    Identification of <t>fibronectin</t> as an α4β7 binding component of CHO cell proteins. The CHO cell proteins were labeled with 125I. (A) Comparison of proteins detected by autoradiography to 25 μg of proteins stained with Coomassie blue. Five major bands present in the Coomassie-stained gel were also identified by autoradiography, as indicated. (B) Proteins displayed α4β7-dependent binding to RPMI88666 cells after radiolabeling. (C) RPMI8866 cells were used to capture and identify α4β7 components. 125I-labeled protein was captured on cells in the presence or absence of MAb 2B4, and then the cell-bound material was dissociated and analyzed. Input protein was compared to cell-bound material by SDS-PAGE and autoradiography. Shown are the original autoradiograph and a contrast-enhanced image. The cells retained a major band of approximately 260 kDa and a minor band of 55 kDa.

    Heparin inhibits fibronectin-mediated gp120-α4β7 binding. 1086.d7 gp120 was incubated for 2 h with CHO cell proteins. Heparin sulfate or chondroitin sulfate was added at the indicated concentrations 10 min prior to incubation with RPMI8866 cells. The results are the means and standard deviations of three replicates; the red line is a best-fit curve of the heparin inhibition data.

    The recombinant human fibronectin fragment retronectin mediates gp120-α4β7 binding. (A) Plasma fibronectin, cellular fibronectin, and retronectin were biotinylated and tested for binding to RPMI8866 cells. The results of a single representative experiment are shown. (B) Western blot analysis of plasma fibronectin (pFn), cellular fibronectin (cFn), and retronectin. Shown are two parallel blots developed with either polyclonal fibronectin antiserum or monoclonal antibody to the fibronectin CS1 peptide; 1 μg of protein was loaded per lane. (C) Retronectin mediates gp120 binding to RPMI8866 cells. Biotinylated retronectin (+biotin) produces a binding signal, and nonbiotinylated retronectin (−biotin) does not. Binding of wild-type MW959 and MW959 with the V2 loop deleted was measured with (hatched bars) and without (solid bars) 2-h preincubation with retronectin. The results are the means and standard deviations of 3 replicate measures.
