The results show that HGUE-C-1 cells are resistant to 5-FU and irinotecan compared to other colorectal cancer cell lines, as seen in Figures 4A and B. HGUE-C-1 cells also show resistance to cetuximab (Figure 5A), despite the patient was not treated with this EGFR antibody. The gene discussed is EGFR; the disease is colorectal cancer.
