| 1 | Acetylcholinesterase liquid crystal biosensor for identification of AChE inhibitors by a reactivator显示文摘An improved acetylcholinesterase liquid crystal(LC) biosensor has been developed for the identification of organophosphates(OPs) by using a reactivator. When the acetylcholinesterases(AChEs) inhibited by different kinds of OPs are reactived by a reactivator, the catalytic activity of AChEs can be recovered with different activation efficiency because of the different phosphorylation structures formed in the inhibited AChEs. Accordingly, the reactived AChEs can catalyze the hydrolysis of acetylthiocholine to generate thiocholine product in different degrees, which will result in different catalytic growth of AuNPs and further form distinct orientational response of LCs. Based on such a reactivation mechanism, the AChE LC biosensor with a simple, rapid and visual procedure achieves an obvious identification of three OPs pesticides, methamidophos, trichlorfon and paraoxon, by using a pralidoxime reactivator. | DING HuaZhi LIAO ShuZhen XIAO FuBing SHEN GuoLi YU RuQin WU ZhaoYang | 2014 | Science China Chemistry2014，57，11： | 1 |
| 2 | Targeting HECTD3-IKKα axis inhibits inflammation-related metastasis显示文摘Metastasis is the leading cause of cancer-related death.The interactions between circulating tumor cells and endothelial adhesion molecules in distant organs is a key step during extravasation in hematogenous metastasis.Surgery is a common intervention for most primary solid tumors.However,surgical trauma-related systemic inflammation facilitates distant tumor metastasis by increasing the spread and adhesion of tumor cells to vascular endothelial cells(ECs).Currently,there are no effective interventions to prevent distant metastasis.Here,we show that HECTD3 deficiency in ECs significantly reduces tumor metastasis in multiple mouse models.HECTD3 depletion downregulates expression of adhesion molecules,such as VCAM-1,ICAM-1 and E-selectin,in mouse primary ECs and HUVECs stimulated by inflammatory factors and inhibits adhesion of tumor cells to ECs both in vitro and in vivo.We demonstrate that HECTD3 promotes stabilization,nuclear localization and kinase activity of IKKa by ubiquitinating IKKa with K27-and K63-linked polyubiquitin chains at K296,increasing phosphorylation of histone H3 to promote NF-kB target gene transcription.Knockout of HECTD3 in endothelium significantly inhibits tumor cells lung colonization,while conditional knockin promotes that.IKKa kinase inhibitors prevented LPS-induced pulmonary metastasis.These findings reveal the promotional role of the HECTD3-IKKa axis in tumor hematogenous metastasis and providea potential strategy for tumormetastasis prevention. | Fubing Li Huichun Liang Hua You Ji Xiao Houjun Xia Xi Chen Maobo Huang Zhuo Cheng Chuanyu Yang Wenjing Liu Hailin Zhang Li Zeng Yingying Wu Fei Ge Zhen Li Wenhui Zhou Yi Wen Zhongmei Zhou Rong Liu Dewei Jiang Ni Xie Bin Liang Zhenzhen Liu Yanjie Kong Ceshi Chen | 2022 | Signal Transduction and Targeted Therapy2022，7，9： | 1 |
