| 1 | TGIF2 promotes the progression of lung adenocarcinoma by bridging EGFR/RAS/ERK signaling to cancer cell stemness显示文摘TGF-β-induced factor homeobox 2(TGIF2)is a transcription regulator that plays essential roles in the regulation of development and cell fate decisions.Aberrant expression of TGIF family proteins has been observed in several cancers,including ovarian,esophageal,and colorectal cancers.Here,we report that TGIF2 mediates the EGFR–RAS–ERK signaling pathway to enhance the stemness of lung adenocarcinoma(LUAD)cells and,therefore,promote the progression and metastasis of LUAD.We found that high TGIF2 expression was closely correlated with tumor growth,lymph node metastasis,and survival of patients with LUAD.Mice bearing TGIF2-silenced H1299 xenografts developed smaller tumors and fewer lung metastases.Importantly,silencing TGIF2 decreased the cancer stem cell(CSC)-like properties in A549 and H1299 cells.Furthermore,we identified that TGIF2 binding to the OCT4 promoter promotes its expression.In both LUAD cells and in vivo LUAD mouse models,we revealed that EGFR–RAS–ERK signaling phosphorylated TGIF2 and increased its stability,which was important for TGIF2-promoted LUAD stemness since phosphorylation-deficient TGIF2 mutants lost these functions.Thus,our study revealed that an important factor,TGIF2,bridges EGFR signaling to the CSC characteristics of LUAD cells,which can be utilized as an effective target for LUAD therapy. | Renle Du Wenzhi Shen Yi Liu Wenjuan Gao Wei Zhou Jun Li Shuangtao Zhao Chong Chen Yanan Chen Yanhua Liu Peiqing Sun Rong Xiang Yi Shi Yunping Luo | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 7 |

| 3 | Separation and enrichment of trace ractopamine in biological samples by uniformly-sized molecularly imprinted polymers显示文摘In order to prepare a high capacity packing material for solid-phase extraction with specific recognition ability of trace ractopamine in biological samples, uniformly-sized, molecularly imprinted polymers (MIPs) were prepared by a multi-step swelling and polymerization method using methacrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker, and toluene as a porogen respectively. Scanning electron microscope and specific surface area were employed to identify the characteristics of MIPs. Ultraviolet spectroscopy, Fourier transform infrared spectroscopy, Scatchard analysis and kinetic study were performed to interpret the specific recognition ability and the binding process of MIPs. The results showed that, compared with other reports, MIPs synthetized in this study showed high adsorption capacity besides specific recognition ability. The adsorption capacity of MIPs was 0.063 mmol/g at 1 mmol/L ractopamine concentration with the distribution coefficient 1.70. The resulting MIPs could be used as solid-phase extraction materials for separation and enrichment of trace ractopamine in biological samples. | Ya Li Qiang Fu Meng Liu Yuan-Yuan Jiao Wei Du Chong Yu Jing Liu Chun Chang Jian Lu | 2012 | Journal of Pharmaceutical Analysis2012，2，6： | 4 |
| 4 | Electrical properties and luminescence properties of 0.96(K0.48Na0.52)(Nb0.95Sb0.05)–0.04Bi0.5(Na0.82K0.18)0.5ZrO3–xSm lead-free ceramics显示文摘In this paper,Sm-doped 0.96(K0.48 Na0.52)(Nb0.95 Sb0.05)–0.04 Bi0.5(Na0.82 K0.18)0.5 Zr O3(abbreviated as KNSN–0.04 BNKZ)lead-free piezoelectric ceramics were prepared by conventional solid-state sintering method and the effects of Sm2 O3 on the phase structure,microstructure,electrical and luminescent properties of KNSN–0.04 BNKZ potteries were studied.Results revealed that a single solid solution phase with pseudo-cubic perovskite structure was formed between KNSN–0.04 BNKZ and Sm2 O3.Existence of weak dielectric/ferroelectric properties with a diffuse dielectric anomaly and slim P–E hysteresis loops of the Sm-doped KNSN–0.04 BNKZ demonstrated the ferroelectric relaxor behavior of the KNNS–0.04 BNKZ–x Sm ceramics.Accordingly,the temperature stability and fatigue behavior of the modified ceramics were significantly improved.It was found that the KNSN–0.04 BNKZ ceramics with 0.002 mol Sm addition exhibited nearly temperature independent properties and fatigue-free behavior.Moreover,Sm-modified KNSN–0.04 BNKZ exhibits a bright photoluminescence with a strong orange emission under visible light irradiation.As a material with both electrical and luminescent properties,it has good application prospect in future optoelectronic components by integrating its luminescent and electrical properties. | Wei LI Jigong HAO Wei LI Juan DU Peng FU Wenzhi SUN Chong CHEN Zhijun XU Ruiqing CHU | 2020 | Journal of Advanced Ceramics2020，9，1： | 2 |
| 5 | Research progress on myocardial regeneration: what is new?显示文摘The regeneration capacity of cardiomyocytes(CMs)is retained in neonatal mouse hearts but is limited in adult mouse Myocardial infarction(MI)in adult hearts usually leads to the loss of large amounts of cardiac tissue,and then accelerates the process of cardiac remodeling and heart failure.Therefore,it is necessary to explore the potential mechanisms of CM regeneration in the neonates and develop potential therapies aimed at promoting CM regeneration and cardiac repair in adults.Currently,studies indicate that a number of mechanisms are involved in neonatal endogenous myocardial regeneration,including cell cycle regulators,transcription factors,non-coding RNA,signaling pathways,acute inflammation,hypoxia,protein kinases,and others.Understanding the mechanisms of regeneration in neonatal CMs after MI provides theoretical support for the studies related to the promotion of heart repair after MI in adult mammals.However,several difficulties in the study of CM regeneration still need to be overcome.This article reviews the potential mechanisms of endogenous CM regeneration in neonatal mouse hearts and discusses possible therapeutic targets and future research directions. | Chong Du Yi Fan Ya-Fei Li Tian-Wen Wei Lian-Sheng Wang | 2020 | Chinese Medical Journal2020，，6： | 2 |

| 7 | Development of low-coherence high-power laser drivers for inertial confinement fusion显示文摘The use of low-coherence light is expected to be one of the effective ways to suppress or even eliminate the laser–plasma instabilities that arise in attempts to achieve inertial confinement fusion.In this paper,a review of low-coherence high-power laser drivers and related key techniques is first presented.Work at typical low-coherence laser facilities,including Gekko XII,PHEBUS,Pharos III,and Kanal-2 is described.The many key techniques that are used in the research and development of low-coherence laser drivers are described and analyzed,including low-coherence source generation,amplification,harmonic conversion,and beam smoothing of low-coherence light.Then,recent progress achieved by our group in research on a broadband low-coherence laser driver is presented.During the development of our low-coherence high-power laser facility,we have proposed and implemented many key techniques for working with low-coherence light,including source generation,efficient amplification and propagation,harmonic conversion,beam smoothing,and precise beam control.Based on a series of technological breakthroughs,a kilojoule low-coherence laser driver named Kunwu with a coherence time of only 300 fs has been built,and the first round of physical experiments has been completed.This high-power laser facility provides not only a demonstration and verification platform for key techniques and system integration of a low-coherence laser driver,but also a new type of experimental platform for research into,for example,high-energy-density physics and,in particular,laser–plasma interactions. | Yanqi Gao Yong Cui Lailin Ji Daxing Rao Xiaohui Zhao Fujian Li Dong Liu Wei Feng Lan Xia Jiani Liu Haitao Shi Pengyuan Du Jia Liu Xiaoli Li Tao Wang Tianxiong Zhang Chong Shan Yilin Hua Weixin Ma Xun Sun Xianfeng Chen Xiuguang Huang Jian Zhu Wenbing Pei Zhan Sui Sizu Fu | 2020 | Matter and Radiation at Extremes2020，5，6： | 1 |

| 11 | Improved methodology for efficient establishment of the myocardial ischemia-reperfusion model in pigs through the median thoracic incision显示文摘To investigate the feasibility and effectiveness of establishing porcine ischemia-reperfusion models by ligating the left anterior descending(LAD)coronary artery,we first randomly divided 16 male Bama pigs into a sham group and a model group.After anesthesia,we separated the arteries and veins.Subsequently,we rapidly located the LAD coronary artery at the beginning of its first diagonal branch through a mid-chest incision.Then,we loosened and released the ligation line after five minutes of pre-occlusion.Finally,we ligated the LAD coronary artery in situ two minutes later and loosened the ligature 60 min after ischemia.Compared with the sham group,electrocardiogram showed multiple continuous lead ST-segment elevations,and ultrasound cardiogram showed significantly lower ejection fraction and left ventricular fractional shortening at one hour and seven days post-operation in the model group.Twenty-four hours after the operation,cardiac troponin T and creatine kinase-MB isoenzyme levels significantly increased in the model group,compared with the sham group.Hematoxylin and eosin staining showed the presence of many inflammatory cells infiltrating the interstitium of the myocardium in the model group but not in the sham group.Masson staining revealed a significant increase in infarct size in the ischemia/reperfusion group.All eight pigs in the model group recovered with normal sinus heart rates,and the survival rate was 100%.In conclusion,the method can provide an accurate and stable large animal model for preclinical research on ischemia/reperfusion with a high success rate and homogeneity of the myocardial infarction area. | Liuhua Zhou Jiateng Sun Tongtong Yang Sibo Wang Tiankai Shan Lingfeng Gu Jiawen Chen Tianwen Wei Di Zhao Chong Du Yulin Bao Hao Wang Xiaohu Lu Haoliang Sun Meng Lv Di Yang Liansheng Wang | 2023 | The Journal of Biomedical Research2023，37，4： | 1 |
| 12 | Protein kinases in cardiovascular diseases显示文摘Cardiovascular disease(CVD)remains the leading cause of death worldwide.Therefore,exploring the mechanism of CVDs and critical regulatory factors is of great significance for promoting heart repair,reversing cardiac remodeling,and reducing adverse cardiovascular events.Recently,significant progress has been made in understanding the function of protein kinases and their interactions with other regulatory proteins in myocardial biology.Protein kinases are positioned as critical regulators at the intersection of multiple signals and coordinate nearly every aspect of myocardial responses,regulating contractility,metabolism,transcription,and cellular death.Equally,reconstructing the disrupted protein kinases regulatory network will help reverse pathological progress and stimulate cardiac repair.This review summarizes recent researches concerning the function of protein kinases in CVDs,discusses their promising clinical applications,and explores potential targets for future treatments. | Jiawen Chen Yafei Li Chong Du Tianwen Wei Tiankai Shan Liansheng Wang | 2022 | Chinese Medical Journal2022，，5： | 0 |
| 13 | Antagonizing the irreversible thrombomodulin-initiated proteolytic signaling alleviates age-related liver fibrosis via senescent cell killing显示文摘Cellular senescence is a stress-induced,stable cell cycle arrest phenotype which generates a pro-inflammatory microenvironment,leading to chronic inflammation and age-associated diseases.Determining the fundamental molecular pathways driving senescence instead of apoptosis could enable the identification of senolytic agents to restore tissue homeostasis.Here,we identify thrombomodulin(THBD)signaling as a key molecular determinant of the senescent cell fate.Although normally restricted to endothelial cells,THBD is rapidly upregulated and maintained throughout all phases of the senescence program in aged mammalian tissues and in senescent cell models.Mechanistically,THBD activates a proteolytic feed-forward signaling pathway by stabilizing a multi-protein complex in early endosomes,thus forming a molecular basis for the irreversibility of the senescence program and ensuring senescent cell viability.Therapeutically,THBD signaling depletion or inhibition using vorapaxar,an FDA-approved drug,effectively ablates senescent cells and restores tissue homeostasis in liver fibrosis models.Collectively,these results uncover proteolytic THBD signaling as a conserved pro-survival pathway essential for senescent cell viability,thus providing a pharmacologically exploitable senolytic target for senescence-associated diseases. | Christopher C.Pan Raquel Maeso-Díaz Tylor R.Lewis Kun Xiang Lianmei Tan Yaosi Liang Liuyang Wang Fengrui Yang Tao Yin Calvin Wang Kuo Du De Huang Seh Hoon Oh Ergang Wang Bryan Jian Wei Lim Mengyang Chong Peter B.Alexander Xuebiao Yao Vadim Y.Arshavsky Qi-Jing Li Anna Mae Diehl Xiao-Fan Wang | 2023 | Cell Research2023，33，7： | 0 |
