| 1 | mTORC2 promotes type I insulin-like growth factor receptor and insulin receptor activation through the tyrosine kinase activity of mTOR显示文摘rapamycin (mTOR ) 的哺乳动物的目标是 raptor-mTOR (mTORC1 ) 和控制多样的细胞的进程的 rictor-mTOR (mTORC2 ) 建筑群的一个核心部件。mTORC1 和 mTORC2 类型下游地调整几个元素我像胰岛素的生长因素受体(IGF 红外) 和胰岛素受体(InsR ) 。然而,它是未知的是否并且 mTOR 怎么自己调整 IGF 红外和 InsR。这里,我们证明 mTOR 拥有意外酷氨酸 kinase 活动并且激活 IGF-IR/InsR。Rapamycin 导致酷氨酸 phosphorylation 和 IGF-IR/InsR 的激活,它大部分依赖于 rictor 和 mTOR。而且, mTORC2 支持 IGF-IR/InsR 的导致 ligand 的激活。导致 IGF 、导致胰岛素的 IGF-IR/InsR phosphorylation 显著地在 rictor 空的房间被损害。胰岛素受体底层(红外) 直接与从而招募的 SIN1 交往 mTORC2 到 IGF-IR/InsR 并且支持 IGF-IR/InsR 的导致 rapamycin 或导致 ligand 的 phosphorylation。mTOR poly 向一般酷氨酸 kinase 底层展出酷氨酸 kinase 活动(Glu-Tyr ) 并且 IGF-IR/InsR。Tyr1131/1136 和 Tyr1146/1151 上的 recombinant mTOR 和 immunoprecipitated mTORC2 phosphorylate IGF 红外和 InsR 分别地。这些效果独立于 IGF-IR/InsR 的内在的 kinase 活动,作为在 kinase 死了的 IGF-IR/InsR 异种上由试金决定了。当从 rictor +/+ MCF-10A 房间的 rictor 和 mTOR immunoprecitates 向 IGF 红外和 InsR 展出酷氨酸 kinase 活动时,从 rictor −/− MCF-10A 房间的 mTOR immunoprecipitates 不导致 IGF 红外和 InsR phosphorylation。在 IGF 红外的残余 Tyr1131 或在 InsR 的 Tyr1146 的 Phosphorylation 缺乏的变化由 mTOR 废除 IGF-IR/InsR 的激活。最后, rictor 的 overexpression 支持导致 IGF 的房间增长。我们的工作作为双特性的 kinase 识别 mTOR 并且澄清 mTORC2 怎么支持 IGF-IR/InsR 激活。 | YancunYin Hui Hua Minjing Li Shu Liu Qingbin Kong Ting Shao Jiao Wang Yuanming Luo Qian Wang Ting Luo Yangfu Jiang | 2016 | Cell Research2016，26，1： | 11 |
| 2 | Signaling pathways and targeted therapy for myocardial infarction显示文摘Although the treatment of myocardial infarction(MI)has improved considerably,it is still a worldwide disease with high morbidity and high mortality.Whilst there is still a long way to go for discovering ideal treatments,therapeutic strategies committed to cardioprotection and cardiac repair following cardiac ischemia are emerging.Evidence of pathological characteristics in MI illustrates cell signaling pathways that participate in the survival,proliferation,apoptosis,autophagy of cardiomyocytes,endothelial cells,fibroblasts,monocytes,and stem cells.These signaling pathways include the key players in inflammation response,e.g.,NLRP3/caspase-1 and TLR4/MyD88/NF-κB;the crucial mediators in oxidative stress and apoptosis,for instance,Notch,Hippo/YAP,RhoA/ROCK,Nrf2/HO-1,and Sonic hedgehog;the controller of myocardial fibrosis such as TGF-β/SMADs and Wnt/β-catenin;and the main regulator of angiogenesis,PI3K/Akt,MAPK,JAK/STAT,Sonic hedgehog,etc.Since signaling pathways play an important role in administering the process of MI,aiming at targeting these aberrant signaling pathways and improving the pathological manifestations in MI is indispensable and promising.Hence,drug therapy,gene therapy,protein therapy,cell therapy,and exosome therapy have been emerging and are known as novel therapies.In this review,we summarize the therapeutic strategies for MI by regulating these associated pathways,which contribute to inhibiting cardiomyocytes death,attenuating inflammation,enhancing angiogenesis,etc.so as to repair and re-functionalize damaged hearts. | Qing Zhang Lu Wang Shiqi Wang Hongxin Cheng Lin Xu Gaiqin Pei Yang Wang Chenying Fu Yangfu Jiang Chengqi He Quan Wei | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 11 |
| 3 | Temperature-dependent optical resonance in a thin-walled tubular oxide microcavity显示文摘This work proposes a temperature-response capability of optical resonance in tubular optical oxide microcavities. The thin wall thickness with a subwavelength scale enables these microcavities to interact with the environment effectively. By optimization of the geometries and materials, the tubular microcavities can be tuned into temperature-inert in vacuum, and the experiments support this design. The experiments prove the idea of utilizing them as temperature-inert microcavities. Contrary wavelength shifts from previous studies were observed, which can be explained with the theoretical model. Furthermore, the theoretical results of the present work suggest that novel rolled-up microtubes could act as an exceptional optical microcavity for the application in temperature response. | Yangfu Fang Xianyun Lin Shiwei Tang Borui Xu Jiao Wang Yongfeng Mei | 2017 | Progress in Natural Science:Materials International2017，27，4： | 1 |
| 6 | Thermal management for the underwater frontend and readout electronics of JUNO 20‑inch PMTs显示文摘Background The Jiangmen underground neutrino observatory(JUNO)is a new generation of long-term operation neutrino experimental platform under construction in Jiangmen,Guangdong province of southern China.The underwater frontend and readout electronics(F&R electronics)are placed nearby the 20-inch PMTs and readout current signals from three PMTs.The electronics are sealed in a stainless-steel underwater box to keep them dry,and temperature control of the electronics plays a significant role in their reliability.Methods A conductive cooling structure based on the passive cooling method is designed for the 20-inch PMT F&R electronics.Both numerical simulation and experimental tests were performed to evaluate the cooling structures'thermal performance.Results The results show that the case temperature of the respective chip for 20-inch PMT F&R electronics is less than 30℃in ambient still water.Conclusion The case temperature of the respective chip meets the strict temperature requirement for the F&R electronics.The JUNO collaboration has adopted this cooling structure for the 20-inch PMT readout electronics. | Yangfu Wang Xiaoshan Jiang Jun Hu Peiliang Wang Lei Fan Shaojing Hou Zhe Ning Yunhua Sun Xiongbo Yan Zheng Wang Ziyue Yan Peiran Ye Jie Zhang Alberto Garfagnini Antonio Bergnoli Riccardo Brugnera Beatrice Jelmini Filippo Marini Marco Grassi Mariia Redchuk Andrea Serafini Katharina von Sturm | 2023 | Radiation Detection Technology and Methods2023，7，3： | 0 |
| 7 | Retrieval-and-alignment based large-scale indoor point cloud semantic segmentation显示文摘Current methods for point cloud semantic segmentation depend on the extraction of descriptive features.However,unlike images,point clouds are irregular and often lack texture information,making it demanding to extract discriminative features.In addition,noise,outliers,and uneven point distribution are commonly present in point clouds,which further complicates the segmentation task.To address these problems,a novel architecture is proposed for direct and accurate large-scale point cloud segmentation based on point cloud retrieval and alignment.The proposed approach involves using a feature-based point cloud retrieval method for searching for reference point clouds with annotations from a dataset.In the following segmentation stage,an overlap-based point cloud registration method has been developed to align the target and reference point clouds.For accurate and robust alignment,an overlap region estimation module is trained to locate the optimal overlap region between two pieces of point clouds in a coarse-to-fine manner.In the detected overlap region,the global and local features of the points are extracted and combined for featuremetric registration to obtain accurate transformation parameters between the target and reference point clouds.After alignment,the annotated segmentation of the reference is transferred to the target point clouds to obtain accurate segmentation results.Extensive experiments are conducted to show that the developed method outperforms the state-of-the-art approaches in terms of both accuracy and robustness against noise and outliers. | Zongyi XU Xiaoshui HUANG Bo YUAN Yangfu WANG Qianni ZHANG Weisheng LI Xinbo GAO | 2024 | Science China(Information Sciences)2024，67，4： | 0 |
