| 1 | Transcriptomic Analysis of Thermoanaerobacter tengcongensis Grown at Different Temperatures by RNA Sequencing显示文摘Genome sequencing of more than 80 thermophiles has provided powerful databases for the preliminary determination of genes essential to thermal adaptation(Berka et al.,2003;Berezovsky and Shakhnovich,2005;Andrews et al.,2010).A laboratory strain of Thermoanaerobacter tengcongensis MB4 has been shown to grow at temperatures over the | Chuan Wang Chunlei Jin Jihui Zhang Qiyu Bao Bo Liu Huarong Tan | 2015 | Journal of Genetics and Genomics2015,42,6: | 3 |
| 2 | Toll-like receptor 9 defciency induces osteoclastic bone loss via gut microbiota-associated systemic chronic inflammation显示文摘Toll-like receptors(TLRs)play pivotal roles in inflammation and provide important links between the immune and skeletal systems.Although the activation of TLRs may affect osteoclast differentiation and bone metabolism,whether and how TLRs are required for normal bone remodeling remains to be fully explored.In the current study,we show for the first time that TLR9^(-/-)mice exhibit a low bone mass and low-grade systemic chronic inflammation,which is characterized by the expansion of CD4^(+)T cells and increased levels of inflammatory cytokines,including TNFα,RANKL,and IL1β.The increased levels of these cytokines significantly promote osteoclastogenesis and induce bone loss.Importantly,TLR9 deletion alters the gut microbiota,and this dysbiosis is the basis of the systemic inflammation and bone loss observed in TLR9^(-/-)mice.Furthermore,through single-cell RNA sequencing,we identified myeloid-biased hematopoiesis in the bone marrow of TLR9^(-/-)mice and determined that the increase in myelopoiesis,likely caused by the adaptation of hematopoietic stem cells to systemic inflammation,also contributes to inflammation-induced osteoclastogenesis and subsequent bone loss in TLR9^(-/-)mice.Thus,our study provides novel evidence that TLR9 signaling connects the gut microbiota,immune system,and bone and is critical in maintaining the homeostasis of inflammation,hematopoiesis,and bone metabolism under normal conditions. | Peng Ding Qiyuan Tan Zhanying Wei Qiyu Chen Chun Wang Luyue Qi Li Wen Changqing Zhang Chen Yao | 2022 | Bone Research2022,10,3: | 2 |
| 3 | Amelioration of imiquimod-induced psoriasis-like dermatitis in mice by DSW therapy inspired hydrogel显示文摘Psoriasis is a long-lasting and recurrent autoimmune disease which is incurable so far.Dead Sea water(DSW)therapy is an effective approach to help control the symptoms of psoriasis due to the abundant mineral ions in DSW,which inspired the material formulation in this study.Rubidium–Sodium alginate/Polyacrylamide hydrogels(Rb-SA/PAAm gels)composed of sodium alginate and polyacrylamide interpenetrating network structure with different concentrations of rubidium and certain magnesium and zinc content were prepared for the treatment of psoriasis.The obtained results suggest the good mechanical properties of the Rb-SA/PAAm gels including toughness and swelling performance.In terms of in vitro tests,the Rb-SA/PAAm gels not only show nontoxicity to human keratinocyte cell line(Hacats)but also inhibits the activity against inflammatory NF-κβ signaling pathway.Meanwhile,they can release Rb+which enable the Rb-SA/PAAm gels have better antibacterial ability to Streptococcus and Escherichia coli.The results obtained from in vivo tests indicate that these hydrogels could alleviate the symptoms of psoriasis caused by Imiquimod(IMQ)in mice by reducing the inflammatory factor in STAT3 pathway and therefore reduce the immune stimulation of the spleen.In conclusion,the 100Rb-SA/PAAm gel has demonstrated great potential to be a topical wettable dressing for psoriasis treatment. | Xiang He Bing Zhu WeiJia Xie Yu He Jian Song Yi Zhang Chi Sun Hao Li QiYu Tang XinXin Sun Yanni Tan Yong Liu | 2021 | Bioactive Materials2021,6,2: | 2 |
| 4 | Mycorrhizal Networks Interacting with Litter Improves Nutrients and Growth for One Plant through the Vary of N/P Ratio under Karst Soil显示文摘Arbuscular mycorrhizae(AM)fungi affect nutrient uptake for host plants,while it is unclear how AM fungi interacting with soil litter affect plant growth and nutrient utilization through mycorrhizal networks in karst soil of deficient nutrients beyond the rhizosphere.An experiment was conducted in a microcosm composed of a planting compartment for Cinnamomum camphora seedlings with or without Glomus mosseae fungus(M+vs.M−)and an adjacent litter compartment containing or not containing additional litter material of Arthraxon hispidus(L+vs.L−),where the compartments are connected either by nylon mesh of 20μm or 0.45μm which either allow available mycorrhizal networks within the litter compartment or prevent mycelium entering into the litter compartment(N+vs.N−).Plant biomass and nutrients were measured.The results showed that the addition of litter changed the symbiotic process in mycorrhizal colonization,spore,and hyphal density,which when in association with the host plant then affected the biomass,and accumulations of N(nitrogen)and P(phosphorus)in the individual plant as well as root,stem,and leaf respectively.AM fungi increased N and P accumulations and N/P ratio in individual plants and plant tissues.A decrease of the N/P ratio of the individual plant was observed when AM fungus interacted significantly with litter through mycorrhizal networks in the litter compartment.The results indicate that the C.camphora seedlings benefited from litter in nutrient utilization of N and P through the vary of N/P ratio when accessing mycorrhizal networks.These findings suggest that mycorrhizal networks interacting with litter improve growth and nutrients of N and P for plants through the vary of N/P ratio in order to alleviate nutrient limitation under karst soil. | Liling Kang Yuejun He Lipeng Zang Jianpeng Si Ying Yang Kaiping Shen Tingting Xia Qiyu Tan Bangli Wu Yun Guo Wei Wang Qin Liang | 2021 | Phyton-International Journal of Experimental Botany2021,90,3: | 0 |
| 5 | Hippo pathway-manipulating neutrophil-mimic hybrid nanoparticles for cardiac ischemic injury via modulation of local immunity and cardiac regeneration显示文摘The promise of regeneration therapy for restoration of damaged myocardium after cardiac ischemic injury relies on targeted delivery of proliferative molecules into cardiomyocytes whose healing benefits are still limited owing to severe immune microenvironment due to local high concentration of proinflammatory cytokines.Optimal therapeutic strategies are therefore in urgent need to both modulate local immunity and deliver proliferative molecules.Here,we addressed this unmet need by developing neutrophil-mimic nanoparticles NM@miR,fabricated by coating hybrid neutrophil membranes with artificial lipids onto mesoporous silica nanoparticles(MSNs)loaded with microRNA-10b.The hybrid membrane could endow nanoparticles with strong capacity to migrate into infammatory sites and neutralize proinfammatory cytokines and increase the delivery efficiency of microRNA-1Ob into adult mammalian cardiomyocytes(CMs)by fusing with cell membranes and leading to the release of MSNs-miR into cytosol.Upon NM@miR administration,this nanoparticle could home to the injured myocardium,restore the local immunity,and efficiently deliver microRNA-1Ob to cardiomyocytes,which could reduce the activation of Hippo-YAP pathway mediated by excessive cytokines and exert the best proliferative effect of miR-1Ob.This combination therapy could finally improve cardiac function and mitigate ventricular remodeling.Consequently,this work offers a combination strategy of immunity modulation and proliferative molecule delivery to boost cardiac regeneration after injury. | Qiaozi Wang Yanan Song Jinfeng Gao Qiyu Li Jing Chen Yifang Xie Zhengmin Wang Haipeng Tan Hongbo Yang Ning Zhang Juying Qian Zhiqing Pang Zheyong Huang Junbo Ge | 2023 | Acta Pharmaceutica Sinica B2023,13,12: | 0 |
| 6 | AM真菌和枯落物互作下两种喀斯特植物种间竞争较种内竞争更能促进植物养分利用显示文摘枯落物是植物养分获取和土壤养分转化的关键载体。丛枝菌根(Arbuscular mycorrhizae,AM)对植物养分摄取的影响已被广泛认知。然而,在养分亏缺的喀斯特生境中,不同竞争方式的植物如何通过AM真菌和枯落物利用养分尚不清楚。本研究对两种喀斯特适生植物构树(Broussonetia papyrifera)和云贵鹅耳枥(Carpinus pubescens)进行种内竞争和种间竞争种植处理,并通过幼套球囊霉(Glomus etunicatum)接种或不接种处理,以及土壤中添加或不添加两物种叶片混合枯落物处理,测定了植物生物量以及氮、磷、钾浓度等指标,研究植物的生长和养分利用。研究结果表明,AM真菌对两种植物养分摄取影响不同,AM真菌显著提高了种内和种间竞争下构树的养分摄取量,但降低了云贵鹅耳枥的养分摄取量。种间竞争下接种AM真菌,枯落物添加促进了云贵鹅耳枥对氮的摄取,抑制了构树对氮的摄取。接种AM真菌和添加枯落物条件下,种间竞争的构树对氮、磷和钾的摄取量及云贵鹅耳枥对氮的摄取量均高于种内竞争;种间竞争下两物种养分竞争力呈现明显差异,即构树对磷和钾养分竞争力显著提高,对氮则不显著;云贵鹅耳枥仅对钾的养分竞争力显著降低,对氮和磷则无显著影响。这些结果说明,在AM真菌与枯落物相互作用下,两种喀斯特植物种间竞争较种内竞争更能促进植物养分利用。 | Yun Guo Yuejun He Pan Wu Bangli Wu Yan Lin Minhong He Xu Han Tingting Xia Kaiping Shen Liling Kang Qiyu Tan Wenda Ren Yan Sun Qing Li | 2022 | Journal of Plant Ecology2022,15,2: | 0 |
| 7 | Early initiation of ARBs without blood pressure risk via neutrophil membrane-fused pH-sensitive liposomes to reduce cardiomyocyte apoptosis after acute myocardial infarction显示文摘Activation of the local renin-angiotensin system(RAS)promotes cardiomyocyte apoptosis and cardiac remodeling after acute myocardial infarction(AMI).As an anti-RAS drug,the effect of Valsartan in the early stage of acute MI is limited by its low drug concentration in the heart and low dosage.Here,by exploiting the inherent nature of neutrophils migrating to the injured myocardium and the local low-pH microenvironment caused by ischemia and hypoxia after myocardial infarction,we designed nanocarrier(NSLP)-hybridized neutrophil membranes and pH-sensitive liposomes(SLPs)for the delivery of Valsartan(NSLPVal).These functional nanocarriers could mimic neutrophils and are homed to the injured heart;they were also found to respond to a low-pH microenvironment.In the mouse model of MI,we found that NSLP-Val could target the infarct marginal zone and release Valsartan locally in the low-pH microenvironment without affecting hemodynamic stability.Further,locally released angiotensin receptor inhibitors reduced the infarct size and inflammatory response by inhibiting cardiomyocytes.Ultimately,NSLP-Val improved cardiac function and inhibited cardiac hypertrophy and fibrosis. | Jinfeng Gao Wusiman Yakufu Hongbo Yang Yanan Song Qiaozi Wang Qiyu Li Haipeng Tan Jing Chen Dili Sun Zhengmin Wang Jinyan Zhang Xueyi Weng Juying Qian Zhiqing Pang Qibing Wang Zheyong Huang Junbo Ge | 2023 | Nano Research2023,16,7: | 0 |
