While EGF-receptor expression was almost abrogated in the SW-13 tumor model (1.2 ± 0.2%; p < 0.001 vs. MUC-1) a significant higher expression was detectable in MUC-1 tumors (100 ± 0%) compared with all other tumor models (NCI-H295R: 44.5 ± 4.1% and SJACC-3: 45.9 ± 4.9%; both p < 0.001vs. The gene discussed is MUC1; the disease is neoplasm.
