| 3 | Lithium–matrix composite anode protected by a solid electrolyte layer for stable lithium metal batteries显示文摘Lithium (Li) metal with an ultrahigh specific theoretical capacity and the lowest reduction potential is strongly considered as a promising anode for high-energy-density batteries. However, uncontrolled lithium dendrites and infinite volume change during repeated plating/stripping cycles hinder its practical applications immensely. Herein, a house-like Li anode (housed Li) was designed to circumvent the above issues. The house matrix was composed of carbon fiber matrix and affords a stable structure to relieve the volume change. An artificial solid electrolyte layer was formed on composite Li metal, just like the roof of a house, which facilitates uniform Li ions diffusion and serves as a physical barrier against electrolyte corrosion. With the combination of solid electrolyte layer and matrix in the composite Li metal anode, both dendrite growth and volume expansion are remarkably inhibited. The housed Li|LiFePO4 batteries exhibited over 95% capacity retention after 500 cycles at 1.0 C in coin cell and 85% capacity retention after 80 cycles at 0.5 C in pouch cell. The rationally combination of solid electrolyte layer protection and housed framework in one Li metal anode sheds fresh insights on the design principle of a safe and long-lifespan Li metal anode for Li metal batteries. | Xin Shen Xinbing Cheng Peng Shi Jiaqi Huang Xueqiang Zhang Chong Yan Tao Li Qiang Zhang | 2019 | Journal of Energy Chemistry2019，28，10： | 23 |

| 7 | CRISPR/Cas9-mediated PINK1 deletion leads to neurodegeneration in rhesus monkeys显示文摘Dear Editor,PINK1 mutations cause autosomal recessive and early-onset Parkinson’s disease(PD)with selective neurodegeneration.Unfortunately,current PINK1 knockout(KO)mouse1,2 and pig models3,4 are unable to recapitulate the selective and overt neurodegeneration seen in PD patients.Furthermore,endogenous Pink1 in the mouse brain is expressed at very low levels and can only be detected via immunoprecipitation,5 meaning that PINK1’s function in the mammalian brain needs to be assessed using larger animals that are closer to humans.We previously used CRISPR/Cas9 to target the monkey gene in one-cell stage embryos.6 Using the same approach,we designed two gRNAs to target exon 2(T1)and exon 4(T2),which encode a kinase domain in the PINK1 gene of rhesus monkeys(Fig.1a).CRISPR/Cas9 and PINK1 gRNAs were injected into one-cell stage rhesus monkey embryos.A T7E1 assay and sequencing of PCR products from the injected embryos showed high efficiency(61.5%)in targeting PINK1(Fig.1b and Supplementary information,Fig.S1).Transfer of 87 embryos to 28 surrogate rhesus monkeys resulted in 11 pregnancies(39.2%)(Fig.1b).Eleven fetuses developed to term and were born naturally.Of these live monkeys,eight carried PINK1 mutations(M),and three were wild type(WT).However,three mutant monkeys(M1,M3 and M4)were newborn triplets that struggled to survive and died 3-4 days after birth.One WT newborn monkey also died after a difficult labor.Another mutant monkey(M2)died 7 days after birth without noticeable warning signs or symptoms.The other three mutant monkeys(M6,M7 and M8)have lived for three years;M5,however,reduced its food intake and showed weakness at the age of 1.5 years,and died 30 days after anesthesia for MRI examination. | Weili Yang Yunbo Liu Zhuchi Tu Chong Xiao Sen Yan Xishan Ma Xiangyu Guo Xiusheng Chen Peng Yin Zhengyi Yang Su Yang Tianzi Jiang Shihua Li Chuan Qin Xiao-Jiang Li | 2019 | Cell Research2019，29，4： | 12 |
| 8 | m^6A-dependent biogenesis of circular RNAs in male germ cells显示文摘The majority of circular RNAs(circRNAs)spliced from coding genes contain open reading frames(ORFs)and thus,have protein coding potential.However,it remains unknown what regulates the biogenesis of these ORF-containing circRNAs,whether they are actually translated into proteins and what functions they play in specific physiological contexts.Here,we report that a large number of circRNAs are synthesized with increasing abundance when late pachytene spermatocytes develop into round and then elongating spermatids during murine spermatogenesis.For a subset of circRNAs,the back splicing appears to occur mostly at m^6A-enriched sites,which are usually located around the start and stop codons in linear mRNAs.Consequently,approximately a half of these male germ cell circRNAs contain large ORFs with m^6A-modified start codons in their junctions,features that have been recently shown to be associated with protein-coding potential.Hundreds of peptides encoded by the junction sequences of these circRNAs were detected using liquid chromatography coupled with mass spectrometry,suggesting that these circRNAs can indeed be translated into proteins in both developing(spermatocytes and spermatids)and mature(spermatozoa)male germ cells.The present study discovered not only a novel role of m^6A in the biogenesis of coding circRNAs,but also a potential mechanism to ensure stable and long-lasting protein production in the absence of linear mRNAs,i.e.,through production of circRNAs containing large ORFs and m^6A-modified start codons in junction sequences. | Chong Tang Yeming Xie Tian Yu Na Liu Zhuqing Wang Rebekah J.Woolsey Yunge Tang Xinzong Zhang Weibing Qin Ying Zhang Ge Song Weiwei Zheng Juan Wang Weitian Chen Xiongyi Wei Zhe Xie Rachel Klukovich Huili Zheng David R.Quilici Wei Yan | 2020 | Cell Research2020，30，3： | 12 |

| 12 | A compact inorganic layer for robust anode protection in lithium-sulfur batteries显示文摘Lithium-sulfur(Li-S)batteries are one of the most promising candidates for high energy density rechargeable batteries beyond current Li-ion batteries.However,severe corrosion of Li metal anode and low Coulombic efficiency(CE)induced by the unremitting shuttle of Li polysulfides immensely hinder the practical applications of Li-S batteries.Herein,a compact inorganic layer(CIL)formed by ex situ reactions between Li anode and ionic liquid emerged as an effective strategy to block Li polysulfides and suppress shuttle effect.A CE of 96.7%was achieved in Li-S batteries with CIL protected Li anode in contrast to 82.4%for bare Li anode while no lithium nitrate was employed.Furthermore,the corrosion of Li during cycling was effectively inhibited.While applied to working batteries,80.6%of the initial capacity after 100 cycles was retained in Li-S batteries with CIL-protected ultrathin(33μm)Li anode compared with 58.5%for bare Li anode,further demonstrating the potential of this strategy for practical applications.This study presents a feasible interfacial regulation strategy to protect Li anode with the presence of Li polysulfides and opens avenues for Li anode protection in Li-S batteries under practical conditions. | Yu-Xing Yao Xue-Qiang Zhang Bo-Quan Li Chong Yan Peng-Yu Chen Jia-Qi Huang Qiang Zhang | 2020 | InfoMat2020，2，2： | 10 |
| 13 | Ferroptosis in cancer and cancer immunotherapy显示文摘The hallmark of tumorigenesis is the successful circumvention of cell death regulation for achieving unlimited replication and immortality.Ferroptosis is a newly identified type of cell death dependent on lipid peroxidation which differs from classical programmed cell death in terms of morphology,physiology and biochemistry.The broad spectrum of injury and tumor tolerance are the main reasons for radiotherapy and chemotherapy failure.The effective rate of tumor immunotherapy as a new treatment method is less than 30%.Ferroptosis can be seen in radiotherapy,chemotherapy,and tumor immunotherapy;therefore,fer-roptosis activation may be a potential strategy to overcome the drug resistance mechanism of traditional cancer treatments.In this review,the characteristics and causes of cell death by lipid peroxidation in ferroptosis are briefly described.In addition,the three metabolic regulations of ferroptosis and its crosstalk with classical signaling pathways are summarized.Collectively,these findings sug-gest the vital role of ferroptosis in immunotherapy based on the interaction of ferroptosis with tumor immunotherapy,chemotherapy and radiotherapy,thus,indicating the remarkable potential of ferroptosis in cancer treatment. | Lei Zhao Xiaoxue Zhou Feng Xie Lei Zhang Haiyan Yan Jun Huang Chong Zhang Fangfang Zhou Jun Chen Long Zhang | 2022 | Cancer Communications2022，42，2： | 10 |
| 14 | Clinical features of acute hepatitis E super-infections on chronic hepatitis B显示文摘AIM To examine the clinical features and risk factors for adverse outcomes in chronic hepatitis B(CHB) superimposed with hepatitis E virus(HEV).METHODS This retrospective cohort study included 228 patients with acute HEV infection(showing clinical acute hepatitis symptomology and positivity for anti-HEV immunoglobulin M) with underlying CHB(confirmed by positivity for hepatitis B surface antigen and/or hepatitis B virus(HBV) DNA over 6 mo) who had been admitted to the Shanghai Public Health Clinical Center, which represents the regional tertiary hospital for infectious diseases in Shanghai city, China. Data for adverse outcomes were collected, and included severe liver diseases(defined as liver failure and/or acute liver decompensation) and liver-related mortality. Logistic regression modeling was performed to determine the risk factors for adverse outcomes.RESULTS The symptoms caused by superimposed acute hepatitis E(AHE) were much more severe in cirrhotic patients(n = 94) than in non-cirrhotic patients(n = 134), as evidenced by significantly higher liver complications(77.7% vs 28.4%, P < 0.001) and mortality rate(21.3% vs 7.5%, P = 0.002). Most of the cirrhotic patients(n = 85, 90.4%) had no prior decompensation. Among the non-cirrhotic patients, superimposed AHE caused progressively more severe diseases that corresponded with the CHB disease stages, from immune tolerant to immune reactivation phases. Few risk factors were identified in the cirrhotic patients, but risk factors for non-cirrhotic patients were found to be intermediate HBV DNA levels(OR: 5.1, P = 0.012), alcohol consumption(OR: 6.4, P = 0.020), and underlying diabetes(OR: 7.5, P = 0.003) and kidney diseases(OR: 12.7, P = 0.005). Only 28.7% of the cirrhotic patients and 9.0% of the non-cirrhotic patients had received anti-HBV therapy previously and, in all cases, the efficacy had been suboptimal. CONCLUSION CHB-related cirrhosis and intermediate HBV DNA level were associated with severe disease in superinfected patients, and successful antiviral treatment might counter this outcome. | Chong Chen Shu-Ye Zhang Dan-Dan Zhang Xin-Yan Li Yu-Ling Zhang Wei-Xia Li Jing-Jing Yan Min Wang Jing-Na Xun Chuan Lu Yun Ling Yu-Xian Huang Liang Chen | 2016 | World Journal of Gastroenterology2016，22，47： | 10 |
| 15 | Lamivudine prophylaxis of liver allograft HBV reinfection in HBV related cirrhotic patients after liver transplantation显示文摘BACKGROUND: Liver allograft hepatitis B virus (HBV) reinfection and hepatitis B (HB) recurrence jeopardize the long-term survival of recipient and liver allograft. Lamivu- dine has been referred as a novel antiviral agent against HBV in HBV cirrhotic patients even in liver transplantation setting. We assessed the prophylatic effect of lamivudine on liver allograft HBV reinfection and clarified the dynamic changes of HBV markers in HBV related decompensated liver cirrhosis after liver transplantation. METHODS: Twenty-five recipients were divided into three groups: HBV active replication group (15 recipients), HBV inactive replication group (7), and control group (3). 100 mg/d lamivudine was administered preoperatively except in the control group. The HBV markers of serial sera and liver biopsy samples of the 25 recipients were evaluated re- gularly with enzyme-linked radioimmunoassay, HBV DNA fluorecent quantitative assay, immunohistochemical stain- ing , labelled streptavidin biotin ( LSAB) and digoxin la- belled HBV DNA hybridization in situ. The dynamic alter- nation of HBV markers under lamivudine prophylaxis was observed. RESULTS: In the HBV active replication group who had received lamivudine 2 weeks before liver transplantation, serum HBV DNA positive converted to negative by 80%. HBsAg of all recipients disappeared after liver transplanta- tion , but corresponding antibodies of HBV appeared within one week after the operation. HBsAb 9/15, HBcAb 13/15 and HBeAb 11/15 appeared and subsided gradually within 24 weeks. HBV DNA in sera was kept negative; HBsAg, HBcAg and HBV DNA hybridization in situ of liver biopsy samples remained negative after use of lamivudine. Ten of the 15 recipients showed clearance of HBV, and per se HBV markers were undetectable both in serum and liver bi- opsy samples between 12 to 44 weeks (24 weeks on ave- rage). The 1-, 2-year survival rates were 83% in this group. Two of the 15 recipients developed HBV allograft reinfection or recurrence of hepatitis 2 years after lamivudi- ne monoprophylaxis (2/15, 13.3%). In the HBV inactive replication group, the outcome was similar to that of the HBV active group. The HBV antibody frequency was HBs- Ab 4/7, HBcAb 6/7, and HBeAb 2/7. Three of 7 recipients showed HBV clearance both in sera and liver biopsy sam- ples , whereas in the control group all 3 recipients developed HBV allograft reinfection and recurrent hepatitis 8, 10, 12 months postoperatively; one of them died of fibrosing cho- lestatic hepatitis, and the remaining 2 recovered after addi- tional lamivudine therapy. The overall allograft reinfection rate was 9.1% (2/22) and the overall 1-, 2-year survival rates were 87%) in the lamivudine prophylaxis group. CONCLUSIONS: Lamivudine prophylaxis can prevent ef- fectively liver allograft from HBV reinfection in patients with HBV-related decompensated liver cirrhosis even in HBV active replication recipient after liver transplantation. Its long-term outcome remains to be studied. | Shi-Chun Lu, Lu-Nan Yan, Bo Li, Tian-Fu Wen, Ji-Chun Zhao, Nan-Sheng Cheng, Chong Liu, Jun Liu, Xiao-Bo Wang, Xiao-Dong Li, Shan Qin, Lian-Shan Zhao, Bin-Jun Lei and Xiu-Hui Zhang Chengdu, China Department of Surgery Viral Hepa- titis Research Center Department of Pathology , West China Hospital, Sichuan University, Cheng- du 610041 , China | 2004 | Hepatobiliary & Pancreatic Diseases International2004，3，1： | 9 |

| 17 | OsCIPK7 point-mutation leads to conformation and kinase-activity change for sensing cold response显示文摘Calcineurin B-like interacting protein kinases(CIPKs) play important roles via environmental stress.However, less is known how to sense the stress in molecular structure conformation level. Here, an Os CIPK7 mutant via TILLING procedure with a point mutation in the kinase domain showed increased chilling tolerance, which could be potentially used in the molecular breeding. We found that this point mutation of Os CIPK7 led to a conformationalchange in the activation loop of the kinase domain,subsequently with an increase of protein kinase activity,thus conferred an increased tolerance to chilling stress. | Dajian Zhang Xiaoyu Guo Yunyuan Xu Hao Li Liang Ma Xuefeng Yao Yuxiang Weng Yan Guo Chun-Ming Liu Kang Chong | 2019 | Journal of Integrative Plant Biology2019，61，12： | 8 |
| 18 | Sequential fate-switches in stem-like cells drive the tumorigenic trajectory from human neural stem cells to malignant glioma显示文摘Glioblastoma(GBM)is an incurable and highly heterogeneous brain tumor,originating from human neural stem/progenitor cells(hNSCs/hNPCs)years ahead of diagnosis.Despite extensive efforts to characterize hNSCs and end-stage GBM at bulk and single-cell levels,the de novo gliomagenic path from hNSCs is largely unknown due to technical difficulties in early-stage sampling and preclinical modeling.Here,we established two highly penetrant hNSC-derived malignant glioma models,which resemble the histopathology and transcriptional heterogeneity of human GBM.Integrating time-series analyses of whole-exome sequencing,bulk and single-cell RNA-seq,we reconstructed gliomagenic trajectories,and identified a persistent NSC-like population at all stages of tumorigenesis.Through trajectory analyses and lineage tracing,we showed that tumor progression is primarily driven by multi-step transcriptional reprogramming and fate-switches in the NSC-like cells,which sequentially generate malignant heterogeneity and induce tumor phenotype transitions.We further uncovered stage-specific oncogenic cascades,and among the candidate genes we functionally validated C1QL1 as a new glioma-promoting factor.Importantly,the neurogenic-to-gliogenic switch in NSC-like cells marks an early stage characterized by a burst of oncogenic alterations,during which transient AP-1 inhibition is sufficient to inhibit gliomagenesis.Together,our results reveal previously undercharacterized molecular dynamics and fate choices driving de novo gliomagenesis from hNSCs,and provide a blueprint for potential early-stage treatment/diagnosis for GBM. | Xiaofei Wang Ran Zhou Yanzhen Xiong Lingling Zhou Xiang Yan Manli Wang Fan Li Chuanxing Xie Yiming Zhang Zongyao Huang Chaoqiong Ding Kaidou Shi Weida Li Yu Liu Zhongwei Cao Zhen-Ning Zhang Shengtao Zhou Chong Chen Yan Zhang Lu Chen Yuan Wang | 2021 | Cell Research2021，31，6： | 8 |
| 19 | Integrated lithium metal anode protected by composite solid electrolyte film enables stable quasi-solid-state lithium metal batteries显示文摘Lithium(Li) metal,possessing an extremely high theoretical specific capacity(3860 mAh/g) and the most negative electrode potential(-3.040 V vs.standard hydrogen electrode),is one the most favorable anode materials for future high-energy-density batteries.However,the poor cyclability and safety issues induced by extremely unstable interfaces of traditional liquid Li metal batteries have limited their practical applications.Herein,a quasi-solid battery is constructed to offer superior interfacial stability as well as excellent interfacial contact by the incorporation of Li@composite solid electrolyte integrated electrode and a limited amount of liquid electrolyte(7.5 μL/cm2).By combining the inorganic garnet Aldoped Li6.75La3Zr1.75Ta0.25O12(LLZO) with high mechanical strength and ionic conductivity and the o rganic ethylene-vinyl acetate copolymer(EVA) with good flexibility,the composite solid electrolyte film could provide sufficient ion channels,sustained interfacial contact and good mechanical stability at the anode side,which significantly alleviates the thermodynamic corrosion and safety problems induced by liquid electrolytes.This innovative and facile quasi-solid strategy is aimed to promote the intrinsic safety and stability of working Li metal anode,shedding light on the development of next-generation highperformance Li metal batteries. | Junfan Ding Rui Xu Chong Yan Ye Xiao Yeru Liang Hong Yuan Jiaqi Huang | 2020 | Chinese Chemical Letters2020，31，9： | 8 |
| 20 | The Arabidopsis Spontaneous Cell Death1 gene, encoding a ζ-carotene desaturase essential for carotenoid biosynthesis, is involved in chloroplast development, photoprotection and retrograde signalling显示文摘Carotenoids, a class of natural pigments found in all photosynthetic organisms, are involved in a variety of physiologi-cal processes, including coloration, photoprotection, biosynthesis of abscisic acid (ABA) and chloroplast biogenesis.Although carotenoid biosynthesis has been well studied biochemically, the genetic basis of the pathway is not wellunderstood. Here, we report the characterization of two allelic Arabidopsis mutants, spontaneous cell death 1-1 (spcl-1)and spcl-2. The weak allele spcl-1 mutant showed characteristics of bleached leaves, accumulation of superoxide andmosaic cell death. The strong mutant allele spcl-2 caused a complete arrest of plant growth and development shortlyafter germination, leading to a seedling-lethal phenotype. Genetic and molecular analyses indicated that SPC1 encodesa putative ζ-carotene desaturase (ZDS) in the carotenoid biosynthesis pathway. Analysis of carotenoids revealed thatseveral major carotenoid compounds downstream of SPC1/ZDS were substantially reduced in spcl-1, suggesting thatSPC1 is a functional ZDS. Consistent with the downregulated expression of CAO and PORB, the chlorophyll contentwas decreased in spcl-1 plants. In addition, expression of Lhcb1.1, Lhcb1.4 and RbcS was absent in spcl-2, suggestingthe possible involvement of carotenoids in the plastid-to-nucleus retrograde signaling. The spcl-1 mutant also displaysan ABA-deficient phenotype that can be partially rescued by the externally supplied phytohormone. These results suggestthat SPC1/ZDS is essential for biosynthesis of carotenoids and plays a crucial role in plant growth and development. | Haili Dong Yan Deng Jinye Mu Qingtao Lu Yiqin Wang Yunyuan Xu Chengcai Chu Kang Chong Congming Lu Jianru Zuo | 2007 | Cell Research2007，17，5： | 8 |
