| 1 | Targeting ferroptosis suppresses osteocyte glucolipotoxicity and alleviates diabetic osteoporosis显示文摘Diabetic osteoporosis(DOP) is the leading complication continuously threatening the bone health of patients with diabetes. A key pathogenic factor in DOP is loss of osteocyte viability. However, the mechanism of osteocyte death remains unclear. Here, we identified ferroptosis, which is iron-dependent programmed cell death, as a critical mechanism of osteocyte death in murine models of DOP. The diabetic microenvironment significantly enhanced osteocyte ferroptosis in vitro, as shown by the substantial lipid peroxidation, iron overload, and aberrant activation of the ferroptosis pathway. RNA sequencing showed that heme oxygenase-1(HO-1) expression was notably upregulated in ferroptotic osteocytes. Further findings revealed that HO-1 was essential for osteocyte ferroptosis in DOP and that its promoter activity was controlled by the interaction between the upstream NRF2 and c-JUN transcription factors. Targeting ferroptosis or HO-1 efficiently rescued osteocyte death in DOP by disrupting the vicious cycle between lipid peroxidation and HO-1 activation, eventually ameliorating trabecular deterioration. Our study provides insight into DOP pathogenesis, and our results provide a mechanism-based strategy for clinical DOP treatment. | Yiqi Yang Yixuan Lin Minqi Wang Kai Yuan Qishan Wang Pei Mu Jingke Du Zhifeng Yu Shengbing Yang Kai Huang Yugang Wang Hanjun Li Tingting Tang | 2022 | Bone Research2022，10，3： | 19 |
| 2 | Single‑Atom Catalysts:Advances and Challenges in Metal‑Support Interactions for Enhanced Electrocatalysis显示文摘Single-atom catalysts(SACs),which contain a single metal atom supported on a well-confined substrate,are among the most promising heterogeneous catalysts owing to their unique advantages,such as high intrinsic activity and selectivity,tunable bonds and coordination,abundant metal-containing active sites,and atomic economy.Since metal-support interactions(MSIs)in SACs exert a substantial influence on the catalytic properties,gaining a profound understanding and recognition of catalytic reactions depends greatly on investigating MSIs both experimentally and computationally.Hence,the engineer-ing and modulation of MSIs are regarded as one of the most efficient methods to rationally design SACs with disruptively enhanced catalytic properties.In this review,we track the recent advances in SACs from an MSI perspective.We then discuss the existing MSIs in SACs and elucidate the significant role of strong MSIs in catalytic properties and mechanisms.The chal-lenges hindering the rational design of supported SACs with strong MSIs,which are currently still far from being completely understood and overcome,are described.In addition,the correlation between strong MSIs and electrocatalytic activities in SACs,including an outlook to increase our understanding of MSIs,is discussed.Finally,the present review provides some perspectives and an in-depth understanding of strong MSIs to advance high-performing SACs. | Yang Mu Tingting Wang Jian Zhang Changgong Meng Yifu Zhang Zongkui Kou | 2022 | Electrochemical Energy Reviews2022，5，1： | 3 |
| 3 | Downregulation of thioredoxin reductase 1 expression in the substantia nigra pars compacta of Parkinson's disease mice显示文摘Because neurons are susceptible to oxidative damage and thioredoxin reductase 1 is extensively distributed in the central nervous system and has antioxidant properties,we speculated that the enzyme may be involved in the pathogenesis of Parkinson’s disease.A Parkinson’s disease model was produced by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine into C57BL/6 mice.Real-time reverse transcription-PCR,western blot analysis and colorimetric assay showed that the levels of thioredoxin reductase 1 mRNA and protein were decreased,along with a significant reduction in thioredoxin reductase activity,in the midbrain of Parkinson’s disease mice compared with normal mice.Immunohistochemical staining revealed that the number of thioredoxin reductase 1-positive neurons in the substantia nigra pars compacta of Parkinson’s disease mice was significantly decreased compared with normal mice.These experimental findings suggest that the expression of thioredoxin reductase 1 in the substantia nigra pars compacta of Parkinson’s disease mice is significantly decreased,and that the enzyme may be associated with disease onset. | Zihua Liu Yuhong Jing Jie Yin Jiying Mu Tingting Yao Liping Gao | 2013 | Neural Regeneration Research2013，8，35： | 2 |
| 4 | Genetically modified CD7-targeting allogeneic CAR-T cell therapy with enhanced efficacy for relapsed/refractory CD7-positive hematological malignancies:a phase I clinical study显示文摘Chimeric antigen receptor(CAR)-T cell therapy against T cell malignancies faces major challenges including fratricide between CAR-T cells and product contamination from the blasts.Allogeneic CAR-T cells,generated from healthy donor T cells,can provide ready-to-use,blast-free therapeutic products,but their application could be complicated by graft-versus-host disease(GvHD)and host rejection.Here we developed healthy donor-derived,CD7-targeting CAR-T cells(RD13-01)with genetic modifications to resist fratricide,GvHD and allogeneic rejection,as well as to potentiate antitumor function.A phase I clinical trial(NCT04538599)was conducted with twelve patients recruited(eleven with T cell leukemia/lymphoma,and one with CD7-expressing acute myeloid leukemia).All patients achieved pre-set end points and eleven proceeded to efficacy evaluation.No dose-limiting toxicity,GvHD,immune effector cell-associated neurotoxicity or severe cytokine release syndrome(grade≥3)were observed.28 days post infusion,81.8%of patients(9/11)showed objective responses and the complete response rate was 63.6%(7/11,including the patient with AML).3 of the responding patients were bridged to allogeneic hematopoietic stem cell transplantation.With a median follow-up of 10.5 months,4 patients remained in complete remission.Cytomegalovirus(CMV)and/or Epstein-Barr virus(EBV)reactivation was observed in several patients,and one died from EBV-associated diffuse large B-cell lymphoma(DLBCL).Expansion of CD7-negative normal T cells was detected post infusion.In summary,we present the first report of a Phase I clinical trial using healthy donor-derived CD7-targeting allogeneic CAR-T cells to treat CD7^(+)hematological malignancies.Our results demonstrated the encouraging safety and efficacy profiles of the RD13-01 allogeneic CAR-T cells for CD7^(+)tumors. | Yongxian Hu Yali Zhou Mingming Zhang Houli Zhao Guoqing Wei Wengang Ge Qu Cui Qitian Mu Gong Chen Lu Han Tingting Guo Jiazhen Cui Xiaoyan Jiang Xiujun Zheng Shuhui Yu Xiaolong Li Xingwang Zhang Mingxi Chen Xiuju Li Ming Gao Kang Wang Cheng Zu Hao Zhang Xiaohong He Yanbin Wang Dongrui Wang Jiangtao Ren He Huang | 2022 | Cell Research2022，32，11： | 2 |

| 16 | Eupalinolide B inhibits hepatic carcinoma by inducing ferroptosis and ROS-ER-JNK pathway显示文摘Primary hepatic carcinoma is a common malignant tumor.The classic molecular targeted drug sorafenib is costly and is only effective for some patients.Therefore,it is of great clinical significance to search for new molecular targeted drugs.Eupalinolide B(EB)from Eupatorium lindleyanum DC.is used to treat chronic tracheitis in clinical practice.However,the role of EB in hepatic carcinoma is unknown.In this study,we first measure the effect of EB on tumor growth in a xenograft model and PDX model.The cell proliferation and migration are also detected in human hepatocarcinoma cell lines(SMMC-7721 and HCCLM3).Then,we investigate cell cycle,cell apoptosis,cell necrosis,cell autophagy,and ferroptosis by flow cytometry,western blot analysis and electron microscopy.The results demonstrate that EB exerts anti-proliferative activity in hepatic carcinoma by blocking cell cycle arrest at S phase and inducing ferroptosis mediated by endoplasmic reticulum(ER)stress,as well as HO-1 activation.When HO-1 is inhibited,EB-induced cell death and ER protein expression are rescued.The migration-related mechanism consists of activation of the ROS-ER-JNK signaling pathway and is not connected to ferroptosis.In summary,we first discover that EB inhibits cell proliferation and migration in hepatic carcinoma,and thus EB is a promising anti-tumor compound that can be used for hepatic carcinoma. | Yonghui Zhang Haoyang Zhang Jinage Mu Meiyue Han Zhihao Cao Feng Dong Tingting Wang Lian Pan Wujing Luo Jiaxin Li Huan Liu Lishan Jin Wenxuan Ding Yong Wei Xuesong Deng Dan Liu Xiuzhen He Yi Pang Xiao Mu Zhongjun Wu Dilong Chen | 2022 | Acta Biochimica et Biophysica Sinica2022，54，7： | 1 |

| 18 | Single-atom Fe Embedded Co_(3)S_(4) for Efficient Electrocatalytic Oxygen Evolution Reaction显示文摘Constructing atomically dispersed active sites with densely exposed and dispersed double metal-Sx catalytic sites for favorable OER catalytic activity remains rare and challenging.Herein,we design and construct a Fe_(1)S_(x)@Co_(3)S_(4) electrocatalyst with Fe single atoms epitaxially confined in Co_(3)S_(4) nanosheets for catalyzing the sluggish alkaline oxygen evolution reaction(OER).Consequently,in ultralow concentration alkaline solutions(0.1 mol/L KOH),such a catalyst is highly active and robust for OER with low overpotentials of 300 and 333 mV at current densities of 10 and 30 mA/cm^(2),respectively,accompanying long-term stability without significant degradation even for 350 h.In addition,Fe_(1)S_(x)@Co_(3)S_(4) shows a turnover frequency(TOF)value of 0.18 s−1,nearly three times that of Co_(3)S_(4)(0.07 s−1),suggesting the higher atomic utilization of Fe single atoms.Mössbauer and in-situ Raman spectra confirm that the OER activity of Fe_(1)S_(x)@Co_(3)S_(4) origins from a thin catalytic layer of Co(Fe)OOH that interacts with trace-level Fe species in the electrolyte,creating dynamically stable active sites.Combined with experimental characterizations,it suggests that the most active S-coordinated dual-metal site configurations are 2S-bridged(Fe-Co)S4,in which Co-S and Fe-S moieties are shared with two S atoms,which can strongly regulate the adsorption energy of reaction intermediates,accelerating the OER reaction kinetics. | QI Yuxue LI Tingting HU Yajie XIANG Jiahong SHAO Wenqian CHEN Wenhua MU Xueqin LIU Suli CHEN Changyun YU Min MU Shichun | 2022 | Chemical Research in Chinese Universities2022，38，5： | 0 |
| 19 | Reduced pigmentation and thyroid hormone disruption in zebrafish embryos caused by industrial sludge near Bohai Bay,China显示文摘In recent years,pollution caused by the discharge of industrial wastewater into Bohai Bay has posed a potential threat to the health of surrounding residents.Sludge was collected from the outlet of a factory that discharges effluent into Bohai Bay,and alcohol extracts of sludge(SE)were prepared.We confirmed by UPLC-MS/MS analysis that the SE contained PAHs,including fluorene,pyrene,and phenanthrene.Zebrafish embryos as animal models were exposed to 0.1,0.3,0.5,1 and 5 mg/mL SE from 2 to 4 h post-fertilization(hpf)until 120 hpf.The results showed that SE caused a concentration-dependent increase in mortality and a decrease in hatchability.We found that SE significantly reduced eye pigmentation and decreased the movement of embryos and larvae.In addition,SE decreased triiodothyronine(T3)content and down-regulated the mRNA expression of some thyroid hormone-related genes including TPO and Thrβ,and caused the up-regulation of Dio2 and Dio3 at 120 hpf.Exposure to three individual PAHs found in SE,namely fluorene,pyrene,and phenanthrene,caused morphological and transcriptional changes that were similar to those caused by SE exposure.These findings indicate that PAHs in SE can reduce the pigmentation of zebrafish,which may be related to the genetic changes associated with thyroid hormones,and that zebrafish eye pigmentation can be used as an indicator of PAHs exposure. | Wenjing Dong Xiaoyu Yin Chelimuge Qi Tingting Wei Lijia Wei Jingfeng Yang Jingli Mu Hiroki Teraoka Wu Dong | 2023 | Water Biology and Security2023，2，4： | 0 |
| 20 | Evaluation of Inocula and Packing Material for Acceleration of Start-Up in Biofilters显示文摘Several strategies with different combination of inocula and packing material were investigated to obtain the optimal start-up time and elimination capacity (EC) in toluene biofiltration. The inocula contained the activated sludge and toluene degrading bacteria, and the packing material consisted of different mixing ratios of peat and wood chips. A final toluene load of 21.2 g/(m3·h) was attained step by step in four parallel biofilters. A shortest start-up time of 15 days and a highest EC of 17.0 g/(m3·h) were observed in the biofilter B-4, which was inoculated with a special microbial consortium consisting of three strains of toluene degrading bacteria and was packed with the mixture of peat and wood chips at a ratio of 80:20 (w/w). These results indicated that inoculating pre-acclimatized microbes dramatically shortened the start-up time, and such a composition of packing material could maintain an appropriate environment (with the bed porosity and water content equating to 0.45 and 1.96, respectively) for the growth of dominant toluene degrading bacteria in the biofilter. | Li Chao Zhao Dongfeng Mu Guiqin Song Xiangning Zhang Tingting Liu Jun | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，2： | 0 |
