ERBB2 and thyroid gland carcinoma: We found that, as compared to the other 1024 cancer cells, the overall EGFR expression in 12 thyroid cancer cells is significantly overexpressed with 1.7-folds (thyroid cancers versus other cancers = 7.302 ± 0.24 versus 6.53 ± 0.03 fluorescence intensity-log2, P = 0.017), whereas the overall expressions of ERBB2, ERBB4, and EGF show similar expressions in all cancer cells.
