ABSTRACT Epithelial cells polarize in response to contacts with the extracellular matrix and with neighboring cells. Interac-tions of cells with the extracellular matrix are mediated mainly by the integrin family of receptors. To begin to understand the role of integrins in polarization, we have investigated the expression and ...

Quantitative proteomic analysis of MDCK cell adhesion
Molecular Omics, 2020Abstract MDCK cells are a key reagent in modern vaccine production. As MDCK cells are normally adherent, creation of suspension cells for vaccine production using genetic engineering approaches is highly desirable. However, little is known regarding the mechanisms and effectors underlying MDCK cell adhesion.

Electrical properties of cultured epithelioid cells (MDCK)
The Journal of Membrane Biology, 1983This is a study of the intracellular electrical potential, membrane resistance, and capacity of MDCK cells (epithelioid of renal origin) cultured in monolayers on a collagen couch. These monolayers have a transepithelial resistance of 256 +/- 12 (22) ohm cm2 (mean +/- standard error, and number of observations), and the cells have 61.6 +/- 6.3 (92) M ...

Influence of glucose on the toxicity of oxophenylarsine in MDCK cells
Archives of Toxicology, 1995Trivalent arsenicals like oxophenylarsine (PhAsO) inhibit cellular pyruvate dehydrogenase, thus leading to a drop of acetylCoA formation and a slow-down of the citric acid cycle. Glucose may protect cells from arsenic toxicity, because increased glycolysis may prevent fatal shortage of ATP.

Methods for Establishing Rab Knockout MDCK Cells
2021The Rab family small GTPases are key regulators of intracellular membrane traffic that are conserved in all eukaryotic cells. Rabs are thought to regulate various steps of membrane traffic, including the budding, transport, tethering, docking, and fusion of vesicles or organelles.

The use of monolayers of MDCK cells as a model system for natural transporting epithelia created the necessity of learning about their ion-translocating mechanisms. These mechanisms have been analyzed directly by measuring unidirectional fluxes of tracers, and indirectly through their consequences on electrical parameters and blister-forming activity ...

In polarized cells the plasma membrane is divided into apical and basolateral domains. Membrane is internalized from both these domains and the internalized components can follow several different routes, for example, they can be transported to the opposite domain of the cell (transcytosis), routed to lysosomes or recycled back to the same domain ...

Polarized trafficking of thyrocyte proteins in MDCK cells
Molecular and Cellular Endocrinology, 2002Recent studies suggest striking similarities between polarized protein sorting in thyrocytes and MDCK epithelial cells, including apical trafficking of thyroglobulin (Tg), thyroid peroxidase, and aminopeptidase N; as well as basolateral targeting of heparan sulfate proteoglycans, thrombospondin 1 (TSP1), type 1 5'-deiodinase, sodium-potassium ATPase ...

Anion channels for amino acids in MDCK cells
American Journal of Physiology-Cell Physiology, 1992Large losses of amino acids by diffusion were previously observed in Madin-Darby canine kidney (MDCK) cells during volume regulation. Also, an outward rectifying anion channel was activated. Because this channel was not selective among anions, it was suggested that it could be permeable to amino acids.

Polarized exocytosis in mdck cells is regulated by phosphorylation
Journal of Cell Science, 1995ABSTRACT Protein phosphorylation and dephosphorylation systems modulate many cellular activities and have recently been implicated in the in vitro transport of newly synthesized proteins. Here we show that polarized transport from the Golgi to the plasma membrane in intact MDCK cells is regulated by phosphorylation-dephosphorylation ...
