| 1 | Modeling of COVID-19 disease disparity in gastric organoids reveals the spatiotemporal dynamics of SARS-CoV-2 infectivity显示文摘Dear Editor,The promptness and continuous expansion of the coronavirus disease 2019(COVID-19)pandemic,elicited by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and its variants,has presented an unprecedented impact on human health(WHO Coronavirus(COVID-19)Dashboard,2021).Although vaccination has attenuated the severe symptoms,there is no specific antiviral medication available for preventing the viral spread(Drayman et al.,2021). | Wenwen Wang Fengrui Yang Jie Lin Saravanakumar Muthusamy Shihao Du McKay Mullen Fatima Garba Wanjuan Wang Xu Liu Tao Li Zhihong Yang Xia Ding Felix Aikhionbare Xinjiao Gao Zhikai Wang Xing Liu Xuebiao Yao | 2022 | Journal of Molecular Cell Biology2022，14，2： | 1 |
| 2 | The septin complex links the catenin complex to the actin cytoskeleton for establishing epithelial cell polarity显示文摘Cell polarity is essential for spatially regulating of physiological processes in metazoans by which hormonal stimulation‒secretion coupling is precisely coupled for tissue homeostasis and organ communications.However,the molecular mechanisms underlying epithelial cell polarity establishment remain elusive.Here,we show that septin cytoskeleton interacts with catenin complex to organize a functional domain to separate apical from basal membranes in polarized epithelial cells.Using polarized epithelial cell monolayer as a model system with transepithelial electrical resistance as functional readout,our studies show that septins are essential for epithelial cell polarization.Our proteomic analyses discovered a novel septin‒catenin complex during epithelial cell polarization.The functional relevance of septin‒catenin complex was then examined in three-dimensional(3D)culture in which suppression of septins resulted in deformation of apical lumen in cysts,a hallmark seen in polarity-deficient 3D cultures and animals.Mechanistically,septin cytoskeleton stabilizes the association of adherens catenin complex with actin cytoskeleton,and depletion or disruption of septin cytoskeleton liberates adherens junction and polarity complexes into the cytoplasm.Together,these findings reveal a previously unrecognized role for septin cytoskeleton in the polarization of the apical‒basal axis and lumen formation in polarized epithelial cells. | Xueying Wang Wenwen Wang Xiwei Wang Ming Wang Lijuan Zhu Fatima Garba Chuanhai Fu Barbara Zieger Xu Liu Xing Liu Xuebiao Yao | 2021 | Journal of Molecular Cell Biology2021，13，6： | 1 |
