1Hepatitis B virus X protein promotes liver cell proliferation via a positive cascade loop involving arachidonic acid metabolism and p-ERK1/2显示文摘肝炎 B 病毒 X 蛋白质(HBx ) 在 hepatocellular 癌的发展起一个关键作用。这里,我们寻求了识别 HBx 由调停的机制肝房间增长。我们发现那 HBx upregulated cyclooxygenase-2 (COX-2 ) 的层次, 5-lipoxygenase (5 哈鱼) 和 phosphorylated 在肝房间的细胞外的调整信号的蛋白质 kinases 1/2 (p-ERK1/2 ) 。导致 HBx 的 p-ERK1/2 被 Gi/o 蛋白质,艇长或哈鱼的抑制废除。另外, HBx 增加了前列腺素 E2 (PGE2 ) 的数量,免除房间线的 leukotriene B4 (LTB4 ) 源于 hepatocytes。而且,这些释放 arachidonic 酸代谢物能激活 ERK1/2。有趣地,激活 ERK1/2 能 upregulate 以一种积极反馈方式的 COX-2 和 5 哈鱼的表示。在结论, HBx 经由包含 COX-2, 5 哈鱼,释放 arachidonic 酸代谢物, Gi/o 蛋白质和 p-ERK1/2 的一个积极反馈环提高并且维持肝房间增长。Changliang Shan Fuqing Xu Shuai Zhang Jiacong YOU Xiaona You Liyan Qiu Jie Zheng Lihong Ye Xiaodong Zhang 2010Cell Research2010,20,5:15
2Fluorescent Organohydrogel with Thermal-Induced Color Change for Anti-counterfeiting显示文摘Smart fluorescent patterns enable dynamic color variation under external stimuli,showing a much higher security level in the field of anti-counterfeiting.However,there is still lacking of a simple and convenient way to achieve dynamic fluorescence changes.Herein,a fluorescent organohydrogel made up of a poly(N,/N-dimethylacrylamide-co-isopropylacrylamide)(p(DMA-NIPAM))hydrogel network and a polyflauryl methacrylate)(PLMA)organogel network was fabricated via a two-step interpenetrating technique.The former network bears naphthalimide moieties(DEAN,green fluorescent monomer)and the later contains 6-acrylamidopicolinic acid(6APA,fluorescent ligand),leading to emitting green fluorescence.When Eu^(3+) was introduced and coordinated with 6APA,the organohydrogel displays red fluorescence,which can further emit yellow after applying thermal stimulus.Furthermore,by adjusting the proportion of comonomers,various organohydrogels can be obtained,which can be programmed and act as an effective platform for the encryption and decryption of secret information.Xiaoxia Le Hui Shang Shirong Gu Guangqiang Yin Fuqing Shan Danyang Li Tao Chen 2022Chinese Journal of Chemistry2022,40,3:3

4Excitation-wavelength-dependent fluorescent organohydrogel for dynamic information anti-counterfeiting显示文摘Anti-counterfeiting labels with various fluorescent colors are of great importance in information encryption-decryption,but are still limited to static information display.Therefore,it is urgent to develop new materials and encryption-decryption logic for improving the security level of secret information.In this study,an organohydrogel made up of poly(N,N-dimethylacrylamide)(pDMA)hydrogel network and polyoctadecyl methacrylate(pSMA)organogel network that copolymerized with two fluorophores,6-acrylamidopicolinic acid moieties(6APA,fluorescent ligand)and spiropyran units(SPMA,photochromic monomer),was prepared by a two-step interpenetrating method.As UV light of 365nm and 254nm can both cleave C_(spiro)-O bonds of SPMA,and the green fluorescence of 6APA-Tb^(3+) can only be excited by 254nm light,the organohydrogel displays yellow and red under the irradiation of 254nm and 365 nm,respectively.In addition to wavelength selectivity,these two fluorophores are thermal-responsive,leading to the fluorescence variation of the organohydrogel during heating process.As a result,secret information loaded on the organohydrogel can be decrypted by the irradiation of UV light,and the authenticity of the information can be further identified by thermal stimulation.Our fluorescent organohydrogel can act as an effective anti-counterfeiting label to improve the information security and protect the information from being cracked.Dong Guo Xiaoxia Le Hui Shang Fuqing Shan Danyang Li Chunfa Ouyang Tao Chen 2023Chinese Chemical Letters2023,34,11:0
