obtained quantitatively by using a general circulation model,BCC–AGCM2.0.Our results show that in the total response,the total cloud cover(TCC),low cloud cover(LCC),and high cloud cover(HCC)all increased north of 40°N and decreased south of 40°N except in the Tibetan Plateau(TP).The mean changes of the TCC,LCC,and HCC in EA were–0.74%,0.38%,and–0.38%in the total response,respectively;1.05%,–0.03%,and 1.63%in the fast response,respectively;and–1.79%,0.41%,and–2.01%in the slow response,respectively.By comparison,we found that changes in cloud cover were dominated by the slow response in most areas in EA due to the changes in atmospheric temperature,circulation,and water vapor supply together.Overall,the changes in the cloud forcing over EA related to the fast and slow responses were opposite to each other,and the final cloud forcing was dominated by the slow response.The mean net cloud forcing(NCF)in the total response over EA was–1.80 W m^(–2),indicating a cooling effect which partially offset the warming effect caused by the quadrupled CO_(2).The total responses of NCF in the TP,south China(SC),and northeast China(NE)were–6.74 W m^(–2),6.11 W m^(–2),and–7.49 W m^(–2),respectively.Thus,the local effects of offsetting or amplifying warming were particularly obvious. | Xixun ZHOU Bing XIE Hua ZHANG Jingyi HE Qi CHEN | 2022 | Advances in Atmospheric Sciences2022，39，12： | 0 |
| 12 | Expression and function of DMT1 without IRE in C6 cells mediated by recombinant adenovirus显示文摘Divalent metal transporter 1(DMT1)is a ferrous iron import protein.The improper expression of DMT1 is involved in neurodegenerative diseases.In the present study,we constructed a recombinant adenovirus containing the gene of DMT1 without the iron response element(DMT1-IRE)and investigated its expression and function in the C6 glioma cell line.The DMT1-IRE gene,obtained by RT-PCR,was cloned into the shuttle plasmid-ing pAdTrack-CMV containing greenfluorescent protein(GFP)reporter gene.Linearized plasmid pAdTrack-CMV-DMT1-IRE was subsequently co-transformed into Escher-ichia coli(E.coli)BJ5183 cells along with an adenoviral backbone plasmid pAdEasy-1 after digestion with Pme I.Pac I-digested pAdEasy1-DMT1-IRE was then transfected into E1-transformed human embryonic kidney cells(HEK293 cells),in which recombinant adenoviruses were generated within 7 to 10 days.The results demon-strated that we obtained the DMT1-IRE gene.pAdEasy1-DMT1-IRE yielded a large fragment,plus a smaller fragment of 4.5 kb after digestion with Pac I.PCR confirmed pAdEasy1-DMT1-IRE contained gene DMT1-IRE,indicating the successful construction of recombi-nant adenovirus plasmid containing DMT1-IRE.GFPfluorescence further confirmed the generation of recombi-nant AdDMT1-IRE adenovirus.AdDMT1-IRE could efficiently infect C6 glioma cells.And cell viability decreased in AdDMT1-IRE infected cells after iron overload compared to the control.These results suggest that the over expressed DMT1-IRE can aggravate the iron induced cell death due to its iron influx function. | Xixun DU Huamin XU Hong JIANG Jun WANG Lei WANG Junxia XIE | 2009 | Frontiers of Medicine2009，3，1： | 0 |
| 13 | A dural substitute based on oxidized quaternized guar gum/porcine peritoneal acellular matrix with improved stability, antibacterial and anti-adhesive properties显示文摘Trauma and neurosurgery often result in dural defects and are followed by serious complications or even death, finding suitable dural replacement materials to repair the defective dura has important clinical significance. Porcine peritoneal acellular matrix(PPAM) is a promising alternative material, but its poor stability makes it difficult to meet the various needs of dural reconstruction. In this work, we developed a novel antibacterial cross-linking agent oxidized quaternized guar gum(OQGG) and used it for the first time to stabilize PPAM to construct a dural mater substitute(OQGG-PPAM). The results showed that 1.5%OQGG-PPAM presented suitable mechanical property as well as good thermal stability and resistance to enzymatic degradation. It also exhibited good antibacterial activity and good anti-leakage ability. Furthermore, 1.5% OQGG-PPAM not only exhibited excellent cell compatibility but also significantly stimulated the secretion of b FGF and VEGF from seeded cells which was convenient for dural remodeling. In vivo experiment, it also exhibited the excellent histocompatibility and good anti-adhesion property. This study showed that OQGG can be used as a novel antibacterial cross-linking reagent for crosslinking natural tissues and 1.5% OQGG-PPAM was a potential candidate material for dura mater substitute. | Xiaoshuang Yu Pengfei Yue Xu Peng Hongmei Ding Ningning Lei Xixun Yu | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
