| 1 | The effects of claudin 14 during early Wallerian degeneration after sciatic nerve injury显示文摘Claudin 14 has been shown to promote nerve repair and regeneration in the early stages of Wallerian degeneration(0–4 days) in rats with sciatic nerve injury, but the mechanism underlying this process remains poorly understood. This study reported the effects of claudin 14 on nerve degeneration and regeneration during early Wallerian degeneration. Claudin 14 expression was up-regulated in sciatic nerve 4 days after Wallerian degeneration. The altered expression of claudin 14 in Schwann cells resulted in expression changes of cytokines in vitro. Expression of claudin 14 affected c-Jun, but not Akt and ERK1/2 pathways. Further studies revealed that enhanced expression of claudin 14 could promote Schwann cell proliferation and migration. Silencing of claudin 14 expression resulted in Schwann cell apoptosis and reduction in Schwann cell proliferation. Our data revealed the role of claudin 14 in early Wallerian degeneration, which may provide new insights into the molecular mechanisms of Wallerian degeneration. | Leilei Gong Yun Zhu Xi Xu Huaiqin Li Weimin Guo Qin Zhao Dengbing Yao | 2014 | Neural Regeneration Research2014,9,24: | 7 |

| 3 | miR-20a Promotes the Axon Regeneration of DRG Neurons by Targeting Nr4a3显示文摘Dear Editor,The peripheral nervous system(PNS)regenerates more easily after injury than the central nervous system(CNS)[1].Sensory neurons in the L4–L6 dorsal root ganglia(DRGs)extend axons to form the sciatic nerve along with motor axons.The DRG neuron is one of the exceptional mature neurons whose axons can regenerate after injury. | Lili Zhao Leilei Gong Ping Li Jing Qin Lingchi Xu Qiyao Wei Huimin Xie Susu Mao Bin Yu Xiaosong Gu Songlin Zhou | 2021 | Neuroscience Bulletin2021,37,4: | 3 |
| 4 | Phase stability and thermal conductivity of ytterbia and yttria co-doped zirconia显示文摘Rare earth oxides doping has been extensively investigated as one of the effective methods to lower thermal conductivity of 4.55 mol% Y2O3stabilized ZrO2(YSZ) thermal barrier coatings(TBCs).In the present work,5–6 mol% Yb2O3and Y2O3co-doped ZrO2ceramics were synthesized by solid reaction sintering at 1600 1C.The phase stability of the samples after heat treatment at 1500 1C was investigated.Yb2O3and Y2O3co-doped zirconia,especially when Yb2O3/Y2O3≥1,contained less monoclinic phase than single Yb2O3or Y2O3phase doped zirconia,indicating that co-doped zirconia was more stable at high temperature than YSZ.The thermal conductivity of the 3 mol% Yb2O3+3 mol% Y2O3co-doped ZrO2was 1.8 W m 1K 1at 1000 1C,which was more than 20% lower than that of YSZ. | Leilei Sun Hongbo Guo Hui Peng Shengkai Gong Huibin Xu | 2013 | Progress in Natural Science:Materials International2013,23,4: | 3 |
| 5 | Glucose-responsive erythrocyte-bound nanoparticles for continuously modulated insulin release显示文摘Glucose-responsive closed-loop insulin delivery systems represent a promising treatment strategy for diabetes,but current systems generally cannot achieve long-term effects.In this study,we designed an erythrocyte-biomimetic glucose-responsive system(EGRS)by coupling glucose-responsive nanoparticles(GRNs)to red blood cells;these nanoparticles exhibited the dual functions of glucose-responsiveness and persistent presence in circulation.GRNs are generated by encapsulating with insulin through ion crosslinking,followed by coloading with glucose oxidase(GOx)and catalase(CAT),a process that endows the nanoparticles with glucose-responsiveness.Simultaneously,the GRNs are coupled with red blood cells to camouflage them from the immune system,therefore,these erythrocyte-coupled GRNs can circulate in the blood for a long time.Under conditions of hyperglycemia,GOx acts on blood glucose to produce gluconic acid,which causes the rupture of GRNs and efficient release of insulin.Conversely,insulin is only released at the basic rate during hypoglycemia.Thus,EGRS can efficiently and continuously respond to hyperglycemia to maintain blood glucose levels within the normal range. | Xiaomin Xu Yani Xu Yuai Li Min Li Leilei Wang Qiang Zhang Bingjie Zhou Qing Lin Tao Gong Xun Sun Zhirong Zhang Ling Zhang | 2022 | Nano Research2022,15,6: | 2 |

| 7 | Developmental Temporal Patterns and Molecular Network Features in the Transcriptome of Rat Spinal Cord显示文摘The molecular network features of spinal cord development that are integral to tissue engineering remain poorly understood in placental mammals,especially in terms of their relationships with vital biological processes such as regeneration.Here,using a large-scale temporal transcriptomic analysis of rat spinal cord from the embryonic stage to adulthood,we show that fluctuating RNA expression levels reflect highly active transcriptional regulation,which may initiate spinal cord patterning.We also demonstrate that microRNAs(miRNAs)and transcriptional factors exhibit a mosaic profile based on their expression patterns,while differential alternative splicing events reveal that alternative splicing may be a driving force for the development of the node of Ranvier.Our study also supports the existence of a negative correlation between innate immunity and intrinsic growth capacity.Epigenetic modifications appear to perform their respective regulatory functions at different stages of development,while guanine nucleotidebinding protein(G protein)-coupled receptors(including olfactory receptors(ORs))may perform pleiotropic roles in axonal growth.This study provides a valuable resource for investigating spinal cord development and complements the increasing number of single-cell datasets.These findings also provide a genetic basis for the development of novel tissue engineering strategies. | Jian Yang Lili Zhao Sheng Yi Fei Ding Yumin Yang Yan Liu Yongjun Wang Mei Liu Chengbin Xue Lian Xu Leilei Gong Xinghui Wang Yu Zhang Bin Yu Guo-li Ming Xiaosong Gu | 2021 | Engineering2021,7,11: | 0 |
| 8 | Endogenous nucleotide as drug carrier:base-paired guanosine-5’-monophosphate:pemetrexed vesicles with enhanced anticancer capability显示文摘Endogenous substance such as nucleotide as a drug carrier has been proposed as a novel drug delivery system.The nucleotide guanosine-5’-monophosphate(GMP) is used to transport an anticancer drug pemetrexed disodium heptahydrate(PMX) via specific base pairing.The endogenous nature of GMP helps to avoid biocompatibility issues that are generally accompanied with nanocarriers including cytotoxicity,immunogenicity and blood compatibility.Furthermore,the low-molecular weight of the GMP nucleotide carrier significantly boosts the drug loading capacity compared to traditional liposomes and high-molecular weight carriers.Hydrogen-bonding interaction between the carrier and drug realizes the controlled release of loaded drug,and also facilitates large scale manufacture since no additional chemical synthesis is required.More importantly,in vivo experiments reveal that the base-paired GMP:PMX nanovesicles improve the target specificity and pharmacokinetic properties of PMX,and exhibit remarkably enhanced anticancer abilities compared to standalone PMX without any carriers.We envision that this strategy could be extended to other endogenous substances and drugs bearing functional groups capable of specific interaction,and promote the construction of drug delivery systems with inherent biocompatibility,enhanced drug delivery efficacy,and a simplified preparation method. | Lei Xu Chunyang Yu Dali Wang Ji Pang Leilei Shi Yue Su Lidong Gong Deyue Yan Xinyuan Zhu | 2020 | Science China Chemistry2020,63,2: | 0 |
| 9 | Spatiotemporal Dynamics of the Molecular Expression Pattern显示文摘Nerve regeneration in adult mammalian spinal cord is poor because of the lack of intrinsic regeneration of neurons and extrinsic factors–the glial scar is triggered by injury and inhibits or promotes regeneration.Recent technological advances in spatial transcriptomics(ST)provide a unique opportunity to decipher most genes systematically throughout scar formation,which remains poorly understood.Here,we frst constructed the tissue-wide gene expression patterns of mouse spinal cords over the course of scar formation using ST after spinal cord injury from 32 samples.Locally,we profled gene expression gradients from the leading edge to the core of the scar areas to further understand the scar microenvironment,such as neurotransmitter disorders,activation of the pro-infammatory response,neurotoxic saturated lipids,angiogenesis,obstructed axon extension,and extracellular structure re-organization.In addition,we described 21 cell transcriptional states during scar formation and delineated the origins,functional diversity,and possible trajectories of subpopulations of fbroblasts,glia,and immune cells.Specifcally,we found some regulators in special cell types,such as Thbs1 and Col1a2 in macrophages,CD36 and Postn in fbroblasts,Plxnb2 and Nxpe3 in microglia,Clu in astrocytes,and CD74 in oligodendrocytes.Furthermore,salvianolic acid B,a blood–brain barrier permeation and CD36 inhibitor,was administered after surgery and found to remedy fbrosis.Subsequently,we described the extent of the scar boundary and profled the bidirectional ligand-receptor interactions at the neighboring cluster boundary,contributing to maintain scar architecture during gliosis and fbrosis,and found that GPR37L1_PSAP,and GPR37_PSAP were the most signifcant gene-pairs among microglia,fbroblasts,and astrocytes.Last,we quantifed the fraction of scar-resident cells and proposed four possible phases of scar formation:macrophage infltration,proliferation and diferentiation of scar-resident cells,scar emergence,and scar stationary.Together,these profles delineated the spatial heterogeneity of the scar,confrmed the previous concepts about scar architecture,provided some new clues for scar formation,and served as a valuable resource for the treatment of central nervous system injury. | Leilei Gong Yun Gu Xiaoxiao Han Chengcheng Luan Chang Liu Xinghui Wang Yufeng Sun Mengru Zheng Mengya Fang Shuhai Yang Lai Xu Hualin Sun Bin Yu Xiaosong Gu Songlin Zhou | 2023 | Neuroscience Bulletin2023,39,2: | 0 |
| 10 | Achyranthes bidentata polypeptide k attenuates neuroinflammation by inhibiting PI3K/Akt pathway and promoting Nrf2 translocation in BV-2 microglia显示文摘Activated microglia play a critical role in regulating neuroinflammatory responses in central nervous system.Previous studies have shown that Ach yranthes bidentata polypeptide k's(ABPPk s)neuroprotective effects are partly due to its anti-inflammatory effect,but the mechanism remains unknown.Here we investigated the anti-inflam matory effects of ABPPk on LPSactivated BV2 microglia.The results showed that pretreated with ABPPk(0.2-5μg/mL)for 30 minutes reduced the iNOS mediated NO and COX-2 mediated PGE2 production significantly in LPS-activated BV2 microglia.ABPPk(1 and 5μg/mL)also suppressed the production of TNF-α,IL-6,glutamate and ROS significantly. | Cheng Qiong Ge Xiangyu Wang Yitong Zhao Yahong Gong Leilei Ding Fei | 2021 | 解剖学杂志2021,44,S01: | 0 |
| 11 | Effects of I-EGR and Pre-Injection on Performance of Gasoline Compression Ignition(GCI)at Low-Load Condition显示文摘Gasoline compression ignition(GCI)has been considered as a promising combustion concept to yield ultralow NOX and soot emissions while maintaining high thermal efficiency.However,how to improve the low-load performance becomes an urgent issue to be solved.In this paper,a GCI engine model was built to investigate the effects of internal EGR(i-EGR)and pre-injection on in-cylinder temperature,spatial concentration of mixture and OH radical,combustion and emission characteristics,and the control strategy for improving the combustion performance was further explored.The results showed an obvious expansion of the zone with an equivalence ratio between 0.8∼1.2 is realized by higher pre-injection ratios,and the s decreases with the increase of pre-injection ratio,but increases with the increase of i-EGR ratio.The high overlap among the equivalentmixture zone,the hightemperature zone,and the OH radical-rich zone can be achieved by higher i-EGR ratio coupled with higher preinjection ratio.By increasing the pre-injection ratio,the combustion efficiency increases first and then decreases,also achieves the peak value with a pre-injection ratio of 60%and is unaffected by i-EGR.The emissions of CO,HC,NOX,and soot can also be reduced to low levels by the combination of higher i-EGR ratios and a pre-injection ratio of 60%. | Binbin Yang Leilei Liu Yan Zhang Jingyu Gong Fan Zhang Tiezhu Zhang | 2023 | Energy Engineering2023,120,10: | 0 |
| 12 | Integrated Transcriptome and Small RNA Sequencing Analyses Reveals Insights into the Molecular Mechanism of Seed Germination in Mung Bean显示文摘During the life cycle of a plant,seed germination is crucial.Upon ingestion of water,the dry seeds resumed energy metabolism and cellular repair.To dissect the complex mechanisms at the very beginning of seed germination,two approaches including transcriptome and small RNA sequencing were conducted during the water imbibition process of mung bean seeds compared with dry seed.The transcriptome sequencing analysis identified 10,108 differentially expressed genes(DEGs)between dry and imbibed mung bean seeds.KEGG enrichment analyses demonstrated numerous DEGs involved in hormone signaling pathways,carbohydrate,and energy metabolism.Out of the total DEGs,129 genes were investigated to involve in abscisic acid,gibberellin,and ethylene pathways,with 56 genes involved in glycolysis and TCA cycle.Through the analysis of small RNA sequencing among different samples,there were 284 miRNAs found in the imbibed and dried seeds of mung bean containing 213 known and 71 novel miRNAs.From comparison between the two types of seeds,51 miRNAs were differentially expressed.The integrated analyses of transcriptome and miRNAome data showed that 23 DEGs are the putative target genes of 8 miRNAs including miR156,miR171b-3p,miR166e-3p,miR169-1,etc.QRT-PCR was used to validate several DEGs and miRNAs.The data suggested that the seed imbibition process is regulated by a variety of DEGs and microRNAs.Meanwhile,we hope to gain a deeper insight into how mung bean seeds germinate in order to optimize seed growth. | Yanyan Pu Liwen Wang Leilei Li Yujun Si Shubin Xie Yunzhe Cong Dong Wang Yongchao Gong Rumei Tian Xue Chen Xiaoyan Zhang Min Liu Hanfeng Ding Nana Li | 2023 | Phyton-International Journal of Experimental Botany2023,92,6: | 0 |
