Results indicated that 116 and 95 genes (proteins) for all patients and 142 and 191 for ER-positive subgroup matched the database and were used to construct the PPI network between GATA3 mutant tumor and normal tissues (Fig. 3) and between GATA3 non-mutant tumor and normal tissues, respectively (Fig. 4). Here, GATA3 is linked to neoplasm.
