A human monoclonal autoantibody to breast cancer identifies the PDZ domain containing protein GIPC1 as a novel breast cancer-associated antigen-3

St epithelium cell line HBL100 and breast cancer cell lines MCF-7, T47D, SK-BR-3, MDA231, MDA157 and MDA453. A probe for the GAPDH gene was used to normalize expression. Panel B: Densitometry analysis of the Northern blot was performed to quantitate the mRNA expression. The data indicates that the GIPC1 gene is upregulated in breast cancer cell lines.<p><b>Copyright information:</b></p><p>Taken from "A human monoclonal autoantibody to breast cancer identifies the PDZ domain containing protein GIPC1 as a novel breast cancer-associated antigen"</p><p>http://www.biomedcentral.com/1471-2407/8/248</p><p>BMC Cancer 2008;8():248-248.</p><p>Published online 24 Aug 2008</p><p>PMCID:PMC2529336.</p><p></p

This suggests that two populations of GIPC1 molecules exist in these cells and may be related to the protein doublet identified by Western blot analysis in Figure 2.<p><b>Copyright information:</b></p><p>Taken from "A human monoclonal autoantibody to breast cancer identifies the PDZ domain containing protein GIPC1 as a novel breast cancer-associated antigen"</p><p>http://www.biomedcentral.com/1471-2407/8/248</p><p>BMC Cancer 2008;8():248-248.</p><p>Published online 24 Aug 2008</p><p>PMCID:PMC2529336.</p><p></p

displayed. Human Ig H and L chains are present in the tissue and are recognized by the secondary anti-human antiserum. The target antigen is detected as a doublet in both the breast cancer tissue and SK-BR-3 cell line but is not detected in normal breast tissue. Both bands in the doublet are present in all breast cancer cell lines analyzed by Western blot but their intensity is variable. B. Immunoblotting with 27.B1 antibody of total cell lysates prepared from SK-BR-3 cells. 27.B1 antibody was preincubated with recombinant GIPC1 protein prior to blotting (lane 1), and compared to non-preincubated control (lane 2).<p><b>Copyright information:</b></p><p>Taken from "A human monoclonal autoantibody to breast cancer identifies the PDZ domain containing protein GIPC1 as a novel breast cancer-associated antigen"</p><p>http://www.biomedcentral.com/1471-2407/8/248</p><p>BMC Cancer 2008;8():248-248.</p><p>Published online 24 Aug 2008</p><p>PMCID:PMC2529336.</p><p></p
