The aim of this study was to evaluate the role of EGFR treatment depends on EGFR vIII-variant in HNSCC cell lines.
First we transfected 3 HNSCC cell lines with the p-LERN vIII plasmide vector containing cDNA for EGFR vIII. Secondly the cell lines were treated with cetuximab, AG1478, Gefitinib and with 2 Gy. EGFR-Inhibition was evaluated in a combined treatment regimen as well. The survival, proliferation and migration of HNSCC wildtype and vIII cell lines was assayed using a colony formation assay, a crystal violett assay and a scratch migration assay. EGFR signalling pathway were visualised by western blotting.
EGFR vIII does not influence the response of treatment of any HNSCC cell line in vitro. Furthermore the combined regimen of treatment did not cause an additional significant decrease compared to monotherapy. Best inhibitory effect on all cell lines had Gefitinib.
