| 1 | Biodegradable calcium sulfide-based nanomodulators for H_(2)S-boosted Ca^(2+)-involved synergistic cascade cancer therapy显示文摘Hydrogen sulfide(H_(2)S)is the most recently discovered gasotransmitter molecule that activates multiple intracellular signaling pathways and exerts concentration-dependent antitumor effect by interfering with mitochondrial respiration and inhibiting cellular ATP generation.Inspired by the fact that H_(2)S can also serve as a promoter for intracellular Ca^(2+)influx,tumor-specific nanomodulators(I-CaS@PP)have been constructed by encapsulating calcium sulfide(CaS)and indocyanine green(ICG)into methoxy poly(ethylene glycol)-b-poly(lactide-co-glycolide)(PLGA-PEG).I-CaS@PP can achieve tumor-specific biodegradability with high biocompatibility and pH-responsive H_(2)S release.The released H_(2)S can effectively suppress the catalase(CAT)activity and synergize with released Ca^(2+)to facilitate abnormal Ca^(2+)retention in cells,thus leading to mitochondria destruction and amplification of oxidative stress.Mitochondrial dysfunction further contributes to blocking ATP synthesis and downregulating heat shock proteins(HSPs)expression,which is beneficial to overcome the heat endurance of tumor cells and strengthen ICG-induced photothermal performance.Such a H_(2)S-boosted Ca^(2+)-involved tumor-specific therapy exhibits highly effective tumor inhibition effect with almost complete elimination within 14-day treatment,indicating the great prospect of CaS-based nanomodulators as antitumor therapeutics. | Chuchu Lin Chenyi Huang Zhaoqing Shi Meitong Ou Shengjie Sun Mian Yu Ting Chen Yunfei Yi Xiaoyuan Ji Feng Lv Meiying Wu Lin Mei | 2022 | Acta Pharmaceutica Sinica B2022，12，12： | 0 |
| 2 | Distributed model-free adaptive predictive control of traffic lights for multiple interconnected intersections显示文摘Over the last few decades,urban traffic congestion has been an out-of-control issue globally.Several well-known micromodeling traffic control strategies have been developed for traffic light control.Previous work[1]proposed a distributed feedback controller motivated by back-pressure to maximize the network throughput. | Xinfeng RU Chenyi MEI Weiguo XIA Peng SHI | 2023 | Science China(Information Sciences)2023，66，9： | 0 |
| 3 | Tumor Microenvironment-Specific Chemical Internalization for Enhanced Gene Therapy of Metastatic Breast Cancer显示文摘Benefiting from treating diseases at the genetic level,gene therapy has been considered a new revolution in the biomedical field.However,the extracellular and intracellular barriers during gene transport such as enzymatic degradation and endo-/lysosomal sequestration significantly compromise the therapeutic efficacy.Though photochemical internalization(PCI)has emerged as a promising approach for causing endo-/lysosomal leakage with translocation of the internalized molecules into the cytosol,its effect is still unsatisfactory due to the insufficient light penetration depth.Here,we develop tumor microenvironment-specific enhanced gene delivery by means of ROS generated from the in situ cascaded catalytic reactions in tumors involving GOx-mediated redox reaction and Mn2+-mediated Fenton-like reaction.The efficient enzymatic protection and successful endo-/lysosomal escape of cargo gene complexes have been demonstrated.Moreover,anti-Twist siRNA-loaded G@MMSNs-P exhibit tumor-specific biodegradation,excellent T1-weighted MR imaging,and significant inhibitory effects against breast cancer growth and pulmonary metastasis. | Yun Zhou Mian Yu Changjun Tie Yang Deng Junqing Wang Yunfei Yi Fan Zhang Chenyi Huang Hairong Zheng Lin Mei Meiying Wu | 2021 | Research2021，，1： | 0 |
