Expression data of the cetuximab-resistant head and neck squamous cell lines and the parental cell lines.. Expression data of the cetuximab-resistant head and neck squamous cell lines and the parental cell lines.

The cetuximab resistant FaDuCR cell lines were established after continuous treatments with a 10 µg/mL final concentration of cetuximab. Those cells could freely proliferate in 10 µg/mL cetuximab containing medium, and were named FaDuCR. We used microarrays to detail the gene expression in FaDuCR and FaDu-parental cells to screen for transcripts correlated with cetuximab resistance. Overall design: Total RNA was purified using RNeasy Mini Kit (Qiagen), including a DNase digestion treatment. RNA concentrations were determined by NanoDrop 2000 (Thermo Scientific). RNA was labeled using the GeneChip® WT Terminal Labeling and Controls Kit combined with the Ambion® WT Expression Kit. Labeled cRNA was hybridized to GeneChip® Human Transcriptome Array 2.0 arrays (Affymetrix).
