2Design and Simulation of Electro-hydrostatic Actuator with a Built-in Power Regulator显示文摘电动静液作动器(EHA)是一种功率电传(PBW)作动器,可将电能输入转换为局部液压能以实现飞行控制。通过取消中央液压源和液压管路,电动静液作动器的可靠性和效率获得提高,但是带宽和刚度受到限制。为解决上述问题,本文提出了一种基于能量调节的新型电动静液作动器。能量调节器由高压蓄能器和比例阀组成,可以根据不同的控制需求储存和管理液压能。提出了转移体积的概念用于评价调节器的工作能力。液压锁用于保持作动器的输出位置。仿真结果表明:经过优化的新结构有效扩展了系统频宽。Kang Rongjie Jiao Zongxia Wang Shaoping Chen Lisha 2009Chinese Journal of Aeronautics2009,22,6:16
3Microstructure characterization and corrosion behavior of Mg-Y-Zn alloys with different long period stacking ordered structures显示文摘Mg-Y-Zn alloys with long period stacking ordered(LPSO)structure have received much attention recently and exhibit great potential in applications such as automotive,aerospace and in bio-medical fields.This paper aimed to investigate the effect of different phase constitution of LPSO structures on corrosion rate of bio-medical Mg-Y-Zn alloys.The results showed that as-cast Mg98.5Y1Zn0.5 alloys containing only 18R structure exhibited the highest corrosion resistance with the corrosion rate of 2.78 mm/year.The precipitation of 14H lamellas within a-Mg grains during solid solution treatment introduced the crystallographic orientation corrosion by accelerating micro-galvanic corrosion.The increase of 18R/14H interfaces deteriorated the corrosion resistance,and the grain boundaries also suffered from severe electrochemical dissolution.This work suggested that Mg-Y-Zn alloys with single LPSO structure(either 18R or 14H)exhibited better corrosion resistance than alloys with co-existence 18R and I4H LPSO structures.Lisha Wang Jinghua Jiang Huan Liu Bassiouny Saleh Aibin Ma 2020Journal of Magnesium and Alloys2020,8,4:11
4Whole-Genome Resequencing of a Worldwide Collection of Rapeseed Accessions Reveals the Genetic Basis of Ecotype Divergence显示文摘Rapeseed (Brassica napus),an important oilseed crop,has adapted to diverse climate zones and latitudes by forming three main ecotype groups,namely winter,semiwinter,and spring types. However,genetic variations underlying the divergence of these ecotypes are largely unknown. Here,we report the global pattern of genetic polymorphisms in rapeseed determined by resequencing a worldwide collection of 991 germplasm accessions.A total of 5.56 and 5.53 million singlenucleotide polymorphisms (SNPs)as Well as 1.86 and 1.92 million InDels were identified by mapping reads to the reference genomes of 'Darmor-bzh'and 'Tapidor,'respectively.We generated a map of allelic drift paths that shows splits and mixtures of the main populations,and revealed an asymmetric evolution of the two subgenomes of B.napus by calculating the genetic diversity and linkage disequilibrium parameters.Selective-sweep analysis revealed genetic changes in genes orthologous to those regulating various aspects of plant development and response to stresses.A genome-wide association study identified SNPs in the promoter regions of FLOWERING LOCUS T and FLOWERING LOCUS C orthologs that corresponded to the different rapeseed ecotype groups. Our study provides important insights into the genomic footprints of rapeseed evolution and flowering-time divergence among three ecotype groups,and will facilitate screening of molecular markers for accelerating rapeseed breeding.Dezhi Wu Zhe Liang Tao Yan Ying Xu Lijie Xuan Juan Tang Gang Zhou Ulrike Lohwasser Shuijin Hua Haoyi Wang Xiaoyang Chen Qian Wang Le Zhu Antony Maodzeka Nazim Hussain Zhilan Li Xuming Li Imran Haider Shamsi Ghulam Jilani Linde Wu Hongkun Zheng Guoping Zhang Boulos Chalhoub Lisha Shen Hao Yu Lixi Jiang 2019Molecular Plant2019,12,1:10
5MSX2 mediates entry of human pluripotent stem cells into mesendoderm by simultaneously suppressing SOX2 and activating NODAL signaling显示文摘发信号的 BMP 怎么集成到并且使动摇人的 pluripotent 干细胞(hPSCs ) 的 pluripotency 电路开始区别进单个细菌层是一个长期的难题。这里,我们报导肌肉片断 homeobox 2 (MSX2 ) , msh 家庭的一个 homeobox 抄写因素, BMP 发信号的直接目标基因和 hPSC 到 mesendoderm 的区别的一个主人调停人。MSX2 的强制表示足够废除 pluripotency 并且导致 hPSCs 的指导 mesendoderm 区别,当 MSX2 弄空损害 mesendoderm 正式就职时。MSX2 是在 hPSCs 的 BMP 小径的直接目标基因,并且能被 Wnt 信号 synergistically 在 mesendoderm 正式就职期间经由 LEF1 激活。而且, MSX2 使动摇通过到 SOX2 倡导者和 SOX2 抄写的压抑的直接绑定的 pluripotency 电路,当 MSX2 通过节的倡导者的直接绑定和激活由 SOX2 的同时的抑制和节的表示的正式就职控制 mesendoderm 系承诺时。有趣地, SOX2 能支持 MSX2 蛋白质的降级,建议在在干细胞命运的控制的二个指定系的因素之间的相互的对抗。一起,我们的调查结果揭示使动摇的关键新机制在 hPSCs 的 pluripotency 和指导系承诺。Qingqing Wu Leisheng Zhang Pei Su Xiaohua Lei Xin Liu Hongtao Wang Lisha Lu Yang Bai Tao Xiong Dong Li Zhengmao Zhu Enkui Duan Erlie Jiang Sizhou Feng Mingzhe Hang Yuanfu Xu Fei Wang Jiaxi Zhou 2015Cell Research2015,25,12:8
6Expression of pathogenesis-related genes in cotton roots in response to Verticillium dahliae PAMP molecules显示文摘VerticiUium wilt disease becomes a major threat to many economically important crops.It is unclear whether and how plant immunity takes place during cotton-Verticillium interaction due to the lack of marker genes.Taking advantage of cotton(Gossypium hirsutum) genome,we discovered pathogenesis-related(PR) gene families,which have been widely used as markers of immune responses in plants.To profile the expression of G.hirsutum PR genes in the process of plant immunity,we treated cotton roots with two immunogenic peptides,flg22 and nlp20 known as pathogen-associated molecular patterns,as well as three VerticiUium dahliae-derived peptides,nlp20^(Vd2),nlp23^(Vd3),and nlp23^(Vd4) which are highly identical to nlp20.Quantitative real-time PCR results revealed that 14 G hirsutum PR gene(GhPR) families were induced or suppressed independently in response to flg22,nlp20,nlp20^(Vd2),nlp23^(Vd3),and nlp23^(Vd4).Most GhPR genes are expressed highest at 3 h post incubation of immunogenic peptides.Compared to flg22 and nlp20,nlp20^(Vd2) is more effective to trigger up-regulated expression of GhPR genes.Notably,both nlp23^(Vd3) and nlp23^(Vd4) are able to induce GhPR gene up-regulation,although they do not induce necrosis on cotton leaves.Thus,our results provide marker genes and new immunogenic peptides for further investigation of cotton-V.dahliae interaction.Xuan Du Sheng Wang Feng Gao Lisha Zhang Jian-Hua Zhao Hui-Shan Guo Chenlei Hua 2017Science China(Life Sciences)2017,60,8:6
7Failure probability estimation of overhead transmission lines considering spatial and temporal variation in severe weather显示文摘Estimation for weather-related failure probability of overhead transmission lines is essential in the reliability assessment of a power system.This paper analyzes the outage and weather data of 110 kV overhead transmission lines in the Guangxi Zhuang Autonomous Region of China during 2011–2014.The result reveals obvious uneven distributions of outage events for time and space due to the spatial and temporal variation of severe weather.Based on the results, an estimation method is proposed in this paper.Split and aggregation is used to smooth the outage and weather data.The poisson model is adopted in our method to investigate the statistic characteristics of transmission line outage events.Regression analysis is applied to obtain the correlation between the weather intensity and history failure rate.Furthermore the method proposed is validated against the empirical outage data.Shuai YANG Wenjun ZHOU Shiyang ZHU Le WANG Lisha YE Xuezhi XIA Han LI 2019Journal of Modern Power Systems and Clean Energy2019,7,1:5
8Neuroprotective effects of total saponins from Rubus parvifolius L. on cerebral ischemia/reperfusion injury in rats显示文摘This study examines the neuroprotective effects and mechanisms of action of total saponins from Rubus parvifolius L. (TSRP) on focal cerebral ischemia and reperfusion injury in rats. Focal cerebral ischemia and reperfusion injury was performed in rats using the suture method. The results indicate that intragastric injection of TSRP, at 5, 10 and 20 mg/kg, could decrease neurological impairment, reduce cerebral infarct volume, diminish pathological changes, and significantly inhibit the apoptosis of neurons surrounding the ischemic area. In addition, TSRP upregulated the expression of the anti-apoptotic factor Bcl-2, at the protein and mRNA levels, and it downregulated the expression of the pro-apoptotic factor Bax, at the protein and mRNA levels. These findings indicate that TSRP protects against cerebral ischemia/reperfusion injury, and that it may do so by regulating the expression of Bcl-2 and Bax.Jisheng Wang Fang Zhang Li Tang Liqiong Sun Xiaolin Song] Lisha Cao Zongyin Qiu Chenglin Zhou 2012Neural Regeneration Research2012,7,3:5
9Macrophage-derived small extracellular vesicles promote biomimetic mineralized collagen-mediated endogenous bone regeneration显示文摘Macrophages play an important role in material-related immune responses and bone formation,but the functionality of macrophage-derived extracellular vesicles(EVs)in material-mediated bone regeneration is still unclear.Here,we evaluated intracellular communication through small extracellular vesicles(sEVs)and its effects on endogenous bone regeneration mediated by biomimetic intrafibrillarly mineralized collagen(IMC).After implantation in the bone defect area,IMC generated more neobone and recruited more mesenchymal stem cells(MSCs)than did extrafibrillarly mineralized collagen(EMC).More CD63+CD90+and CD63+CD163+cells were detected in the defect area in the IMC group than in the EMC group.To determine the functional roles of sEVs,extracellular vesicles from macrophages cultured on different mineralized collagen were isolated,and they showed no morphological differences.However,macrophage-derived sEVs in the IMC group showed an enhanced Young’s modulus and exerted beneficial effects on the osteogenic differentiation of bone marrow MSCs by increasing the expression of the osteoblastic differentiation markers BMP2,BGLAP,COL1,and OSX and calcium nodule formation.Mechanistically,sEVs from IMC-treated macrophages facilitated MSC osteogenesis through the BMP2/Smad5 pathway,and blocking sEV secretion with GW4869 significantly impaired MSC proliferative,immunomodulative and osteogenic potential.Taken together,these findings show that macrophage-derived sEVs may serve as an emerging functional tool in biomaterial-mediated endogenous bone regeneration.Anqi Liu Shanshan Jin Cuicui Fu Shengji Cui Ting Zhang Lisha Zhu Yu Wang Steve G.F.Shen Nan Jiang Yan Liu 2020International Journal of Oral Science2020,12,4:5
10Exosomal HOTAIR promotes proliferation, migration and invasion of lung cancer by sponging miR-203显示文摘Dear Editor,Lung cancer is one of the most common causes of cancerrelated deaths worldwide.Despite great progress in the development of lung cancer treatments,the prognoses of patients with advanced stage cancer remains poor(Torre et al.,2015).Chengcheng Zhang Lisha Xu Guoying Deng Yajie Ding Ke Bi Hansong Jin Jixin Shu Jia Yang Haibin Deng Zhongqi Wang Yin Wang 2020Science China(Life Sciences)2020,63,8:4
11The role of bone marrow-derived cells in the origin of liver cancer revealed by single-cell sequencing显示文摘Objective:Epithelial cancers often originate from progenitor cells,while the origin of hepatocellular carcinoma(HCC)is still controversial.HCC,one of the deadliest cancers,is closely linked with liver injuries and chronic inflammation,which trigger massive infiltration of bone marrow-derived cells(BMDCs)during liver repair.Methods:To address the possible roles of BMDCs in HCC origination,we established a diethylnitrosamine(DEN)-induced HCC model in bone marrow transplanted mice.Immunohistochemistry and frozen tissue immunofluorescence were used to verify DENinduced HCC in the pathology of the disease.The cellular origin of DEN-induced HCC was further studied by single cell sequencing,single-cell nested PCR,and immunofluorescence-fluorescence in situ hybridization.Results:Studies by using single cell sequencing and biochemical analysis revealed that HCC cells in these mice were coming from donor mice BMDCs,and not from recipient mice.Furthermore,the copy numbers of mouse orthologs of several HCC-related genes previously reported in human HCC were also altered in our mouse model.DEN-induced HCCs exhibited a similar histological phenotype and genomic profile as human HCCs.Conclusions:These results suggested that BMDCs are an important origin of HCC,which provide important clues to HCC prevention,detection,and treatments.Lu Chen Xianfu Yi Piao Guo Hua Guo Ziye Chen Chunyu Hou Lisha Qi Yongrong Wang Chengwen Li Peng Liu Yucun Liu Yuanfu Xu Ning Zhang 2020Cancer Biology & Medicine2020,17,1:4
12CPI-17-mediated contraction of vascular smooth muscle is essential for the development of hypertension in obese mice显示文摘Several factors have been implicated in obesity-related hypertension, but the genesis of the hypertension is largely unknown. In this study, we found a significantly upregulated expression of CPI-17(C-kinasepotentiated protein phosphatase 1 inhibitor of 17 kDa) and protein kinase C(PKC) isoforms in the vascular smooth muscles of high-fat diet(HFD)-fed obese mice. The obese wild-type mice showed a significant elevation of blood pressure and enhanced calcium-sensitized contraction of vascular smooth muscles. However, the obese CPI-17-deficient mice showed a normotensive blood pressure, and the calcium-sensitized contraction was consistently reduced. In addition, the mutant muscle displayed an abolished responsive force to a PKC activator and a 30%-50% reduction in both the initial peak force and sustained force in response to various G protein-coupled receptor(GPCR) agonists. Our observations showed that CPI-17-mediated calcium sensitization is mediated through a GPCR/PKC/CPI-17/MLCP/RLC signaling pathway. We therefore propose that the upregulation of CPI-17-mediated calcium-sensitized vasocontraction by obesity contributes to the development of obesity-related hypertension.Jie Sun Tao Tao Wei Zhao Lisha Wei Fan She Pei Wang Yeqiong Li Yanyan Zheng Xin Chen Wei Wang Yanning Qiao Xue-Na Zhang Min-Sheng Zhu 2019Journal of Genetics and Genomics2019,46,3:4
13D2D Multicast Retransmission Algorithm in Mobile Cloud Based on SINR Constraint显示文摘In cellular network, users with same demand and in proximity to each other form the mobile cloud, in which the short-range D2 D technology is employed by users to improve the data dissemination efficiency. In view of the fact that the D2 D links with the poor channel conditions are likely to be the bottleneck of resource utilization improvement, aiming at the differentiation of link quality, this paper proposes a intra-cloud D2 D multicast retransmission algorithm based on SINR constraint to meet the minimum requirement of D2 D retransmission for Qo S. In the proposed algorithm, the model of system link cost is built, the number of multicast retransmission times is restricted and each link quality matrix is traversed to reasonably select the multicast transmitter as well as its routing, which further reduces the link cost consumption, and in turn improves the bandwidth efficiency. Simulation results show that the proposed algorithm is more efficient to improve the bandwidth utilization when the ratio between normal user and non-normal user is small in mobile cloud.Zufan Zhang Lisha Luo Lisha Wang 2016China Communications2016,13,8:4
14The distribution of chlorophyll a in the tropical eastern Indian Ocean in austral summer显示文摘To study the effect of hydrographic factors on the spatial distributions of chlorophyll a (Chl a), an investigation was carried out in the tropical eastern Indian Ocean (80 -100 E along 7 S, and 7 -18 S along 80 E) in December 2010. The fluorescent method was used to obtain total Chl a and size-fractioned Chl a at the 26 stations. The results show that surface Chl a concentration averaged at (0.168 ± 0.095) mg/m 3 s.d. (range: 0.034-0.475 mg/m 3 ), concentrations appeared to be higher in the west for longitudinal variations, and higher in the north for latitudinal variations. Furthermore, the surface Chl a concentration was lower (0.034-0.066 mg/m 3 ) in the region to the south of 16 S. There was a strong subsurface Chl a maximum layer at all stations and the depth of the Chl a maximum increased towards to the east and south along with the respective nitracline. The spatial variation of Chl a was significant: correlation and regression analysis suggests that it was primarily affected by PO 3 4 , N(NO 3 -N+NO 2 -N) and temperature. Size-fractionated Chl a concentration clearly showed that the study area was a typical oligotrophic open ocean, in which picophytoplankton dominated, accounting for approximately 67.8% of total Chl a, followed by nanophytoplankton (24.5%) and microphytoplankton (7.6%). The two larger fractions were sensitive to the limitation of P, while picophytoplankton was primarily affected by temperature.HONG Lisha WANG Chunsheng ZHOU Yadong CHEN Mianrun LIU Hongbin LIN Zhongyang SONG Xunshu 2012Acta Oceanologica Sinica2012,31,5:3
15Pyridinic nitrogen enriched porous carbon derived from bimetal organic frameworks for high capacity zinc ion hybrid capacitors with remarkable rate capability显示文摘Aqueous zinc ion hybrid capacitors(ZIHCs)hold great potential for large-scale energy storage applications owing to their high safety and low cost,but suffer from low capacity and energy density.Herein,pyridinic nitrogen enriched porous carbon(nPC)was successfully synthesized via the growth,subsequent annealing and acid etching of bimetal organic frameworks for high capacity and safe ZIHCs with exceptional rate capability.Benefiting from the mesopores for easy ion diffusion,high electrical conductivity enabled by in-situ grown carbon nanotubes matrix and residual metal Co nanoparticles for fast electron transfer,sufficient micropores and high N content(8.9 at%)with dominated pyridinic N(54%)for enhanced zinc ion storage,the resulting nPC cathodes for ZIHCs achieved high capacities of 302 and137 m Ah g^(-1) at 1 and 18 A g^(-1),outperforming most reported carbon based cathodes.Theoretical results further disclosed that pyridinic N possessed larger binding energy of-4.99 eV to chemically coordinate with Zn2+than other N species.Moreover,quasi-solid-state ZIHCs with gelatin based gel electrolytes exhibited high energy density of 157.6 Wh kg^(-1) at 0.69 kW kg^(-1),high safety and mechanical flexibility to withstand mechanical deformation and drilling.This strategy of developing pyridinic nitrogen enriched porous carbon will pave a new avenue to construct safe ZIHCs with high energy densities.Yao Li Pengfei Lu Ping Shang Lisha Wu Xiao Wang Yanfeng Dong Ronghuan He Zhong-Shuai Wu 2021Journal of Energy Chemistry2021,30,5:3
16Optimization of a Heat Exchanger Using an ARM Core Intelligent Algorithm显示文摘In order to optimize heat transfer in a heat exchanger using an ARM(advanced RISC machine)core intelligent computer algorithm,a new type of controller has been designed.The whole control structure of the heat exchange unit has been conceived on the basis of seven functional modules,including data processing and output,human-computer interaction,alarm,and data communication.The main controller and communication controller have been used in a combined fashion and a new MCU(micro control unit)system scheme has been proposed accordingly.A fuzzy controller has been designed by using a fuzzy control algorithm,and a new mode of heat transfer for the heat exchanger has been implemented by combining the fuzzy controller and the PID(proportioning integral derivative)controller.Finally,the model has been applied to an actual heat exchange station to test and verify the performances of the new approach.Yajuan Jia Juanjuan Wang Lisha Shang 2020Fluid Dynamics & Materials Processing2020,16,5:2
17Improved Electrochemical Performance Based on Nanostructured SnS_2@CoS_2–rGO Composite Anode for Sodium-Ion Batteries显示文摘A promising anode material composed of SnS_2@CoS_2 flower-like spheres assembled from SnS_2 nanosheets and CoS_2 nanoparticles accompanied by reduced graphene oxide(rGO) was fabricated by a facile hydrothermal pathway. The presence of rGO and the combined merits of SnS_2 and CoS_2 endow the SnS_2@-CoS_2–rGO composite with high conductivity pathways and channels for electrons and with excellent properties as an anode material for sodium-ion batteries(SIBs). A high capacity of 514.0 mAh g^(-1) at a current density of200 m A g^(-1) after 100 cycles and a good rate capability can be delivered. The defined structure and good sodium-storage performance of the SnS_2@CoS_2–rGO composite demonstrate its promising application in high-performance SIBs.Xia Wang Xueying Li Qiang Li Hongsen Li Jie Xu Hong Wang Guoxia Zhao Lisha Lu Xiaoyu Lin Hongliang Li Shandong Li 2018Nano-Micro Letters2018,10,3:2
18Improvement in the risk assessment of oral leukoplakia through morphology-related copy number analysis显示文摘Oral leukoplakia is the most common type of oral potentially malignant disorders and considered a precursor lesion to oral squamous cell carcinoma.However,a predictor of oral leukoplakia prognosis has not yet been identified.We investigated whether copy number alteration patterns may effectively predict the prognostic outcomes of oral leukoplakia using routinely processed paraffin sections.Comparison of copy number alteration patterns between oral leukoplakia with hyperplasia(HOL,n=22)and dysplasia(DOL,n=21)showed that oral leukoplakia with dysplasia had a higher copy number alteration rate(86%)than oral leukoplakia with hyperplasia(46%).Oral leukoplakia with dysplasia exhibited a wider range of genomic variations across all chromosomes compared with oral leukoplakia with hyperplasia.We also examined a retrospective cohort of 477 patients with oral leukoplakia with hyperplasia with detailed follow-up information.The malignant transformation(MT,n=19)and leukoplakia recurrence(LR,n=253)groups had higher frequencies of aneuploidy events and copy number loss rate than the free of disease(FD,n=205)group.Together,our results revealed the association between the degree of copy number alterations and the histological grade of oral leukoplakia and demonstrated that copy number alteration may be effective for prognosis prediction in oral leukoplakia patients with hyperplasia.Xiaotian Li Lu Liu Jianyun Zhang Ming Ma Lisha Sun Xuefen Li Heyu Zhang Jianbin Wang Yanyi Huang Tiejun Li 2021Science China(Life Sciences)2021,64,9:2
19Generation of rat blood vasculature and hematopoietic cells in rat-mouse chimeras by blastocyst complementation显示文摘Interspecies chimera through blastocyst complementation could be an alternative approach to create human organs in animals by using human pluripotent stem cells.A mismatch of the major histocompatibility complex of vascular endothelial cells between the human and host animal will cause graft rejection in the transplanted organs.Therefore,to achieve a transplantable organ in animals without rejection,creation of vascular endothelial cells derived from humans within the organ is necessary.In this study,to explore whether donor xeno-pluripotent stem cells can compensate for blood vasculature in host animals,we generated rat-mouse chimeras by injection of rat embryonic stem cells(rESCs)into mouse blastocysts with deficiency of Flk-1 protein,which is associated with endothelial and hematopoietic cell development.We found that rESCs could differentiate into vascular endothelial and hematopoietic cells in the rat-mouse chimeras.The whole yolk sac(YS)of Flk-1^EGFP/ECFP rat-mouse chimera was full of rat blood vasculature.Rat genes related to vascular endothelial cells,arteries,and veins,blood vessels formation process,as well as hematopoietic cells,were highly expressed in the YS.Our results suggested that rat vascular endothelial cells could undergo proliferation,migration,and self-assembly to form blood vasculature and that hematopoietic cells could differentiate into B cells,T cells,and myeloid cells in rat-mouse chimeras,which was able to rescue early embryonic lethality caused by Flk-1 deficiency in mouse.Xiaomin Wang Hui Shi Juanjuan Zhou Qingjian Zou Quanjun Zhang Shixue Gou Pengfei Chen Lisha Mou Nana Fan Yangyang Suo Zhen Ouyang Chengdan Lai Quanmei Yan Liangxue Lai 2020Journal of Genetics and Genomics2020,47,5:2
20Overexpressing dominant-negative FGFR2-IIIb impedes lung branching morphogenesis in pigs显示文摘Genetic studies with mouse models have shown that fibroblast growth factor receptor 2-IIIb(FGFR2-IIIb)plays crucial roles in lung development and differentiation. To evaluate the effect of FGFR2-IIIb in pig lung development, we employed somatic cell nuclear transfer(SCNT) technology to generate transgenic pig fetuses overexpressing the transmembrane(dn FGFR2-IIIb-Tm) and soluble(dn FGFR2-IIIb-HFc) forms of the dominant-negative human FGFR2-IIIb driven by the human surfactant protein C(SP-C) promoter,which was specifically expressed in lung epithelia. Eight dn FGFR2-IIIb-Tm transgenic and twelve dn FGFR2-IIIb-HFc transgenic pig fetuses were collected from three and two recipient sows, respectively.Repression of FGFR2-IIIb in lung epithelia resulted in smaller lobes and retardation of alveolarization in both forms of dn FGFR2-IIIb transgenic fetuses. Moreover, the dn FGFR2-IIIb-HFc transgenic ones showed more deterioration in lung development. Our results demonstrate that disruption of FGFR2-IIIb signaling in the epithelium impedes normal branching and alveolarization in pig lungs, which is less severe than the results observed in transgenic mice. The dn FGFR2-IIIb transgenic pig is a good model for the studies of blastocyst complementation as well as the mechanisms of lung development and organogenesis.Qin Chen Bin Fang Ying Wang Chu Li Xiaoxue Li Ronggen Wang Qiang Xiong Lining Zhang Yong Jin Manling Zhang Xiaorui Liu Lin Li Lisha Mou Rongfeng Li Haiyuan Yang Yifan Dai 2018Journal of Genetics and Genomics2018,45,3:2
