Establishment of Afatinib-Resistant Non-Small Cell Lung Cancer Cells Derived from Tumor Xenograft Model [No treatment]

This experiment aimed to indentify signifcant expression genes in afatinib-resistant HCC827 cell lines. The nude mice bearing subcutaneous tumors were administerd with afatinib at different intensities and dosages (5100 mg/kg). Finally, well-growing tumors were harvested and dissocciated by 450 units/ml collagenase IV and maintained in culture dishs. All the gene expression profiles of resistant cell lines were comapared to parental HCC827 cell.
