Pełny tekst źródłaThe E3 ubiquitin ligase HACE1 is a key regulator of cellular homeostasis best-characterized for its ability to control the activity of the Rho GTPase Rac1. This GTPase is encoded by an essential gene whose product controls a wide array of cellular processes such as cell adhesion, migration and proliferation. Accordingly, the repression of HACE1 expression due to genetic and epigenetic alterations has been associated with numerous pathologies, including cancer, neurodegenerative and developmental diseases. However, nothing is known about the posttranslational regulation of HACE1 activity. Here, we unveiled that HACE1 gets phosphorylated at serine Ser-385 by Group-I Pak kinases in response to Rac1/Cdc42 activation. Mechanistically, we define that the phospho-mimetic mutant HACE1(S385E) displays a lower capacity to ubiquitinate Rac1 in cells. In addition, our work attributes to the phosphorylation of Ser-385 a pivotal role in the state of HACE1 oligomerization, which sets the basis for deciphering the relationship between HACE1 structure and activity. In parallel, we have found that the loss of HACE1 expression leads to the disruption of epithelial monolayer cohesion characterized by disrupted of cell-cell junctions. Accordingly, we determined that loss of HACE1 results in the acquisition of epithelial-mesenchymal transition (EMT) features, including a transcriptionally regulated switch of expression between E-cadherin and N-cadherin. Altogether, this work reveals a phospho-mediated regulation of HACE1 activity that is under the control of Group I PAKs and implicates HACE1 in the balance between epithelium integrity versus EMT

Pełny tekst źródłaTo maintain epithelial tissue organisation and polarity, new cell-cell junctions need to be formed upon cell division. To understand the mechanisms of junction formation during cytokinesis, we explored in Drosophila epithelial tissues, the de novo formation of tricellular septate junctions (TCJs), which are critical to tissue barrier function, stem cell homeostasis and mitotic spindle orientation. During the final stages of cytokinetic ring constriction, the membranes of the two daughter cells and of the neighbouring cells located below the adherens junction (AJ) remain entangled in a 4-cell structure apposed to the midbody. Protein constituents of the septate junction Discs-large (Dlg) and Neuroglian (Nrg) and the components of the TCJ Gliotactin (Gli) and Anakonda (Aka) accumulate in this 4-cell structure. Subsequently, a basal descent of the midbody correlates with the detachment of the neighbouring cell membranes, disengagement of the daughter cells from their neighbours and the formation of mature TCJs. The detachment of the neighbouring cells from the midbody is independent of abscission. On the contrary, the loss of Gli or Aka function prevents the resolution of the connection between the daughter-neighbour cells and the midbody movement. Altogether, we propose that TCJ proteins control an additional step of cytokinesis necessary for the disentanglement of the daughter cells and their neighbours during epithelial cytokinesis

Pełny tekst źródłaControl of cell polarity is crucial during tissue morphogenesis and renewal and depends on spatial cues provided by the extracellular environment. In isolated cells, the geometry of interactions with the extracellular matrix has been shown to control intracellular asymmetry. Using micropatterned substrates to impose reproducible cell-cell interactions, we show the that cell-cell contacts provide polarizing cues that regulate intracellular organization and cell orientation. In a variety bf cell types, Including astrocytes, epithelial and endothelial cells, calcium-dependent cadherin-mediated cell-cell interactions induce nucleus and centrosome off-centring towards cell-cell contacts and promote orientation of the nucleus-centrosome axis towards free cell edges. Nucleus and centrosome off-centring is controlled by N-cadherin and ß-catenin through the regulation of cell interactions with the extracellular matrix and the regulation of the actin and intermediate filaments cytoskeletons. Moreover, N-cadherin and a and ß-catenins control directly the orientation of the nucleus-centrosome axis in a microtubule-dependent manner. Our results demonstrate that in addition to the specific function of E-cadherin in regulating baso-apical epithelial polarity, classical cadherins can induce cell polarization in otherwise non-polarized cells. Cadherins are likely to be critical determinants of the orientation of cell migration and cell division during organogenesis as well as in adult tissues

Pełny tekst źródłaThe ZEBRA (EB1) transcription factor of Epstein-Barr virus (EBV) is crucial for initiation of lytic infection and viral production. Ubinuclein (Ubn-1) has been identified as a cellular partner of ZEBRA enabling to prevent ZEBRA-DNA interaction. The role of Ubn-1 in the cell remains elusive as well as the consequences of its interaction with ZEBRA in EBV infected cells. In our work, we have characterized Ubn-1 as a new protein of epithelial cells tight junctions (TJ) and a new member of NACos (nuclear and adhesion complex components) proteins with a dual cellular localisation, the nuclei and the junctions of the cells. Using a proteomic approach coupled to mass spectrometry, we have then studied interacting partners of Ubn-1 in order to get more insights on its role in epithelial cells and identified LYRIC and RACK-1 proteins. Our results suggest that Ubn-1 is involved in different biological processes such regulation of cells proliferation and cell-cell contacts. Finally, in EBV infected epithelial cells, Ubn-1 functions seem depend on its cellular localisation. Nuclear Ubn-1 regulates negatively lytic cycle and virus production interfering with ZEBRA and others cellular factors in the activation of AP-1 promoters. When Ubn-1 is sequestered in TJ, Ubn-1 can no longer act as a repressor of ZEBRA which is free to activate the EBV productive cycle
