PLEKHA7 modulates epithelial tight junction barrier function
PLEKHA7 is a recently identified protein of the epithelial zonula adhaerens (ZA), and is part of a protein complex that stabilizes the ZA, by linking it to microtubules. Since the ZA is important in the assembly and disassembly of tight junctions (TJ), we asked whether PLEKHA7 is involved in modulating epithelial TJ barrier function. We generated clonal MDCK cell lines in which one of four diff...
متن کاملTight Junction in Ovarian Surface Epithelium and Epithelial Ovarian Tumors
Zhu, Yihong. 2007. Tight Junction in Ovarian Surface Epithelium and Epithelial Ovarian Tumors. Department of Obstetrics and Gynecology, Sahlgrenska Academy at Göteborg University, Sahlgrenska University Hospital SE-413 45 Göteborg, Sweden. Epithelial ovarian cancer originating from ovarian surface epithelium (OSE) is the most lethal type of gynecological cancer among women worldwide. The poor u...
متن کاملGalpha12 regulates protein interactions within the MDCK cell tight junction and inhibits tight-junction assembly.
The polarized functions of epithelia require an intact tight junction (TJ) to restrict paracellular movement and to separate membrane proteins into specific domains. TJs contain scaffolding, integral membrane and signaling proteins, but the mechanisms that regulate TJs and their assembly are not well defined. Galpha12 (GNA12) binds the TJ protein ZO-1 (TJP1), and Galpha12 activates Src to incre...
متن کاملCPEB mediated ZO-1 mRNA Localization is Required for Epithelial Tight Junction Assembly and Cell Polarity
CPEB is a translational regulatory sequence-specific RNA-binding protein that controls germ cell development. Here we show that CPEB heterozygous female mice are fertile but contain disorganized mammary epithelial cells, in which zonal occludens-1 and claudin-3, apical tight-junction proteins, are mislocalized. CPEB depletion from mammary epithelial cells disrupts zonal occludens-1 apical local...
متن کاملTight junction properties of the immortalized human bronchial epithelial cell lines Calu-3 and 16HBE14o-.
Tight junctions (TJs) make a vital contribution to the barrier properties of the airway lining. Opening of TJs, or their frank cleavage, is suspected as a pathophysiological event in the lung, but research into the cellular and molecular mechanisms involved has been impeded by technical limitations of available experimental models. The authors have compared the properties of two epithelial cell...
