    ATCC ductal carcinoma cell line mda mb 435s
    Analysis of EGFR expression levels and binding affinities of sdAbs to human EGFR-presenting cells. Whole-cell lysates of exponentially growing cells (A431, FaDu, <t>MDA-MB</t> <t>435S)</t> were prepared and equal amounts of total cellular proteins were separated by SDS-PAGE on 10% polyacrylamide gels. After Western Blot transfer onto PVDF membranes, EGFR and β-actin proteins were detected by incubation with the respective specific antibodies followed by HRP-coupled antibodies and chemiluminescence detection (A) . In vitro specificity of 99m Tc-7C12 and 99m Tc-EG2 on A431 and FaDu cells was investigated after 1 h incubation on ice (B) . Binding of radiolabeled sdAbs was blocked by 40-fold excess of unlabeled Cetuximab. Binding data is expressed as percent of injected dose per mg protein (% ID/mg protein). NB = non-blocked, B = blocked. For in vitro binding studies, two dimensional cultures of A431, FaDu and MDA-MB 435S cells were incubated with increasing concentrations of 99m Tc-7C12 (C) . Total binding was measured in the absence of and nonspecific binding in the presence of 1 mM unlabeled sdAb. Specific binding was calculated as the difference between total and nonspecific binding. Binding studies were repeated twice and representative saturation curves for the EGFR-positive cell lines A431 and FaDu are shown. For the EGFR-negative cell line MDA-MB 435S, no specific binding was observed.

    Effect of integrin αV knockdown on cell sensitivity to antitumor drugs, PTX-induced apoptosis, cell proliferation, growth, spreading and migration. (A) Clones 2αV and 3αV demonstrate decreased sensitivity to cDDP and increased sensitivity to VCR and PTX as compared to parental MDA-MB-435S cells.

(A) Protein–protein interaction network of components identified by MS in IACs isolated form MDA-MB-435S cells. Shapes represent identified proteins and are labeled with gene symbols, arranged and colored according to their functional group as indicated (CMSC). In case of multiple functional terms assigned for each protein, the molecular function assigned by both databases has been chosen for interpretation of results. (B) Total identified IAC proteins in MDA-MB-435S cells (number of spectral counts ≥ 4, FDR < 5%, probability for protein identification ≥ 99.9%) were annotated using David GO database. To determine the sample enrichment, P -values related to GO terms of cellular components (GOTERM_CC_DIRECT), were used. Analysis of gene ontology terms was performed using REViGO tool. Statistically significant GO terms ( P = 0.05) were presented from highest P -value (bottom) to the lowest (top). (C) Volcano plot of MDA-MB-435S versus 2αV (red) and 3αV (black). To determine the significantly changed proteins −Log (FDR) ≥ 1 and fold change ≥ 1.5 were used.

    Effect of integrin αV knockdown on cell sensitivity to antitumor drugs, PTX-induced apoptosis, cell proliferation, growth, spreading and migration. (A) Clones 2αV and 3αV demonstrate decreased sensitivity to cDDP and increased sensitivity to VCR and PTX as compared to parental MDA-MB-435S cells. Cells were seeded in 96-well plates and 24 h later treated with different concentrations of cDDP, VCR, and PTX. Cytotoxicity was measured by MTT assay. Results presented are representative of three independent experiments with similar results ± SD. Data were analyzed by unpaired Student’s t -test. ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001. (B) Clones 2αV and 3αV upon PTX treatment demonstrate increased apoptosis as compared to MDA-MB-435S cells. Cells were treated with 0.004 μg/mL of PTX for 72 h, harvested for Annexin V/PI staining and analyzed by flow cytometry to discriminate between live (lower left quadrant), apoptotic and/or necrotic cells (right quadrants). The representative data of three independent experiments yielding similar results are shown. (C) Cell proliferation in MDA-MB-435S cells and clones 2αV and 3αV. Cell proliferation was measured using ClickIT EdU assay. DNA synthesis was measured upon 2 h cell growth in medium supplemented with EdU and the amount of incorporated EdU was measured by flow cytometry. Comparison of average percentage of EdU + cells from three different experiments are shown. (D) Growth curve of MDA-MB-435S cells and clones 2αV and 3αV. Cells were seeded in 10 cm culture plates and counted on days 1, 2, and 3. The results presented are representative of three independent experiments with similar results. (E) Cell spreading of MDA-MB-435S cells and clones 2αV and 3αV. Live cell imaging was performed during 18–20 h upon seeding and cell spreading was compared using time lapse IRM images (30 min–12 h). Scale bar = 10 μm. (F) Decreased migration of clones 2αV and 3αV as compared to MDA-MB-435S cells.
