ERBB2 and breast carcinoma: Functional analysis suggests that miR-326 is a potential tumor suppressor that regulates ErbB/PI3K signaling by targeting a network of genes (EGFR, ErbB2, ErbB3, AKT1, AKT2, and AKT3) linked to these pathways and therefore, possibly controls breast cancer cell proliferation, EMT, migration, and invasion.
