| 1 | Effect of biochar applied with plant growth-promoting rhizobacteria(PGPR)on soil microbial community composition and nitrogen utilization in tomato显示文摘Plant growth-promoting rhizobacteria(PGPR)represent an important microbial community group and have beneficial effects on plant growth and development.A pot experiment was conducted to study the effect of biochar applied with PGPR on the soil microbial community composition and nitrogen use efficiency(NUE)of tomato,which could provide a theoretical basis for rational fertilization.Six treatments were designed:no nitrogen(N),PGPR,or biochar control(CK);biochar without N or PGPR(BCK);N without PGPR or biochar(U);N and PGPR without biochar(UP);N and biochar without PGPR(UB);and N,PGPR,and biochar(UBP).The tomato yield in the UP treatment was 9.09% lower than that in the U treatment,whereas that in the UB treatment was 19.93% higher than that in the U treatment.The tomato yield in the UBP treatment was 32.45%,45.69%,and 10.44% higher than those in the U,UP,and UB treatments,respectively.Biochar combined with PGPR increased the relative abundance of Nitrospira and Bradyrhizobium in the soil.At the tomato maturity stage,the soil NO_(3)^(-)-N content in the UBP treatment was 87.12%,88.12%,and 31.04% higher than those in the U,UP,and UB treatments,respectively.The NUE in the UP treatment was 4.03% lower than that in the U treatment,and that in the UBP treatment was 13.63%,17.66%,and 10.77% higher than those in the U,UP,and UB treatments,respectively.This study showed that biochar combined with PGPR can improve soil microbial community structure and increase the NUE of tomato. | Yuan WANG Wenqing LI Binghai DU Hanhao LI | 2021 | Pedosphere2021，31，6： | 7 |
| 2 | Effects of Soil Texture on the Growth of Young Apple Trees and Soil Microbial Community Structure Under Replanted Conditions显示文摘A two-year field experiment was carried out in order to study the occurrence degree and mechanism of apple replant disease(ARD)in the apple orchards with different soil textures.So we can adopt appropriate controlmeasures according to the severity of ARD.Healthy two-year-old seedlings with consistent growth were selected,of which the root stock was T337 and the scion was Yanfu 3.There were significant differences in biomass between methyl bromide fumigation and replanted treatments,and the difference was the largest in clay loam,followed by sandy loam,and loam,which verified ARD in clay loam was most serious,followed by sandy loam and loam.Based on high-throughput sequencing of fungi in soil samples,fungal richness and diversity were the highest in clay loam,followed by sandy loam,and loam.The relative abundance of Fusarium in SX,SL,FX,FL,WX and WL was 7.33%,19.32%,2.70%,4.24%,10.71%and 23.87%,respectively.Based on Real-time quantitative analysis,there were significant differences in the number of Fusarium oxysporum and Fusarium solani between methyl bromide fumigation and replanted treatments,i.e.,clay loam>sandy loam>loam.Fusarium was the main pathogen causing ARD.This shows that ARD is the most serious under replanted clay loam condition.High-throughput sequencing technology was used to prove the difference in Fusarium was one of the important reasons for ARD under different soil textures.This technology provides a new idea for the prevention and control of ARD. | Yuefan Sheng Haiyan Wang MeiWang Hanhao Li Li Xiang Fengbing Pan Xuesen Chen Xiang Shen Chengmiao Yin Zhiquan Mao | 2020 | Horticultural Plant Journal2020，6，3： | 7 |
| 3 | Noninvasive mechanical auxiliary circulation(NMAC):A general concept and the technological trends显示文摘A series of noninvasive mechanical auxiliary circulation(NMAC)technologies,such as intermittent pneumatic compression(IPC),external counterpulsation(ECP),and anti-G suit,had been widely used to realize noninvasive intervention of human cardiovascular system for different purposes,such as treatments of cardiovascular diseases and protecting pilot from G-induced loss of consciousness(G-LOC)during exposure to sustained accelerations.There are lots of similarities among these NMAC technologies,especially on aspects of hardware constitutions and their physiological effects.However,these technologies were almost independently developed in the past few decades.The similarities and differences were summarized on aspects of hardware constitutions and physiological effects of IPC,ECP and anti-G suit in this paper,and a general concept for NMAC technologies was proposed.This concept did not include a restrict definition,but generally focused on the physiological benefits,while any noninvasive mechanical methods that can achieve such benefits are welcomed.Trends for these typical NMAC technologies,especially about the strategies to realize personalized therapy or to meet new challenges,are discussed.This paper provided a unified perspective for non-invasive mechanical technologies aiming at cardiovascular benefits,and might inspire new technologies to be introduced in. | Wang Yawei Li Jianchao Wang Bitian Liu Hanhao Wu Guifu Fan Yubo | 2022 | Medicine in Novel Technology and Devices2022，，4： | 0 |
| 4 | SUMOylation-triggered ALIX activation modulates extracellular vesicles circTLCD4-RWDD3 to promote lymphatic metastasis of non-small cell lung cancer显示文摘Lymph node(LN)metastasis is one of the predominant metastatic routes of non-small cell lung cancer(NSCLC)and is considered as a leading cause for the unsatisfactory prognosis of patients.Although lymphangiogenesis is well-recognized as a crucial process in mediating LN metastasis,the regulatory mechanism involving lymphangiogenesis and LN metastasis in NSCLC remains unclear.In this study,we employed high-throughput sequencing to identify a novel circular RNA(circRNA),circTLCD4-RWDD3,which was significantly upregulated in extracellular vesicles(EVs)from LN metastatic NSCLC and was positively associated with deteriorated OS and DFS of patients with NSCLC from multicenter clinical cohort.Downregulating the expression of EV-packaged circTLCD4-RWDD3 inhibited lymphangiogenesis and LN metastasis of NSCLC both in vitro and in vivo.Mechanically,circTLCD4-RWDD3 physically interacted with hnRNPA2B1 and mediated the SUMO2 modification at K108 residue of hnRNPA2B1 by upregulating UBC9.Subsequently,circTLCD4-RWDD3-induced SUMOylated hnRNPA2B1 was recognized by the SUMO interaction motif(SIM)of ALIX and activated ALIX to recruit ESCRT-III,thereby facilitating the sorting of circTLCD4-RWDD3 into NSCLC cell-derived EVs.Moreover,EV-packaged circTLCD4-RWDD3 was internalized by lymphatic endothelial cells to activate the transcription of PROX1,resulting in the lymphangiogenesis and LN metastasis of NSCLC.Importantly,blocking EV-mediated transmission of circTLCD4-RWDD3 via mutating SIM in ALIX or K108 residue of hnRNPA2B1 inhibited the lymphangiogenesis and LN metastasis of NSCLC in vivo.Our findings reveal a precise mechanism underlying SUMOylated hnRNPA2B1-induced EV packaging of circTLCD4-RWDD3 in facilitating LN metastasis of NSCLC,suggesting that EV-packaged circTLCD4-RWDD3 could be a potential therapeutic target against LN metastatic NSCLC. | Xiayao Diao Chao Guo Hanhao Zheng Ke Zhao Yuming Luo Mingjie An Yan Lin Jiancheng Chen Yuanlong Li Yuting Li Xuehan Gao Jiaqi Zhang Mengxin Zhou Wenliang Bai Lei Liu Guige Wang Lanjun Zhang Xiaotian He Rusi Zhang Zhihua Li Changhao Chen Shanqing Li | 2023 | Signal Transduction and Targeted Therapy2023，8，12： | 0 |
| 5 | An HGF-dependent positive feedback loop between bladder cancer cells and fibroblasts mediates lymphangiogenesis and lymphatic metastasis显示文摘Background Cancer-associated fibroblasts (CAFs) play a vital role in facilitating tumor progression through extensive reciprocal interplay with cancer cells. Tumor-derived extracellular vesicles (EVs) are the critical mediators involved in the crosstalk between cancer cells and stromal cells, contributing to the metastasis of cancers. Yet, the biological mechanisms of tumor-derived EVs in triggering CAFs phenotype to stimulate the lymph node (LN) metastasis of bladder cancer (BCa) are largely unknown. Here, we aimed to explore the effects and molecular mechanisms of tumor-derived EV-mediated CAFs phenotype in regulating BCa LN metastasis. Methods The high-throughput sequencing was utilized to identify the crucial long non-coding RNA (lncRNA) associated with CAF enrichment in BCa. The functional role of the transition of fibroblasts to CAFs induced by LINC00665-mediated EVs was investigated through the in vitro and in vivo assays. Chromatin isolation by RNA purification assays, fluorescence resonance energy transfer assays, cytokine profiling and patient-derived xenograft (PDX) model were performed to explore the underlying mechanism of LINC00665 in the LN metastasis of BCa. Results We found that CAFs are widely enriched in the tumor microenvironment of BCa, which correlated with BCa lymphangiogenesis and LN metastasis. We then identified a CAF-associated long non-coding RNA, LINC00665, which acted as a crucial mediator of CAF infiltration in BCa. Clinically, LINC00665 was associated with LN metastasis and poor prognosis in patients with BCa. Mechanistically, LINC00665 transcriptionally upregulated RAB27B expression and induced H3K4me3 modification on the promoter of RAB27B through the recruitment of hnRNPL. Moreover, RAB27B-induced EVs secretion endowed fibroblasts with the CAF phenotype, which reciprocally induced LINC00665 overexpression to form a RAB27B-HGF-c-Myc positive feedback loop, enhancing the lymphangiogenesis and LN metastasis of BCa. Importantly, we demonstrated that blocking EV-transmitted LINC00665 or HGF broke this loop and impaired BCa lymphangiogenesis in a PDX model. Conclusion Our study uncovers a precise mechanism that LINC00665 sustains BCa LN metastasis by inducing a RAB27B-HGF-c-Myc positive feedback loop between BCa cells and fibroblasts, suggesting that LINC00665 could be a promising therapeutic target for patients with LN metastatic BCa. | Yuting Li Hanhao Zheng Yuming Luo Yan Lin Mingjie An Yao Kong Yue Zhao Yina Yin Le Ai Jian Huang Changhao Chen | 2023 | Cancer Communications2023，43，12： | 0 |
| 6 | Multi‑compartment Organ‑on‑a‑Chip Based on Electrospun Nanofber Membrane as In Vitro Jaundice Disease Model显示文摘Organ-on-a-chip(OOC)is now becoming a potential alternative to the classical preclinical animal models,which reconstitutes in vitro the basic function of specifc human tissues/organs and dynamically simulates physiological or pathological activities in tissue and organ level.Despite of the much progress achieved so far,there is still an urgent need to explore new biomaterials to construct a reliable and efcient tissue-tissue interface and a general fabrication strategy to expand from single-organ OOC to multi-organ OOC in an easy manner.In this paper,we propose a novel strategy to prepare doublecompartment organ-on-a-chip(DC-OOC)using electrospun poly(l-lactic acid)/collagen I(PLLA/Col I)nanofber membrane as tissue-tissue interface.The unique features of PLLA/Col I nanofber membrane like excellent biocompatibility,strong afnity to multiple cells,adjustable orientation,controllable thickness and porosity endow the tissue-tissue interface with excellent semi-permeability,appropriate mechanical support,inducible cell orientation,good cell adhesion and proliferation.The integration of 3D printing technology during the fabrication process enables precise size control of the tissue-tissue interface and stable bonding with microfuidic channels.More importantly,our fabrication strategy and OOC confguration makes it easy to extend from DC-OOC to multi-compartment organ-on-a-chip(MC-OOC).To show its possible application,in vitro jaundice disease model is established by constructing blood vessel/skin/liver/lung organ-on-a-chip via MC-OOC.The downward trends of the cell viability after perfusion of bilirubin,the variation in cell sensitivity to bilirubin for diferent type of cells and recovery of cell viability after blue light therapy prove the feasibility of this jaundice disease model.We believe this general strategy of constructing tissue-tissue interface and multi-organ OOC can be used for many other in vitro physiological and pathological models. | Fan Lei Minhua Liang Yang Liu Hanhao Huang Haofei Li Hua Dong | 2021 | Advanced Fiber Materials2021，3，6： | 0 |
