Essential role of the coxsackie- and adenovirus receptor (CAR) in development of the lymphatic system in mice.

The coxsackie- and adenovirus receptor (CAR) is a cell adhesion molecule predominantly associated with epithelial tight junctions in adult tissues. CAR is also expressed in cardiomyocytes and essential for heart development up to embryonic day 11.5, but not thereafter.

Multiple phenotypes in adult mice following inactivation of the Coxsackievirus and Adenovirus Receptor (Car) gene.

To determine the normal function of the Coxsackievirus and Adenovirus Receptor (CAR), a protein found in tight junctions and other intercellular complexes, we constructed a mouse line in which the CAR gene could be disrupted at any chosen time point in a broad spectrum of cell types and tissues. All knockouts examined displayed a dilated intestinal tract and atrophy of the exocrine pancreas with appearance of tubular complexes characteristic of acinar-to-ductal metaplasia. The mice also exhibited a complete atrio-ventricular block and abnormal thymopoiesis.

A SNAIL1-SMAD3/4 transcriptional repressor complex promotes TGF-beta mediated epithelial-mesenchymal transition.

Epithelial-mesenchymal transition (EMT) is essential for organogenesis and is triggered during carcinoma progression to an invasive state. Transforming growth factor-beta (TGF-beta) cooperates with signalling pathways, such as Ras and Wnt, to induce EMT, but the molecular mechanisms are not clear. Here, we report that SMAD3 and SMAD4 interact and form a complex with SNAIL1, a transcriptional repressor and promoter of EMT.

Auditive identification of signal-processed environmental sounds: monitoring the environment.

The goal of the present study was to compare six transposing signal-processing algorithms based on different principles (Fourier-based and modulation based), and to choose the algorithm that best enables identification of environmental sounds, i.e. improves the ability to monitor events in the surroundings.

The coxsackie- and adenovirus receptor (CAR) is an in vivo marker for epithelial tight junctions, with a potential role in regulating permeability and tissue homeostasis.

The coxsackie- and adenovirus receptor (CAR) is a transmembrane protein belonging to the immunoglobulin superfamily. The function of CAR as a virus receptor has been extensively analyzed, while its physiological role and expression pattern in adult tissues have remained less clear. CAR associates with epithelial tight junctions in vitro and mediates cell-cell adhesion.

Coxsackievirus and adenovirus receptor (CAR) is expressed in male germ cells and forms a complex with the differentiation factor JAM-C in mouse testis.

The coxsackievirus and adenovirus receptor (CAR) is a transmembrane protein important for viral binding to target cells. Using RT-PCR, Western analysis, GST pull-down assay and indirect immunofluorescence, it was shown that CAR is expressed in male germ cells from mice, rats, and humans. CAR was detected in round spermatids in the testis as well as in purified, mature spermatozoa.

The cell surface protein coxsackie- and adenovirus receptor (CAR) directly associates with the Ligand-of-Numb Protein-X2 (LNX2).

The coxsackievirus and adenovirus receptor (CAR) is a cell surface protein that is proposed to be involved in cell-cell adhesion. Based on a yeast two-hybrid screen, co-immunoprecipitation and binding experiments, the intracellular tail of CAR was found to interact both in vivo and in vitro with the Ligand-of-Numb Protein-X2 (LNX2). The interacting domains between the two proteins were identified by truncation analyses and affinity chromatography.

Expression of the coxsackie and adenovirus receptor in human astrocytic tumors and xenografts.

The sensitivity of human tissues and tumors to infection with type C adenoviruses correlates with the expression of the human coxsackie B- and adenovirus receptor, hCAR. HCAR is heterogeneously expressed in various tissues and types of human cancer cells, which has implications for the use of adenoviruses as vectors in cancer gene therapy. Using immunoblotting, real-time PCR, FACS-analysis and sensitivity to infection with adenovirus-lacZ, we analyzed the expression level of hCAR in glioma Grade IV cell lines.

The Coxsackievirus and adenovirus receptor (CAR) forms a complex with the PDZ domain-containing protein ligand-of-numb protein-X (LNX).

The Coxsackievirus and adenovirus receptor (CAR) functions as a virus receptor, but its primary biological function is unknown. A yeast two-hybrid screen was used to identify Ligand-of-Numb protein-X (LNX) as a binding partner to the intracellular tail of CAR. LNX harbors several protein-protein interacting domains, including four PDZ domains, and was previously shown to bind to and regulate the expression level of the cell-fate determinant Numb.
