| 1 | Endothelial Notch activation promotes neutrophil transmigration via downregulating endomucin to aggravate hepatic ischemia/reperfusion injury显示文摘Inflammatory leukocytes infiltration is orchestrated by mechanisms involving chemokines,selectins,addressins and other adhesion molecules derived from endothelial cells(ECs),but how they respond to inflammatory cues and coordinate leukocyte transmigration remain elusive.In this study,using hepatic ischemia/reperfusion injury(HIRI)as a model,we identified that endothelial Notch activation was rapidly and dynamically induced in liver sinusoidal endothelial cells(LSECs)in acute inflammation.In mice with EC-specific Notch activation(NICeCA),HIRI induced exacerbated liver damage.Consistently,endothelial Notch activation enhanced neutrophil infiltration and tumor necrosis factor(TNF)-αexpression in HIRI.Transcriptome analysis and further qRT-PCR as well as immunofluorescence indicated that endomucin(EMCN),a negative regulator of leukocyte adhesion,was downregulated in LSECs from NICeCA mice.EMCN was downregulated during HIRI in wild-type mice and in vitro cultured ECs insulted by hypoxia/re-oxygenation injury.Notch activation in ECs led to increased neutrophil adhesion and transendothelial migration,which was abrogated by EMCN overexpression in vitro.In mice deficient of RBPj,the integrative transcription factor of canonical Notch signaling,although overwhelming sinusoidal malformation aggravated HIRI,the expression of EMCN was upregulated;and pharmaceutical Notch blockade in vitro also upregulated EMCN and inhibited transendothelial migration of neutrophils.The Notch activation-exaggerated HIRI was compromised by blocking LFA-1,which mediated leukocyte adherence by associating with EMCN.Therefore,endothelial Notch signaling controls neutrophil transmigration via EMCN to modulate acute inflammation in HIRI. | Peiran Zhang Kangyi Yue Xinli Liu Xianchun Yan Ziyan Yang Juanli Duan Congcong Xia Xinyuan Xu Mei Zhang Liang Liang Lin Wang Hua Han | 2020 | Science China(Life Sciences)2020，63，3： | 1 |
| 2 | Capacitance Characteristics of Pinus densata,Pinus tabuliformis,Pinus yunnanensis and the hybrids Pinus tabuliformis×Pinus Yunnanensis显示文摘We employed capacitance to evaluate the kinship and interspecific variation of homoploid hybrid conifer Pinus densata,P.tabuliformis,P.yunnanensis and artificial hybrids of P.tabuliformis(maternal parent)and P.yunnanensis(paternal parent)which were cultivated and selected in the common garden experiment.By measuring capacitance spectra under different voltage frequencies,we could differentiate different germplasms based on the electrical response.We aims to demonstrate that P.densata as the hybrid of P.tabuliformis and P.yunnanensis based on the capacitance values of the species,and to provide new evidence to the previously known biological evidence,as well as and the parental effect on the hybrids.Our results revealed that capacitance values between the species are significantly different in the spectra where P.yunnanensis positioned at the lowest and P.densata was much higher than all other species,indicating that P.densata had possessed a great capacity to store electrical energy.The capacitance spectra of P.densata and the artificial hybrid are not similar,which rejected our hypothesis.Both of the capacitance values of P.densata and the hybrids were closer to P.tabuliformis than to P.yunnanensis,which shows that the maternal influence was stronger than the paternal influence.Correlation analysis on the relationship between capacitance and fitnessrelated characteristics showed that capacitance is negatively correlated to mortality rate,and positively correlated with second-year survival rate.High capacitance values of P.densata and some of the hybrids reveal their superior adaptability to harsh environment in the Tibet Plateau.We concluded that capacitance as a new indicator for plant fitness and evolution evidence of homoploid hybrid conifers. | Fengxiang Ma Kangyi Lou Xiaoyang Chen Yue Li | 2020 | Journal of Botanical Research2020，2，3： | 0 |
| 3 | Bovine Placental Bioactive Proteins Preparation and Efficacy Evaluation显示文摘Taking the qualified bovine placenta as the research object,a series of pure physical separation and extraction processes such as tissue fragmentation,ultrasound,freeze-thawed,centrifugation and filtration were used to prepare the bovine placental bioactive proteins.The results of protein concentration showed that bovine placental bioactive proteins prepared in this study could reach(11.33±2.09)mg/mL under optimal experimental condition.The determination of specific components showed that there were abundant exosome like vesicles in the product with particle size ranging from 30 to 150 nm,pie structure under transmission electron microscope and expressing CD9,CD63 and TSG101 by western blot detection.The results of cell efficacy evaluation showed that bovine placental bioactive proteins could significantly promote the proliferation of human skin fibroblasts and had anti-inflammatory effect via down-regulating IL-6 and TNF-αexpressionin RAW264.7 cells. | Li Xuejia Jiang Jiaohua Tang Huijuan Liang Jiafu Zhang Zhaoqing Qi Kangyi Yue Kun Ma yanyan Chen donghuang Chen Haijia Pang keliang | 2023 | China Detergent & Cosmetics2023，8，2： | 0 |
