| 2 | Small-Molecule Fluorophores for Near-Infrared IIb Imaging and ImageGuided Therapy of Vascular Diseases显示文摘Accurate and dynamic visualization of vascular diseases can contribute to restraining further deterioration from diseases in a timely manner.However,visualization is still unable to precisely determine whether and to what extent blood vessels or brain tissues are damaged.Here,we report novel benzobis(1,2,5-thiadiazole)-based second near-infrared region(NIR-II)fluorophores HY1-HY4 with highly twisted structures(55°at the S_(0) state),extremely strong aggregation-induced emission(AIE)characteristics(I/I_(0)>13),and remarkably high fluorescence quantum yields(QYs)(up to 14.45%)in the NIR-II region(>1000 nm)and∼0.27%in the nearinfrared IIb window(NIR-IIb,>1500 nm)in aqueous solution.Using NIR-IIb AIE HY4 dots,high-resolution NIR-IIb fluorescence imaging of revascularization and thrombolysis,and real-time feedback of the therapeutic efficacy of Chinese medicine Dengzhan Xixin injection(DXI)on ischemic stroke,were achieved for the first time.In addition,results showed that DXI conferred neuroprotection against cerebral ischemia injury mediated via the angiogenesis pathway.These attractive results provide a new perspective for designing ultrabright NIR-IIb probes for vascular-related phenomena,disease assessment,and precise intraoperative imageguided therapy with a deeper tissue penetration depth and higher resolution. | Yang Li Hua Zhu Xiaobo Wang Yan Cui Lijuan Gu Xiaowen Hou Mengting Guan Junzhu Wu Yuling Xiao Xiaoxing Xiong Xianli Meng Xuechuan Hong | 2022 | CCS Chemistry2022,4,12: | 0 |
| 3 | Engineering Multipedal DNA Walker on Paper for Sensitive Electrochemical Detection of Plant MicroRNA显示文摘MicroRNAs (miRNAs) are vital regulators in both plants and animals. Therefore, it is highly desirable to develop portable and user-friendly biosensors for convenient and sensitive detection of miRNAs. Herein, a novel paper-based electrochemical biosensor was intelligently engineered for the detection of plant miRNA based on a smart DNA walking machine and λ-exonuclease (λ-Exo)-assisted target recycling amplification. Using TaMIR5086 as a target plant miRNA, the presence of TaMIR5086 could initiate the target recycling process and activate the DNA walker to move along the track on the paper. Then, numerous electroactive molecules-labeled single-strand DNA (ssDNA) would be released and adsorbed onto the surface of screen-printed electrode, generating a remarkably increased electrochemical signal. Benefitting from the dual amplification, the developed biosensor exhibits excellent analytical performance toward TaMIR5086 with a detection limit down to 0.37 pmol/L. Furthermore, the paper-based biosensor could be applied for the analysis of target miRNA in complex biological samples, which found great potential in the fields of miRNA analysis and plant biology research. | Xiaojuan Liu Junzhu Xiang Hao Cheng Yuying Wang Feng Li | 2022 | Chinese Journal of Chemistry2022,40,23: | 0 |
| 4 | NDRG1 promotes endothelial dysfunction and hypoxia-induced pulmonary hypertension by targeting TAF15显示文摘Background:Pulmonary hypertension(PH)represents a threatening pathophysiologic state that can be induced by chronic hypoxia and is characterized by extensive vascular remodeling.However,the mechanism underlying hypoxia-induced vascular remodeling is not fully elucidated.Methods and Results:By using quantitative polymerase chain reactions,western blotting,and immunohistochemistry,we demon-strate that the expression of N-myc downstream regulated gene-1(NDRG1)is markedly increased in hypoxia-stimulated endothelial cells in a time-dependent manner as well as in human and rat endothelium lesions.To determine the role of NDRG1 in endothelial dysfunction,we performed loss-of-function studies using NDRG1 short hairpin RNAs and NDRG1 over-expression plasmids.In vitro,silencing NDRG1 attenuated proliferation,migration,and tube formation of human pulmonary artery endothelial cells(HPAECs)un-der hypoxia,while NDRG1 over-expression promoted these behaviors of HPAECs.Mechanistically,NDRG1 can directly interact with TATA-box binding protein associated factor 15(TAF15)and promote its nuclear localization.Knockdown of TAF15 abrogated the effect of NDRG1 on the proliferation,migration and tube formation capacity of HPAECs.Bioinformatics studies found that TAF15 was involved in regulating PI3K-Akt,p53,and hypoxia-inducible factor 1(HIF-1)signaling pathways,which have been proved to be PH-related pathways.In addition,vascular remodeling and right ventricular hypertrophy induced by hypoxia were markedly alleviated in NDRG1 knock-down rats compared with their wild-type littermates.Conclusions:Taken together,our results indicate that hypoxia-induced upregulation of NDRG1 contributes to endothelial dysfunction through targeting TAF15,which ultimately contributes to the development of hypoxia-induced PH. | Chengwei Li Junzhu Lv Gulinuer Wumaier Yu Zhao Liang Dong Yuzhen Zeng Ning Zhu Xiujuan Zhang Jing Wang Jingwen Xia Shengqing Li | 2023 | Precision Clinical Medicine2023,6,4: | 0 |
