ERBB2 and breast neoplasm: The gene classifiers were also highly associated with transcription factor STAT group (TransFac, p-value < 0.001), and were significantly enriched in regulatory pathways such as Downregulated of MTA-3 in ER-negative Breast Tumors (Biocarta, p-value = 1.80 × 10-4) and Role of ERBB2 in Signal Transduction and Oncology (Biocarta, p-value = 2.50 × 10-3).
