ZNF217 and ErbB3 expression levels showed significant correlation in human breast tumors [19], and ectopic ZNF217 expression induced ErbB3 protein overexpression in normal human mammary epithelial cells (HMECs) and in breast cancer cell lines (paired with increased ErbB2 expression) [19, 20]. The gene discussed is ERBB3; the disease is breast neoplasm.
