| 1 | Validation of novel hub genes and molecular mechanisms in acute lung injury using an integrative bioinformatics approach显示文摘Acute lung injury(ALI)is an inflammatory pulmonary disease that can easily develop into serious acute respiratory distress syndrome,which has high morbidity and mortality.However,the molecular mechanism of ALI remains unclear,and few molecular biomarkers for diagnosis and treatment have been identified.In this study,we aimed to identify novel molecular biomarkers using a bioinformatics approach.Gene expression data were obtained from the Gene Expression Omnibus database,co-expressed differentially expressed genes(CoDEGs)were identified using R software,and further functional enrichment analyses were conducted using the online tool Database for Annotation,Visualization,and Integrated Discovery.A protein-protein interaction network was established using the STRING database and Cytoscape software.Lipopolysaccharide(LPS)-induced ALI mouse model was constructed and verified.The hub genes were screened and validated in vivo.The transcription factors(TFs)and miRNAs associated with the hub genes were predicted using the NetworkAnalyst database.In total,71 CoDEGs were screened and found to be mainly involved in the cytokine-cytokine receptor interactions,and the tumor necrosis factor and malaria signaling pathways.Animal experiments showed that the lung injury score,bronchoalveolar lavage fluid protein concentration,and wet-to-dry weight ratio were higher in the LPS group than those in the control group.Real-time polymerase chain reaction analysis indicated that most of the hub genes such as colony-stimulating factor 2(Csf2)were overexpressed in the LPS group.A total of 20 TFs including nuclear respiratory factor 1(NRF1)and two miRNAs were predicted to be regulators of the hub genes.In summary,Csf2 may serve as a novel diagnostic and therapeutic target for ALI.NRF1 and mmu-mir-122-5p may be key regulators in the development of ALI. | Qingchun Liang Qin Zhou Jinhe Li Zhugui Chen Zhihao Zhang Ruimeng Liu Haicheng Huang Zhiyong Peng Youtan Liu | 2021 | Acta Biochimica et Biophysica Sinica2021，53，3： | 1 |
| 2 | Constituent Isomerism-Induced Quasicrystal and Frank-KasperσSuperlattices Based on Nanosized Shape Amphiphiles显示文摘Naturally,subtle variations in the chemical structures of constituent molecules may significantly affect their multiscale spatial arrangements,properties,and functions.Deceptively simple spherical assemblies supply an ideal platform to investigate how subtle chemical differences affect hierarchically assembled structures.Here,the authors report two sets of nanosized shape amphiphiles,which were constructed by a triphenylene core and six polyhedral oligomeric silsesquioxane cages peripherally grafted through linkers.The slight differences in these samples are merely several methylene units in their linkers,including several pairs of constituent isomers.These nanosized shape amphiphiles self-assemble into a variety of unconventional spherical packing structures,which include the Frank-Kasperσphase and dodecagonal quasicrystal.Several types of unconventional phase transitions were systematically investigated.The authors alternated the conventional columnar phases of discotic molecules to unconventional spherical packing phases.These unconventional structures may shed light into discovering discotic mesogens-based materials with new properties and functions. | Zebin Su Jiahao Huang Wenpeng Shan Xiao-Yun Yan Ruimeng Zhang Tong Liu Yuchu Liu Qing-Yun Guo Fenggang Bian Xiaran Miao Mingjun Huang Stephen Z.D.Cheng | 2021 | CCS Chemistry2021，3，5： | 0 |
