The Zonula Occludens proteins ZO-1 and ZO-2 are cell-cell junction-associated adaptor proteins that are essential for the structural and regulatory functions of tight junctions in epithelial cells and their absence leads to early embryonic lethality in mouse models. Here, we use the embryoid body, an in vitro peri-implantation mouse embryogenesis model, to elucidate and dissect the roles ZO-1 a...
Zonula occludens (ZO)-1 is a multi-domain scaffold protein known to have critical roles in the establishment of cell-cell adhesions and the maintenance of stable tissue structures through the targeting, anchoring, and clustering of transmembrane adhesion molecules and cytoskeletal proteins. Here, we report that ZO-1 directly binds to MRCKβ, a Cdc42 effector kinase that modulates cell protrusion...
AIMS Remodelling of gap junctions, involving reduction of total gap junction quantity and down-regulation of connexin43 (Cx43), contributes to the arrhythmic substrate in congestive heart failure. However, little is known of the underlying mechanisms. Recent studies from in vitro systems suggest that the connexin-interacting protein zonula occludens-1 (ZO-1) is a potential mediator of gap junct...
Due to the availability of limited water resources in the country, it is necessary to use unconventional water. On the other hand, application of minerals such as Zeolite (Zo) is necessary to simulate plant growth and reduce the harmful effects of wastewater. The present study was conducted to investigate the effect of irrigation by wastewater with Zo on cotton (Gossypium herbaceum) based on a ...
The molecular mechanisms of how primordial adherens junctions (AJs) evolve into spatially separated belt-like AJs and tight junctions (TJs) during epithelial polarization are not well understood. Previously, we reported the establishment of ZO-1/ZO-2-deficient cultured epithelial cells (1[ko]/2[kd] cells), which lacked TJs completely. In the present study, we found that the formation of belt-li...
ZO-1, ZO-2, and ZO-3 are closely related scaffolding proteins that link tight junction (TJ) transmembrane proteins such as claudins, junctional adhesion molecules, and occludin to the actin cytoskeleton. Even though the zonula occludens (ZO) proteins are among the first TJ proteins to have been identified and have undergone extensive biochemical analysis, little is known about the physiological...
OBJECTIVE The aim of this study was to investigate the expression of Zonula Occludens-1 (ZO-1) and its potential value as prognostic indicator of survival in patients with primary non-small cell lung cancer (NSCLC). METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry with tissue microarrays were used to characterize the expression of the ZO-1 mRNA and p...
Effects of Interleukin-13 and Montelukast on the Expression of Zonula Occludens-1 in Human Podocytes
PURPOSE The aim of this study was to investigate whether pathologic changes in zonula occludens-1 (ZO-1) are induced by interleukin-13 (IL-13) in the experimental minimal-change nephrotic syndrome (MCNS) model and to determine whether montelukast, a leukotriene receptor antagonist, has an effect on ZO-1 restoration in cultured human podocytes. MATERIALS AND METHODS Human podocytes cultured on...
