| 1 | Biochemistry of mammalian ferritins in the regulation of cellular iron homeostasis and oxidative responses显示文摘Ferritin,an iron-storage protein,regulates cellular iron metabolism and oxidative stress.The ferritin structure is characterized as a spherical cage,inside which large amounts of iron are deposited in a safe,compact and bioavailable form.All ferritins readily catalyze Fe(II)oxidation by peroxides at the ferroxidase center to prevent free Fe(II)from participating in oxygen free radical formation via Fenton chemistry.Thus,ferritin is generally recognized as a cytoprotective stratagem against intracellular oxidative damage.The expression of cytosolic ferritins is usually regulated by iron status and oxidative stress at both the transcriptional and post-transcriptional levels.The mechanism of ferritin-mediated iron recycling is far from clarified,though nuclear receptor co-activator 4(NCOA4)was recently identified as a cargo receptor for ferritin-based lysosomal degradation.Cytosolic ferritins are heteropolymers assembled by H-and L-chains in different proportions.The mitochondrial ferritins are homopolymers and distributed in restricted tissues.They play protective roles in mitochondria where heme-and Fe/S-enzymes are synthesized and high levels of ROS are produced.Genetic ferritin disorders are mainly related to the L-chain mutations,which generally cause severe movement diseases.This review is focused on the biochemistry and function of mammalian intracellular ferritin as the major iron-storage and anti-oxidation protein. | Jianlin Zhang Xuehui Chen Juanji Hong Aifa Tang Yang Liu Ni Xie Guohui Nie Xiyun Yan Minmin Liang | 2021 | Science China(Life Sciences)2021，64，3： | 5 |
| 2 | Carbon-based nanozymes for biomedical applications显示文摘Nanozymes are nanomaterials with enzyme-like properties that have attracted significant interest owing to their capability to address the limitations of traditional enzymes such as fragility,high cost,and impossible mass production.Over the past decade,a broad variety of nanomaterials have been found to mimic the enzyme-like activity by engineering the active centers of natural enzymes or developing multivalent elements within nanostructures.Carbon nanomaterials with well-defined electronic and geometric structures have served as favorable surrogates of traditional enzymes by mimicking the highly evolved catalytic center of natural enzymes.In particular,by combining the unique electronic,optical,thermal,and mechanical properties,carbon nanomaterials-based nanozymes can offer a variety of multifunctional platforms for biomedical applications.In this review,we will introduce the enzymatic characteristics and recent advances of carbon nanozymes,and summarize their significant applications in biomedicine. | Hui Ding Bing Hu Bin Zhang Han Zhang Xiyun Yan Guohui Nie Minmin Liang | 2021 | Nano Research2021，14，3： | 4 |
| 3 | Recent advances in anisotropic two-dimensional materials and device applications显示文摘Two-dimensional(2D)materials,such as transition metal dichalcogenides(TMDs),black phosphorus(BP),MXene and borophene,have aroused extensive attention since the discovery of graphene in 2004.They have wide range of applications in many research fields,such as optoelectronic devices,energy storage,catalysis,owing to their striking physical and chemical properties.Among them,anisotropic 2D material is one kind of 2D materials that possess different properties along different directions caused by the intrinsic anisotropic atoms5 arrangement of the 2D materials,mainly including BP,borophene,low-symmetry TMDs(ReSe2 and ReSa)and group IV monochalcogenides(SnS,SnSe,GeS,and GeSe).Recently,a series of new devices has been fabricated based on these anisotropic 2D materials.In this review,we start from a brief introduction of the classifications,crystal structures,preparation techniques,stability,as well as the strategy to discriminate the anisotropic characteristics of 2D materials.Then,the recent advanced applications including electronic devices,optoelectronic devices,thermoelectric devices and nanomechanical devices based on the anisotropic 2D materials both in experiment and theory have been summarized.Finally,the current challenges and prospects in device designs,integration,mechanical analysis,and micro-/nano-fabrication techniques related to anisotropic 2D materials have been discussed.This review is aimed to give a generalized knowledge of anisotropic 2D materials and their current devices applications,and thus inspiring the exploration and development of other kinds of new anisotropic 2D materials and various novel device applications. | Jinlai Zhao Dingtao Ma Cong Wang Zhinan Guo Bin Zhang Jianqing Li Guohui Nie Ni Xie Han Zhang | 2021 | Nano Research2021，14，4： | 4 |
| 4 | Black phosphorus-based photothermal therapy with aCD47-mediated immune checkpoint blockade for enhanced cancer immunotherapy显示文摘Here,we describe a combination strategy of black phosphorus(BP)-based photothermal therapy together with anti-CD47 antibody(aCD47)-based immunotherapy to synergistically enhance cancer treatment.Tumour resistance to immune checkpoint blockades in most cancers due to immune escape from host surveillance,along with the initiation of metastasis through immunosuppressive cells in the tumour microenvironment,remains a significant challenge for cancer immunotherapy.aCD47,an agent for CD47/SIRPαaxis blockade,induces modest phagocytic activity and a low response rate for monotherapy,resulting in failures in clinical trials.We showed that BP-mediated ablation of tumours through photothermal effects could serve as an effective strategy for specific immunological stimulation,improving the inherently poor immunogenicity of tumours,which is particularly useful for enhancing cancer immunotherapy.BP in combination with aCD47 blockade activates both innate and adaptive immunities and promotes local and systemic anticancer immune responses,thus offering a synergistically enhanced effect in suppression of tumour progression and in inducing abscopal effects for inhibition of metastatic cancers.Our combination strategy provides a promising platform in which photothermal agents could help to enhance the therapeutic efficacy of immunotherapy. | Zhongjian Xie Minhua Peng Ruitao Lu Xiangying Meng Weiyuan Liang Zhongjun Li Meng Qiu Bin Zhang Guohui Nie Ni Xie Han Zhang Paras N.Prasad | 2020 | Light(Science & Applications)2020，9，1： | 3 |

| 8 | Inhibiting DNA methylation alleviates cisplatininduced hearing loss by decreasing oxidative stress-induced mitochondria-dependent apoptosis via the LRP1-PI3K/AKT pathway显示文摘Cisplatin-related ototoxicity is a critical side effect of chemotherapy and can lead to irreversible hearing loss.This study aimed to assess the potential effect of the DNA methyltransferase(DNMT)inhibitor RG108 on cisplatin-induced ototoxicity.Immunohistochemistry,apoptosis assay,and auditory brainstem response(ABR)were employed to determine the impacts of RG108 on cisplatin-induced injury in murine hair cells(HCs)and spiral ganglion neurons(SGNs).Rhodamine 123 and TMRM were utilized for mitochondrial membrane potential(MMP)assessment.Reactive oxygen species(ROS)amounts were evaluated by Cellrox green and Mitosox-red probes.Mitochondrial respiratory function evaluation was performed by determining oxygen consumption rates(OCRs).The results showed that RG108 can markedly reduce cisplatin induced damage in HCs and SGNs,and alleviate apoptotic rate by protecting mitochondrial function through preventing ROS accumulation.Furthermore,RG108 upregulated BCL-2 and downregulated APAF1,BAX,and BAD in HEI-OC1 cells,and triggered the PI3K/AKT pathway.Decreased expression of low-density lipoprotein receptor-related protein 1(LRP1)and high methylation of the LRP1 promoter were observed after cisplatin treatment.RG108 treatment can increase LRP1expression and decrease LRP1 promoter methylation.In conclusion,RG108 might represent a new potential agent for preventing hearing loss induced by cisplatin via activating the LRP1-PI3K/AKT pathway. | Yingzi He Zhiwei Zheng Chang Liu Wen Li Liping Zhao Guohui Nie Huawei Li | 2022 | Acta Pharmaceutica Sinica B2022，12，3： | 1 |
| 9 | Black phosphorus quantum dots as multifunctional nanozymes for tumor photothermal/catalytic synergistic therapy显示文摘Nanozymes are nanomaterials with enzyme-like properties that have attracted significant interest owing to their high stability,easy preparation,and tunable catalytic properties,especially in the field of cancer therapy.However,the unfavorable catalytic effects of nanozymes in the acidic tumor microenvironment have limited their applications.Herein,we developed a biomimetic erythrocyte membrane-camouflaged ultrasmall black phosphorus quantum dots(BPQDs)nanozymes that simultaneously exhibited an exceptional near-infrared(NIR)photothermal property and dramatically photothermal-enhanced glucose oxidase(GOx)-like activity in the acidic tumor microenvironment.We demonstrated the engineered BPQDs gave a photothermal conversion efficiency of 28.9%that could rapidly heat the tumor up to 50℃ while effectively localized into tumors via homing peptide iRGD leading after intravenously injection.Meanwhile,the significantly enhanced GOx-like activity of BPQDs under NIR irradiation was capable of catalytical generating massive toxic reactive oxygen species via using cellular glucose.By combining the intrinsic photothermal property and the unique photothermal-enhanced GOx-like catalytic activity,the developed BPQDs were demonstrated to be an effective therapeutic strategy for inhibiting tumor growth in vivo.We believe that this work will provide a novel perspective for the development of nanozymes in tumor catalytic therapy. | Hui Ding Daji Wang Haibing Huang Xiaozhu Chen Jie Wang Jinjie Sun Jianlin Zhang Lu Lu Beiping Miao Yanjuan Cai Kelong Fan Yongtian Lu Hongsong Dong Xiyun Yan Guohui Nie Minmin Liang | 2022 | Nano Research2022，15，2： | 1 |

| 11 | Two-dimensional tin diselenide nanosheets pretreated with an alkaloid for near-and mid-infrared ultrafast photonics显示文摘Two-dimensional(2D)tin diselenide(SnSe2),a novel layered material with excellent optical and electronic properties,has been extensively investigated in various promising applications,including photodetectors,optical switching,and ultrafast photonics.In this work,SnSe2 nanosheets have been obtained after pretreatment in an alkaloid,exhibiting high optical absorption and electron-enriched properties.Besides,the performances of the prepared SnSe2 in near-infrared(NIR)and mid-infrared(MIR)ultrafast photonics are presented.Notably,by employing the SnSe2-deposited microfiber device as a saturable absorber(SA)exhibiting typical nonlinear optical absorption properties,stable ultrashort pulses and rogue waves are realized in an erbium-doped fiber laser.Furthermore,the SnSe2-deposited SA device is also applied to a thulium-doped fiber laser to achieve stable ultrashort pulses.This study indicates that SnSe2 is expected to be a suitable candidate for ultrafast fiber lasers in the NIR and MIR regions. | Zhenhong Wang Bin Zhang Bing Hu Zhongjun Li Chunyang Ma Yu Chen Yufeng Song Han Zhang Jun Liu Guohui Nie | 2020 | Photonics Research2020，8，11： | 0 |
| 12 | Suggestions of management on emergency responses to epidemic outbreaks in outpatient or emergency departments of tertiary teaching hospitals显示文摘Background Patients infected with the alpha,beta,and delta strains of coronavirus disease 2019(COVID-19)usually exhibit fever,dry cough,nasal congestion,sore throat,loss of taste or smell,runny nose,conjunctivitis,fatigue,myalgia,diarrhea,and other symptoms,[1]while patients infected with the omicron strain present mild symptoms,including nasal discharge,sore throat,sneezing,headache,and cough.[2]Some patients deliberately conceal the relevant medical history,which makes it difficult to find in the pre-examination screening in outpatient or emer-gency departments.Outpatient and emergency buildings are usually linked to each other,and some older floors are poorly ventilated.Once patients with COVID-19 see a doctor in an out-patient or emergency building,especially patients infected with the omicron strain,an outbreak of the epidemic in a large area is easily possible. | Ming Wu Zhiye Fang Li Zeng Xiaohua Xie Jun Liao Lei Yang Wenping Zheng Lijie Ren Biqiang Zhou Jianyi Xiong Yong Xu Guohui Nie | 2022 | Journal of Intensive Medicine2022，2，3： | 0 |
| 13 | 低氧时miR-210对鼻咽癌细胞株CNE-1的细胞周期蛋白D1的调控机理(英文)显示文摘Objective: The aim of our study was to determine the underlying mechanism of miR-210 on regulation of the cell cycle in nasopharyngeal carcinoma cell line CNE-1, particularly through regulation of cyclin D1, under hypoxic conditions. Methods: The CNE-1 cell line was induced with hypoxia, and the expression levels of endogenic miR-210 and cyclin D1 were detected by real-time PCR and Western blotting. Next, the luciferase assay was used to confirm that cyclin D1 is a target gene for miR-210. Cell cycle and cell proliferation were detected in CNE-1 cells that were cultured under hypoxic conditions with either overexpression or knockout of miR-210 using flow cytometry and MTT assay, respectively. Results: Hypoxia induced the expression of miR-210, resulting in reduced mRNA and protein levels of cyclin D1 and repression of cyclin D1 in CNE-1 cells. Further analysis indicated that miR-210 directly binded to the 3'UTR of the cyclin D1 gene, thus regulated the expression of cyclin D1. The flow cytometry assay showed that, under hypoxic conditions, miR-210 blocked CNE-1 cells in the G1 phase, and miR-210 also inhibited the proliferation of CNE-1 cells. Conclusion: Under hypoxic conditions, miR-210 directly reduced the expression of cyclin D1, leading to CNE-1 cells blocked in G1 phase. | Xueshuang Mei Hongyi Hu Guohui Nie | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，7： | 0 |

| 15 | Rapid and sensitive detection of Epstein-Barr virus antibodies in nasopharyngeal carcinoma by chemiluminescence strips based on iron-porphyrin single atom nanozyme显示文摘The correlation between Epstein-Barr virus(EBV)infection and nasopharyngeal carcinoma(NPC)risk has been extensively researched.The continual monitoring of EBV-IgAs provides a promising approach of NPC screening in its early stage.In this study,we successfully synthesized a single-atom nanozyme(SANzyme)through the application of iron-porphyrin based metal organic framework(MOF-FeP).The MOF-FeP possesses precisely-defined electronic and geometric structures that accurately mimic highly-evolved catalytic site of natural peroxidase.The peroxidase-like activity of MOF-FeP enables it to catalyze the chemiluminescence of luminol substrate.By integrating MOF-FeP into a traditional strip,we created a rapid and highly-sensitive evaluation tool for detecting EBV-IgAs.Importantly,the MOF-FeP strip enables the simultaneous detection of three EBV-IgAs,greatly improving the accuracy of EBV-associated NPC screening.The sensitivities of the MOF-FeP strip(75.56%–93.30%)surpass those of current enzyme-linked immunosorbent assay(ELISA)methods(64.44%–82.22%).This test takes only 16 min to perform as opposed to the customary 1–2 h required for standard ELISA.Additionally,the MOF-FeP strip is suitable for whole blood samples,thereby significantly simplifying the sample preparation and detection process.In conclusion,the MOF-FeP strip combines the simplicity of traditional strip with the high catalytic activity of SANzyme.Our innovative MOF-FeP strip offers a new point-of-care strategy for EBV-IgAs detection,which is expected to markedly facilitate early screening for EBV-associated diseases. | Daji Wang Jie Wang Dan Liu Jiuyang He Meiying Wang Haibing Huang Guohui Nie Hui Ding Xiyun Yan | 2024 | Nano Research2024，17，3： | 0 |

| 17 | Inhibition of histone methyltransferase PRMT5 attenuates cisplatininduced hearing loss through the PI3K/Akt-mediated mitochondrial apoptotic pathway显示文摘This study aimed to evaluate the therapeutic potential of inhibiting protein arginine methyltransferase 5(PRMT5)in cisplatin-induced hearing loss.The effects of PRMT5 inhibition on cisplatin-induced auditory injury were determined using immunohistochemistry,apoptosis assays,and auditory brainstem response.The mechanism of PRMT5 inhibition on hair cell survival was assessed using RNA-seq and Cleavage Under Targets and Tagment-quantitative polymerase chain reaction(CUT&Tag-qPCR)analyses in the HEI-OC1 cell line.Pharmacological inhibition of PRMT5 significantly alleviated cisplatin-induced damage to hair cells and spiral ganglion neurons in the cochlea and decreased apoptosis by protecting mitochondrial function and preventing the accumulation of reactive oxygen species.CUT&Tag-qPCR analysis demonstrated that inhibition of PRMT5 in HEI-OC1 cells reduced the accumulation of H4R3me2s/H3R8me2s marks at the promoter region of the Pik3ca gene,thus activating the expression of Pik3ca.These findings suggest that PRMT5 inhibitors have strong potential as agents against cisplatininduced ototoxicity and can lay the foundation for further research on treatment strategies of hearing loss. | Zhiwei Zheng Benyu Nan Chang Liu Dongmei Tang Wen Li Liping Zhao Guohui Nie Yingzi He | 2023 | Journal of Pharmaceutical Analysis2023，13，6： | 0 |
