In the preceding paper (Pesonen M., W. Ansorge, and K. Simons, 1984, J. Cell Biol., 99:796-802), we have shown that transcellular transport of the membrane glycoprotein G of vesicular stomatitis virus implanted into the apical membrane of Madin-Darby canine kidney cells is transcytosed through the endosomal compartment to the basolateral plasma membrane. To determine whether the Golgi complex was involved in this process, G protein lacking sialic acid or all of the terminal sugars was implanted into the apical membrane and allowed to move to the basolateral membrane. Using the criteria of endoglycosidase H sensitivity, binding to Ricinus communis agglutinin and two-dimensional gel electrophoresis, the sugars on the transcytosed G protein were found to be the same as in the starting material. The absence of any involvement of the Golgi complex in transcytosis was supported by subcellular fractionation studies in which transcytosing G protein was never found in fractions containing galactosyl transferase.

The G protein of vesicular stomatitis virus, implanted into the apical plasma membrane of Madin-Darby canine kidney cells, is rapidly transcytosed to the basolateral membrane. In this and the accompanying paper (Pesonen, M., R. Bravo, and K. Simons, 1984, J. Cell Biol. 99:803-809.) we have studied the intracellular route by which the G protein traverses during transcytosis. Using Percoll density gradient centrifugation and free flow electrophoresis we could demonstrate that the G protein is endocytosed into a nonlysosomal compartment with a density of approximately 1.05 g/cm3, which has many of the characteristics of endosomes. Transcytosis to the basolateral membrane appeared to occur from this compartment. No direct evidence for the involvement of lysosomes in the transcytotic route could be obtained. No G protein was detected in the lysosomes when transcytosis of G protein was occurring. Moreover, at 21 degrees C when passage of G protein to the lysosomes was shown to be arrested, transcytosis of G protein could still be demonstrated.

The polarity of the surface distribution of viral glycoproteins during virus infection has been studied in the Madin-Darby canine kidney epithelial cell line on nitrocellulose filters. Using a surface radioimmunoassay on Madin-Darby canine kidney strain I cells that had been infected with vesicular stomatitis virus or with avian influenza fowl plague virus, we found that the surface G protein was 97% basolateral, whereas the fowl plague virus hemagglutinin was 88% apical. Newly synthesized, pulse-labeled vesicular stomatitis virus appeared first on the basolateral plasma membrane as measured by an immunoprecipitation assay in which the anti-G protein antibody was applied to the monolayer either from the apical or the basolateral side. Labeled G protein could be accumulated inside the cell at a late stage of transport by decreasing the temperature to 20 degrees C during the chase. Reversal to 37 degrees C led to its rapid and synchronous transport to the basolateral surface at an initial rate 61-fold greater than that of transport to the apical side. These results demonstrate that the newly synthesized G protein is transported directly to the basolateral membrane and does not pass over the apical membrane en route. Since a previous study of the surface appearance of influenza virus hemagglutinins showed that the newly synthesized hemagglutinins were inserted directly from an intracellular site into the apical membrane (Matlin, K., and K. Simons, 1984, J. Cell Biol., 99:2131-2139), we conclude that the divergence of the transport pathway for the apical and basolateral viral glycoproteins has to occur intracellularly, i.e., before reaching the cell surface.

The G protein of vesicular stomatitis virus was implanted in the apical plasma membrane of Madin-Darby canine kidney cells by low pH-dependent fusion of the viral envelope with the cellular membrane. The amount of fusion as determined by removal of unfused virions, either by tryptic digestion or by EDTA treatment at 0 degree C, was 22-24% of the cell-bound virus radioactivity. Upon incubation of cells after implantation, the amount of G protein as detected by immunofluorescence diminished on the apical membrane and appeared within 30 min on the basolateral membrane. At the same time some G protein fluorescence was also seen in intracellular vacuoles. The observations by immunofluorescence were confirmed and extended by electron microscopy. Using immunoperoxidase localization, G protein was seen to move into irregularly shaped vacuoles (endosomes) and multivesicular bodies and to appear on the basolateral plasma membrane. These results suggest that the apical and basolateral domains of Madin-Darby canine kidney cells are connected by an intracellular route.

The two centrioles that are localized close to each other and to the nucleus in single Madin-Darby Canine kidney cells (MDCK) move apart by distances as large as 13 microns after the establishment of extensive cellular junctions. Microfilaments, and possibly microtubules appear to be responsible for this separation. In fully polarized cells, the centrioles are localized just beneath the apical membrane. After disruption of intercellular junctions in low calcium medium, the centrioles move back towards the cell center. This process requires intact microtubules but happens even in the absence of microfilaments. These results indicate that the position of centrioles is determined by opposing forces produced by microtubules and microfilaments and suggest that the balance between these forces is modulated by the assembly of cellular junctions. Centriole separation appears to be an early event in the process that precedes their final positioning in the apical-most region of the polarized cell.

Polarized epithelial cells maintain the asymmetric composition of their apical and basolateral membrane domains by at least two different processes. These include the regulated trafficking of macromolecules from the biosynthetic and endocytic pathway to the appropriate membrane domain and the ability of the tight junction to prevent free mixing of membrane domain-specific proteins and lipids. Cdc42, a Rho family GTPase, is known to govern cellular polarity and membrane traffic in several cell types. We examined whether this protein regulated tight junction function in Madin-Darby canine kidney cells and pathways that direct proteins to the apical and basolateral surface of these cells. We used Madin-Darby canine kidney cells that expressed dominant-active or dominant-negative mutants of Cdc42 under the control of a tetracycline-repressible system. Here we report that expression of dominant-active Cdc42V12 or dominant-negative Cdc42N17 altered tight junction function. Expression of Cdc42V12 slowed endocytic and biosynthetic traffic, and expression of Cdc42N17 slowed apical endocytosis and basolateral to apical transcytosis but stimulated biosynthetic traffic. These results indicate that Cdc42 may modulate multiple cellular pathways required for the maintenance of epithelial cell polarity.

The synchronized directed transfer of the envelope glycoproteins of the influenza and vesicular stomatitis viruses from the Golgi apparatus to the apical and basolateral surfaces, respectively, of polarized Madin-Darby canine kidney (MDCK) cells can be achieved using temperature-sensitive mutant viruses and appropriate temperature shift protocols (Rindler, M. J., I. E. Ivanov, H. Plesken, and D. D. Sabatini, 1985, J. Cell Biol., 100:136-151). The microtubule-depolymerizing agents colchicine and nocodazole, as well as the microtubule assembly-promoting drug taxol, were found to interfere with the normal polarized delivery and exclusive segregation of hemagglutinin (HA) to the apical surface but not with the delivery and initial accumulation of G on the basolateral surface. Immunofluorescence analysis of permeabilized monolayers of influenza-infected MDCK cells treated with the microtubule-acting drugs demonstrated the presence of substantial amounts of HA protein on both the apical and basolateral surfaces. Moreover, in cells infected with the wild-type influenza virus, particles budded from both surfaces. Viral counts in electron micrographs showed that approximately 40% of the released viral particles accumulated in the intercellular spaces or were trapped between the cell and monolayer and the collagen support as compared to less than 1% on the basolateral surface of untreated infected cells. The effect of the microtubule inhibitors was not a result of a rapid redistribution of glycoprotein molecules initially delivered to the apical surface since a redistribution was not observed when the inhibitors were added to the cells after the HA was permitted to reach the apical surface at the permissive temperature and the synthesis of new HA was inhibited with cycloheximide. The altered segregation of the HA protein that occurs may result from the dispersal of the Golgi apparatus induced by the inhibitors or from the disruption of putative microtubules containing tracks that could direct vesicles from the trans Golgi apparatus to the cell surface. Since the vesicular stomatitis virus G protein is basolaterally segregated even when the Golgi elements are dispersed and hypothetical tracks disrupted, it appears that the two viral envelope glycoproteins are segregated by fundamentally different mechanisms and that the apical surface may be incapable of accepting vesicles carrying the G protein.

Monolayers of Madin-Darby Canine Kidney (MDCK) cells grown on permeable filters generated lactate aerobically and accumulated it preferentially in the basolateral compartment, suggesting the presence of a lactate carrier. The mechanism of lactate transport across apical and basolateral membranes was examined by determining intracellular pH (pHi) microspectrofluorimetrically after addition of lactate to the extracellular solutions and by measuring uptake of [14C]lactate. Addition of 20 mM lactate to the apical compartment produced no change in pHi, whereas lactate added to the basolateral compartment rapidly and reversibly lowered pHi. Pyruvate produced similar results. Inhibitors of lactate/H+ co-transporters, alpha-cyano-4-hydroxycinnamate (CnCN) and quercetin, partially inhibited the fall in pHi produced by basolateral lactate. In contrast, the disulphonic stilbene. DIDS (4,4′-di-isothiocyanostilbene-2,2′-disulphonic acid) produced no inhibition at 0.5 mM. Kinetic analysis was performed by applying basolateral lactate at various concentrations and measuring the rate of entry (delta pHi/min) in the presence and absence of CnCN. Lactate flux was shown to occur by both non-ionic diffusion and a alpha-cyano-4-hydroxycinnamate-sensitive component (carrier). The latter has a Km of approximately 7 mM for the lactate anion. Propionate, but not formate, lowered pHi to the same degree as did equimolar lactate, but the propionate effect was not inhibited by CnCN. Influx of [14C]lactate was substantially greater across the basolateral membrane than across the apical membrane and occurred in the absence of Na+. We conclude that MDCK cells grown on permeable filters generate lactate aerobically and transport it across the basolateral membrane by way of a lactate/H+ cotransporter.

Glycosylation has been shown to be important for proper routing and membrane insertion of a number of proteins. In the collecting duct, aquaporin-2 (AQP2) is inserted into the apical membrane after stimulation of vasopressin type-2 receptors and retrieved into an endosomal compartment after withdrawal of vasopressin. The extent of glycosylation of AQP2 in human kidney and urine and the effects of deglycoylation on routing of AQP2 in an AQP2-transfected Madin-Darby canine kidney cell line (clone WT10) were investigated. Semiquantitative immunoblotting of human kidney membranes and urine showed an AQP2 glycosylation of 35 to 45% for medulla, papilla, and urine, with low variation among individuals. The 1-desamino-8-D-arginine vasopressin-induced transcellular osmotic water permeability (Pf) of WT10 cells by a factor of 2.6 +/- 0.2 was reduced to 1.5 +/- 0.1 after pretreatment with the glycosylation inhibitor tunicamycin. However, when WT10 cells were incubated with 8-br-cAMP, the Pf increased by a factor 2.8 +/- 0.2 and by 2.9 +/- 0.2 after prior incubation with tunicamycin. Immunoblot analyses revealed that in WT10 cells, 34% of AQP2 is glycosylated, which was reduced to 2% after tunicamycin treatment. Surface biotinylation and subsequent semiquantitative immunoblotting revealed that stimulation by cAMP increased the level of AQP2 in the apical membrane of WT10 cells 1.5-fold. independent of the presence of tunicamycin. However, in tunicamycin-treated WT10 cells, all AQP2 in the apical membrane was unglycosylated, whereas in untreated cells 30% of AQP2 in the apical membrane was glycosylated. These results prove that glycosylation has no function in the routing of AQP2 in Madin-Darby canine kidney cells.
