| 1 | Inhibition of gasdermin D-dependent pyroptosis attenuates the progression of silica-induced pulmonary inflammation and fibrosis显示文摘Silicosis is a leading cause of occupational disease-related morbidity and mortality worldwide,but the molecular basis underlying its development remains unclear.An accumulating body of evidence supports gasdermin D(GSDMD)-mediated pyroptosis as a key component in the development of various pulmonary diseases.However,there is little experimental evidence connecting silicosis and GSDMD-driven pyroptosis.In this work,we investigated the role of GSDMD-mediated pyroptosis in silicosis.Single-cell RNA sequencing of healthy and silicosis human and murine lung tissues indicated that GSDMD-induced pyroptosis in macrophages was relevant to silicosis progression.Through microscopy we then observed morphological alterations of pyroptosis in macrophages treated with silica.Measurement of interleukin-1βrelease,lactic dehydrogenase activity,and real-time propidium iodide staining further revealed that silica induced pyroptosis of macrophages.Additionally,we verified that both canonical(caspase-1-mediated)and non-canonical(caspase-4/5/11-mediated)signaling pathways mediated silica-induced pyroptosis activation,in vivo and in vitro.Notably,Gsdmd knockout mice exhibited dramatically alleviated silicosis phenotypes,which highlighted the pivotal role of pyroptosis in this disease.Taken together,our results demonstrated that macrophages underwent GSDMD-dependent pyroptosis in silicosis and inhibition of this process could serve as a viable clinical strategy for mitigating silicosis. | Meiyue Song Jiaxin Wang Youliang Sun Junling Pang Xiaona Li Yuan Liu Yitian Zhou Peiran Yang Tianhui Fan Ying Liu Zhaoguo Li Xianmei Qi Baicun Li Xinri Zhang Jing Wang Chen Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，3： | 5 |
| 2 | Gefitinib and fostamatinib target EGFR and SYK to attenuate silicosis:a multi-omics study with drug exploration显示文摘Silicosis is the most prevalent and fatal occupational disease with no effective therapeutics,and currently used drugs cannot reverse the disease progress.Worse still,there are still challenges to be addressed to fully decipher the intricated pathogenesis.Thus,specifying the essential mechanisms and targets in silicosis progression then exploring anti-silicosis pharmacuticals are desperately needed.In this work,multi-omics atlas was constructed to depict the pivotal abnormalities of silicosis and develop targeted agents.By utilizing an unbiased and time-resolved analysis of the transcriptome,proteome and phosphoproteome of a silicosis mouse model,we have verified the significant differences in transcript,protein,kinase activity and signaling pathway level during silicosis progression,in which the importance of essential biological processes such as macrophage activation,chemotaxis,immune cell recruitment and chronic inflammation were emphasized.Notably,the phosphorylation of EGFR(p-EGFR)and SYK(pSYK)were identified as potential therapeutic targets in the progression of silicosis.To inhibit and validate these targets,we tested fostamatinib(targeting SYK)and Gefitinib(targeting EGFR),and both drugs effectively ameliorated pulmonary dysfunction and inhibited the progression of inflammation and fibrosis.Overall,our drug discovery with multi-omics approach provides novel and viable therapeutic strategies for the treatment of silicosis. | Mingyao Wang Zhe Zhang Jiangfeng Liu Meiyue Song Tiantian Zhang Yiling Chen Huiyuan Hu Peiran Yang Bolun Li Xiaomin Song Junling Pang Yanjiang Xing Zhujie Cao Wenjun Guo Hao Yang Jing Wang Juntao Yang Chen Wang | 2022 | Signal Transduction and Targeted Therapy2022，7，6： | 1 |

| 4 | Single-cell transcriptional profile of ACE2 in healthy and failing human hearts显示文摘Dear Editor,The coronavirus disease 2019(COVID-19)pandemic,which is caused by SARS-Co V-2,has gained serious attention from medical practitioners around the world in the past few months.Approximately 20%of critically ill COVID-19 patients were reported to have suffered myocardial injury.The specific mechanism of this pathology requires further investigation(Yang et al.,2020). | Yitian Zhou Yongfa Huang Xiaomin Song Xiaoxiao Guo Junling Pang Jing Wang Shuyang Zhang Chen Wang | 2021 | Science China(Life Sciences)2021，64，4： | 0 |
| 5 | Improved Weighted Local Contrast Method for Infrared Small Target Detection显示文摘In order to address the problem of high false alarm rate and low probabilities of infrared small target detection in complex low-altitude background,an infrared small target detection method based on improved weighted local contrast is proposed in this paper.First,the ratio information between the target and local background is utilized as an enhancement factor.The local contrast is calculated by incorporating the heterogeneity between the target and local background.Then,a local product weighted method is designed based on the spatial dissimilarity between target and background to further enhance target while suppressing background.Finally,the location of target is obtained by adaptive threshold segmentation.As experimental results demonstrate,the method shows superior performance in several evaluation metrics compared with six existing algorithms on different datasets containing targets such as unmanned aerial vehicles(UAV). | Pengge Ma Jiangnan Wang Dongdong Pang Tao Shan Junling Sun Qiuchun Jin | 2024 | Journal of Beijing Institute of Technology2024，33，1： | 0 |
| 6 | Molecular Cloning and Bioinformatics Analysis of araC Gene of Vibrio alginolyticus显示文摘[Objective]To clone araC gene of Vibrio alginolyticus HY9901 strain,and analyze bioinformatics.[Methods]the whole genome sequence of Vibrio alginolyticus on GenBank was used to design specific primers.According to the principle of PCR amplification sequence,the target gene araC was amplified,and then the sequence was further analyzed by bioinformatics method to establish the phylogenetic tree of araC gene and its corresponding subunit three-dimensional structure model.[Results]Sequence analysis revealed araC gene is 711 bp and encodes a putative protein of 236 amino acids.The predicted molecular mass of AraC was 26.92 ku.Using Signal P 4.0 and TMHMM Server 2.0 software for analysis,it was predicted that the AraC protein did not contain a signal peptide or a transmembranous region.The AraC protein had two cAMP and cGMP dependent protein kinase phosphorylation site,five protein kinase C phosphorylation sites,three casein kinase II phosphorylation sites,one prenyl group binding site(CAAX box)and five microbodies C-terminal targeting signal.The predicted results of protein subcellular localization showed that AraC was located in the mitochondria,nucleus and cytoplasm.Its protein is unstable and hydrophilic.The AraC protein is a transcriptional regulatory protein which belongs to HTH_18 superfamily.According to the prediction,secondary structure:a-helix(Alpha helix)accounted for 52.12%,random coil(31.78%),extended strand(11.02%),b-fold(Beta turn)accounted for 5.08%.V.alginolyticus,Vibrio parahaemolyticus and Vibrio palustris were clustered together,which implies that the genetic relationship between these three species was the closest. | Fangling MO Gyamfua AFRIYIE Jialing HU Junling WANG Shihui ZHOU Zhongduo WANG F.K.A.KUEBUTORNYE Chuanhao PAN Huanying PANG | 2021 | Asian Agricultural Research2021，13，2： | 0 |
